摘  要
 在传统的楼宇自控系统中，一般只包括了综合布线、计算机网络、安防、消防、闭路电视监控等子系统。但近年来，随着经济的发展和科技的进步，人们对照明灯具节能和科学管理提出了更多、更高的要求，使教室照明控制系统具有了节能、方便、智能等作用，并能改善工作学习环境，实现多种照明效果，提高管理水平。
 这个以单片机为控制核心的教室照明控制系统，涉及到了系统的设计思想、各芯片的工作原理、元器件的选择、制作等相关问题。该控制系统适用于各种多媒体教室、车站候车室、办公室等场合。它主要由照明控制器、动态传感器、照度传感器、手动控制设备等组成。教室照明智能化设计的目标是要突出照明系统智能化、科学管理和节省能源、节省运营费用的特点。整篇文章以AT89C2051为控制单元，结构简单，成本低廉。

关键词：单片机、教室照明、智能控制系统

Abstract
In the traditional building automation systems, generally including integrated wiring, computer network, security, fire protection, closed circuit television monitoring system. However, in recent years, with the economic development and technological advancement of energy-saving lighting and a more scientific management, a higher demand, so that the lighting control system of the classroom with the energy-saving, convenient and intelligent functions, and can improve the work of the learning environment and achieve a variety of lighting effects, enhance the management level.
This single-chip microcomputer to control the core of classroom lighting control systems, related to the design of the system, the chip''s working principle, the choice of components, production and other related issues. The control system is suitable for a variety of multi-media classrooms, the station waiting room, office and so on. It is mainly from the lighting controller, dynamic sensors, illumination sensors, composed of manual control equipment. Classroom lighting intelligent design goal is to highlight the intelligent lighting system, scientific management and energy conservation, the characteristics of saving operating expenses. AT89C2051 for the whole article to the control unit, simple structure and low cost.

Keywords：micro-control unit, lightening of the classroom, the intelligent control system
