红外遥控编码在单片机系统中的处理

如今，利用红外遥控传输较小的数据量来控制电器设备的应用已经非常广泛，对各种红外遥控器发出来的红外编码进行采集和处理就成了众人非常关心和急需解决的问题。仔细分析了多种遥控器所发红外编码的特点及其规律，详细地阐述了利用单片机系统对家用电器遥控器发出来的红外编码进行学习、存储、传输和再生的原理，在此原理的指导下，研制出了适用于学校电化教学的“CATV双向控制系统”。通过该系统长时间的稳定运行，证明了文中所述原理的正确性。

The Disposal to the Code of Infrared Telecontrol in the Singlechip System

Today, the application, using infrared telecontrol to transmit a few data to control electric equipment,is so popularized. The problem, picking and processing the infrared code which sent by the various telecontroller, being watched out and solved eagerly by many people. We analyzed carefully the characteristic and its law of the infrared code which sent by the kinds of telecontroller. The principle, using the singlechip system to learn,store,transmit and restore the infrared code which sent by the telecontroller of electric appliance, is also detailedly expounded in this paper. By guiding of the principle, we developed the CATV bilateral control system which applied in school for electrified teaching. The long time reliable run of this system proofed the correctness of the principle which expounded in this paper.
