The present invention is the relation between limiting controling unit 110 and the mnemon 170 not.In a possibility embodiment, mnemon 170 is integrated into an intergrated circuit with control unit 110.In another possibility embodiment, mnemon 170 is independent of outside the control unit 110.
In the present embodiment, control unit 110 can be carried out a specific action according to the stored data of mnemon 170.The present invention does not limit the kind of specific action.Below enumerate three kinds of possible specific actions, but be not in order to restriction the present invention.
In a possibility embodiment, this specific action can be and drives loudspeaker 191, and loudspeaker 191 are sounded.The sound that the user can be sent according to loudspeaker 191 is learnt the operating condition of present fan 150.For example, as rotating speed S
SP1With S
SP2Between gap during less than a predefined value, expression fan 150 is unusual.Therefore, control unit 110 just drives loudspeaker 191, in order to notify the user.
In another possibility embodiment, this specific action is to adjust control signal S
C2, in order to change the rotating speed of fan 150.For example, when unusual (wearing out) takes place in fan 150, even if power-supply unit 130 produces fixing operating voltage V
OPThe time, the rotating speed of fan 150 may reduce.
In order to keep the usefulness of fan 150, the rotating speed S that control unit 110 can be returned according to fan 150
SP2, suitably adjust control signal S
C2, make power-supply unit 130 adjust operating voltage V
OPIn a possibility embodiment, power-supply unit 130 increases operating voltage V
OP, in order to keep the rotating speed of fan 150.
In addition, in order to prolong the life-span of fan 150, when the rotating speed of fan 150 when aging and slack-off, control unit 110 can suitably be adjusted control signal S
C2In a possibility embodiment, power-supply unit 130 is according to control signal S
C2, reduce operating voltage V
OPThough the rotating speed of fan 150 may be slack-off, can prolong the life-span of fan 150.
In other possibility embodiment, control unit 110 performed specific actions can be, with rotating speed S
SP1And S
SP2Between relation be presented in display unit 193.In addition, when starting radiation system 100, control unit 110 just produces control signal S earlier at every turn
C1, (be rotating speed S in order to the minimum speed of learning fan 150
SP1), then, control unit 110 produces control signal S again
C2, in order to learn the rotating speed S of fan 150
SP2Therefore, the picture that the user can be shown according to display unit 193 is learnt the state of fan 150.
Fig. 2 is the stored rotating speed S of mnemon 170
SP2Relation curve.Suppose that radiation system writes down the rotating speed of fan 150 100 every months.Under perfect condition, when deterioration phenomenon took place fan 150, the minimum speed of fan 150 remained unchanged.Under actual state, even if the minimum speed of fan 150 changes, because the degree that changes is very little, so can ignore.
As shown in the figure, when the time that fan 150 uses was longer, its rotating speed may be slack-off gradually.As shown in Figure 2, the change curve of rotation speed of the fan has linear performance, so can infer, probably more how long, it (is S that the rotating speed of fan 150 just can reach minimum speed
SP1).In the present embodiment, according to the 1st ~ 4 month speed curves, can infer, in the time of 5th month, fan 150 rotating speeds just can reach minimum speed greatly.Therefore, if the result after will inferring informs the user, just can allow the user make strick precaution (as more renewing fan) ahead of time.
In other may embodiment, control unit 110 performed specific actions were data that mnemon 170 is stored, provide and give analytic unit 195, make it analyze the state of fan 150.By the analysis of analytic unit 195, just can learn the characteristic of fan 150, or infer the aging performance that fan 150.In a possibility embodiment, analytic unit 195 can be integrated among the control unit 110.
Fig. 3 is a possible flow chart of the present invention's controlling method.In the present embodiment, step S310 ~ S330 carries out under a start-up mode, and step S340 ~ S370 carries out under an operator scheme.At first, produce one first control signal (step S310).The present invention does not limit the type of first control signal.In a possibility embodiment, first control signal is a pulsewidth modulation (PWM) signal.
According to first control signal, produce a starting resistor and give fan (step S320).When fan receives starting resistor, just begin to rotate.At this moment, the rotating speed of fan is one first rotating speed.This first rotating speed may be the minimum speed of fan.Then, write down first rotating speed (step S330).In a possibility embodiment, first rotating speed can together be stored in a mnemon with starting resistor.
Then, produce one second control signal (step S340).Similarly, the present invention does not limit the type of second control signal.In a possibility embodiment, second control signal also may be a pulsewidth modulation (PWM) signal.
According to second control signal, produce an operating voltage and give fan (step S350).Fan rotates according to operating voltage.At this moment, the rotating speed of fan is one second rotating speed.This second rotating speed is greater than this first rotating speed.Then, write down second rotating speed (step S360).Second rotating speed can together be stored in a mnemon with operating voltage.
According to first and second rotating speed, carry out a specific action (step S370).The present invention does not limit, and carries out the time point of this specific action.One may embodiment in, when the gap between this first and second rotating speed during, just carry out this specific action less than a predefined value.
In addition, the present invention does not also limit the type of this specific action.In a possibility embodiment, this specific action is to drive loudspeaker, and these loudspeaker are sounded.Therefore, the user just can learn the working order of fan according to the sound that loudspeaker sent.In another embodiment, this specific action is the relation that presents between this first and second rotating speed.Therefore, the user can learn whether fan deterioration phenomenon takes place according to the relation between first and second rotating speed.
In other possibility embodiment, this specific action is to increase or reduce this operating voltage.For example, when fan was aging, second rotating speed may be slack-off.Therefore, can see through the mode that increases operating voltage, keep the usefulness of fan.In addition, also can see through the mode that reduces operating voltage, prolong the life-span of fan.
By first and second rotating speed that is write down, just can analyze fan state, and then infer the time point that the fan possible breakdown, in order to user ahead of time ready (more renewing fan).Therefore, improve convenience greatly.
