红外线控制自动水龙头的设计摘 要本论文介绍了利用红外发射与接收电路设计自动水龙头的原理与设计方案。电路设计简单，使用方便，同时更利于节能，“节能降耗”是我们追求的目标。传统的水龙头、卫生间供水等设施，使用起来不是特别方便，而且很浪费水资源。在这个基础上，我设计了自动供水电路。不仅可以节约用水，而且外形美观，使用起来也很方便。红外线控制自动水龙头由红外发射电路、红外接收放大电路、控制电路、电磁阀、电源等组成。当人或事物靠近时，自动产生控制信号，继电器动作，使电磁阀得电吸合从而自动打开水源；反之则自动关闭水源。[关键词]传感器；红外线；自动控制AbstractThis paper describes the use of infrared transmitter and receiver circuit design theory and automatic faucet design. Circuit design simple, easy to use, but also conducive to energy, "energy saving" is our goal. Traditional taps, toilet water and other facilities, is not particularly easy to use, but also a waste of water resources. On this basis, I have devised an automatic water supply circuitry. Can not only save water, but also pleasing in appearance, is also very easy to use. Infrared control Automatic faucets from the infrared transmitter, infrared receiver amplifier circuit, control circuit, solenoid valve, power supply etc.When people or things around, theAutomatically generated control signal, relay, so that was electric solenoid valve to automatically open the pull-water; Otherwise it would automatically shut down water supply.[Key words] sensor, infrared,automatic control目 录第一章绪论 61.1 引言 61.2 国外进展方向与现状 6第二章元器件方案 82.1 传感器 82.1.1 CCD 图像传感器 82.1.2 电容式传感器 82.1.3 超声波传感器 92.1.4 光电传感器 92.2 发光二极管（LED）102.3 接收管 11第三章红外线控制自动水龙头设计 133.1 水龙头的构成与传感器控制 133.2 系统组成方框图 133.3 红外反射式光电传感器特性与工作原理 143.4 红外线控制自动水龙头的工作原理 153.4.1 红外线水龙头控制电路系...
