The invention discloses a control circuit and rail vehicles. The control circuit comprises a self-resetting coupling button switch. After coupling instructions of the target rail vehicle and the to-be-coupled rail vehicle are received, the self-resetting coupling button switch is closed, under the closed state of the self-resetting coupling button switch, a coupling relay connected with the self-resetting coupling button switch obtains power and is switched off through an emergency braking loop built in the target rail vehicle, and an emergency braking loop between the target rail vehicle andthe to-be-coupled rail vehicle is built; after the self-resetting coupling button switch receives uncoupling instructions of the target rail vehicle and the to-be-coupled rail vehicle, the self-resetting coupling button switch is closed. Through the control circuit and the rail vehicles, the problem that in the relevant technology, after flexible marshalling between train vehicles is achieved, emergency braking loops are difficult to flexibly build is solved.
Description
technical field [0001] The invention relates to the technical field of train control, in particular to a control circuit and a rail vehicle. Background technique [0002] With the popularization and application of trains, in the process of calling trains, it is often necessary to flexibly organize the vehicles in the train, that is, to couple and uncouple the vehicles in the train. In the prior art, the formation of vehicles in a train usually needs the assistance of a trailer, and the vehicle to be articulated is dragged to the vehicle to be articulated by the trailer, so as to realize the articulated between vehicles and the like. Therefore, this kind of processing method is not automatic enough, and it is difficult to realize flexible grouping between vehicles in the train. [0003] Aiming at the problem in related technologies that it is difficult to flexibly establish an emergency braking loop after flexible marshalling between train vehicles, no effective solution has...
