摘　　要：针对水资源污染日益严重的问题,融合WSN技术、嵌入式技术和4G技术重点设计了一款水质自动监测系统。系统通过数量众多的传感器节点采集水质的温度、pH值、电导率和浊度等参数,并将其传输给以树莓派3为控制核心的无线网关。无线网关将数据通过4G网络传输至OneNET云,监测中心从云服务器获取数据进行相关处理。通过搭建的实验系统进行功能测试。测试结果表明,所设计的硬件系统能够对水质参数进行远程实时监测,实现数据的实时、精确、低功耗采集与传输,有效降低了人力支出,且系统部署方便,组网灵活,应用前景广阔。Aiming at the increasingly serious water pollution problem,an automatic water quality monitoring system is designed by integrating WSN technology,embedded technology and 4G technology.Through a large number of sensor nodes,the system collects water temperature,pH,conductivity,turbidity and other parameters,and transmits them to the wireless gateway with raspberry Pai 3 as the control core.The wireless gateway transmits the data to OneNET cloud through 4G network,and the monitoring center obtains the data from the cloud server for relevant processing.Through the function test of the experimental system,the test results show that the designed hardware system can carry out remote real-time monitoring of water quality parameters,achieve real-time,accurate,low-power data acquisition and transmission,effectively reduce the human expenditure,and the system is easy to deploy,flexible in networking,and has broad application prospects.
