1. A traction cut-off control method for a high-speed magnetic levitation system, which is characterized in that the high-speed magnetic levitation system at least comprises a traction system, a subarea traction cut-off computer and a subarea safety control computer, and the method comprises the following steps:

providing five states for the zone traction cut-off computer, the five states being: "start state", "safe cut-off state", "run state", "traction under test state", "interrupt state";

the partition traction cut-off computer performs state transition among five states according to the command of the partition safety control computer, wherein the state transition is performed as follows:

when the partition traction cut-off computer is started or the communication with the partition safety control computer is interrupted, the partition traction cut-off computer is in a starting state; if the subarea traction cut-off computer receives a starting and releasing command of the subarea safety control computer, the subarea traction cut-off computer is switched to a safety cut-off state;

if the partition traction cut-off computer is in a safe cut-off state and a traction system release command of the partition safety control computer is received, the partition traction cut-off computer is switched to a running state;

if the safe traction cut-off request of the subarea safety control computer is received when the subarea traction cut-off computer is in a running state, the subarea traction cut-off computer is switched to a safe cut-off state;

if the sub-area traction cutting-off computer is transferred to a safe cutting-off state, judging that the number of times of entering the safe cutting-off state within preset time exceeds a preset value, and transferring the sub-area traction cutting-off computer to an interruption state;

if the partition traction cut-off computer is in an interrupt state, receiving a command of canceling the interrupt of the partition safety control computer, and turning the partition traction cut-off computer to a safety cut-off state;

if the partition traction cut-off computer is in a running state, receiving a traction test command of the partition safety control computer, and then switching the partition traction cut-off computer to a traction testing state;

when the partitioned traction cut-off computer is in a traction testing state, one-time traction cut-off can be executed, whether the traction cut-off can be correctly executed or not is judged, the working state of the external equipment is judged, if the external equipment works normally and the traction cut-off is executed without problems, the test is finished, and the partitioned traction cut-off computer is transferred to a safe cut-off state.

2. The traction turn-off control method for a high-speed magnetic levitation system as recited in claim 1, further comprising the steps of:

the subarea traction cut-off computer analyzes the command received from the subarea safety control computer, judges whether the state switching command is correct and feasible, and if the command received by the subarea traction cut-off computer is wrong or not accordant with the state of the subarea traction cut-off computer or the command is not feasible, the subarea traction cut-off computer sends a warning message to the subarea safety control computer and sends an event record to the subarea maintenance computer; if the command received by the zone traction cut-off computer is feasible, the zone traction cut-off computer will prepare to switch states.

3. The traction turn-off control method for a high-speed magnetic levitation system as recited in claim 1, further comprising the steps of:

and after the state conversion of the partition traction cut-off computer is finished, reporting to the partition safety control computer.

4. The traction cut-off control method for the high-speed magnetic levitation system as recited in claim 1, wherein when the zonal traction cut-off computer traction test is completed, a safe cut-off state is entered instead of a running state, so as to ensure the reliability of traction cut-off.

5. The method as claimed in claim 1, wherein the start-up state represents a state when the zone traction cut-off computer is started up, and the traction system is in a safe cut-off state.

6. The traction turn-off control method for a high-speed magnetic levitation system as recited in claim 1, wherein the safe turn-off state comprises that the traction system is in a safe turn-off state.

7. The traction turn-off control method for a high-speed magnetic levitation system as recited in claim 1, wherein the interrupted state indicates that the traction system is in a safe turn-off state.

8. The traction cut-off control method for the high-speed magnetic levitation system as recited in claim 1, wherein the operation state indicates that the traction system is released, and all switches of the traction system are closed at the moment, so as to supply power to the magnetic levitation train according to the operation requirement.

9. The method as claimed in claim 1, wherein the traction-on-test indicates that the traction system is under test, and the partitioned traction-off computer tests the traction-off and peripheral devices.
