Abstract: A system for automatically providing continuous power supply via standby uninterrupted power supplies (UPSs) includes: a plurality of primary UPSs (10) for providing power supply to electrically powered devices (3) connecting with the primary UPSs; a plurality of standby UPSs (20) connected to the electrically powered devices for providing power supply when there are malfunctions on the primary UPSs; a switch device (6) connected to the standby UPSs for switching over operational states of the standby UPSs; and a monitoring device (4) connected to the primary UPSs, the standby UPSs, the electrically powered devices and the switch device for collecting information from and giving instructions to the primary UPSs, the standby UPSs and the electrically powered devices. The monitoring device includes a programmable monitoring module (40) for collecting information, a shutdown controlling module (42) for giving shutdown instructions, and a switch controlling module (44) for controlling the switch device.

Abstract: A method for automatically saving programs processed in electrically powered devices when a shutdown event occurs. The method is implemented in a power supply system including a plurality of primary UPSs (10) and a monitoring device (4). The monitoring device monitors the primary UPSs and electrically powered devices (3), and sends a shutdown instruction having a time delay when a shutdown event occurs. When the electrically powered devices receive the shutdown instruction, they automatically check whether there are programs being processed therein. If there are such in-process programs, the electrically powered devices automatically save the in-process programs according to pop-out dialog boxes that provide saving prompts. After all the in-process programs are saved and shut down, the primary UPSs and the electrically powered devices are automatically shut down.
