Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and particularly to a method for setting and canceling train detention in a train control system. Background Art

[0002] At present, the CTCS2 (Chinese Train Control System, the second level of the Chinese train operation control system) + ATO system has been applied to intercity railways such as those in the Pearl River Delta. Due to the excellent interoperability characteristics of the CTCS-2 level train control system, some suburban railway lines with the need to be connected and operated with national railway lines also plan to adopt the CTCS2 + ATO system.

[0003] Suburban railways mainly serve urban agglomerations and urban suburban areas, and serve the commuting passenger flow between the central urban areas of urban agglomerations and surrounding town clusters and within the clusters. Its operation has the characteristics of high-density bus operation. Therefore, when considering adopting the CTCS2 + ATO system for suburban railways, an automatic reverse function is added to achieve the goal that the tracking and reverse intervals are no more than 3 minutes.

[0004] In order to meet the operation requirements of high-density bus operation of suburban railways, in addition to adding an automatic reverse function to the CTCS2 + ATO system, it is also necessary to consider adding the functions of setting and canceling train detention to provide more flexible dispatching means to meet the operation requirements of suburban railways. At present, the train detention function is widely used in the subway CBTC system, but for the CTCS2 + ATO system, there is still a lack of a systematic method for setting and canceling. Summary of the Invention

[0005] To solve the above problems, the present invention proposes a method for setting and canceling train detention for systems such as CTCS2 + ATO systems, CTCS-3 systems (including CTCS3 + ATO systems), CTCS-N (including CTCS-N + ATO) systems, and systems including a centralized traffic control system, on-board equipment, an interlocking system, and a station train control center, and corresponding train detention measures are executed after the target train stops stably, which can avoid emergency braking that may be caused by the train receiving these information prematurely and has high reliability.

[0006] To achieve the above object, the present invention proposes a method for setting and canceling train detention in a train control system, including the following steps:

[0008] The on-vehicle equipment of the target train, the interlocking system and the station train control center execute corresponding train detention measures or train detention cancellation measures on the target train according to the train detention order or train detention cancellation order.

[0009] Among them, in the method of setting train detention, after the dispatching centralized system receives the train stop steady information fed back by the target train, it sends the train detention order to the interlocking system and the station train control center successively.

[0010] Further, in the method of canceling train detention, after the dispatching centralized system receives the first confirmation cancellation information fed back by the target train, it sends the train detention cancellation order to the interlocking system and the station train control center successively.

[0022] Alternatively,

BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Figure 1 It is a schematic flow chart of the method for setting train detention in a train control system provided by an embodiment of the present invention;

[0046] Figure 2 It is a schematic flow chart of the method for canceling train detention in a train control system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.

[0048] The present invention is applied to a train control system, which includes a CTCS2+ATO system, a CTCS-3 system (including a CTCS3+ATO system), a CTCS-N (including CTCS-N+ATO) system, and a system including a centralized traffic control system, on-vehicle equipment, an interlocking system, and a station train control center. The structure and composition of the CTCS2+ATO system have changed during the application and development process. Its ground system was initially composed of a train control system (including a TCC station train control center, LEU, balise, etc.), a centralized traffic control system (CTC), a computer interlocking (CBI), a temporary speed restriction server (TSRS), a communication control server (CCS), and trackside signal basic equipment. Later, with the development of high-speed rail ATO technology, the CCS device was cancelled, and its functions have been merged into the TSRS for implementation. Currently, with the development of the train control and interlocking integration plan, the interlocking system and the station train control center in the CTCS2+ATO system will also be replaced by interlocking and train control integrated equipment in the future.

[0049] As described in the background art section, currently, the CTCS2+ATO system lacks a systematic method for setting and canceling train detention.

[0050] In view of this, the present invention proposes a method for setting train detention for a train control system, including the following steps:

[0051] The centralized traffic control system generates a train detention command and sends it to the target train. After receiving the train stop stability information feedback from the target train, the train detention command is then sent to the interlocking system and the station train control center corresponding to the target station where the target train is parked, and corresponding train detention measures are taken for the target train. In the present invention, after the target train stops stably at the target platform, the train detention command is sent to the interlocking system and the station train control center successively, and the train detention measures are taken after the target train stops stably, so as to avoid the emergency braking that may be caused by the target train receiving the train detention command information corresponding to the train detention measures prematurely.

[0052] Specifically, before the centralized traffic control system generates a train detention command, the centralized traffic control system adjusts the plan according to the train detention target, sets the target train to stop at the target platform, and sends it to the target train and the target station. The centralized traffic control system conducts train detention based on the train detention target adjustment plan, and only detains the trains set to stop at the target platform in this adjustment plan, so that more accurate train detention settings can be made at multi-direction stations, and the train detention settings for trains in different directions can be realized. The centralized traffic control system handles the reception and departure routes for all trains running on the line according to the train detention target adjustment plan, and the on-vehicle equipment of the target train controls the train operation according to the train detention target adjustment plan.

[0053] The car detention order is generated by the first dispatching console of the Centralized Traffic Control (CTC) system. The dispatcher can generate the car detention order by inputting the car detention order information in the man-machine interface of the first dispatching console. After generating the car detention order, it can be determined whether the car detention order needs to be verified based on the system configuration. If it is necessary, the car detention order will be sent to the second dispatching console in the CTC system for verification. The type of the second dispatching console is different from that of the first dispatching console. That is, if the first dispatching console is the train operation dispatching console, the second dispatching console is the assistant dispatching console; if the first dispatching console is the assistant dispatching console, the second dispatching console is the train operation dispatching console.

[0054] When verifying, the car detention order information is displayed on the operation interface of the second dispatching console for the dispatcher to confirm one by one; or the car detention order information is input on the second dispatching console, and the system judges whether the car detention order information in the two dispatching consoles is consistent to verify the validity of the car detention order information. If the car detention order information is not confirmed or the car detention order information in the two dispatching consoles is inconsistent, the car detention order fails to be verified, the car detention order is considered invalid information, the car detention order is discarded, and the process ends; if the car detention order is successfully verified, the CTC system sends the car detention order to the target train that stops at the target platform in the nearest train trip, and at the same time sets that the departure route of this train number at the target platform will not be automatically triggered.

[0055] After receiving the car detention order, the target train gives an early reminder to the driver according to the car detention order that the train will be detained at the target platform. When the target train arrives at and stops steadily at the target station, the on-board equipment sends a stop-steady message to the CTC system and simultaneously executes the corresponding car detention measures. After receiving the stop-steady message, the CTC system sends the car detention order to the interlocking system where the target platform is located. After receiving the car detention order information, the interlocking system forwards the car detention order information to the station train control center, and after receiving the first confirmation receipt message fed back by the station train control center, it feeds back the second confirmation receipt message to the CTC system. After receiving the second confirmation receipt message sent by the interlocking system, the CTC system displays a car detention mark at the corresponding track of the platform on its interface to complete the setting of the car detention order.

[0056] After receiving the car detention order, the target train, the interlocking system, and the station train control center take corresponding car detention measures. For example, the on-board equipment of the target train displays a car detention mark on the DMI according to the car detention order and prohibits the driver from starting the train; the interlocking system controls the corresponding outbound signal to display a stop signal according to the car detention order and shall not be opened until the car detention order is cancelled; the station train control center controls the corresponding track circuit of the track to send a stop code according to the car detention order information until the car detention order is cancelled. These car detention measures can be combined according to the specific line requirements to meet the car detention needs under different operation conditions.

[0057] Furthermore, asFigure 1 The following is a schematic flowchart of the method for setting train detention provided by an embodiment of the present invention for a train control system, including the following steps:

[0058] S1. Adjust the plan according to the detention target to set the target train to stop at the target platform, and send the detention target adjustment plan to the target train and the target station;

[0059] S2. The on-board equipment of the target train controls the train operation according to the adjustment plan;

[0060] S3. The first dispatching desk in the centralized traffic control system generates a detention order;

[0061] S4. Determine whether it is necessary to verify the detention order. If it is necessary, execute step S5; otherwise, directly execute step S7;

[0062] S5. Send the detention order to the second dispatching desk for verification. If the verification is passed, execute step S6; otherwise, execute step S7;

[0063] S6. Discard the detention order and end the process;

[0064] S7. The centralized traffic control system sends the detention order to the nearest target train that stops at the target platform, and at the same time sets that the departure route of this train number at the target station is not automatically triggered;

[0065] S8. The target train stops at the target platform until it stops stably, and sends a stop-stable message to the centralized traffic control system. At the same time, the on-board equipment of the target train displays a detention mark on the DMI and prohibits the driver from starting the train;

[0066] S9. After receiving the stop-stable message, the centralized traffic control system sends the detention order to the interlocking system where the target platform is located;

[0067] S10. The interlocking system sends the detention order to the station train control center, and at the same time controls the corresponding departure signal to display a stop signal according to the detention order;

[0068] S11. The station train control center sends a first confirmation receipt message to the interlocking system, and at the same time controls the corresponding track circuit of the track to send a stop code according to the detention order;

[0069] S12. After receiving the first confirmation receipt message, the interlocking system sends a second confirmation receipt message to the centralized traffic control system;

[0070] S13. After receiving the second confirmation receipt message, the centralized traffic control system displays a detention mark at the corresponding track of the platform on its interface;

[0071] S14. The detention setting is completed.

[0072] Based on the same inventive concept, the present invention also provides a method for canceling train detention in a train control system, including the following steps:

[0073] The centralized traffic control system generates a train detention cancellation command and sends it to the target train. After receiving the first confirmation cancellation information fed back by the target train, the train detention cancellation command is then sent to the target train, the interlocking system corresponding to the target station where the target train is parked, and the station train control center in sequence to lift the train detention measure for the target train.

[0074] Specifically, the train detention cancellation command is generated by the first dispatching console of the centralized traffic control system. The dispatcher can generate the train detention cancellation command by inputting the train detention cancellation command information in the man-machine interface of the dispatching console. After generating the train detention cancellation command, it can be judged based on the system configuration whether the train detention cancellation command needs to be verified. If so, the train detention command is sent to the second dispatching console in the centralized traffic control system for verification.

[0075] When verifying, the train detention cancellation command information is displayed on the operation interface of the second dispatching console for the dispatcher to confirm one by one; or the train detention cancellation command information is input on the second dispatching console, and the system judges whether the train detention cancellation command information in the two dispatching consoles is consistent to verify the validity of the train detention cancellation command information. If the train detention cancellation command information is not confirmed or the train detention cancellation command information in the two dispatching consoles is inconsistent, the train detention cancellation command has not been verified, the train detention command is considered invalid information, the train detention command is discarded, and the processing ends. If the train detention cancellation command is verified, the centralized traffic control system sends the train detention cancellation command to the target train parked on the target platform.

[0076] After receiving the train detention cancellation command, the target train cancels the train detention identification displayed on the DMI and cancels the taken departure restriction measures, and at the same time sends the first confirmation cancellation information to the centralized traffic control system. After receiving the first confirmation cancellation information, the centralized traffic control system sends the train detention cancellation command to the interlocking system. After receiving the train detention cancellation command, the interlocking system cancels the restriction of the departure signal machine, allows the route to be opened for signaling, and at the same time forwards the train detention cancellation command to the station train control center. After receiving the second confirmation message information fed back by the station train control center, it sends the third confirmation cancellation information to the centralized traffic control system. After receiving the train detention cancellation command, the station train control center cancels the track circuit coding restriction, allows the route to be opened and then sends an allowance code, and sends the second confirmation cancellation information to the interlocking system. After receiving the third confirmation cancellation information, the centralized traffic control system cancels the train detention identification displayed at the corresponding track of the platform on its interface.

[0077] Further, as Figure 2The following is a schematic flowchart of the method for canceling train detention provided by the embodiment of the present invention for the train control system, including the following steps:

[0078] S1. The first dispatching console in the centralized traffic control system generates a train detention cancellation command;

[0079] S2. Determine whether it is necessary to verify the train detention cancellation command. If it is necessary, execute step S3; otherwise, directly execute step S5;

[0080] S3. Send the train detention cancellation command to the second dispatching console for verification. If the verification is passed, execute step S5; otherwise, execute step S4;

[0081] S4. The train detention cancellation command is discarded and the process ends;

[0082] S5. The centralized traffic control system sends the train detention cancellation command to the target train;

[0083] S6. The target train cancels the train detention identifier displayed on the DMI according to the train detention cancellation command, allows the driver to depart, and at the same time sends a first confirmation cancellation message to the centralized traffic control system;

[0084] S7. The centralized traffic control system sends the train detention cancellation command to the interlocking system where the target station is located;

[0086] S9. The station train control center cancels the track circuit coding restriction according to the train detention cancellation command, allows the permission code to be sent after the route is opened, and at the same time sends a second confirmation cancellation message to the interlocking system;

[0087] S10. After receiving the second confirmation cancellation message, the interlocking system sends a third confirmation cancellation message to the centralized traffic control system;

[0088] S11. After receiving the third confirmation receipt message, the centralized traffic control system cancels the train detention identifier displayed at the corresponding track of the platform on its interface;

[0089] S12. The train detention cancellation is completed.

[0090] The present invention generates a train detention command or a train detention cancellation command through a centralized traffic control system, and successively sends them to the target train, the interlocking system corresponding to the target station, and the station train control center, so as to implement the corresponding train detention measures or train detention cancellation measures. In the method for setting train detention, after the centralized traffic control system receives the information that the target train has stopped stably, it sends the train detention command to the interlocking system and the station train control center successively, so as to avoid the emergency braking that may be caused by the target train receiving the train detention command information corresponding to the train detention measures prematurely. Since the train detention command is related to operation efficiency and safety, the present invention adopts a configurable verification process both when generating the train detention command and when canceling the train detention command, which can prevent the wrong setting of the train detention command or the train detention cancellation command when necessary, and improve the safety of the system. In addition, the centralized traffic control system conducts train detention based on the train detention target adjustment plan, and can perform more accurate train detention setting at multi-direction stations, so as to implement the train detention setting for trains in different directions. Moreover, after receiving the train detention command, the target train gives an advance prompt to the driver that the train will be detained at the target platform, realizing the advance notice of the train detention command.
