    The invention relates to a device and method for capturing and recording fine particles and / or the density of NOx gases in the air. air, in particular for the capture and recording of fine particles and / or the density of NOx gases in the air, in particular in a mobile manner and in various parts of an urban city.
    It is known that the vehicles with thermal engine, numerous in the urban cities, contribute to pollute strongly these cities by the polluting gas emissions of their engine and the emitted dusts, in particular the fine particles with very fine, and the dusts resulting from the braking and of vehicle rolling. These polluting discharges and dusts are harmful to the health of the people who are subjected to them, in particular the very fine particles of diameter less than 2.5 micrometers, called PM 2.5, which enter the respiratory tree and can even penetrate the systemic blood network, thus participating in the durable installation of derogatory health problems, likely to result in cardiovascular complications or the appearance of cancers under different expressions.
    It is particularly useful to know the rate of these particles in places exposed to a high density of fine particles to modulate or adapt its activity (especially physical activity and movement) according to this density and thus preserve its health.
    Moreover, for people with fragile bronchi (asthma-prone in particular), it is useful to know in parallel particles deleterious gases present in the air, including so-called nitrogen oxides NOx. The invention aims to remedy all or part of these ailments.
    It is proposed according to the invention a device for capturing and recording fine particles and / or density of NOx gas in the air, characterized in that it comprises at least one particle sensor and / or the the density of the NOx gases in the air, able to count a number of particles or dust present in the air, of dimension comprised between determined values in a volume of air, and / or the density of the NOx gases and a means of displaying and / or recording said number and / or density in correlation at a determined measurement point of the sensor, the device being further configured to be embedded and operate on board a vehicle (including any mobile support).
    The device may also comprise, as mentioned above, a NOx gas sensor capable of measuring a density of NOx gas in the air and means for displaying and / or recording said density in correlation with a determined location of measurement of the sensor.
    Said numbers of particles and density can then, alone or together, be measured, displayed and recorded (on databases) in correlation with a determined location of measurement including a measuring circuit of the vehicle.
    Said values are in particular less than 2.5 micrometers and correspond to the most deleterious particles for human health.
    The volume of air considered is the cubic meter. A number of fine particles per cubic meter of air is thus counted.
    Said display and / or recording means may comprise a simple screen for displaying said number and / or said density, or a device for capturing said number and / or said density, on a recording medium, such as than a printer on paper or a data file.
    Said display or recording is advantageously carried out on a support corresponding to a geographical map of said determined location of measurement.
    It is thus possible to determine discontinuously or continuously during the rolling of the vehicle a mapping of the density of fine particles and / or said density of NOx gas in the air of said place. This information can be transmitted in real time or deferred to at least one database that can be exploited through various applications, including relating to the management of the movements and activities of people in the area appreciated for the preservation of health .
    Said discontinuous manner of determining the capture of particles and / or said density of NOx gases can be established at particular points to be measured of said location, for example sensitive areas of a given geographical area of the place, each point being affected by a measurement of the number of particles and / or the density of the NOx gases, for example the number of fine particles per cubic meter.
    The measurement can be carried out at a standstill or when the vehicle is rolling. The stop can be delayed according to a determined period of time to enable the resetting or recalibration of the sensor at each measuring point, for example by means of a fixed terminal of fine measurement in a stabilized environment, and thus making reliable the measurement of each point without the sensor is not influenced by the measurement air from the previous point. Measuring the particles and / or the density of the NOx gases according to said period is performed on a measurement circuit, from the vehicle, in said location.
    The bearing can also be operated at a moderate speed in the measuring circuit according to the sensor reset capability, for example less than 30 km / hour allowing the sensor to make a measurement on the fly (on the move) and with a margin acceptable error measuring the air surrounding the vehicle.
    Resetting or even recalibrating the sensor from fixed terminals makes it possible to ensure threshold values and thus to guarantee the values measured with an error margin of less than 0.2 or even up to 0.4 at the maximum.
    The particle sensor is preferably an optical dust sensor, for example of the type "GP2Y1010AU0F Sharp" designed to detect particles in the air and thus estimate the air quality. Such a sensor, of the detector type of a quantity of light passing through a volume of air, makes it possible to display an instantaneous value of the particles in the said spectrum of determined values, in particular less than 2.5 micrometers.
    The NOx gas sensor may be an optical sensor measuring a wavelength spectrum corresponding to the gases in the air.
    Such a sensor can be supplied with energy by an electrical source of the vehicle, or even by a battery recharged from the vehicle.
    Said sensor is advantageously mounted on the vehicle in a position conducive to the reception, preferably instantaneous, of the air to be measured for capturing the particles and / or said NOx gas density in the air of the point to be measured. The sensor is also configured to minimize the impact of air movement, wind and / or vehicle speed.
    The (random) movement of air on the sensor can be minimized by equipping it with a periphery protective skirt configured to let the rolling air, for example provided with a grid through which the air passes.
    In addition, the residual air of a given measurement point of the sensor is advantageously evacuated by a device for evacuating the residual air in the sensor, for example a device for blowing neutral air into the sensor, prior to each new measure. Such a device for evacuating the residual air is mounted on the sensor.
    The sensor may be mounted on a mat of the vehicle, or even a movable arm and telescopic, adjustable in orientation and / or height, in particular for a variable height measurement, for example according to a vertical projection line of the measuring point.
    The measurement can thus be made at several heights for a given point; it can also be performed in an environment of the given point, at a distance close to the point or the vertical point, for example by orienting the mat and the sensor to a given measurement height.
    It is thus possible to determine the density of particles and / or gas at height of stroller, height of passing on a sidewalk, ground floor or floor on a residential complex, or even inside the building. 'building.
    It is also possible to determine the impact of a polluting source, for example of a chimney or an air outlet mouth coming for example from underground public transport (such as metro or RER) "in its immediate environment.
    The mounting on a non-emitting vehicle particles (non-polluting, for example electric motor) allows in particular not to influence the measurement unlike a vehicle with a combustion engine. In the latter case, it is to isolate the sensor from the smoke source of the engine, including away from the latter, considering the wind and the movement of the vehicle relative to wind etc.
    The device is advantageously coupled to a device called GPS (Global Positioning System (GPS) in English) corresponding to a Global Positioning System or Geo-positioning Satellite.
    Thus the device can be configured to associate with a GPS location map localized punctual display, including real-time and dynamic density of particles and / or gas at one or more measurement heights. The map is then supplemented punctually with values of the said number of particles and / or the density of the NOx gases. The recording of values can be sequenced at a determined time between two consecutive measurement points, in a given advance of the vehicle corresponding to a given distance traveled so as to obtain a regular punctual display of said particle values and / or the density of the particles. NOx gas on the vehicle circuit.
    The sensor can also be initialized, or even calibrated again, at certain points of the card, with reference to standardized sensors, for example point and static PM 2.5 "Airparif" particle sensors.
    The device may comprise a housing preferably mounted on the vehicle dashboard, connected to said GPS device and the sensor, said housing being configured to display and / or record the GPS device data and the sensor data at each measured point.
    Possibly other data concerning air quality, such as humidity, cloudiness, electromagnetic waves, noise level in decibels etc. can be displayed. and / or saved. Preferably, the data entry is stored in memory for subsequent recording and in particular constitute a dynamic database.
    The housing may comprise a data display screen, in particular displaying a geographical map of the measurement site supplemented from time to point with said particle number values and / or the density of the NOx gases, which is convenient to follow the evolution live. of measure in space and time.
    Advantageously, said device is permanently mounted on the vehicle, for example on the air supply block of the engine or the passenger compartment (secure and non-vandalizable mounting), but it can be quickly removable on the vehicle in a vehicle. compact shape (without mat or measuring arm). Said sensor can be mounted on the windshield (in a discrete position), the roof or the hood of the vehicle, or any other bodywork or external element such as a mirror capable of receiving in good conditions of capture said sensor. . The invention also relates to a method for measuring and displaying and / or recording the particles and / or the density of NOx gases in the air by means of at least one particle sensor and / or the density of the gases. NOx in the air, capable of counting a number of particles of size between determined values in a volume of air and / or the density of the NOx gases, and by means of a display device and / or recording said number and / or density in correlation at a given location, the assembly being further configured to be embedded and operate on board a vehicle (including any mobile support, or even a drone), the method comprising an input of said number and / or density at points of a measuring circuit on board said vehicle.
    These and other features and advantages of the invention will emerge more clearly from the following description of embodiments of the invention with reference to the appended drawing, in which: FIG. 1 is a diagrammatic elevational view; of a device for capturing and recording fine particles in the air, mounted on a motor vehicle, seen from the passenger compartment of the latter, according to one embodiment of the invention, - Figure 2 is a view in schematic elevation of a particle sensor of this device, and - Figure 3 shows a device for recording data of the device, arranged at a distance from it and a printed geographical map of density of fine particles in the air in a given geographical area, obtained by the implementation of the device.
    In the following description, like reference numerals are used to denote similar or identical elements.
    With reference to the drawing, FIG. 1, there is illustrated a device 1 for capturing and recording fine particles in the air according to one embodiment of the invention mounted on a vehicle 2. This device here comprises at least one sensor 3 of particles in the air, capable of counting a number of particles or dust present in the air, preferably an optical sensor, for example of the "Sharp GP2Y1010AU0F" or other type, designed to detect the particles in a volume of air, usually a number of particles of a given dimension or less in a cubic meter of air. Here, it makes it possible to display an instantaneous value of the number of particles per cubic meter of air in a spectrum of determined dimension values fixed in the example at 2.5 micrometers and less (PM 2.5). These particles are indeed deleterious for the health of people, infiltrating deep into the respiratory tree, or even the blood network after passing through the wall of the alveoli lungs.
    The sensor is here disposed on the windshield 5 of the vehicle, discretely in a corner thereof, being secured thereto by a suitable fastening means, preferably removable, for example by contact jamming.
    The device may comprise several sensors of this type to provide more precise information on the quality of the air, for example two sensors each arranged at a corner of the windscreen, each operating a capture of particles of different dimensions, in particular 2.5 micrometers and less. and 10 microns and less per cubic meter of air.
    The device may also comprise, for example in replacement of the aforementioned sensor 10 micrometers and less per cubic meter of air, a sensor as specified before the density of NOx gases in the air.
    The device also comprises means for displaying and / or recording 7 said number of particles in correlation with a determined measuring point of the sensor, the device being further configured to be embedded and operate on board a vehicle, here a motor vehicle. This means comprises in the example a housing 9 mounted on the dashboard 11 of the vehicle, connected to a device 13 "GPS" (Global Positioning System (GPS) in English) and the sensor 3. The housing is configured to display and / or record GPS device and sensor data at each measured point.
    Preferably the data entry is stored in memory to be subsequently recorded or simultaneously by a transmission means, for example wireless 24, a mobile or integrated telephone support, etc., here by means of an information processing unit. such as a laptop 15 shown in Figure 3 and a recording or printing unit, for example a printer 17 connected to the computer. A map 18 of the GPS device data and that of the sensor at each measured point of the measurement circuit 20 is printed on paper. The legends circled on this circuit represent the values of the number of fine particles per cubic meter of air at each measured point. The information collected can also be recorded on a database 16 exploited elsewhere in the form of applications on mobile phone, tablet computer, computer, "GSM", "GPS" etc.
    The housing 9 here comprises a screen 19 for displaying the data, in particular displaying a geographical map of the measurement location (GPS map) supplemented punctually with said particle number values entered by the sensor, which is convenient for following live the data. evolution of the measure.
    It is thus possible to determine discontinuously or continuously during the rolling of the vehicle a map of the density of fine particles in the air of said place.
    Said discontinuous manner of determining the capture of the particles may be established at particular points to be measured in said place, for example sensitive places of a given geographical area of the place, each point being affected by a measurement of the number of particles, by example of the number of fine particles per cubic meter.
    The measurement can be carried out at a standstill or when the vehicle is rolling. The stop can be delayed over a period of time to allow the reset or recalibration of the sensor at each measurement point on a measuring circuit, from the vehicle, in said location.
    The bearing can also be operated at a moderate speed in the measuring circuit according to the sensor reset capability, for example less than 30 km / hour allowing the sensor to make a measurement on the fly (on the move) and with a margin acceptable error measuring the air surrounding the vehicle.
    The reset of the sensor makes it possible to ensure the threshold values and thus to guarantee the measured values according to a margin of error lower than 0.20 or even up to 0.40 at the maximum.
    Said sensor is advantageously mounted on the vehicle in a position conducive to good reception of the air to be measured for capturing the particles (and / or the density of the NOx gases) in the air of the point to be measured. Said sensor is here mounted on the windshield but it can be mounted on an engine air intake block or cockpit, on the roof or the hood of the vehicle or a mat or other arms and accessories attached to the vehicle.
    The sensor can thus be mounted on a mat of the vehicle, or even a mobile and telescopic arm, adjustable in orientation and / or height, in particular for a variable height measurement, for example according to a vertical projection line of the measuring point.
    The measurement can thus be made at several heights for a given point; it can also be performed in an environment of the given point, at a distance close to the point or the vertical point, for example by orienting the mat and the sensor to a given measurement height. It is thus possible to determine the density of particles (and / or the density of NOx gas in the case of a gas sensor) at height of stroller, height of the passers-by on the sidewalk, ground floor or floor or at the same time. interior of a residential complex.
    The sensor can also be configured to minimize the impact of the air movement, the wind and / or the speed of the vehicle, for example by equipping it with a periphery protective skirt configured to allow the rolling air to pass. , for example an external grid 21 traversed by the air as shown in FIG.
    In addition, the sensor may comprise a device for evacuating the residual air in the sensor, for example a device for blowing neutral air into the sensor (not shown), before each new measurement, which can accelerate the initialization of the sensor.
    Said values can still be initialized at certain points of the card, with reference to those corresponding to standardized particle sensors (of precise measurement), for example fixed "Airparif" fixed sensors arranged on the circuit. The invention also relates to a method for measuring and displaying and / or recording the particles and / or the density of NOx gases in the air by means of at least one particle sensor 3 and / or the density of the particles. NOx gas in the air, capable of counting a number of particles of size between determined values in a volume of air and / or the density of the NOx gases, and by means of a device 7, 15, 17 of display and / or recording of said number and / or density in correlation at a given location, the assembly being further configured to be embedded and operate on board a vehicle 2, the method comprising an input of said number and / or density at points of a measuring circuit on board said vehicle. The recording of values can be sequenced at a determined duration between two consecutive measurement points, in a given advance of the vehicle corresponding to a given distance traveled so as to obtain a regular point display of said particle values and / or NOx gas density. on the vehicle circuit.
    The operation of the device is simple. Device 1 is activated from the vehicle control panel. It is a question of maintaining the operation on the preset measuring circuit by following the evolution of the measurement displayed to possibly complete the circuit according to the relevance of the values read. A terminal registration is operated permanently by means of the home computer 15.
