摘 要
随着经济的发展、科技的进步，人们的生活节奏变得越来越快，对于生活质量的的追求也越来越高。高效、方便、节能越来越受到人们的重视。特别是随着电子技术产业走向集成化、智能化转变以后，人们对居家生活的各方面都有了更高的要求。窗帘作为每个家庭生活中最必须的家居用品之一，自然也需要满足人民更舒适性的需求。但传统的窗帘采光及避光问题主要采用的是手动开闭窗帘，每天早开晚关不仅费力而且很多方面不够人性化，特别是别墅或复式房的大窗帘，不仅长，而且重，用时需要很大的力才能开关窗帘，特别不方便；于是电动窗帘应运而生。
本文介绍了设计制作一个完整的自动窗帘控制器需要做的理论分析以及其制作过程。自动窗帘控制器核心采用的是单片机AT89C51，其次利用了光照传感器、键盘显示接口电路以及信号调理电路等外围电路，重点讨论了窗帘自动控制器的设计过程、硬件选用和软件调试等问题，整个控制器在各模块的配合下可实现半自动控制、自动控制、定时控制等功能。
关键词：单片机 光照传感器 信号调理 自动控制

Abstract
Along with economical development, technical progress, people's rhythm of life becomes more and more quick, regarding quality of life the pursue more and more is also high.Highly effective, convenient, the energy conservation more and more is valued people's.Specially moves towards after the integration, the intellectualized transformation along with the electronic technology industry, the people to the home life various aspects all had a higher request.The window blind took in each family life most must lives at home one of things, also needs to meet a people's more comfortable naturally need.But the traditional window blind natural lighting and evades the light question mainly to use is the manual make and break window blind, not only every day early opens the late pass to take the trouble moreover the very many aspect insufficient user friendly, specially villa or multiple room big window blind, not only long, moreover heavy, with when needs the very big strength to be able the switch window blind, is not specially convenient; Therefore the electrically operated window blind arises at the historic moment.
This article introduced the design manufactures the theoretical analysis as well as its manufacture process which a complete automatic window blind controller needs to do.The automatic window blind controller core uses is monolithic integrated circuit AT89C51, next has used the illumination sensor, keyboard demonstration periphery electric circuits and so on connection electric circuit as well as signal recuperation electric circuit, with emphasis discussed the window blind automatic regulator design process, the hardware has selected with questions and so on software debugging, the entire controller might realize functions and so on semi-automatic control, automatic control, timed control in under various modules coordination.
