Abstract
The system comprises at least one master UPS, at least one slave UPS, a monitoring device and a switching device. When the monitoring device has detected out abnormity occurred in master UPS, relevant number of slave UPS is started up by the switching device. When number of master UPS occurring abnormity excesses number of all slave UPS, all slave UPS is started up, and command for shutting down is sent to devices connected to UPS. Then, the said devices can be shut off safely. Finally, all UPS power sources are shut off. The invented system and method gives backing up for maser UPS occurring abnormity.
Description
[technical field]
The present invention relates to a kind of UPS standby system and method that adopts standby UPS.
[background technology]
In recent years, personal computer and Internet fast development.All can see through computer operation by office's all flow processs in the factory building, network make then that continuously various data is shared.In the environment of network system running, the safety of data is one of problem that attracts people's attention most with protection.For computer equipment, the most serious threat is disturbed no more than power supply, the data loss that is caused as voltage low (voltage sag) and power interruptions (power failure).According to (the Computer and Business Equipment Manufacturers Association of american computer cause equipment trade union, CBEMA) the computer equipment electric power quality requirement profile of being drafted is pointed out, the general receptible stable state input voltage range of computer normal power source+6 to-13% between, if the power supply of supplying with exceeds this scope, then computer may produce unusual condition.If supply of electric power is interrupted surpassing 8.33ms, then computer has the anxiety when machine.Therefore, clean and continual power supply just becomes the primary condition of keeping the computer equipment normal operation.(Uninterruptible Power Supply UPS) can be used for providing clean and stable power to uninterruptible power supply provider, so many important equipment (for example server) all can adopt the UPS power supply, to keep electric power continuous.
But UPS battery electric power is limited, be merely able to provide the power supply (deciding) of a bit of time on the power that UPS provided, therefore, UPS associated devices must during this period of time shut down (Shutdown), in order to avoid data loss, in this process, must close opened and do not store as yet the operation archives, make it not lose because of the shutdown of system.In addition, also have a kind of situation,, also can cause that the situation when machine appears in the UPS associated devices when UPS occurs when unusual.Under this kind situation, generally can need to adopt standby UPS to come these equipment is powered.
And in existing UPS redundant technology, when this kind situation occurring, generally only adopt a standby UPS power (promptly adopting many main UPS to add the framework of a standby UPS), though be suitable under some situation of this kind redundant method, but its shortcoming is apparent: when the unusual UPS of appearance outnumbers one, even when enabling this standby UPS, then also can not satisfy the power demands of UPS associated devices fully, and can only close these UPS associated devices and UPS.
So a kind of UPS electric power system need be provided, it can provide many standby UPS, when UPS appearance itself is unusual, can in time switches to from UPS and power; When occurring unusual UPS above one, the standby UPS that also can start respective numbers carries out redundant, even these whole process personnel also can not automatically perform on the computer next door.
[summary of the invention]
Main purpose of the present invention is to provide a kind of UPS standby system and method, when wherein main UPS takes place to can switch to from UPS and power when unusual.
UPS standby system provided by the invention includes at least one main UPS, at least one from UPS, a supervising device and a switching unit, and wherein: main UPS is used for receiving external power source by power line, and powers to the UPS associated devices; Can be in stand-by state or power supply state from UPS,, not power,, can power to the UPS associated devices when when UPS is in power supply state to the UPS associated devices when when UPS is in stand-by state; Supervising device is used for above-mentioned main UPS and monitoring from UPS, and can and send shutdown command from UPS to UPS associated devices and each main UPS, and it includes: whether a programmable monitoring module is used to monitor civil power and whether normally reaches each main UPS and move normally; One shutdown module, after shut down event takes place, can be in certain unused time to UPS associated devices and each main UPS and send shutdown command from UPS itself; One switches control module, is used to control the user mode of switch unit switching from UPS.Switch unit can be complied with the user mode of the order switching of above-mentioned switching controls module from UPS; Wherein supervising device also includes a subscriber interface module, is used to show that each main UPS reaches the current state message from UPS.
This method of UPS redundant provided by the invention comprises the steps: that (a) supervising device monitors network; (b) judge whether the unusual main UPS number of appearance surpasses the number from UPS; (c) when unusual main UPS number occurring and surpass number from UPS, then start powering of respective number from UPS; (d) when the unusual main UPS of appearance outnumbers from the UPS number, then start all from UPS; (e) supervising device sends shutdown command to the UPS associated devices in certain unused time; (f) close these UPS associated devices and close main UPS and from UPS.
Utilize system and method provided by the invention, can carry out redundant unusual main UPS occurring.
