Description

Technical Field

[0001] The present invention relates to the technical field of high-speed maglev control, and in particular to a medium- and high-speed maglev operation control system and method centered on vehicle-mounted equipment. Background Art

[0002] During the operation of high-speed maglev trains, the operation, protection, traction, positioning, etc. of the trains are usually controlled according to the zoning control system; and the zoning control system installed on the ground is the core equipment for controlling the safe operation of the maglev trains, and it is distributed in a one-to-one correspondence with the traction substation zoning; for high-speed maglev trains on medium and long trunk lines, in order to facilitate testing, decomposition and reorganization, its zoning control system usually adopts a decentralized structure, but this operation mode is limited to demonstration lines with shorter lines or lines used for functional tests. For high-speed maglev trains on long and long lines, a large number of zoning control systems need to be set up on the ground. Not only is the initial construction cost high, but the workload of on-site repair and maintenance in the later stage is also large, and the maintenance efficiency and economic benefits are low throughout the life cycle.

[0003] In response to the above problems, the prior art patent application number CN202011463715.2 discloses an operation control method, device and electronic equipment for a high-speed maglev train, including a central operation control system, a partition operation control system and an on-board operation control. The central control system mainly completes the operation and display of the system, and automatically issues commands such as setting route instructions to the partition control system according to the timetable. Manual intervention is necessary under certain operating conditions. The partition control system completes functions such as route protection, turnout protection, traction control, traction safety cut-off and minimum speed protection curve. The on-board control system calculates the maximum speed curve and protects the train from speeding. The traction control system completes the ATO curve calculation and is controlled by the partition control system.

[0004] However, in the above method, the longer the line is, the more partition devices there are and the higher the cost is. At the same time, the communication between adjacent partitions is complicated, which can easily cause information blockage. Summary of the invention

[0012] The present invention also provides a medium- and high-speed maglev operation control method centered on vehicle-mounted equipment, which is applied to the medium- and high-speed maglev operation control system centered on vehicle-mounted equipment as described above.

[0013] The steps include:

[0014] Step 1: First, the central operation control system and the vehicle operation control subsystem complete initialization, and detect that the radio transmission between the central operation control system and the vehicle operation control subsystem has been successfully connected and maintains normal communication;

[0019] Step 6: The zoned traction control module completes the handover work with the corresponding external traction control system and the external traction control system of the next section according to the train position to ensure the normal operation of the train;

[0020] Step 7. Repeat steps 4 to 6 until the train reaches the destination according to the planned route.

[0021] Among them, in step three, if the planned arrangement route includes a switch section, the zone switch control module communicates with the switch controller through radio transmission according to the position of the train and completes the corresponding switch movement to the target position and locking.
