摘　　要：文章研究了红外通信技术在智能家电控制系统中的应用。在该系统中,通过手机向室内控制系统发送消息,控制系统集中解析该消息,然后通过红外向家电开关系统发送开关指令。该系统中由于单片机的串行口已经被PC通信的USB接口占用,因此发送端将P1.6作为串行通信引脚,采用脉时调制方法,波特率为9600 b it/s,由定时计数器1控制;接收端采用外部中断0的方式进行接收。单片机对红外串行信号解析并控制家电继电器开关。In this paper,an intelligent home appliance controller system based on the infrared communication technology is studied.In this system,a message is sent to the indoor control systems by mobile phone,the message is parsed by MCU,and the instructions are sent to the home appliance switching system by infrared communication in this control system.Because the serial port of MCU of control systems is used by USB port,P1.6 port of MCU is used to serial communicate as infrared sending port.Pulse modulation method is used and Baud Rate is 9600 bps which is controlled by timer counter 1.Infrared serial message is received through the port TNT0 of MCU.It is analyzed in MCU and relay switch of home appliance is controlled according to the message.
