简易自来水开关控制电路 摘 要 随着微电子技术和自动控制技术的迅速发展，红外线控制技术在工业控制领域内得到十分广泛地应用。 全自动人体红外线感应开关适用范围本产品适用于走廊、楼道、仓库、车库、地下室、洗手间等场所的自动照明、抽风等用途。真正体现楼宇智能化及物业管理的现代化。 功能特点 1、 基于红外线技术的自动控制产品，当有人进入开关感应范围时，专用传感器探测到人体红外光谱的变化，开关自动接通负载。人不离开且在活动，开关持续导通；人离开后，开关延时自动关闭负载，人到灯亮，人离灯熄，亲切方便，安全节能。 2、 具有过零检测功能：无触点电子开关，延长负载使用寿命。 3、 应用光敏控制，开关自动测光，光线强时不感应。 本文是利用红外线感应技术设计的一种既省时省力又能节约水资源的一种自来水开关控制电路。它主要是由红外线发射装置、时间延时电路采用NE555作为核心芯片实现的。 关键词 : 红外线 、 发射装置、感应装置、时间延时 、 自动控制电路。 Abstract Along with the microelectronic technology and the automatic control technologys rapidly expand, the infrared control technology obtains in the industrial control domain very widely applies. Completely automatic human body infrared induction switch applicable scope this product is suitable for corridor, corridor, warehouse, garage, basement, washroom and so on uses and so on place automatic illuminations, convulsion. Manifests the building intellectualization and the estate management modernization truly. Function characteristic: 1st, based on infrared technology automatic control product, when some people enter the switch induces the scope, the special-purpose sensor surveys the human body infrared spectrum the change, the switch automatic connection load. The human does not leave, and in the activity, the switch continues the breakover; After the human leaves, the switch time delay automatic shut-off load, is bright the human to the lamp, the human extinguishes to the lamp, kind convenient, safe energy conservation. 2nd, has the zero crossing detection function: Non-contact electronic switching, extension load service life. 3rd, the application photosensitive control, the switch automatic light measuring, the optical fiber is strong when does not induce. Along with product automation development, the people when face each kind of life demand, not only time-saving reduces effort, moreover may the nurse resources. Therefore, the automatic control products appearance and widely applies into the history the necessity. The com
