This paper first introduces the basic knowledge and application of smart home, and then expounds the importance of developing infrared remote control automatic curtain, which is an important part of smart home. Then it focuses on the construction and operation instructions of STC89C52, DS1302 composite chip, infrared transmitter and receiver and other machines used in the development of single chip microcomputer infrared remote control system. This paper uses block mode to analyze the hardware circuit design of the whole system, and gives the overall block diagram of the system, power circuit, clock DS1302 circuit, ringing circuit, infrared receiving circuit, motor control circuit and display circuit. The corresponding circuit design is described. Then, the first joke test of the display program uses block docking to write infrared copy program, clock chip DS1302 control program, LCD display program and remote control program. Each unit draws a clear looking balloon image. Finally, the exposure of the clock, manual opening and closing, automatic opening and closing and other control areas have achieved the expected results. Of course, the system needs to be improved in some details.
