Abstract: In order to improve the efficiency and intelligence level of railway communication signal detection, this paper designed a control and editing system for detection of communication and signal, which used FreeSql and database triggering mechanism, asynchronous TCP communication and multi-point connection technology, and disconnection and reconnection mechanism to implement the operation status monitoring, task automatic control, testing data review, and one click generation function of the detection daily report of the communication and signal detection system. The experimental results show that the designed system has improved the efficiency and quality of communication and signal detection, and implemented intelligent detection of communication and signal.
