Description

Technical Field

[0001] The present invention relates to the field of train dispatching communications, and in particular to a method for implementing dispatching services in the case of train coupling. Background Art

[0002] my country's urban rail transit construction is currently developing rapidly and achieving significant success. During rail transit planning and design in various cities, flexible train marshaling technology is employed to dynamically adjust train marshaling during peak and off-peak periods, ensuring that train operations meet the demands of different time periods, while also addressing service levels, operating costs, and operational management requirements. For example, during peak periods, two three-carriage trains can be coupled into a single six-carriage train, while during off-peak periods, the trains can be separated and operated separately as two three-carriage trains. This ensures operational flexibility while reducing energy consumption and train wear, improving train operating efficiency, and lowering operating costs.

[0003] The coupling and uncoupling of subway trains places higher demands on train operations management. This is especially true for the train dispatching and communication system. Before coupling, the trains operate independently, each with its own train formation identification and dispatching and communication system. After coupling, the two trains operate in conjunction, requiring a new train formation identification and combined dispatching. After uncoupling, the two trains operate separately, each needing to restore its previous train formation identification and be dispatched independently. In this situation, a mechanism is needed to quickly and flexibly adjust information in the train dispatching and communication system in response to train coupling and uncoupling, ensuring that the train dispatching system can accurately dispatch trains and guaranteeing the reliability of various functions. Summary of the Invention

[0004] The technical problem addressed by this invention is to address the dispatching communication needs during subway train coupling and uncoupling operations by proposing a dispatching service processing mechanism for train coupling. By designing an interactive mechanism and process between the signaling system and the dispatching system, the issue of dispatching information changes during train coupling and uncoupling is resolved, ensuring the normal operation of command and dispatch functions during train operation.

[0005] The object of the present invention is achieved like this:

[0006] A method for implementing a train coupling dispatching service, wherein the process of implementing a train group calling service through a signaling system and a dispatching system is as follows:

[0007] The signal system provides the dispatch server with a query interface for periodic query of train location information and marshaling relationships. The train location information includes the train type, the leading train set number, the trailing train set number, and the coupled train set number. The signal system provides the dispatch server with a query interface for train location information and marshaling relationships.

[0008] During the coupling process, the signal system sends the trainset numbers of the two coupled trains, the trainset number of the leading train, the trainset number of the trailing train, and the trainset number of the coupled train to the dispatch server. After receiving the information, the dispatch server establishes a correspondence between the trainset number of the coupled train and the onboard radio communication group number of the leading train, and notifies the dispatch desk of the information. After receiving the information, the dispatch desk adds the trainset number and train information of the coupled train to the operation interface, and establishes a correspondence between the trainset number of the coupled train and the onboard radio communication group number of the leading train.

[0009] During the demultiplexing process, the signal system sends the trainset number of the demultiplexed train and the trainset numbers of the two small trains included in the demultiplexed train to the dispatching server; after receiving the information, the dispatching server deletes the trainset number of the demultiplexed train and deletes the corresponding relationship with the trainset number of the preceding train onboard radio; then the dispatching server notifies the dispatching console to delete the demultiplexed train on the operation interface; after receiving the information, the dispatching console deletes the demultiplexed train information and redisplays the trainset numbers of the two small trains that make up the demultiplexed train;

[0010] During the reversal process, the signal system sends the train set number of the reversing coupled train and the new train set numbers of the leading and following trains after the reversal to the dispatching server; after receiving the information, the dispatching server establishes a correspondence between the train set number of the reversing train and the current on-board radio call group number of the leading train, and notifies the dispatching desk of the information; after receiving the information, the dispatching desk updates the correspondence between the train set number of the reversing train and the on-board radio call group of the leading train in the background.

[0011] Furthermore, the signal system is used to obtain operational information including train coupling, uncoupling and reversing; the dispatching system includes a dispatching server, a dispatching console and an on-board console, which processes train call services, train passenger emergency intercom services and train broadcast services according to the train's formation status.

[0012] The signal system sends a message to the dispatching system to inform the status information of the train formation. The dispatching system adjusts the train formation number according to the changes in the train formation status.

[0013] Furthermore, when the dispatching station initiates a train broadcast, if it is a broadcast to a coupled train, it needs to carry the train set numbers of the two trains that make up the coupled train; the dispatching server backend initiates and processes the train broadcast service to the two small coupled trains respectively based on the correspondence between the coupled train and the small coupled train.

[0014] Furthermore, when sending a train passenger emergency intercom service, the dispatch server receives the passenger emergency intercom of the corresponding train and forwards it to the dispatch desk, which displays on the dispatch desk whether the preceding or following train of the corresponding train set initiated the passenger emergency intercom.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The method described in the present invention can ensure that the information of various systems is quickly synchronized in real time during the train coupling, reversing and uncoupling process, minimize the impact on existing business processes such as train calling, train broadcasting and passenger emergency intercom, and at the same time eliminate the need for complex information processing in the signal system and dispatching system.

[0022] 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 only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] A method for implementing a dispatching service in a train coupling situation includes the following contents:

[0024] (1) Information processing flow of the signal system.

[0025] The signal system periodically sends train status information to the dispatching system. This information needs to include the train's formation type, indicating whether it is a small formation train or a multiple-unit train.

[0026] The signal system provides the dispatching system with a query interface for train status information and marshalling relationships.

[0027] After a train is coupled, uncoupled, or turned back, the signal system sends the reconnected train information to the dispatching system. This information includes the following situations.

[0028] After the train coupling process is completed, the signal system sends the train set numbers of the two coupled trains, the front and rear relationship of the two trains, and the train set number after coupling to the dispatching system.

[0029] After the train unbundling process is completed, the signal system sends the train set number of the train before unbundling and the train set numbers of the two cars after unbundling to the dispatching system.

[0030] After the standing train reversal process is completed, the signal system returns the train set number of the reversing train and the train set numbers of the front and rear trains after the reversal to the dispatching system.

[0031] (2) Scheduling system information processing flow.

[0032] The dispatching system includes a dispatching server, a dispatching console, and onboard station equipment. The dispatching server receives train status information from the signaling system and distributes this information to the dispatching console. Based on the train status information, the dispatching console establishes a mapping relationship between the train car set number and the onboard station car set number, allowing it to call the onboard station using the car set number. When a train coupling message is received, a mapping relationship between the coupled train and the small-scale coupled train is established, and the information of the leading and trailing trains is recorded. The coupled train is displayed on the dispatching console, and the small-scale coupled train is deleted. When a train return message is received, the relationship between the leading and trailing trains of the coupled train is updated. When a train uncoupling message is received, the mapping relationship between the coupled train and the small-scale coupled train is deleted, and the small-scale coupled train is restored to display on the dispatching console.

[0033] The present embodiment will be further described below with reference to the accompanying drawings:

[0034] Taking two trains with train numbers 401 and 402 as an example, the train number after coupling is 801. The following describes the implementation process of the train call service for train coupling, reversing and decoupling, as well as the implementation process of passenger emergency intercom and train broadcasting services.

[0035] (1) The process of connection. Figure 1 As shown, after the signal system completes the train coupling, it assigns a new trainset number, 801, to the coupled train. Simultaneously, information about the coupled train is sent to the dispatch system's dispatch server, indicating that trainsets 401 and 402 are coupled, with the combined trainset number now being 801, with trainset 401 being the leading train and trainset 402 being the trailing train. Upon receiving this information, the dispatch server establishes a correspondence between the combined trainset number, 801, and the onboard station number of the leading train, 401. The dispatch server also displays train 801 on the dispatch console. After the coupling, the dispatch console initiates a train call for the combined train, using trainset number 801 as the callset. The corresponding onboard station number in the backend is the station number of the leading train, 401.

[0036] (2) Reentry process. Figure 2As shown in the figure, after the train reverses, the signaling system sends the reversing train's car number and the car numbers of the leading and following cars to the dispatching system. The information reads: Car number 801 reverses, and after the reversal, 402 becomes the leading car and 401 becomes the following car. Upon receiving this information, the dispatching server establishes a correspondence between the reversing train's car number 801 and the current onboard station of 402, and simultaneously sends this information to the dispatching desk for backend updates. After the reversal, the dispatching desk initiates a train call service for the reversing train, calling the car number 801. The backend's corresponding onboard station number is the onboard station of the leading car 402.

[0037] (3) Decompilation process. Figure 3 As shown in the figure, after the signaling system completes the train unbundling process, it sends information about the unbundled train to the dispatching system's dispatch server. The information indicates that trainset 801 has been unbundled, resulting in trains 401 and 402. Upon receiving this information, the dispatching server deletes the correspondence between trainset 801 and the current onboard station number. The dispatching server then deletes train 801 and restores the display of trains 401 and 402. The dispatching server then calls the unbundled train 401 or 402, initiating the call using the onboard station number corresponding to the original trainset number 401 or 402.

[0038] like Figure 4 、 Figure 5 Provides business processes for train broadcasting and passenger emergency intercom.

[0039] (4) Passenger emergency intercom service. Figure 4 This is the implementation process of the passenger emergency intercom service. The onboard PA initiates a passenger emergency intercom request, carrying the train information of train set 401. The dispatch server receives the passenger emergency intercom request from train 401 and forwards it to the dispatch desk, which displays the information that the passenger emergency intercom was initiated by the preceding or following train of train set 801.

[0040] (5) Train broadcasting services. Figure 5 This is the implementation process of the train broadcast service. In the train broadcast service, when the dispatching station selects train broadcast for car set 801, based on the train reconnection corresponding information, car set 801 corresponds to car sets 401 and 402. The dispatching station then splits car set 801 into car sets 401 and 402, and initiates train broadcast requests to the dispatching server for each. After receiving a response from the dispatching server, the dispatching station simultaneously initiates train broadcasts to the onboard PA systems of car sets 401 and 402, thus implementing the train broadcast function for car set 801.

[0041] In summary, the above are only preferred application examples of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
