The invention discloses an electrical vehicle ground power supply system and a vehicle approaching confirmation control method thereof. A magnetic signal covering strip is arranged at the bottom of avehicle, and N magnetic field sensors are uniformly arranged on each power supply module on a line along a vehicle advancing direction in sequence. When the n magnetic field sensors measure vehicle magnetic signals at the same time, the power supply modules are disconnected from a safety negative electrode, and a power supply is connected with the power supply modules; otherwise, the power supplyis disconnected with the power supply modules, and the power supply module is connected with the safety negative electrode. The approaching state of the vehicle can be accurately confirmed, the powersupply or the safety negative electrode is timely and safely connected or disconnected with the power supply modules, and adverse effects of various mobile communication devices on safe operation of the vehicle and safe power supply on the ground are thoroughly eradicated. When n is equal to or greater than 2, misoperation caused by external factors such as playing of magnet blocks by children canbe further avoided.

    本发明公开了一种电气车辆地面供电系统及其车辆接近确认控制方法,车辆底部设置磁信号覆盖条,线路上的每个供电模块沿车辆行进方向顺序均匀设置N个磁场传感器。当n个磁场传感器同时测到车辆磁信号时,断开供电模块与安全负极的连接,接通电源与供电模块的连接;否则断开电源与供电模块的连接,接通供电模块与安全负极的连接。可以准确无误地确认车辆接近状态,及时安全地接通或切断电源或安全负极与供电模块的连接,彻底杜绝各种移动通讯设备对车辆安全运行及地面安全供电的不良影响。n取值2及以上时,可以进一步杜绝外界因素影响例如儿童玩弄磁铁块而造成的误动作。
