Embodiment
Fig. 1 is the computer system synoptic diagram of one embodiment of the invention.Please with reference to Fig. 1, computer system 100 comprises power supply unit 110, power-supply controller of electric 120 and mainboard 130_1～130_n, and wherein n is a positive integer, and with the design of computer system and client's demand and difference.Power supply unit 110 couples power-supply controller of electric 120 and mainboard 130_1～130_n.Power-supply controller of electric 120 couples mainboard 130_1～130_n.Mainboard 130_1～130_n is under the situation of not start; Power supply unit 110 can produce standby power STP; And mainboard 130_1～130_n can convert standby power STP into each a mainboard corresponding standby voltage; Wherein mainboard 130_1～130_n can comprise electric pressure converter (not illustrating), standby power STP is converted into a plurality of standby voltages.
Generally speaking, power supply unit 110 can couple a power supply backplane (not illustrating), and the power supply (for example standby power STP or primary power MP) that power supply unit 110 is produced through this power supply backplane is supplied to mainboard 130_1～130_n respectively.Power-supply controller of electric 120 can be disposed on the above-mentioned power supply backplane.When mainboard 130_1～when the 130_n block-by-block was connected to power supply backplane, mainboard 130_1～130_n can receive standby power STP.At this moment, mainboard 130_1～130_n can transmit mainboard identification code ID_1～ID_n respectively to power-supply controller of electric 120.Power-supply controller of electric 120 can see through the quantity of counting mainboard identification code ID_1～ID_n and learning mainboard 130_1～130_n after receiving mainboard identification code ID_1～ID_n.
The standby power STP that is provided by power supply unit 110; Be generally the power supply of a little electric current; Be under standby or the off-mode with mainboard 130_1～130_n in computer system, mainboard 130_1～130_n is provided the last required standby voltage of electronic component that is driven by standby power STP.But; When the quantity of mainboard 130_1～130_n is increasing; The required magnitude of current of its standby voltage also can increase, and might be in shutdown or following mainboard quantity that can drive of holding state (driving number to call the mainboard standby in the following text) in mainboard above standby power STP.Therefore, possibly cause the electronic component that is driven by standby power STP on some mainboard can't operate or fault, make mainboard to start shooting.
So, learn the quantity of mainboard 130_1～130_n at power-supply controller of electric 120 after, whether can compare this quantity greater than preset value, wherein this preset value can drive number for being equal to or less than the mainboard standby.When this quantity is not more than preset value, represent standby power STP to be enough to drive all mainboards, this moment, power-supply controller of electric 120 did not have any action.When this quantity during, represent standby power STP can't drive all mainboard 130_1～130_n smoothly greater than preset value.At this moment, power-supply controller of electric 120 must be looked for other power supply and replace standby power STP, to be supplied in the mainboard partly, lets mainboard 130_1～130_n driven smoothly whereby.Therefore, power-supply controller of electric 120 can produce power supply enable signal PON to power supply unit 110.Power supply unit 310 produces primary power MP after receiving power supply enable signal PON, and when power supply is ready, produces power supply ready signal PGD.After power-supply controller of electric 120 receives power supply ready signal PGD, produce control signal (for example CTL_1) to mainboard 130_1～130_n at least one of them.
Then; Be example with mainboard 130_1 earlier; When mainboard 130_1 received the control signal CTL_1 that power-supply controller of electric 120 produced, mainboard 130_1 all accepted the primary power MP of power supply unit 110 outputs no matter be in start, shutdown or holding state; And convert primary power MP into a standby voltage, so that the electronic component that is driven by standby power STP can normal operation.Because the voltage quasi position of standby power STP and primary power MP is identical, so mainboard 130_1 can utilize above-mentioned electric pressure converter (not illustrating) to convert a plurality of standby voltages into.(for example during CTL_2～CTL～n), its action is same as described above, so repeat no more and mainboard 130_2～130_n is receiving control signal.
In addition; The quantity that transmission controls signal to mainboard depends on the quantity of mainboard 130_1～130_n and the difference that the mainboard standby drives number; For example the quantity of mainboard is 7, and it is 4 that the mainboard standby drives number, just has 3 mainboards and receives control signal; And these mainboards can convert primary power MP into standby voltage, so that mainboard can drive smoothly.And control signal the mainboard that will transmit, can select the mainboard of normal start.Whereby; Can avoid the too much problem that can't drive that causes of mainboard quantity; And select to transmit the mainboard that controls signal to normal start, more can reduce the switching times that mainboard selects primary power MP or standby power STP are converted into a plurality of standby voltages, to prolong the life-span of on-off element.
On the other hand, power-supply controller of electric 120 can be distinguished at a distance from the signal between each mainboard 130_1～130_n, is not more than mainboard standby driving number in this first quantity with mainboard 130_1～130_n and explains.Following in this situation; Because standby power STP is enough to drive all mainboards; So when mainboard 130_1～130_n all was in the state of shutdown or standby, mainboard 130_1～130_n all can receive standby power STP and be converted into the required standby voltage of each mainboard.When mainboard 130_1 is activated when being in open state, can export motherboard power supply enabling signal MSP_1.When power-supply controller of electric 120 receives motherboard power supply enabling signal MSP_1, produce power supply enable signal PON.When power supply unit 110 receives power supply enable signal PON, produce primary power MP, and when power supply is ready, produce power supply ready signal PGD.And power-supply controller of electric 120 is sent to mainboard 130_1 (like PGD_1) with power supply ready signal PGD after receiving power supply ready signal PGD.And mainboard 130_1 then begins to carry out boot program when receiving power supply ready signal PGD_1, so that mainboard 130_1 comes into operation.This moment, promptly this mainboard 130_1 was under the open state, and the standby voltage of this mainboard is provided by the primary power MP of power supply unit 110.Whereby, the startup of mainboard 130_1 can not have influence on mainboard 130_2～130_n.
Then, when mainboard 130_2 is activated when being in open state, can transmit motherboard power supply enabling signal MSP_2 to power-supply controller of electric 120.At this moment, because the primary power MP and the power supply ready signal PGD of power supply unit 110 produce,, power-supply controller of electric 320 directly power supply ready signal PGD is sent to mainboard 130_2 (shown in PGD_2) so understanding.And mainboard 130_2 then begins to carry out boot program when receiving power supply ready signal PGD_2, so that mainboard 130_2 comes into operation.At this moment, the startup of mainboard 130_2 can not have influence on mainboard 130_1,130_3～130_n.After this, the action that remaining mainboard (for example 130_n) starts can according to above-mentioned analogize learn, then do not give unnecessary details at this.And the order that above-mentioned mainboard starts is in order to explanation, does not limit the embodiment of the invention with this.
In addition, when the quantity of mainboard 130_1～130_n drives number greater than the mainboard standby, power-supply controller of electric 120 can directly produce power supply enable signal PON, causes power supply unit generation primary power MP and power supply ready signal PGD.At this moment, when mainboard 130_1 is activated when being in open state, can transmit motherboard power supply enabling signal MSP_1 to power-supply controller of electric 120.And power-supply controller of electric 120 can be sent to mainboard 130_1 by transmission power supply ready signal PGD_1, so that mainboard 130_1 begins to carry out boot program and comes into operation.And all the other mainboards (be activated when being in open state like 130_1～130_n), its action is identical with above-mentioned mainboard 130_1, so do not give unnecessary details at this.What deserves to be mentioned is, if mainboard is to convert standby power STP into standby voltage when being in shutdown or holding state, when being in open state, then be to convert primary power MP into standby voltage.Whereby, power-supply controller of electric 120 can prevent the interference of signal between mainboard, avoids mainboard to produce maloperation.
What deserves to be mentioned is; Above-mentioned power-supply controller of electric 120 can utilize complex programmable logic device (complex programmable logic device; CPLD) or able to programmeization interruptable controller (Programmable Interrupt Controller PIC) realizes.Whereby, can simplify the design of circuit, and reduce the cost of circuit construction.
In sum, the computer system of the embodiment of the invention when the quantity of mainboard during greater than preset value, can produce power supply enable signal and control signal.When power supply unit receives the power supply enable signal, produce primary power.When mainboard receives control signal, then convert primary power into this mainboard corresponding standby voltage.Whereby, but Dynamic Selection part mainboard converts primary power into these mainboards corresponding standby voltage, and avoids standby power can't drive all mainboards, the System Operation mistake that is caused.In addition, computer system utilizes complex programmable logic device or programmable interruptable controller to realize power-supply controller of electric.Whereby, can simplify the design of circuit, and reduce the cost of circuit construction.
