Embodiment
Below in conjunction with accompanying drawing the present invention is made further detailed description.
Fig. 1 is the redundant power backup control device of the embodiment of the invention and the synoptic diagram that is connected of supply unit.In the embodiment of the invention, when using the supply unit 10 with redundant power module to supply power as load system 20, redundant power backup control device 30 is used for the power supply of supply unit is controlled.
The redundant power backup control device 30 of one embodiment of the invention is as shown in Figure 2, and control device 30 comprises detecting unit 310, is used to detect the power consumption threshold value that whether is lower than setting by the current power consumption of the load system 20 of supply unit 10 power supplies; Control module 330; Be used for when the current power consumption that detecting unit 310 detects load system 20 is lower than the power consumption threshold value of setting; Thereby the shutdown command as the power module of redundant power backup that sends in the powered-down device 20 is closed said power module as the redundant power backup, the for example power module 2 in the supply unit among Fig. 1 10.
In embodiments of the present invention, control device 30 can be to be arranged in 20 minutes with load system, also can be arranged on the inside of load system, can also be arranged in the supply unit.Load system can be server system, disc array system etc.
Need to prove that among Fig. 1, supply unit 10 only is to be used to illustrate for the 1+1 power configuration.The 1+1 power configuration, referring to load system has a power module power supply to get final product operate as normal, but in configuration, is two power modules, and one of them power module backs up as redundant power.Supply unit 10 also can be other power configuration modes, like 2+1,3+1 power configuration etc.
In an optional embodiment; Control device also comprises alternating current input monitoring unit; Be used to carry out following function: the alternating current input status of monitoring power supply device 10 starts the said power module that backs up as redundant power when monitoring alternating current input in taking place when unusual at the appointed time.In another optional embodiment; The alternating current input monitoring unit of control device 30 is used for the alternating current input status of monitoring power supply device 10, when monitor alternating current input start in taking place when unusual at the appointed time said as the redundant power backup power module and will be just draw high the said power module that backs up as redundant power at the current loading of current supply module.
In optional embodiment; Control device 30 also comprises: the functional verification unit; Be used to read the data message of said supply unit; Judge according to said data message whether said supply unit meets specification requirements and whether support the cold standby technology, if whether the current power consumption of the said load system of then said detection is lower than the power consumption threshold value of setting.

Be that Baseboard Management Controller BMC in server, the server describes one embodiment of the invention as redundant power backup control device 30 for example below with the load system, with reference to figure 3.
In this embodiment; Through the embedded software management of BMC, after the server system start, BMC reads the technical specification information of power supply through power management bus PMbus; Comprising data messages such as the specification of power supply, model, power, and the data message that can support the cold standby technology.BMC judges whether the data message that reads meets specification requirements then, if meet, then BMC starts redundant power backup control.Differentiate the power consumption levels of server system through the power consumption parameter of sensor acquisition server system, thereby control the work of power supply.
For example dispose the server (disposing two modules that rated power is 800W) of a cover 800W redundant power device; Collect the common power consumption of server about 400W; This moment, two modules of redundant power device were born the 200W power consumption respectively, and load is merely 25% for rated power is the power module of 800W.Redundant power backup control method according to the embodiment of the invention; When BMC detects under 50% condition that system power dissipation is lower than the power supply rated disspation; Then BMC is through the PMbus bus; Power module 2 to as the redundant power backup sends ps off shutdown command, forces to turn off the power module 2 that backs up as redundant power in the supply unit.At this moment, only by power module 1 supply 400W electric power, load is positioned at about 50% supply unit.Following table is the data of typical efficient power load efficiency value.
Table 1
| 10% |
20% load | 50% load | 100% load | |
| 230VAC/50HZ | 80％ | 88％ | 92％ | 88％ |
