| Summary: | In view of problem of complex structure, large power consumption of sensor and data instability existed in wired communication mode of pressure monitoring system of underground coal mine, coal mine pressure monitoring system with low power consumption based on ZigBee was designed. The system uses pressure sensor with low power consumption to collect data, and the data was summarized to sub-station through ZigBee wireless transmission, then sub-station uploaded the data to PC software after data packaging and processing, so as to achieve real-time monitoring of underground tunnel pressure data. It reduces power consumption of sensor, and thereby increases system life.
