摘要

 供水是一个关系国计民生的重要产业。随着社会的发展和人民生活水平的提高，对城市供水提出了更高的要求，要满足及时、准确、安全保证充足供水，如果仍然沿用人工方式，劳动强度大，工作效率低，安全性难以保障，为此必须进行水塔水位控制自动化系统的改造。可编程控制器( PLC) 因其高可靠性和较高的性价比在工业控制中得到广泛的应用。本文针对目前比较流行的控制技术，利用PLC和传感器构成了水塔恒水位的控制系统。改造后的水塔水位自控系统，实现水塔水位自动控制系统，远程监控，实现无人值守。

Abstract
 The water supply is a relations national economy and the people's livelihood important industry. Along with society's development and living standards' enhancement, proposed to the urban water supply a higher request, needs to satisfy promptly, accurate, the security guarantees sufficient water supply, if still continued to use the artificial way, the labor intensity is big, the working efficiency is low, the security safeguards with difficulty, for this reason must make the water tank water monitor automated system's transformation. Because the programmable controller (PLC) its redundant reliability and the high performance-to-price ratio obtains the widespread application in the industrial control. This article in view at present the quite popular control technology, constituted the water tank permanent water level control system using PLC and the sensor. After the transformation water tank water level autonomous system, realizes the water tank water level automatic control system, the long-distance monitoring, realizes unattended.
