Description
Technical field
The present invention relates to power management techniques, relate in particular to a kind of power management method, device and modularized equipment, belong to electronic technology field.
Background technology
Fast development along with network technology, the port density of modularized equipment, bandwidth, speed are more and more higher, the power that causes module to consume is also increasing, simultaneously the business module number of slots amount that is provided with along with modularized equipment is increasing, also further require modularized equipment that bigger system power can be provided, to satisfy the power demand of multi-service module.In order to satisfy this demand, modularized equipment has proposed the scheme of many power supplys cooperating, promptly in a modularized equipment a plurality of power supplys is set simultaneously, thinks that each business module provides power demand.Thereby, in the course of work of an exchange system with many power supplys, a plurality of high capacity, high bandwidth business module, if wherein one or more power supplys break down or by mistake down during electricity, just can be easy to occur the situation of business module power demand greater than power supply output general power, this moment, whole modularized equipment can be electric under the being forced to property because of the power overload, causes professional interruption.Therefore, in order to guarantee normal, the reliability service of modularized equipment machine system, to the management of power, particularly to the power management of the modularized equipment of high capacity, high bandwidth, just seeming is even more important.
In the prior art, in the modularized equipment of high capacity, high bandwidth, system's complete machine occurs, proposed two kinds of power Managed Solutions because of the situation that power supply transships electricity.First kind of power Managed Solution is: in the high capacity of high-power demand, high bandwidth modularized equipment, directly adopt the method for power redundancy backup, by on the basis of normally required primary power, adding backup battery, with break down at primary power or mistake under when electricity, substitute primary power and provide power demand for each business module.This solution is simple to operate, also need not to carry out complicated Power Supply Monitoring and management, but but also inapplicable for the modularized equipment of high capacity, high bandwidth.Itself just is provided with a plurality of power modules the modularized equipment of high capacity, high bandwidth, the increase of backup battery module not only causes the too high of cost of investment, make power supply effectively do not utilized, and when a plurality of backup battery of system power demand, the quantity of power slot position restricts a bottleneck of power redundancy backup scheme beyond doubt.
Second kind of power Managed Solution is business module poll lower electric tube reason scheme.In this scheme, modularized equipment is provided with down electric priority for each business module in advance, when the power available output power is discontented with the pedal system demand, management control module descends business module from high to low in regular turn according to following electric priority, whether business module of every electricity down just satisfies current system requirements to output power of power supply is again once judged, till making that finally output power of power supply satisfies system requirements.This technical scheme is by increasing management control module in modularized equipment, this management control module is according to the following electric priority-level of each business module, guarantee that with the electric down Managed Solution of poll output power of power supply finally can satisfy system requirements, be to have solved problem outwardly, but in the practical application, especially for the system of multi-service module, many power supplys, this technical scheme can't solve the problem of output power of power supply deficiency veritably.Particularly, in the modularized equipment of multi-service module, many power supplys, the each poll of management control module is judged equal needs regular hour of process that whether output power of power supply satisfy business module aggregate demand power, and too much when the quantity of business module and power supply, the time that software polling is judged will be easy to exceed power-supply system causes voltage decline even power down because of overload time.Thereby this technical scheme in actual applications, and the phenomenon that is easy to occur is: when whether software also satisfied the judgement of power condition, machine system but was forced to down because of underpower already.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
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 situations.
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 problem of system power supply output power deficiency 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 by communication bus from each power module and each business module.For power module, following electric policy management module can be obtained Gong the 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 Gong the watt level of each power module, thereby formulating to power with arbitrary power module the time and the various combinations of any several power module, power module can't 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, electric policy management module can also be according to other with each business module corresponding priorities down, in following electric strategy the lower business module of rank being set preferentially 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 has set 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 one power module or inefficacy has taken place several power module, and can't normal power supply the time, electric policy management module can be known this moment because the power supply gross output reduces down, Gong the 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 sets in advance, and according to the following power mode corresponding that is provided with in the following electric strategy with present case, the business module of control appointment descends the electricity operation, thereby by 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 powering 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 sets in advance, promptly the corresponding business module is closed immediately, fast and effeciently the problem of resolution system output power of power supply deficiency.And further, power management method of the present invention also need not to be used as the power module that backs up to additionally increasing 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, by in advance according to Gong the watt level of each power module of system and the power demand size of 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 that pre-establishes, 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 down quick of business module, solved the problem of output power of power supply deficiency 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:
Step 200 according to Gong the watt level of each power module, the power demand size of each business module and the priority level of each business module, is provided with down the electricity strategy;
In the present embodiment, following electric policy management module pre-establishes the step that electricity strategy is set down and specifically can comprise following a few sub-steps:
Step 2000 according to Gong the watt level of each power module, is calculated Gong the watt level corresponding to the various combinations of power module;
Electric policy management module is before the formulation of descending the electricity strategy down, at first need from each power module, to obtain Gong the power information of each power supply by the system bus of modularized equipment, and further, calculate Gong watt level corresponding to the various combinations of a plurality of power modules according to Gong the 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 illustrates, 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, Gong the watt level of corresponding various groups power module.
Step 2001 according to Gong the watt level of the combination correspondence of power demand size, the priority level of each business module and the various power modules that calculate, is provided with the following electricity strategy in the time of can't powering corresponding to the power module of various combinations;
After corresponding Gong the 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 according to the result who calculates and according to 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 power corresponding to the various combinations of power module, down electric policy management module is according to total Gong power of the power module corresponding various combinations, that can't power that calculates, and according to the power demand of each independent business module, at first can determine to close the business module of aggregate demand power for what, thereby during with electricity strategy under formulating, 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 power condition less than the total power demand of the business module of closing.For example if Gong the power of certain power module is 1000W, when the following electricity strategy that is provided with to should power module can't power the time, if correspondence is provided with 3 business module LC1, LC2 and LC3 descends, the power demand summation of these 3 business modules must be greater than the supply power of the power module that can't power, be power demand＞1000W of LC1+LC2+LC3, and 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 power of three business modules that should guarantee to close, preferably, this time electricity strategy should guarantee that also 3 business modules of the LC1, the LC2 that close and LC3 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 is tactful under being provided with, the disabled status that can correspondingly can't power for the identical power module combination of quantity is provided with identical following electricity strategy, promptly is provided with and closes same combination services module.
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 powered, at least need to close business module combination 1, 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.Similarly, 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 201 detects the power supply state of each power module in real time;
Behind the electric strategy of each time that has set 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, in the present embodiment, following electric policy management module can be determined by following two states that detect power module the detection of the power supply state of power module.First state is the state on the throne of each power module, and this situation on the throne refers to specifically whether each power module is normally assigned in the corresponding slot, still by artificial extracting.Particularly, in the practical application, the state on the throne of this power module can flow to down detecting at bit-identify power_present of electric policy management module to each power module by following electric policy management module.In slot, be provided with the power module of the correspondence circuit that detects on the throne whether corresponding to each power module, thereby according to this circuit flow to down electric policy management module at bit-identify power_present, following electric policy management module can be known the state on the throne of each power module.
And second state whether state breaks down for each power module, this situation specifically refer to each power module whether taken place fault, whether can operate as normal.Particularly, in the practical application, the malfunction of this power module can be detected the failure identification power_good that each power module flows to down electric policy management module by following electric policy management module.In system, corresponding to each power module the circuit whether power module to correspondence breaks down and detect can be set all, thereby flowing to down the failure identification power_good of electric policy management module according to this circuit, following electric policy management module can know whether each power module breaks down.And for how whether power module broken down detect, those skilled in the art can be achieved by any known detection method in present technique field, this is not limited in the present invention.
Two states for above-mentioned power module, down electric policy management module is when detecting a certain power module and any above-mentioned state occurred, detect promptly that fault has appearred in a certain power module or when not on the throne, can determine that then this power module can't normal power supply, thereby can carry out following step.
Step 202, if detect arbitrary power module can't normal power supply the time, whether the output power summation that detects the current power module that can power greater than the power demand summation of current all business modules, and execution in step 203 then if not is if then return execution in step 201;
Step 203, according to electricity is tactful down, control corresponding service module is descended the electricity operation;
And preferably, different with a last embodiment is, detect any one or a plurality of power module can't normal power supply the time in the electric instantly policy management module of present embodiment, do not carry out closing of business module immediately, but can again whether the current gross output of system be judged greater than the demand power summation of current all business modules according to before electric strategy is closed the corresponding business module down.And in the present embodiment, the purpose of carrying out this judgement again is: because in actual applications, even system is under the state of operate as normal, can only determine that also system's output power of this moment is enough to satisfy the aggregate demand power of system, and can not determine that this satisfies the degree of aggregate demand power, therefore even detect a power module can't normal power supply the time, can not be therefore definite fully, the power module that this can't normal power supply will cause the power module of remaining normal power supply can't satisfy the power demand of system.
Thereby, in the present embodiment, by when detecting arbitrary power module or any several power module and can't power, again whether the current gross output of system is detected judgement greater than the demand power summation of current all business modules, only when the power module that detects certain inefficacy has caused the system requirements underpower, just the corresponding business module is closed, guaranteed the rationality of time electric strategy execution.
Because the following electricity strategy that sets in advance among the present invention, be according to the power situation of each power module, each business module and according to the priority level system of each business module by following electric policy management module, thereby the closing business module of carrying out according to the electric strategy of this time, also can satisfy by control minimum number, other business module of lowest priority electricity down, to guarantee that power supply output general power is greater than all conditions of the required general power of the business module of electricity down not.
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 sets in advance in real time.
Further preferably, because in actual applications, 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 sets 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 be obtained by the current power demand size information to each business module in real time, with real-time power information according to each business module that gets access to, in real time following electric strategy is upgraded, 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, the following electricity strategy that promptly upgrades needs to satisfy by 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, by in advance according to Gong the watt level of each power module of system and the power demand size of 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 that pre-establishes, 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 down quick of business module, solved the problem of output power of power supply deficiency apace, avoided because of the long appearance that causes electrical phenomena under the complete machine of bus power source overload time.
Further, in the present embodiment also the current power demand information to each business module obtain in real time, with variation following electric strategy is upgraded in real time according to each business module power demand size, thereby guaranteed the accurate rationality of time electricity strategy further, guaranteed the following electricity strategy of setting and the instant coupling of system's current state.
