    The invention relates to methods for managing the circulation of a train along a section of a railroad, implemented by a signaling system of the type "Communication Based Train Control" - CBTC, the signaling system being able, in a nominal mode, to define a route on the section allowing the train to run in a nominal traffic direction, the route s 'extending over a plurality of successive zones between an origin signal and a destination signal.
    With a CBTC-type signaling system, a train travels along routes that are traced by a supervision system (ATS) and opened by a latching system (CBI).
    A road corresponds to a section of the railway track, which is traversed in a predetermined nominal traffic direction.
    A section groups together several successive zones between an origin signal and a destination signal.
    The tendency being to reduce the number of signaling signals along the track, the length of the sections and consequently of the roads increases.
    In the case of successive trains at relatively short intervals, as is the case for a metro line, it is expected that several trains can run simultaneously on the same section.
    However, if a first train breaks down on a section, the trains which have entered this same section and which follow it are prevented from continuing their journey.
    Indeed, in a CBTC architecture, when a train engages on a route which has been opened to it by the interlocking system, it must go as far as the destination signal.
    Thus, in the event of deviation from the nominal operation of the line, a large number of trains can be affected and must wait until nominal operation is resumed before continuing their journey according to the route on which they are engaged. The object of the invention is therefore to alleviate the aforementioned problem, in particular by proposing a degraded mode of traffic management by the CBTC signaling system, in which a train can be authorized to change the direction of travel when it has engaged on a road, to bring it out of the corresponding section of railway. To this end, the subject of the invention is a method for managing the circulation of a train along a section of a railway track, implemented by a signaling system of the CBTC type, the signaling system being suitable, in a nominal mode, for defining a route on the section allowing the train to run in a nominal running direction, the route extending over a plurality of successive zones between an origin signal and a destination signal, characterized in that it consists, in the event of an event preventing the train from continuing its movement along said route, in running the train in a direction of circulation opposite to the nominal direction of circulation: - by selecting a source area and an output signal; - by tracing, by a system of supervision of the signaling system, a pseudo-route for the train on the successive zones between the zone of origin and the exit signal; - by opening, by an interlocking device of the signaling system, the pseudo-route by associating with each zone between the zone of origin and the exit signal, a sub-route, each sub-route corresponding to the reservation of said area for said train in the opposite direction of travel; - by informing the train that it must change its current running direction so that it corresponds to the opposite running direction; and, - by determining, by a zone controller of the signaling system, a movement authorization for the train from the current running direction of the train and the open sub-routes for said train and taking into account a list of 'obstacles regularly updated by the area controller; - by transmitting the movement authorization to the train to control the movement of said train, the steps for determining and transmitting a movement authorization being iterated until the train crosses the output signal.
    According to particular embodiments, the method comprises one or more of the following characteristics, taken in isolation or according to all technically possible combinations: - the list of obstacles for a train moving in a current direction of circulation, includes all of the movement authorizations already transmitted to the other trains running on said section in the direction opposite to the current running direction; - the list of obstacles, for a train moving in a current direction of circulation, includes, in addition, a safety envelope calculated by the zone controller for another non-CBTC or CBTC non-communicating train running on said section ; - the list of obstacles, for a train moving in a current direction of circulation, also includes a safety envelope calculated by the zone controller for another CBTC train in manual driving running on said section in the opposite direction in the current traffic direction, the direction of travel of said CBTC train in manual driving being determined from an identifier of its active cabin; - the interlocking system locks a sub-route for a train as long as: said train occupies the area associated with said sub-route; or said train does not occupy the area associated with said sub-route, but a sub-route, which is associated with an area which precedes, according to the direction of travel of said sub-route, the area associated with said sub-route , is locked; - The method includes an initial step of selecting the train engaged on the section of track which must run in a direction of traffic opposite to the nominal direction of traffic; - The method comprises a configuration step consisting in defining each zone of the section of track likely to be used as the zone of origin of a pseudo-route. The invention also relates to a signaling system of the CBTC type for the implementation of a method for managing the circulation of a train along a section of a railway track in accordance with the preceding method, the system signaling system comprising a supervision system, a zone controller and an interlocking system, characterized in that: - the supervision system is capable of tracing a pseudo-route between an origin zone and a destination signal for said train; the interlocking system is capable of opening a pseudo-route traced by the supervision system, by defining, for each zone of the pseudo-route, a sub-route reserving, for said train, said zone in a direction of travel particular; and, - the zone controller is able to maintain a list of obstacles and to determine a movement authorization for the train, taking account of the list of obstacles.
    According to particular embodiments, the system includes one or more of the following characteristics, taken in isolation or according to all technically possible combinations: - the list of obstacles includes movement authorizations transmitted to the other trains running on the section; - the list of obstacles also includes safety envelopes calculated around each of the non-CBTC or CBTC non-communicating trains, running on the section; - the list of obstacles also includes safety envelopes calculated around each of the CBTC trains in manual driving, running on the section, each safety envelope being associated with an identifier of the active cabin of the CBTC train in manual driving correspondent; - the supervision system is configured so as to define the zones of the section of the railway likely to be able to be used as the zone of origin of a pseudo-route. The invention will be better understood with the aid of the description which follows, given solely by way of illustrative and nonlimiting example, and made with reference to the appended drawings in which: - Figure 1 is a schematic representation of a CBTC signaling system capable of implementing the method of managing the circulation of a train according to the invention; - Figure 2 is a schematic representation in the form of blocks of an embodiment of the method according to the invention; and, - Figures 3 to 9 show different stages of the operation of a line, equipped with the CBTC signaling system of Figure 1, operation during which the method according to the invention is implemented.
    FIG. 1 represents a signaling system 10 based on an ATC architecture (“Automatic Train Control”) of the “train management based on communication” type, also called CBTC architecture, for “Communication Based Train Control”. A CBTC architecture is based on the presence of computers on board trains, also known as the on-board part of an ATP (Automatic Train Protection) system.
    Thus, in the signaling system 10, the computer 6 of the train T provides, on the one hand, the coverage of the functional needs of the train T, that is to say for example the stations to be served, and, on the other On the other hand, the control of safety points, that is to say, for example, checking that train T does not have excessive speed at a particular kilometer point on the line.
    Thus, the computer 6 of the train T determines a certain number of operating parameters of the train T and communicates with different systems on the ground to allow the train T to safely carry out the mission assigned to it.
    The computer 6 is connected to at least one on-board radio communication unit 7, capable of establishing a radio link with base stations 8 of a ground communication infrastructure, itself connected to a communication network 19 of the architecture CBTC.
    On the ground, the signaling system 10 comprises an interlocking system 14, also called CBI according to the acronym for "Computer Based Interlocking". The CBI 14 is suitable for controlling track equipment, such as signaling lights, switch actuators, etc., this equipment allowing the safe movement of trains while avoiding conflicting movements between them. Formerly based on electromechanical relays, the interlocking system is now carried out by computer using suitable computers. The CBI 14 is located at a distance from the track equipment and is connected to the latter by a suitable communication network 13, preferably of the ETHERNET type. The CBI 14 comprises in FIG. 1 a storage memory 15, in particular for storing information relating to the sub-routes.
    The signaling system 10 comprises a zone controller 16, also called ZC ("Zone Controller"), which constitutes the ground part of an ATP ("Automatic Train Protection") system. ZC 16 is notably responsible, on the one hand, for monitoring the presence of trains on the rail network and, on the other hand, in a centralized architecture, for providing movement authorizations to trains. These movement authorizations must guarantee the safe movement of trains, that is to say for example not provide a train with a movement authorization which would lead it to go beyond the train in front. The ZC 16 comprises in FIG. 1 a storage memory 17, in particular for the storage of information relating to the obstacles to be taken into account in determining the movement authorizations.
    The signaling system 10 includes an automatic train supervision system 18, also known as an ATS system (“Automatic Train Supervision”). The ATS system 18 is implemented in an operational center and includes man / machine interfaces allowing operators intervene on the various components of the signaling system 10.
    The rail network 2 is subdivided into sections, each section extending between two signaling signals and being subdivided into a plurality of zones. In Figure 1, three successive areas, 24, 25 and 26 are shown. A section is traversed by a train in a predetermined nominal traffic direction D1. The occupation of an area is a fundamental fact of railway safety. The determination of this information, known to those skilled in the art, will now be presented in general.
    ZC 16 receives information from a primary detection system and from a secondary detection system and reconciles this information to determine occupied and free areas of the network.
    The primary detection system determines the area occupied by a train from the instantaneous position of the train calculated by its on-board computer. For example, this position is determined by the on-board computer from the detection of beacons located along the track and whose geographic positions are known, and from the measurements delivered by odometry sensors fitted to the train and allowing the calculator 6 to determine the distance traveled since the last crossed beacon. From the instantaneous position, the ZC 16 determines, by means of a network map of the network uniquely identifying each area, the area within which the train is located. The area is then placed in the "occupied" state. In this way, a first occupation information for each zone is determined by the ZC 16 and stored in the memory 17.
    The secondary detection system is suitable for redundant the primary detection system, in case, for example, the communication unit 7 of a train T no longer works and the ZC 16 can no longer obtain the instantaneous position of the train . While a “purely CBTC” system can work only with primary detection, a secondary detection system is necessary to, on the one hand, cover the modes of breakdown of on-board communication for a CBTC train and, on the other hand On the other hand, allow circulation on the network of non-CBTC trains, that is to say those that are not equipped with an on-board computer compatible with the CBTC architecture.
    By track sensors, the secondary detection system is able to detect the presence of a train in an area. As shown in FIG. 1, these sensors can be axle sensors 11 (“Axle Counter”) located at each end of an area, such as area 25. Thus, when the train T enters area 25, the upstream sensor 11 (in the direction of nominal traffic D1) allows the increment of a unit of a state counter associated with the zone 25, each time an axle 4 of the train T passes. train T leaves zone 25, the downstream sensor 11 makes it possible to decrement the same state counter by one unit, each time an axle 4 of train T passes. Thus, zone 25 is in the state "Free" when the associated status counter is equal to zero. Otherwise, zone 25 is in the "occupied" state.
    In another embodiment, these sensors are track circuits which make it possible to detect the presence of a short circuit between the rows of rails caused by the presence of the axle of a train.
    In these two embodiments, the secondary detection system comprises, in addition to a plurality of sensors 11, a plurality of intermediate equipment 12 making it possible to generate, from analog measurement signals at the output of the sensors 11, the information of occupation. This is transmitted via network 13 to CBI 14 and then to ZC 16.
    The method 100 according to the invention will now be described from FIG. 2, on the one hand, and from FIGS. 3 to 9, on the other hand.
    Figures 3 to 9 illustrate different times of traffic on railway line 2.
    Railroad 2 is subdivided into sections. Three sections A, B and C are shown in Figures 3 to 9.
    Section B comprises nine successive zones (referenced from 20 to 28) between the signaling signals S1 and S3.
    Zone 20, which incorporates a needle, has a common border with section A. When the needle is correctly positioned, a train can enter section B from section A.
    Zone 20 is surrounded by signals S1 and S2.
    Sections 21 to 28 are successive linear sections and define a train running track in a nominal running direction D1 (from left to right in Figures 3 to 9).
    The zones 21, 24, 26 and 28 are more particularly associated with stations 31, 32, 33 and 34 allowing the exchange of passengers.
    Zone 28 allows a train to leave section B by entering section C.
    Section C includes a zone 29, which incorporates a needle and is surrounded by two signals S3 and S4.
    In the nominal operating mode, section B is associated with a route R, delimited by the signal S1 as the origin signal and the signal S3 as the destination signal.
    As illustrated in Figure 3, for the completion of the mission of train T2 and as train T2 approaches the border between sections A and B, the ATS 18 traces, for train T2, the route A. ATS 18 communicates this route R to CBI 14.
    The CBI 14 opens this route R by reserving, for the train T2, each of the zones 20 to 28 in the direction of nominal circulation D1. Thus, for the train T2, the CBI 14 locks objects called sub-routes: a sub-route associates an area reserved for the train T2 and a direction of travel of the train T2 on this area. The sub-routes are stored in the memory 15 associated with the CBI 14.
    ZC 16 then determines, from the locked sub-routes for train T2 and the current running direction of train T2 corresponding to the nominal running direction D1, a movement authorization. This movement authorization is determined according to the areas of route R open for train T2 which are occupied by other trains. In this case, in FIG. 3, zone 27 is occupied by a train T1. The train T1 moves in the direction of nominal traffic D1. It precedes train T2 on section B. Consequently, the movement authorization issued to train T2 by ZC 16 extends as far as the border between zones 26 and 27.
    As shown in Figure 4, and according to the movement authorization it received from ZC 16, train T2 enters route R. It enters section B by crossing the original signal S1. It then progresses along route R. Each time train T2 crosses the border between two areas of route R, the CBI 14 releases the sub-route associated with the area that has just left train T2. Thus, in FIG. 4, when the train T2 is in zone 24, the zones 20 to 23 previously locked are now released. They are erased from the memory 15 of the CBI 14.
    The maintenance in the locked state of a sub-route by the CBI 14 meets the following two conditions: - the train for which the route was opened occupies the area associated with the sub-route considered; or - the train for which the route has been opened is not located in the zone associated with the sub-route in question, but the sub-route associated with the preceding zone, in the direction of nominal travel, the zone associated with the considered sub-route is in the locked state. Conversely, if one or other of these two conditions is not met, the CBI 14 releases the considered sub-route.
    In nominal mode, train T1 should continue its movement in the direction of nominal traffic D1 and eventually leave section B by crossing the signal S3. With each movement of train T1, ZC 16 determines the areas of route R which are no longer occupied by train T1 and updates the movement authorization of train T2. In nominal mode, train T2 should therefore continue to travel along route R to exit section B by crossing signal S3.
    However, in the event of an event preventing train T1 from continuing to move, train T2 is also prevented from continuing to move. In nominal mode, train T2 is blocked.
    Such an event may for example be a breakdown of the train T1 or a person on the track at the level of the zone 28 necessitating the interruption of the electrical supply in this zone so that the train T1 can no longer continue its movement.
    The method 100 according to the invention is then implemented in the following manner.
    When the event preventing the continuation of nominal operation occurs, an operator decides to switch the signaling system 10 to a degraded mode of operation of the line in which the trains are going to be allowed to turn back and their supervised safety maneuvers. In step 110, from the control center of the ATS 18, the operator takes the hand and selects a train engaged on the section of track considered to make it change direction of travel so that it comes out of the section considered. Thus, as illustrated in FIG. 5, the operator selects the train T2 so that it travels in an opposite direction of circulation D2, which is the direction opposite to the nominal direction of circulation D1, so that it emerges from the section B to which he entered. In step 120, after having selected a train from among the trains to turn around, the operator also selects the zone from which the selected train will be authorized to move in the opposite direction of travel D2 and the signal destination that the selected train must cross in order to leave the section it has entered.
    Advantageously, the zones from which to initiate a change in the direction of train running are predetermined. These are, for example, areas belonging to extended track sections on which several trains can be engaged at the same time. In general, on a section, these areas correspond to waiting areas where a train is brought when an event occurs before the decision is made to go into degraded mode. These are essentially zones corresponding to stations, such as zone 24.
    Thus, as represented by arrows in FIG. 5, the operator selects zone 24 as the origin zone of the maneuver and the signal S2 as destination or exit signal.
    This information is used by ATC 18 which, in step 130, traces, that is to say defines, a pseudo-route between the origin zone and the destination signal selected in step 120 for the train selected in step 110. This is a pseudo-route since a route is normally defined between two signaling signals, an origin signal and a destination signal. It is indeed the possibility of choosing a zone as the origin of a road rather than a signal which allows the automatic management of the maneuver by the signaling system.
    This pseudo-route once traced is indicated to the CBI 14, which opens it in step 140. To do this, the CBI 14 reserves, for the selected train, the different areas of the pseudo-route between the area of origin (included) and the destination signal, by associating with each of these zones a traffic direction corresponding to the opposite traffic direction. As shown in FIG. 6 by the arrows oriented from right to left, the pseudo-route PR is opened by the CBI 14 for the train T2 by locking zones 21 to 24 in the opposite direction of traffic D2.
    The CBI 14 stores and maintains the corresponding sub-routes in memory 15.
    It will be noted that, in FIG. 6, the train T2 being located in the zone 24, the sub-routes associated with sections 24 to 28 of the route R initially followed by the train T2 remain locked, the maintenance conditions being respected.
    In parallel, in step 150, the ATS 18, after having drawn the pseudo-route, informs the on-board computer of the selected train that it must change the current running direction of the train so that it corresponds to the direction of opposite traffic. Either the train is a fully automatic train and the on-board computer manages this change of direction by itself; or the train is steered and the driver is asked to change the cabin so that the active cabin, which was the head cabin when the train was traveling in the direction of nominal travel D1, is now the head cabin when the train moves in the opposite direction of travel D2. This change of active cabin is carried out in a secure manner by the use of a suitable key which the driver must use to indicate the active cabin.
    Once the active cabin change has been confirmed by the on-board computer, the latter transmits the current train direction information to the ZC 16.
    In our example, train T2 therefore informs ZC 16 that its current running direction is now direction D2.
    In the next step 160, the ZC 16, knowing the current running direction of the train and receiving from the CBI 14 the locked sub-routes for this train, calculates a movement authorization for this train. Thus, in our example, the ZC 16 knowing that the train T2 will now run in the direction D2, will periodically calculate a movement authorization from the sub-routes which have been reserved for it and which correspond to the opposite direction of traffic D2 .
    Gradually, the movement authorizations calculated by ZC 16 must allow train T2 to advance along the pseudo-route PR, until it crosses the destination signal S2 and comes out of section B.
    However, it may be that before starting the train traffic change maneuver or after this maneuver has been initiated, another train, T3 in Figures 5 to 9, has engaged in section B, c that is to say occupies an area of section B and moves in the direction of nominal circulation D1. There is therefore a risk that the train T2 which is now moving in the direction D2 finds itself face to face with the train T3 which is moving in the direction D1.
    According to method 100, to guarantee safety and avoid these face-to-face events, the ZC 16 takes into account, when it calculates a movement authorization for the train in question, a list of obstacles. This list of obstacles is kept up to date (step 200) by ZC 16.
    For train T2 moving in direction D2, the obstacles are defined from all the movement authorizations already calculated and transmitted for execution to the other trains running on section B and moving in direction D1.
    Thus, as illustrated in FIG. 7, if a movement authorization has already been transmitted to train T3, this movement authorization authorizing train T3 to go to the end of section 22, referenced by point P, then point P is considered an obstacle for train T2.
    ZC 16 then determines the movement authorization for train T2 taking into account the constraint that train T2, running in direction D2, must not be authorized to go beyond point P. Thus l movement authorization transmitted to train T2 cannot extend beyond zone 23.
    This way of proceeding therefore makes it possible to guarantee the safety of the train running in the opposite direction with respect to the risks of face to face with a train controlled by means of movement authorizations, that is to say of a train CBTC or compatible with the CBTC architecture.
    However, if traffic on track 2 is to be open to non-CBTC trains, it is also necessary that ZC 16 avoids all face to face between a train running in the opposite direction and a non-CBTC train.
    For this, the ZC 16 determines the zone over which the non-CBTC train is located at the current instant and calculates, around this instantaneous position, a safety envelope E. This case is shown in FIG. 8 by the thick line for train T3, considered in this figure as a non-CBTC train. The safety envelope E determined by ZC 16 for train T3 covers, by way of example, zones 21 and 22.
    This security envelope E constitutes an obstacle in the list to be taken into account for the determination of a movement authorization for the train T2 because it limits movement in the direction D2 (but not the direction D1). Thus in FIG. 8, if the safety envelope E of train T3 extends to point P, the movement authorization which will be calculated by ZC 16 for train T2 cannot extend beyond beyond point P (in direction D2). This avoids any risk of face to face between the train T2, which is a CBTC train, and the non-CBTC train T3.
    Once a movement authorization has been calculated for train T2, it is transmitted to the on-board computer of train T2.
    The train T2 on-board computer controls train T2 in accordance with this movement authorization. For example, as shown in FIG. 9, if the movement authorization given to train T2 makes it possible to advance to point P, train T2 leaves zone 24 and advances to zone 23.
    It will be noted that when leaving zone 24, the locking conditions of the sub-roads of the road R, in the direction D1, are no longer respected: as regards the sub-road associated with the zone 24 in the direction D1 , the train T2 is no longer in this area and the sub-route in the direction D1 which precedes (in the direction D1) that of the area 24, namely the sub-route associated with the area 23, is not locked. As a result, CBI 14 releases sub-route 24 for route R.
    Gradually all the sub-routes of the R route are released, the locking conditions no longer being respected until zone 27, which is locked by the train T1.
    When leaving zone 24, the conditions for locking the sub-route of the pseudo-route PR associated with zone 24 in the direction D2 are no longer checked and this sub-route is therefore released.
    On the other hand, the train T2 now occupying area 23, the sub-route of the pseudo-route PR associated with area 23 in the direction D2 is kept locked. The same applies to the sub-routes of the pseudo-route associated with the zones 22 and 21 in the direction D2, since the sub-route of the zone 23, which precedes the zone 22 in the direction D2 is locked. In step 170, the movement authorization calculated by ZC 16 is transmitted to the train for execution. The movement authorization is represented by a dotted arrow in FIGS. 7 and 8.
    As long as the train has not crossed the pseudo-route destination signal (step 180), the method 100 repeats step 160 to update the movement authorization of the train.
    Thus, for example, train T3 can be maneuvered so as to turn back. Each time the train T3 moves, the list of obstacles is updated (step 200) by the ZC 16, which allows it to update a movement authorization for the train T2.
    Gradually the train T2 moves along the pseudo-route and eventually crosses the signal S2. He then leaves section B. This puts an end to the maneuver and to the process 200.
    Another case consists of a T3 train which would be a CBTC type train but in manual driving, the safety mechanisms of the ATP system then being bypassed. However, train T3 communicates the identifier of its active cabin to the ground. The safety envelope E around the train T3 remains active preventing movement in the direction D2 of the train T2 on the corresponding zones only if the active cabin of the train T3 is the one on the right in the figures, this active cabin indicating that the train T3 moves in direction D1. As soon as the active cabin of train T3 changes to that on the left in the figures, indicating that train T3 is now running in direction D2, the safety envelope E which prevented train T2 from running in direction D2 disappears .
    If the T3 train of the CBTC type is non-communicating (in particular that it can no longer indicate its active cabin), there is no way of knowing the running direction of the T3 train. We find ourselves in the case of the systematic consideration of the safety envelope E as for a non-CBTC train. It is therefore only when the train T3 releases a zone, that the safety envelope will disappear allowing the second train T2 to advance over this zone by moving in the direction D2. The invention therefore makes it possible to operate the line in degraded mode allowing trains to travel on a portion of the track in the opposite direction to the nominal traffic direction. The invention makes it possible to control these movements in safety.
    For this, the invention defines new objects: - a pseudo-route defined between an origin canton and a destination signal, which allows the interlocking to define an alternative route for a train already engaged on a route; - a sub-route combining the reservation of an area of a section and a traffic direction in this area. The invention is particularly well suited to an unmanned automatic metro. The possibility of changing the direction of circulation of a train in a CBTC architecture is a characteristic allowing good flexibility in traffic management and optimal traffic management during the occurrence of blocking operational events in nominal mode. operating the line.
