Embodiment
The embodiment of the present application, by a kind of method and a kind of electronic equipment that detects fan failure is provided, has solved in the prior art for the accurate not technical problem of the evaluation of fan failure.Effectively guaranteed the type of accurate judgement fan failure.
Technological scheme in the embodiment of the present application is for addressing the above problem, and general thought is as follows:
At first judge whether described fan breaks down;
In the situation that described fan breaks down, detect the first operational parameter value of described fan, such as fan noise;
Then based on the first operational parameter value, judge, which kind of fault that fan occurs on earth, such as: if fan noise is excessive, be that the running environment of fan goes wrong so, such as fan loss, illiteracy dirt etc.; And if fan noise is smaller, be that the quality of fan goes wrong so.
In order better to understand technique scheme, below in conjunction with Figure of description and concrete mode of execution, technique scheme is described in detail.
The application one embodiment provides the method that detects fan failure in, described method is applied in the electronic equipment that comprises fan, such as notebook computer, integrated machine or television set etc., for follow-up introduction convenience, in follow-up introduction, all take described electronic equipment as notebook computer is example, its implementation procedure is described in detail.
As shown in Figure 1, the method for described detection fan failure, comprise the steps:
S101: whether the running state that judges described fan meets for embodying pre-conditioned that whether described fan normally moves;
In specific implementation process, in the notebook computer start, in order to guarantee timely heat radiation, can open the fan of notebook computer simultaneously.After the fan operation, can adopt various ways to determine whether the running state of described fan meets for embodying pre-conditioned that whether described fan normally moves.
Below, introduce two kinds and judge the whether normally method of operation of fan, certainly, in specific implementation process, described method is not limited to following two kinds.
(1) whether judgement is greater than the first predetermined threshold value for the first parameter value that characterizes described rotation speed of the fan.
Suppose normal notebook computer, if in game state, the heat energy of generation is many, and its rotation speed of the fan should be generally: 2000 rev/mins.But but find that through detecting its rotation speed of the fan only has 600 rev/mins, in this case, just can determine that fault has appearred in fan.
(2) judge that whether the temperature of notebook computer is too high.
Suppose, notebook computer is in the electronic document editing mode, and in this case, the heat that computer produces is also few, and the temperature of notebook computer continuous high temperature always is likely just now that fan does not work.
S102: do not meet describedly when pre-conditioned in the running state of described fan, obtain the first operational parameter value of described fan by detection;
In specific implementation process, described the first operational parameter value that obtains described fan by detection is specifically as follows:
By detection, obtain for characterizing the second parameter value of described fan noise.
In specific implementation process, as shown in Figure 2, can obtain in the following way the second parameter value:
S201: the first sound that records described electronic equipment place environment;
Suppose, the first sound that has recorded a notebook computer comprises following part:
Ambient noise: 40dB
System noise, system noise comprises again:
Hard disk noise: 20dB
Fan noise: 30dB
CPU noise: 15dB
After based on step S201, recording the first sound, just can perform step: S202: filter out ambient noise from described the first sound, to obtain system noise;
S203: extract fan noise from described system noise, to obtain described the second parameter value.
The first sound based on obtaining in step S201 is known, and the second parameter value for characterizing described fan noise finally obtained is 30dB.
Obtaining the first operational parameter value based on step S102 namely after the second parameter value in step S203, just can perform step S103: based on described the first operational parameter value, determine the fault type of described fan.
In specific implementation process, described based on described the first operational parameter value, determine the fault type of described fan, can comprise following two kinds of situations:
(1) if described the first operational parameter value is greater than the second predetermined threshold value, determine that first kind fault appears in described fan, wherein, described first kind fault breaks down for the running environment that characterizes described fan.
Suppose that the second predetermined threshold value is 25dB, because the first operational parameter value obtained is 30dB, be greater than the second predetermined threshold value so, so determine that first kind fault appears in described fan, problem has appearred in the running environment that described fan namely is described, such as the long-pending full dust of fan, fan wearing and tearing etc.
In this case, can be adjusted the running environment of fan, such as the dust of removing the fan surface, removal cause the reason of fan wearing and tearing, thereby be extended the working life of fan.
(2) if described the first operational parameter value is less than described the second predetermined threshold value, determine that the Equations of The Second Kind fault appears in described fan, wherein, described Equations of The Second Kind fault breaks down for characterizing described fan quality.
Suppose that the second predetermined threshold value is 40dB, because the first operational parameter value obtained is 30dB, be less than in the second predetermined threshold value so, so determine that the Equations of The Second Kind fault appears in described fan, namely illustrate that the quality of described fan has problem.
In this case, may need fan is placed under repair, changes fan etc., thereby can not cause the heat radiation of electronic equipment abnormal because of the quality problems of fan, to electronic equipment, bring harm.
Certainly, in specific implementation process, for determining of fan failure, be not limited to above-mentioned two kinds.
The employing aforesaid way can carry out different disposal to fan by the fan failure based on different after determining the different faults type of fan, such as in the situation that fan covers dirt, removes the dust of fan; In the situation that the fan quality goes wrong, change fan etc., so convenient to the processing of fan failure, timely and targeted.
In specific implementation process, in some cases, after fan breaks down, possible user can not be processed the fault of fan in time, such as: the user is common notebook computer user, can't dismantle notebook computer, and nature cannot be cleared up the fan dust or change fan.In this case, can also be assessed the used remaining time of described fan, obtain an assessed value, described assessed value is for characterizing the remaining pot life of described fan.
Such as: the rotating speed of the notebook computer of front is 600 rev/mins, and its fan noise is 30dB, this explanation fan can also be brought into play heat sinking function, and its noise neither be too large, can not affect very much user's use, so estimate that the damage of this fan is also not serious, its remaining life is by longer.
And suppose a notebook computer at high temperature its rotating speed only have 200 rev/mins, and its fan noise reaches 70dB, in this case, the user of serious impact uses, and its heat sinking function is unsatisfactory, so its residue is used can be not oversize, now should to fan failure, deal with in time, in order to avoid notebook computer is worked the mischief.
Adopt the technological scheme of remaining pot life of above-mentioned assessment fan, can accurately learn in time the information of fan, thereby the different situation based on fan is carried out different disposal to fan, thereby process in time fan failure.
