摘要
红外遥控是一种无线、非接触控制技术,具有抗干扰能力强,信息传输可靠,功耗低,成本低,易实现等显著优点,被诸多电子设备特别是家用电器广泛采用。它是把红外线作为载体的遥控方式。红外线遥控是利用近红外光传送遥控指令的,~。用近红外作为遥控光源,是因为目前红外发射器件(红外发光管)与红外接收器件(光敏二极管、三极管及光电池)~,在近红外光波段内,二者的光谱正好重合,能够很好地匹配,可以获得较高的传输效率及较高的可靠性。
本次设计的红外遥控器是一个由PT2262产生地址代码,由红外发射管发射,再由红外接收管接收,使用数电和模电的知识设计红外解码器。

Abstract
The infrared remote control is a wireless, non-contact control technology. It has anti-interference ability, reliable information transmission, low power consumption, low cost, easy to realize significant advantages. And many electronic devices, it is widely used, in particular for household appliances. It is as a carrier of the infrared remote control mode. Infrared remote control is the use of near-infrared light to send mands, and ~ wavelength of near-infrared light. As a remote light source in the near infrared, because light peak wavelength infrared emitting devices (infrared LED) and luminous infrared receiver devices (photosensitive diodes, transistors and photovoltaic cells) generally ~ . Band in the near-infrared light, both the spectrum just coincidence, can be well matched. Possible to obtain a higher transmission efficiency and high reliability.
Infrared remote control of the design is an address code generated by the PT2262, launch tube by infrared, infrared receiver receives the knowledge to use the number of electric and analog electronics design infrared decoder.
