Description
Technical field
The present invention relates to computer server applied technical field, specifically a kind of method of current detecting by power supply and CPU frequency modulation mechanism securing system.
Background technology
Current server product is facing under short-term high load condition, usually uses the CPU overlockin (turboboost) in the short period of time to finish the work process. Thus save the spending buying high-frequency therapeutic treatment for user, it is achieved better product cost. But the overlockin of short-term CPU also can cause the increase of system power dissipation, in some severe situation, the too high overclocking work of CPU may cause Power supply overcurrent protection and cause whole system power failure, and the application of user is interrupted. The appearance of this kind of situation just, greatly reduces the reliability of server, and user's application is safe not.
Summary of the invention
The technical assignment of the present invention solves the deficiencies in the prior art, it is provided that a kind of method of current detecting by power supply and CPU frequency modulation mechanism securing system.
The technical scheme of the present invention realizes in the following manner; the method of this kind of server power supply securing system; comprise server power supply, CPU; current detecting circuit and Rapid Alarm circuit are set in server power supply inside; being provided with buffering electric capacity between described server power supply and CPU, its concrete system protection step is:
1) current threshold of power supply is set by the power consumption number that server system is maximum;
2) power supply internal electrical current detection circuit detects current current value in real time;
3) when current current value is less than current threshold, power supply normal operation;
4) when current current value is more than or equal to current threshold, Rapid Alarm circuit is triggered, the logical overvoltage signal trigger notice of this Rapid Alarm circuit stops overclocking work to CPU, reduces electric current demand, CPU adjusts work at present frequency according to guard signal, simultaneous buffering electric capacity is triggered and starts, and avoids fluctuation of current influential system.
In technique scheme; current detecting circuit realiration is to the overload detection of power supply, and Rapid Alarm circuit directly leads to overvoltage signal and is triggered to CPU, and warning CPU adjusts work at present frequency; thus reduce CPU in time to the demand of power consumption, it is achieved to the protection of server power supply
The size of described buffering electric capacity is by formulae discovery C=P/V1* [T/ (V1-V2)]; P in above-mentioned formula is that power supply estimates maximum power dissipation and the difference of specified power consumption occur; V1 is service voltage, the magnitude of voltage caused when V2 is fluctuation of current, and T is the buffer protection time of design.
Buffer protection function when buffering electric capacity in technique scheme change rapidly occurs as electric current; system can be realized and after frequency reducing, also can not cause, because the fluctuation change of electric current is excessive, machine problem of delaying at CPU, strengthen the reliability of whole server power supply securing system.
The described buffer protection time is 100 �� s.
The useful effect that the present invention compared with prior art produces is:
The method of a kind of server power supply securing system of the present invention, by the current detecting of power supply and CPU frequency modulation mechanism being judged, overload fault occurs in advance in prevention power supply, effectively improves the reliability of server, ensures user's application safety.
Accompanying drawing explanation
Accompanying drawing 1 is the structure schematic block diagram of the present invention.

Embodiment
Below in conjunction with accompanying drawing, the method for a kind of server power supply securing system of the present invention is described in detail below.
As shown in Figure 1; the method of this kind of server power supply securing system; comprise server power supply, CPU; current detecting circuit and Rapid Alarm circuit are set in server power supply inside; buffering electric capacity it is provided with between described server power supply and CPU; as shown in Figure 2, its concrete system protection step is:
1) estimate that maximum power dissipation calculates the maximum current load amount of power supply by system, the actual overload ability to bear according to power supply calculates current value threshold value;
2) power supply internal electrical current detection circuit detects current current value in real time;
3) when current current value is less than current threshold, power supply normal operation;
4) exceed or close to triggering relative alarm signal during threshold value when the current detecting electric circuit inspection of power supply inside goes out current electric current; warning circuit is logical overvoltage signal triggering (such as prochot signal directly; non-low speed data signal path) notify CPU; CPU stops overclocking work, reduces electric current demand; and adjust work at present frequency according to this guard signal; thus reduce the demand to power consumption in time, it is achieved to the protection of server power supply. Simultaneous buffering electric capacity is triggered and starts, and avoids fluctuation of current influential system.
The size of described buffering electric capacity is by formulae discovery C=P/V1* [T/ (V1-V2)]; P in above-mentioned formula is that power supply estimates maximum power dissipation and the difference of specified power consumption occur; V1 is service voltage, the magnitude of voltage caused when V2 is fluctuation of current, and T is the buffer protection time of design.
The described buffer protection time is 100 �� s.
By this buffering electric capacity, it is possible to realize system and also can not cause, because the fluctuation change of electric current is excessive, machine problem of delaying at CPU after frequency reducing, strengthen the reliability of whole server power supply securing system.
