Design Of Water Pipe Network Remote Monitoring System Based On S7-200

With the development of technologies and improvement of productivity, remote monitoring system has been increasingly applied in many fields. City water supply monitor system plays important role in city water supply enterprises.It belongs to the family of SCADA (Supervisory Control and Data Acquisition) systems which is supported by automatic control technology, communication technology and computer technology.Along with the rapid development of the computer technology,most water supply enterprises have established water supervisory control system so as to utilize water resources properly and improve the level of production management.But under current circumstances, except a few big enterprises , most enterprises still encounter many problems such as lagging communication method, fall-behind information sharing among departments,low utilizing of resources and limited automation control level.This paper presents a system of wireless remote data acquisition , transmission , supervision and analysis based on Web and GPRS.This paper combined the actual situation with the design request of the water station, based on the GFS HMI and S7-200 series PLC, designed and developed the Remote Monitoring system for water pipe network; finally, realized the system in water station of Shanxi province.This paper firstly introduced the significance and the development of remote monitoring system, discussed the actuality of the remote monitoring system for water pipe network, researched on the basic technology of remote monitoring, and the requirement of remote monitoring system. After that, the paper united the Water Pipe Network 's feature, put forward a design plan and a detailed scheme; at last, realized the water pipe network remote monitoring system.The system united remote monitoring and local monitoring .In water station, we used monitoring circuit designed with S7-200 series PLC to monitoring, and sent the status and alarm data to special server with fixed IP through GPRS device. The operators access the data through Internet and save in their local database. They monitor the water pipe network through configuration software.
