摘　　要：开发了一套基于Niagara的多参数水质远程在线监测系统,可对水体的pH值、溶解氧、浊度、温度、氨氮含量、电导率和化学需氧量等重要水质参数进行实时监测。利用无线数据传输单元(DTU)对数据网络进行转换,并通过4G网络将水质数据传送到远端服务器。服务器端部基于Niagara的水质监测平台,进行相关信息的采集、统计与分析。实验结果表明,该系统具有数据采集迅速、数据传输安全以及操作简单等优点,可以应用于河流、湖泊的水质远程在线监测作业。A multi-parameter remote on-line water quality monitoring system based on Niagara is developed,which can monitor important water quality parameters such as pH value,dissolved oxygen,turbidity,temperature,ammonia nitrogen content,electrical conductivity and chemical oxygen demand in real time.The wireless data transfer unit(DTU)is used to convert the data network,and the water quality data is transmitted to the remote server through 4G network.The server end is based on Niagara's water quality monitoring platform for the collection,statistics and analysis of relevant information.The experimental results indicate that the system has the advantages of fast data acquisition,safe data transmission and simple operation,and can be applied to remote on-line monitoring of water quality in rivers and lakes.
