The development of a real-time surveillance and automatic switching apparatus for use with a double power supply system

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.
