Abstract
The invention discloses a kind of methods for preventing BMC from hanging after death fan stalling, comprising the following steps: hardware control unit obtains BMC heartbeat signal；If hardware control unit does not obtain BMC heartbeat signal, hardware control unit controls fan and carries out full speed rotation.The method disclosed by the invention for preventing BMC from hanging after death fan stalling, by increasing hardware control circuit, and draws the heartbeat signal of BMC to hardware control module, to detect the state whether BMC goes back Active, when BMC is hung after death, carry out fan control is taken over by hardware control circuit, ensures heat dissipation.
Description
Technical field
The present invention relates to technical field of memory more particularly to a kind of methods for preventing BMC from hanging after death fan stalling.
Background technique
In currently stored field, for storage product, heat dissipation is critically important part.Currently, the governor of fan
System, key step have: 1.BMC obtains the temperature in cabinet by reading the numerical value of Sensor on plate；2.BMC passes through acquisition
Temperature calculates corresponding PWM to regulate and control the revolving speed of fan, achievees the purpose that system radiating；3.BMC controls wind by GPIO
Indicator light is fanned, whether instruction fan normally rotates.
But this mechanism is entirely the code realization control management by BMC, once the BMC occurred hangs dead situation,
The revolving speed of fan be it is uncontrolled cut uncertain, status lamp also will appear the instruction of mistake, this just has system radiating to be unsatisfactory for, and is
The risk that system is broken down.
Based on the above issues, therefore, to those skilled in the art, prevent from BMC from hanging after death fan to stall, be to need
The technical issues of solution.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of sides for preventing BMC from hanging after death fan stalling
Method by increasing hardware control circuit, and draws the heartbeat signal of BMC to hardware control module, whether also to detect BMC
The state of Active takes over carry out fan control by hardware control circuit, ensures heat dissipation when BMC is hung after death.
A kind of method for preventing BMC from hanging after death fan stalling proposed by the present invention, comprising the following steps:
Hardware control unit obtains BMC heartbeat signal；
If hardware control unit does not obtain BMC heartbeat signal, hardware control unit controls fan and carries out full speed rotation.
Preferably, it is further comprising the steps of: if hardware control unit does not obtain BMC heartbeat signal, hardware control unit
Fan indicator instruction BMC is controlled to hang extremely.
Preferably, it is further comprising the steps of: if hardware control unit does not obtain BMC heartbeat signal, hardware control unit
It controls fan indicator instruction fan and carries out full speed rotation.
Preferably, further comprising the steps of:
BMC obtains the temperature value in cabinet by Sensor；
BMC calculates corresponding pwm signal according to the temperature value in acquired cabinet to regulate and control the revolving speed of fan.
Preferably, it further comprises the steps of: BMC and fan indicator instruction fan normal rotation is controlled by GPIO.
Preferably, pwm signal is transferred to hardware control unit by BMC, and regulates and controls fan by hardware control unit
Revolving speed.
A kind of method for preventing BMC from hanging after death fan stalling provided in the present invention, by increasing hardware control circuit, and
The heartbeat signal of BMC is drawn to hardware control module, to detect the state whether BMC goes back Active.Extremely will if BMC is not hung
Normal to issue heartbeat signal, the pwm signal that MBC is issued is only to pass through hardware control circuit to be given to fan again, controls source
It is still BMC.If MBC is hung in the dust, hardware module would not receive the heartbeat signal of BMC sending again.The PWM of rotation speed of the fan believes
It number is taken over by hardware control module, becomes stable high level, be equivalent to the pwm signal that duty ratio is 100%, fan turns at full speed
To guarantee system radiating.The signal of indicator light is issued, by hardware control module simultaneously come when indicating fan full speed rotation at this time
Because caused by BMC is hung extremely, rather than according to the regulation of the temperature of reading.
Detailed description of the invention
Fig. 1 is a kind of flow chart of method for preventing BMC from hanging after death fan stalling proposed by the present invention.
Specific embodiment
As shown in FIG. 1, FIG. 1 is a kind of flow charts for the method for preventing BMC from hanging after death fan stalling proposed by the present invention.
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
A method of it prevents BMC from hanging after death fan and stalls, comprising the following steps:
S1: hardware control unit obtains BMC heartbeat signal；
S2: if hardware control unit obtains BMC heartbeat signal, step S3 is gone to, if hardware control unit does not obtain BMC
Heartbeat signal then goes to step S6；
S3:BMC obtains the temperature value in cabinet by Sensor；
S4:BMC calculates corresponding pwm signal according to the temperature value in acquired cabinet, and pwm signal is transferred to by BMC
Hardware control unit, and regulate and control by hardware control unit the revolving speed of fan；
S5:BMC controls fan indicator by GPIO and indicates fan normal rotation；
S6: hardware control unit controls fan indicator instruction fan and carries out full speed rotation；
S7: hardware control unit controls fan indicator instruction BMC and hangs extremely.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
