基于单片机控制电源检测系统电路I基于单片机控制电源检测系统电路摘要随着数字化的快速发展和生活水平的不断提高，人们对电子设备的依赖越来越高，电子设备的持续运行已经成了一种普遍现象，但是在设备持续的运行过程中，总会出现一些无法预料的意外情况发生，比如突然停电，在此过程中，一旦未能及时的做出反应往往会对服务器造成相当严重的损害，面对上述这类情况，本设计中采用了单片机技术针对一旦出现停电现象后，由单片机中的外中断接受到停电信号，并立马回馈。将由单片机自动发送关机指令从而使服务器在安全模式下自动关机的电源监测系统。本次设计将控制电源检测系统电路作为研究对象，以AT89C51单片机为设计核心，设计了一种在市电断电的状态下使系统自动停机的设备主要用于防止因为停电故障对系统造成不必要的损失。本次设计中主要利用到单片机系统，接口转换电路以及服务器三大部分。最终要求能够达到由单片机发出停机信号经过接口转换电路的输送到达服务器，使服务器安全关机，从而保护服务器。关键词：数字时钟；DS1302；LED；AT89C51IIBasedonthesingle-chipmicrocomputercontrolcircuitpowertestsystemABSTRACTWiththerapiddevelopmentofdigitalandthecontinuousimprovementoflivingstandards,peopleishigherandhigherdependenceonelectronicequipment,electronicequipmentruncontinuouslyhasbecomeacommonphenomenon,butintheprocessofcontinuousoperation,thereisalwayssomeunforeseenaccidenthappens,allofasuddenpoweroutage,forexample,intheprocess,oncefailedtotimelyrespondtooftencancauseseriousdamagetotheserver,inthefaceofallthesethiskindofsituation,thisdesignUSESthesingle-chipmicrocomputertechnologyforonceappearblackouts,receivethepowersignalbysinglechipmicrocomputerintheexternalinterruption,andpromptlyfeedback.Sendbysinglechipmicrocomputerautomaticshutdowncommandtotheserverinsafemodeautomaticshutdownofthepowermonitoringsystem.Thiswillcontrolthepowersupplytestsystemcircuitdesignastheresearchobject,withAT89C51asthecoredesign,designamainspowerunderthestateofthesystemofautomaticstopdeviceismainlyusedtopreventbecauseoutagescausedunnecessarylosstothesystem.Mainlyusedtointhedesignofthesinglechipmicrocomputersystemandinterfaceconversioncircuitthreepartsandtheserver.Toachievethefinalrequestmadebysinglechipmicrocomputerdowntimeafterinterfaceconversioncircuitofsignaltransmissiontotheserver,theserversafetyshutdown,thusprotectingtheserver.KeyWords:AT89C51;C++Builder;powersystem;ProtelI目录一、绪论.......................................................................................................11.1项目研究背景与意义.........................................................................11.2国内外发展现状.................................................................................11.3设计主要研究的内容.........................................................................21.4本设计论文的组织形式.....................................................................2二、系统方案设计....................................................................................3三、硬件设计..............................................................................................43.1单片机.................................................................................................43.1.1AT89C51单片机的介绍...........................................................43.1.2单片机的内部结构...................................................................63.1.3单片机接口...............................................................................93.2单片机电源系统..............
