Research and Application of Wireless Roof Pressure Sensor for Coal Mines Based on WAVEMESH Self-organizing Network
TIAN Shuaishuai
Abstract：Through research on the on-site use of wireless roof pressure sensors currently in use in coal mines,it was found that the sensors generally have problems such as high circuit power consumption,short battery life,complex working conditions of underground coal mining faces,unstable wireless networks,data loss,and the inability to capture data when there is a sudden change in support pressure due to timed data transmission.A wireless mine pressure sensor based on WAVEMESH self-organizing network was designed.The sensor adopts STM32 microcontroller as the main control unit and relay type self-organizing network transmission method.It can real-time collect,display and transmit the pressure of the front column,rear column,and front probe beam of the coal mining face support.The underground pressure data was displayed in real-time on the upper computer of the ground monitoring room.When the working environment of the underground working face is not good,the sensor data can be stored regularly and uploaded after the network was restored.This sensor has the characteristics of low power consumption,long battery standby time,strong network robustness,ability to capture sudden pressure changes data,and high data acquisition accuracy.After being applied in multiple coal mine sites,it has achieved good results.
