摘　　要：　针对不间断供电的需求,提出了一种智能式双电源供电系统实时监控和自动切换装置的优化解决方案。该装置采用单片机最小系统,通过采样、比较和判断,可对电网电压进行实时监控,并能在常用电力电源出现故障时,自动将用户电路切换到备用电源,以保证对用户的不间断供电。Aimed at the need of power supply without any break,this paper puts forward an optimized conception dealing with a kind of realtime surveillance and automatic switching apparatus desinged for working with an intelligent double power supply system by using a singlechip computer to perform sampling,comparision and determination so as to fulfil the monitoringcontrol task.When poweroff occurs,the apparatus can automatically transfer the customer electric circuit to the standby power supply,thus keeping the customer power supply still working without a break.
