Pick This paper first introduces the basic knowledge of smart home and its application prospect, and then expounds the significance of developing infrared remote control automatic curtains, which is a very important part of smart home. Then, the structure principle of the integrated chip STC89C52, DS1302 chip, infrared transmitter and receiver and other hardware used in the development of infrared remote control curtain system controlled by single chip microcomputer is emphatically introduced. In this paper, the hardware circuit design of the whole system is analyzed in block mode, and the overall block diagram of the system, power supply circuit, clock DS1302 circuit, ringing circuit, infrared receiving circuit, motor control circuit and display circuit are given respectively, and the corresponding circuit design is expounded. Then, the writing ideas of the software are described, and the block mode is adopted. The writing ideas of the infrared decoding program, the clock chip DS1302 control program, the LCD display program and the remote control program are written respectively. Each module has drawn its block diagram, which looks clear at a glance. Finally, through simulation and debugging, the design of clock, manual opening and closing curtains, automatic opening and closing curtains and other control aspects basically achieved the expected purpose. Of course, the system needs to be constantly improved and improved in some details. Key words: clock chip, single chip microcomputer, infrared ray, curtain.
