摘　　要：备用电源系统能够有效降低因供配电系统故障导致的播出事故的概率,是广播电视发射台站安全播出的重要保证。以广播电视台发射台站供配电改造工程为例,提出一套改进型备用电源系统设计方案,利用PC817光电耦合器实时检测掉电因子,并以外围接口控制器(Peripheral Interface Controller,PIC)系列单片机作为主控制器来调节切换装置,以实现备用电源系统的自主优化。The backup power system can effectively reduce the probability of broadcasting accidents caused by the failure of the power supply and distribution system,and is an important guarantee for the safe broadcasting of radio and television transmission stations.Taking the power supply and distribution transformation project of radio and television station as an example,an improved backup power system design scheme is proposed,which uses PC817 photocoupler to detect the power failure factor in real time and Peripheral Interface Controller,The PIC series single chip microcomputer is used as the main controller to adjust the switching device to realize the independent optimization of the standby power system.
