Problems solved by technology

[0003] At present, after the catenary is powered off, the electric inspection method is manually operated, that is, before the electric inspection, it is necessary to manually check the electric pole once, and after the catenary isolating switch is opened and the power is cut off, the operator will check Lift the electric pole along the direction of the track, use the metal head of the electric pole to touch and close to the catenary for three times of electric inspection, and confirm that there is no sound and light alarm on the electric pole, indicating that there is no electricity (if there is sound, light and sound signal, it means that there is still electricity) , but the voltage level cannot be judged, and the ground crew driver needs to raise the bow to detect the voltage)
[0004] This traditional electric inspection method completely relies on manual work, which is labor-intensive and low in efficiency, which greatly restricts the development of electric bus repair and maintenance in the direction of mechanization, automation, and intelligent control. The reason for requiring three electric inspections is that Human error causes missed inspection, which has certain safety hazards and is not conducive to safe production
