The Research On SCADA System Of Water Company

The paper discusses the SCADA(Supervisory Control and Data Acquisition) technique on the basis of water mill.The system comprises five parts which include electric control system, data collection system, rear pressure supervisory system ,constant pressure system and sofeware system. The electric control system remote-control the start-up and stop of pump; The data collection system acquire the data with data collector and transmit data to computer by series port. Rear pressure supervisory system supervise the pressure of case occurrence of accident. Constant pressure system supply water to people in economic way. Sofeware system deal with the integration of total system and supply the interface for other system.With the design of hardwire of acquisition equipment and the output of analog signals module,the system implete the SCADA system of wnter mill successfully.
