The invention aims to solve the technical problem that the heat dissipation effect of a fan is reduced because the dust deposition condition of the fan cannot be detected by the conventional electronic equipment, so that manual work cannot clean dust in time, and the heat dissipation effect of the fan is reduced. The invention realizes the technical scheme of detecting and reminding the dust accumulation condition of the fan.
While a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than shown. Generally, a fan is preset in an electronic device, the electronic device generates heat for a long time, and the fan can dissipate heat of the electronic device, so that the electronic device can maintain a good working state. The time is long, dust can be accumulated on fan blades of the fan in the electronic equipment, the more the dust is gathered on the fan blades, the dust increases the weight of the fan blades, the resistance of the fan to rotate increases, the rotating speed of the fan is reduced, and the heat dissipation effect of the fan on the electronic equipment is also reduced. Based on the above, the invention provides a dust removal reminding method for electronic equipment, which is used for detecting and reminding dust deposition on a fan with a heat dissipation effect.
As shown in fig. 2, in a first embodiment of the present invention, the electronic device dust removal reminding method includes the following steps:
step S210: and acquiring a plurality of target duty ratios, and controlling the fan in the electronic equipment to operate according to each target duty ratio.
Step S220: and detecting a first actual rotating speed of the corresponding fan when the fan is controlled according to each target duty ratio.
In this embodiment, the electronic device may irregularly detect the dust deposition condition of the fan, and start the dust removal reminding method when the dust deposition condition detection time of the fan is reached.
Specifically, the target duty cycles are multiple, the target duty cycles may be pre-stored in the electronic device, or may be sent to the electronic device by an external device, and the external device may perform data interaction with the electronic device, for example, a device such as a mobile device or a PC, a test apparatus, and the like. The target duty ratio can be understood as the duty ratio for controlling the operation of the fan under the condition that the heat dissipation effect of the fan is good. Each target duty cycle corresponds to one target rotating speed, the target duty cycles are different, and the target rotating speeds corresponding to the target duty cycles are also different. The intervals of any two adjacent target duty ratios are the same. For example, the target duty ratios are 4, 75%, 80%, 85%, and 90%, respectively, and the interval between any two adjacent target duty ratios is 5%. The interval between two adjacent target duty cycles may be set according to the implementation of the electronic device or the fan.
When the electronic equipment executes the electronic equipment dust removal reminding method, a plurality of target duty ratios are obtained, and then the fans are controlled to operate respectively according to the size sequence of the obtained target duty ratios. For the same target duty ratio, the fan is controlled to operate for a certain time, and the time for operating the fan at different target duty ratios can be the same or different.
And when the fans are respectively controlled to operate according to the obtained target duty ratios, detecting first actual rotating speeds of the corresponding fans under the target duty ratios, wherein the first actual rotating speeds are the actual rotating speeds measured when the fans operate at the target duty ratios. And detecting a plurality of real-time rotating speeds for the same target duty ratio, wherein the plurality of real-time rotating speeds are not necessarily the same and may not be the same, and taking the average value of the plurality of measured real-time rotating speeds as the first actual rotating speed.
Step S230: and acquiring the test rotating speed corresponding to each test duty ratio which is the same as each target duty ratio according to a preset corresponding relation.
In this embodiment, the preset corresponding relationship is a corresponding relationship between each test duty cycle of the fan and the test rotation speed corresponding to each test duty cycle when the electronic device meets the preset noise index and the preset dust deposition degree. In actual operation of the fan, the more dust on the fan blades is collected, the more noise is generated by the rotation of the fan, and the dust deposition degree of the fan can be measured through the noise. The preset noise indexes and the preset dust deposition degrees can be determined according to the actual conditions of the electronic equipment, for the same electronic equipment, each preset noise index corresponds to one preset dust deposition degree, under the preset dust deposition degree corresponding to the same preset noise index and the preset noise index, the fan has a critical duty ratio and a critical rotating speed corresponding to the critical duty ratio, if the rotating speed of the fan exceeds the critical rotating speed, the noise of the electronic equipment exceeds the preset noise indexes, and the user experience is poor; if the rotation speed of the fan is lower than the critical rotation speed, the heat dissipation effect of the fan will be reduced due to the reduction of the rotation speed. Under the same preset noise index and the preset dust deposition degree corresponding to the preset noise index, a critical duty ratio and a critical rotating speed corresponding to the critical duty ratio exist, the test duty ratio in the preset corresponding relation is equal to or lower than the critical duty ratio, and the test rotating speed corresponding to the test duty ratio is equal to or lower than the critical rotating speed corresponding to the critical duty ratio.
Step S240: and acquiring the target number of the first actual rotating speed smaller than each test rotating speed on the basis of the target duty ratio which is the same as each test duty ratio.
Step S250: and outputting dust removal reminding information when the target number is greater than or equal to the preset number.
In the embodiment, the fan is controlled to operate according to each target duty ratio, after a plurality of first actual rotating speeds under each target duty ratio are detected, the target number of the first actual rotating speeds which are smaller than each test rotating speed and are measured under the target duty ratio which is the same as each test duty ratio is respectively counted, if the target number is larger than or equal to the preset number, the situation that dust is seriously accumulated on the fan and the heat dissipation effect of the fan is poor, dust removal needs to be carried out, namely dust removal reminding is output, and the fan is manually carried out through the dust removal reminding prompt; the dust removal reminder comprises one or more of sound, text information, light and vibration.
In one embodiment, the target duty cycles have 3, P11, P12, P13. When the fan runs at the target duty ratios P11, P12 and P13, the first actual rotating speeds of the fan are respectively measured as V11, V12 and V13. In the preset corresponding relation, the test rotation speed corresponding to the test duty ratio C11 is R11, the test rotation speed corresponding to the test duty ratio C12 is R12, and the test rotation speed corresponding to the test duty ratio C13 is R13. Where P11 equals C11, P12 equals C12, and P13 equals C13. The preset number is set to 3, and the sizes of V11 and R11, V12 and R12, and V13 and R13 are compared, respectively. If V11< R11, V12< R12 and V13< R13, the target number is 3, and then the reminding dust removal information is sent out.
In another example, the target duty cycles have 3, P21, P22, P23, respectively. When the fan runs at the target duty ratio P21, the first actual rotation speeds of the fan measured three times are respectively (V21, V22 and V23), and the average value of the first actual rotation speeds is V1; when the fan runs at the target duty ratio P22, the first actual rotation speeds of the fan measured three times are respectively (V24, V25 and V26), and the average value of the first actual rotation speeds is V2; when the fan runs at the target duty ratio P23, the first actual rotation speeds of the fan measured three times are respectively (V27, V28, V29), and the average value thereof is V9. In the preset corresponding relation, the test rotation speed corresponding to the test duty ratio C21 is R21, the test rotation speed corresponding to the test duty ratio C22 is R22, and the test rotation speed corresponding to the test duty ratio C23 is R23. Where P21 equals C21, P22 equals C22, and P23 equals C23. The preset number is set to 2, and the sizes of V1 and R11, V2 and R12, and V3 and R13 are compared, respectively. If V1< R11 and V3< R23, the target number is 2, and reminding dust removal information is sent.
According to the technical scheme, the dust deposition condition of the fan is detected, when the heat dissipation effect of the fan is reduced due to the fact that the dust deposition of the fan is serious is detected, the dust removal reminding can be timely sent to remind people of manual fan dust removal intervention, so that normal work of electronic equipment is maintained, and the electronic equipment is favorably prevented from being abnormal due to the reduction of the heat dissipation effect of the fan.
As shown in fig. 3, the dust removal reminding method for electronic equipment of the present invention further includes the following steps:
step S110: when the electronic equipment is started for the first time, acquiring a plurality of different initial duty ratios of the fan, and controlling the fan to operate according to the plurality of different initial duty ratios;
step S120: acquiring second actual rotating speeds of the fan corresponding to a plurality of different initial duty ratios;
step S130: and when the second actual rotating speed is the same as the reference rotating speed corresponding to the reference duty ratio and the reference duty ratio corresponding to the reference rotating speed which is the same as the second actual rotating speed is different from the initial duty ratio, adjusting the initial duty ratio to be the reference duty ratio.
In the actual production of the fan, the fan is produced in batches according to the standard of a fan prototype, the fan prototype is designed in advance, and the parameter of each fan product produced in subsequent batches is set according to the fan prototype, so that the reference duty ratio of the fan prototype is set as the operation parameter of each produced fan. Because each fan in mass production is not completely the same, and there is a difference in rationality in the hardware of each fan, after setting a reference duty ratio for operation for each fan, when each fan is working, it is not necessarily operating according to the reference duty ratio, so that it is necessary to correct the duty ratio for controlling the operation of the fan when each fan is first operated after the fan is put into practical use, so as to make the fan accurately operate. The duty ratio for controlling the fan to operate is referred to as an initial duty ratio, and each initial duty ratio corresponds to an initial rotating speed.
Usually, after the electronic device is turned on, the fan is turned on accordingly, that is, whether the fan is operated for the first time is determined by detecting whether the electronic device is turned on for the first time. When the electronic equipment is started for the first time, namely the fan operates for the first time, a plurality of different initial duty ratios of the fan are obtained, the fan operates according to the plurality of different initial duty ratios, and the second actual rotating speed of the fan corresponding to the plurality of different initial duty ratios is detected, namely the second actual rotating speed is the actual rotating speed corresponding to the fan when the fan operates for the first time and the fan operates at the plurality of different initial duty ratios.
After the second actual rotating speed corresponding to each initial duty ratio is obtained, the reference rotating speed which is the same as the second actual rotating speed is obtained, and if the reference duty ratio corresponding to the reference rotating speed which is the same as the second actual rotating speed is different from the initial duty ratio corresponding to the second actual rotating speed, the initial duty ratio needs to be adjusted to the reference duty ratio. If the fan operates according to the adjusted initial duty ratio and the fan works normally, the initial rotating speed corresponding to the adjusted initial duty ratio is a second actual rotating speed and is also a reference rotating speed. For example, the plurality of different initial duty ratios are W1, W2, W3, respectively, the second actual rotational speeds detected by operating the fan according to W1, W2, W3 are v11, v22, v33, respectively, the plurality of reference duty ratios are D1, D2, D3, and the reference rotational speeds corresponding to D1, D2, D3 are v01, v02, v03, respectively. Wherein v11 ═ v01, v22 ═ v02, v33 ═ v03, that is, W1, W2, W3 are adjusted, and W1, W2, W3 after adjustment are W1 ', W2', W3 ', W1 ═ D1, W2 ═ D2, W3 ═ D3, that is, W1', W2 ', W3' respectively correspond to initial rotation speeds v11, v22, v 33.
Furthermore, after the initial duty ratio of the fan is adjusted, the initial duty ratio of the fan is corrected, and the fan can operate according to the corrected initial duty ratio (namely, the reference duty ratio), so that the accuracy of the operation of the fan is improved. Based on the method, when the fan needs to be dedusted in an unscheduled detection, the target duty ratio is selected from the reference duty ratios to control the fan to operate, and whether the fan needs to be dedusted is further judged, namely the target duty ratio is selected from the reference duty ratios.
As shown in fig. 4, the process of establishing the preset corresponding relationship includes the following steps:
step 310: under the condition that the electronic equipment meets the preset dust deposition degree, controlling the fan to operate according to a plurality of different test duty ratios, and respectively detecting noise values generated by the fan;
step 320: and when the noise value does not exceed the preset noise index, correlating the corresponding test duty ratio with the test rotating speed corresponding to the test duty ratio to obtain the preset corresponding relation.
The condition of presetting the deposition degree can be obtained through the deposition condition of simulation fan, because behind the flabellum gathering dust of fan, influence the fan pivoted resistance increase promptly, the fan can produce the noise simultaneously, so the resistance that the fan rotation received can be equivalent to external resistance, can be through the condition of exerting different external resistance in order to simulate presetting the deposition degree to the flabellum of fan promptly. In addition, the condition of the preset dust deposition degree can also be determined according to the actual dust deposition condition of the fan, and the condition of the preset dust deposition degree is determined when the heat dissipation effect of the fan begins to decline by monitoring the dust deposition amount of fan blades in real time.
Specifically, under the condition that the electronic equipment meets the preset dust deposition degree, the fans are controlled to operate according to a plurality of different test duty ratios, noise values generated by the fans when the fans operate according to the different test duty ratios are detected respectively, then the obtained noise values are compared with preset noise indexes, and if the noise values are smaller than or equal to the preset noise indexes, the corresponding test duty ratios and the test rotating speeds corresponding to the test duty ratios are correlated to obtain a preset corresponding relation.
Further, step S250 is followed by: and controlling the fan to run at a critical duty ratio until the dust removal operation is finished.
Considering that if the dust removal reminding information is output, the fan cannot be manually dedusted in time, the electronic equipment still needs to work within corresponding time, and based on the operation, the fan is controlled to operate according to the critical duty ratio, so that the rotating speed of the fan is increased under the condition of dust deposition of the fan, the fan can continue to radiate heat for the electronic equipment, and after the manual dedusting of the fan is detected to be completed, the fan is controlled to operate according to the reference duty ratio. The critical duty ratio is a test duty ratio of the fan operation when the noise value is equal to a preset noise index, the test rotating speed corresponding to the test duty ratio is a critical rotating speed corresponding to the critical duty ratio, the critical duty ratio is greater than or equal to the test duty ratio in the preset corresponding relation, and the critical rotating speed corresponding to the critical duty ratio is greater than or equal to the test rotating speed corresponding to the test duty ratio in the preset corresponding relation.
Further, step S250 is followed by:
determining a maximum target duty cycle of a plurality of the target duty cycles;
and increasing the maximum target duty ratio according to a preset increment, and controlling the fan to operate according to the increased maximum target duty ratio so that a first actual rotating speed measured when the fan is operated at the increased maximum target duty ratio reaches a target rotating speed corresponding to the maximum target duty ratio. The size of the preset increment can be obtained according to the difference between the maximum target duty ratio and the critical duty ratio. For example, when the difference between the maximum target duty ratio and the critical duty ratio is 1% to 5%, the preset increment is 1%; when the difference value between the maximum target duty ratio and the critical duty ratio is 3% -5%, the preset increment is 3%. The larger the difference between the maximum target duty cycle and the critical duty cycle, the larger the value of the preset increment.
Considering that if the dust removal reminding information is output, the fan cannot be subjected to dust removal operation manually in time, and the electronic equipment still needs to work within corresponding time, on the basis, the maximum target duty ratio is obtained from the plurality of target duty ratios, then the maximum target duty ratio is increased, and the fan is controlled to operate according to the increased maximum target duty ratio, so that the first actual rotating speed measured when the fan is operated at the maximum target duty ratio reaches the target rotating speed corresponding to the maximum target duty ratio, the rotating speed of the fan can be increased under the condition of dust accumulation of the fan, the fan can rotate at a higher rotating speed, and a good heat dissipation effect is kept. Wherein the target duty cycle is greater than the critical duty cycle.
