Description

Technical Field

[0001] The present disclosure relates to the field of rail transit technology, and in particular to a method, system, device and medium for communication between a sleep-wake-up unit and the ground. Background Art

[0002] In the field of urban rail transit, compared with the communication-based automatic train control system (CBTC), train automatic sleep, train automatic wake-up, and train sleep supervision are the core functions of fully automatic driving operation (FAO). In order to efficiently realize these functions, the vehicle-mounted equipment (VOBC) adds an auxiliary driving control unit (AOM) as a supplement. The auxiliary driving control unit is connected to the ATS to receive sleep wake-up commands and feedback the sleep status.

[0003] In the field of intercity railways and high-speed railways, the CTCS train control system is adopted, and CTCS-2+ATO is the main development direction of intercity railway automated operation. CTCS-2+ATO belongs to the GoA2 level, that is, semi-automatic train operation. In order to improve the automation level and realize fully automatic unmanned driving, the CTCS-2+ATO on-board signal equipment adds a dormant awakening unit (DAU) to realize the remote dormant awakening function of the train. Since the CTCS-2+ATO system and the FAO system are very different in structural design, the communication between the dormant awakening unit and the ground is also very different.

[0004] With the existing technology, there is no practical application of the sleep wake-up unit in the CTCS-2+ATO train control system, so there is no communication solution between it and the ground.

[0005] In summary, there is an urgent need for a solution to the communication between the CTCS-2+ATO sleep wake-up unit and the ground. Summary of the invention

[0006] In view of the above problems, the present disclosure provides a method, system, device and medium for communication between a sleep and wake-up unit and the ground, which are used to solve the problem of communication between a CTCS-2+ATO sleep and wake-up unit and the ground.

[0007] In a first aspect, a method for communication between a sleep-wake-up unit and a ground surface is provided, the method comprising: The sleep-wake-up unit receives the TSRS device information and connection command sent by the vehicle-mounted ATO device; According to the connection command, the sleep-wake-up unit initiates a connection with the TSRS device to establish a session; After the sleep-wake-up unit establishes a session with the TSRS device, the sleep-wake-up unit forwards the M136 message with the location report to the dispatch center through the TSRS device; The sleep-wake-up unit receives the sleep-wake-up command issued by the dispatch center through the TSRS device, and feeds back the sleep-wake-up status to the dispatch center.

[0008] Further, the sleep wake-up unit receives the TSRS device information and connection command sent by the vehicle-mounted ATO device, and then also includes: According to the connection command, the sleep-wake-up unit disconnects from the TSRS device.

[0009] Furthermore, the sleep-wake-up unit initiates a connection with the TSRS device, including: After receiving the TSRS device ID, IP address and connection establishment command sent by the vehicle-mounted ATO device, the sleep-wake-up unit uses a device number different from the vehicle-mounted ATO device to call the TSRS device and establish a communication request; When the TSRS device determines that the device currently requesting connection is a sleep awakening unit according to the received device number, the sleep awakening unit establishes a connection with the TSRS device and registers in the TSRS device.

[0010] Furthermore, it also includes: After the sleep awakening unit establishes a communication session with the TSRS device, when receiving new TSRS device information and a connection establishment command sent by the vehicle-mounted ATO device, the sleep awakening unit sends a session termination request to the connected TSRS device.

[0011] Furthermore, it also includes: After the sleep-wake-up unit establishes a communication session with the TSRS device, when receiving a disconnection command sent by the vehicle-mounted ATO device, the sleep-wake-up unit initiates a session termination request to the connected TSRS device.

[0012] Furthermore, it also includes: After the onboard equipment is powered on, the onboard ATO equipment establishes a connection with the TSRS equipment, and sends TSRS equipment information and a connection establishment command to the sleep wake-up unit. The sleep wake-up unit establishes a connection with the TSRS equipment. When the train is running, the sleep wake-up unit and the onboard ATO equipment both maintain a connection with the TSRS equipment at the same time. When the on-board ATO device is crossing the jurisdiction of the TSRS device, when it receives the TSRS device information of the next jurisdiction in the CTCS-12 package of the ground transponder, it forwards it to the sleep wake-up unit and sends a connection establishment command. After the sleep wake-up unit initiates and confirms the end of the session with the currently connected TSRS device, it establishes a connection with the newly received TSRS device until the train ends its operation and the on-board ATO device is disconnected from the TSRS device. The sleep wake-up unit maintains communication with the TSRS device in the jurisdiction of the storage line, receives sleep or wake-up commands and feedbacks the status.

[0013] Furthermore, it also includes: After the vehicle-mounted device is powered on, the vehicle-mounted ATO device establishes a connection with the TSRS device, and the sleep wake-up unit does not establish a connection with the TSRS device; During the mainline operation, the sleep-wake-up unit is not connected to the TSRS device. After the train stops in a specific area after the operation is completed, the on-board ATO device sends the TSRS device information and connection establishment command to the sleep-wake-up unit. The sleep-wake-up unit establishes a communication session with the TSRS device and receives the sleep-wake-up command issued by the dispatching center. After waking up from sleep mode, the vehicle-mounted ATO device successfully establishes a connection with the TSRS device and sends a disconnect command to the sleep wake-up unit, and the sleep wake-up unit actively disconnects from the TSRS device.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] A method for communicating between a sleep and wake-up unit and a ground, the method comprising: The sleep-wake-up unit receives the TSRS device information and connection command sent by the vehicle-mounted ATO device; According to the connection command, the sleep-wake-up unit initiates a connection with the TSRS device to establish a session; After the sleep-wake-up unit establishes a session with the TSRS device, the sleep-wake-up unit forwards the M136 message with the location report to the dispatch center through the TSRS device; The sleep-wake-up unit receives the sleep-wake-up command issued by the dispatch center through the TSRS device, and feeds back the sleep-wake-up status to the dispatch center.

[0024] The specific implementation is as follows: The connection between the sleep wake-up unit and TSRS is controlled by the on-board ATO device. The on-board ATO device sends the TSRS device information that needs to be connected to the sleep wake-up unit to the sleep wake-up unit, and sends a connection command. The sleep wake-up unit receives the TSRS information sent by the on-board ATO device and initiates or disconnects the connection with TSRS according to the connection command. The basic process of communication between the sleep wake-up unit and TSRS is as follows: like Figure 1 As shown, after the sleep wake-up unit receives the TSRS ID, IP address and connection establishment command sent by the vehicle-mounted ATO device, it uses a device number different from the vehicle-mounted ATO device to call TSRS and establish a communication request. TSRS should be able to determine that the current device requesting connection is the sleep wake-up unit based on the device number, and establish a connection with the sleep wake-up unit and register the device. The sleep wake-up unit does not need to go through the SOM process to establish a communication session with TSRS.

[0025] like Figure 2 As shown, after the sleep awakening unit establishes a session with TSRS, it should send an M136 message with a location report to TSRS, and TSRS forwards it to the dispatch center. The sleep awakening unit can receive the sleep awakening command issued by the dispatch center and feed back the sleep awakening status to the dispatch center.

[0026] like Figure 3As shown, after the sleep-wake-up unit establishes a communication session with the TSRS, if it receives new TSRS information and a connection establishment command sent by the vehicle-mounted ATO device, the sleep-wake-up unit sends a request to end the session to the connected TSRS. If it receives a disconnection command sent by the vehicle-mounted ATO device, the sleep-wake-up unit initiates a request to end the session to the connected TSRS.

[0027] Since the sleep wake-up unit and TSRS are connected to exchange sleep wake-up commands and sleep wake-up states, there are two ways for the vehicle ATO device to control the sleep wake-up unit and TSRS to connect: like Figure 4 As shown, the sleep wake-up unit is continuously connected to TSRS. The onboard equipment is powered on, the driver enters the TSRS information on the DMI, the onboard ATO equipment establishes a connection with the TSRS, and sends the TSRS information and connection establishment command to the sleep wake-up unit. The sleep wake-up unit establishes a connection with the TSRS. When the train is running, the sleep wake-up unit and the onboard ATO equipment both maintain a connection with the TSRS at the same time. This solution requires that when the onboard ATO equipment crosses the TSRS jurisdiction, when it receives the TSRS information of the next jurisdiction in the CTCS-12 package of the ground transponder, it forwards it to the sleep wake-up unit and sends a connection establishment command. After the sleep wake-up unit initiates and confirms the end of the session with the currently connected TSRS, it establishes a connection with the newly received TSRS until the train ends operation. The onboard ATO equipment is disconnected from the TSRS. The sleep wake-up unit maintains communication with the TSRS that governs the storage line range, receives sleep / wake-up commands and feedbacks the status.

[0028] In this method, the sleep and wake-up unit can maintain real-time connection with the ground, and the dispatch center can issue instructions to the train sleep and wake-up unit at any time, so as to realize the function of train sleep or wake-up on the main line. However, due to the limited number of TSRS-controlled equipment, the sleep and wake-up unit maintaining connection with TSRS will reduce the number of trains under the control of TSRS on the main line.

[0029] like Figure 5 As shown, the sleep-wake unit is connected to TSRS only in a specific area. After the on-board equipment is powered on, the on-board ATO equipment establishes a connection with TSRS, and the sleep wake-up unit does not establish a connection with TSRS. During the mainline operation, the sleep wake-up unit is not connected to TSRS. After the train completes the operation and stops in a specific area (such as the sleep wake-up window), the on-board ATO equipment sends TSRS information and a connection establishment command to the sleep wake-up unit. The sleep wake-up unit establishes a communication session with TSRS and accepts the sleep wake-up instruction issued by the dispatch center. After waking up from sleep, the on-board ATO equipment successfully establishes a connection with TSRS, and sends a disconnection command to the sleep wake-up unit, and the sleep wake-up unit actively disconnects from TSRS.

[0030] In general, trains only sleep or wake up in the storage line of the EMU depot / station, and rarely perform remote sleep and wake-up functions on the main line. Therefore, this method designs the sleep and wake-up unit to establish a connection with TSRS only in a specific area and accept the sleep and wake-up command from the dispatch center. When the train is operating on the main line, the sleep and wake-up unit is not connected to TSRS, which increases the ability of TSRS on the main line to manage vehicles and reduces the pressure on its data interaction.

[0031] To realize the remote sleep and wake-up function under the CTCS system, the sleep and wake-up unit must communicate with the ground equipment. The communication between the auxiliary driving unit and the ground automatic train monitoring system (ATS) described in the second part is only applicable to the urban rail transit FAO system, not to the CTCS system. The communication connection between the on-board ATO equipment and TSRS described in the second part can only support the existing functions of the on-board ATO system, such as the interaction of line data and plan information, and cannot realize the sleep and wake-up function.

[0032] Aiming at the train-ground communication requirements for realizing the remote sleep and wake-up function under the CTCS standard, the present invention proposes the process of establishing, interacting and terminating the session between the sleep and wake-up unit and the TSRS, and proposes two solutions for the on-board ATO equipment to control the connection between the sleep and wake-up unit and the TSRS. Solution 1 satisfies the execution of the sleep and wake-up function on the entire line, and solution 2 satisfies the execution of the sleep and wake-up function in a specific area of ​​the train. The control method can be selected according to different scenarios.

[0033] The present invention discloses a process for establishing a session between a sleep wake-up unit and TSRS: a simplified handshake process is used to establish a session with TSRS. The process for interacting with the sleep wake-up unit and TSRS session: TSRS sends a sleep wake-up command to the sleep wake-up unit, and the sleep wake-up unit feeds back the sleep wake-up status. The process for ending the session between the sleep wake-up unit and TSRS: M156 is used to initiate the end of the session, and M39 is received to confirm the end of the session. There are two schemes for the on-board ATO device to control the connection between the sleep wake-up unit and TSRS: the sleep wake-up unit is continuously connected to TSRS and the sleep wake-up unit is only connected to TSRS in a specific area.

[0034] The vehicle-mounted ATO device of the present invention controls the sleep-wake-up unit to be connected to the TSRS and can be replaced by other vehicle-mounted devices that control the sleep-wake-up unit to be connected to the TSRS (such as a vehicle-mounted ATP device).
