专利说明:

[0001] [0001] The present invention relates to the general domain of electronic monitoring systems, comprising an embedded box on an apparatus including at least one engine, a reservoir and an electronic supply circuit and a sedentary control instrument in which the embedded box is able to be wired or not. More precisely, the invention refers to electronic monitoring systems, aiming to monitor the fuel consumption made by the engine of the device on which the box is loaded.
[0002] [0002] The monitoring of fuel consumption is currently a particularly crucial issue, regardless of an economic point of view or an environmental point of view.
[0003] [0003] The invention therefore relates primarily to the transport of goods on roads. This sector of activity consumes several tens of thousands of liters of fuel oil annually and the share of the cost of fuel in the price of the cost of road transport continues to grow. It is shown, therefore, that the control of this spending position is currently very important to ensure the profitability of road transport companies.
[0004] [0004] The Civil Construction and Public Works sectors, due to the use of different work machines and that of the generator sets, are also mentioned, since there are also important fuel consumption.
[0005] [0005] Currently, there are programs to optimize fuel consumption. These programs are mainly used in the middle of a control instrument that is not installed on the vehicle itself. There are also those that are intended to be installed in the middle of the vehicle itself.
[0006] [0006] These program instruments generally allow the arrest or capture of data on the supply of fuel in a vehicle and the distances traveled to calculate average consumption.
[0007] [0007] Such programs make it possible to monitor consumption, make a first analysis of the types of driving, in order to compare the consumption of vehicles and the consumption associated with the types of behavior of drivers.
[0008] [0008] These programs already make drivers aware of the impact of driving on consumption, in order to make them conduct themselves more economically.
[0009] [0009] However, these fuel consumption monitoring programs only allow access to an average consumption per vehicle without being able to access more precise data on fuel consumption.
[0010] [00010] There are also embedded boxes that are able to connect to a vehicle's chrono tachograph, its GPS receiver and the CAN bus of the vehicle over which the box is loaded. This box is capable of repatriating via wires or not, for example, via a cable or via a modem, data on fuel consumption for a restitution program generated by an explorer of the fleet of vehicles mentioned.
[0011] [00011] The consumption data can then be known a posteriori or in real time by the refund program. This can give rise to decision making, depending on the observed data.
[0012] [00012] The use of the tachograph chrono allows to know the speed of the vehicle, as well as to have access to a date / time data record. The GPS receiver allows access to geolocation data. The CAN bus allows access to data from the electronic system embedded on the vehicle.
[0013] [00013] In the event, the only electronic data that circulates on the CAN bus, allowing to monitor the fuel consumption made by the vehicle's engine, is classically, a data coming from a flow meter installed on the pipeline, allowing the fuel to enter the fuel chamber or data from an equivalent system, measuring the amount of fuel that leaves towards the combustion chamber.
[0014] [00014] Currently, in the electronics shipped over vehicles, the volume of gasoline consumed is only accessible via this device.
[0015] [00015] This structure of an electronic system for monitoring fuel consumption by a vehicle allows correct monitoring of fuel consumption.
[0016] [00016] However, it is observed that currently these systems show limits. In particular, it is shown that these programs do not allow to face new behavior on the part of drivers and structured networks that organize thefts, fuel substitutions and other violations.
[0017] [00017] Above all, the known electronic monitoring systems do not provide information on the location of the violation, nor on the date and time of the violation. They do not know how to distinguish a theft from other events that may arise from the constant geographical position.
[0018] [00018] They also do not allow access, even indirectly, to the identity of the person who committed the crime, nor how that person took possession of the theft. Object and summary of the invention
[0019] • pelo menos um conector para a conexão a pelo menos um sensor específico de nível de carburante capaz de tomar medidas quantitativas de nível de carburante entre uma parede alta e uma parede baixa do reservatório e para o recebimento, pela caixa, de dados de nível de carburante proveniente desse sensor, o sensor específico sendo aferido previamente à colocação em serviço do sistema eletrônico, de tal forma que cada valor de saída do sensor é associado, de maneira biunívoca, a uma posição do nível de carburante entre a parede alta e a parede baixa do reservatório e a um volume preciso de carburante restante no reservatório, independentemente um do outro do nível de carburante entre a parede alta e a parede baixa;

- at least one watch capable of providing date / time recording data; - at least one receiver to receive geolocation data; and - at least one memory to record successive data lines, comprising fuel level data, date / time recording data and geolocation data at a specified time with a periodicity between 1 and 240 seconds; - the on-board box is adapted to feed itself next to the electrical supply circuit of the appliance, when the appliance works and to feed itself, when the appliance does not work, together with an autonomous battery, capable of recharging, when the appliance works; - the on-board box also comprises a data processing module capable of detecting a drop in fuel level with a constant geographical position from the successive data lines recorded and communicating, when a fuel drop with a constant geographical position, and therefore, for a device at standstill, an alert to the control instrument is detected, the data treatment module is also able to communicate with data lines to the control instrument; - the control instrument is able to be connected to the box shipped via wires or not and comprises at least one memory to record the alerts and data lines communicated by the box shipped, a data processing unit and a screen to display alerts and data communicated by the box shipped; - the box also comprises means for detecting the operating status of the device's motor, whether the motor running status data is included in the data line to be processed by the data processing module, in order to include engine operating status data in the alert communicated to the control instrument; - the control instrument thus determining the motor times connected to the device at stop and the times of the motor connected with the device in motion.
[0020] [00020] In the sense of the invention, the terms "device at stop" means that the device has a zero speed. With this monitoring system that uses a fuel level telemeter, the onboard box periodically has access to a quantitative measurement of the actual fuel level in the reservoir, thanks to the presence of a quantitative fuel level sensor installed in the reservoir. As these fuel level data are permanently coupled in real time with the geolocation data and the date / time recording data in the same data line, the invention allows real-time monitoring of the fuel reservoirs.
[0021] [00021] According to the invention, this fuel level sensor is previously calibrated to take quantitative fuel level measurements between a high wall and a low tank wall. In fact, the invention is such that the specific sensor is checked prior to putting the electronic system into service, in such a way that each sensor output value is associated, biunivocally, to a position of the fuel level between the high wall and the low wall of the tank and an accurate volume of fuel remaining in the tank, regardless of the level of fuel between the high wall and the low wall. This feature is not accessible with the rods usually installed in the reservoirs. In fact, the known rods are generally tubular or levered rods, measuring the level by level. From 18 to 21 millimeters in height. In addition, the known rods generally allow the level to be measured quantitatively over only 80% of the height of the reservoir excluding the upper part.
[0022] [00022] It is noted here that currently the fuel rods, as used in vehicles and sending their measurement data on the CAN bus of the vehicles are not checked, in order to allow a quantitative measurement of the fuel level. They allow, above all, an indicative measure, allowing only to follow the decrease in the fuel level, once only a certain amount of fuel remains, after which the dipstick begins to show a decrease. The known gasoline rods, in effect, generally remain for a certain time at the maximum level following a flood, before the rod indicates a progressive decrease in the fuel level. The purpose of this indication is to effectively prevent the user from falling into a panic and not to monitor the decrease in fuel level in real time.
[0023] [00023] The invention requires that an interface be installed between a rod and the box, according to the invention, to perform the quantitative calibration of the rod that is dedicated to the application of the invention, that is, a rod previously installed for another one purpose, notably indicative.
[0024] [00024] The invention then proposes the use of quantitative data from the fuel level sensor in combination with geolocation and timestamp data, these data being recorded together for a specific time with a determined periodicity. They are known in the middle of the box shipped, according to the invention, regardless of the state of operation of the apparatus on which the box is loaded.
[0025] [00025] In effect, the power supply system of the embedded box uses either a connection to the electrical supply circuit of the device, or a connection to an autonomous battery that recharges when the device works. This makes it possible to ensure the storage of data with strictly the same periodicity, regardless of the state of the device, included there at the device stop.
[0026] [00026] This characteristic is unknown to electronic monitoring systems, such as currently known, since it is never expected that data will be recorded outside the operation of the device on which all or part of the electronic monitoring system is loaded.
[0027] [00027] The combination between the control of the electrical supply of the on-board box and the storage of data specific to the invention with fixed periodicity authorizes to make a strict monitoring of what unfolds in the reservoir. This allows, according to the invention, the use of the data processing module capable of detecting a drop in fuel level with a constant geographical position from the successive data lines recorded, regardless of the state of operation of the device.
[0028] [00028] Indeed, the permanent supply of the on-board box proves to be indispensable to use this detection, which, if not, would absolutely not be reliable or would run the risk of not identifying events.
[0029] [00029] It is observed, therefore, that, in addition to the fact of being able to know the consumption by driver or by vehicle, as it is already partially allowed by the devices previously known, the invention allows to be informed continuously and permanently the presence of a drop in the fuel level with a constant geographical position, knowing the date, the location and the volume of fuel corresponding to the drop in the fuel level.
[0030] [00030] In addition, the invention allows to completely control the need or not to fill the vehicles' tank with fuel, before they leave from a logistics center that has its own fuel tank. Indeed, the invention allows access to real-time information on the volume present in the reservoirs. This generates a saving of time, as this allows the trucks that have sufficient fuel to start, in a guaranteed way, and this reduces the waiting line in front of the tanks. It is common to observe these queues of several hours when trucks leave in the morning on certain road transporters. This necessarily generates an economic gain.
[0031] [00031] In fact, none of the known devices allows access in real time to the real fuel level in the middle of one or more tanks. In fact, in the known devices, only the consumption of the vehicle is known with the help of data relating to the amount of fuel that leaves towards the combustion chamber, for example, thanks to the use of a flow meter. Also, only an approximation can be given depending on the average consumption from the last flood.
[0032] [00032] More generally, the invention provides knowledge of the actual consumption of vehicles, deducting fuel drops with a constant geographical position that can only correspond to a siphoning of the reservoir. This makes it possible to deduct fuel thefts from the calculation of actual consumption and, therefore, the environmental impact of a company on CO2 emissions, the main greenhouse gas, which are directly linked to actual fuel consumption.
[0033] [00033] The invention naturally makes it possible to identify the liters lost for some reason independently and, therefore, calculate the financial losses due to the liters of fuel paid for and not consumed by the company's vehicles.
[0034] [00034] The invention makes it possible to eliminate events with the engine connected to the device when fuel falls are stopped in a constant geographical position. Indeed, in the event that the system is not in a position to know the state of operation of the engine, it cannot dissociate a theft from normal consumption of the engine that turns at stop. The invention, therefore, allows a great finesse in determining the events of fuel drops and their nature. In this case, it must be stressed that the motor state in operation is different from the position of the contact switch. In effect, the contact switch can be in the on position, while the motor does not turn. In that case, no fuel consumption would be observed. The invention is interested in the case by the engine turning.
[0035] [00035] Finally, it should be noted that the characteristic according to which an alert is provided to the control instrument to which the embedded box can be connected can take different forms, ranging from simple consideration to an alert in good and due sound or visual form. real time or deferred time. In the case of a deferred alert, notably when the box must be connected to the control instrument to provide it with data, it is observed that the treatment of the data advantageously carried out on the box may, in a degraded mode, be carried out in the middle of the control instrument , after receiving the data lines.
[0036] [00036] Thanks to the date / time stamp data, the invention makes it possible to know exactly the date and time at which a siphon was made. In fact, the drop in fuel with a constant geographical position clearly reveals a siphoning of a reservoir. The geolocation data also gives the position of the vehicle at the time of theft. The data on the running state of the engine allows to eliminate the time events of the engine connected to the device in stopping the theft events themselves.
[0037] [00037] Furthermore, knowledge of the rotary engine data, in the event that, in addition to the disappearance of the fuel, the kinetics of the disappearance of the fuel signs the presence of a theft, also reinforces the evidence of guilt of the driver responsible for the vehicle in the fuel drop. In addition, this also makes it possible to identify unproductive consumption such as vehicles when the engine is stopped.
[0038] [00038] In fact, an additional advantage of having access to the operating state of the engine is the possibility of accessing the times the engine is connected to the device at the stop with, directly associated, the place, the day and the time when this occurred. The invention gives access not only to the duration that the engine remained on at the stop, but also at the beginning of that event, as well as at the end of that event. It is known, therefore, a running duration between two precise dates, thanks to the date / time record. It is not a matter of calculating an average of excessive consumption, using a kilometer index questioned between two points or comparing it with theoretical consumption, using the data from the CAN bus of the device. However, the data from the CAN bus can be compared to the data obtained with the invention. The same happens with data from other instruments, such as the tachymeter chronometer, which can, in parallel, release the distance covered, the work, rest and speed times, the driver's identity. RFID-type solutions can also be used.
[0039] [00039] The box may, in particular, be connected to these instruments itself. It will then be possible to upload the information available on these instruments without an intermediary box and cross-check all that information.
[0040] [00040] With the invention, the motor times connected with the device at the stop are precisely known and located in time and space. This is accessible when the device is in operation or not. The distinction between these two types of fuel drop at the stop is a very interesting fact, as it allows not accusing a driver without a reason for theft and conversely not failing to point out an inappropriate behavior to fuel savings.
[0041] [00041] This then makes it possible to rectify the behavior of a private driver who would tend to let his engine run thus generating not only costs for the company, but also CO2 emissions which is perfectly desirable to decrease all the more the more companies are currently particularly inclined. to provide environmental performance data in their favor.
[0042] [00042] Thus, the invention helps road freight transport companies to reduce their fuel consumption and also to jettison part of the fuel station in their accounts, in addition to allowing them to monitor fuel thefts. Companies can then also subscribe to charters, which allow voluntary engagement from an environmental point of view.
[0043] [00043] In particular, the letter "CO2 objective": transporters engage ... "can be signed by companies that will be equipped with the monitoring system, according to the invention, in order to enhance their engagements internally and externally.
[0044] [00044] The monitoring system, according to the invention, allows to effectively carry out an accurate and effective measurement of consumption and actual CO2 emissions, excluding or not fuel theft, according to the desired information and identifying unproductive consumption with the vehicles at engine stop which can be reduced by driver education.
[0045] [00045] Thanks to the recurrence, its fuel level measurement records and the combination with geolocation data, date / time recording and engine operating status, the invention allows to release CO2 emission calculations by geographic zone in precise periods, either by customer of the carrier, or by vehicle and / or driver.
[0046] [00046] The crossing of vehicle location information and movement of the connected motor vehicle thus allows an optimal monitoring of the drivers' behavior and fuel consumption. They therefore allow you to know the points on which improvements can be made and actions as well.
[0047] [00047] In addition, as the embedded box operates independently of the state of operation of the device on which it is embedded, the control instrument has access to the engine off times, the engine on time with the device at stop and the engine times on with moving device. The invention thus allows to have a measure of the total consumption on the paths made. This allows targeting actions in a numbered and realistic reduction objective based on the perfect knowledge of consumption by vehicles and / or drivers that define an initial location state.
[0048] [00048] Naturally, the embedded box, according to the invention, allows, in addition, to access the detail of distance traveled, the visualization of the road on digital cards, as well as to have access to the vehicle stops.
[0049] [00049] According to the particular embodiments of the invention, the means for detecting the operating state of the motor are chosen from a connection with the sensor placed at the level of the excitation terminal of an alternator of the electrical supply circuit of the device, a connection over a body socket, giving the information to the rotating engine, a connection to the battery to measure the voltage difference at the terminals of the main battery, the data processing module previously knowing the voltage difference observed between the voltage observed with a contact switch position on ON and the voltage observed with the motor running.
[0050] [00050] These different ways of knowing the engine's operating state give a safe result, allowing to know if the engine spins and consumes fuel or if it is switched off and therefore does not consume more fuel.
[0051] [00051] According to an advantageous feature of the invention, the box's data processing module is capable of detecting a fuel level rise with a constant geographical position characteristic of filling the reservoir from the successive recorded data lines and communicate, when a fuel lift with a constant geographical position is detected, in real time or in deferred, a specific signal to the control instrument, to signal the presence of a filling.
[0052] [00052] This characteristic allows to mark, in a set of data lines, the moments of filling the reservoir regardless of whether it is full or only a relative elevation of fuel in the reservoir. This feature also makes it possible to know the location, date and time of each reservoir full or filling with a visualization on a card.
[0053] [00053] This feature allows the user of the control instrument to have the dates and times of filling the reservoir and the quantity actually delivered in the middle of the reservoir.
[0054] [00054] This feature is useful to not only mark the fillings / fillings in time, but also to confirm the presence of a fuel replacement as this is sometimes observed.
[0055] [00055] In fact, a drop in the level of the fuel with a constant geographical position followed by an increase in that level with a constant geographical position, regardless of the same position or a different position from the fuel reduction observed previously, or possibly the opposite, will be fully characteristic fuel replacement.
[0056] [00056] According to a particular characteristic of the invention, the control instrument, in addition, a data-taking interface to allow a user to take external data related to the reservoir fillings, the treatment unit being adapted to receive those external data taken , to detect inconsistencies between the external data taken by the user and the specific signals to the fillers communicated by the box shipped.
[0057] [00057] In combination with the previous feature, this feature allows theft to be detected in the tank. These thefts are, for example, made by filling a front container, during or following the filling of the vehicle's reservoir on which the embedded box of the electronic control system, according to the invention, is installed.
[0058] [00058] Indeed, comparing the increase in the fuel level observed and detected in the middle of the box shipped and marked by the specific signal sent to the control instrument with the data taken from the control instrument with the data and indicating the amount of fuel paid for, usually announced on the receipt provided by the service station, in which the reservoir was filled, on the same date and at approximately the same time, the control instrument has access to the amount of fuel that was then poured into another container that the device reservoir on which the electronic system's embedded box, according to the invention, is installed.
[0059] [00059] In addition to the location, the date, it is thus understood that the electronic monitoring system, according to the invention, allows to know how the missing fuel has been diverted. In fact, when a fuel drop with a constant geographical position is observed, it will be a siphon and when the comparison between the amount of fuel paid in a tank filling expense note and the measured amount of fuel, when a fuel level rise reveals an inconsistency, a theft in the tank will be detected.
[0060] [00060] Also thanks to this control instrument, it is thus possible to know where, when and how a thief acted to steal fuel.
[0061] [00061] According to an advantageous feature of the invention, the registration period for the data lines is between 60 and 120 seconds.
[0062] [00062] This registration periodicity allows a rough compromise to be made between fluctuations in the level of fuel that is capable of being detected in the middle of the reservoir and a sufficient end of level sample in the reservoir to allow the detection of a fuel drop with a geographical position. constant, as it is intended by the invention. Fluctuations in the reservoir can be notably due to vehicle accelerations and decelerations.
[0063] [00063] According to a preferred feature of the invention, the registration period of the data lines is between 85 and 95 seconds.
[0064] [00064] The inventors noticed, in fact, that a chosen time interval of around 90 seconds allows to optimally get rid of the level fluctuations, due to the acceleration and deceleration of the vehicle and this measure every minute and a half allows a very reliable monitoring of driver behavior.
[0065] [00065] This allows the electronic monitoring system, according to the invention, to provide an optimum amount of data, neither too low, nor too considerable to monitor the actual consumption by the vehicle, reliable and sufficiently accurate for observations on the level. of fuel in a tank made, on the other hand, in the middle of the control instrument.
[0066] [00066] In effect, this measurement made with a chosen period of around 90 seconds allows to avoid having to make an average of the fuel level, since a fluctuation, due to an acceleration or a deceleration is observed.
[0067] [00067] In fact, when a sample is made with a period of less than 60 seconds, it is observed that it is necessary to average the level indicated by the sensor, under penalty of not detecting certain fuel drops with constant geographical position or detecting false ones fuel falls with a constant geographical position.
[0068] [00068] The calculation of this level average mobilizes the calculation resources in the treatment facilities. This may be desirable to avoid for reasons of economy or speed of calculation.
[0069] [00069] Thus, the optimization of the periodicity of the data line records is particularly important in the scope of the invention and a choice of around 90 seconds proves to be particularly suitable.
[0070] [00070] According to an advantageous feature, the box also comprises a connector to be connected to at least one contact switch position detector and the fact that the data from that detector is included in the data line and is handled by the data processing module in order to include the contact key position data in the alert communicated to the control instrument.
[0071] [00071] This feature allows to know if the driver remained in the vicinity of the vehicle when a fuel drop is detected. Indeed, when a vehicle is stolen, people who perform this act generally take precautions to be able to share easily and without wasting time. Thus, it can be seen in general that the contact switches generally remain in the “On” position even if the engine continues to turn when siphoning the vehicle's tanks. In this case, the kinetics of the disappearance of the fuel with the engine running allows to dissociate the theft from a simple consumption when the engine stops turning.
[0072] [00072] The presence of this contact key position data allows the operator in which the control tool is installed to have additional evidence to characterize fuel theft and, above all, to identify the person responsible, since the key Contact information is usually released to a private driver at the beginning of the course and returned by the latter at the end of the course. If the contact key has been left in the “ON” position, when the reservoir falls in a constant geographical position, the driver in question will hardly be in a position to state that he is not responsible or that he ignores the performance of this small theft .
[0073] [00073] In accordance with a particular characteristic of the invention, the box comprises a module for gauging the fuel level sensor chosen from the sensors of the ultrasonic type, the sensors using a float, the gauging automatically associating in a biunivocal manner, prior to placement in service of the electronics, a sensor output value at each position of the fuel level between the high and low walls of the tank and a precise volume of fuel remaining in the tank.
[0074] [00074] This feature allows each observed fuel level in the reservoir to be associated with a sensor output value, automatically ensuring the quantitative character of the measurements made by the fuel level sensor. The use of this automatic gauging module is interesting, but a manual gauging can also be performed on each type of tank to associate a fuel volume that remains with a sensor output value.
[0075] [00075] According to an advantageous feature, the data processing unit of the control instrument is adapted to calculate the actual consumption of the device from the recorded data lines.
[0076] [00076] According to another advantageous characteristic of the electronic system, according to the invention, the data processing unit of the control instrument is adapted to calculate a carbon oxide emission made by the device.
[0077] [00077] This calculation allows you to directly access the carbon balance of the activity carried out by the device, which can participate in a commercially valued operation with shipper customers, who are increasingly sensitive to environmental issues. This can also contribute to giving an image of a modern company respectful of the environment and being part of a perspective of sustainable development. Overall, this could lead to a better image of road transport.
[0078] [00078] According to an advantageous feature of the invention, the apparatus that has an additional work function to the operation of its motor, the box comprises means to determine the operating state of that additional work function, the operating status data of the additional work function being included in the data line, the control instrument thus determining the times of the motor on with the device at stop during work and the times of motor on with the device at stop outside of work.
[0079] [00079] This working status data of a working function allows to decouple the times of the motor on with the device in the productive stop, that is, the times of the motor on with the device in stop of the work and the motor on with the device in the unproductive stop, that is, without work. Indeed, for certain particular actions, specialized vehicles must have the engine running in order to carry out the work function. In this case, the motor times connected with the device at the stop should not be counted among the unproductive consumption. This characteristic makes it possible to dissociate these two cases.

[00093] In the figures: - figure 1 schematically shows an electronic monitoring system, according to the invention; - figure 2 shows an example of successive data lines recorded in the middle of the box loaded and downloaded on the control instrument before being displayed there in the form represented in that figure; - figures 3A and 3B show an example of parameterization of alerts to indicate a drop in the fuel level in a constant geographical position and a specific signal indicating the presence of a reservoir filling in a constant geographical position and an example of displaying alerts overconsumption; - figures 4A, 4B, 4C and 4D show tables and graphs, in which abnormal overconsumption events are detected; figure 5 shows an example of sensors using a float capable of being used for the application of the invention; figure 6 shows a table resulting from a measurement of the fuel level sensor, according to the invention; figure 7 shows a flow chart of the method, according to the invention; - finally, figure 8 shows a card capable of being formed in the control instrument for the management of a fleet of vehicles or a group of drivers.
[0094] [00094] Figure 1 schematically represents an electronic monitoring system, according to the invention. This system comprises a box 10 loaded on an apparatus including at least one motor 11, a reservoir 12 and an electrical supply circuit.
[0095] [00095] This electrical supply circuit typically comprises a battery 13 and several means of connection for the motor 11, notably to recover the energy dispensed by it through an alternator. In general, the battery 13 is, in addition, connected to a plurality of sensors generally present on board the apparatus 1, either directly or via the housing 10.
[0096] [00096] Thus, battery 13 is connected to box 10, itself connected to a fuel level sensor 14 capable of making quantitative fuel level measurements in reservoir 12 between the high and low walls of that reservoir 12.
[0097] [00097] The sensor 14 is also connected to box 10 in such a way that it can transmit the fuel level data that it is in a condition to acquire. For this purpose, box 10 comprises a connector 101. This connector, which allows data transmission, also takes advantage of the power supply of sensor 14 via box 10.
[0098] [00098] According to the invention, the box 10 also comprises a power connector with oscillation 102, capable of oscillating the supply of the box 10 between the electrical supply circuit of the device 1 and, therefore, by a supply direct by battery 13 and an attached and autonomous power circuit based on the implementation of an attached battery 15. The battery 15 is advantageously connected to the box 10, itself connected to the main battery 13. Thus, this attached battery 15 is able to recharge on the electrical supply circuit of the device 1, when the motor 11 operates and supply the electric energy to box 10, since the electrical supply circuit of device 1 is switched off.
[0099] [00099] Box 10 further comprises a data processing module 104, a clock 103, capable of supplying date / time recording data to data processing module 104, a receiver 105 for receiving geolocation data and a memory 106.
[0100] [000100] Memory 106 is notably used, according to the invention, to record successive data lines, comprising fuel level data from sensor 14, date / time data from clock 103, geolocation data from the receiver 105 at a specified time with a period between 1 and 240 seconds.
[0101] [000101] According to the invention, the periodicity of recording the data lines will advantageously be between 60 and 120 seconds in order to eliminate the most rapid fluctuations in the fuel level in the middle of the tank 12. The periodicity of 120 seconds allows to have a sampling of the fuel level sufficient to mark the acts that the monitoring system, according to the invention is intended to detect.
[0102] [000102] More precisely, the range of optimal periodicity allowing to optimize, at the same time, the amount of data stored, the suppression of oscillations in the reservoir and the detection of the desired events is between 85 and 95 seconds.
[0103] [000103] Box 10 of the system can be installed advantageously inside the dashboard.
[0104] [000104] The electronic monitoring system, according to the invention, also comprises a control instrument 2 equipped with a memory 20 to record the alerts and data lines communicated by the embedded box 10, a data processing unit 21 and a screen 22 to display the alerts and data communicated by the onboard box 10.
[0105] [000105] Advantageously, the control instrument also comprises a data-taking interface 23, allowing the user to take external data related to the filling of the reservoir 12.
[0106] [000106] Figure 2 shows a number of data lines, such as, registered with a periodicity of 90 seconds, when a vehicle is operated followed by the monitoring device, according to the invention.
[0107] [000107] The message transferred from the box to the control instrument has the following format: ymmddnnn, ddmmaaaa, hhmmss, xxxx.x, yyyy.y, zzzz.z, ABCDEFrr, IJKLMOPr, sss.s, ddmm.mmm, S, dddmm.mmm, W, cc.cccc, tt.t, tt.t, tt.t.
[0108] [000108] This format is interpreted as follows: Vehicle identification - serial number: ymmddnnn, Date: ddmmaaaa, Time: hhmmss, R1 liters: xxxx.x, R2 liters: yyyy.y, R3 liters: zzzz.z, State 1: ABCDEFrr, state 2: IJKLMOPr, nanometer / hour speed: sss.s, Latitude: ddmm.mmm, Latitude: S, Longitude: dddmm.mmm, Longitude: W, Client interface (EcoG, for example): cc.cccc, Temperature 1: +/- tt.t, Temperature 2: +/- tt.t, Temperature 3: +/- tt.t,
[0109] [000109] The data sending speed is programmable between 4800, 9600 and 19200 bauds per second.
[0110] [000110] The set of information provided by the CAN bus, the vehicle's chrono tachograph and at least one RFID module can be added to this plot.
[0111] [000111] This table shows, based on geolocation data, identified with Loc1 and Loc2, that the vehicle traveled between 21:06 and 21:27. The fuel level logically decreases as the vehicle moves. However, it is noted in this case the observation of this de-description is conditioned by the sensitivity of the sensor 14 implemented in the reservoir 12.
[0112] [000112] It is also noted that the control instrument has access to sensor states that provide information about the motor's operation and the position of the contact switch. Other possible states available, thanks to other sensors installed on the vehicle, can also be included in data lines of the type shown in figure 2. In case state 1 informs us that the contact key is in the ON position (according to state data 1: 0 = ignition ON) and the vehicle's engine is started (fourth state data 1: 1 = engine on). Figures 3A and 3B show the parameterization of the limits of overconsumption alert and detection of a reservoir filling respectively. These limits are able to trigger an alert as long as they are exceeded in the constant geographical position. To perform this detection, the data processing module makes a comparison between the fuel level observed on two or more successive lines and compares it with the maximum parameterized flows in the middle of the box, as shown in figure 3A.
[0113] [000113] Advantageously, as shown in figure 3, maximum flows are indicated for different states of engine operation and vehicle displacement. Choosing a parameterization of superconsumption adapted to the average consumption of the vehicle avoids triggering false alerts and allows selectively detecting superconsumption.
[0114] [000114] The invention provides, in effect, that the data processing module makes several comparisons between two lines of data registered at the beginning and at the end of a constant geographical position.
[0115] [000115] Figure 3B shows a number of detected over consumptions, such as displayed on the control instrument screen. The observed super consumptions are associated, each one, to an exploration site (Marseille, Toulon or Nice) of several vehicles marked by their inscription. The alert was previously sent to the control instrument 2 by the boxes 10 installed on the vehicles mentioned.
[0116] [000116] The control instrument 20 then displays overconsumption in the format shown in figure 3B which shows the location of exploration, the inscription of the vehicle referred to, the date and time of observation of the observation of abnormal overconsumption, the volume of observed description, as well as the code of the driver who was, at that moment, behind the wheel of the vehicle bearing the mentioned inscription.
[0117] [000117] Thus, it is possible to follow, very finely, any theft of fuel in a specific vehicle and to be able to specify the time at which that theft was perpetrated, as well as the location, which is not in the case specified, but which is known on the lines data, as communicated to the control instrument. It is also possible to decouple a theft from overconsumption due to an engine running on the device at the stop.
[0118] [000118] Until now, it was not possible to detect this theft and give it the characteristics, because the use of a flow meter or a measure of the amount of fuel spent towards the engine to measure consumption does not in any way allow to detect the date and time of a theft.
[0119] [000119] Indeed, in known devices, it is possible to know the fuel consumption at every moment, it is not possible to follow in real time the amount of fuel in the vehicle tank and this prevents the detection of thefts by siphoning.
[0120] [000120] Figures 4A, 4B, 4C and 4D show examples of, respectively, data lines in the middle of which a theft is detected, a fuel level layer with constant geographical position, showing a siphoning theft, such an alert as shown on the control instrument and a fuel level monitoring curve with vehicle displacement and on which suspicious events appear.
[0121] [000121] In figure 4A, it can be seen that the truck makes a small visible displacement over the geolocation data, before immobilizing in a record / data line 7. Then, the volume V1 of the reservoir has according to the successive records 9 to 12, decreased by 41 liters without moving the vehicle. This typically means the occurrence of a siphon, the amount disappeared due to the duration of the stop being greater than the consumption of a motor turning at stop.
[0122] [000122] Furthermore, in addition to the theft problems, it is observed that, since access to the states of the contact key and the motor, at the same time as the geolocation data, it would be possible to detect overconsumption due to the fact that the driver have let the engine run at the stop. It is even possible to give a result in the form: the vehicle remained 20% of the overall engine running time at stop.
[0123] [000123] As shown in figure 4B, the control instrument can calculate and display a fuel level curve according to the successive registers. The curve in figure 4B shows graphically the theft detected in the table in figure 4A.
[0124] [000124] Figure 4C shows an example of displaying the “theft” alert associated with visible theft on the data table in figure 4A. The control instrument may also eventually display the locations of the events observed on a map. It can also provide any kind of consumption statistics on more or less important slots.
[0125] [000125] Figure 4D shows an example of a fuel level curve on which suspicious events are detected. It is thus seen that VM zones on the curve correspond to the vehicle in motion by correlation with the geolocation data. In this case, a VA zone is also observed in which the vehicle is stopped. There are also two suspicious events E1 and E2 in which the fuel level has dropped rapidly. In the event that the vehicle is found immobilized in the moments corresponding to these records, thanks to the geolocation data, a theft is detected.
[0126] [000126] Figure 5 shows a sensor with float 14, capable of being used in the invention. It is noted in the case that other types of sensors, for example, sensors with ultrasound, can be used to apply the invention, since a quantitative measure of the fuel level can be acquired between the high wall of the tank and the low wall of it. There are also tubular type sensors where the float is wrapped around an axis of the sensor and which can be used in the middle of a device, according to the invention.
[0127] [000127] The sensor 14, shown in figure 5, has a fixing disc 140 on the reservoir, a longitudinal body 141, intended to be placed vertically in the reservoir and advantageously adjustable in its length to be able to adapt to different reservoir sizes, a lever arm 142 provided at its end with a float 143. The lever arm 142 is articulated about an axis 144 placed on the low end of the body 141 of the sensor 14. In the example shown, the height L of the body 141 of the The sensor can be adjusted using screws placed in holes placed for this purpose along the body 141.
[0128] [000128] The length R of the lever arm 142 of the float 143 can also be modified depending on the location where the float 143 and the fixing axis 144 are attached on the sensor body.
[0129] [000129] Thus, the installation of the sensor comprises two stages. The first consists of regulating the length L of the body 141 in such a way that it is equal to 50% of the diameter H of the reservoir, when it is cylindrical or 50% of the height H of the reservoir when it is cubic, square or rectangular. Then, the position of the float 143 on the lever arm 142 is adjusted, so that when the float arm 142 is in the position of the full reservoir, the upper wall of the float 143 is at the height of the high wall of the reservoir.
[0130] [000130] Furthermore, in the case where this sensor is used, it is necessary that, for the low position of the float 143, that is, the position in the lowest rotation, the float 143 touches the low wall of the reservoir 12.
[0131] [000131] It is also necessary for the invention that the high rotational position is quantitative for the highest possible fuel levels in the tank 12. For this, it is necessary that the float 143 is always in a floating position and cannot be sheared against the high wall. The float and the various sensor elements will be sized for this, even if a margin of error above and below the reservoir can eventually be accepted. However, ideally, the shape of the reservoir and the position of the filling hole will be such that the float 143 cannot be placed on the high wall.
[0132] [000132] As shown in figure 5 and described above, the height L of the sensor body 141 between the high wall of the reservoir 12 and the articulation axis of the lever arm 142 and the complement R of the lever arm 142 will, in the reality, chosen according to the height H of the reservoir 12.
[0133] [000133] Fuel level sensors with adjustable arm can thus be used in the middle of the tanks of the devices on which the invention will be installed.
[0134] [000134] Figure 6 shows a table in which examples of different calibration points are listed associating the output signal, identified with SC, from sensor 14 with the amount of fuel present in reservoir 12. This table may be the result of a manual calibration or an automatic calibration.
[0135] [000135] The advantage of manual calibration is its precision and reliability, since the amount of fuel introduced in the tank 12 is completely controlled. It is thus possible to associate precisely an output signal SC from sensor 14 corresponding exactly to the amount of fuel present in the reservoir.
[0136] [000136] In order to perform a manual calibration, it is necessary that the reservoir be previously emptied and disconnected from any other reservoirs present on the device under consideration. The lack of connection between the reservoirs prevents, in effect, when calibrating, the fuel from the other reservoirs filters up to the reservoir in the course of calibration or vice versa. In all cases, it is necessary that the box 10 is connected to its power source and that the sensor is also connected to box 10.
[0137] [000137] The float 143 must certainly be installed correctly in the reservoir 12 and the movement of the arm 142 of the float 143 must be able to be done without obstacle over the entire height of the reservoir 12.
[0138] [000138] Finally, it is necessary that the reservoir 12, which will be calibrated, be well identified in the middle of box 10. Advantageously, the maximum capacity of the considered tank will also be indicated next to box 10.
[0139] [000139] It is noted in the case that the calibration can be done through the user interface present on the control instrument. This is an advantageous achievement. However, an attached device could be used to perform this operation.
[0140] [000140] This attached device or control instrument is, in any case, able to program box 10, indicating the identifiers of the connected reservoirs, their maximum capacity and their position.
[0141] [000141] Anyway, manual calibration of the reservoir is necessary so that the monitoring system gives the maximum reading accuracy of the fuel levels in the reservoir.
[0142] [000142] This operation starts with an empty tank and it is necessary to stop several times to capture the signal at the level sensor output and add a new data line to the calibration files according to the amount of fuel that was introduced in the tank.
[0143] [000143] A file is then generated, describing precisely the float and the reservoir in addition to the calibration points that associate the sensor signal with the amount of fuel.
[0144] [000144] This file of the type shown in figure 6 is then used for subsequent installations on vehicles with similar configurations of floats and reservoir sizes.
[0145] [000145] Indeed, according to the invention, it is possible to calibrate the tank automatically. It is then a matter of downloading a calibration file, from an attached device or more preferably, from the control instrument. In this case, the calibration file will be identified by data corresponding to the size and volume of the reservoir. This calibration file is typically a file resulting from a previous manual calibration of a reservoir identical to the one to which the calibration file was downloaded.
[0146] [000146] However, this calibration will not be strictly adapted to the particular reservoir considered and may eventually generate errors in the level of the quantitative measures of fuel level. A manual calibration will then be essential.
[0147] [000147] At the beginning of the manual calibration operation, it is therefore necessary to ensure that the reservoir is well empty. Otherwise, the super consumptions and the floods carried out under the fuel level then observed, will not be detected or will be false. You must also wait for the sensor output signal to stabilize.
[0148] [000148] Then, for example, the reservoir can be filled to approximately 1/16. Thus, for a 1200 liter tank, 75 liters of fuel will be placed in the tank. The SC output signal from the sensor is then captured and a data point is added to the calibration file. Naturally, it is necessary to wait for the sensor's output signal to stabilize before capturing. This may take a minute or slightly longer after you have finished adding fuel to the tank.
[0149] [000149] Then, another point is made at 2/16 of the reservoir filling. This operation is performed until the reservoir is full.
[0150] [000150] In the example given, the reservoir is filled by 1/16. However, divisions of the reservoir volume in fractions ranging from 1/12 to 1/20 are entirely considerable to ensure the reliability of the monitoring system calibration. The intermediate values are then calculated automatically by box 10, typically by linear approximation.
[0151] [000151] With the sensor of figure 5, the position of float 143 corresponds to a measure of resistance on a potentiometer or ohmmeter 145 placed under the path of the lever arm 142 in the vicinity of the axis 145 of the sensor. The resistance value of potentiometer 145 is then variable depending on the position of lever arm 142 which is due to the buoyancy of float 143 at the level of the fuel surface.
[0152] [000152] Typically, the position of the float is then marked as a function of the value coming out of pot 145 over a number of positions in the order of a hundred and preferably around 65 positions.
[0153] [000153] The sensors used with the system will advantageously have a resistance that can vary between two extreme values, previously known, from the full reservoir to the empty reservoir.
[0154] [000154] These extreme resistance values correspond to the extreme positions of float 143 respectively for a full reservoir and an empty reservoir. For example, these values will range from 33 to 245 ohms or from 0 to 180, 33 ohms or 0 ohms corresponding to the empty or full reservoir and 245 and 180 corresponding to the full or empty reservoir.
[0155] [000155] These resistance values of float 143 correspond to ranges of digital values ranging, for example, from 19,700 to 48., 700 respectively for a full tank and an empty tank.
[0156] [000156] The invention therefore uses a voltage from the level 14 sensor circuit. This voltage varies depending on the resistance which itself varies depending on the height of the fuel level and, with the type of sensor in figure 5, the float position. The voltage that is an analog data is transformed into a digital data that is advantageously an index whose row goes, for example, from 0 to 65,535.
[0157] [000157] When the manual calibration process is carried out, for each calibration step, a total volume in liters present in the reservoir is associated with the digital index. An analog value is then transformed, which is a voltage at the sensor output into a digital value that is associated with a “liters in reservoir” value.
[0158] [000158] A number of lines equal to 10 being a minimum, preferably, the number of lines in the calibration file will be comprised between 16 and 20 lines. Typically, if the maximum capacity of the reservoir is 460 liters and if a file of 20 lines is required, it will be necessary to fill the reservoir by parts of approximately 23 liters.
[0159] [000159] The liters in the reservoir between two consecutive calibration points are automatically calculated pro rata. For a tank that has a height of 60 centimeters and a capacity of 600 liters, a 20-line calibration file allows for a real calibration of the fuel level in the tank every 3 centimeters, from 0 to 60 centimeters. It is observed here that, for a 600 liter paved tank, each 3 centimeters corresponds to 30 liters of fuel. Intermediate positions are calculated pro rata.
[0160] [000160] In figure 6, parts of 20 liters are used to perform the calibration file.
[0161] [000161] It is noted in the case that if a rod of origin previously installed on a reservoir is used for the application of the invention, a previous manual calibration is necessary in the manner presented above. A dedicated interface will then be advantageously used.
[0162] [000162] Figure 7 shows a flow chart of the method, according to the invention. This method is used mainly in the control box 10, but also partially in the middle of the control instrument 20.
[0163] [000163] First of all, the supply of the box 10 is permanently ensured thanks to a number of steps circuited on them, allowing, permanently, to ensure the supply of the box 10, either by battery 13 or by battery 15 depending on the state of engine 11.
[0164] [000164] Thus, in figure 7, in step EA1, the operation of motor 11 is examined. In case the motor 11 is running (case O), the battery 13 is energized. In this case, the battery 13 is selected by the connector with oscillation 102, in the middle of a step EA2, to feed the box 10 in a step EA4.
[0165] [000165] In the case where the motor 11 is not running, in an EA3 step, the battery 15 is selected by the oscillating connector 102 to supply the box 10 in an EA4 step.
[0166] [000166] It is noted in the case that the operation of the motor 11 is examined to allow the oscillating connector 102 to choose between the two supply modes. However, it is entirely considerable to use a contact switch position sensor instead of an engine 11 operating sensor, typically a voltage sensor installed on the alternator excitation terminal. In effect, generally, since the contact switch is in the “ON” position, the electrical supply circuit is energized and is therefore supplying the box 10.
[0167] [000167] Then, the method, according to the invention, questions the clock 103, in an EM1 step, in order to know an appropriate sampling instant in which the various data that constitute a data line in the periodicity will be captured chosen and pre-programmed, in this case 90 seconds.
[0168] [000168] The D / H date and time are then used to associate, in an EM2 step, an acquisition at the appropriate time of the SC 14 sensor output signal. Finally, in an EM3 step, the geolocation data Loc at the instant D / H are purchased from the geolocation receiver 105.
[0169] [000169] Then, in an EM4 step, the set of data Loc, SC, D / H is stored in memory in the form of an Ld / h line. The memory implemented in the middle of the box 10 will advantageously have a capacity of around 20,000 lines, 24,000, for example, which corresponds to approximately 20 consecutive days.
[0170] [000170] The successive Ld / h and Ld / h + 90n lines for N going from 1 to a predefined number, for example, 10, are then examined in the middle of an EM5 step to detect a drop in fuel level or an increase level of fuel in a constant geographical position.
[0171] [000171] In the event that a drop in fuel level is observed in a constant geographical position in step EM5, an AL alarm is then sent to the control instrument 20 that receives it, registers it and proceeds advantageously to a display of that alert AL in one step FM2.
[0172] [000172] In parallel, control instrument 2 is connected to or connected to box 10 in an FM0 step. Then, in an FM1 step, the Ld / h lines are transferred in deferred or real time to the control instrument 20 where they are stored in memory.
[0173] [000173] The control instrument 20 then allows the elaboration of several result tables of the type shown in figure 8. In this table, the characteristics of the observed consumption are presented for a plurality of vehicles operated in the middle of different exploration locations and driven by different drivers. In this case, it is observed that the identity of the driver who drove the vehicle over which the box 10 is loaded is generally an external data acquired in the middle of the control instrument 20 by data taking, thanks to the user interface 23. It is also the case for other data relating to the operation of vehicles, in particular an activity area, for example, to perform virtual protection ("geofencing", in English).
[0174] [000174] Regarding the driver's identity, the information can be retrieved by the embedded system when it is connected to the vehicle's chrono tachograph.
[0175] [000175] With reference to virtual protection, the data, provided it is previously informed by the user, can be automatically detected in real time by the embedded system. For example, the device can automatically control whether the GPS position at the time of detecting a flood corresponds to the location of a gas pump. This corresponds to a combination of information.
[0176] [000176] This on-board table allows you to monitor consumption more or less detailed depending on the driver, depending on the location of exploration or even depending on the vehicle.
[0177] [000177] Then it is possible to establish consumption averages and also to establish statistics on the environmental impact of the exploration, notably by calculating the actual CO2 emissions resulting from the exploration.
[0178] [000178] Advantageously, it has been seen that the control instrument 20 comprises a user interface 23 to acquire external data provided by a user of the control instrument 20.
[0179] [000179] Typically, this control instrument 20 will then be advantageously informed about the quantity of fuel introduced in each reservoir, depending on the fuel bills.
[0180] [000180] Comparing the quantity of fuel thus captured with an increase in fuel corresponding to the time and date of filling corresponding to the invoice, it is possible, thanks to the invention, to compare the quantities of fuel automatically in the middle of the control instrument 20 .
[0181] [000181] In this case, the control instrument 20 will be able, automatically and autonomously, to provide an alert to signal an inconsistency between the two quantities, if applicable. A robbery in the vat will then be suspected.
[0182] [000182] In addition, as the control instrument 20 has the LD / H data lines, such as received and stored in the middle of the control instrument, it is possible to perform a certain number of calculations, the ratios of which are the motor on time with the vehicle stopped, and the engine running time with the vehicle in motion. These reasons give access to a percentage of consumption that can be saved. However, the invention makes it possible to know the location, date and time of overconsumption due to an engine running with the vehicle stopped. This makes it possible to correct drivers' behavior and reduce overconsumption due to maintenance of the engine running at the stop.
[0183] [000183] It is also possible to make any type of statistical calculations, such as average consumption at 100 km, volume consumption, average consumption at the time the engine is started.
[0184] [000184] It is also possible to exclude or include the stolen fuel parts, since the invention allows to identify and quantify them, to calculate the real cost of the fuel station in the middle of an exploration or to calculate the real impact on emissions carbon in the farm.
[0185] [000185] It is observed that in this case the device may have an additional work function to the operation of its motor, requiring the operation of the motor to be activated. The box then comprises means for determining the operating status of that additional work function, the operating status data of the motor being included in the data line to be processed by the data processing module. The times during which the work function is activated are then excluded from the motor running times of the vehicle at the unproductive stop. The knowledge of the working status of the work function is typically to determine, from the activation or not of a power outlet carried by the device.
[0186] [000186] The control instrument 20 also makes it possible to gather data by group. For example, the set of vehicles operated on a site may be grouped in order to calculate the average consumption of the site and be able to compare the holdings in different locations. Comparisons between trucks can also be made or comparisons between drivers.
[0187] [000187] The control instrument 20, according to the invention, in combination with the box shipped 10, according to the invention, therefore allows to report on the past of a farm as well as to report on the current farm, this it is, in the present of the exploration, since it makes it possible to issue alerts in real time for the control instrument 20. In fact, according to the invention, it is considered that the control instrument 20 is connected via non-filar to the embedded box 10 so that, for example, the box 10 can transmit AL alerts in real time to the control instrument 20.
[0188] [000188] On the contrary, it is also desirable that the embedded box 10 can be connected via wire to the control instrument 20 to make the transfer of the data lines. In fact, a filar track is more adapted to the amount of data then transferred from box 10 to the control instrument 20. For example, an RS232 connection can be used.
[0189] [000189] In addition, it can be considered to ensure communications between box 10 and password control instrument 20.
[0190] [000190] It is also considered to pre-program the electronic monitoring system, so that it detects possible manipulations on the embedded box 10 in order to prevent its operation: disconnection of a sensor, etc. A specific alarm, preferably sent in real time to the control instrument 20, is then advantageously associated with this detection. Means to prevent piracy of the boxes shipped are known to the technician and can be implemented in the middle of the electronic system, according to the invention.
[0191] [000191] The control instrument 20 will also be advantageously capable of displaying, on its display device, maps showing the vehicle's path, as well as the locations of the reservoir fillings and, eventually, the places in which a drop in the fuel level was observed.
[0192] [000192] The invention makes it possible to have an accurate detailed view of fuel consumption and thus reduce irregular and unproductive consumption. The invention therefore makes it possible to globally reduce fuel consumption and reinforce the profitability and competitiveness of companies. In addition, the invention allows for better overall management for the installation of various accompanying onboard tables.
[0193] [000193] Engagements in structuring operations can be made by road transport companies, thanks to the invention and thus generate an additional source of mobilization and motivation for all staff.
