Before the train leaves the station, the train driver manually controls the pantograph of the train to descend, the train is started to leave the station, the train arrival detection device on the station site sends a train leaving signal to the station power monitoring system, the station power monitoring system separates a station charging device switch, at the moment, the station power supply arm is not electrified, and the charging process in the train station is finished. When the train arrival detection device fails, a train driver contacts a control center dispatcher to remotely and manually adjust the charging device, and the charging process is completed.
In the prior art, the station is generally designed as an open platform, the power supply arm is suspended above the platform rail, and from the perspective of operation and maintenance safety, electrification is allowed only in the train charging process, so that the train arrival detection device is required to provide train arrival and departure signals, and then the switch of the charging device is adjusted to stop and transmit power to the station power supply arm. Under the condition that a circuit is shut down, the charging device is set to be in a dormant state, and a switch of the charging device cannot be closed in the dormant state; before the line starts to operate, the charging device is set to be in an awake state, and a switch of the charging device can be adjusted according to a train station entering and exiting signal in the awake state to stop power transmission for the station power supply arm.

1. Most stations of the charging type rail transit line are ground open platforms, a train arrival detection device is easily interfered by electromagnetic interference sources, social vehicles, pedestrians and other foreign matters, the probability of false triggering of a switch of the charging device is relatively high, and unnecessary equipment loss and accident risks are caused.
2. The station of chargeable track traffic route need set up train arrival detection device in the construction in-process to bury corresponding pipeline and cable, station electric power monitored control system need set up corresponding acquisition point, and carry out the joint debugging of vehicle and ground, need throw in certain equipment material cost, construction cost, debugging cooperation cost, raised this function engineering implementation cost.
