教室LED日光灯节能控制设计 摘 要 基于当前对教室灯光控制方法的的了解，尤其是教室灯光的智能控制方面的发展现状，分析了教室灯光智能控制的原理和实现方法，提出了基于单片机的教室灯光智能控制系统的设计思路，并在此基础上设计了智能控制系统的硬件装置和相应软件。 该系统以AT89C52单片机作为控制装置的智能部件，采用热释红外人体传感器检测人体的存在，采用光敏电阻构成的电路检测环境光的强度;根据教室合理开灯的条件，系统通过对人体的存在信号和环境光强弱的识别和智能判断，完成对教室照明回路的智能控制，避免了教室用电的大量浪费。系统还具有报警功能。单片机软件采用C语言编制，采用模块化结构设计、条理清晰、通用性好，便于改进和扩充。 该系统具有体积小，控制方便，可靠性高，专用性强，性价比合理等优点，可以满足各类大、中专院校教室灯光控制的要求，很大程度的达到节能目的。 关 键 词：  THE DESIGN OF SCHOOL LED LIGHT ENERGY SAVING CONTROL ABSTRACT Based on the current realize of school lighting control method, especially the classroom light intelligent control development present situation, analyses the classroom light intelligent control theory and implement method, is proposed based on single-chip shool light intelligent control system design, based on the design of intelligent control system hardware and corresponding software. This system to control device of AT89C2051 single chip microcomputer as intelligent parts, using thermal infrared sensor detect the existence of of human body, using photosensitive resistance of circuit testing environment light intensity, Reasonable according to the shool light conditions, the system through the light intensity signal and the environment for the presence of the human body identification and intelligent judgment, complete the classroom light intelligent control circuit,, to avoid the classroom a large amount of waste of electricity. System also has the alarm function. Single-chip microcomputer software compiled using C language, using modular design, clear structure, good versatility and facilitate improved and expanded. This system has the advantages of small size, high reliability and easy control, the price is reasonable, strong specificity etc, can satisfy all kinds of big, secondary colleges shool light control requirements, to a great degree of energy-saving objective.
