摘　　要：意外断电对基于PC平台的信息发布系统容易造成损害,本文给出了一种断电保护电路设计方法。本设计采用STC15F00单片机为主控制器,断电时通过检测电源和PC状态,切换PC供电电源实现对系统的保护,对其原理设计进行了详细描述。该电路成本低,体积小,适合内嵌到系统中,大大提高了信息发布系统的稳定性。Unexpected power outage is easy damage to the information release system based on PC platform. Power protection circuit design is given by the paper. The design takes STC15F00 as the main controller,when the power is off, through the detecting power and PC state, the design switches PC power supply to protect the system. Detailed schematic design is given. This circuit has the advantages of low cost, small size. It is suitable for embedded system and can improve information publishing system stability.
