摘要:随着经济的飞速发展，现代化建设的步伐不断加快，人们对生活质量的要求也日益提高，智能化已成为当今建筑发展的主要趋势。就目前的状况来看，住宅，教室，宾馆，酒店，大到商场，体育馆，娱乐中心等多数场所仍在采用人工调节的方式对照明系统进行控制。若采用智能照明控制器，不但可以减少人力，提高生活品质，还具有管理简单，节能环保，控制多样化等优势。

　　　为解决照明控制问题，本文设计了一款居家智能照明控制系统。它可以检测出家中是否有人并在有人的情况下根据照度的变化时时对家中的窗帘和灯进行控制。该系统以AT89S52单片机为控制核心，提出了智能照明控制器的总体设计思路及硬件、软件的设计方案，并对各功能模块的关键技术作了具体描述。本文包含系统硬件电路的设计，整体电路板的分析以及在设计中需要注意的各种问题等。它的主要功能是完成光照度的采集，处理，显示，控制等。论文中包含了电源电路，灯光控制电路，A/D转换电路，继电器驱动电机电路，照度显示电路等。

　　　实验结果表明，该设计具有智能化程度高，应用范围广，占地面积少，可靠性高，稳定性好，操作简单，节能效果显著等优点，能够满足居民家庭的使用需求，在国内市场具有较好的应用前景。

Abstract:Intelligence has become the main trends of contemporary architecture with the rapid developing of economy, accelerating modernization pace, increasing requirements for life quality. The current situation, manual adjustments are still used in most places from residences, classrooms, guesthouses, hotels to shopping malls, stadiums and recreation centers, as a way to control the lighting system. You can not only reduce manpower, improve the quality of life, but also have advantages in simply management, energy-saving and environmental protection, diversification controlling using intelligent lighting controller.

　　　This article designed a home intelligent lighting control system in order to solve the problem of lighting control. It can detect whether anyone at home and control curtains and lights based on the change of illumination at all time. It proposed the overall, hardware and software design ideas for the intelligent lighting controller with AT89S52 as the control unit, detailed described the key technology in each functional modules. This article contains the hardware circuit design, the analysis of the overall circuit board and a variety of problems that need to pay attention in the design. Its main function is to complete the acquisition of the illumination, processing, display, and control. The paper contains a power supply circuit, the lighting control circuit, the A / D conversion circuit, the relay drive motor circuit, illumination display circuit and so on.

　　　The experimental results show that the design has a high degree of intelligence, wide applications, small footprint, high reliability, good stability, easy operation, with remarkable energy savings, etc. It has a good application prospects in the domestic market which can meet the needs of households.
