The first administration module comprises a DCMI module and the first control module, the second administration moduleComprise the 2nd DCMI module and the second control module, certain the first administration module and the second administration module are alsoCan comprise some other circuit.
On the first administration module, can also be provided with election module, this election module is used for carrying out two managementThe principal and subordinate of DCMI module and control module election between module, the first administration module is by this election moduleDetermine that whether a DCMI module and the first control module be all effective. The first administration module specifically can lead toCross following mode determine a DCMI module and the first control module whether all effective: first, first pipeWhether reason module detects the first control module and powers on. The first control module adopts the system voltage power supply of 12V,Can pass through Long-distance Control power-on and power-off, a DCMI module adopts the power supply of 5V standby voltage, in modularizationWhether management equipment is also power supply under holding state, therefore do not need to detect DCMI module and power. TheWhether one administration module detects the first control module and powers on, if the first control module powers on, and the first managementModule detects the first control module and whether a DCMI module is all ready. The one DCMI moduleCan export respectively ready ready signal with the CPU of the first control module, the first administration module passes throughWhether the Ready signal that detects each module output is effective, judges that whether each module is ready. If firstControl module and a DCMI module are all ready, and the first administration module is determined a DCMI mouldPiece and the first control module are all effective, and two modules on the first administration module are all in normal work shapeState.
If a step 102 DCMI module and the first control module are all effective, the first administration moduleFrom the second control module of the first control module and the second administration module, electing the first control module is master controlMolding piece is so that the second administration module is adjusted the second control module for from control module, and according to election resultsAdjusting a DCMI module is main DCMI module, and correspondingly, the second administration module is by the second controlModule is adjusted into the 2nd DCMI module of adjusting self from control module for from DCMI module; Or,It is from controlling that the first administration module is elected the first control module from the first control module and the second control moduleModule is so that the second administration module is adjusted the second control module is main control module, and adjusts according to election resultsA whole DCMI module is from DCMI module, and correspondingly, the second administration module is by the second control mouldPiece is adjusted into and adjusts the 2nd DCMI module after main control module is main DCMI module.
The first administration module is determining that the DCMI module of self and the information of the first control module haveIn the situation of effect, first, from the first control module and the second control module, carry out principal and subordinate's election, firstIt is master control molding that administration module is elected the first control module from the first control module and the second control modulePiece, the second control module is from control module. Wherein, the second control module is positioned at the second administration moduleUpper, the second administration module also comprises the 2nd DCMI module, the second administration module and the first administration module itBetween main and standby relation each other. For the principal and subordinate of the control module between two administration modules or DCMI moduleElectoral machinery is prior art, can conduct an election by any one method of the prior art, and the present inventionDo not limit.
Below will simply introduce a kind of electoral machinery, suppose that the first control module powers on and ready after (Ready is effective), carry out according to the following steps: the first step: the first administration module detects the second control moduleWhether whether (opposite end) exists, effectively sentence by the present signal that detects the second control module outputDisconnected. If do not exist, be single tube reason template pattern, the first control module is main control module. If exist,Carry out second step: detect the second control module and whether export master signal, if the second control module is defeatedGo out master signal, the second control module has been main control module, the first control module be adjusted into fromControl module, this kind of pattern is generally hot intercalation model. If the second control module is not exported master signal,Carry out the 3rd step: whether readyly detect the second control module, whether effectively detect ready signal,If the second control module is offhand ready, illustrate that the second control module fault cannot normally work,The first control module becomes main control module, if the second control module is ready, judges groove bit-identifyWhether signal soltid signal is 1, if 1, illustrate that the second control module is main control module, if notBe 1, the second control module is from control module, and the first control module is main control module. Above onlyBe a kind of simply introduced control module principal and subordinate's election method, can also realize by other electoral machinery.
From the first control module and the second control module, elect the first control module at the first administration moduleAfter main control module, output master signal, the second administration module by the second control module be adjusted into fromControl module. Meanwhile, the first administration module adjustment the one DCMI module is main DCMI module, secondAdministration module is being adjusted into the second control module from control module, adjust the 2nd DCMI module be fromDCMI module, thus make the first control module on the first administration module and a DCMI module allBe main, and the second control module on the second administration module and the 2nd DCMI module be all from, ensuredOn same administration module, the principal and subordinate of DCMI module and control module is consistent. When the first administration module is as masterAdministration module, the second administration module is as from administration module, the DCMI module on two administration modules andThe information of control module is all obtained by the first administration module, and the information in synchronizing process is only in administration modulePortion transmits, and does not need to transmit by the backboard between two administration modules, makes communicationMore convenient. Meanwhile, DCMI module and HOST module share a set of election mechanism, makeSimpler in circuit design.
In the present embodiment, the first administration module may be also from control module by the first control module election,The second control module is main control module, and the first administration module is adjusted a DCMI mould according to election resultsPiece is from DCMI module, and correspondingly, the second control module is being adjusted into main control by the second administration moduleAfter module, adjusting the 2nd DCMI module is main DCMI module. Thereby make on the first administration moduleOne control module and a DCMI module be all from, and the second control module on the second administration module andThe 2nd DCMI module is all main, has ensured the master of DCMI module and control module on same administration moduleFrom unanimously.
In the present embodiment, elect from the first control module and the second control module at the first administration moduleThe first control module is main control module or from control module, and election results are notified to firstDCMI module, the state and first that makes a DCMI module adjust oneself according to election results is controlledThe state of module is identical, and even the first control module is main control module, and a DCMI module is mainDCMI module, if a DCMI module is from control module, a DCMI is also from DCMIModule. Particularly, the first administration module can be notified a DCMI module, example by the mode of interruptingIf, the first administration module is after electing the first control module and being main control module, by the first control moduleMaster signal setting be 1, and send interrupt notification signal, a DCMI to a DCMI moduleModule is received after interrupt notification, initiatively reads the value of the master of the first main control module, and by selfMaster value is also set to 1, and such the first control module and a DCMI module are all main, due toThe master signal value of one control module output is that 1, the second administration module is by the second control module of oneselfBe adjusted into from control module, and adjust the 2nd DCMI module for from DCMI module.
It should be noted that, the first administration module is identical with the function of the second administration module, firstWhen administration module conducts an election, the second administration module is also in election, two administration modules export respectively withLower status signal: slotid, mater, ready, present signal, wherein, Slotid is groove position information,Groove position 1 or groove position 2 for what identify administration module insertion; Master signal is principal and subordinate's id signal,Be used for informing that other these administration modules of board are main management modules or from administration module. Ready signal is pipeReason module ready signal, whether ready for informing other this administration module of administration module; PresentFor there is signal in signal; Be used for informing that whether other these administration modules of administration module are in place. Two modules existIn election process, carry out the mutual of information mutually by above-mentioned signal, the first administration module is according to the shape of selfThe status signal of state and the second administration module conducts an election, and the second administration module is also according to the first management simultaneouslyThe status signal of module and the state of self conduct an election.
The method that the present embodiment provides, the first administration module is carrying out principal and subordinate while electing, first to the first controlModule and the second control module are carried out principal and subordinate's election, are electing after result, and the first control module adjusts theOne DCMI module is consistent with the principal and subordinate of the first control module, be all main or be all from, correspondingly, theTwo control modules, according to the election results of the first control module, are adjusted the 2nd DCMI module and of selfThe principal and subordinate of two control modules is consistent, thereby makes DCMI module and control module on same administration modulePrincipal and subordinate consistent.
It should be noted that, in prior art, generally control module is responsible for each mould of whole equipmentThe management coordination work of piece, and DCMI module is mainly used in providing data center's management interface, therefore,The priority of control module is higher than the priority of DCMI module, so the first administration module is being ledDuring from election, first control module is carried out to principal and subordinate's election.
Fig. 4 is the flow chart of the embodiment of the method two of administration module principal and subordinate election of the present invention, and embodiment bis-existsOn the basis of embodiment mono-, further describe this electoral machinery, as shown in Figure 4, the present embodiment providesMethod comprise step:
Whether step 201, detection the first control module power on.
If the first control module powers on, perform step 202, if the first control module does not power on, carry outStep 203. In this step, owing to adopting the mode of remote power feeding, there is a DCMI in the first control moduleFirst power on, and situation about powering on after the first control module, therefore, first the first administration module will detectWhether one control module powers on. Particularly, the first administration module receive first control module sendWhen principal and subordinate elects instruction interrupt signal, detect the first control module and whether power on, certainly, the first management mouldPiece also can be real-time detect, or a sense cycle is set, for example within 20 seconds, detect once, thisInvention does not limit this. Because the power-on and power-off of the first control module are not an operation frequently,If adopt real-time detection mode will take cpu resource, and the mode that adopts interrupt notification then to detect,Can effectively avoid the waste of resource.
Whether step 202, detection the first control module and a DCMI module be all ready.
If the first administration module detection obtains the first control module and a DCMI module is all ready,Execution step 204, if the first control module and/or a DCMI module are not ready, i.e. the first controlAny one in molding piece or a DCMI module breaks down, and performs step 205.
Step 203, detect a DCMI module whether ready.
In the situation that the first control module does not power on, only has a DCMI module job, the first managementModule, before a DCMI module and the 2nd DCMI module are carried out to principal and subordinate's election, need to checkWhether one DCMI module is ready. If a DCMI module is ready, perform step 206,If a DCMI module is not ready, perform step 207.
Step 204, from the second control module of the first control module and the second administration module, elect firstControl module is main control module so that the second administration module is adjusted the second control module for from control module,And be main DCMI module according to election results adjustment the one DCMI module; Or, from the first control mouldIn piece and the second control module, electing the first control module is from control module so that the second administration module adjustmentThe second control module is main control module, and is from DCMI according to election results adjustment the one DCMI moduleModule, correspondingly, the second administration module adjusts after the second control module is adjusted into main control moduleTwo DCMI modules are main DCMI module.
After the first administration module is main control module by the first control module election, and adjust a DCMIModule is main DCMI module, and the second administration module is adjusted the second control module for from control module, phaseYing Di, the second administration module is being adjusted into the second control module from control module, to adjust self secondDCMI module is from DCMI module, or, the first administration module by the first control module election for fromAfter control module, adjusting a DCMI module is from DCMI module, and the second administration module adjustment certainlyThe second control module of body is main control module, and correspondingly, the second administration module is by the second control moduleBeing adjusted into and adjusting the 2nd DCMI module after main control module is main DCMI module, thereby makes same pipeIn reason module, the principal and subordinate of DCMI module and control module is consistent. Concrete grammar can be with reference in embodiment mono-Describe, repeat no more here.
Step 205, election the first control module are from control module so that the second administration module adjustment secondControl module is main control module, and is from DCMI mould according to election results adjustment the one DCMI modulePiece, correspondingly, the second administration module adjusts second after the second control module is adjusted into main control moduleDCMI is main DCMI module.
Any one in the first control module or a DCMI module is not ready, illustratesOne administration module breaks down, when the DCMI mould on any one administration module in two administration modulesPiece or control module break down, and this administration module can only be from administration module, therefore, and the first managementModule can only be from administration module, and the first administration module does not need to carry out principal and subordinate's election, directly self is establishedBe set to from administration module, said method has solved the in the situation that of DCMI module or control module fault,How to carry out two principal and subordinate's elections between administration module.
Step 206, from a DCMI module and the 2nd DCMI module, elect a DCMI moduleBe main DCMI module or from DCMI module, then perform step 208.
Do not power in the first control module, and in the effective situation of a DCMI, carry out this step, thisStep is the electoral machinery of DCMI module under holding state, and the first administration module is from a DCMI mouldIn piece the 2nd DCMI module, carry out principal and subordinate's election, election the one DCMI module be main DCMI module orPerson is from DCMI module, and electoral machinery can adopt existing any one electoral machinery.
If a step 207 DCMI module is not ready, elect a DCMI module for fromDCMI module.
Do not power in the first control module, and in the not ready situation of a DCMI module, explanationThe one DCMI module failure, the first administration module is from administration module, is somebody's turn to do from administration moduleDCMI module is from DCMI module.
Step 208, judge whether to receive that the principal and subordinate that the first control module sends elects instruction interrupt signal.
If the first administration module receives that the principal and subordinate that the first control module sends elects instruction interrupt signal, if theOne DCMI module first powers on, after the first control module, power on, the first control module after powering on, meetingSend principal and subordinate to the first administration module and elect instruction interrupt signal, if the first administration module receives that principal and subordinate electsInstruction interrupt signal, returns to execution step 201, restarts election flow process. If do not receive, principal and subordinate electsInstruction interrupt signal, finishes election process, and this modularized equipment enters normal operating condition.
The method that the present embodiment provides, a point situation has been described in all cases, and the first administration module carries outThe method of principal and subordinate election is all effectively in situation, first right in a DCMI module and the first control moduleIn the first control module and the second control module, carry out principal and subordinate's election, electing the first control module is master controlMolding piece or be from control module, adjusts a DCMI and the first control module master according to election resultsFrom being consistent, correspondingly, the second administration module is also adjusted the 2nd DCMI module and the second control modulePrincipal and subordinate is consistent, thereby has ensured that the principal and subordinate of DCMI module on same administration module and control module is consistent., illustrated in DCMI module under holding state, and a certain module is while breaking down, how meanwhileCarry out the scheme of principal and subordinate's election, the scheme that principal and subordinate is elected is more complete.
