水塔水位控制系统

摘 要

水塔的作用：一是蓄水，在供水量不足之时，起着调节补充的作用。二是利用水塔的高势，自动送水，使自来水有一定的水压扬程。本次单片机系统设计的目的是利用单片机应用技术，以8051单片机为核心控制水塔的水位，并可实现了报警和手动、自动切换功能，为了达到节能的目的，提高供水系统的质量，考虑采用可编程序控制器、继电器和传感器技术，设计出一套适用的水塔水位控制方案。该方案在硬件基础上配合软件实现了警戒水位报警，并可切换手动自动两种工作方案。

该系统操作方便，性能良好，简单便宜，比较符合电厂水系统控制的需要。本文还详细的给出了相关的硬件框图和软件流程图，并编制了该汇编语言程序。

The Water Tower water level control system

ABSTRACT

Tower: one is the effect of water supply, and the supplementary role plays a regulation. Two is to use the high towers, automatic water tap water, have certain hydraulic head. The single-chip microcomputer system is designed by using the microcomputer application technology, 8051 single-chip processor core control towers, and can achieve a level alarm and manual, automatic switching function, in order to achieve the purpose of saving energy, improving the quality of water supply system, consider using a programmable controller, relays and sensor technology, design a set of suitable water control scheme of the towers. Based on this method, the hardware with software realize the warning level alarm, and can be switched manually two work plan.

This system, convenient operation, good performance, simple and cheap, compared with the power to control water system. The paper also gives a detailed related hardware diagram and software flow chart, and the assembly language program
