1、中文摘要单片机渗透到我们生活的各个领域，几乎很难找到哪个领域没有单片机的踪迹，电灯已是千家万户的必需生活用品，当夜晚来临时，人们摸黑去开灯，非常不方便，而当离开时，人们又经常忘记关灯而造成巨大的能源浪费。本研究针对教室灯光的控制方法，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，并在此基础上开发了智能控制系统的硬件装置和相应软件。主要是以红外热释电处理芯片BISS0001和单片机组成的红外传感控制电路。其原理是：以人体红外辐射（波长为9.5um）为传感信号，当人体在台灯的范围内且
2、环境光强较弱时，自动感应开灯，省去黑夜摸灯的麻烦；当人离开台灯传感器检测范围，自动感应关灯。采用LM393电压比较器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信号的识别和智能判断，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。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。关键词：人体感应，教室灯，单片机，智能化共页第页ABSTRACTMicrocontrollerpenetrated intoeveryaspectofourlives,
