With the rise of the intelligent home concept, the infrared remote control technology becomes an important bridge for connecting users and various intelligent devices, and the development of home intellectualization is further promoted. However, the conventional unidirectional communication infrared remote control method has obvious defects. Without a feedback mechanism, the remote control cannot know whether the controlled device successfully receives and executes the control instruction. When the instruction execution fails due to signal interference, equipment failure and the like, a user cannot obtain feedback in time and can only repeatedly try to send the instruction, so that the control efficiency and reliability are reduced. Meanwhile, when a plurality of continuous control instructions are processed, because of lack of effective management on instruction execution results, it is difficult to accurately judge the execution condition of each instruction, and control confusion may occur.
