摘要
随着社会经济的迅速发展，人们对供水质量和供水系统可靠性的要求不断
提高;再加上目前能源紧缺，利用先进的自动化技术、控制技术以及通讯技术，
设计高性能、高节能、能适应不同领域的恒压供水系统成为必然趋势。
本课题用 PLC 实现了自动供水控制系统，介绍了恒压供水的基本原理以及
系统构成的基础，说明了可编程控制器〔PLC〕在恒压供水系统中所担任的角
色。从系统的整体设计方案和实际需求分析开始，紧密的联系实际生活的需要，
力求做到使系统运行稳定，操作简便，解决实际中问题，保证供水安全、快捷、
可靠。

ABSTRACT
With the rapid development of social economy, it is demanded the better of water
supply’s quality and reliability of water supply system.Meanwhile energy resources
are seriously lack. So it is inevitable tendency to design water supply system which
has high function and saves on energy well, with help of advanced technique of
automation,control and communication. At the same time this system can adapt
different water supply fields.
This subject realize the automatic water control system that used of PLC ,it
introduced the basic principle that constant voltage supplies water and foundation that
the system form , have stated the role served as of the programmable controller (PLC )
in the water -supply system of constant voltage. Since the whole design plan of the
system and actual demand are analysed, the need of close life of intergrating with
practice, make every effort to make sure to make the system run steadily, easy and
simple to handle, solve and hit the problem actually, guarantee to supply water of the
security, swift , reliable. Constant voltage has supplied water and guaranteed to
support the water quality amount, the control system taking PLC as host computer has
enriched the systematic control function, have improved systematic dependability.
Key word: PLC (programmable controller ), Constant voltage, supplies water,
