基于网络的河流水质远程监测系统设计及应用

Design and Application of Remote Monitoring System of River Water Quality Based on Network

针对河流水质传统检测方式的不足之处,本文把计算机技术、PLC网络技术与就地的水质检测仪器结合起来,组建了一个基于网络的河流水质远程监测系统。此系统的网络有两层,第一层网络是由S7-200与SC1000组成的Modbus网络,第二层网络是由检测站的控制器与监控室的PC机组成。通过网络,系统实现了远程水质检测和数据采集,通过组态王V6.52,实现了数据的集中分析处理。

In view of the defects of traditional monitoring method for river water quality,a remote monitoring system based on network was established by integrating computer technology,PLC network technology and local water testing instruments.The system has two layers,first is Modbus network which is made up of S7-200 and SC1000 and the second is composed of controller in testing station and PC in monitoring room.Through network,remote water quality testing and data collecting were realized and concentrating analysis and processing of data came true by configuration king V6.25.
