Design of Water Supply Control System for Living Quarters Based on WinCC

Abstract：The higher requirement for the water quality and water supply systems is rising with the rapid development of the society and economy. The design of water supply systems with the characteristic of high performance and high energy-saving become possible with the employment of advanced automation technology, control technology and communication technology.

This design by WinCC monitoring as the core, the monitoring system and site operation box can achieve dual control, can carry out the automatic switchover of the hand, local and remote, frequency conversion and power switch. The configuration picture directly, can display the running state and the hydraulic pump. Sampling and control signals between the measurement signals output by the PLC module, computer and PLC communication modules implement the transmission of information to WinCC software platform control software and PC management software, to achieve the living quarters of the automatic control of water flow . The design of the application of the WinCC monitoring software, programmed using configuration technology to realize the constant pressure the monitor of water supply system, with high efficiency and energy saving, automatic, reliable, easy maintenance, convenient management advantages.

Key words: WinCC； Water supply system ；Monitor
