摘要：在居民的日常用生活中，有时候可能会因为区域性的停水对生活造成不便，而这时候储水罐就能发挥它的作用：在缺水时间为居民缓解用水压力，传统的人力注水费时费力，会造成不必要的人员浪费。相比传统的人力注水，自动给水控制系统能根据情况自动储水，减少了人力注水所造成的不必要的麻烦和资源浪费，又因为自动给水控制系统自动化程度高，结构简单、成本低，易于实现，所以更能给居民的日常供水提供便利。其中需要注意的是，本次设计是利用微机控制系统对给水设备中的压力罐的压力进行检测，当压力超过上限时，系统停止工作；压力低于下限时系统开始工作，可以判断出用水情况，自动选择工作方式。以及系统缺项运行的报警系统。

Designing of Automatic Feed Water Control System
Abstract： In the residents’ daily life, sometimes it may be because of a regional water supply cause inconvenience to life, but this time storage tank can play its role: in the short of water for residents to relieve the water pressure, traditional human injection is time-consuming and laborious, will cause unnecessary waste. Compared to the traditional human water, automatic water supply control system can according to the situation of the automatic water storage, reducing the human water flooding caused by unnecessary trouble and waste of resources, and because of the automatic feed water control system has a high degree of automation, simple structure, low cost, easy to implement, so the more can provide convenience to people’s daily water supply. Operation of the system which need to pay attention to is that this design is to use microcomputer control system to detect the pressure tank, the pressure in the water supply equipment, when the pressure exceeds the upper limit, the system stops working; pressure lower than the lower limit, can judge the situation of water, automatic selection of industry and trade way. Alarm system for missing operation of system.
Keywords：pressure, water tank, automatic control
