摘要： A method, system and device for controlling a door of a railway vehicle are provided. The method comprises: a door control instruction sent by a transponder is received when a railway vehicle draws into the station, wherein the door control instruction is used for determining a door of the railway vehicle at a platform side; and the railway vehicle is controlled to open the door of the railway vehicle at the platform side according to the door control instruction, thereby solving the technical problem that the door of a railway vehicle at the non-platform side may be opened by mistake by a driver due to human factors because the door of the railway vehicle at the platform side is manually opened when the railway vehicle stops.

摘要： A switching circuit for implementing coupling at a random end of a train includes a coupling change-over switch which includes a switching position, a normal position, and a disconnected position. The coupling change-over switch includes a group of terminals A, B, C, D, E, F, G, and H that are related to a train running direction signal. The terminals A and C are connected to each other, as well as the terminals E and G, the terminals B and H and the terminals D and F. The pair terminals A and C and the pair of terminals E and G act as terminals of forward and backward running signal train control lines respectively. The pair of terminals B and H and the pair of terminals D and F are connected to terminals of forward and backward running signal wires of a train electric coupler connector respectively.
