摘 要
设计基于单片机技术的水箱液位控制系统的目的是应用单片机的控制技术，以STC89C51单片机为核心来控制水箱的液位，并实现了报警和手动、自动切换功能。本设计包含四路液位输入，通过两个工作泵，一个备用泵来实现液位的自动调节。其中，水箱液位的测量是通过自制的开关式传感器将液位信号传送给STC89C51的P1口，并对其进行分析处理，然后根据控制要求输出控制信号，控制给水泵工作，进而保持水箱有正常的液位。同时也详尽的介绍了此次设计中最重要的组成部件。该设计介绍了STC89系列单片机基本结构与相关的硬件资源，液位传感器的设计与工作原理。该系统操作方便、性能良好，比较符合日常生产生活用水系统控制的要求。本文还详细的给出了相关的硬件框图和软件流程图，并且根据外围硬件电路的设计思想，编制了该汇编语言程序。

Abstract
The purpose of designing a water level controlling machine based on SCM is apply the SCM controlling technology. This system uses STC89C51 and has a function with alerting, manual and automatic controlling. This system includes 4-way water-level inputs, two working motors, and a standby motor, which can adjust the water-level automatically. Another, it is easy-used , Among them, the water tank water level survey is transmits through the self-made switch type sensor the water level signal for the STC89C51P1 mouth, and carries on analysis processing to it, then the basis controls the request output control signal, controls the feed pump work, then maintains the water tank to have the normal water level .Simultaneously also in exhaustive introduction this design most important composition part . This design introduced the STC89 series monolithic integrated circuit basic structure and the correlation hardware resources, the water level sensor design and the principle of work good performance, which is suit for the water need of routine controlling. This paper also tells the design outline of hardware and software ,and compile a program with compilation language.
