摘要
随着经济的发展和人们生活水平的提高,电子信息技术越来越广泛的应用的人们的日常生活当中,其中无线遥控开关技术在我们周围已经变得随处可见。电源开关技术是一项非常基础的技术,其中可调遥控电源开关正在逐步地替换传统的手工机械电源开关。可调遥控电源开关是指用发射器发射无线电或者红外线来控制电源开关,无线电和红外线各有优缺点,无线电的优势是可以穿透障碍物,如墙壁、混凝土建筑,遥控距离比较远,缺点是相同频率的无线电信号相互干扰。红外线的优势是相同频率红外线信号不易相互干扰,可以大规模批量生产(如电视机、空调遥控器),无法穿透障碍物,缺点是遥控距离比较近。红外线遥控和无线电遥控原理基本相同,二者区别主要在于信号频段不同,并且无线电适用于远距离遥控,红外线则侧重于近距离遥控。相比之下红外线在日常生活中的应用范围比较广,像彩色电视机遥控器、空调遥控器、DVD遥控器等等一系列家用电器。
本文介绍的可调遥控电源开关的设计,是主要基于PT2262和PT2272设计的红外遥控系统,由采用PT2262设计的红外线发射电路发射一定频率的红外线信号,通过采用PT2272设计的红外遥控接收电路接收信号并进行放大限幅等一系列的处理,之后控制两个双稳态继电器的闭合,从而达到有选择的对电源开关进行控制。

ABSTRACT
With the development of economy and improvement of people's living standard, Electronic information technology is used more and more widely in people's daily life, including wireless remote control switch technology around us have e 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 rate 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 rate 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
