Embodiment
As shown in Figure 1, be the block scheme of realizing computer temperature control device of the present invention, in order to reach the purpose of temperature control, include in computer-internal: control device 1 is used to control cpu fan and power supply fan rotating speed; Cpu temperature reading device 2; Cpu fan 3; Cpu fan revolution speed control device 4; Computer power supply 5 wherein includes in computer power supply 5 inside: computer power supply fan 51, internal electric source fan rotation speed control apparatus 52, selector switch 53, power supply thermal detector 54; External power source fan rotation speed control apparatus 6.
Above-mentioned control device 1 can utilize BIOS on the computer motherboard, that store the program of control cpu fan and power supply fan rotating speed to realize, temperature T j by periodic monitor CPU, realize control, reach in the purpose that guarantees minimum noise under the CPU working temperature normal condition to cpu fan 3 and power supply fan 51.As shown in Figure 1, cpu temperature reading device 2 periodically reads the temperature of CPU and offers BIOS 1, the cpu temperature that BIOS 1 obtains according to monitoring and correspondingly export two temperature signals and offer cpu fan revolution speed control device 4 and external power source fan rotation speed control apparatus 6 respectively, wherein cpu fan revolution speed control device 4 is according to exporting a voltage-controlled signal V from the signal of BIOS 1 CpufanControlling cpu fan 3 rotates with corresponding rotating speeds; And external power source fan rotation speed control apparatus 6 is exported an external power source fan control signal V according to the signal of BIOS 1 output Pwfan, and offer the selector switch 53 of computer power supply 5 inside; This selector switch 53 also receives the internal electric source rotation speed of the fan control signal V that is exported according to the power supply actual temperature of power supply thermal detector 54 measurements by internal electric source fan rotation speed control apparatus 52 Pw, and output speed control signal V PwfanAnd V PwMiddle magnitude of voltage the greater V FanGive power supply fan 51, the rotating speed of control fan 51.
Describe the relevant temperature control scheme of the present invention that realizes below in detail:
1. make cpu temperature reading device 2 regularly read cpu temperature Tj, the time interval can be set at Tm.Because temperature variation is relatively slow, second level that is set at of Tm gets final product.Implement circuit diagram for one that figure 6 illustrates cpu temperature reading device 2 that the present invention adopts, owing to realize that in this technical field the circuit that temperature reads is well-known technology, therefore omit explanation this figure at this;
2. set BIOS 1 gives cpu fan 3 by cpu fan revolution speed control device 4 control voltage V CpufanBe many grades of controls, corresponding different Tj, BIOS 1 provide the cpu fan control voltage V of corresponding class Cpufan, V wherein CpufanSpan be 0-V Cpufanmax, V Cpufanmax, be the maximum rated control voltage of cpu fan 3.In the present embodiment, with the control voltage of cpu fan 3 be divided into two grades (8V, 12V).Because CPU is bigger in the dynamic change of when operation heating, and CPU is responsive to ratio of specific heat, so be dangerous with cpu fan 3 stalls.Be set at minimum 8V and can guarantee CPU radiating requirements at low temperatures, guaranteed to a certain extent that again the dynamic temperature rise of CPU is unlikely too high.The second gear control of cpu fan 3 is simple and reliable, can not produce too much influence to system.
3. set BIOS 1 gives power supply fan 51 by external power source fan rotation speed control apparatus 6 control voltage V PwfanBe many grades of controls, corresponding different Tj, BIOS 1 provides the control voltage V of different class Pwfan, and V PwfanSpan be 0-V Pwfanmax, V PwfanmaxBe the maximum rated control voltage of power supply fan 51.In the present embodiment, the control voltage of setting power supply fan 51 be third gear control (0V, 8V, 12V).The stepping control ratio curve controlled of power supply fan 51 is simple, and is reliable.Because the effect that power supply fan 51 plays again to system and power supply heat sinking simultaneously is rational so participate in controlling the power supply fan rotating speed by system.Because the temperature tolerance level of power supply body is better, and system's temperature rise is slower, for hour magnitude, so 0 rotating speed of power supply fan 51 is feasible, also be reliable, unexpected temperature rise can not take place and burn other devices in the system.The design of 8V gear also is reasonably, when system temperature raise but and unlikely when too high, fan 51 opened and under 8V the slow-speed of revolution can solve heat dissipation problem effectively, be unlikely again simultaneously and bring too big noise to increase.
4. define system state (called after S) has following several situation (power supply fan, cpu fan): (0V, 8V), (8V, 8V), (8V, 12V), (12V, 12V), can be respectively with state called after KS0, KS1, KS2, KS3.
Definition temperature thresholding is as follows: Ts1, Ts2, Ts3, three switching temperature of representative system state respectively.
The system temperature State Control is referring to Fig. 2, Fig. 2 is the temperature control constitutional diagram of realization system, state of a control when wherein last figure is the temperature rising, and the state of a control of figure below when representing that temperature descends, for preventing that very fast vibration from appearring in system temperature, in decline curve the temperature controlling Design is become Schmidt's curve, definition Schmidt parameter is Tt.
Fig. 5 is the process flow diagram of realization system temperature control state.Referring to Fig. 5, at first, at step S1, the temperature control state that BIOS 1 reading system is current also is assumed to KSn, obtain the temperature T j of CPU at step S2 BIOS 1, and the threshold temperature Tsn+1 of next state KSn+1 compares in step S3 and temperature control state, if temperature T j has surpassed Tsn+1, then enters next state KSn+1 at step S4 system temperature control state; Otherwise control program turns back to step S2, continues periodically to read cpu temperature Tj.Below be the logical program of realizing the control curve:
If (S==KS0 ﹠amp; ﹠amp; The S=KS1 of Tj>Ts1);
If (S==KS1 ﹠amp; ﹠amp; The S=KS2 of Tj>Ts2);
If (S==KS2 ﹠amp; ﹠amp; The S=KS3 of Tj>Ts3);
The control and the propradation of system temperature decline state are similar substantially, and difference is, when the temperature control state is Tsn+1-Tt from the threshold temperature that high temperature condition KSn+1 enters into low temperature state KSn, rather than Tsn+1.Below be the logical program of realizing this control curve:
If (S==KS3 ﹠amp; ﹠amp; The S=KS2 of Tj<TS3-Tt);
If (S==KS2 ﹠amp; ﹠amp; The S=KS1 of Tj<TS2-Tt);
If (S==KS1 ﹠amp; ﹠amp; The S=KS0 of Tj<TS1-Tt);
Be the system's temperature control scheme in BIOS 1 above.The voltage V of power supply fan 51 rotating speeds defined above PwfanBe system's output voltage of a relative ideal, not power supply fan 51 rotating speeds really.The rotating speed of real power supply fan 51 is controlled jointly by the BIOS 1 in power supply thermal detector in the power supply body 54 and the mainboard.The design of power supply controlling schemes is as follows:
Adjust power supply temperature inside control curve and change stepping control into, be defined as equally: 0V, 8V, 12V.This rotating speed control is by power supply thermal detector 54 monitoring power supply temperature inside Tp, and then control power supply fan 51 rotating speeds.Defining two temperature thresholdings is Tp1, Tp2, and the inner temperature control curve of this power supply own is seen Fig. 3.In Fig. 3, V PwBe the ideal control voltage of power supply body to power supply fan 51, actual power supply fan voltage is by the V of power supply body PwControl voltage V with the power supply fan that BIOS provides PwfanCommon control, its steering logic is as follows:
V fan=Max(V pw,V pwfan)
Fig. 4 shows the circuit of realizing this logic.As can be seen, the clamping circuit that is made of two diodes is with V from this circuit diagram PwAnd V PwfanA middle bigger V of magnitude of voltage FanExport to power supply fan.
Above power supply fan 51 controlling schemes had both guaranteed the demand of system radiating, had also guaranteed the demand of power supply body self-radiating, all were safe concerning power supply and system, can not bring other negative influences.
The realization principle and the mode of system's temperature control strategy have been described in detail in detail above, and have proposed several formula and control curve.Following surface analysis is choosing method and the initial setting value and the meaning thereof of each parameter once.
1. sampling time Tm's determines.
Sampling time has determined the response susceptibility of system to heat radiation, also can influence the minimum switching time of each fan in the system.Because temperature variation is a process more slowly, cpu fan again can stall simultaneously, and the minimum heat of CPU is guaranteed, thus can design the sampling time for second grade.Sampling period Tm that can definition of T j is 8 seconds.This sampling period intercepts and captures SMI by BIOS 1 and interrupts obtaining, owing to only need read Tj simply and carry out several outputs that relatively reach among the BIOS 1, can not influence the work that clock interrupts, and also can not influence the accuracy of system clock.
2.Ts1, Ts2, Ts3 determines
Determining of these three parameters is very important, and it has determined the different temperatures scope of several noise states of system.Wherein, Ts1 be system (0V, 8V) to (8V, the 8V) switching temperature of state, its implication are that cpu fan 3 is low changes, power supply fan 51 to low switching temperature of changeing, also is the maximum permissible temperature under the minimum system radiating state from stall.Ts2 be system (8V, 8V) to (8V, the 12V) switching temperature of state, its implication are that power supply fan 51 is low changes, cpu fan 3 forwards high switching temperature of changeing to from low.Ts3 be system (8V, 12V) to (12V, the 12V) switching temperature of state, its implication are that cpu fan 3 is high changes, power supply fan 51 forwards high switching temperature of changeing to from low, also is the minimum temperature of the maximum radiating state of system start-up.Following table is the temperature parameter of the P4 of Intel,
Cpu type ??Tc
??Willamette-478?1.3G ??70
??Willamette-478?1.4G ??71
??Willamette-478?1.5G ??73
??Willamette-478?1.6G ??74

??Northwood-478?2.4G ??66
??Northwood-478 ??70
Can be clear and definite find out, the P4 temperature permissible value Tc of Willamette is minimum to be 70 degree, and Northwood has been owing to changed manufacturing process, temperature value Tc has dropped to 63 degree, thus with the very big difference of parameter existence of Willamette.Like this, can be clear and definite, system's temperature control will be adopted different setting values to Willamette with Northwood.For Willamette, Tc is minimum to be 70 degree, and the Tj of actual measurement can be than about high 1 degree of Tc, so the Tj extreme value is 71 degree.The test error of considering Tj is ± 3 degree, and considers security and stay bigger allowance, can initial setting Ts3 be 60 degree.Like this, make the Tj of CPU when 60 spend, just start maximum radiating mode, guaranteed the heat radiation of system.
Ts2 has represented power supply fan 51 low commentaries on classics, and cpu fan 3 is from the low switching temperature that forwards high commentaries on classics to, and it is representing the full temperature of changeing of cpu fan 3 needs when there is the short-term temperature rise in CPU, sets with reference to the temperature of Ts3, and can set Ts2 is 50 degree.
Ts1 has represented the temperature threshold limit value under the minimum radiating state of system, considers that system is under the applied environment of Desktop at 25 degree normal temperature, and the Tj of this moment should be less than Ts1.Consider the minimum thermal value of the internal temperature rise and the CPU of system, can set Ts1 is 40 degree.
3.Tt determine
Tt is the Schmidt's parameter that prevents that the very fast vibration of system temperature appearance from designing, and the temperature that promptly rises and descend is difference relatively.Can be set at Tt=3.
4.Tp1, the setting of Tp2
Because Tp1, Tp2 is the power supply temperature inside, and relevant in the position of power supply 5 inside with its monitoring point, different power supplys have difference.So the parameter system of can't help determines, but is decided in its sole discretion by power supply producer.The principle of decision is that Tp2 is fan minimum the open temperature of the temperature that prevents power supply body 5 when too high, and Tp1 be the maximum temperature permissible value that the no fan of power supply body 5 under 25 degree normal temperature dispels the heat.As air themperature in the temperature sensor reflection power supply of power supply, can advise the Tp2=55 degree, the Tp1=40 degree.
Top initial setting the initial value of Several Parameters, concrete numerical value also needs the test decision.Be the principle of test and the effect that will reach below.
1. system is spent under the normal temperature 25, the desktop state of Win98, and when no application program was moved, system should be in the KS0 state.
2. system is under 25 degree normal temperature, and system moves the Demo of 3DMark2000 under Win98, and system should be in KS1 or KS0 state.
3. system is under 35 degree high temperature, and system moves the Demo of 3DMark2000 under Win98, and system should be in KS2 or KS1 state.
4. system moves MaxPower 75% under 35 degree high temperature,, system should be in the KS3 state.
In each different system, need test according to above principle, and in conjunction with the setting principle of initial value, decision Ts1, Ts2, the last numerical value of Ts3.
The option of system's temperature control is reserved in test for convenience in need the Setup in BIOS, comprises Enable/Disable (startups/shutoffs), and Ts1 sets, Ts2 setting, Ts3 setting.Ts1, Ts2, the setting range of Ts3 are 30 degree to 65 degree, and thermograde is 2 degree.After system evaluation and test is finished, before sales computer, need mask Ts1, Ts2, the Enable/Disable option of system's temperature control is only stayed in the setting of Ts3.
Narrated the implementation method of system's temperature control above, we can estimate its noise control effect very simply.The fully loaded noise of supposing system when the temperature control of no system is 35dB, and promptly KS3 is 35dB.Can test out the level of noise of other each states at an easy rate.Estimate earlier that because the KS2 state is that power supply fan is become low the commentaries on classics, can be estimated as KS2=32dB, other in like manner can be estimated as KS1=30dB, KS0=27dB.
If above-mentioned test request can satisfy, just can see that system noise will be controlled at about 30dB when moving big game softwares such as 3D at normal temperatures, effect is very obvious.
Analyze again below and carry out several problems that system's temperature control may run into.
1. the cooperation of type
System's temperature control scheme is tackled each type customized solution in theory, in fact just to Ts1, and Ts2, the selection of Ts3 need reset.For the different mainboards in the same type, though BIOS has difference, the temperature control parameter should be identical.
2.CPU upgrade problem
For Northwood and the big like this CPU change action of Willamette, system's temperature control is necessarily need reset parameter.But, can adopt the method for stepping for the conventional CPU upgrading of Willamette series.All adopt heat radiator and the parameter of 1.8G such as 1.5G to 1.8G, and 1.9G and 2.0G adopt heat radiator and the parameter of 2G.
3. heat radiator is selected problem
For the selection of the different heat radiator of same frequency CPU, problem is also little.As long as heat radiator can meet the requirement of heat radiation, different heat radiator can bring different noise result at most, and this is the same with not adopting system's temperature control.But be noted that, need rotating stability and the heat radiation noise result thereof of fan under the 8V state on the test heat radiator.As long as passed through the stability test of 8V, this heat radiator promptly can be applicable in the system.
More than at specific embodiment the present invention has been described, the people in the present technique field can expect, can also make other variation, modification in the scope that does not break away from claim of the present invention and contained, and all within the scope of the invention.For example, in the present embodiment, the control of cpu fan 3 adopted (8V, second gear control 12V), but can expect also can be adopted third gear or other Control of Voltage of multiscale more, to realize better heat radiating and mute effect.Equally also can adopt other Control of Voltage, and these change all in protection scope of the present invention greater or less than third gear for power supply fan.
