Description

A train screening method, system, device and storage medium for a TACS system Technical Field

[0001] The present invention relates to a train signal control system, and in particular to a train screening method, system, equipment and storage medium of a TACS system. Background Art

[0002] Compared with the traditional CBTC system, the Train Autonomous Operation System (TACS system) based on vehicle-to-vehicle communication is "train-centric" and the train independently calculates mobile authorization. The essence of the TACS system is to transplant the trackside core control functions of the traditional CBTC system to the train, optimize the system architecture, and at the same time reduce the number of trackside equipment, significantly reducing the workload of equipment maintenance.

[0003] However, since the TACS system does not use traditional secondary detection equipment for train occupancy detection, the TACS system lacks an effective way to safely and reliably obtain the occupancy status of trains on the line section. Therefore, in the TACS system, how to screen trains on the line is a huge challenge.

[0004] In traditional CBTC systems, the screening of downgraded or non-communication trains relies heavily on track occupancy detection. The primary methods for detecting track occupancy include track circuits and axle counting based on electromagnetic induction technology. However, the installation of these secondary detection devices is complex, requiring extensive cabling and resulting in high construction and maintenance costs. Furthermore, the secondary detection devices are prone to failure, resulting in incomplete screening.

[0005] A search revealed Chinese patent publication number CN114454923A, which discloses a train screening method and system based on an autonomous operation control mode. The method comprises the following steps: the onboard equipment of the current train obtains axle counter status information from the switch controller; the onboard equipment of the current train obtains the location information of other trains from the onboard equipment of other trains and the switch controller; and the onboard equipment of the current train completes the screening of the current train by combining the axle counter status information with the location information of other trains. To address the current problem that the train screening and judgment function in urban rail transit involves multiple equipment links and slow information transmission and judgment speed, resulting in reduced efficiency for moving block tracking after the train is screened, this method redistributes functions, implements a combination of multiple mechanisms, reduces communication transmission, improves the autonomous judgment and control capabilities of the onboard equipment, and can also be used in the train autonomous operation control mode. However, existing patents still rely on axle counters for train screening. Therefore, in the TACS system, how to design a train screening technology that does not rely on traditional secondary detection equipment has become a technical problem that needs to be solved.

[0030] Step S10311: xTC provides location information to WRC in real time based on its own location;

[0031] Step S10312: WRC screens the route segments based on the location information provided by xTC.

[0032] In step S10313, ATS confirms whether the line section has completed the screening process based on the screening results.

[0033] As a preferred technical solution, in step S10312, when the automatic screening conditions of the section or automatic screening area through which the train physically passes are met, it is considered that there is no unknown train occupying the corresponding section.

[0034] As a preferred technical solution, the specific process of manual train screening in step S105 is as follows:

[0035] Step S1051, WRC calculates whether there is an unknown train occupying the line and provides the unknown train occupancy information to ATS;

[0036] Step S1052: The ATS displays information about the line section occupied by the unknown train to the dispatch terminal;

[0037] Step S1053: The dispatch terminal authorizes and notifies the local operator to manually confirm whether there is an unknown train in the line section based on the displayed occupancy information;

[0038] Step S1054: When the local operator confirms that there is no unknown train occupying the manual screening area and no unknown train entering, he presses the trackside confirmation button;

[0039] Step S1055: OC collects the filter button information and sends it to WRC;

[0056] Compared with the prior art, the present invention has the following advantages:

[0057] 1) The present invention eliminates the need for secondary detection equipment such as axle counters or track circuits, and instead completes the screening of entire line sections through automatic screening by communication trains and manual confirmation. This eliminates the reliance on traditional secondary detection equipment, significantly reduces the number of trackside equipment in the system, construction costs, and maintenance workload, shortens the cycle for old line reconstruction and new line construction, and improves the competitiveness and flexibility of the system.

[0058] 2) The present invention includes both automatic and manual train screening methods. For the main line, rapid automatic screening is performed using a communication train. For complex special sections such as crossovers, storage lines, or vehicle depots, rapid train screening can be performed using a combination of local operator button confirmation and central dispatch authorization. The complementary nature of these two methods facilitates train screening in all sections of the line, ensuring the diversity and ease of operation of the TACS system's train screening methods.

[0059] 3) The present invention has designed a train illegal intrusion detection system to ensure that when the WRC is working normally, if a train illegally enters the signal area, it can be detected by the system, so as to know whether there is an unknown train intruding on the line; when it is confirmed that there is no illegal train intruding on the line, when the train is restarted or the line section blockade is cancelled, when the train recovers its position, the system can automatically complete the train screening based on the position information of the trains on all lines, without the need for manual screening operations, thereby ensuring the train screening efficiency of the TACS system and giving the TACS system a fast fault recovery capability.

[0069] 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.

[0070] The TACS system uses both automatic and manual train screening to confirm the train occupancy status of line sections. After the WRC is successfully powered on, it is unlocked via the WRC initialization command to ensure normal operation and intrusion detection. During the line section screening period, the system monitors trains illegally entering the signal area. The system then determines whether to perform automatic train screening based on the line section occupancy status provided by the WRC. After the automatic screening is complete, if there are still unknown trains occupying certain sections, manual screening is required to complete the train screening process for all line sections.

[0071] As shown in FIG2 , the present invention specifically includes the following steps:

[0072] Step S101: After the trackside resource manager WRC is powered on or restarted, the WRC is powered on and unlocked through a WRC initialization command;

[0073] Step S102: WRC determines the train occupancy status of all line sections. If there is no unknown train occupancy status in the line section, the line screening is considered successful. Otherwise, step S103 is executed.

[0074] Step S103, perform automatic train screening and execute step S104;

[0075] Step S104: After the automatic train screening of the line is completed, it is determined whether there is still an unknown train occupying the section. If so, step S105 is executed; otherwise, the line screening is considered successful.

[0076] Step S105: Perform manual train screening.

[0077] As shown in Figure 3-1, the track section connected to the car block can be configured as an automatic screening area. When the distance L between the minimum head of the communication train T1 and the car block is less than the minimum vehicle length of the line, the track section can be automatically screened out; as shown in Figure 3-2, for the signal boundary, if a train illegal intrusion detection device is arranged, then when the switch reverse track section is less than the minimum vehicle length of the line, the section can be configured as an automatic screening area. When the communication train T1 passes through the switch P1, the track section of the reverse switch P1 can be automatically screened out; as shown in Figure 3-3, when the length of a single crossover is less than the minimum vehicle length of the line + the length of the side rush area, the crossover track section can be configured as an automatic screening area. When the communication train T1 passes through the switch P3 and the train T2 passes through the switch P5, the crossover track section can be automatically screened out.

[0078] As shown in Figure 4, when the length of the crossover does not meet the requirements for configuration as an automatic screening area, in order to quickly screen the trains in the line section, the switch section can be configured as a manual screening area, and manual confirmation is performed to determine whether there are unknown trains in the section.

[0079] The schematic diagram of the manual screening interface information of the TACS system train is shown in Figure 5, which mainly involves the interfaces between the subsystems such as the trackside resource manager WRC, the train controller xTC, the target controller OC, the automatic train monitoring system ATS, the intelligent operation and maintenance system IOM, the train intrusion detection system TID, and the screening button CZB. When the system is successfully powered on, the ATS sends the line screening operation task to the train controller xTC according to the needs of train screening. The train controller xTC applies for resources from the trackside resource manager WRC. The WRC transmits the line section occupancy display to the ATS, and the ATS sends the dispatcher's manual screening command to the WRC. The local operator confirms whether there is an unknown train in the section through the screening button CZB and sends it to the target controller OC. The OC sends the button information to the WRC. The train intrusion detection system detects whether there is a train illegally intruding into the signal area. The intelligent operation and maintenance system IOM can display the working status of the TACS equipment. Through information interaction between the subsystems, the TACS system can realize train screening.

[0080] The train screening interface information of the TACS system is shown in Table 1:

[0081] Table 1

[0082] The automatic train screening workflow of the TACS system is shown in Figure 6-1. The automatic screening workflow is as follows:

[0083] Step S1031, WRC calculates whether there is an unknown train occupying the line and provides the unknown train occupancy information to ATS;

[0084] Step S1032: The ATS displays information about the line section occupied by the unknown train to the dispatch terminal;

[0092] Step S10310: The driver manually drives the train according to the dispatching instruction;

[0093] Step S10311: xTC provides location information to WRC in real time based on its own location;

[0094] In step S10312, the WRC screens the line sections based on the location information provided by the xTC. If the train physically passes through a section or the automatic screening area meets the automatic screening conditions, it is considered that there is no unknown train occupying the corresponding section.

[0095] In step S10313, ATS confirms whether the line section has completed the screening process based on the screening results.

[0096] The automatic train screening workflow of the TACS system is shown in Figure 6-2. The manual screening workflow is as follows:

[0097] Step S1051, WRC calculates whether there is an unknown train occupying the line and provides the unknown train occupancy information to ATS;

[0098] Step S1052: The ATS displays information about the line section occupied by the unknown train to the dispatch terminal;

[0099] Step S1053: The dispatch terminal authorizes and notifies the local operator to manually confirm whether there is an unknown train in the line section based on the displayed occupancy information;

[0100] Step S1054: When the local operator confirms that there is no unknown train occupying the manual screening area and no unknown train entering, he presses the trackside confirmation button;

[0101] Step S1055: OC collects the filter button information and sends it to WRC;

[0102] Step S1056: After the WRC collects the manual screening button, it sends a confirmation message of providing the manual screening area to the ATS;

[0103] Step S1057: ATS prompts the dispatch terminal to perform manual screening and confirmation on the interface;

[0104] Step S1058: The dispatch terminal confirms on the ATS interface;

[0105] Step S1059, ATS sends scheduling confirmation information to WRC;

[0106] Step S10510, WRC completes the screening process of the manual screening area;

[0107] Step S10511, ATS displays a screening success message;

[0108] Step S10512: The dispatch terminal confirms that the screening is successfully completed.

[0109] The above is an introduction to the method embodiment. The following further illustrates the solution of the present invention through a system embodiment.

[0110] As shown in Figure 1, the train autonomous operation system (TACS) based on vehicle-to-vehicle communication mainly includes the trackside resource manager WRC, the trackside train controller WTC, the target controller OC, the automatic train monitoring system ATS, the onboard controller CC, the intelligent operation and maintenance system IOM, and the train intrusion detection system TID. The ATS subsystem of the automatic train monitoring system is responsible for supervising and controlling train operations, and has functions such as train tracking operation, alarm and event reporting, operation adjustment, and operation control. The trackside resource manager WRC is responsible for line resource allocation and recovery, and train line section occupancy management. The trackside train controller WTC is mainly responsible for managing and tracking faulty trains, taking over faulty trains to apply for and release resources, and interacting with adjacent trains. The target controller OC mainly realizes the status collection and drive of trackside equipment, including collecting the status of manual screening buttons on the trackside. The onboard controller CC requests and releases line resources according to the plan, actively controls the train, and realizes the train safety protection function and the train automatic driving function. The train intrusion detection system TID is mainly used to detect whether there are trains illegally intruding the signal area at the entrance of the TACS signal area. The intelligent operation and maintenance system IOM is mainly responsible for monitoring the working status of the equipment and providing alarms to maintenance personnel.
