The invention belongs to the field of train positioning and communication of a rail transit signal system, relates to a rail transit positioning and communication integrated method, system, equipment and medium, and aims to improve and redesign a frame format of a secondary radar, utilize time division multiplexing of a communication frame and a positioning frame, and measure the distance through a plurality of vehicle-mounted labels and a ground base station. According to the invention, a train is positioned in a mode of inquiring a built-in electronic map, so that a signal system can control and use the train, and meanwhile, three train-ground modes of point-to-point communication based on a positioning frame, broadcasting based on a communication frame and point-to-point communication based on the communication frame are provided, and train control information interaction between the train and a control center is realized, so that communication and positioning integration is realized. Compared with the prior art, a standby communication positioning system is provided for a rail transit signal system, the reliability of communication and positioning of the signal system is improved, the system is switched to a main system when the system breaks down, and therefore normal work of a train operation control system is guaranteed.

    本发明属于轨道交通信号系统的列车定位和通信领域,涉及一种轨道交通定位通信一体化方法、系统、设备及介质,立足于改造和重新设计二次雷达的帧格式,利用通信帧和定位帧的分时复用,通过多个车载标签和地面基站的测距,及其查询内置电子地图的方式,实现列车定位,以供信号系统控制使用,同时提供基于定位帧的点到点通信、基于通信帧的广播、基于通信帧的点到点通信三种车地方式,实现列车和控制中心之间的控车信息交互,从而实现通信定位一体化。与现有技术相比,本发明为轨道交通信号系统提供了备用通信定位系统,提高信号系统通信和定位的可靠性,并在其发生故障时切换为主用系统,从而保证列车运行控制系统的正常工作。
