摘要
为实现地铁列车的精确定位停车,北京地铁5号线,根据其自身特点,通过地面铺设ATO环路,并将地面信息以调制2FSK信号的模式发送至交叉环路,环路信息解调设备对地面环路发送的调制信息进行识别判断,解调出地面发送的信息,实现车-地通信;通过采集地面环路的交叉点,得到列车位置,为列车精确停车提供准确可靠的数据。
stopping in loop in the According to the characteristics of Beijing Line 5, it was its ATO system. By laying the ATO loop on the ground, mode of 2FSK signal modulation. The data demodulation intended to achieve precise location the ground data is sent to the ATO equipment of the loop identifies the modulation data transmitted by the ground loop and demodulates the data transmitted by the ground equipment, thus realizing train - ground communication. By collecting the crossing point of the ground loop,the accurate location of the train can be obtained, providing accurate and reliable data for train precise stopping.
