标准文档实用文案自动车窗升降控制器的设计与制作摘要：车窗是汽车必不可少的重要部件，早期的汽车采用传统的手动升降车窗。90年代中期以来，汽车车窗控制器的控制技术发展迅速，电子模块控制形式大量应用于批量装车，并设有安全保护装置。现在许多轿车门窗玻璃的升降使用的是价格低廉、性能稳定的单片机作为集成模块控制器进行控制。据此本次设计也是以STC89C52RC单片机作为核心控制器，L9110芯片为电机驱动，带有温度检测以及状态显示的车窗升降控制器。通过5V小功率电机的正反转、停止以及自动上升功能，模拟车窗的升降以及车辆停车熄火时车窗自动关闭控制功能。采用单片机作控制核心不仅价格低廉而且性能稳定，电路简单。关键词：单片机；直流电机；车窗升降；温度检测标准文档实用文案DesignandmanufactureofautomaticwindowliftcontrollerAbstract:Windowsareimportantandindispensablepartsforautomobiles,earlycarsusedtraditionalmanuallyliftwindow.Sincethemid90,rapiddevelopmentofcontroltechnologyofautomobilewindowcontroller,electroniccontrolmoduleformswidelyusedinbulkloading,andareequippedwithsafetydevices.Nowmanycarwindowglassliftisusedascheap,stableperformanceofthesinglechipmicrocomputerintegratedcontrolmodulecontroller.ThisdesignisalsoSTC89C52RCSCMasthecorecontroller,L9110chipformotordrive,withtemperaturedetectionandStatedisplaywindowliftcontroller.5Vlowpowermotorreverse,stop,aswellasanautomaticrisefunction,whenasimulatingmovementsinthecarwindowandvehicleparkingstallwindowclosesautomaticallycontrolfunctions.Usingsingle-chipmicrocomputercontrolledcorenotonlylowpricesbutstableperformance,simplecircuit.Keywords:microcontroller;DCmotor;windowlift;temperaturedetection标准文档实用文案目录第1章绪论..............................................11.1选题意义...................................................11.2自动车窗升降控制器的发展历程...............................11.3本文主要研究内容...........................................2第2章系统元件选择与论证.................................32.1单片机选择与论证.............................................32.2电机驱动芯片选择与论证.......................................42.3温度传感器筛选与论证.........................................42.4显示器选择与论证.............................................42.5系统方案设计.................................................5第3章硬件电路设计.......................................63.1硬件系统总体设计.............................................63.2STC89C52RC微处理器核心电路...................................63.2.1STC89C52RC单片机简介.........................................63.2.2晶振电路...................................................83.2.3单片机复位电路..............................................93.2.4单片机总体硬件电路设计.......................................93.3电源输入电路................................................103.4L9110电机驱动电路...........................................113.4.1L9110芯片.................................................113.51602液晶显示器电路..........................................123.5.11602液晶显示器.............................................123.5.21602LCD电路设计............................................143.6DS18B20数字温度传感器电路...................................153.6.1DS18B20的主要特征..........................................153.6.2工作原理及应用.............................................153.6.3DS18B20数字温度传感器电路设计................................173.7按键模块设计...............................
