The server power supply protecting system comprises a server power supply and a CPU (central processing unit), wherein the inside of the server power supply is provided with a current detection circuit and a quick alarming circuit, and a buffer capacitor is arranged between the server power supply and the CPU. The method comprises the following specific system protecting step of preventing the overload faults of the power supply through the current detection of the power supply and the prejudging of a CPU frequency modulation mechanism. Compared with the prior art, the method of the server power supply protecting system has the advantages that the reliability of the server is effectively improved, and the application safety of a user is ensured.
Description
Technical field
The present invention relates to the computer server applied technical field, a kind of by the current detecting of power supply and the method for CPU frequency modulation mechanism protection system specifically.
Background technology
Current server product is facing under the short-term high load condition, usually uses the processing of finishing the work of CPU overlockin (turbo boost) in the short time.Thereby buy the spending that high frequency is processed for the user saves, realize better product cost performance.But the overlockin of short-term CPU also can cause the increase of system power dissipation, and in some abominable situation, the too high overclocking work of CPU may cause the Power supply overcurrent protection and cause the whole system power down, user's application interruption.The just appearance of this situation greatly reduces the reliability of server, and the user uses safe not.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and the method for a kind of current detecting by power supply and CPU frequency modulation mechanism protection system is provided.
Technical scheme of the present invention realizes in the following manner; the method of this a kind of server power supply protection system; comprise server power supply, CPU; current detection circuit and Rapid Alarm circuit are set in server power supply inside; be provided with buffer capacitor between described server power supply and the CPU, its concrete system protection step is:
1) current threshold of power supply is set by the power consumption number of server system maximum;
2) power supply internal current testing circuit detects current current value in real time;
When 3) current current value is less than current threshold, the power supply normal operation;
4) current current value greater than or during near current threshold, the Rapid Alarm circuit is triggered, this Rapid Alarm circuit stops overclocking work, reduces current demand to CPU by the voltage signal trigger notice, CPU adjusts the work at present frequency according to this alerting signal, simultaneous buffering electric capacity is triggered and starts, and avoids current fluctuation to affect system.
In technique scheme; current detection circuit is realized the overload detection to power supply, and the Rapid Alarm circuit directly is triggered to CPU by voltage signal, and warning CPU adjusts the work at present frequency; thereby in time reduce CPU to the demand of power consumption, realize the protection to server power supply
The size of described buffer capacitor is calculated C=P/V1 * [T/ (V1-V2)] by formula; P in the above-mentioned formula is the difference that power supply estimates to occur maximum power dissipation and rated disspation; V1 is supply voltage, the magnitude of voltage that V2 causes when being current fluctuation, and T is the buffer protection time of design.
Buffer protection function when the buffer capacitor in the technique scheme occurs changing rapidly as electric current; the system that can realize also can not change excessive and causes the machine problem of delaying because of the fluctuation of electric current after frequency reducing at CPU, strengthens the reliability of whole server power supply protection system.
The described buffer protection time is 100 μ m.
The beneficial effect that the present invention compared with prior art produces is:
The method of a kind of server power supply protection system of the present invention judges in advance that by current detecting and CPU frequency modulation mechanism to power supply overload fault appears in the prevention power supply, and the reliability of Effective Raise server ensures user's application safety.
