Fig. 1 is the process flow diagram of power management method embodiment one of the present invention, and as shown in Figure 1, present embodiment specifically comprises the steps:
Power management method of the present invention is applied in the modularized equipment of many power supplys, multi-service module.Particularly; In modularized equipment of the present invention; Increase and be provided with one and be used for when output power of power supply does not satisfy the power aggregate demand of business module; Control corresponding business module is descended the following electric policy management module of electricity, and the electric policy management module of this time is connected with each power module and each business module.Further; For fear of occurring because of when power supply breaks down; Whether electric policy management module need descend electricity to carry out interim poll judgement to each business module down; Thereby the phenomenon that causes because of electricity under the long complete machine that causes of bus poll judgement time, in the present invention, the electric policy management module of this time also is used for: when modularized equipment carries out initial setting up; According to the power information that from each power module and each business module, gets access to, be the following electricity strategy of business module setting in advance corresponding to various situation.
By in modularized equipment, setting in advance electricity strategy down; When the system output power of modularized equipment is not enough; Electric policy management module can be according to this time electricity strategy that sets in advance down; Apace the corresponding business module is closed down immediately; Thereby solved the not enough problem of system power supply power output apace, avoided the generation of above-mentioned phenomenon.
Particularly; In modularized equipment of the present invention; Because following electric policy management module is connected with each power module and each business module; Thereby in the initialization setting up procedure, following electric policy management module can get access to its pairing power information through communication bus from each power module and each business module.For power module, following electric policy management module can be obtained the supplied watt level information of each power module from each power module, specifically refers to the watt level information that each power module can provide; And for business module; Electric policy management module then can be obtained power demand size information and the priority level information of each business module from each business module down, refers to that specifically each business module is used to keep important the priority level information of own operate as normal desired power size information and each business module.
After getting access to these information, following electric policy management module can be descended the formulation and the setting of electricity strategy according to the information that gets access to.Particularly; Owing to known the supplied watt level of each power module; Thereby formulating to supply power with arbitrary power module the time and the various combinations of any several power module, power module can't supply power the time during the pairing strategy of electricity down; Electric policy management module can learn that should control the total big or small business module for what of power demand at least descends electricity down, so that current power supply output general power can satisfy total power demand size of remaining all business modules.Further; Owing to known the priority level of each business module; Thereby when the above-mentioned electricity down of formulation strategy, all right basis of following electric policy management module is other with each business module corresponding priorities, in following electric strategy, the lower business module of rank is set preferentially and closes; Thereby the business module that guarantees professional outbalance can be closed relatively laterly, and then guarantees the continuity of important service.
Behind the electric strategy of each time that is provided with in advance corresponding to the various failure conditions of power module; Electric policy management module can be in the normal course of operation of modularized equipment down; Detect the power supply state of each power module in real time; Specifically refer to detect each power module and whether can export the predetermined electric power size effectively, thereby whether to needs carry out closing of business module according to electric strategy down and judge according to testing result.
Particularly; If following electric policy management module detects any power module or inefficacy has taken place several power modules; And can't normal power supply the time, following electric policy management module can be known this moment because the power supply gross output reduces, and the supplied general power of system can't satisfy the power demand of all business modules; So this electric at present policy management module reads the following electricity strategy that is provided with in advance; And according to the following power mode corresponding with present case that is provided with in the following electric strategy, the business module of control appointment descends the electricity operation, thereby through the lower business module of closed portion priority level; Make current system's output general power can satisfy total power demand of remaining business module, avoided total system because of not enough cause following of power supply.
Than existing poll judgment mechanism; Power management method of the present invention breaks down or other reasons and can't supplying power at power module; When causing system's output power not enough, need not each business module to be carried out again the poll decision operation of power temporarily, but can be according to the following electricity strategy that is provided with in advance; Promptly the corresponding business module is closed immediately, fast and effeciently the not enough problem of resolution system output power of power supply.And further, power management method of the present invention also need not the extra power module that increases as backup in modularized equipment, thereby has also overcome the too high and inapplicable defective of cost in the existing redundancy backup scheme.
The power management method of present embodiment; Through in advance according to the power demand size of the supplied watt level of each power module of system and each business module; Formulate the following electric priority policy of the business module that need close when corresponding each power module breaks down; Detect one or more power modules break down and cause current can power supply the general power of output during less than the general power of current business module needs; According to the following electricity strategy of formulating in advance, close the lower business module of assigned priority, thereby need not to increase extra power supply for modularized equipment; And need not when output power of power supply is not enough, each business module to be carried out on the basis of poll decision operation of power temporarily; Just realized the electric down fast of business module, solved the not enough problem of output power of power supply apace, avoided because of the long appearance that causes electrical phenomena under the complete machine of bus power source overload time.
Fig. 2 is the process flow diagram of power management method embodiment two of the present invention, and as shown in Figure 2, present embodiment specifically comprises the steps:
In the present embodiment, following electric policy management module is formulated the step that electricity strategy is set down in advance and specifically can be comprised following a few sub-steps:
Electric policy management module is before the formulation of descending the electricity strategy down; At first need from each power module, obtain the supplied power information of each power supply through the system bus of modularized equipment; And further, calculate supplied watt level corresponding to the various combinations of a plurality of power modules according to the supplied power information of each power module that gets access to.Particularly; Because for modularized equipment with multi-power module; The failure mode of power module can have multiple situation, multiple combination; Only comprising 3 power modules with simple modularized equipment is that example is explained, the power-fail pattern that only comprises the modularized equipment of 3 power modules can comprise: all lost efficacy three types failure mode of the independent failure mode of 3 power modules, the failure mode of any two power modules and 3 power modules.Thereby under formulating before the electric strategy, following electric policy management module need at first calculate under the various integrated modes, the supplied watt level of corresponding various groups power module.
After corresponding the supplied watt level of the various combinations that calculate power module; Electric policy management module can be provided with tactful corresponding to the following electricity of various failure modes particularly based on the result who calculates and based on the power demand size of each business module that gets access to from each business module and the priority level of each business module down.According to the information of obtaining or calculating, when following electric policy management module is provided with in the formulation of descending the electricity strategy, need and meet some requirements according to certain principle.
Particularly; Situation about can't supply power corresponding to the various combinations of power module; Down electric policy management module is according to total supplied power of the power module corresponding various combinations, that can't supply power that calculates; And, at first can confirm to close the business module of aggregate demand power, thereby with when formulating that electricity is tactful down for what according to the power demand of each independent business module; The corresponding business module of closing minimum number that is provided with is with the aggregate supply power of the power module that guarantees the to supply power condition less than the total power demand of the business module of closing.For example if the supplied power of certain power module is 1000W; When the following electricity strategy that is provided with to should power module can't supply power the time; If correspondence is provided with 3 business module LC1, LC2 and LC3 and descends; The power demand summation of these 3 business modules must be greater than the supply power of the power module that can't supply power, i.e. power demand＞1000W of LC1+LC2+LC3, and also 3 business modules should satisfy the minimum number of above-mentioned condition.
Further; On this basis; According to the priority level of each business module, following electric policy management module should guarantee that also in following electric strategy, the business module of closing being set is the minimum business module of priority level, thereby can laterly be interrupted with the important service that guarantees modularized equipment.3 business modules with the above-mentioned LC1 of closing, LC2 and LC3 are that example describes equally; When electricity is tactful under being provided with; This time electricity strategy is except the supply power summation of power demand summation greater than the power module that can't supply power of three business modules that should guarantee to close; Preferably, 3 business modules of this time electricity strategy LC1, LC2 and LC3 that also should guarantee to close are for can satisfy business module above-mentioned condition, that priority level is minimum.
Need to prove; In the practical application; If the supply power of each power module in the module device all equates; When electricity was tactful under being provided with, the disabled status that can correspondingly can't supply power for the identical power module combination of quantity be provided with identical following electric strategy, i.e. same combination services module is closed in setting.
Particularly, be that example describes there to be 3 power modules in the modularized equipment with identical supply power.Suppose on the basis of power demand that fully takes into account each business module and priority level; When a power module with constant power can't be supplied power, need close business module combination 1 at least, as shown in the table; In the following electric strategy that is provided with; No matter when which power module in the power module 1,2,3 can't normal power supply, all can be provided with and close same business module combination 1, satisfy the power demand of all business modules of residue with the output power that guarantees the remaining power supply module.Likewise, no matter when which two power module in the power module 1,2,3 can't normal power supply, also can in electric strategy down, be provided with and close same business module combination 1 and business module combination 2, to satisfy the power demand of surplus lines module.

Step 204 is obtained the current power demand size information of each business module in real time;
Step 205 according to the current power demand size information of each business module that gets access to, is upgraded the following electric strategy that is provided with in advance in real time.
Further preferably; Because in practical application; Along with the variation of the working environment of each business module or the influence of other objective factors, the power demand size of business module also might immediately change, thereby in the present embodiment; Unreasonable or the incorrect phenomenon of following electricity strategy that is provided with in advance that changes and cause for fear of the power demand that occurs because of business module; The following electric policy management module of modularized equipment can also with the real-time power information according to each business module that gets access to, be upgraded following electric strategy through in real time the current power demand size information of each business module being obtained in real time; Thereby guaranteed the following electricity strategy of setting and the instant coupling of system's current state, guaranteed time tactful reasonable correctness of electricity.
Particularly; In this step; Electric policy management module can be with reference to the same principle that electricity strategy time institute's foundation is set down down; Following electric strategy is upgraded, and the following electricity strategy that promptly upgrades needs to satisfy through control minimum number, other business module of lowest priority electricity down equally, guarantees that power supply output general power is greater than all conditions of the power demand of the business module of electricity down not.
The power management method of present embodiment; Through in advance according to the power demand size of the supplied watt level of each power module of system and each business module; Formulate the following electric priority policy of the business module that need close when corresponding each power module breaks down; Detect one or more power modules break down and cause current can power supply the general power of output during less than the general power of current business module needs; According to the following electricity strategy of formulating in advance, close the lower business module of assigned priority, thereby need not to increase extra power supply for modularized equipment; And need not when output power of power supply is not enough, each business module to be carried out on the basis of poll decision operation of power temporarily; Just realized the electric down fast of business module, solved the not enough problem of output power of power supply apace, avoided because of the long appearance that causes electrical phenomena under the complete machine of bus power source overload time.
