    The invention relates to a system for securing at least one maintenance railway track on which a train can run and park, so that at least the driver of the train can be authorized in particular to leave the track and the operators authorized to intervene on the train in complete safety.
    PRIOR ART Maintenance centers for railway vehicles, such as passenger transport trains, have several tracks in parallel, sometimes several hundred meters long.
    Automatic lane management systems make it possible to manage access to such lanes.
    However, there is the problem of avoiding the departure of the train if people are intervening.
    They are not necessarily visible from the driver's cab, or even from the dock.
    It was suggested to use a mobile beacon manually and manipulated by the worker who places it on the platform or on the track and then removes it when he has finished the procedure.
    However, this is not very reliable, especially when several people are involved, possibly in a time-shifted manner.
    There are also procedures in which intervention information is centralized in a security post.
    Interventions are scheduled with a start and an end of the intervention.
    This does not allow flexibility in the time of the intervention, whether for a shorter or longer duration.
    This also does not make it possible to know who is working on the train or who has finished.
    There is therefore a need to secure maintenance interventions in such installations with greater flexibility and more detailed knowledge of the conditions of intervention.
    Disclosure of the invention With these objectives in view, the invention relates to a system for securing at least one maintenance railway track on which a train can run or park, characterized in that each track comprises at least one terminal main signaling displaying at least three states: - a first state indicating that the train is likely to run on the track; - a second state indicating that a maintenance intervention is authorized; - a third state indicating that a maintenance operation is in progress;
    the main terminal comprising an identifier support reader, the system further comprising a central server, a gateway and a control device, the terminal being in communication with the gateway via a digital wireless network, the gateway being in digital communication with the server, the control device being in digital communication with the server or the gateway, the system being programmed to: - issue an authorization to intervene with the control device and transmit it to the main terminal via the gateway and the network digital wireless, the terminal switching from the first state to the second state upon receipt of said authorization to intervene; - record the arrival or departure of a person using an identifier medium with the identifier medium reader, the system maintaining a list of people present on the track; - switch the display of the main terminal from the second state to the third state when at least one person is present, and switch from the third state to the second state when no person is present; - switch the display of the main terminal from the second state to the first state when the control device transmits an end of intervention. The system according to the invention makes it possible to secure the management of a maintenance center with at least one channel. It allows supervision by the work organization which authorizes the start of work on or in the train parked on the track and the departure of the train at the end of the work.
    It also allows each operator who intervenes to individually signal the start of the intervention and its end, which prohibits the departure of the train as long as an operator remains present. The means of the system are fixed and do not require the handling of objects on the part of the operators, apart from the identification medium, such as a badge, which can be light. The states of the main terminal are, for example, achieved by lighting lamps of different colors, in other words lights. The first state will be signaled by a green light, the second state by an orange light and the third state by a red light. The use of a wireless network makes it possible to equip without too much cost an existing installation to communicate between a supervision station and the main terminal, avoiding the installation of communication cables over long distances. The system makes it possible to know the overall status of the occupation of the tracks and of the interventions in progress, remotely and instantly. In addition, it allows fine management of intervention authorizations. This increases the level of security with greater ease of intervention. According to an improvement, each channel further comprises a secondary terminal, the main terminal and the secondary terminal being placed respectively at one and the other end of the channel, the secondary terminal duplicating the display of the states of the main terminal. This makes it easy for the driver to see the status displayed by either terminal, whether at one end or the other of the train. According to a constructive arrangement, the secondary terminal further comprises an identifier support reader and is programmed to transmit reading information from an identifier support to the main terminal of the same channel so that the main terminal records the arrival or departure of the person using said identifier medium. Thus, whether the operator enters or leaves the train at one end or the other, he has the means to signal his movement.
    According to an improvement, the control device is able to request the state displayed by the main terminal and to display it. Thus, a supervisor has a means of remotely knowing the status of all the channels.
    According to an improvement, the digital wireless network between the terminals and the gateway is a mesh network, each terminal and gateway being able to receive and relay frames.
    Advantageously, the digital wireless network can include at least one intermediate relay terminal between a main terminal and a secondary terminal. This relay terminal makes it possible, if necessary, to guarantee communication between the two terminals, depending on the distance between them, the technology used and the environment more or less favorable to wireless communication.
    According to an improvement, the main terminal and / or the secondary terminal comprises a manual input device configured to change the state indicated by said terminal in a derogatory mode. This provides a derogatory mode to compensate for a possible malfunction, for example when communication with the server is broken or the server is down.
    According to a constructive arrangement, the digital wireless network is formed of communication modules integrated into the terminals and gateway. Communication modules of the same design can be used for different elements of the system.
    According to a constructive arrangement, the main terminal or the secondary terminal further comprises a control module in connection with the communication module and with the identifier support reader, at least one fire module for displaying the states, the control module fire being controlled by the control module. The same structure can be used for the main terminal and the secondary terminal, the difference being that the main terminal is configured to receive intervention authorizations and request individual authorizations, and the secondary terminal to duplicate the status. from the main terminal. The communication module used alone makes it possible to form a relay terminal. According to an improvement, the main terminal or the secondary terminal further comprises a display module for displaying messages, in particular the number of people present and / or the name of the person associated with the identifier medium read. Any operator can thus know on the spot whether the train is free or not. According to an improvement, the main terminal checks that the identifier medium is authorized, registers the person if the identifier medium is authorized and issues an alert if it is not authorized. This provides a means of controlling the authorization of people to intervene. The main terminal, for example, queries the server which contains a list of authorized persons. The registration of the person is in this case carried out at the level of the server. In a variant, the main terminal contains rules which make it possible to issue an authorization.
    In addition, the authorization to intervene includes an indication of the mode of intervention, the persons being authorized to intervene or not depending on the mode of intervention. It is thus possible to choose from the control device groups of persons authorized to intervene and to apply the control accordingly.
    In particular, the list of people present is maintained by the server and the verification of the authorization of a person by the main terminal involves querying the server. Thus, the server can provide different people with the list of people working on all the channels. The server can also issue intervention authorizations according to established rules.
    According to an improvement, at least one of the main, secondary or relay terminals has a solar panel and battery power system. Such a terminal can thus be set up without requiring an electric power cable, which facilitates its installation. This principle can be generalized to all terminals, or only to terminals remote from an electrical network.
    Brief description of the figures The invention will be better understood and other features and advantages will become apparent on reading the description which follows, the description referring to the accompanying drawings, among which:
    [Fig.1]: Figure 1 is a schematic plan view of an installation in which the system according to the invention is deployed; [Fig.2]: Figure 2 is a schematic view of the system according to the invention; [Fig.3]: Figure 3 is a schematic view of the elements of a main terminal; 5 [Fig.4]: Figure 4 is a flowchart explaining the operation of the system.
    Detailed Description In an installation intended for the maintenance of train sets, as shown in Figure 1, maintenance railway tracks 1 are arranged parallel to each other, with platforms extending between the tracks.
    The installation also includes a building 2 in which there is a supervision room 20. The tracks 1 are designed to accommodate the movement and parking of trains, not shown, up to 500 m in length.
    Tracks 1 are at intervals of approximately 10 m.
    Each channel 1 has a main signaling terminal 3, at the far right end in Figure 1, a secondary terminal 4 at the far left end in Figure 1 and an intermediate relay terminal 5 between the main terminal 3 and the secondary terminal 4. The installation further comprises a digital wireless network gateway 6 arranged on the building 2 and in digital communication via the wireless network with at least one of the terminals 3, 4, 5. In Referring to figure 2, the main 3, secondary 4 and relay 5 terminals each have a communication module 30, shown in figure 3, which communicates with the other communication modules 30 so as to thus form a digital network without mesh wire.
    In fact, each terminal 3, 4, 5 and gateway 6 is able to receive and relay frames.
    One of the possible technologies for this mesh network is the "Bluetooth Mesh" technology defined by the "Mesh Profile" document dated July 13, 2017 by the "Bluetooth SIG" group. Alternatively, “Zigbee”, “WIREPAS” and “SMART MESH” technologies also offer mesh network training.
    Depending on the local configuration, in particular the distances between the main and secondary terminals 3, 4 and the characteristics of the communication modules 30, relay terminals 5 can be added or removed in order to guarantee the correct transmission of data.
    The main 3 and secondary 4 terminals are provided to display at least three states: - a first state indicating that the train on track 1 is authorized to run or that the track is free; - a second state indicating that a maintenance intervention is authorized; - a third state indicating that a maintenance operation is in progress. For this, as shown in Figure 3, each terminal 3, 4 includes a fire module 31 to display the states. The fire module 31 comprises at least three light panels oriented in four different directions and arranged at the top of the terminal. Each panel comprises light emitting diodes of three different colors associated respectively with the three states described above. For example, we will choose green for the first state, orange for the second state and red for the third state.
    The main 3 and secondary 4 terminals include an identifier support reader 32, for example an NFC (Near Field Communication) contactless reader. The identifier media 33 can be cards with an RFID tag or any other equivalent technology.
    Each main 3 or secondary 4 terminal further comprises: - a control module 34 in connection with the communication module 30 and with the identifier support reader 32, - a sound module 35 for emitting a sound in connection with the module control 34, - a manual input device 36 in connection with the control module 34 and configured to change the state indicated by the main terminal 3, - a display module 37 in connection with the control module 34 for displaying messages, and - a checkered panel 38 for giving a command to prevent a train from entering on track 1 when the checkered panel 38 is on.
    The fire module 31 is controlled by the control module 34. The terminals receive an electrical power supply, for example by the sector or by a power supply system 40 with photovoltaic solar panels 401 and batteries, and include a power supply module 39 to supply current at the voltage suitable for each module, such as for example the checkered panel 38, the display module 37, the sound module 35. The power supply module 39 can be integrated into one of the other modules such as control module 34 or communication module 30. Power module 39 can supply current to control module 34 and the latter deliver power to fire module 31 and checkered panel 38.
    The operation of the system is now described, in particular in connection with FIG. 4. We consider an initial situation 100 in which the main terminal 3 and the secondary terminal 4 of a channel 1 are in the first state and control the fire modules. 31 to display a green light. A list of people in intervention, maintained by the main terminal 3, is empty. The checkered panel 38 is off. A train can dock alongside track 1. In step 101, an installation manager, identified COPROD, handles the control device 8 and delivers, using the application therein. installed, an authorization to intervene to a channel 1 identified, for example by a number or a channel marker A. In step 102, the authorization is received by the server 7 which transforms it into the form of 'a message including the number of the main terminal 3 of said identified channel 1, the message being transmitted to the gateway 6 which broadcasts the message over the mesh network.
    By the specific technique of the mesh network, which is not detailed here, the communication module 30 of the main terminal 3 of the identified channel 1 receives the message and transmits it to the control module 34. The latter then controls the module. light 31 to display the second state, for example amber light. The control module 34 also sends a message to the secondary terminal 4 of the same channel 1 to also display the second state.
    One or more people then come to intervene on, under or in the train parked on track 1. For this, a first person presents, in step 103, an identifier support 33, also called a badge, to the support reader d 'identifier 32. The reader 32 reads an identifier which it transmits to the control module 34 to which it is connected. The control module 34 orders the communication module 30 to send a message to the server 7, via the gateway 6, and containing the identifier.
    The server 7 has a database with a user table. In step 104, it verifies in the users table that the identifier corresponds to a person registered and part of an authorized team. If this is the case, it sends the name of the user to the main terminal 3 with an authorization message. In step 106 (steps 105 and 107 relate to a second embodiment which will be described later), the control module 34 controls the display module 37 to display the identifier read and the name of the user, it controls the sound module 35 to emit a short sound and controls the fire module 31 to switch or remain in the third state, for example fixed red. It also requests the sending of a message to secondary terminal 4 to switch to this third state.
    The intervention can begin at step 108. The other persons also present their identifier medium 33 to the reader 32 at step 109. If the identifier is already recorded in the list of persons present, it is removed from the list. list and is considered to be starting. If it is not registered, it is considered to be an arrival and the identifier and the name of the person are added to the list stored by the server 7. If the person is not authorized in step 104, the server 7 transmits this information to the main terminal 3 and the control module 34 controls the checkered panel 38 to turn it on and the sound module 35 to emit a long or continuous alert, in step 117. The server 7 also transmits an alert message to the installation manager by the control device 8 in step 118. If a person presents his identifier support 33 while the terminal is in the first state, therefore from the initial situation 100, as shown in step 116, the control module 34 of the main terminal 3 triggers the same alert in step 117 and sends a message to the server 7 in step 118. The alert is maintained until the manager verifies or has verified the conditions for a return to service, in step 119.
    The operator who presented his identifier support 33 by mistake presents it again on the main 3 or secondary 4 terminal to signal his departure at step 120, so that he is removed from the list of people present on the way. If there are no more other people working on the track, in step 121, the end of the alert is generated in step 122 and the terminal is then returned to step 115 in the initial situation 100 .
    When an identifier medium 33 is presented to the reader of the secondary terminal 4, the control module 34 requests the communication module 30 to transmit the identifier read to the main terminal 3 of the same channel 1. The main terminal 3 receives the identifier and processes it in the same way as above. In a variant, the secondary terminal 4 directly sends the reading information from the identifier medium to the server 7 which processes this request as if the information came from the main terminal 3 associated with the secondary terminal 4.
    When after the processing of the reading of an identifier in step 109, the list of persons is empty, as shown in step 112, the control module 34 switches the state of the main terminal 3 to the second state, as shown in step 113. It thus controls the fire module 31 to display the second state and transmits this command to the secondary terminal 4 which also displays the second state. The main terminal also transmits the information of the new state to the server 7, which transmits the information to the control device 8.
    At this moment, the installation manager can give, with the control device 8, an end of intervention message to the main terminal 3 of channel A, in step 114. In response, the control module 34 of the main terminal 3 thus controls the fire module 31 to display the first state, as indicated in step 115, and transmits this command to the secondary terminal 4.
    At any time, the server 7 can send an either global or individual request to obtain the status of each of the channels 1. It then updates this status and makes it available to the control device 8 or to the mobile telephones 9a so that these display it either in continuous update, or at the request of the user. The server 7 can also control the display of the status of channels 1 on the display screens 9b placed on the site in order to have only the visualization of the status of each channel.
    At any time, the server 7 can send an either global or individual request to obtain the list of people held by each of the main terminals, and provide it to the control device 8 so that it can display it.
    In addition, the server 7 operates a recorder 70 which records the events which occur on the system. The events are for example the presentation of an identifier medium 33 to a terminal, the switching of a terminal from one state to another or an order sent from the control device 8.
    Also in addition, the manual entry device 36 is provided to change the state indicated by the main terminal 3 or the secondary terminal 4. The manual entry device 36 is for example protected behind a key door. The object of this input device is to compensate for a loss of communication between the terminal and the server 7. The manual input device 36 makes it possible to control the change of state in override mode.
    This change of state can be conditioned on the detection by the communication module 30 of the terminal of the absence of communication with the server 7, or between the secondary terminal 4 and the main terminal 3. The manual input device 36 comprises for example a first push button which makes it possible by successive presses to switch to the overriding mode or to leave it, and a second push button which makes it possible to switch from one state to another in the overriding mode.
    According to a second embodiment, different modes of intervention are managed. The system differs from the first embodiment in that the authorization to intervene in step 101 is accompanied by an indication of a mode of intervention. During the verification, in step 104, of the authorization sent by the main terminal 3 to the server 7, the latter also verifies that the person is part of the authorized team in connection with the mode of intervention. The server 7 is informed of the authorized intervention mode either because the information is transmitted with the request from the main terminal 3, or because the server 7 will have memorized the authorized intervention mode. If the person is not authorized, the alert mode as described above is triggered from step 117. In addition, it is possible to indicate with the control device 8 which predefined team can intervene. This provides an even finer way to control the people authorized to intervene.
    Provision can be made for one of the intervention modes, verified in step 105, to display, in step 107, a fourth state instead of the third state, that is to say when people are recorded in the list of people in intervention. This fourth state is for example flashing red. We are thus visually informed of the mode of intervention.
    The check can be supplemented by a check that a person presenting his identifier 33 is not already registered in intervention on another channel 1. An alert is generated in this case and access is not authorized. .
    In a third embodiment, the system differs from the first embodiment in that the main terminal 3 does not send a verification of the authorization of a person to the server 7, but is based on rules implemented by the control module 34 to determine whether or not the person is authorized to intervene. Such rules are for example an explicit list of identifiers, a range or several pages of identifiers when they can be sorted among themselves, or a combination of these rules.
    The system can be expected to have self-diagnostic functions. For example, each terminal is able to detect whether the fire module or the panel is functioning correctly. If this is not the case, the terminal control module generates a message to the server which can record this anomaly and generate an alert to the control device 8.
