基于51单片机的智能窗帘控制系统

ABSTRACTWith the rapid development of science and technology,people have higher and higherrequirements on the current living standard,air environment and living quality.So the smarthome system slowly entered the people's sight.Mainly to provide convenience for people'slives.Realize the science and technology home,wisdom home and green home in people'sconcept.As a module in smart homes,smart curtains have unlimited development potential.Under this background,this article has studied the intelligent curtain control system,hopingto play a certain guiding significance.This article describes the control system of smart curtains in detail,describes the designprinciples and application assembly of smart curtains in detail,and lays a solid foundation forpromoting the wide application of smart curtains.In the process of writing this paper,it ismainly divided into five parts to describe.In the first part,this paper first introduces thebackground and significance of the subject,and conceives the overall design idea through thebackground and significance.The second part describes the overall design of the program indetail.The STC89C51 microcontroller is used to design the intelligent curtain control system.The LCD1602 liquid crystal display is used as the display module.A stepper motor is used todrive the curtain movement.The third part is in terms of hardware design,the realization ofintelligent functions mainly depends on the STC89C51 microcontroller,and the design ofperipheral circuits is mainly based on motors,buttons,and photometric circuits.In the entireintelligent curtain control system,the functions of automatic and manual control system arerealized through the light intensity acquisition module,stepper motor module,and key inputmodule.The fourth part mainly describes the design of the software part of the intelligentcontrol system in detail.It mainly uses the relevant software to realize the programming of thesystem program,thereby ensuring the realization of the function of each module of the system,and strengthening the connection of all links within the system.The fifth part is the assemblyand debugging of the hardware.The method of welding is used in the assembly of the circuit.In the debugging circuit,the method of debugging while installing is adopted.Through thefour steps of inspection before power-on,power-on observation,unit circuit test,and jointdebugging of the whole machine,the performance of all circuits fully meets the designrequirements.Finally,a physical object based on the 51 single-chip intelligent curtain controlsystem is obtained.This physical object supports two modes,manual mode and light controlmode.Use five buttons to switch modes,set light thresholds and open and close curtains.KEYWORDS:Intelligent curtain;single chip microcomputer;stepping motor
