摘　　要：针对暗渠中易燃易爆危险气体的监测问题,设计了一套基于LoRa无线通信的自组织、自动监测预警系统。系统自底向上由数据采集节点、网关节点和云端服务器构成,节点之间的数据通信采用LoRa无线通信的方式,网关对收集的数据进行封装、打包上传,云端运行的Web服务器将网关上传的数据进行解析、筛选及实时动态显示,当易燃易爆气体浓度达到一定阈值时会触发报警,通过短信方式通知相应的管理人员进行处理,实现暗渠危险气体的自动监测以及危险预警功能。A self-organizing automatic monitoring and early warning system based on LoRa wireless communication is designed for the detection problem of flammable and explosive dangerous gases in underground channel.The system is composed of data acquisition node,gateway node and cloud server from bottom to top.The data communication between nodes adopts LoRa mode.The cloud runs web server to analyze,screen and display the data uploaded from the gateway.When the concentration of flammable and explosive gas reaches a certain threshold,the alarm will be triggered and the corresponding management personnel will be informed to deal with it by SMS to realize the automatic monitoring and danger warning function of harmful gas in underground channel.
