The invention discloses a rail transit vehicle and train heating control circuit and control method. The control circuit comprises control units which are the same in structure and are arranged in two cab bodies respectively. The control unit comprises a plurality of heating relay coils connected with a power supply, and positive electrodes of the plurality of heating relay coils are connected with a first train line; the cathodes of the plurality of heating relay coils are grounded; and normally open contacts of the plurality of heating relays are correspondingly connected with one electric heating device respectively. The problems that the train cannot normally rise the pantograph and brake cannot be relieved and applied are solved, and normal operation and driving safety of the train are ensured.
本发明公开了一种轨道交通车辆及列车加热控制电路、控制方法,控制电路包括结构相同、且分别设置于两个司机室内的控制单元;所述控制单元包括与电源连接的多个加热继电器线圈,所述多个加热继电器线圈的正极均与第一列车线连接;所述多个加热继电器线圈的负极均接地;所述多个加热继电器的常开触点各对应与一电加热装置连接。本发明解决了列车无法正常升弓、制动无法缓解和施加的问题,确保列车正常运营及行车安全。
