  • Publication number: 20230264725
    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.
