(Regarding the problems of viewing blind spots and widening difficulties in the coal mine monitoring system at that time, ZigBee was used to facilitate networking, strong expandability, good fault tolerance, low power consumption and low cost. Ultra-low power consumption MSP430 microcontroller and CC2430 RF module A coal mine monitoring system based on wireless sensor network is designed for the center. The system adopts the method of combining wireless communication and CAN bus to transmit the collected data to the monitoring center.)
