基于ZigBee和4G的空气质量远程监测系统设计

Design of Air Quality Remote Monitoring System Based on ZigBee and 4G

针对现阶段科研及市场实际需求,总结高校相关专业实验存在问题,设计开发了一种远程监测系统。系统由空气质量探测器、网络协调器和空气质量远程监测软件组成。使用STM32芯片作为MCU,采集PM2.5和PM10的参数并实时显示,将多个监测点采集到的数据通过ZigBee Mesh网集中到网络协调器,再由4G通讯的方式将数据传输到云平台。远程监测软件通过Internet读取并显示各监测点采集的数据,实现了各监测点数据的显示、报警值设定、实时曲线和历史曲线显示等功能。该系统综合了嵌入式、无线传感网络及上位机界面设计,可有效提升学生的综合试验能力和创新能力。

In view of the current research and market actual needs,the problems of relevant professional experiments in colleges were summed up,the experimental system was designed. The system consists of air quality detectors,network coordinator and air quality remote monitoring software. It uses STM32 chip as MCU,collects the parameters of PM2.5 and PM10,displays them in real time. The data collected by multiple monitoring points are collected into the network coordinator through ZigBee Mesh network,then transmitted to the cloud platform by the means of 4 G communication. The air quality remote monitoring software gets and displays the data collected by each monitoring point through the Internet,and realizes the function of data display,alarm value setting,real-time curve and historical curve display,etc. The system integrates embedded system,wireless sensor network and the design of host computer interface,which can effectively improve students’ comprehensive experimental ability and innovation ability.
