基于单片机控制电源检测系统电路  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； AT89C51 Based on the single-chip microcomputer control circuit power test system ABSTRACT With the rapid development of digital and the continuous improvement of living standards, people is higher and higher dependence on electronic equipment, electronic equipment run continuously has become a common phenomenon, but in the process of continuous operation, there is always some unforeseen accident happens, all of a sudden power outage, for example, in the process, once failed to timely respond to often can cause serious damage to the server, in the face of all these this kind of situation, this design USES the single-chip microcomputer technology for once appear blackouts, receive the power signal by single chip microcomputer in the external interruption, and promptly feedback. Send by single chip microcomputer automatic shutdown command to the server in safe mode automatic shutdown of the power monitoring system. This will control the power supply test system circuit design as the research object, with AT89C51 as the core design, design a mains power under the state of the system of automatic stop device is mainly used to prevent because outages caused unnecessary loss to the system. Mainly used to in the design of the single chip microcomputer system and interface conversion circuit three parts and the server. To achieve the final request made by single chip microcomputer downtime after interface conversion circuit of signal transmission to the server, the serve
