Description

The system and method for instant control notebook computer central processor temperature

The present invention relates to a kind of system and method for temperature of instant control notebook computer central processing unit.

Along with high-speedization and the multifunction of computer cpu (CPU), its heat radiation power constantly increases along with the lifting of frequency of operation, and therefore the heat dissipation problem of computer is healed and become serious, also influences the working stability degree of computer greatly.Now, notebook computer is more and more universal, but overheated and cause crashing by the what central processing unit, and the communicating interrupt, the vital document data that are therefore caused are lost even incident such as indivedual hardware damage happens occasionally.So the temperature that can control the notebook computer central processing unit immediately just becomes very important.

The control of notebook computer central processor temperature, generally be to decide by basic input/output (BIOS), be difficult to revise at any time, therefore some have the use of specific demand to what, abominable as: machine run environment, have data on specific (special) requirements or the machine very important and mechanical stability against short circuit is required very strict or the like, just very inconvenient to central processor temperature.Most at present producers does not dispose the software of corresponding monitoring central processor temperature, promptly can not detect the temperature of central processing unit, can not in time take to control the measure of temperature.

In view of this, the object of the present invention is to provide a kind of system and method for temperature of instant control notebook computer central processing unit.The present invention is set the warning temperature value of central processing unit by the user, also can utilize the preset value of default, and when the central processing unit continuous firing, promptly constantly detect its temperature, when the temperature one of central microprocessor surpasses the warning temperature, take corresponding cooling measure to regulate temperature immediately, so can realize controlling immediately the notebook computer central processor temperature.

According to the present invention, a kind of system of temperature of instant control notebook computer central processing unit, wherein, this notebook computer has a drive fan module and a fan, this system comprises: (1) one setting module, guard against temperature value by this setting module to set one; (2) one detection modules immediately detecting central processor temperature at that time, and are obtained a temperature value at that time of this central processing unit by this detection module; And (3) one temperature-regulating modules, so as to obtain in this detection module this at that time temperature value judge, calculate the rotating speed that this fan should reach to call this drive fan module, restart this fan.

For allow above-mentioned and other purposes of the present invention, feature, and advantage can become apparent, cited below particularlyly go out preferred embodiment, and cooperate appended accompanying drawing, be described in detail below:

Fig. 1 is the control flow chart of display setting module.

Fig. 2 is the control flow chart that shows detection module.

Fig. 3 is the control flow chart that shows temperature-regulating module.

The present invention will cooperate appended accompanying drawing to elaborate, the invention provides a kind of system of temperature of instant control notebook computer central processing unit, wherein, this notebook computer has a drive fan module and a fan, this system comprises: (1) one setting module, guard against temperature value by this setting module to set one; (2) one detection modules immediately detecting central processor temperature at that time, and are obtained a temperature value at that time of this central processing unit by this detection module; And (3) one temperature-regulating modules, so as to obtain in this detection module this at that time temperature value judge, calculate the rotating speed that this fan should reach to call this drive fan module, restart this fan.

The detailed description of each module:

(1) setting module: see also Fig. 1, this module at first reads user's setting value, if the user does not set, then adopts the preset value (as 70 ℃) of default, and supports that the user revises the warning temperature value at any time.Its flow process is as follows:

(101) beginning; The default warning temperature value of a given central processor temperature when (102) moving for the first time; (103) whether the user will change the warning temperature value; If then (104) change warning temperature value is the value that the user imported; If not, then finish (105).

(2) detection module: see also Fig. 2, when carrying out temperature control, need immediately detect current central processor temperature, only need the SMC951 wafer on motherboard to send the instruction of getting central processor temperature during actual detected, the corresponding working storage of SMC951 wafer will return central processor temperature value at that time.Its flow process is as follows:

(201) beginning; (202) initialization SMC951 wafer; (203) send the order that detects central processor temperature to the SMC951 wafer; (204) read the working storage of SMC951 wafer to obtain central processor temperature value at that time; (205) judge whether the central processor temperature value surpassed the warning temperature value at that time; If then (206) call this temperature-regulating module; If not, then finish (207).

(3) temperature-regulating module: see also Fig. 3, judge,, then call the drive fan module immediately, calculate the rotating speed that fan should reach, send the order of drive fan again to SMC951 if surpass the warning temperature value for the rreturn value that in detection module, obtains.Its flow process is as follows:

(301) beginning; (302) call the drive fan module and calculate the rotation speed n that fan should reach; (303) this SMC951 wafer of initialization; (304) send the order of drive fan and turn round to SMC951 with rotation speed n; (305) finish.

This system is standby carrying out Hou, timing response interrupts, immediately carry out thermometric, in case find that temperature is too high, lower the temperature with regard to starting fan automatically, if temperature was higher above the warning temperature value at that time, corresponding rotation speed of the fan is also just fast, so just can guarantee immediately that central processor temperature can be under the warning temperature value that the user sets, and support the user to revise the size of this value at any time, to satisfy different users's specific (special) requirements.

Advantage of the present invention: the warning temperature value of (1) central processing unit can be set by the user, and can revise at any time, the user that this just can make things convenient for some that specific demand is arranged is abominable as: machine run environment, have data on specific (special) requirements or the machine very important and mechanical stability against short circuit is required very strict or the like to central processor temperature.(2) system and method provided by the present invention allows the user as long as the algorithm that calculates rotation speed of the fan is changed a little, just can improve temperature controlled precision as required, makes monitoring intelligent more.(3) this method both can be used as a module of user's program, was embedded among user's program, again can be separately as a program write memory, carry out convenient, flexibly, be easy to upgrade.(4) can control central processor temperature immediately, effectively prevent to cause mechanical disorder, prevent trouble before it happens because of central processor temperature is too high.

Though the present invention is disclosed with preferred embodiment; so be not in order to limit the present invention; anyly be familiar with this skill person; without departing from the spirit and scope of the present invention; when can doing to change and retouching, so protection scope of the present invention protection domain that should look accompanying claim defines and is as the criterion.
