摘　　要：在消费电子领域中,遥控射频控制一般是由硬件完成的,如PT2262和PT2272的配对使用。这种控制方法固化了其对应关系,对遥控设备要求严格配对使用,无法灵活扩展及参与组网控制。为解决这种控制方式带来的问题,采用MicroChip公司的低功耗自身带有E2PROM的PIC12F675单片机,利用C语言完成软件解码及对码程序的编制。其程序在QL200开发板上调试成功。利用此解码程序的解码产品,具有外围电路简单,抗干扰性强,解码速度快,成本低,代码具有可移植性,可以完全替代硬件解码,弥补了硬件解码的缺陷,适用于任何具有PT2262编码格式的遥控器,可直接参与控制等特点。In consumer electronics field, RF remote control is usually done by hardware, such as the paired use of PT2262 and PT2272. This control method solidifies the correspondence and needs severely paired use of the remote control device, so it can＇t be expanded flexibly or participated in the networking control. In order to solve the problems caused by it, the lowpower MCU PIC12F675 produced by MICROCHIP Company with EZPPROM is introduced. This kind of MCU is debugged successfully by QL200 development board, which uses C language to decode and accomplish the coding of the procedure. Compared with the hardware decoding, it is applicable to any remote control with the format of PT2262 and can completely re- place hardware decoding. In addition to this, it has some other properties, such as powerful portability, high decoding speed and lower cost. It can be directly involved in the control and so on.
