Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0044] The following is combined with Figures 1-6 The present invention describes the train turnaround control system and method.

[0045] Figure 1 This is one of the structural schematic diagrams of the train turnaround control system provided by the present invention, such as... Figure 1 As shown, the present invention provides a train turnaround control system, including: a wireless switch 110, an on-board ATC device 120, and an ATC simulation platform 130.

[0046] The onboard ATC device 120 is connected to the wireless switch 110 and is used to obtain train turnaround information.

[0047] In this embodiment, the turnaround information can indicate that the train is in a turnaround state. When the train is in a turnaround state, the turnaround switching of the on-board ATC device 120 and the ATC simulation platform 130 can be performed. For example, when the on-board ATC device 120 and the ATC simulation platform 130 are located at the front and rear positions of the train, respectively, the turnaround switching of the front and rear can be performed when the train is in a turnaround state.

[0048] The ATC simulation platform 130 communicates with the on-board ATC device 120 via a wireless switch 110. The ATC simulation platform 130 is used to acquire train status data.

[0049] The wireless switch 110 is used to maintain the communication connection between the vehicle-mounted ATC device 120 and the ATC emulation platform 130.

[0050] In this embodiment, the communication connection type can be either a UDP communication connection or a CAN communication connection, that is, the ATC simulation platform 130 exchanges UDP data packets or CAN communication data packets over the network.

[0051] In some embodiments, the ATC simulation platform 130 can be adapted to different head-and-tail communication protocols, such as the UDP communication protocol.

[0052] In this embodiment, the test can be completed by manually modifying the first and last communication verification data packets on the ATC simulation platform 130, which reduces the time required for multiple steps.

[0053] Figure 2 This is the second schematic diagram of the train turnaround control system provided by the present invention. Figure 2 In the embodiment shown, the protocol type of the head-to-tail communication can be modified before the ATC simulation platform 130 is run. When configured for UDP network communication, the ATC simulation platform 130 only needs to be connected to the real ATC cabinet under test through the wireless switch 110 to establish a UDP communication connection. Systems such as ZC (Zone Controller), CI (Computer Interlocking), and ATS (Automatic Train Supervision) are connected to the wireless switch 110.

[0054] In this embodiment, the ATC simulation platform 130 communicates with the vehicle-mounted ATC device 120 via the UDP communication protocol, meeting the requirement of UDP data interaction every 200ms.

[0055] The ATC simulation platform 130 is used to generate turnaround instructions based on turnaround information and status data. The turnaround instructions are used to instruct the on-board ATC device 120 and the ATC simulation platform 130 to perform a turnaround switch.

[0056] In this embodiment, turning back and switching ends refers to the process where, after the train enters the platform and comes to a complete stop, the driver presses the "automatic turn-back" button and manually closes the driver's cab, while the driver at the rear presses the "automatic turn-back" button to start the rear driver's cab, thus completing the cab switching.

[0057] In this embodiment, the data sent by the ATC simulation platform 130 to the vehicle-mounted ATC device 120 includes the ATP start-end communication interface type, sender device ID, receiver device ID, ATP start-end data version verification information, record of the cycle count when sending this message, device communication cycle, record of the other party's message sequence number in the previous message received from the other party, and reply with the cycle count.

[0058] The status data includes the system's current mode (STB; RM (no positioning); RM (with positioning); CM-I; AM-I; CM-C; AM-C; CAM; FAM; EUM), the local driver's cab activation status (activated), MC1 terminal verification results, door permission status, turnaround command, notification to the other end to exit turnaround command, local turnaround status, turnaround confirmation, ground equipment connection status, local operating condition information, local driver's key status, door status loss indicator, remote cut-off command, command to activate the other end's driver's cab, and the connection status of ATP (Automatic Train Protection) and ATO (Automatic Train Operation).

[0059] The train turnaround control system provided in this embodiment of the invention communicates with the on-board ATC device 120 via an ATC simulation platform 130. Based on the train's status data and turnaround information, it performs the turnaround switching between the front and rear ends of the train, thereby enabling the virtual ATC device to replace the real ATC device and communicate with the other end ATC. This reduces the maintenance cost of the on-board equipment, shortens the debugging cycle of the on-board equipment, and improves the train turnaround efficiency.

[0060] In some embodiments, the device further includes: a CAN box, which is electrically connected to the ATC emulation platform 130; and a CAN bus, which is electrically connected to both the CAN box and the vehicle-mounted ATC device 120, and the ATC emulation platform 130 communicates with the vehicle-mounted ATC device 120 via the CAN bus.

[0061] In this embodiment, the ATC simulation platform 130 can realize the head-to-tail communication of the train according to the CAN communication protocol.

[0062] In this embodiment, the CAN box can be electrically connected to the ATC simulation platform via a wired connection or a wireless connection; the wired connection can be made using a twisted pair cable or a terminal block.

[0063] In this embodiment, the CAN bus communication rate is 125kbps.

[0064] Figure 3 This is the third schematic diagram of the train turnaround control system provided by the present invention. Figure 3 In the embodiment shown, the protocol type of the head-to-tail communication is configured as CAN communication through the ATC simulation platform 130, and the ATC simulation platform 130 and the vehicle ATC device 120 are simultaneously connected to the CAN bus through the CAN box to realize the CAN communication connection between the ATC simulation platform 130 and the vehicle ATC device 120.

[0065] The train turnaround control system provided in this embodiment of the invention enables CAN communication between the ATC simulation platform 130 and the on-board ATC device 120 by setting up a CAN box and CAN bus, which increases the types of communication between the head and tail of the train and improves the practicality of the ATC simulation platform 130.

[0066] In some embodiments, the ATC simulation platform 130 includes: a display for displaying communication connection information of the vehicle-mounted ATC device 120 and the ATC simulation platform 130; and a processor for generating turnaround instructions based on turnaround information and status data.

[0067] In this embodiment, the display can show the connection status between the vehicle-mounted ATC device 120 and the ATC simulation platform 130 to determine whether the communication connection between the two is abnormal.

[0068] In this embodiment, the display can also be used to show the train's turnaround status and turnaround instructions. For example, the display screen of the ATC simulation platform 130 can show "Turnaround status valid" or "Turnaround ended".

[0069] In this embodiment, the ATC simulation platform 130 also has a processor for performing logical processing of data and outputting calculation results, and sending the output logical processing instructions to the vehicle-mounted ATC device 120 via UDP communication protocol or CAN communication protocol.

[0070] The train turnaround control system provided in this embodiment of the invention uses a processor to perform logical processing on train status data, generates turnaround commands for automatically controlling the change of ends of the train, and uses the processor of the ATC simulation platform 130 to visualize the transmitted data or data processing results on the display screen, so as to facilitate the control of the train end-changing process by the commands or status messages displayed on the user interface.

[0071] The train turnaround control method provided by the present invention is described below. The train turnaround control method described below can be referred to in correspondence with the train turnaround control system described above.

[0072] Figure 4 This is one of the flowcharts illustrating the train turnaround control method provided by the present invention, such as... Figure 4 As shown, the present invention provides a train turnaround control method, applied to an ATC simulation platform 130, which is communicatively connected to an onboard ATC device 120, and includes the following steps:

[0073] Step 410: Obtain train status data and turnaround information.

[0074] In this embodiment, the ATC simulation platform 130 is connected to the on-board ATC device 120 for communication, and the ATC simulation platform 130 is used to acquire the status data of the train.

[0075] In this embodiment, the ATC simulation platform 130 is connected to the on-board ATC device 120 via a wireless switch 110, and the ATC simulation platform 130 is used to acquire the train's status data.

[0076] In this embodiment, the train's status data includes the system's current mode, the local driver's cab activation status (activated), MC1 terminal verification result, door permission status, turnaround command, notification to the other end to exit turnaround command, local turnaround status, turnaround confirmation, ground equipment connection status, local operating condition information, local driver's key status, door status loss indicator, remote cut-off command, command to activate the other end's driver's cab, and ATP and ATO connection status, etc.

[0077] In this embodiment, the turnaround information can indicate that the train is in a turnaround state. When the train is in a turnaround state, the turnaround switching of the on-board ATC device 120 and the ATC simulation platform 130 can be performed. For example, when the on-board ATC device 120 and the ATC simulation platform 130 are located at the front and rear positions of the train, respectively, the turnaround switching of the front and rear can be performed when the train is in a turnaround state.

[0078] Step 420: Based on the turnaround information and status data, obtain the turnaround command.

[0079] In this step, the turnaround information can indicate that the train is in a turnaround state. When the train is in a turnaround state, the turnaround switching of the on-board ATC device 120 and the ATC simulation platform 130 can be performed. For example, when the on-board ATC device 120 and the ATC simulation platform 130 are located at the front and rear positions of the train, respectively, the turnaround switching of the front and rear can be performed when the train is in a turnaround state.

[0080] In this embodiment, the turnaround command is used to instruct the on-board ATC device 120 and the ATC simulation platform 130 to perform a turnaround switch.

[0081] Step 430: Based on the turnaround command, control the on-board ATC equipment and the ATC simulation platform to perform a turnaround switch.

[0082] In this embodiment, the processor of the ATC simulation platform 130 performs logical processing on the turnaround information and train status data sent by the on-board ATC device 120 to obtain operation instructions for controlling the processors of the ATC simulation platform 130 and the on-board ATC device 120 to switch ends, and sends the operation instructions to the on-board ATC device 120 through the UDP communication protocol or the CAN communication protocol.

[0083] The train turnaround control method provided in this embodiment of the invention uses an ATC simulation platform 130 to communicate with the on-board ATC device 120 at both ends. Based on the train's status data and turnaround information, it performs the turnaround switching between the front and rear ends of the train. This allows the virtual ATC device to replace the real ATC device and communicate with the other end of the ATC device at both ends, reducing the maintenance cost of the on-board equipment, shortening the debugging cycle of the on-board equipment, and improving the train turnaround efficiency.

[0084] In some embodiments, the status data includes activation information and inactivation information, and the turnaround information includes first turnaround information and second turnaround information, wherein the turnaround directions of the first turnaround information and the second turnaround information are opposite; based on the turnaround information and the status data, a turnaround instruction is obtained, including: if it is confirmed that the ATC simulation platform 130 is inactivation and the vehicle-mounted ATC device 120 is activation, determining a turnaround instruction based on the first turnaround information, wherein the turnaround instruction is used to instruct the ATC simulation platform 130 to switch from standby mode to standby mode.

[0085] Figure 5 This is the second flowchart of the train turnaround control method provided by the present invention. Figure 5 In the illustrated embodiment, the ATC simulation platform 130 is connected to the train wireless switch 110 via a network cable. After the head-to-tail information verification is passed, the ATC simulation platform 130 is controlled to send status information packets to simulate normal head-to-tail communication. If it is confirmed that the ATC simulation platform 130 is inactive and the onboard ATC device 120 is active, the following train turnaround and terminal switching are performed:

[0086] (1) In the simulation environment, the train stops accurately and stably on the track with the turnaround attribute. After the ATC at the head end judges that there is no abnormality that prevents the turnaround, the on-board ATC device 120 starts to send the "in turnaround state" information to the ATC simulation platform 130 at the tail end after the automatic turnaround button is pressed at the head end. The turnaround state in the status data packet received on the display interface of the ATC simulation platform 130 is observed to be: the turnaround state is valid. The positioning information packet sent by the on-board ATC device 120 and the valid data frame of the end-switching request can be observed from the ATC simulation platform 130. (2) Under the condition that the on-board ATC device 120 does not enter the standby mode, the ATC simulation platform 130 sends the "activated state" and the on-board ATC device 120 starts to initiate the deregistration to the CI. Then, the ATC simulation platform 130 sends the "end turnaround command" and the on-board ATC device 120 switches to the standby mode. The display interface of the ATC simulation platform 130 shows that the ATC simulation platform 130 has switched to the activated state. The train turnaround and end-switching are completed.

[0087] The train turnaround control method provided in this embodiment of the invention enables the turnaround switching between the ATC simulation platform 130 and the on-board ATC device 120 when the ATC simulation platform 130 is inactive and the on-board ATC device 120 is active. This reduces the number of on-board ATC devices 120 in multi-train formation scenarios and improves the efficiency of train turnaround switching.

[0088] In this embodiment, the status data includes activation information and inactivation information, and the turnaround information includes first turnaround information and second turnaround information, with the turnaround directions of the first turnaround information and the second turnaround information being opposite. Based on the turnaround information and status data, a turnaround command is obtained, which further includes: if it is confirmed that the ATC simulation platform 130 is active and the vehicle-mounted ATC device 120 is inactive, a turnaround command is determined based on the second turnaround information, and the turnaround command is used to instruct the ATC simulation platform 130 to switch from standby mode to standby mode.

[0089] In this embodiment, the ATC simulation platform 130 is connected to the "turnaround CAN" communication interface of the vehicle-mounted ATC device 120 (the real ATC device has not experienced a fault that does not allow turning around and switching ends) via a USB to CAN interface adapter. The parameters of the ATC simulation platform 130 are modified to enable head-to-tail CAN interface communication. After the head-to-tail information verification is passed, the ATC simulation platform 130 is controlled to send status information packets. The normal head-to-tail communication of the ATC can be observed and confirmed on the display interface of the ATC simulation platform 130.

[0090] exist Figure 5 In the illustrated embodiment, if it is confirmed that the ATC simulation platform 130 is active and the on-board ATC device 120 is inactive, the following train turnaround and end-to-end switching is performed:

[0091] (1) Modify the train's location to the turnaround track through the display interface of the ATC simulation platform 130, and send the train's location to the onboard ATC device 120. Then send the "in turnaround state" information to the onboard ATC device 120 at the tail end. After receiving the end-to-end request and positioning information from the ATC simulation platform 130 at the head end, the onboard ATC device 120 lights up the tail end AR light. (2) The ATC simulation platform 130 at the head end displays the confirmation information sent by the onboard ATC device 120. At the same time, the onboard ATC device 120 initiates registration with ZC. (3) Activate the onboard ATC device 120. The display interface of the ATC simulation platform 130 displays that the tail end onboard ATC device 120 has been activated and the tail end onboard ATC device 120 has registered. (4) When the user presses the turnaround button on the onboard ATC device 120, he can observe the "end turnaround" command received on the display interface of the ATC simulation platform 130. The train turnaround end-to-end is completed.

[0092] The train turnaround control method provided in this embodiment of the invention enables the turnaround switching between the ATC simulation platform 130 and the on-board ATC device 120 when the ATC simulation platform 130 is active and the on-board ATC device 120 is inactive, thereby reducing the number of on-board ATC devices 120 in multi-train formation scenarios and improving the efficiency of train turnaround switching.

[0093] In some embodiments, before acquiring train status data and turnaround information, the method further includes: sending verification data to the on-board ATC device 120, the verification data being used to acquire abnormal status of the on-board ATC device 120.

[0094] In this embodiment, after the ATC simulation platform 130 establishes head-to-tail communication with the on-board ATC device 120 as the activation end, it sends verification data to the on-board ATC device 120 to check the communication status. The head-to-tail communication status (connected or not connected) of the train can be observed on the display interface of the ATC simulation platform 130.

[0095] In this embodiment, the verification data sent by the ATC simulation platform 130 to the on-board ATC device 120 includes: train set number, MC2 terminal VID verification status, local ATP self-test result, local ATO self-test result, local ATP fault status, local ATO fault status, local BTM fault status, local MMI fault status, local radar fault status, local speed transmission 1 fault status, local speed transmission 2 fault status, local AOM fault status, local DCS fault status, and local ATO station stop time.

[0096] In some embodiments, the contents of the system status data packets and verification data packets sent by the ATC simulation platform 130 can be manually modified and saved on the software interface, which facilitates testing the real ATC's response when various verification information is inconsistent.

[0097] The train turnaround control method provided in this embodiment of the invention reduces testing procedures, saves testing time, and improves the efficiency of train turnaround by sending verification data to the on-board ATC device 120 before acquiring train status data and turnaround information, and by using the ATC simulation platform 130 to modify the head and tail communication verification data packets.
