摘要
红外线遥控是目前使用最广泛的一种通信和遥控方式,由于其具有结构简单、体积小、功耗低、功能强、成本低等特点,因而广泛应用于彩电、空调机、CD/VCD、录像机家用电器设备及其工业控制中。随着现在人们生活中家电日益增加的需要,使用红外遥控器也越来越频繁。因为各种红外遥控器编码格式不同,使得各种红外遥控器不能兼容。经常需要更换遥控器,这也给人们生活带来了不便。单片机的迅速发展使这一问题得到了很好的改善。
在此设计一种以AT89C52单片机为核心的学习型红外遥控器,通过测量红外一体化接收头输出信号,并原样地记录其输出脉冲宽度,然后保存在单片机中,最后利用单片定时器中断产生38 kHz载波信号,以软件代替了硬件,节约了资源。该学习型红外遥控器能成功地学习各种红外遥控设备的编码,并通过38 kHz载波发送学忆信号。实现了对各种各样红外遥控的学习,从而实现了真正的自学习遥控。

ABSTRACT
Infrared remote control is the most widely used means of munication and remote control, due to its simple structure, small size, low power consumption, strong function, low cost, and therefore widely used in color TV, air conditioning, CD / VCD, VCR household appliances and industrial control equipment. With people now living in the growing need for home appliances, use infrared remote control is also increasingly frequent. Because of various different encoding format infrared remote control, making all kinds of infrared remote control can not patible. Often need to replace the remote control, which brings inconvenience to people's lives. SCM has been developed rapidly so that this problem has been well improved.
In this design a kind of learning as the core AT89C51 infrared remote control, first by measuring the output signal of Integrated IR receiver head, and stood to record the output pulse width, and then stored in the SCM, Finally, single-chip timer interrupt to generate 38 kHz carrier signal,
