For example work as at time ta, when any temperature-sensitive sticker 21,22,23 detected temperature T that system is heated and arrives Ta, controller 20 was by the timing of built-in timing module 201, according to above-mentioned formula calculating TS (T, Δ t) value is subjected to calorific value TS with what obtain a system.Ai=0 in for example above-mentioned formula; Bi=1; During Δ t=10, be with 10 seconds be the time interval, be subjected to calorific value TS to equal Ta and add from the time to be that ta is counted the per 10 seconds temperature values at interval the time in regular turn; Perhaps when a certain temperature range, make temperature value add certain weighted value ai or be multiplied by various mathematical operations such as certain weighted value bi.Arrive tb when the time, when the formula TS value of supposing to be heated arrives the different values of imposing a condition, the various as previously mentioned corresponding different heat radiation protection control models of 20 execution of controller.Ai=1 in the and for example above-mentioned formula; Bi=0; During Δ t=10, be with 10 seconds be the time interval, calculating from the time is whether ta counts per 10 seconds temperature T at interval more than or equal to Tn, and the number of times of T 〉=Tn is added stack up is used as the TS value;
6. produce the TS value with following formula:
, wherein () is a Gaussian function; Ai, bi are arbitrary real number, and i is 0 and in regular turn positive integer; Tn is at least one desired temperature; Illustrated person among the explanation of relevant ai, bi, ts, Δ t such as above-mentioned the 5th.Utilize this formula to calculate the TS value, do not need to judge whether earlier T 〉=Tn, and be direct calculating TS value, this be because usually the working temperature of system on the occasion of, and before no show still 2, Ti (ts+i* Δ t) promptly may cause system overheat to stop normal operation to (Ti (ts+i* Δ t))/value of Tn greater than Tb usually.Be with, when the value of (Ti (ts+i* Δ t))/Tn less than 1 and more than or equal to 0 the time, ((Ti (ts+i* Δ t))/Tn)=0 is so utilize the TS (T, Δ t)=0 of above-mentioned formula gained; And the value of working as (Ti (ts+i* Δ t))/Tn is less than 2 and more than or equal to 1 the time, and ((Ti (ts+i* Δ t))/Tn)=1 so utilize the TS (T, Δ t) of above-mentioned formula gained identical with above-mentioned the 5th formula, is:
See also shown in Fig. 2,4.The embodiment of the method that control system of the present invention is worked under proper temperature comprises the steps:
(51) controller 20 continues the system that detects by at least one temperature-sensitive sticker 21,22,23, continues to obtain at least one temperature value T, the temperature value person of for example above-mentioned T1 to T10; Temperature value T can also be the arithmetic mean value of sensor 21,22,23 detected several temperature values;
(52) controller 20 makes this temperature value T and predefined at least one desired temperature Tn, and the temperature value of for example above-mentioned T1 to T10 is compared, if T＜Tn then makes controller 20 continue to make T to compare with Tn; If T 〉=Tn then enters step (53);
What (53) make controller 20 computing systems is subjected to calorific value TS, is subjected to calorific value TS relevant with the heating temperature and the heated time of system;
(54) make controller 20 with system be subjected to calorific value TS and at least one setting value PL, the value of for example above-mentioned PL1 to PL10 is compared, if TS＜PL then makes controller 20 continue to make TS to compare with PL; If TS 〉=PL then enters step (55);
(55) controller 20 is carried out and the corresponding control model of setting value PL, for example above-mentioned control model A to J, output control signal CS1;
(56) controller 20 makes this temperature value T and predefined at least one desired temperature Tn, the temperature value of for example above-mentioned T1 to T10 is compared, if T 〉=Tn then makes controller 20 continue to make this temperature value system wherein to can be notebook computer system or desktop computer system; And be subjected to calorific value TS, be to produce the survivor with aforementioned variety of way; But, because of not needing to judge whether earlier T 〉=Tn, and be direct calculating TS value, so can not need step (52) if produce when being subjected to calorific value TS in above-mentioned the 6th kind of mode.
Control signal CS1 in the step (55) is the control signal to central processing unit 24, fan 25 or power circuit 26 outputs, makes fan 25 improve rotating speed; Make central processing unit 24 reduce usefulness; Or make power circuit 26 shutdown system power supplys, to carry out various protections.Control signal CS2 in the step (57) is the control signal to central processing unit 24, fan 25 or power circuit 26 outputs, makes fan 25 reduce rotating speed; Make central processing unit 24 increase usefulness; Or make the control signal of power circuit 26 open system power supplys etc.
See also shown in Figure 5.Implement second embodiment of the device of the inventive method, comprise that a controller 30 is electrically connected at least one temperature- sensitive sticker 31,32,33 and central processing unit 34, fan 35, power circuit 36, timer 37 respectively; Wherein timer 37 is to be independent of outside the controller 30.
