[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should belong to the scope of protection of the present application.

[0039] As Figure 1As shown, a train operation control system based on flexible route control includes a train plan management system ATS, a route management system RMS, a trackside equipment management system TEMS, a train control system, and a train-ground wireless transmission system. The route management system further includes a turnout area management module and an interval management module. The train control system further includes a trackside area management system and an on-board control system.

[0040] The ATS and the route management system are designed in a centralized and integrated manner and have a full-line management function, and are generally deployed in a control center. The trackside area control system of the train control system can be controlled in regions according to the length of a line. The trackside equipment management system is designed in a split manner and is deployed in a device centralized area and connected to the train route management system through a backbone network.

[0041] The train plan management system adopts an ATS system and is connected to the train route management system and the trackside area management system through a network to manage the operation plan and the route of a train.

[0042] The trackside area management system is connected to the ATS system and the route management system through a wired network and is connected to the on-board control system through a train-ground wireless network to protect a train in a region.

[0043] The route management system is connected to the ATS system, the trackside equipment management system, and the trackside area management system through a wired network and is connected to the on-board control system through a train-ground wireless network to manage a route on a line.

[0044] The trackside equipment management system is connected to the route management system through a wired network and is connected to trackside equipment such as an axle counter, a turnout, and a signal machine through a hard-wired interface to manage the trackside equipment.

[0045] The train-ground wireless transmission subsystem adopts LTE and / or WLAN.

[0046] The destination information and the full-line operation route information of each train are included in the plan task of the ATS system, and the destination information is divided into the destination of a next stop point and the destination of a one-way train. The ATS system sends the destination information and the operation route information to the route management system in real time as a necessary condition for establishing a route.

[0047] The route management system includes a turnout route management module and an interval route management module, and the turnout route management module mainly manages the route of a region where a turnout is located, and the interval route management module mainly manages the route of an interval region without a turnout.

[0048] The train route management system is responsible for dividing and managing the routes in the whole line. The division of the routes is independent of the signal machines. The train route management system takes the train as the establishment object and manages the routes in a virtual route manner. The minimum route unit is a single axle-counting section. The train route management system shares the route information in the whole line with the ATS system in real time and can obtain the path information of all routes in the whole line.

[0049] The train route management system uniformly manages all routes, including route establishment, route locking, route unlocking, route cancellation, and route conflict checking.

[0050] The train route management system establishes and locks the routes according to the destination information in the train operation plan and the occupancy information of the trigger section. In combination with the route information in the whole line, the train route management system checks the conflicting routes and checks whether the switch position is in the specified position. If the switch position is not in the specified position, the train route management system sends the route information to the trackside equipment management system and controls the relevant switch to be operated to the specified position.

[0051] The train route management system checks the occupancy state of the routes in the whole line in real time. When the route is established, the train route management system checks whether the route between the current route and the next stopping point is occupied in real time. If the route is occupied, the end of the route is the tail protection point of the previous train. If the route is not occupied, the end of the route is the next stopping point.

[0052] The train route management system sends the route locking state, direction information, signal machine state, switch position and other information to the train control system to control the train operation.

[0053] The train route management system controls the route to be dynamically unlocked along with the movement of the train according to the real-time position information of the train sent by the train control system. The route can be manually cancelled by cancelling the destination of the train, and the route can be automatically cancelled in a delayed or immediate manner.

[0054] The train route management system has a memory function for the destination information. When the train route management system loses communication with the ATS system, the train route management system can maintain the current train operation to the next stopping point.

[0055] The trackside equipment management system checks the switch position information in real time according to the route establishment information sent by the train route management system. When the switch position is consistent with the requirement of the route, the route is immediately locked. When the switch position is not consistent with the requirement of the route, the trackside equipment management system outputs a switch operation command. After the switch is operated to the specified position, the route is locked. After the route is established and locked, the trackside equipment management system controls the opening of the corresponding signal machine according to the route establishment and locking information sent by the train route management system. Specific embodiments

[0057] For example, Figure 1As shown, the train operation control system based on flexible route control includes an ATS, a ZC, a CC, an RMS, and a TEMS. The ATS is a train plan management system, the ZC is a trackside area control system, the CC is a vehicle-mounted control system, the RMS is a train route management system, and the TEMS is a trackside equipment management system.

[0058] The route management system RMS is connected to the ATS through a wired network. The RMS receives destination information sent by the ATS and establishes and locks a route according to the destination. The RMS feeds back route status, trackside equipment status, and axle counter status to the ATS system.

[0059] The RMS is connected to the train control system and receives train position information and train stop information. The RMS dynamically unlocks a route according to train position information and determines whether to delay unlocking a route according to train stop information.

[0060] The TEMS is connected to the RMS. When route conditions are met, the TEMS receives switch operation information from the RMS, outputs switch operation commands, controls trackside switches, and collects switch status and feeds back the switch status to the RMS system.

[0061] When signal opening conditions are met, the TEMS controls outdoor signals, collects signal status, and feeds back the signal status to the RMS system.

[0062] The RMS is also responsible for collecting axle counter status and feeding back the axle counter status to the RMS system.

[0063] The ZC dynamically calculates a train movement authority according to route locking status, route direction, signal status, and switch position information. The CC controls train operation according to the train movement authority.

[0064] For a planned train, the train operation plan task contains a destination 1 and a destination 2 for each train. The destination 1 is a next target stop point, and the destination 2 is a one-way terminal target point.

[0065] When relevant route conditions are met, a switch route and an interval route establish a route to the destination 1 according to the destination 1. When a train reaches a trigger section of the route, the route is locked. According to a switch included in the route, a real-time check is performed on the switch position. If the position is not in a specified position, the trackside equipment management system moves the switch to the specified position and locks it. After the route is locked, the RMS controls the opening of a signal on the route and sends relevant information to the train control system as a voucher for the train control system to calculate a movement authority.

[0066] For CBTC train, CC sends train position information to route management system in real time as train moves, and route management system dynamically unlocks route according to train position movement. For backup train, route is automatically unlocked once train runs through route area.

[0067] Manually cancel the route of planned train as follows:

[0068] When manually canceling destination 1 of train but destination 2 still exists, all routes already handled for the train remain unchanged, the train running in section is stopped by emergency braking, and the train stopped in section is not dispatched.

[0069] When manually canceling destination 2 of train but destination 1 still exists, the route to next target point already handled for the train remains unchanged, and the train runs to the next stopping point and stops until a new target point is manually set.

[0070] When both destination 1 and destination 2 of train are canceled, all routes handled for the train are delayed or immediately canceled, and the train running in section is stopped by emergency braking.

[0071] For non-planned train, manually set destination 1 for the train, when the relevant route condition is met, switch route and section route establish route to destination 1 according to destination 1, when the train reaches the trigger section of the route, start to lock the route, need to operate the switch to the specified position, after locking is completed, the route signal is opened, the relevant information is sent to the train control system as the voucher for the train control system to calculate the movement authority.

[0072] Manually cancel the route of non-planned train as follows:

[0073] When manually canceling destination 1 of train, all routes handled for the train are immediately canceled, and the train running in section is stopped by emergency braking.

[0074] By manually canceling destination 1 and manually setting destination 1, reverse route can be arranged for section train, so as to achieve the purpose of reverse running of train in section.

[0075] If train needs to run reversely in section, destination 1 and destination 2 are canceled at the same time. The route of train running forward is canceled. The reverse destination is specified for the train, and all routes of the train to the reverse destination are established. The train control system controls the reverse running of train according to the movement authority.

[0076] Specific implementation steps:

[0077] For example Figure 2As shown, the planned task management of the ATS contains train operation to the next stop destination 1, and train one-way end destination 2. After the train operation to the next stop, the destination 1 is automatically updated to the next stop. After the train operation to the end turnaround station, the destination 2 is automatically updated to the next one-way end.

[0078] As shown, Figure 3 As shown, the station A to station B is arranged with the counting points AC1-AC5, which divide three routes, namely the route R1 from AC1 to AC2, the route V1 from AC2 to AC3, and the route V2 from AC3 to AC5.

[0079] The train 1 is at the platform A, and the destination of the train 1 to the station B is set according to the plan. The station A is the trigger section of R1, V1, and V2, which triggers the turnout route R1 and the section routes V1 and V2, respectively. The turnout position of the route R1 is required to be positioned, and the turnout is controlled to be positioned by the TEMS according to the route command; after the turnout position is correct, the route R1 is locked, and the signal S1 is opened to allow the signal.

[0080] The train 1 controls the train to enter R1 and run in the section according to the information such as the route locking state, the route direction, and the signal state, and the routes R1 and V1 are dynamically unlocked with the movement of the train.

[0081] The train 2 reaches the station A, and handles the turnout route R1' and the section routes V1' and V2'. Since the train A is still in the section, the route range of V2' is to the tail protection point of the train 1. With the movement of the train 1, V2 is dynamically unlocked, and V2' is dynamically established.

[0082] As shown, Figure 4 As shown, the train 1 and the train 2 are between the station A and the station B, respectively. The destination 1 and the destination 2 of the train 2 are manually cancelled, and at this time, the route V2 handled for the train 2 will be cancelled, and if the train 2 is still running, the train will be stopped by emergency braking.

[0083] The reverse destination of the train 2 to the station A is handled, and the routes V3, R2, and V4 to the station A are established and locked, and the train 2 reversely runs according to the movement authorization.

[0084] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
