    description
    [0001] The present invention relates mainly to a method of communicating at least one information between a first control unit embedded in a first vehicle and a public transport network.
    [0002] Currently, the communication methods between equipment shipped in a first vehicle (of public transport type: train or its units, subway, tram, trolley, bus, etc.) and a physical public transport network (equipment on the ground and embedded in other vehicles) have consequent performances, which allow, in particular, to generate fast and safe commands as under the CBTC (Communication Based Train Control) technique, well adapted to self-guided / self-driving vehicles (for example, without a driver). For this purpose, control units are mainly arranged in infrastructures on the ground, in order to be able to issue information in the form of commands to vehicles or other equipment on the ground, such as changing needles or traffic signs on the ground.
    [0003] According to this logic, at the initial design stage as an update / renovation of a public transport infrastructure, it is therefore necessary to centralize control information on the ground in at least one central checkpoint (or several control centers) which must in any case be in communication), but it is also necessary to distribute (or redistribute) the information issued from these control units on the ground about the completeness of the public transport network to reach the receiving modules (if the issuing case) of each vehicle or ground equipment. This type of construction site is complex, since it involves multiple and expensive work operations (cleaning service installations for connected connections, installations of wireless radio points, such as "access points" distributed along the roads and forming a network soil, etc.).
    [0004] One purpose of the present invention is to propose a method of communicating at least one information between a first control unit loaded in a first vehicle and a public transport network (including equipment on the ground and loaded on any other vehicle) with the purpose of minimizing the complexity of this public transport network, both in terms of physical infrastructure (cleaning service facilities, cabling), as well as its communication aspect (filar equipment, technical locations).
    [0005] Using a method of communicating at least one information between a first control unit embedded in a first vehicle and a public transport network, the invention provides that: - the information is issued by the first control unit under the in the form of a command, that command being transferred to a first communication unit embedded in the first vehicle; - the first communication unit establishes a transmission connection, outside the vehicle with a second communication unit connected to an execution module of that command, the second communication unit and the execution module being arranged on the ground, or loaded in a second vehicle comprising a second control unit; - in the case of a transmission towards the second ground communication unit, the ground execution module is controlled under a slave mode directly governed by this command by a master mode of the first control unit. Then, ideally if not detectable autonomously by the first control unit, a confirmation of the execution status of the ground execution module is transmitted back to the first control unit, these round-trip transmissions being free of traffic via a communication infrastructure. in the soil; - in the case of a transmission towards the second embedded communication unit, the execution module embedded in the second vehicle is controlled under a slave mode directly governed, to let it execute under a master mode of the first control unit (CU1) thus placing, at least provisionally, a second control unit embedded in the second vehicle under a slave mode for the execution of this command. Then, ideally, a confirmation of the execution status of the embedded execution module is transmitted to the first control unit, these round-trip transmissions being free of traffic via a ground communication infrastructure. It is also considerable that the execution of this command is possible directly by controlling the second vehicle, since the slave mode of the second control unit is finally (re) switched in master mode to execute this command autonomously. Alternatively, (in particular, in case of an invalidation failure in the first vehicle or its control unit), if this confirmation implies a degraded mode between the control units of the first and second vehicles, an execution module (EXE1) embedded in the the first vehicle is controlled under a slave recommanded mode directly governed by a master mode of the second control unit, thus placing the first control unit at least provisionally, if (CU1) is loaded into the first vehicle under a slave mode to execute that command there. This alternation of the master / slave modes of the two control units continues until the initial command is failed under conditions that are at least safe.
    [0006] More particularly, the initially master mode of the first embedded control unit is allowed, thanks to a so-called "intelligent" pre-disposition, due to the fact that as much information and management processes as possible for a public transport network have been stored in this unit prior to the operation of this network (and by extension in all control units shipped in all vehicles). In other words and contrary to the state of the art in which this information and associated control processes with an "intelligent" character are mostly located on "master" equipment for managing the network / traffic on the ground and relaying it to the on-board and on-ground equipment, the method, according to the present invention, relocates the "master" function towards the on-board control units thus allowing these units to directly govern other equipment on the ground or on board, being free to request information flow via the equipment management network on the ground. The advantageous consequence of this use of the method, according to the invention, is mainly when an installation or an upgrade (extension or replacement of a railway network), all the complex operations of disposal of a ground control installation for management traffic are preventable or at least greatly simplified. The construction costs generated are, therefore, very low and the environment is preserved, as it must not be modified to implement control equipment or deploy a communication network throughout the cleaning service facilities.
    [0007] In particular, the method, according to the invention, provides that, in the case of a transmission towards the second communication unit on the ground, the command emanating directly from the first embedded control unit governs at least one of the following actions advantageous: - an opening of platform bearing doors, ideally, synchronously with the vehicle's bearing doors; thus, any risk of desynchronization between control modules of two automata (on board and with platform) for opening / closing the two bearing door systems is avoided. - a coupling and movement of needles is directly possible under the intervention of one or more approximate vehicle master modes, without having to obtain an authorization command from traffic management equipment or coupling generated on the ground; - a luminous or mechanical signaling on the ground is also controllable under the master regime of an embedded control unit, knowing that the control unit has the "intelligent" information previously stored in a safe manner; even in the case of a plurality of vehicles, each of its control units is able to self-regulate by establishing a hierarchy first master, second master as sub-master and slave, for example, for three vehicles in the vicinity of this signaling. According to this scheme, it is also possible to cyclically shift this hierarchy between the three vehicles to estimate that it is more adapted (certainly the most economical or faster in terms of the required traffic management), in order to optimally command the signaling; - a storage of instant information in a communication terminal on the ground transmitted by the first vehicle, the information being, ideally, readable by any vehicle that approaches it; thus, traffic data exchanges between distant vehicles are made possible more easily, without intermediary of network points on the complex ground; - a diagnostic issue to request a service on the ground, such as an energy supply, a maintenance step, an emergency; this emission can occur at the level of a communication terminal that centralizes this diagnosis, for example, at the level of a station that comprises an energy storage unit that, directly requested under the vehicle's master mode, charges the vehicle, according to its needs autonomy and those required by the rest of the public transport network; - a warning signal emission; this alert can thus be communicated, imposing other control units on the ground and onboard (mobile) in preventive "slave" modes to circumvent even reabsorbing the alert, according to safe vehicle control schemes; - a statement of functional status of equipment on board and / or on the ground; etc.
    [0008] The method, according to the invention, also provides that, in the case of a transmission towards the second embedded communication unit, the command emanating directly from the first control unit that governs at least one of the following actions: - one exchange of information such as CBTC (communication based trains control), ATC (automatic train control), IXL (interlocking), ATP (automatic train protection), ATO (automatic train operation), in particular adapted for self-guided vehicles; - an exchange of information that allows a pilot on board the first vehicle or a driver to drive automatically or manually the second vehicle; - an autonomous movement authority for the first and second vehicles; - a preventive anti-collision password, for example, switching master / slave modes from two control units in direct communication, or at least one control unit generally controlled by an anti-collision device (distance sensor, safe eye camera), etc.). - a vehicle boarding and mooring password, following the same principle as the anti-collision password; - an inter-vehicle emission of information from each vehicle according to various parameters, such as position, speed, energy levels, braking capacity, instant and predicted routes; this information in particular allowing each embedded control unit to prioritize master or slave modes according to the objectives and needs of each vehicle; - a forced protection switching of the master mode with slave mode of one of the control units or any other anomaly detected outside the safety standards, another of the control units can then freeze under a master mode in order to supply or compensate for the anomaly, for example, remote control equipment embedded in the vehicle including the control unit in slave mode; - a forced protection switching in master mode with slave mode of one of the control units or any other anomaly detected outside the safety norms, and remote control of the equipment embedded in the vehicle comprising the control unit in slave mode from a command ground network;
    [0009] The method, according to the invention, also provides that at least one of the vehicles authorizes a switching of a control unit on the ground under a master mode, in order to transmit the parameters connected to the network to an embedded control unit. , resources, planning and public transport equipment. This procedure allows to update and complete, in a central and simple way, the data with an "intelligent" character, from a single solo interface towards the vehicles, even to other equipment on the ground through vehicles that must approach them and them. transmit this data in a slave mode of the equipment on the ground imposed by a master mode of the vehicle control unit. Thus, the information is, in this case, advantageously transmitted in a mobile way, through the embedded control unit without resorting to a complex / costly communication network.
    [00010] The method, according to the invention, is particularly well adapted for the use of radio type connections applied to such information communications between the equipment of the first vehicle and the equipment on the ground or shipped outside the first vehicle. As a result, connections with cabling, pillars or by contact are non-existent, even for a connection between station equipment (for example, bearing doors) and those of vehicles.
    [00011] Finally, an application of the method, according to the invention, is particularly of greater interest, when implementing an update or putting into service of a physical public transport network and an associated communication network, in particular, maximizing, in a first phase, an initial supply of storable data in the control units shipped by vehicles in order, in a second phase, to minimize even eliminating the number of means of data transmission, information and commands, starting from of the communication infrastructures on the ground for these vehicles, this data thus stored and shipped being used to generate the information in the form of command. In other words, a public transport network does not need more than two levels of communication network on the ground and the network is carried along the cleaning service facilities, but only a network to allow inter-vehicle communication as well as for equipment on the ground. In other terms and according to a preferred mode of the invention, the use of the method, according to the invention, the use can be made being at least under a safe regime verified from the on-board equipment exempt from transmitting data, information and commands afterwards communication infrastructures on the ground towards this embedded equipment.
    [00012] Finally, the use of the method, according to the invention, provides that the data used to generate the information in the form of targeted command, in an identical and complementary way to the stored and embedded data, will be provided by the embedded sensory equipment, such as an optical sensor, a camera, a distance measurement sensor, an RFID reader and any other detector. Through this, one or more vehicles are made increasingly more autonomous (s) and oscillations between master / slave modes are generated under increased secure priorities, having reduced the complexity of communicating information to the "intelligent" and embedded network.
    [00013] Examples of realization and application are provided with the aid of the figures described:
    [00014] Figure 1: command of the switching needle of a signal from a terminal according to the method, according to the invention.
    [00015] Figure 2: command of a changing needle and a signal and the approach of two vehicles according to the method, according to the invention.
    [00016] Figure 3: control of vehicle and platform doors at the station, according to the method, according to the invention.
    [00017] Figure 4: anti-collision command between two vehicles, according to the method, according to the invention.
    [00018] Figure 1 shows a typical use of commanding an F 'signal and a switching needle A to engage, so that a V1 vehicle (train unit) can pass the signal and change its initial route VO1 for a second route VO2, after engagement and movement of the switching needle in the required position. The vehicle comprises embedded equipment, comprising at least one CU1 control unit that can send information in the form of a T2W command, this command being transferred from the control unit via a first embedded l / O_1 communication unit, in the case of radio type R1, to a second communication unit l / O_2, in this case also radio type R2, connected respectively to an execution module EXE_F, EXE_F executing the command received to control the signal and the switching needle. The method, according to the invention, provides in the case that the command connection between the on-board equipment and the two ground execution modules is free of any communication link with other ground communication equipment, since the execution modules on the ground solo are directly controlled under a slave mode governed by a master mode of the first control unit (CU1). In effect, the master mode of the first control unit (CU1) itself obeys a secure traffic management protocol such as those imposed in the past by a central control post on the ground, generated by routines and public transport operators.
    [00019] In the example of figure 1, another execution module of a railway terminal B can thus be autonomously generated by a second control unit CU1 "and its communication unit l / 0_1", all two being shipped. The control unit arranged in effect, from a direct knowledge of its speed (with the aid of a tachymeter, an odometer measurement or another means of measurement) and can thus release the vehicle information terminal, such as speed , vehicle identification, diagnosis, energy status, circulation plan, etc., in order to redistribute them to a next vehicle that will cross terminal B. This assumes that the connection between the many communication unit l / O_1 "and Terminal B is bilateral and the terminal must be placed under two slave modes of the recorder type of information emitted by the control unit and of the emitter type for reading the stored information.Therefore, several trains can, in redundancy with their individual plan of default traffic, autonomously recalibrate over global traffic management variations. In this case, this punctual management by terminals fixed on the ground is thus free from any communication network on the communication ground, extending from the cleaning service facilities and centrally controlled by a command post.
    [00020] According to these various configurations, other units or control routines, from other possible adapted communication units can thus be loaded on board the vehicles, thus allowing, according to this method, according to the invention, to be simply evolutionary in functions of the waits and progress of autonomous traffic management equipment.
    [00021] Figure 2 shows a case of a control of a switching needle A and a signal F in the approach of two vehicles V1, V2 to which the method, according to the invention, can be applied easily and very advantageously. Mainly, the first vehicle V1, the switching needle A and the signal F have the same characteristics as those of figure 1. The second vehicle V2 also includes, on the example of the first vehicle V1, embedded equipment, such as a unit control unit CU3 connected to a communication unit, as well as an execution unit EXE3 (symbolized by an arrow indicating the floor and direction of that vehicle.
    [00022] Thus, to illustrate this example, it is assumed that the first vehicle V1 travels towards the right on its first track V01 and the second vehicle V2 arrives from the left on track V02 distinct from the first track V01 and comprising the signal and the switching needle. Vehicle V2 then wishes to move from its second track V02 to the first track V01 by means of a part of track V012 that can be traversed, subject to the good command of the F signal and the switching needle A.
    [00023] A priori, according to this scheme, an application of the method, according to the invention, can be ideally considered, in order to avoid any collision between the two vehicles and, in particular, minimizing reaction times in the signal commands, the changing needle of the crossing of trains.
    [00024] The first vehicle is supposed to be a priority type over the second V2 vehicle, since, in a sufficiently safe approaching crossing zone, that second vehicle must leave its lane to go over another one. Also, the signal is of a priority type over the switching needle.
    [00025] In other words, when the first V1 vehicle passes through the crossing zone, it oscillates in the master mode, in order to control the F signal in slave mode (traffic stop imposed). The second vehicle V2 arrives towards the signal and must therefore respect it, so much so that the first priority type V1 vehicle imposes its master mode on the F signal, even if the second vehicle has already imposed its master mode on the needle. change of track A thus in slave mode. Once the first V1 vehicle has passed its V01 lane with the intermediate crossing V012, it then inhibits its master mode on the F signal that oscillates in the crossing authorization of that signal. The second vehicle V2 can thus pass over the intermediate crossing path V012. Eventually, a third application of the method, according to the invention, can also intervene due to the fact that the first vehicle V1 oscillates under a master mode in connection with a slave mode of the second vehicle, in order to prevent it from running any EXE3 order. , when the first vehicle V1 has not entirely crossed the intersection of its V01 and intermediate V012. This last application of the method, according to the invention, is, of course, redundant, but it can thus, in case of signal failure, ensure the crossing of vehicles from any collision.
    [00026] All of these described steps follow two or three grouped applications of the method, according to the invention, and therefore took place without the intervention of a command or authorization from a central command post on the ground or management equipment located in technical locations. Only local equipment on board and on the ground governed a train crossing with a safe change of track.
    [00027] Another case of the figure can be, if the first vehicle is stopped before, after passing the junction of its V01 and intermediate V012 and it shows that its control unit or at least its command in master mode over the F signal in slave mode has an anomaly and permanently blocks the signal in the no-crossing position for the second vehicle, which blocks the signal on the switching needle safely also the switching needle A in a closed position (the second V2 vehicle being forced to remain on its V02 track). The second V2 vehicle that detects the presence and a diagnosable anomaly of the first V1 vehicle that is a priority, and therefore a master in the sense of an EXE3 driving command, then uses a feedback transmission of the driving command, then its control unit CU3 towards the first vehicle V1 and forces it to oscillate from its master mode to a slave mode, forcing its execution module EXE1 to circulate on the first track V01 at least to ensure that it should have crossed the junction and, therefore, release the passage of the second vehicle V2 over the first track V1. In addition, the second vehicle, having resumed the master mode initially agreed upon with the first vehicle, also sends a command to change the status of the blocked F signal to authorize its crossing and, finally, to unlock the switching needle. The second vehicle is, therefore, provisionally made master in the sense of several command modes compared to the equipment loaded on the first vehicle V1 and on the ground A, F.
    [00028] In the case still, a situation of crossing balanced by an anomaly of a vehicle allows itself to be governed without the need of means of communication on the ground supplementary to those of the embedded equipment and of signaling / orientation of the vehicles in the sun.
    [00029] Figure 3 shows an advantageous application of application of the method, according to the invention, in the case of the control by a vehicle V1 arriving at a station platform Q, the vehicle and the platform comprising respectively a set of bearing doors that the opening and closing mechanisms must respect a precise and safe spatial and temporal scheme for passengers. In this example, this control unit CU1 of the vehicle V1 on the platform which, by transmitting T2Q command information, will impose its master mode on any execution module in slave mode such as the opening automaton of each of the two sets of doors with bearings (shipped and on the platform). In this way, an opening / closing time out of synchronization and an alignment error of the opening edges of the door sets with bearings are advantageously avoided. Thus, the automaton for opening the set of bearing doors with platform P2 can be subjected to that of the set of doors with embedded bearings P1. Likewise, the signal that initiates the opening of the two sets of doors with bearings can also be released by the only embedded control unit CU1, after it has received (from a final approach execution module on the platform, also commanded under a mode slave), a tolerated relative positioning signal of the vehicle in relation to the platform. In other words, no command source of an "intelligent" character is placed on the platform, but has been integrated into the embedded equipment.
    [00030] Figure 4 shows an advantageous application of anti-collision control between two vehicles V1, V2 on the same track according to the method, according to the invention. The same idea can be deduced for an approach, a mooring or a division of vehicle (train) units. In this case, the control unit CU1 of the first vehicle V1 transmits radio control information T2T in master mode directly to a progress execution module of the second vehicle V2 in slave mode to inhibit or attract an order of progress to approach the first vehicle. vehicle in the event of a mooring, after receiving from another execution unit "SafeEye" (such as an inter-vehicle distance pickup) in slave command mode and an approach or stop authorization is loaded on the first V1 vehicle. Alternatively or in addition, the master / slave modes can be periodically inverted in order to ensure a doubly safe development of a mooring procedure, for example. Thus, an anti-collision control between vehicles or trains can be permanently ensured in an autonomous and simple way, without the need for external control on the ground by a central post in connection with the entire physical public transport network.
    [00031] Finally, a preferred application of the method, according to the invention, provides that the communication units of the various embedded equipment and the ground are provided with radio modules under modes of transmission of signals free from interference and ideally allowing an instant identification of two pieces of equipment in a defined perimeter. In this way, the communication of information between different equipment can be more selective, fast and permanently updated according to a list of pairs of equipment that can be associated under master / slave modes and classified under variable priorities of an autonomous safe traffic scheme.
