摘 要

社会在不断进步，人类在不断追求，市场在不断变化，高科技应用含量决定着产品发展的新趋势和前景，智能化技术在电子产品领域的应用意义深远。随着电子产品的快速发展，家用电器也越来越偏向智能化，已经应用于实际中的有智能洗衣机，智能电饭锅，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，功能上更强，使用更方便，安全可靠性也更高，最重要的是更节省电能，提高了家用电器的品质。

智能台灯以专门感应人体红外信号的热释电红外传感器为基础，以BISS0001信号处理电路，利用单片机进行处理，以达到便于控制的目的。当房间亮度不够时，且有人在附近时，台灯便会自动点亮，省去了黑暗中摸开关麻烦；当学习时由于靠桌面太近，造成坐姿不正，系统就会提示，以纠正坐姿，防止近视；学习太累了时，趴在桌子上睡会儿时，台灯就会自动熄灭；当无人在时，系统也会使台灯自动熄灭，以达到节省能源的目的。

Title： Intelligent desk lamp design Based on MCU

Abstract

Social progress and in the constant pursuit, the market in a constantly changing, content decided the new trend of development of the product and prospects, intelligent technology in the electronic products in the fields of application of meaning. With the rapid development of electronic products, to intelligent applied in practice of intelligent washing machine, intelligent electric, intelligent induction cooker etc, and the intelligent characteristics, are using single chip microcomputer as the central control unit. Combined with MCU intelligent on the function, use more convenient, safety reliability also infrared sensors, BISS0001 signal processing circuit, using single chip computer processing, in order to achieve the purpose of easy control. When the room and someone when insufficient brightness around, desk lamp will be lighted, tell the darkness touch switch trouble; When learning on the desktop is too close, due to causes posture is not straight, the system will order to correct posture, preventing myopia; Learning too tired, sleep on , it will automatically out; When no one in, the system also can make desk lamp extinguishes, in order to achieve automatic save energy purposes

Keywords：Intelligence desk lamp BISS0001 microcontroller AT89C51
