Believe interface, plant maintenance personnel can plant maintenance end facilities for observation in real time health status, go out in equipment working state
Failure cause quickly is positioned when now abnormal, is fixed a breakdown, the good operation conditions of maintained equipment.Attendant can also pass through
BMC sends switching on and shutting down and instruction of restarting, long-range controlling equipment to equipment.BMC presence greatly facilitates plant maintenance people
Management work of the member to hardware device.
CPU overheats are the problem of computer equipment can run into unavoidably in the course of the work, cause the reason for CPU is overheated to have very
It is many, such as excess load works long hours, supply voltage is unstable or cooling measure is bad etc..Slight CPU heatings will not be to CPU
Performance and mainboard etc. cause the influence of especially severe, however, when cpu temperature exceedes certain limit, such as it is serious more than CPU factories
As defined in family during CPU normal range of operation, CPU performance will be reduced, if working long hours under this superheat state, not only
The service lifes of CPU in itself can shorten, and equipment can be caused to delay suddenly machine, in addition cause that whole mainboard damages it is serious after
Really.General CPU carries safeguard measure in itself, when CPU is overheated, and the frequency of CPU work is typically reduced by way of frequency reducing, so
And, many times, even if frequency reducing can not alleviate the crisis situation that CPU persistently overheats, it is necessary to which other means auxiliary is solved the problems, such as.
The content of the invention
In view of the shortcomings of the prior art, the present invention proposes a kind of CPU method for excessive heating protection based on BMC.It is of the invention effective
Ground reduce CPU due to work long hours or unknown cause caused by overheat the infringement that is caused to itself and thus may trigger
Remaining risk.

According to currently preferred, the temperature sensor chip is W83795 chips, and the W83795 chips pass through I2C
Bus is connected with the BMC chip, and the other end of the W83795 chips is connected with being close to the thermistor of the CPU.
According to currently preferred, the model AST2400 of the BMC chip.
According to currently preferred, power circuit hair of the BMC chip according to the temperature change of the CPU to server
Order, including：Periodically monitoring cpu temperature, is compared and is counted with the temperature threshold set by judging cpu temperature
Number：When the temperature continuous several times monitored exceed temperature threshold when, and number of times exceed set counter threshold when, BMC chip
Shutdown command is sent to the corresponding mainboards of CPU and relative recording is left in daily record.
According to currently preferred, power circuit hair of the BMC chip according to the temperature change of the CPU to server
That orders comprises the following steps that：
1) temperature threshold is set：Identify the cpu temperature upper limit；Counter threshold is set：Identify the meter of CPU persistent fever times
The number upper limit；By counter O reset；
2) temperature sensor chip periodically gathers cpu temperature, by the cpu temperature collected and the temperature threshold
Value compares：
If 2-1) cpu temperature exceedes the cpu temperature upper limit, counter adds 1；Then judge to count in counter and whether reach
The count upper-limit of setting：If reaching count upper-limit, shutdown command is sent and in day to the corresponding mainboards of CPU by BMC chip
Relative recording is left in will；If being not reaching to count upper-limit, continue periodically collection cpu temperature, repeat step 1) -2)；
If 2-2) cpu temperature does not reach the cpu temperature upper limit, judge to count in counter whether be on the occasion of：If on the occasion of,
Then counter subtracts 1, continues periodically collection cpu temperature, repeat step 1) -2).
The technical advantages of the present invention are that：
The present invention proposes a kind of CPU method for excessive heating protection based on BMC, significantly reduces CPU due to working long hours
Or the infringement caused to itself of overheat caused by unknown cause and remaining risk that thus may trigger.Present invention design：When
CPU cross thermal endurance it is long when, automatic shutdown simultaneously records dependent event, wherein, the lasting overheat time of the CPU is logical
Cross what a counter was weighed, it is lasting overheat or intermittence that can distinguish CPU by the simple plus-minus operation of counter
Heating, to avoid unnecessary power-off operation.
