In the whole train state of the motor train unit, the electric function of the automatic coupler is given by a CCU (train control unit) of a cab. When the components are not loaded (such as in an assembly stage or ground overhaul), a special test bed needs to be designed to simulate the control process and the monitoring process of the cab so as to verify that the components meet the use requirements of the vehicle.
Referring to fig. 1, an embodiment of the present invention provides an automatic coupler detection circuit for a rail train, including:

The locking cylinder inductive switch S1, the coupler extension inductive switch S2 and the coupler retraction inductive switch S3 can sense the states of the locking cylinder and the automatic coupler and perform corresponding switching actions. For example: the locking cylinder induction switch S1 is closed when sensing locking of the locking cylinder, otherwise, the locking cylinder induction switch S1 is in an open state; the coupler extension inductive switch S2 is closed when sensing that the coupler extends to the proper position, otherwise, the coupler extension inductive switch S is in an open state; the coupler retraction sensing switch S3 is closed when it senses that the coupler is retracted into position, and is otherwise in an open state.
Each detection unit can form a detection loop with the induction switches when the induction switches are closed, so that whether the locking cylinder is locked, the automatic coupler stretches out to be in place or not and the automatic coupler retracts to be in place or not is detected, and a worker can accurately judge the electrical function of the automatic coupler.
