In the engineering case of the prior art, the station charging arm is fixedly suspended above a track corresponding to a platform area, when a train enters a designated area (generally, the platform area) of the station, a train arrival detection device on the site of the station sends a train arrival signal to a station electric power monitoring system, the station electric power monitoring system closes a switch of the station charging device, the station power supply arm is electrified at the moment, a train driver manually controls a pantograph of the lifted train to be attached to the station power supply arm, a charging loop is formed, and the train charging process is started. Before the train leaves the station, the train driver manual control descends the train pantograph, starts the train and leaves the station, and the on-the-spot train of station arrives the station detecting device and sends the train signal of leaving the station to station electric power monitored control system, and station electric power monitored control system separation station charging device switch, the station power supply arm is uncharged this moment, and the charging process finishes in the train station. When the train arrives at the station and the detection device is in fault, the train driver contacts a dispatcher of the control center to remotely and manually adjust the charging device, and the charging process is completed.
In the prior art, a station is generally designed as an open platform, a power supply arm is suspended above a platform rail, and from the perspective of operation maintenance safety, electrification is allowed only in the train charging process, so that a train arrival detection device is required to provide train arrival and departure signals, and then a switch of a charging device is adjusted to supply power to the power supply arm of the station. Under the condition that a line is stopped, setting the charging device to be in a dormant state, wherein a switch of the charging device cannot be closed in the dormant state; before the line begins to operate, the charging device is set to be in an awakening state, the switch of the charging device can be adjusted according to signals of train entering and exiting the station in the awakening state, and power is cut off for the power supply arm of the station.

1. most stations of the rechargeable rail transit line are overground open platforms, the train arrival detection device is easily interfered by electromagnetic interference sources, social vehicles, pedestrians and other foreign matters, the probability of mistakenly triggering the switch of the charging device is relatively high, and unnecessary equipment loss and accident risks are caused.
2. Rechargeable track traffic lines's station need set up train detection device that arrives at a station in the construction process to bury corresponding pipeline and cable underground, station electric power monitored control system need set up corresponding collection point, and develop the joint debugging on vehicle and ground, need drop into certain equipment material cost, construction cost, debugging cooperation cost, raised this functional engineering implementation cost.
3. The train arrival detection device arranged at the station of the rechargeable rail transit line has the advantages that the installation position is more prominent for avoiding signal interference, the embedding depth of related cables is not enough in consideration of cost, the damage rate of the train arrival detection device and the cables is high, the usability of the function is reduced, and the maintenance cost of field equipment of the function is raised.
