基于物联网的汉江水环境参数监测系统设计

为实现南水北调中线水源地汉江的水体环境参数智能化监测,研究设计一种基于物联网的汉江水环境参数监测系统。该系统由监测主机和检测终端组成,监测主机通过LoRa无线方式发送采集控制指令到检测终端,检测终端接收指令并实施水温、pH值、浑浊度等水体环境数据采集,并将采集数据通过LoRa无线方式发送给监测主机,由监测主机完成数据分析、显示和异常语音告警,监测主机具有基于NB-IoT的OneNET云平台自动接入与数据上传功能,能将检测数据自动上传到OneNET云平台,管理人员通过手机app登录云平台,即可实现水体环境的远程监测管理功能。实验测试结果表明：本系统各项功能运行较为稳定,监测主机和检测终端的LoRa无线有效通信距离约为1640米,系统设计方案合理可行,能够为南水北调水源地水体环境智能化监测管理提供技术基础和方案参考。

Han River Water environmental parameter monitoring system based on Internet of things

In order to realize the intelligent monitoring of the water environment parameters of the Han River, the water source of the middle route of the South-to-North Water Diversion Project, a monitoring system of water environmental parameters of Han River based on Internet of things is designed, The system consists of a monitoring host and a detection terminal, the monitoring host sends acquisition control instructions to the detection terminal through LoRa, the detection terminal receives instructions and collect the water environment data such as temperature, pH value, turbidity and so on, and then sends the collected data to the monitoring host through LoRa, the monitoring host performs data analysis, display and abnormal voice alarm,and the monitoring host also have the automatic access and data upload functions of OneNET cloud platform based on NB-iot, which can automatically upload the detection data to OneNET cloud platform, managers can log in to the cloud platform through the mobile app to achieve remote monitoring and management of the water environment. The experimental results show that each functionSof this systemSrunsSstably,the effective LoRa wireless communication distance between the monitoring host and the detection terminal is about 1640 meters. the system design scheme is reasonable and feasible, which can provide technical basis and scheme reference for the intelligent monitoring of water environment in the water source of the South-to-North Water Diversion Project.
