A control system includes an interface device having a body extending between a first end and a second end and that provides power to a vehicle system from an external power source. Sensors may be coupled with the interface device and detect sensor data associated with the coupling of the external power source with the interface device. A controller receives the sensor data from the sensors and determines a coupling location at which the external power source is coupled with the interface device. The coupling location may be at a first position between the first end and the second end of the interface device. The controller controls movement of the vehicle system to change the coupling location between the external power source and the interface device from the first position to a second position between the first and second ends of the body.

The present disclosure relates to a trolley wire detection device and a trolley wire detection system. The trolley wire is disposed on a guide rail and is disposed along an extending direction of the guide rail; the trolley wire detection device includes a current collector assembly connected to the trolley wire; a power mechanism, slidably disposed on the guide rail; and an engagement assembly disposed between the current collector assembly and the power mechanism, the engagement assembly being configured to provide a preset engagement force to connect the current collector assembly and the power mechanism; wherein the power mechanism is configured to drive the current collector assembly to move along the trolley wire through the engagement assembly, and the current collector assembly is configured to be disengaged from the power mechanism when a resistance generated by the trolley wire is greater than the preset engagement force.
