Description

System, method and medium for realizing interconnection between TACS and CBTC Technical Field

[0001] The present invention relates to the field of rail transit train operation control systems, and in particular to a system, method and medium for realizing the interconnection between TACS and CBTC. Background Art

[0002] The TACS system is a train control system characterized by train-to-ground interlocking and vehicle-to-vehicle coordination, while the CBTC system is characterized by trackside interlocking and trackside coordination. However, in practice, the upgrade and reconstruction of CBTC lines and the interoperability of different systems within the network require the interconnection of the two train control systems. Currently, there are two major difficulties in achieving interoperability between the two systems. First, in terms of resource management, the TACS system is more sophisticated and does not have a concept of routes. Onboard controllers apply, lock, and release resources, while the CBTC system manages resources on a route-by-route basis, with trackside interlocking machines performing the application, locking, and release functions. Second, in terms of interval protection, the TACS system is decentralized, relying on direct communication between trains, while the CBTC system is centralized, with trackside regional controllers calculating and providing movement authorizations for each train based on its positioning reports.

[0003] The differences in resource management and interval protection between the two make it very difficult to achieve interconnection between the two. In order to achieve interconnection between the two, some manufacturers have adopted centralized or quasi-centralized interlocking in the TACS system to manage the access routes, and use a quasi-centralized system for interval protection.

[0004] A search revealed Chinese patent number CN115366954A, which discloses a system and method for compatible operation of TACS and CBTC. Specifically, the system includes a new interface for converting from a TACS subsystem to a CBTC subsystem; the TACS onboard equipment connects to the CBTC central ATS and CBTC trackside area controller via the new interface. However, this patent only enables compatible operation of trains equipped only with the TACS system on lines with both TACS and CBTC standards.

[0005] Chinese patent number CN114715229A discloses a signaling system architecture that integrates existing CBTC and TACS systems. Specifically, the ATS subsystem includes a train routing module, which works with the VOBC subsystem to implement train routing functions starting at the train end. The target controller includes a CI / OC fusion module and a ZC / OC fusion module. The CI / OC fusion module enables CBTC interlocking logic or resource management functions based on configuration options. When configured as a CBTC system, the CI system fully implements existing CI functions. When configured as a TACS system, the CBTC interlocking logic is disabled and resource management functions are enabled. The ZC / OC fusion module enables existing ZC functions based on configuration options. The VOBC subsystem includes an ATP module, an ATO module, a TOD module, and an STC module. However, this patent involves numerous modules and a complex configuration.

[0006] In summary, how to achieve the interconnection and interoperability of TACS and CBTC without changing their respective principles, and provide conditions for the subsequent upgrade and transformation of CBTC lines and the interoperability between different standards within the line network, is a technical problem that needs to be solved urgently.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0044] The present invention proposes a TACS and CBTC interconnection and interoperability implementation technology that can realize the interconnection and interoperability of the TACS system and the CBTC system. The system includes an intelligent operation and maintenance system IOM1, an automatic train monitoring system ATS2, a trackside resource manager WRC3, an object controller OC4, a data communication system DCS5, a compatible trackside train controller MWTC6, a compatible onboard controller MCTC7 (compatible with the TACS system and the CBTC system), and an inter-system interface, wherein:

[0045] 1. The MCTC can perform active resource management and interval protection based on vehicle-to-vehicle communication in the TACS system. It can also provide the CBTC system with the interface information required for the other party's area controller and other trackside equipment, including train positioning, in accordance with the specifications of the CBTC system to be operated. It can also receive CBTC movement authorization information sent by the other party's CBTC system and control train operations according to this movement authorization information.

[0046] 2. MWTC is mainly used to provide resource application, locking and unlocking functions for the faulty train when the TACS system fails (including when the train cannot communicate with the trackside). When the MWTC receives interface information including position messages sent by the CBTC train, it will apply for and lock resources for the train according to the train's operation mission provided by the ATS. It will also calculate the movement authorization for the CBTC based on the resource locking status and the position relationship between the CBTC train and its adjacent trains (including CBTC, TACS and non-communication trains) at this time, and send it to the CBTC train through the CBTC general interface message.

[0047] 3. The automatic train monitoring system ATS2, target controller OC4, trackside resource manager WRC3, and data communication system DCS5 all have the same configuration and functions as the current TACS system.

[0048] The present invention provides a method for realizing interconnection and intercommunication between TACS and CBTC, comprising the following steps:

[0049] 1) Under normal circumstances, the trains configured in the system operate in TACS mode, and the trackside uses TACS mode for resource management and interval protection;

[0050] 2) When a TACS train has a vehicle failure or communication interruption, the MWTC in the system manages resources for the train and interacts with the adjacent trains on its behalf to achieve the separation function;

[0051] 3) When a TACS train leaves the TACS system and enters the interconnected CBTC line, the train will use the CBTC and trackside interface message format to send relevant messages to the trackside ZC, CI and other equipment of the CBTC system, and perform safety protection and auxiliary operation management according to the authorization information provided by the CBTC system trackside;

[0052] 4) When a CBTC train that is interconnected with it enters the TACS system line, the TACS trackside MWTC equipment will receive the messages sent by the CBTC train. Based on these messages, the MWTC will manage resources based on the ATS plan and perform interval protection according to the CBTC moving block principle. It will calculate the movement authorization and send it to the CBTC train.

[0053] As shown in Figure 2, when train T1 on other CBTC lines wants to enter the TACS line, T1 needs to be taken over by the MWTC and obtain T1's position message. The MWTC then applies for line resources on behalf of T1 and communicates with other TACS trains. At the same time, the MWTC calculates a movement authorization for T1 based on the line resource allocation. Based on the obtained movement authorization, T1 operates in CBTC mode on the TACS line, achieving compatibility between TACS and CBTC trains.

[0054] As shown in Figure 3, when train T1 on other CBTC lines wants to enter the TACS line for operation, the following process is usually followed:

[0055] 1) CBTC train T1 enters the TACS area from the CBTC area according to the ATS operation task;

[0056] 2) T1 establishes a communication connection with the MWTC in the TACS trackside equipment 11 and sends a position message to the MWTC;

[0057] 3) MWTC is responsible for taking over the CBTC train T1 and applying for resources for T1 according to the operation mission;

[0058] 4) MWTC replaces T1 to communicate with other adjacent train T2;

[0059] 5) MWTC calculates the mobility authorization for T1 vehicle based on the applied line resources;

[0060] 6) MWTC sends the mobile authorization to T1;

[0061] 7) T1 controls the train to run on the TACS line based on the movement authorization received;

[0062] As shown in Figure 4, when a TACS train T1 is about to enter the CBTC line, T1 needs to send a position message to the CBTC wayside equipment 10ZC. The ZC calculates a movement authorization for it based on T1's position message and sends it to T1's MCTC. The MCTC controls the train T1 to run on the CBTC line based on the received movement authorization, thus realizing the interconnection and interoperability of TACS trains running on the CBTC line.

[0063] As shown in Figure 5, when train T1 on the TACS line is about to enter the CBTC line for operation, the following process is usually followed:

[0064] 1) TACS train T1 enters the CBTC area from the TACS area according to the ATS operation task;

[0065] 2) T1 establishes a communication connection with the CBTC trackside equipment 10;

[0066] 3) MCTC sends a location message to ZC according to the CBTC interface format;

[0067] 4) After receiving T1's location message, ZC calculates the mobility authorization for T1;

[0068] 5) ZC sends the mobile authorization to MCTC;

[0069] 6) MCTC protects train T1 and controls train movement based on the movement authorization received;

[0070] The above is an introduction to the method embodiment. The following further illustrates the solution of the present invention through a system embodiment.

[0071] As shown in Figure 1, the system for implementing the interconnection between TACS and CBTC in the present invention includes an intelligent operation and maintenance system IOM1, an automatic train monitoring system ATS2, a trackside resource manager WRC3, an object controller OC4, a data communication system DCS5, a compatible trackside train controller MWTC6, a compatible onboard controller MCTC7, trackside equipment 8, and a transponder 9. Among them, the MCTC is mainly responsible for active resource management and interval protection functions based on vehicle-to-vehicle communication, and can control and protect train operation according to the CBTC mobile authorization information sent by the CBTC trackside system. The MWTC is mainly responsible for managing and tracking faulty trains, taking over the faulty train for maintenance, and Resource application and release, and is also responsible for managing temporary speed limits. In addition, when the MWTC receives interface information including location messages sent by the CBTC train, it will apply for and lock resources for the train based on the train's operating tasks provided by the ATS, and calculate the movement authorization for the CBTC train and send it to the CBTC train; WRC is responsible for line resource allocation and recovery, train sequence management and other functions; OC is responsible for the drive and status collection functions of trackside equipment 8; the ATS subsystem is responsible for supervising and controlling the operation of the train, and has functions such as train tracking operation, alarm and event reporting, operation adjustment, and operation control; IOM is mainly responsible for functions related to equipment maintenance.
