基于物联网的无线红外转发器的设计

Design of Wireless Infrared Repeater Based on Internet of Things

设计一款集成多种空调品牌和型号的红外遥控指令并具有学习功能的无线红外转发器。红外转发器采用了意法半导体Cotex-M3内核的STM32F100C8处理器,使用一体化红外接收头HS1838进行红外解码,并通过433 MHz频率的无线网络进行命令和数据的双向传输。可用于基于物联网的智能住宅的远程控制系统。用户可通过网络发送指令控制家中的红外转发器,进而远程控制带红外接口家用电器。实验结果证明这是一种高效的物联网红外转发器应用方案。

A wireless infrared repeater is developed.The repeater supports a variety of infrared remote control commands for air conditioning which are of different brands and models,and have ability of self-learning infrared remote control commands.The processor STM32F100C8 based on Cotex-M3 core and produced by STMicroelectronic is used in this design.The infrared receiver HS1838 is employed to decode infrared signal,transmit commands and data by 433 MHz frequency through wireless network bi-directly.It can be applied to remote control system of smart house based on Internet of things.Users can control the wireless infrared repeater far from their house by sending commands over the Internet,and then remotely control their household appliances which have infrared interfaces.The experimental results show that it is a highly effective applications of IR repeater based on Internet of things.
