Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a train control method, device, equipment and medium that supports cross-line operation. Background Technology

[0002] To achieve the "four-network integration" of trunk railways, intercity railways, suburban railways, and urban rail transit, it is necessary to integrate the CTCS and CBTC systems to support cross-line operation of CTCS and CBTC. However, to achieve cross-line operation, it is necessary to configure overlapping areas for CTCS and CBTC lines.

[0003] In existing technologies, both CTCS ground equipment (such as CTCS transponder groups) and CBTC ground equipment (such as CBTC transponder groups) are deployed simultaneously in the shared management area where the CTCS and CBTC jurisdictions overlap. This allows trains to obtain ground information in both systems within the shared management area, enabling safe train control and switching of control rights. However, deploying CTCS and CBTC transponder groups separately in the shared management area results in a large number of transponder groups and high construction costs. Furthermore, if the train's track route within the shared management area is short, the large number of transponder groups can cause the onboard equipment to receive a large amount of transponder data in a short period. If the onboard equipment has limited performance, it may be unable to process all the transponder data in a short time, leading to equipment failure or data loss, reduced transportation efficiency, and even safety hazards. Summary of the Invention

It can reduce the number of transponders configured in the shared area, improve the utilization rate of transponders, reduce construction costs, support trains to cross CTCS and CBTC lines without stopping, and enable safe cross-line operation, thereby improving the transportation efficiency of trains.

[0025] Thirdly, this application provides an electronic device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores a computer program executable by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to execute the train control method supporting cross-line operation as described in any embodiment of this application.

[0026] Fourthly, this application provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the train control method supporting cross-line operation as described in any embodiment of this application.

[0027] To address the shortcomings of existing technologies, this application provides a train control method supporting cross-line operation. This method offers the following advantages: A shared management area for CTCS and CBTC is established at the boundary between the CTCS and CBTC management areas. Hybrid transponders containing both CTCS and CBTC ground information are configured within this shared management area. Compared to existing technologies, this reduces the number of transponders required in the shared management area, improves transponder utilization, and lowers construction costs. It also avoids the problem of onboard equipment receiving a large amount of transponder data in a short time due to a large number of transponder groups, which prevents the onboard equipment from processing all the transponder data in a timely manner. When a train enters the shared management area, the onboard equipment receives hybrid transponder messages from the hybrid transponders. The CTCS main control unit and the CBTC main control unit select the necessary information from the hybrid transponder messages. A switching execution command is obtained by parsing the first ground information corresponding to the first main control unit, and then the switching execution command is used to perform the task of switching control between the first and second main control units within the shared management area.

[0028] It should be noted that the aforementioned computer instructions may be stored, in whole or in part, on a computer-readable storage medium. This computer-readable storage medium may be packaged together with the processor of the train control device supporting cross-line operation, or it may be packaged separately from the processor of the train control device supporting cross-line operation; this application does not impose any limitations on this.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0040] Figure 1 This is a first flowchart illustrating a train control method supporting cross-line operation provided in this application embodiment. This embodiment is applicable to situations where train control authority is switched between the CTCS main control unit and the CBTC main control unit when the train travels to a shared area overlapping between the CTCS and CBTC jurisdictions. The train control method supporting cross-line operation provided in this embodiment can be executed by the train control device supporting cross-line operation provided in this application embodiment. This device can be implemented through software and / or hardware and integrated into the electronic device executing the method. Preferably, the electronic device in this application embodiment can be a train.

[0041] See Figure 1 The method in this embodiment includes, but is not limited to, the following steps:

[0042] S110. When the train enters the shared area, receive the mixed transponder message sent by the mixed transponder.

[0043] The train control system of this application includes a hybrid transponder and onboard equipment. An integrated onboard system compatible with CTCS and CBTC is configured on the train, comprising a CTCS main control unit and a CBTC main control unit. A shared CTCS and CBTC control area is established at the boundary between the CTCS and CBTC control areas. This shared area refers to the overlapping portion between the CTCS and CBTC control areas. A hybrid transponder containing both CTCS and CBTC ground information is configured within this shared area. The hybrid transponder is used to send ground control information (i.e., CTCS ground information and CBTC ground information) to the train. Optionally, the hybrid transponder can be a group of hybrid transponders, i.e., a hybrid transponder group.

[0044] like Figure 2 The diagram shows a train operating across lines. It illustrates that the train is equipped with integrated onboard equipment compatible with CTCS and CBTC. CTCS transponder groups are configured in the CTCS jurisdiction area, CBTC transponder groups are configured in the CBTC jurisdiction area, and hybrid transponders are configured in the shared area (i.e., the CTCS / CBTC overlap area in the diagram). In the CTCS jurisdiction area, the CTCS main control unit performs the train control task, in the CBTC jurisdiction area, the CBTC main control unit performs the train control task, and in the shared area, the train control right needs to be switched.

[0045] Preferably, in order to simplify the train control system and improve its efficiency, a unified transponder antenna and transponder information receiving unit can be set up on the onboard equipment. The transponder antenna is used to receive the mixed transponder message containing ground control information sent by the mixed transponder.

[0046] In this embodiment, when a train is detected entering a shared area, the hybrid transponder sends transponder data to the transponder antenna on the train. The transponder information receiving unit receives this transponder data through the transponder antenna and processes it according to a preset data processing method to obtain a transponder message conforming to the protocol standard, denoted as a hybrid transponder message. Optionally, the transponder information receiving unit can send the hybrid transponder message to the CTCS master control unit, while the CTCS master control unit forwards all hybrid transponder messages to the CBTC master control unit. The hybrid transponder can be a transponder containing both CTCS ground information and CBTC ground information, and the hybrid transponder message can be a transponder message containing both CTCS and CBTC transponder messages.

[0047] S120. The CTCS ground information is selected from the mixed transponder messages by the CTCS master control unit, and the CBTC ground information is selected from the mixed transponder messages by the CBTC master control unit.

[0048] The mixed responder message includes multiple sub-data packets.

[0049] Specifically, the CTCS master control unit selects CTCS ground information from the mixed transponder messages. This process includes: the CTCS master control unit first parses the header of the mixed transponder message, and then iterates through and parses all the sub-data packets carried after the header. The sub-data packet parsing process is as follows: obtain the attribute information of the current sub-data packet, which includes at least the sub-packet number and sub-packet length; determine whether the current sub-data packet is a CTCS sub-packet based on the sub-packet number in the attribute information; if it is a CTCS sub-packet, parse the CTCS sub-packet to obtain the corresponding sub-ground information; if it is not a CTCS sub-packet, skip the current sub-data packet and search for the next sub-data packet based on the sub-packet length in the attribute information, and continue parsing the next sub-data packet; after traversing all the sub-data packets, obtain multiple corresponding sub-ground information, and merge the multiple sub-ground information into the CTCS ground information.

[0050] The CBTC master control unit selects CBTC ground information from the hybrid transponder messages, including: the CBTC master control unit first parses the header of the hybrid transponder message, and then iterates through and parses all the sub-data packets carried after the header. The sub-data packet parsing process is as follows: obtain the attribute information of the current sub-data packet, which includes at least the sub-packet number and the sub-packet length; determine whether the current sub-data packet is a CBTC sub-packet based on the sub-packet number in the attribute information; if it is a CBTC sub-packet, parse the CBTC sub-packet to obtain the corresponding sub-ground information; if it is not a CBTC sub-packet, skip the current sub-data packet, and find the next sub-data packet based on the sub-packet length in the attribute information, and continue parsing the next sub-data packet; after traversing multiple sub-data packets, multiple sub-ground information are obtained, and the multiple sub-ground information are merged into the CBTC ground information.

[0051] A transponder message consists of a header and several sub-data packets. The CTCS master control unit and the CBTC master control unit identify whether a sub-data packet belongs to a CTCS sub-data packet or a CBTC sub-data packet by the sub-packet number, and determine the length of data to be skipped by the sub-packet length, thus accurately finding the next sub-data packet.

[0052] S130. Determine the first main control unit and the second main control unit from the CTCS main control unit and the CBTC main control unit.

[0053] The first main control unit is the main control unit corresponding to the train's departure trend, that is, the main control unit corresponding to the train leaving the jurisdiction area; the second main control unit is the main control unit corresponding to the train's heading trend, that is, the main control unit corresponding to the train entering the jurisdiction area.

[0054] In this embodiment, the second and first main control units can be determined from the CTCS main control unit and the CBTC main control unit based on the train's direction of travel. For example, if the direction of travel is from the CTCS jurisdiction area into the CBTC jurisdiction area, then the CTCS main control unit is designated as the first main control unit, and the CBTC main control unit is designated as the second main control unit; if the direction of travel is from the CBTC jurisdiction area into the CTCS jurisdiction area, then the CBTC main control unit is designated as the first main control unit, and the CTCS main control unit is designated as the second main control unit. In other words, the main control unit corresponding to the jurisdiction area the train is about to leave is the first main control unit, and the main control unit corresponding to the jurisdiction area the train is about to enter is the second main control unit.

[0055] S140. The first ground information corresponding to the first main control unit is parsed to obtain the switching execution command.

[0056] Wherein, if the first master control unit is the CTCS master control unit, then the first ground information is the CTCS ground information; if the first master control unit is the CBTC master control unit, then the first ground information is the CBTC ground information.

[0057] In this embodiment, when the vehicle control handover task is not executed, the first master control unit has vehicle control authority, and the first ground information corresponding to the first master control unit contains the handover execution instruction. This step parses the first ground information to obtain the handover execution instruction.

[0058] In another embodiment, the handover execution command may be included in the transponder message sent by the ground transponder corresponding to the jurisdiction where the train is located before the train enters the shared management area. For example, when the train is about to enter the CBTC management area from the CTCS management area, and the train is still in the CTCS management area, the CTCS transponder sends a CTCS transponder message to the CTCS master control unit. The CTCS transponder message contains a sub-data packet corresponding to the handover execution command. At this time, the handover execution command includes the switching position, such as performing the train control handover task 3km ahead.

[0059] S150: Based on the switching execution command, the vehicle control authority is switched from the first main control unit to the second main control unit to realize the switching task of vehicle control authority between the CTCS main control unit and the CBTC main control unit.

[0060] In this embodiment, when the switching execution command is parsed from the first ground information, the first master control unit switches control of the train to the second master control unit. Afterwards, the first master control unit no longer has control, and the second master control unit gains control, managing the train's travel information. This travel information includes at least the train's speed, road conditions (such as gradient and speed limit), and control curves. The hybrid transponder message includes not only shared area information but also second ground information corresponding to the second master control unit and first ground information corresponding to the first master control unit. The second and first master control units select the information they need from the hybrid transponder message.

[0061] The technical solution provided in this embodiment receives a mixed transponder message sent by a mixed transponder when the train enters the shared area; the CTCS main control unit selects CTCS ground information from the mixed transponder message, and the CBTC main control unit selects CBTC ground information from the mixed transponder message; a first main control unit and a second main control unit are determined from the CTCS main control unit and the CBTC main control unit; the first ground information corresponding to the first main control unit is parsed to obtain a switching execution command; and the train control right is switched from the first main control unit to the second main control unit based on the switching execution command, so as to realize the task of switching the train control right between the CTCS main control unit and the CBTC main control unit. This application establishes a shared management area for CTCS and CBTC at the boundary between the CTCS and CBTC jurisdiction areas. Hybrid transponders containing both CTCS and CBTC ground information are configured within this shared management area. Compared to existing technologies, this reduces the number of transponders required in the shared management area, improves transponder utilization, and lowers construction costs. It also avoids the problem of onboard equipment receiving a large amount of transponder data in a short time due to a large number of transponder groups, which prevents the onboard equipment from processing all the data in a timely manner. When a train enters the shared management area, the onboard equipment receives hybrid transponder messages from the hybrid transponders. The CTCS master control unit and the CBTC master control unit select the necessary information from the hybrid transponder messages. A switching execution command is obtained by parsing the first ground information corresponding to the first master control unit, and then the switching execution command is used to perform the task of switching the train control between the first and second master control units within the shared management area. The CTCS main control unit and CBTC main control unit of this application select the information they need from the mixed transponder messages, are compatible with ground-deployed mixed transponders, support trains to cross CTCS lines and CBTC lines without stopping, can achieve safe cross-line operation, and thus improve the transportation efficiency of trains.

[0062] In a preferred embodiment, when the train enters the shared management area, the transponder information sent by the hybrid transponder includes additional shared management area information. This shared management area information includes at least the start position of the shared management area (i.e., the starting point), the track length within the shared management area, and the direction indicator of the shared management area. After receiving the shared management area information, the onboard equipment calculates the end position of the shared management area (i.e., the termination point) and the train's direction of travel within the shared management area based on the start position and the track length within the shared management area.

[0063] Specifically, the train's travel direction information within the shared management area is determined based on the shared management area information in the mixed transponder message. This includes: obtaining the shared management area direction identifier from the shared management area information; if the shared management area direction identifier is a first preset identifier, the travel direction information is determined to be from the CTCS management area into the CBTC management area; if the shared management area direction identifier is a second preset identifier, the travel direction information is determined to be from the CBTC management area into the CTCS management area. The shared management area direction identifier can be in the form of a preset flag, a preset icon, or preset text, and this embodiment does not limit its form. For example, a preset icon could be CTCS→CBTC or CBTC→CTCS, and a preset flag could be 0 or 1.

[0064] Preferably, when the train enters the shared management area, the process further includes: determining the train's direction of travel within the shared management area based on the hybrid transponder message; generating a direction of travel display command to cause the display component to execute the command and display the direction of travel information; correspondingly, when the train leaves the shared management area, the process further includes: generating a turn-off command to cause the display component to execute the command and turn off the displayed direction of travel information, thereby enabling the display component on the train's human-machine interface to display the train's direction of travel within the shared management area. For example: when the train enters the shared management area from the CTCS jurisdiction area, the display component displays a shared management area direction indicator, such as CTCS→CBTC, indicating that the train is currently in the shared management area; when the train leaves the shared management area and enters the CBTC jurisdiction area, the display component stops displaying the shared management area direction indicator, indicating that the train is no longer in the shared management area. For example, when a train enters a shared management area from the CBTC jurisdiction, the display component shows the direction of the shared management area, such as CBTC→CTCS, indicating that the train is currently in the shared management area; when the train leaves the shared management area and enters the CTCS jurisdiction, the display component stops showing the direction of the shared management area, indicating that the train is not currently in the shared management area.

[0065] The train control method supporting cross-line operation provided in the embodiments of this application is further described below. Figure 3 This is a second flowchart illustrating a train control method supporting cross-line operation, provided as an embodiment of this application. This embodiment optimizes the above embodiments, specifically by providing a detailed explanation of the process by which the CTCS main control unit processes transponder messages.

[0066] See Figure 3 The method in this embodiment includes, but is not limited to, the following steps:

[0067] S210. Determine whether the train's current location is within the CTCS jurisdiction area or a shared area.

[0068] The CTCS master control unit is configured on the train's onboard equipment to manage the train's operation. When the train crosses lines between the ground CTCS jurisdiction area and the CBTC jurisdiction area, or between the CBTC jurisdiction area and the CTCS jurisdiction area, the CTCS master control unit needs to determine whether to receive ground control information sent by the ground equipment based on the train's current location. The ground equipment includes hybrid transponders, CTCS transponders, and CBTC transponders. CTCS transponder groups containing only CTCS information are configured in the CTCS jurisdiction area, CBTC transponder groups containing only CBTC information are configured in the CBTC jurisdiction area, and hybrid transponders containing both CTCS and CBTC ground information are configured in the shared management area.

[0069] In this embodiment of the application, the transponder information receiving unit receives transponder data sent by a hybrid transponder, a CTCS transponder, or a CBTC transponder through a transponder antenna, and processes the transponder data based on a preset data processing method to obtain a transponder message that conforms to the protocol standard. At this time, the CTCS master control unit needs to first determine whether the current location of the train is within the CTCS jurisdiction area or a co-managed area.

[0070] S220. If it is not a CTCS jurisdiction or co-managed area, discard the transponder message.

[0071] In this embodiment of the application, if the CTCS master control unit determines that the current location of the train is not within the CTCS jurisdiction area or the co-management area (i.e., the CBTC jurisdiction area), it indicates that the current CBTC master control unit has the right to control the train. In this case, the CTCS master control unit does not process the transponder data message, i.e., it discards the transponder message.

[0072] When the train is not located within the CTCS jurisdiction area or a shared jurisdiction area (i.e., within the CBTC jurisdiction area), the CBTC master control unit in train control mode uses the CBTC ground information in the transponder messages. If CTCS ground information is detected from the transponder messages, an anomaly alarm is triggered; anomaly alarms include text prompts, text prompts, and braking to a stop. The CTCS master control unit in non-train control mode ignores all transponder messages.

[0073] Furthermore, when the train is not located in the CTCS jurisdiction area or the co-managed area (i.e., located in the CBTC jurisdiction area), the CBTC master control unit processes the CBTC transponder messages sent by the CBTC transponder and performs train control tasks based on the CBTC transponder messages.

[0074] Preferably, when the train is traveling within the CBTC jurisdiction area, the onboard equipment operates at the CBTC level, and the CBTC master control unit parses the CBTC transponder messages to obtain the CBTC ground information sent by the CBTC transponder, thereby monitoring the safe operation of the train.

[0075] S230. If it is a CTCS jurisdiction or co-managed area, the CTCS ground information is selected from the transponder message, and the vehicle control task is performed based on the CTCS ground information.

[0076] In this embodiment of the application, if the CTCS master control unit determines that the current location of the train is within the CTCS jurisdiction area or the co-management area (i.e., not within the CBTC jurisdiction area), the CTCS master control unit is in working state. Then, the CTCS master control unit selects the CTCS ground information from the transponder messages and performs the train control task based on the CTCS ground information.

[0077] S240. When the transponder message contains CBTC ground information, determine whether the train's current location is a shared management area or a CTCS jurisdiction area.

[0078] In this embodiment, when the CBTC master control unit finds the CBTC ground information from the transponder message, it needs to further determine whether the train's current location is a shared management area or a CTCS jurisdiction area. This is because the processing method for CBTC ground information will differ depending on the train's current location.

[0079] S250, if it is a shared management area, then discard the CBTC ground information.

[0080] In this embodiment, if the CTCS master control unit determines that the train's current location is a shared management area, then the CBTC master control unit is also operational. The CBTC master control unit will select CBTC ground information from the transponder messages. Therefore, the CTCS master control unit does not need to process the transponder data messages; it simply discards them. In other words, when the train is listed as being in a shared management area, both the CTCS master control unit and the CBTC master control unit select the information they need from the transponder messages.

[0081] S260. If it is a CTCS jurisdiction, generate a message to indicate an error in message reception.

[0082] In this embodiment of the application, if the CTCS master control unit determines that the current location of the train is within the CTCS jurisdiction area, it indicates that the current CTCS master control unit has the right to control the train. At this time, receiving a transponder message containing CBTC ground information is an abnormal phenomenon. Therefore, the CBTC ground information is discarded, and a prompt message is generated to indicate that the message reception is abnormal.

[0083] When the train is within the CTCS jurisdiction area, the CTCS master control unit in train control mode uses CTCS ground information in the transponder messages. If CBTC ground information is detected from the transponder messages, an anomaly alarm is triggered; anomaly alarms include text prompts, text prompts, and braking to a stop. The CBTC master control unit in non-train control mode ignores all transponder messages.

[0084] Furthermore, when the train is within the CTCS jurisdiction area, the CTCS main control unit receives CTCS transponder messages sent by the CTCS transponder and performs train control tasks based on the CTCS transponder messages.

[0085] Preferably, when the train is traveling within the CTCS jurisdiction area, the on-board equipment operates at the CTCS level, and the CTCS main control unit parses the CTCS transponder messages to obtain the CTCS ground information sent by the CTCS transponder, thereby monitoring the safe operation of the train.

[0086] The technical solution provided in this embodiment determines whether the train's current location is within a CTCS jurisdiction area or a shared area. If it is not within a CTCS jurisdiction area or a shared area, the transponder message is discarded. If it is within a CTCS jurisdiction area or a shared area, CTCS ground information is extracted from the transponder message, and train control tasks are performed based on the CTCS ground information. When the transponder message contains CBTC ground information, it determines whether the train's current location is within a shared area or a CTCS jurisdiction area. If it is within a shared area, the CBTC ground information is discarded. If it is within a CTCS jurisdiction area, a prompt message is generated to indicate an abnormal message reception. This application formulates different transponder message processing strategies based on the different current locations of the train, which can safely ensure the train's cross-line operation and thus improve the train's transportation efficiency.

[0087] It should be noted that the specific process of the CBTC master control unit processing transponder messages is the same as that of the CTCS master control unit, and will not be elaborated here. Specifically, the CBTC master control unit processes transponder messages as follows: It determines whether the train's current location is within a CBTC jurisdiction or a shared jurisdiction; if not, the transponder message is discarded; if it is within a CBTC jurisdiction or a shared jurisdiction, CBTC ground information is extracted from the transponder message, and train control tasks are performed based on this information; when the transponder message contains CTCS ground information, it determines whether the train's current location is within a shared jurisdiction or a CBTC jurisdiction; if it is within a shared jurisdiction, the CTCS ground information is discarded; if it is within a CBTC jurisdiction, a message indicating a message reception error is generated.
