摘要
近年来随着科技的飞速发展，单片机的应用正在不断地走向深入，同时带动传统控制检测,日新月益更新。在实时检测和自动控制的单片机应用系统中，单片机往往是作为一个核心部件来使用，
单片机是把主要计算机功能部件都集成在一块芯片上的微型计算机。它是一种集计数和多中接口于一体的微控制器，被广泛应用在智能产品和工业自动化上，而51单片机是个单片机中最为典型和最有代表性的一种。
水塔智能水位的控制系统首先要能正确检测水位并能正确显示,并有及时调整水位的功能。系统以AT89S51作为控制核心，显示器，驱动电路等相结合来完成水位控制,充分发挥了单片机的性能。其硬件电路简单，软件功能完善，控制系统可靠，具有一定的使用和参考价值。

Abstract
In recent years along with the technical swift development, monolithic integrated circuit's application was moving toward unceasingly thoroughly, simultaneously led the traditional control examination, the Japan crecent moon profit renewal. In the real-time examination and in automatic control's monolithic integrated circuit application system, the monolithic integrated circuit often is takes a core part to use, The monolithic integrated circuit is integrates the main computer functional unit on a chip the microcomputer. It is one kind of collection counting and many connections in a body's micro controller, is widely applied in the intelligent product and in the industrial automation, but 51 monolithic integrated circuits are in a monolithic integrated circuit are most typical and the most representative one kind. The water tank intelligence water level's control system must first be able to examine the water level correctly and can demonstrate correctly that and has the prompt adjustment water level function. The system takes the control core by AT89S51, the monitor, the driving circuit and so on unifies completes the water monitor, has displayed monolithic integrated circuit's performance fully. Its hardware circuit is simple, the software function is perfect, the control system is reliable, has certain use and the reference value.
