The coal mine safety monitoring system is the key system to ensure the safe production of mine. It is necessary to upgrade the mine safety monitoring system and strengthen the anti-interference ability of the related equipment. The monitoring system and the equipment are designed for the mechanical structure design, software design and hardware circuit design of the monitoring equipment. Anti-jamming capability. Combined with the actual production status of the mine to optimize the coal mine safety monitoring system, through the relevant test detection system related parameters. The practical application results show that the optimized safety monitoring system and anti - jamming equipment can pass the test items of 3 - level electrostatic discharge immunity test and two - level radio frequency electromagnetic radiation immunity test.
