摘要

矿山井下环境特殊,且开采过程常伴随有毒有害气体,在对此类环境参数进行采集与传输时,常用无线通信技术存在通信距离短和抗干扰差的弊端。为解决此问题,设计了一套基于LoRa和物联网技术的矿井环境监测系统,对井下环境进行实时监测,并通过LoRa模块进行传输。监测系统包括数据采集端、汇总终端和数据监测平台3个部分,数据监测平台包括云平台和微信小程序。数据采集端搭配环境多传感器,通过布置多个LoRa中继节点传输监测点数据,实现较长距离无线传输,汇总终端将数据处理后通过WIFI发送至云平台,微信小程序数据通过调用云平台数据得到,最终完成监测数据的存储及可视化。测试结果表明:该系统功能稳定,能够实现井下的环境监测功能,易于安装、便于二次开发且井下无需排线。本研究进一步完善了矿山安全监测系统,增强了矿山灾害防治能力与应急救援能力。

Abstract

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.
