Description

Technical Field

[0001] The present invention relates to a train signaling control system and, in particular, to a train sweeping method for a TACS, and a system, a device and a storage medium.BACKGROUND OF THE INVENTION

[0002] Compared with the conventional communication based train control system (CBTC), the autonomous train control system (TACS) based on train-to-train communication takes a "trains-centralized" way and can compute movement authority by carborne controller (CC). The essence of the TACS is to transfer the wayside control functions of the conventional CBTC system to the onboard system and optimize the system architecture, with reduction of the number of wayside equipment, thereby significantly reducing the equipment maintenance workload.

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

[0004] In the conventional CBTC system, the sweeping of degraded trains or non-communication trains relies on the detection of track occupancy to a great extent. The main track occupancy detection methods include track circuits and axle counters based on electromagnetic induction technology. However, the installation process of such secondary detection equipment is complex and needs a large number of cables, resulting in high construction and maintenance costs. In addition, the secondary detection equipment has the problem that correct sweeping cannot be completed due to its own failure.

[0005] After search, China Patent Publication No. CN114454923A discloses a train sweeping method and system based on an autonomous operation control mode. The method includes the following steps: an on-board device of a current train obtains axle counter status information from a switch controller; the on-board device of the current train obtains location information of other trains from on-board devices of other trains and the switch controller; the on-board device of the current train completes the sweeping of the current train according to the axle counter status information and the location information of other trains. The current urban rail transit train sweeping and determination function involves many equipment links with slow information transmission and determination, leading to a reduction in the efficiency of moving block tracking after the completion of train sweeping. In view of this problem, reallocating functions realizes combination of multiple mechanisms, reduces communication transmission, and improves the autonomous determination and control capabilities of on-board devices. Moreover, it may also be used in the autonomous train operation control mode. However, the cited reference still relies on the axle counter for train sweeping. Therefore, in the TACS, how to design a train sweeping technology that does not rely on the conventional secondary detection equipment has become a technical problem that needs to be solved.BRIEF SUMMARY OF THE INVENTION

[0014] As a preferred technical solution, the specific process of the manual train sweeping in step S105 is as follows: step S1051, the WRC computes that there is unknown train occupancy on the line and provides unknown train occupancy information to the ATS; step S1052, the ATS displays unknown train occupied line section information to the dispatching terminal; step S1053, based on the displayed occupancy information, the dispatching terminal authorizes and notifies a local operator to manually confirm whether there is an unknown train in a line section; step S1054: after confirming that there is no unknown train occupancy and entry in a manual sweeping zone, the local operator presses a wayside confirmation button; step S1055, an OC collects and sends sweeping button information to the WRC; step S1056, after collecting the manual sweeping button information, the WRC sends and provides manual sweeping zone confirmation information to the ATS; step S1057, the ATS prompts the dispatching terminal to perform manual sweeping confirmation on an interface; step S1058, the dispatching terminal performs confirmation on the interface of the ATS; step S1059: the ATS sends dispatching confirmation information to the WRC; step S10510, the WRC completes the sweeping processing of the manual sweeping zone; step S10511, the ATS displays information of successful sweeping; and step S10512, the dispatching terminal confirms that the sweeping is successfully completed.

[0023] Compared with the cited reference, the present invention has the following advantages: 1) The present invention completes the sweeping of sections of the entire line through communication train based automatic sweeping and manual confirmation, without the need to arrange secondary detection equipment such as axle counters or track circuits, thus getting rid of the reliance on conventional secondary detection equipment and greatly reducing the use of wayside equipment in the system, construction costs and maintenance workload, shortening the period of old line revamping and new line construction, and improving the competitiveness and flexibility of the system. 2) The present invention includes two means: automatic train sweeping and manual sweeping. For a main line, rapid automatic sweeping is performed by a communication train. For special sections such as complex crossovers, storage lines or rolling stock depots, rapid train sweeping is performed by combination of local operator button confirmation and central dispatcher authorization. Through the complementarity of the two means, the train sweeping function for all sections of the line can be easily completed, and the diverse and easily operatable train sweeping means of the TACS are ensured. 3) The present invention designs a set of illegal train intrusion detection system. When the WRC works normally, if a train illegally enters into a signalling zone, the train can be detected by the system, and then whether an unknown train currently enters into the line is determined. When it is confirmed that there is no illegal train on the line, trains are restarted or the line sections are unblocked; and after the trains are restored to positioning, the system can automatically complete the train sweeping based on the location information of all trains on the line without manual sweeping operations. In this way, the train sweeping efficiency of the TACS is ensured and the TACS is capable of rapid fault recovery. BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the invention will be clearly and completely described below in combination with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only some, not all of the embodiments of the invention. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the invention.

[0026] The TACS confirms the train occupancy status of line sections through automatic train sweeping and manual train sweeping. When the WRC is successfully powered on, the WRC is powered on and unlocked by a WRC initialization command to ensure that the WRC works normally, performs normal intrusion detection, and supervises the illegal entry of a train into a signalling zone during line section sweeping. Then, it is determined whether to perform automatic train sweeping operation according to the line section occupancy status provided by the WRC. When the automatic sweeping operation is completed, if there is still an unknown train occupied section in some special sections, manual sweeping operation needs to be performed to realize the process of train sweeping for all line sections.

[0027] As shown in FIG. 2, the present invention specifically includes the following steps: step S101, after a WRC is successfully powered on or restarted, powering on and unlocking the WRC by a WRC initialization command; step S102, determining a train occupancy status of line sections of an entire line by the WRC, if there is no unknown train occupancy status in the line sections, determining that line sweeping is successful; otherwise, executing step S103; step S103, performing automatic train sweeping and executing step S104; step S104, after the automatic train sweeping of the line is completed, determining whether there is still an unknown train occupied section; if yes, executing step S105; if not, determining that the line sweeping is successful; and step S105, performing manual train sweeping.

[0028] As shown in FIG. 3-1, for a track section connected to a train block, the track section may be configured as an automatic sweeping zone. When the minimum distance L from the front of communication train T1 to the train block is less than the minimum train length of the line, the track section may be automatically swept out. As shown in FIG. 3-2, for a signalling boundary, if train illegal intrusion detection equipment is arranged at the signalling boundary, when a track section where a switch is reversed is less than the minimum train length of the line, the section may be configured as an automatic sweeping zone. When the communication train T1 passes through the switch P1 and is positioned, the track section where the switch P1 is reversed may be automatically swept out. As shown in FIG. 3-3, when the length of a single crossover is less than the minimum train length of the line plus the length of a flanking zone, the crossover track section may be configured as an automatic sweeping zone. When the communication train T1 passes through the switch P3 and is positioned and train T2 passes through the switch P5 and is positioned, the crossover track section may be automatically swept out.

[0029] As shown in FIG. 4, when the length of the crossover does not meet the requirements for configuring as an automatic sweeping zone, in order to complete rapid train sweeping for the line section, the switch section may be configured as a manual sweeping zone, and whether there is an unknown train in the section is confirmed manually.

[0030] The schematic diagram of manual train sweeping interfaces in the TACS is shown in FIG. 5, which mainly involves interfaces between subsystems such as a wayside resource controller (WRC), a train controller (xTC), an object controller (OC), an automatic traffic supervision system (ATS), an intelligent operation and maintenance system (IOM), a train intrusion detection system (TID), and a sweeping button (CZB). When the system is successfully powered on, the ATS sends an operation task for line sweeping to the xTC according to the needs of train sweeping; the xTC applies for resources to the WRC; the WRC transmits line section occupancy display to the ATS, and the ATS sends to the WRC a manual sweeping command for dispatching; a local operator uses the CZB to confirm whether there is an unknown train in a section and sends button information to the OC; the OC sends the button information to the WRC; the TID detects whether there is a train illegally intruding into the signalling zone; the IOM displays an operating status of TACS equipment. Through the information interaction between various subsystems, the TACS process train sweeping.

[0032] The flow chart of automatic train sweeping of the TACS is shown in FIG. 6-1. The process of the automatic train sweeping is as follows: step S1031, the WRC computes that there is unknown train occupancy on the line and provides unknown train occupancy information to the ATS; step S1032, the ATS displays unknown train occupied line section information to a dispatching terminal; step S1033, based on the displayed occupancy information, the dispatching terminal determines to send to a train controller (xTC) an operation task for train sweeping; step S1034, the ATS sends to the xTC the operation task for sweeping; step S1035, the xTC applies for line resources according to the received task; step S1036, the WRC allocates line resources to the xTC; step S1037, the xTC computes a movement authority operating path and sends the movement authority operating path to the ATS; step S1038, the ATS displays operating path resource information to the dispatching terminal; step S1039, based on the resources applied for by the train, the dispatching terminal authorizes an operator to manually operate a train and performs line section sweeping; step S10310, the operator manually operates the train according to a dispatching command; step S10311, the xTC provides location information to the WRC in real time according to the location of the xTC; step S10312, the WRC sweeps the line sections according to the location information provided by the xTC; and when the automatic sweeping conditions for a section or automatic sweeping zone through which the physical location of the train passes are met, it is determined that there is no unknown train occupancy in the corresponding section; and step S10313, based on a sweeping result, the ATS confirms whether the line sections are done with the sweeping process.

[0033] The flow chart of manual train sweeping of the TACS is shown in FIG. 6-2. The process of the manual train sweeping is as follows: step S1051, the WRC computes that there is unknown train occupancy on the line and provides unknown train occupancy information to the ATS; step S1052, the ATS displays unknown train occupied line section information to the dispatching terminal; step S1053, based on the displayed occupancy information, the dispatching terminal authorizes and notifies a local operator to manually confirm whether there is an unknown train in a line section; step S1054: after confirming that there is no unknown train occupancy and entry in a manual sweeping zone, the local operator presses a wayside confirmation button; step S1055, an OC collects and sends sweeping button information to the WRC; step S1056, after collecting the manual sweeping button information, the WRC sends and provides manual sweeping zone confirmation information to the ATS; step S1057, the ATS prompts the dispatching terminal to perform manual sweeping confirmation on an interface; step S1058, the dispatching terminal performs confirmation on the interface of the ATS; step S1059: the ATS sends dispatching confirmation information to the WRC; step S10510, the WRC completes the sweeping processing of the manual sweeping zone; step S10511, the ATS displays information of successful sweeping; and step S10512, the dispatching terminal confirms that the sweeping is successfully completed.
