摘要
针对日益严重的城市内涝状况,设计了一种基于LoRa的城市内涝监测预警系统,以传感器和LoRa无线通信网络为核心,将采集到的水雨情数据通过LoRa通信模块上传至网关,网关汇集数据后通过GPRS传输到中心站,构建了一套低功耗、低成本,灵活组网而且远距离通信的城市内涝监测预警系统。该系统解决传统城市水雨情监测数据通信能力差与无法泛组网的问题,提高城市排水和应急处置效率,减少人民群众伤亡和财产损失。
Aiming at the increasingly serious urban waterlogging situation,an urban waterlogging monitoring and early warning system based on LoRa is designed.Taking the sensor and Lora wireless communication network as the core,the collected water and rain data are uploaded to the gateway through Lora communication module,and the gateway collects the data and transmits it to the central station through GPRS,so as to build a set of low-power and low-cost,urban flood monitoring and early warning system with flexible networking and long-distance communication.The system solves the problems of poor communication ability of traditional urban water and rain monitoring data and inability to pan network,improves the efficiency of urban drainage and emergency disposal,and reduces people’s casualties and property losses.
