Abstract: In order to monitor the working state of Shearer in the fully mechanized face of coal mine, a wireless low power coal miner monitoring system is designed. The system through the micro energy module will collect the vibration energy of the shearer during operation after the conversion for use of power system, and the data acquisition module will work the shearer's acceleration and temperature information collection, eventually transferred to the CC2530 wireless transmission module for wireless transmission. After testing, the power consumption of the system is only 3.6mA under the 3.7V power supply, the temperature error is less than 0.5 degrees, and the acceleration error is less than 1%, so that the system can effectively monitor the state of the shearer.
