【正文】 常生活當(dāng)中，其中無線遙控開關(guān)技術(shù)在我們周圍已經(jīng)變得隨處可見。 電源開關(guān)技術(shù)是一項(xiàng)非?；A(chǔ)的技術(shù)，其中 可調(diào) 遙控電源開關(guān)正在逐步地替換傳統(tǒng)的手工機(jī)械電源開關(guān)。紅外線的優(yōu)勢(shì)是相同頻率紅外線信號(hào)不易相互干擾，可以大規(guī)模批量生產(chǎn)（如電視機(jī)、空調(diào)遙控器），無法穿透障礙物， 缺點(diǎn)是遙控距離比較近。 相比之下 紅外線在 日常 生活中的應(yīng)用范圍比較廣，像彩色電視機(jī)遙控器、空調(diào)遙控器、 DVD遙控器等等一系列家用電器。 關(guān)鍵字： 紅外線 ； 遙控； PT2262； PT2272； 雙穩(wěn)態(tài) 繼電器 目錄 Ⅲ ABSTRACT With the development of economy and improvement of people39。s daily life, including wireless remote control switch technology around us have bee visible. Power switch technology is a very basic technology, and wireless remote control power switch is gradually replacing the traditional manual mechanical power switch. Wireless remote control power supply switch is a transmitter for transmitting radio or infrared to control a power switch, a radio and infrared has its advantages and disadvantages, radio’s advantage is that can perate obstructions, such as walls, concrete construction, the remote control distance is far, disadvantage is the same frequency radio signal interference. Infrared’sadvantage is that the same frequency infrared signals are not easy to interfere with each other, so it can be mass production (such as TV, air conditioning remote control), can perate obstacles, disadvantage is the remote control distance closer. Infrared remote control and wireless remote control principle is basically the same, the two major difference lies in the different signal frequency band, and the radio is suitable for remote control, infrared remote control is focused on the short distance. By contrast of infrared in daily life in a relatively wide range of application, such as color TV remote control, remote control for air conditioner, DVD remote control and so on a series of household appliances. This paper introduces the remote control power supply switch design, is mainly based on the PT2262 and PT2272 design of infrared remote control system, by using PT2262 design for infrared transmitting circuit transmits the infrared signal of certain frequency, through the use of PT2272 design of infrared remote control receiving circuit receives the signal and amplifying limiting and a series of processing, after controlling for a bistable relay closed, so as to achieve the power switch control. Key Words: Infrared。 PT2262。 bistable relay 目錄 Ⅲ 目錄1 引言 .............................................................. 1 2 整體設(shè)計(jì)方案及分析 ................................................ 2 設(shè)計(jì)思路分析 ....................................................
