Design and Implementation of Intelligent Curtain System Basedon 51 Single Chip ComputerAbstract:As science and technology continue to innovate and improve,people's quality of life alsocontinues to improve,it seems that people slowly rely on smart products.Due to the rapid developmentof the Internet of Things technology,the concept of smart home has long been accepted by people.Many homes and enterprises already have these facilities,which have great advantages over ordinaryequipment.However,it does not only exist in life,production,military,management and other fields.From this point of view,the Internet of Things technology is more and more widely used,and its role isbecoming more and more important.This article comprehensively describes the design and implementation of the intelligent curtainsystem.In this system design,it is mainly composed of the STC89C51 microcontroller as the minimumsystem,light detection circuit,infrared control circuit,power supply module,key module,LCD1602liquid crystal display module,stepper motor drive module,AD analog-to-digital conversion module andso on.The light intensity value collected by the system through the light sensor under light,and then thecollected analog quantity is converted into a digital signal by AD modulus,and the 51 single-chipmicrocomputer is used as a control unit to realize the opening and closing of the curtain according to thereal-time light intensity.The entire system is completed under the cooperation of the division of labor ofeach module,which realizes the internal contact of manual control,automatic control,infrared control,timing control and other functions.Among them,the key control and infrared control aresemi-automatic controls,and the illumination detection and timing control are automatic controls.LCD1602 liquid crystal display is used to display the current time,light intensity value,semi-automatic,automatic module and other information.Keywords:Smart Home,Smart Curtain,SCM,Stepper Motor
