The invention discloses a locomotive fireless return control circuit and a vehicle, and is applied to the field of rail transit. According to the principle of the locomotive fireless loopback control circuit, when the first end of a fireless selection switch and the second end of the fireless selection switch are connected, a brake release circuit and an emergency control circuit are connected into the locomotive fireless loopback control circuit through a second contact of a parking brake release key and a storage battery output contactor; when the third end of the fireless selection switch and the fourth end of the fireless selection switch are conducted, the brake release circuit is connected to the locomotive fireless return control circuit through a first contact of the parking brake release key; and the connection between the emergency control circuit and the locomotive fireless loopback control circuit is cut off through the emergency bypass relay and the storage battery output contactor. Therefore, the fireless return process of the driver and the conductor is simplified, the driver and the conductor do not need to get off a vehicle body to handle a hand-pulled relief ring, operation is easy and safe, working efficiency is improved, and safety of the vehicle during running is improved.
本申请公开了一种机车无火回送控制电路和交通工具,应用于轨道交通领域。其本申请提供机车无火回送控制电路的原理为:当无火选择开关的第一端和无火选择开关的第二端导通时,通过停放制动缓解按键的第二触点和蓄电池输出接触器分别将制动缓解电路和紧急控制电路接入机车无火回送控制电路;当无火选择开关的第三端和无火选择开关的第四端导通时,通过停放制动缓解按键的第一触点将制动缓解电路接入机车无火回送控制电路,并且通过紧急旁路继电器和蓄电池输出接触器断开紧急控制电路与机车无火回送控制电路的连接。可见,本申请简化了司乘人员无火回送流程,无需下车体处理手拉缓解环,操作简单安全,提高了工作效率,并提高车辆运行时的安全性。
