1、专科毕业设计(论文)题目教室智能照明控制系统设计摘要达到节能目的。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。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,采用光敏三极管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。系统还具有多种
2、报警功能;同时还采用了软/硬件的“看门狗”技术等抗干扰措施。单片机软件采用汇编语言编制,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,很大程度的关键词:人体;红外线;传感器;自动控制;热释电TheclassroomintelligentlightingcontrolsystemdesignABSTRACTCurrentlylightintelligentcontrolsystemsarenotefficientlyusedinthec
