  • Patent number: 12344296
    Abstract: The invention relates to a multi-station integrated code sending control method, an electronic device and a medium. The method comprises the following steps: 1. supervising, by a train control and interlock integration device, a plurality of adjacent stations; 2. connecting the train control and interlock integration device to a train control center device or a train control and interlock integration device of other adjacent non-integrated stations through a communication interface; 3. dividing all integrated stations into stops, relay stations, lines and non-wiring stations according to station types; and 4. determining low-frequency codes of all stations through cyclic traversal to realize the code sending function. Compared with the prior art, the invention has the advantage of being high in efficiency.

  • Publication number: 20250178654
    Abstract: An interconnection and intercommunication method and system for a virtual marshalling train control system in a heavy haul railway. The method includes: determining a switching area for switching ground equipment between an existing line and a virtual marshalling line; switching a ground equipment control right when a train runs to within a range of the switching area; and after switching of the ground equipment control right is completed, sending, by the ground equipment in the virtual marshalling line, a marshalling command to on-board equipment of the train, and virtually marshalling, by the on-board equipment, the train corresponding to the on-board equipment and a front train in a formation based on the marshalling command. According to the present invention, the switching between different signal systems can be implemented, and the efficiency of train operation can be improved.
