本设计采用ATMEL公司的AT89S52单片机和红外遥控技术实现近距离无线通信的软硬件系统。为了使受控设备识别信号，设计一种数字信号编码系统，利用红外线将数字信号调制，而数据的解码则由另外的单片机完成，系统的实现简单。-This design uses ATMEL Corporation AT89S52 MCU and infrared remote control technology to achieve a short distance wireless communications hardware and software systems. Controlled equipment in order to enable the identification signal, the design of a digital signal coding system, using infra-red digital signal modulation, and data from other single-chip decoder completed, the system simple.
