编 号本科生毕业设计（论文）题目： 基于 51 单片机的智能台灯 的设计与应用 物联网工程 学 院 微电子学 专 业二〇一四年六月摘 要随着社会在不断进步，高科技含量决定着产品进展的新趋势和前景，智能化技术在电子产品领域的应用意义深远.电子产品的快速进展，家用电器也越来越智能化，目前已经应用于实际中的有智能洗衣机，智能空调，智能电磁炉等，而所用的智能化家用电器都用一个共同的特点，都是利用单片机作为中央控制单元.结合了单片机的智能家用电器和普通家用电器相比，使用更方便，安全可靠性也更高，效率更高，最重要的是它们为能源节约提供巨大的帮助.智能台灯以专门感应人体红外信号的红外传感器为基础，这意味着仅当有人的时候，红外传感器才输出一个信号，经放大处理后达到单片机的输入门限电压，单片机开始运行，台灯自动点亮.当人离开的时候，单片机控制台灯自动关闭，以达到节约用电的目的 .此外，单片机内的计时器将会计时一小时，在此之前假如人未离开，计时结束后，台灯上的蜂鸣器将会响起，提醒使用者应该离开休息一会儿，同时台灯将自动关闭，这个功能可以帮助保护使用者的视力.关键词：单片机；智能台灯；红外传感器；信号放大ABSTRACTWith the progress of society, the development prospect of new products depends on its high-technology content. As electronic products become more and more advanced, some domestic appliance seems ‘intelligent’ to some extent, and some technology has been applied into real life at present, such as smart washing machine, smart air-condition and intelligent induction cooker, etc. All of them have a common characteristic, that is, they all use a MCU （ Micro Controller Unit ） as their ‘brain’. Comparing with those household appliances which have no MCU, they are more convenient, safe and efficient. More important, they make great effort to the project of electrical energy saving.The intelligent desk lamp depend on a kind of infrared sensor which can perceive human beings, that means, it will output a signal when there is someone near it, this signal w...
