电子红外感应水嘴控制器设计与实现 摘 要：红外线是可见光谱中位于红色光之外的光线。尽管肉眼看不到这种光线，但是利用红外线的特性应用到红外线控制器上，并把它运用到电子红外感应水嘴控制器上，不仅可节约大量的水,而且干净卫生。并且还可以运用到红外自动感应灯上，人在灯亮，人走灯灭。 红外感应，通常又叫做电子红外线感应，是利用检测人体发出的红外线信号的方式。这主要需要对红外线信号的放大及处理，选大了，无法关断所控制的红外感应水嘴，选小了，又检测不到人体发出的红外线信号。本文将要介绍的红外线控制开关只是其中的一种应用形式。目前，主要都运用到了自动水龙头、自动感应冲洗器、自动干手器、自动干肤器、自动给皂器、自动恒温淋浴器等中。 关键词：红外线；节约；红外感应水嘴 Electronic infrare dinduction tap controller designand realization Abstract：Infrared is the light which is located outside the red light in the visible spectrum. Although naked eye is blind of this kind of light, but application on the infrared controller using the characteristic of infrared, and utilizes it on the electronic infrared induction tap controller, could not only save the massive water, but also make environment clean and healthy. Moreover it can be utilized on the infrared auto-induction lamp, the lamp became bright when people come and wink when people go. The infrared induction, usually is called electronic infrared to induction, is infrared signal way which sends out using the examination human body. This mainly needed to the infrared signal enlargement and processing, when the process is magnified, it is unable infrared induction tap which shut off controls, when the process is shrink, it is unable to examine the infrared signal which sent out by the human body. This article is going to introduce the infrared controlling switch is only one kind of application form. At present, its applications are mainly on the automatic water cock, the auto-induction flusher, the automatic hand and the skin drying apparatus, for the soap, the automatic constant temperature showers automatically in and so on. Key words:Infrared;saves;the infrared induction tap 目 录 1 绪论 1 1.1 电子红外感应水嘴控制器的发展 1 1.2 红外线特性及电子红外感应水嘴控制器的优点 1 1.3 电子红外感应水嘴控制器的流行现状 2 1.4 电子红外感应水嘴控制器的可行性分析 2 1.5 设计系统的功能和意义 3 2 模拟电路 4 2.1 模拟电路概述 4 2.1.1 模拟电路的发展 4 2.1.2 模拟电路的特点 4 2.2 集成IC器件 4 2.2.1 集成IC的发展 4 2.2.2 集成IC的分类 6 2.3 PN结的形成与半导体BJT 6 2.3.1 PN结的形成的概述 6 2.3.2
