The underground environment of mine is special,and the mining process is often accompanied by toxic and harmful gases.For the collection and transmission of such environmental parameters,the common wireless communication technology has the disadvantages of short communication distance and poor anti-interference.To solve this problem,a mine environment monitoring system based on LoRa and IOT technology was designed to monitor the underground environment in real time and transmit through LoRa modules.The monitoring system includes three parts,namely data collection end,aggregation terminal,and data monitoring platform,and the data monitoring platform includes cloud platform and WeChat applet.The data collection end is paired with environmental multi-sensors and transmits monitoring point data by arranging multiple LoRa relay nodes to achieve longer distance wireless transmission.The aggregation terminal sends the data to the cloud platform through WIFI after processing.The WeChat applet data is obtained by calling the cloud platform data and finally completes the storage and visualization of monitoring data.The test results show that the system is functionally stable,can realize the environmental monitoring function of underground,and it is easy to install,easy to secondary development and no need to line up underground.This study provides a reference for the design of underground environmental monitoring systems in similar mines.This study can improve the mine safety monitoring system and enhance the capacity of mine disaster prevention and emergency rescue.
