摘　　要：本文基于MQTT通信协议,采用前后端分离的MVVM(Model View-View Model)软件架构,设计了一套水质远程监测系统,实现多节点水质数据的远程监控。该系统终端节点采用RS-485型TDS(Total Dissolved Solids)和pH变送器采集水质温度、TDS值和pH值,通过4G透传DTU(Data Transfer unit)将封装在MQTT报文中的信息上报到云服务器,用户可对设备状态与水质信息进行实时监控。测试结果显示,该系统运行稳定,可以满足远程水质监测需求。Based on MQTT communication protocol and MVVM software architecture,it designed a set of water quality remote monitoring system,which realized the remote monitoring of multi-node water quality data.The system used RS-485 type TDS and pH transmitter to collect water quality temperature,TDS value and pH value,reported the information encapsulateed in MQTT messages to the cloud server through the 4G-transmission DTU.Users can use the system to monitor the equipment status and water quality information in real time.Test results showed that the system was stable and could meet the need of remote water quality monitoring.
