Abstract: In view of the complex wiring, high cost, and poor flexibility of the wired monitoring system for coal mine equipment status, in order to improve the limited communication distance, poor anti-interference ability, and high energy consumption of the existing wireless monitoring system, and solve the problem of the existing monitoring system data. To access the shared information island problem, a wireless sensor acquisition system for mines based on MEMS technology is studied. The overall design plan of the system, the hardware circuit design and software implementation of the collector and concentrator (including the compilation of communication messages) are introduced in detail, and the reliability of the system is verified by tests. The results show that the wireless sensor acquisition system can flexibly adapt to the complex working environment of coal mines and underground, realize real-time, long-distance, and wireless transmission of vibration and temperature signals of coal mine equipment, and can provide rich resources for health monitoring and fault diagnosis of mining equipment Data support.
