Technical Field

[0001] The present invention relates to the technical field of high - speed railway train operation control, and more specifically, to an automatic shunting system and method for a motor car depot / motor car shed. Background Art

[0002] At present, as an important supporting facility for high - speed railways, the motor car depot / motor car shed is an important place for the maintenance, first - and second - level inspections, storage, and emergency repairs of EMUs, and is the key to ensuring the safe, punctual, and efficient operation of EMUs.

[0003] However, due to the particularity of the entry and exit times and maintenance times of EMUs in the motor car shed, the driver's duty mainly focuses on early morning at night, with heavy workload, poor working environment, and easy fatigue. For the main driver, the main responsibility is to board the train at the storage line in the motor car shed, manually drive the EMU onto the line, and after the on - line task is completed, drive the EMU back to the storage line in the motor car shed; for the ground crew driver, the main responsibility is to move the EMU for shunting, such as entering and leaving the depot, turning around the line, etc. Every day when boarding the train, a large amount of time is required to walk back and forth between different line areas and different driving ends in the station yard to meet the shunting and maintenance requirements. This situation not only poses potential safety hazards but also reduces work efficiency.

[0004] Therefore, how to propose an automatic shunting system and method for a motor car depot / motor car shed to achieve remote shunting and unmanned shunting, reduce the labor intensity of drivers, and improve the operation efficiency of the motor car depot / motor car shed is an urgent problem to be solved by those skilled in the art.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] On the one hand, the present invention discloses an automatic shunting system for a multiple unit depot / multiple unit station, as Figure 1 shown, including ground equipment, on-vehicle equipment and peripheral equipment;

[0036] The ground equipment includes a CCS, a TSRS, a remote driving cab, and a remote control server connected in sequence;

[0037] The on-vehicle equipment includes an ATP unit, an ATO unit, a remote control unit, a sleep / wake-up unit, and an environment perception unit; the ATP unit, the remote control unit, the sleep / wake-up unit, and the environment perception unit are all connected to the ATO unit, and the ATO unit and the sleep / wake-up unit perform information interaction with the TSRS through a radio station; the remote control unit is simultaneously connected to the remote control server and the environment perception unit;

[0038] The peripheral equipment feeds back the real-time status data of the train to the on-vehicle equipment.

[0039] The CCS sends train sleep / wake-up commands, configuration data, and shunting plans to the corresponding on-vehicle equipment through the TSRS according to the operation plan; an interface with the remote control server is added to send the shunting plan to the remote control server.

[0040] The TSRS forwards the sleep / wake-up commands, configuration data, and shunting plans from the CCS to the on-vehicle equipment, and at the same time forwards the operation status information from the on-vehicle equipment to the CCS.

[0041] The remote control server is used to implement the pairing management function of multiple multiple units and the remote driving cab.

[0042] The remote driving cab realizes the function of remote driving, displays the train operation status, on-vehicle equipment status, and line status sent by the on-vehicle remote control unit of the selected multiple unit in real time, and sends the train control instructions of the ground driver to the remote control unit.

[0043] The sleep / wake-up unit is used to achieve the automatic sleep / wake-up of the multiple unit train. Specifically, it executes the sleep / wake-up command from the CCS, notifies the vehicle for self-check, reports the vehicle self-check result to the CCS, notifies the vehicle to perform static tests and dynamic tests, and reports the test results to the CCS. It forwards the SoM data such as the train number from the CCS to the ATP / ATO for the ATP automatic SoM process. The sleep / wake-up unit always remains powered on and shares the wireless channel with the ATO to the TSRS.

[0044] The environment perception unit is equipped with sensors such as cameras and lidar to obtain environment perception information, has the function of identifying pedestrians and obstacles, and sends the video / image processing and recognition results to the ATO unit.

[0045] The ATO has functions such as automatic train departure, controlling the train according to the environment perception information and the instructions of the remote control unit. After the ATO is powered off, the sleep / wake-up unit still remains connected to the TSRS.

[0046] On the other hand, the present invention also discloses an automatic shunting method for a multiple unit depot or a multiple unit shed, which is applied to the above-mentioned automatic shunting system for a multiple unit depot or a multiple unit shed. Refer to Figure 2 and the method includes the following steps:

[0047] S1. The CCS remotely sends a wake-up command to the train automatically or manually according to the train schedule. Test steps are respectively executed at both ends of the train. After passing the tests at both ends, the on-vehicle enters the standby working condition and feeds back to the CCS.

[0048] In this embodiment, the CCS remotely sends a wake-up command to the train automatically or manually according to the train schedule, or the whole vehicle is powered on at low voltage by manually pressing the train power switch.

[0049] The test steps include power-on self-check, static test, and dynamic test.

[0050] After powering on at low voltage, the system performs equipment power-on self-check, including vehicle self-check and signal self-check. The vehicle self-check is completed by the vehicle system, and the on-vehicle equipment feeds back the vehicle self-check result to the CCS. The signal self-check refers to the on-vehicle equipment self-checking its own boards, vehicle-ground communication, etc., and feeding back the self-check results to the CCS.

[0051] The on-vehicle equipment controls the vehicle to perform static tests, including high-voltage power-on, braking system, lighting, doors, train broadcasting, etc., and feeds back the test results to the CCS.

[0052] For the dynamic test, the on-vehicle equipment outputs a jump signal to the vehicle, and the vehicle controls the train to run at a low speed for a predefined distance to confirm that the train control interfaces and functions of the on-vehicle system and the vehicle system are normal.

[0053] S2.CCS formulates the dispatching and operation plan according to the vehicle demand, automatically triggers the processing of the outbound train route, and drives out of the EMU depot / EMU depot, including:

[0054] 1) CCS formulates dispatching and operation plans according to vehicle demand, and automatically triggers the processing of outbound train routes at a specified time (configurable) in advance.

[0055] 2) After the on-board equipment receives the authorization from CCS allowing the train to operate in fully automatic mode, it prepares to automatically start the train in PS mode based on the ground permission code.

[0056] 3) The on-board equipment controls the train to automatically run after receiving the transponder information arranged on the ground, and then upgrades to FAM mode to control the train.

[0057] 4) The driver confirms the departure. The driver turns on the key and manually upgrades the FAM mode according to the process and presses the confirmation button to start the vehicle.

[0058] S3.CCS automatically assigns train numbers to trains running from the moving vehicle base to the moving line / storage line according to the planned operation diagram, and automatically sends mainline service condition instructions to the trains.

[0059] After receiving the mainline service operating condition instruction, the on-board equipment sends the operating condition instruction to the vehicle TCMS, and the vehicle TCMS controls the lighting, air conditioning or electric heating to turn on.

[0060] S4. After CCS checks according to the planned operation diagram that the train that has completed the current planned task has completely entered the storage line, it will automatically set the train to exit the mainline service car and send a stop mainline service instruction to the train.

[0061] After receiving the command to stop mainline service, the on-board equipment sends a command to stop mainline service condition to the vehicle. The vehicle will take into account energy saving and section operation needs and turn off some lighting, air conditioning or ventilation.

[0062] S5.CCS automatically or manually triggers the return route to the EMU depot / EMU depot according to the return plan. After the route is established, the train is assigned movement authorization;

[0063] After the on-board equipment receives the movement authorization and meets the departure conditions, it starts the train and automatically runs to the storage line to stop and prepare for sleep;

[0064] When a train enters a moving track or a moving vehicle base, the onboard equipment should automatically send a whistle command to the vehicle TCMS.

[0065] S6. The train stops at the designated sleep position according to the timetable. The CCS sends a sleep command to the train remotely, automatically or manually according to the timetable, or the train power switch is manually pressed to execute sleep.

[0066] After the on-vehicle equipment determines that the sleep condition is met, it automatically cancels the direction and driver's cab activation commands, and sends a sleep request to the vehicle. After the vehicle cuts off the high-voltage load, it sends a sleep confirmation to the on-vehicle equipment.

[0067] After receiving the vehicle sleep confirmation, the on-vehicle equipment memorizes the sleep position and sends a sleep command to the vehicle. After receiving the sleep command, the vehicle is responsible for powering off the whole vehicle, and the on-vehicle equipment feeds back the sleep state to the CCS.

[0068] Preferably, after the EMU is received into the depot and enters the storage line, remote shunting can be carried out.

[0069] The EMU is connected to the ground remote server in a 5G communication manner through the remote control unit to achieve remote pairing. After the authentication is passed, the EMU is incorporated into the controlled management train set;

[0070] For the EMU to be shunted and moved, the ground ground crew driver finds the designated EMU from the controlled management train set and inputs the authorization command to take over the designated EMU;

[0071] Collect vehicle status, on-vehicle equipment display, front window and cab monitoring information, and transmit it to the remote control server through 5G. After decoding on the ground, it is displayed on the console, and the position of the EMU is located in real time by combining on-vehicle information and CCS tracking position information;

[0072] The ground ground crew driver controls the EMU to move remotely by operating the console according to the current position, vehicle status and front window information. The specific method is to send the train control command to the EMU through 5G.

[0073] Preferably, after the EMU is received into the depot and enters the storage line, automatic shunting can be carried out. The CCS forwards the shunting plan to the on-vehicle equipment through the TSRS and arranges the route;

[0074] The ATO unit controls the EMU to automatically run to the designated position according to the shunting plan.

[0075] It should be noted that remote shunting is a backup redundancy function of automatic shunting.
