基于FPGA的红外家居遥控系统

Infrared Remote Controller Based on FPGA

介绍红外家电遥控的码流和几种类型的编码方法,采用89S51单片机和现场可编程门阵列(FPGA)开发一款自学习式通用家电遥控器。通过自制的简易遥控教练器与接收器实现对原本无遥控功能的电灯、电扇、窗帘等追加红外遥控功能。通过Girder软件实现对电脑的遥控。通过对电脑、电视、VCD等家用电器的测试,证明该遥控系统学习性能良好,操作简易,有效遥控距离可达5~7m。

This paper presents the model of code flow and some encoding types of remote infrared control signals.A self-taught infrared remote controller which is based on FPGA and 89S51 microcontroller is designed.It is superadded the function of remote control for apparatus such as lamps,electric fans,curtains and so on.We can control the PC computer remotely as expediently as the television through the software of Girder.The results indicate that the controller has good learning performances and it is easy to telecontrol within 5～7 meters.
