The invention provides a full-automatic driving train length detection system, and relates to the technical field of full-automatic driving rail transit signal systems.The method comprises the steps that each train is provided with a train length detection circuit, and each train length detection circuit comprises a first loop and a second loop which are independent of each other; the first loops and the second loops of the two mutually connected trains are electrically connected respectively; when the first loop and the second loop are connected with the power supply voltage, the first loop and the second loop generate different voltage drops. Each train is further provided with a train-mounted ATC system, different voltage drops are detected through the train-mounted ATC systems and compared with power supply voltage for calculation, and the length of the whole marshalling train and the position of the train where the current train-mounted ATC system is located in the whole marshalling train are obtained. The train marshalling number and length can be accurately detected, so that the train parameters of the marshaled trains are called to protect the trains, and it is guaranteed that the trains do not run in a degraded mode.

    本发明提供了一种全自动驾驶列车长度检测系统,涉及全自动驾驶轨道交通信号系统技术领域,该方法包括:每节列车上均设置有列车长度检测电路,列车长度检测电路包括相互独立的第一回路和第二回路,相互连接的两节列车的第一回路和第二回路均分别电连接;当第一回路及第二回路均接通电源电压时,第一回路和第二回路会产生不同的电压降;每节列车上还均设置有车载ATC系统,通过车载ATC系统检测出不同的电压降,并与电源电压进行比对计算,得出整列编组列车的长度,及当前车载ATC系统所在列车在整列编组列车中的位置。本发明能够准确检测列车的编组数量及长度,从而调用编组后列车的车辆参数对列车进行防护,保证列车不降级运行。
