Description

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 autonomously 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 the traditional CBTC system, the screening of downgraded trains or non-communication trains depends largely on the detection of track occupancy. The main means of track occupancy detection include track circuits and axle counting based on electromagnetic induction technology. However, the installation process of such secondary detection equipment is complicated, requiring the layout of a large number of cables, and the construction and maintenance costs are high. In addition, the secondary detection equipment may fail to complete the correct screening due to its own failure.

[0005] After searching, Chinese patent publication number CN114454923A discloses a train screening method and system based on autonomous operation control mode, the method includes the following steps: the on-board equipment of the current train obtains the axle counter status information from the turnout controller; the on-board equipment of the current train obtains the location information of other trains from the on-board equipment of other trains and the turnout controller; the on-board equipment of the current train completes the screening of the current train in combination with the axle counter status information and the location information of other trains. Aiming at the problem that the current urban rail transit train screening and judgment function involves many equipment links and the information transmission and judgment speed is slow, resulting in the problem that the efficiency of mobile block tracking after the train is screened is reduced, by redistributing the functions, realizing the combination of multiple mechanisms, reducing communication transmission, improving the autonomous judgment and control capabilities of the on-board equipment, and can also be used for the train autonomous operation control mode. However, the existing patents still rely on axle counter equipment 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.

[0068] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work should fall within the scope of protection of the present invention.

[0069] The TACS system confirms the train occupancy status of line sections through automatic train screening and manual train screening. When the WRC is powered on successfully, the WRC is powered on and unlocked through the WRC initialization command to ensure that the WRC can work normally and perform normal intrusion detection. During the line section screening, the trains that illegally enter the signal area are monitored; then, according to the line section occupancy status provided by the WRC, it is decided whether to perform automatic train screening operations. After the automatic screening operation is completed, if there are still unknown train occupation sections in some special sections, manual screening operations need to be performed to realize the processing of train screening for all line sections.

When the communication train T1 passes through the turnout P1, the turnout P1 reverse track section can be automatically screened out; Figure 3-3 As shown, when the length of a single crossover is less than the minimum vehicle length of the line + the length of the side rush zone, 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.

[0077] like Figure 4As shown, when the length of the crossover does not meet the requirements for configuration as an automatic screening area, in order to quickly screen trains in the line section, the turnout section can be configured as a manual screening area, and manual confirmation is performed to determine whether there are unknown trains in the section.
