In order to solve the problems of low intelligence of data monitoring and single debugging method for platform safety gate equipment in rail transit, this article adopted modular design method to implement platform safety gate intelligent monitoring system based on wireless communication. The article completed the overall system architecture design and the main function design of the system, and described in detail the key technologies of the system, such as "data acquisition module design","gate control unit(DCU) design","wireless transmission module design". The principle and programming of the core chip M20 of the wireless transmission module were studied and designed. The related work was verified by full test in the laboratory. The tester could monitor the system-level data, platform-level data and single-door data of the platform safety gate system in real time and debug the single-gate quickly with a handheld wireless terminal. The test results show that the system can implement wireless monitoring of the status of platform safety gate equipment, improve the efficiency of metro operation and the flexibility of maintenance and protection of station staff, and ensure the safety and reliability of platform safety gate system.
