When the lifting platform board 410 is in a completely ascending state, the lifting platform board 410 should be in a plane where the inspection platform 100 is located. The standard that the lifting platform board 410 is in the complete descending state is that the plane where the lifting platform board 410 is located and the plane where the inspection groove 300 is located are the same plane. It should be noted that the lifting platform plate 410 only has two states of completely ascending and completely descending, and does not stay in the middle part. The lifting platform plate 410 is an insulating plate, and the material of the insulating plate may be an inorganic insulating material, an organic insulating material or a mixed insulating material.

The alarm unit 22 is electrically connected to the system control dispatcher 30 and is used for giving an alarm to remind the inspection equipment, the inspection personnel or the rail transit rolling stock operation and maintenance system 10 of stopping operation.

Specifically, the system control scheduler 21 receives feedback information of the work condition field detection result. If the field working condition meets the working condition, the system control scheduler 21 sends out a starting signal or an enabling signal of the working. The elevator control module 20 receives an activation signal or an enable signal from the system control scheduler 21. The elevator control module 20 activates the action executing unit 23 to control the driving device 420 to be activated. And if the field working condition does not meet the operation condition, the system control scheduler 21 sends out an operation prohibition signal or an alarm signal. The elevator control module 20 receives a disable signal or an alarm signal from the system control scheduler 21. The elevator control module 20 activates the alarm unit 22. The alarm unit 22 sends out an alarm signal to prompt field workers that the current working condition does not meet the working condition, and the lifting device 10 does not perform corresponding ascending and descending actions. When a device is parked on the surface of the lifting platform plate 410, the distance sensor 430 detects a device parking signal and feeds back the detection result to the system control dispatcher 21. And the system control scheduler 21 receives the equipment stop signal and sends a corresponding instruction by combining the detection result of the field working condition. If the field working condition meets the working condition and the surface of the lifting platform plate 410 is stopped by equipment, the action execution unit 23 controls the driving device 420 to be opened, and the driving device 420 controls the lifting platform plate 410 to ascend or descend. If the field working condition does not meet the operation condition, when the surface of the lifting platform plate 410 stops, the alarm unit 22 still sends out an alarm signal to prohibit operation.
