introduces the automatic induction tap based on infrared reflection principle, when people or things are near, automatic generating control signals, so that the electromagic valve to automatically open source circuit is closed。系統(tǒng)電路設(shè)計簡單實用,可以廣泛用于商場、學(xué)校、辦公大樓等人員密集場所。 與傳統(tǒng)供水設(shè)施相比,能夠提高水資源的使用效率。據(jù)報道我國是一個水資源短缺的國家,若按人均水資源量計算,人均占有量只有 2500立方米,約為世界人均水量 的四分之一,世界排 110 位。成都理工大學(xué)工程技術(shù)學(xué)院畢業(yè)論文 自動控制開關(guān)的 設(shè)計與仿真 作者姓名: 李 陽 專業(yè)名稱: 電氣工程及其自動化 指導(dǎo)教師: 李自成 副教授 許麗 助教自動控制開關(guān)的 設(shè)計與仿真 I 摘要 在 21 世紀(jì),自動控制在各個領(lǐng)域都得到了廣泛的應(yīng)用,自動控制開關(guān)作為自動控制的核心其作用是非常重要的,本文就主要討論了基于紅外線技術(shù)的自動感應(yīng)水龍頭的設(shè)計與仿真。 隨著經(jīng)濟(jì)的不斷發(fā)展,人們對淡水的需求不斷增加,不久的將來,淡水資源緊缺將成為世界各國普遍面臨的嚴(yán)峻問題。 本文介紹的全自動感應(yīng)水龍頭基于紅外線反射原理, 當(dāng)人或事物靠近時,自動產(chǎn)生控制信號,使電磁閥得電吸合從而自動打開水源;反之則自動關(guān)閉水源。使用方便,且由于不需要用手接觸水龍頭,避免了病菌的傳播。 關(guān)鍵詞 : 傳感器 自動控制 紅外線 自動開關(guān) 自動控制開關(guān)的 設(shè)計與仿真 II Abstract In twentyfirst Century, the automatic control in various fields have been widely used in automatic control, automatic control switch as the core of its function is very important, this article mainly discusses the technology based on infrared automatic induction faucet design and simulation. With the constant development of economy, people demand for fresh water is increasing, the near future, fresh water resources shortage will bee world each country generally faces serious problems. According to the report of our country is short of water resources in the country, according to the per capita water resources calculation, per capita is only2500 stere, about the world39。 and automatically shut off the water supply. Compared with the traditional water supply facilities pared, can improve water use efficiency. Easy to use, and because it does not need the hand contact with water, to avoid the spread of the virus. The circuit design of the system is simple and practical, can be widely used in shopping malls, schools, office buildings and other personnelintensive places.
