Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method and apparatus for adjusting a rotational speed of a fan, an electronic device, and a readable storage medium.

Along with the continuous powerful functions of the electronic equipment, the power consumption in the running process is increased, so that the heat dissipation problem of the electronic equipment is more and more important.

At present, aiming at the heat dissipation problem of electronic equipment, an air cooling heat dissipation device is generally arranged in the electronic equipment to perform heat dissipation treatment; such as fan-based air dissipation for electronic devices.

However, when using the electronic device, the user may have a use scene such as being placed on an irregular table surface (such as on a leg) besides a use scene of a horizontal table surface such as an office table, so that an air inlet of the electronic device is blocked to cause a poor heat dissipation effect, thereby causing the whole machine to generate heat and shortening the use time of the electronic device.

Disclosure of Invention

The application provides an earphone connecting system, an earphone connecting method, an earphone, electronic equipment and a readable storage medium, which can improve the heat dissipation effect of the electronic equipment and prolong the service time of the electronic equipment.

In order to achieve the above purpose, the application adopts the following technical scheme:

in a first aspect, a method of adjusting a rotational speed of a fan is provided, the method may include:

the electronic equipment acquires the first air inlet quantity of the first fan and the second air inlet quantity of the second fan; and if the first air quantity difference exists between the first air quantity and the second air quantity under the same initial rotating speed, respectively adjusting the rotating speed of the first fan and the rotating speed of the second fan based on the first air quantity difference.

For example, when an electronic device is placed on a non-horizontal irregular counter top for use, problems may arise that block the air intake of the fan of the electronic device due to the irregularities of the counter top; based on the detection of the air inlet quantity of each fan, whether the air inlets are blocked or not can be judged, if the air inlet quantity of the two fans at the same rotating speed is different, one of the air inlets is possibly blocked, the rotating speed of the fans can be adjusted based on the respective air inlet quantity, for example, the rotating speed of the fan with the blocking is reduced, and the rotating speed of the other fan is increased, so that the radiating efficacy of the electronic equipment is ensured.

Through the mode, whether the air inlet is shielded is judged by detecting whether the air inlet quantity of different fans is the same or not, and the respective rotating speeds are adjusted based on the air inlet quantity of each fan, so that the power consumption of the shielded fan is reduced and the service time of the electronic equipment is prolonged while the heat dissipation effect of the electronic equipment is ensured.

In a possible implementation manner of the first aspect, if there is a first air volume difference between the first air volume and the second air volume, the electronic device adjusts the rotation speed of the first fan and the rotation speed of the second fan based on the first air volume difference, respectively, including:

If the first air inlet quantity is smaller than the second air inlet quantity, the electronic equipment adjusts the rotating speed of the first fan to be a first rotating speed based on the first air inlet quantity difference value, and adjusts the rotating speed of the second fan to be a second rotating speed; the first rotating speed is smaller than the initial rotating speed, and the second rotating speed is larger than the initial rotating speed.

By the method, when the air inlet of the first fan is smaller than the air inlet of the second fan at the same rotating speed, the rotating speed of the first fan is reduced, and the rotating speed of the second fan is improved, so that the heat dissipation effect of the electronic equipment is ensured by improving the air inlet of the second fan, and meanwhile, the rotating speed of the first fan is reduced, and the power consumption of the electronic equipment is saved; therefore, the influence of the shielding of the air inlet of the fan on the heat dissipation effect is reduced, the speed of heat accumulation generated by the electronic equipment is slowed down, and the service time of the electronic equipment is prolonged.

In a possible implementation manner of the first aspect, the electronic device adjusts a rotation speed of the first fan to a first rotation speed and adjusts a rotation speed of the second fan to a second rotation speed based on the first air volume difference value, including:

based on the first air volume difference value, the electronic equipment determines a rotating speed adjustment value matched with the first air volume difference value; the electronic equipment adjusts the rotating speed of the first fan to be a first rotating speed and adjusts the rotating speed of the second fan to be a second rotating speed based on the rotating speed adjusting value; the first rotation speed is the rotation speed after the initial rotation speed is reduced by the rotation speed adjustment value, and the second rotation speed is the rotation speed after the initial rotation speed is increased by the rotation speed adjustment value.

Through the mode, the rotating speed adjusting value matched with the first air quantity difference value is determined, so that the rotating speeds of the first fan and the second fan can be adjusted more reliably, the heat dissipation effect of the electronic equipment reaches a better state, and meanwhile, the power consumption generated by the shielded fan is reduced, so that the balance between the heat dissipation function and the generated power consumption can be controlled more reliably and accurately.

In a possible implementation manner of the first aspect, after the electronic device obtains the first air intake of the first fan and the second air intake of the second fan, the method further includes:

if the first air inlet quantity is the same as the second air inlet quantity at the same initial rotating speed, and the first air inlet quantity and the second air inlet quantity are not matched with the initial rotating speed, the electronic equipment acquires a second air quantity difference value between the first air inlet quantity, the second air inlet quantity and the default air inlet quantity; the electronic equipment respectively adjusts the rotating speeds of the first fan and the second fan according to the same rotating speed adjusting value based on the second air volume difference value; the default air inlet quantity is the air inlet quantity matched with the initial rotating speed.

The electronic equipment stores a corresponding relation between the rotating speed and the air inlet quantity, namely the corresponding relation between the rotating speed and the air inlet quantity under the condition of normal non-shielding; when the air inlet amounts of the first fan and the second fan are the same, but the air inlet amount and the current rotating speed do not meet the corresponding relation of mutual matching, if the current air inlet amount is smaller than the air inlet amount matched with the current rotating speed, the two fans are possibly shielded to the same extent, and the rotating speeds of the two fans are adjusted to the same extent by the electronic equipment, for example, the rotating speeds of the two fans are simultaneously increased by corresponding rotating speed adjusting values.

Through the mode, when the working states of the two fans are the same, the same air inlet quantity is kept at the same rotating speed, and the air inlet quantity is smaller than the expected air inlet quantity matched with the rotating speed, the rotating speeds of the two fans are adjusted through the same adjusting strategy, and under the condition that the fans are possibly shielded to the same extent, the heat dissipation effect of the electronic equipment is ensured, the heat accumulation speed of the whole machine is slowed down, and the service time of the electronic equipment is prolonged.

if the first air quantity difference value exists between the first air quantity and the second air quantity at the same initial rotating speed, the electronic equipment acquires a temperature value output by the temperature detection module; the electronic equipment adjusts the rotating speed of the first fan and the rotating speed of the second fan respectively based on the first air volume difference value and the temperature value.

The application can also make a strategy for adjusting the rotating speed of the fan based on the air inlet quantity of the fan and combining with a temperature detection module of the electronic equipment. The electronic device may further store heat dissipation coefficients corresponding to different temperature values, where the heat dissipation coefficients correspond to rotational speeds of the fans, and adjust rotational speeds of the first fan and the second fan based on the heat dissipation coefficients corresponding to the temperature values and the current first air volume difference.

if the first air volume difference value exists between the first air volume and the second air volume at the same initial rotating speed, the first air volume of the first fan is not matched with the initial rotating speed or the second air volume of the second fan is not matched with the initial rotating speed, and the electronic equipment acquires a temperature value output by the temperature detection module; the electronic equipment adjusts the rotating speed of the first fan and the rotating speed of the second fan respectively based on the first air volume difference value and the temperature value.

For example, when the air inlet of the fan is not matched with the initial rotation speed and the air inlets of the two fans respectively correspond to each other, it is indicated that the air inlets of the fans may be shielded to different degrees; based on the air volume difference and the temperature value output by the temperature detection module, the rotating speed of each fan is further and more accurately adjusted.

Through the mode, when one or two fans are shielded, the rotating speed of the fans can be correspondingly adjusted by combining the temperature values output by the temperature detection module, so that the rotating speed of the fans can be more specifically adjusted by combining the temperature values under the shielding condition of the fans, and the heat dissipation effect of the electronic equipment is further optimized.

In a possible implementation manner of the first aspect, the electronic device adjusts a rotation speed of the first fan and a rotation speed of the second fan based on the first air volume difference value and the temperature value, respectively, including:

the electronic equipment calculates a first temperature difference value between the temperature value and a preset first temperature threshold value; the electronic equipment calculates a first adjusting value corresponding to the first fan and a second adjusting value corresponding to the second fan based on the first air volume difference value and the first temperature difference value; the electronic device adjusts the rotation speed of the first fan based on the first adjustment value, and adjusts the rotation speed of the second fan based on the second adjustment value.

By the method, the temperature difference of the current working temperature of the electronic equipment from the highest temperature threshold value and the air inlet difference of the two fans are monitored, and the rotating speed adjustment values corresponding to the fans are calculated respectively, so that the heat dissipation control effect is more reliable and accurate, and the service time of the electronic equipment for normal operation can be prolonged to the greatest extent.

In a possible implementation manner of the first aspect, after the electronic device adjusts the rotation speed of the first fan and the rotation speed of the second fan based on the first air volume difference value and the temperature value, the method further includes:

the electronic equipment obtains the total air inlet quantity of the first fan and the second fan at the nth sampling moment and a first temperature value output by the temperature detection module; the electronic equipment calculates a second temperature difference value between the first temperature value and a second temperature value output by the temperature detection module at the n-1 th sampling moment; the electronic device adjusts the rotation speeds of the first fan and the second fan based on the total air inlet quantity at the nth sampling time and the second temperature difference value.

Through the mode, the electronic equipment periodically monitors the air inlet and the working temperature value, the rotating speed of the fan can be adjusted more flexibly along with the change condition of the temperature of the whole machine, so that the heat dissipation treatment is more in line with the actual application scene, the better heat dissipation effect is realized, and the service time of the electronic equipment is longer.

In a possible implementation manner of the first aspect, the electronic device adjusts the rotation speeds of the first fan and the second fan based on the total air intake at the nth sampling time and the second temperature difference value, including:

if the second temperature difference value is larger than the second temperature threshold value, the electronic equipment adjusts the rotating speeds of the first fan and the second fan so that the total air inlet quantity of the first fan and the second fan reaches the total required air inlet quantity corresponding to the first temperature value; if the second temperature difference is smaller than the second temperature threshold, the electronic equipment controls the first fan and the second fan to keep at the rotating speed corresponding to the total air inlet quantity at the nth sampling moment.

Through the mode, the rotating speed of the fan is dynamically adjusted based on the temperature change conditions at different sampling moments, the air quantity matched with the working temperature of each component is provided at any time, and the heat dissipation effect of the whole machine is ensured.

if the first air volume difference exists between the first air volume and the second air volume, the electronic equipment adjusts the clock frequency or the power supply voltage of the processor based on the first air volume difference; the electronic equipment adjusts the rotating speeds of the first fan and the second fan based on the adjusted clock frequency or power supply voltage of the processor and the first air volume difference value.

By the mode, due to the fact that the air inlet quantity is poor in air quantity, the fact that the air inlet of at least one fan is blocked is indicated; when the air inlet of the fan is shielded, the clock frequency or the power supply voltage of the processor can be reduced, so that the power consumption of the electronic equipment is reduced by reducing the calculation force; based on the parameters after the running state is adjusted, the rotating speed of the fan is comprehensively adjusted, so that the heat dissipation function is matched with the running phase of the whole machine, and the heat dissipation effect is better.

In a possible implementation manner of the first aspect, if there is a first air volume difference between the first air volume and the second air volume, the electronic device adjusts a clock frequency or a power supply voltage of the processor based on the first air volume difference, including:

If the first air inlet quantity is smaller than the second air inlet quantity and the first air inlet quantity difference value is smaller than the difference threshold value, the electronic equipment adjusts the clock frequency of the processor from the initial clock frequency to the first clock frequency or adjusts the initial power supply voltage of the processor to the first power supply voltage; if the first air inlet volume is smaller than the second air inlet volume and the first air inlet volume difference value is larger than or equal to the difference threshold value, the electronic equipment adjusts the clock frequency of the processor from the initial clock frequency to the second clock frequency or adjusts the initial power supply voltage of the processor to the second power supply voltage.

The first clock frequency and the second clock frequency are both smaller than the initial clock frequency, and the second clock frequency is smaller than the first clock frequency; the first power supply voltage and the second power supply voltage are smaller than the initial power supply voltage, and the second power supply voltage is smaller than the first power supply voltage.

By the method, the shielding degree of the air inlet of the fan can be determined based on the air volume difference, so that the running state of the processor is selectively adjusted based on the shielding degree of the air inlet, and when the air volume difference is large, the reduced clock frequency or the reduced power supply voltage is more; when the air volume difference is smaller, the reduced clock frequency or the reduced power supply voltage is relatively smaller; thereby ensuring the heat dissipation effect of the whole machine while ensuring the running state of the whole machine.

In a possible implementation manner of the first aspect, the electronic device adjusts the rotation speeds of the first fan and the second fan based on the adjusted clock frequency or the adjusted power supply voltage of the processor and the first air volume difference value, including:

if the adjusted clock frequency of the processor is the first clock frequency or the power supply voltage is the first power supply voltage, the electronic equipment adjusts the rotating speed of the first fan to be the third rotating speed, and adjusts the rotating speed of the second fan to be the fourth rotating speed; and if the adjusted clock frequency of the processor is the second clock frequency or the power supply voltage is the second power supply voltage, adjusting the rotating speed of the first fan to be the fifth rotating speed and adjusting the rotating speed of the second fan to be the sixth rotating speed.

The third rotating speed is larger than the fifth rotating speed, the fourth rotating speed is smaller than the sixth rotating speed, the third rotating speed is smaller than the fourth rotating speed, and the fifth rotating speed is smaller than the sixth rotating speed.

According to the mode, based on the air inlet quantity of the electronic equipment, the clock frequency or the power supply voltage of the processor is adjusted to reduce the calculation force of the electronic equipment; then further adjusting the rotating speed of the fan along with the adjusted working state; therefore, the total calculation force can be reduced under the condition that the fan is possibly shielded, the power consumption of the electronic equipment is reduced, the better heat dissipation effect is realized by adjusting the rotating speed of the fan, the speed of the temperature rise of the electronic equipment is effectively slowed down, the running state of the electronic equipment and the heat dissipation effect of the fan are better matched and balanced, and the service time of the electronic equipment is effectively prolonged.

According to the embodiment of the application, based on the air inlet quantity of the heat radiating device of the electronic equipment, the working temperature of each part and the working state of the processor measured by the temperature detection module, the corresponding rotation speed adjustment or the adjustment of the working state of the processor is carried out in a single and combined mode, so that the rotation speed of the fan is more flexibly adjusted, the heat radiating treatment is more suitable for the actual application scene, the heat radiating effect is better realized, the temperature rising speed of the electronic equipment is effectively slowed down, the running state of the electronic equipment and the heat radiating effect of the fan are better matched and balanced, and the service time of the electronic equipment is effectively prolonged. The following describes a specific implementation manner of adjusting the rotation speed of the fan according to the present application through an embodiment.

Example 1

Referring to fig. 3, a flow chart of a method for adjusting a rotational speed of a fan according to an embodiment of the application is shown; the embodiment of the application adjusts the rotating speed of the fan based on the air inlet quantity and the air quantity difference value. As shown in fig. 3, the method for adjusting the rotation speed of the fan may include the following steps:

s301, the electronic equipment acquires the first air inlet quantity of the first fan and the second air inlet quantity of the second fan.

S302, if a first air volume difference exists between the first air volume and the second air volume at the same initial rotation speed, the rotation speed of the first fan and the rotation speed of the second fan are respectively adjusted based on the first air volume difference.

In some embodiments, the electronic device may be a mobile terminal device such as a notebook computer configured with a heat sink. The initial rotational speed may be a rotational speed of the electronic device when the electronic device obtains the air intake at any sampling time, including but not limited to a rotational speed of the electronic device when the electronic device starts to operate after being started.

Due to the problem of placing the working table surface of the electronic device, the electronic device may be flexibly placed on the working table surface in various application scenes, such as a table surface of a person's leg or a sofa, which is easy to block the air inlet of the heat dissipating device. At this time, the air inlet of the heat dissipating device of the electronic device is easily blocked, and the air inlet is affected, so that the heat dissipating effect of the electronic device is affected. When the electronic equipment is provided with a plurality of heat dissipation devices, the air inlets corresponding to different heat dissipation devices can be shielded to the same or different degrees; for example, when the electronic device is configured with two or more heat dissipating fans, the air inlets of the heat dissipating fans configured at different positions may be blocked to different degrees due to irregularities of the work surface.

The electronic device may periodically obtain the air intake information of the fan acquired by the air intake sensor, and obtain the rotation speed of the fan at the corresponding sampling time; and dynamically adjusting the rotating speed of the fan or maintaining the current rotating speed of the fan based on the air inlet quantity information and the acquired rotating speed.

For example, taking an electronic device configured with two heat dissipation fans as an example, if the two fans have differences in air intake under the same initial rotation speed, it is indicated that at least one of the two fans has a certain degree of shielding, and the electronic device adjusts the rotation speed of the fans based on the differences in the air intake of the two fans so as to match the current running state of the electronic device, thereby improving the heat dissipation capacity of the whole machine, achieving a better heat dissipation effect and reducing the power consumption of the whole machine.

It should be noted that, in the embodiment of the present application, only two fans are taken as an example, and a manner of adjusting the rotation speed of the fans is illustrated, so that the number and the positions of the cooling fans configured in the electronic device are not limited, and when the electronic device is configured with a plurality of fans, the fan speed adjustment method provided in the embodiment of the present application can be implemented based on the fan identifiers at different positions and the corresponding rotation speeds and air volumes.

According to the embodiment of the application, under the same fan rotating speed, whether the air inlet quantity of different fans is the same is detected, whether the air inlet is shielded is judged, the rotating speeds of the fans are adjusted based on the air inlet quantity of the fans, the heat dissipation effect of the electronic equipment is ensured, the power consumption of the shielded fans is reduced, and the service time of the electronic equipment is prolonged.

In some embodiments, if the first air intake is smaller than the second air intake, the electronic device adjusts the rotation speed of the first fan to a first rotation speed and adjusts the rotation speed of the second fan to a second rotation speed based on the first air intake difference; the first rotating speed is smaller than the initial rotating speed, and the second rotating speed is larger than the initial rotating speed.

For example, if the first air intake is less than the second air intake, then there is a blockage of the first fan, and there is more shielding than the second fan when the second fan may be blocked; the second fan may also be unobstructed. The rotation speed of the first fan is reduced, i.e. adjusted to the first rotation speed, and the rotation speed of the second fan is increased, i.e. adjusted to the second rotation speed.

The rotation speed of the first fan is reduced and the rotation speed of the second fan is increased, the rotation speeds of the first fan and the second fan can be adjusted by adjusting the driving currents of the first fan and the second fan, for example, the driving currents of the first fan and the second fan corresponding to the initial rotation speeds are all 3 milliamperes, when one of the fans is detected to be shielded, the driving current of the first fan is adjusted to be 1 milliampere, and the driving current of the second fan is adjusted to be 5 milliamperes. Thereby reducing the power consumption of the whole machine while improving the heat dissipation capacity of the whole machine.

The integral air inlet quantity of the electronic equipment is ensured by increasing the rotating speed of the fan without shielding or with low shielding degree, so that the heat dissipation effect of the electronic equipment is ensured; in addition, the rotating speed of the first fan is reduced, and the power consumption of the electronic equipment is saved; therefore, the influence of the shielding of the air inlet of the fan on the heat dissipation effect is reduced, the speed of heat accumulation generated by the electronic equipment is slowed down, and the service time of the electronic equipment is prolonged.

In some embodiments, based on the first air volume difference, the electronic device determines a rotational speed adjustment value that matches the first air volume difference; the electronic equipment adjusts the rotating speed of the first fan to be a first rotating speed and adjusts the rotating speed of the second fan to be a second rotating speed based on the rotating speed adjusting value; the first rotation speed is the rotation speed after the initial rotation speed is reduced by the rotation speed adjustment value, and the second rotation speed is the rotation speed after the initial rotation speed is increased by the rotation speed adjustment value.

The electronic device stores a rotation speed adjustment value corresponding to the air volume difference value when the air volume difference value is in a preset air volume interval, so that the rotation speed adjustment value can be determined based on the preset air volume interval corresponding to the first air volume difference value, and the rotation speeds of the first fan and the second fan can be adjusted based on the rotation speed adjustment value.

The rotation speed adjustment value corresponding to the preset air volume interval can be calculated based on the total air volume matched with the current running state of the electronic equipment. For example, when the air volume difference is large, the fan with relatively small air volume can be turned off, the rotating speed of the fan with large air volume can be increased, and the rotating speed adjustment value is determined based on the air volume difference, so that the total air volume after adjustment is equal to or larger than the total air volume before adjustment.

As shown in fig. 4, an overall flow chart of a method for adjusting a rotation speed of a fan according to an embodiment of the present application is that different fans are used to detect an air intake of the fan and determine whether the air intake corresponding to the different fans is the same when the different fans keep the same rotation speed; when the air inlet quantity is the same, the fans are kept in the same scheduling strategy, and the same scheduling strategy can comprise the same rotation speed adjustment; the method comprises the steps of simultaneously improving the same rotating speed when different fans are shielded to the same extent, or eliminating the condition of recovering the original rotating speed when the shielding is carried out, adjusting the same rotating speed, and ending the adjustment turn of sampling and detecting the air inlet quantity at the time. When the air inlet amounts are different, different scheduling is carried out on each fan according to the air inlet amount conditions of different fans, namely the rotating speeds of the fans are respectively adjusted based on different air inlet amounts and the difference of the air inlet amounts; for example, the rotation speed of the fan with high air inlet is increased, the rotation speed of the fan with low air inlet is reduced, and the adjustment turn of sampling and detecting the air inlet is ended.

The rotation speed adjusting value matched with the first air quantity difference value is determined, so that the rotation speeds of the first fan and the second fan can be adjusted more reliably, the heat dissipation effect of the electronic equipment reaches a better state, and meanwhile, the power consumption generated by the shielded fan is reduced, so that the balance between the heat dissipation function and the generated power consumption can be controlled more reliably and accurately.

Example two

Referring to fig. 5, a flowchart of a specific implementation of a method for adjusting a rotational speed of a fan according to an embodiment of the present application is shown; in the embodiment, the fan rotating speed adjusting process is realized when the air inlets corresponding to different fans are all shielded to the same extent.

As shown in fig. 5, the method for adjusting the rotation speed of the fan may include the following steps:

s501, the electronic equipment acquires the first air inlet quantity of the first fan and the second air inlet quantity of the second fan.

S502, if the first air inlet volume is the same as the second air inlet volume at the same initial rotation speed, and the first air inlet volume and the second air inlet volume are not matched with the initial rotation speed, obtaining a second air inlet volume difference value of the first air inlet volume, the second air inlet volume and the default air inlet volume.

S503, based on the second air volume difference, the electronic device adjusts the rotation speeds of the first fan and the second fan respectively with the same rotation speed adjustment value.

In some embodiments, the electronic device obtains the intake air volume of each fan through an intake air volume sensor disposed corresponding to the fan. In one possible scenario, the first fan and the second fan are shielded to the same extent. The electronic equipment stores default air inlet quantity matched with the rotating speed of the fan. When the two fans are shielded to the same extent, the air inlet of the two fans is not matched with the rotating speed, namely the current air inlet is smaller than the default air inlet. The default air inlet is the air quantity matched with the current rotating speed when the air inlet of the fan is not shielded.

The electronic device adjusts the rotation speeds of the first fan and the second fan based on a second air volume difference between the current air volume and the default air volume. In the adjustment process, the first fan and the second fan can be adjusted based on the same rotation speed adjustment value, for example, the rotation speeds of the first fan and the second fan are simultaneously adjusted to ensure that the total air inlet quantity reaches the air quantity required by the current operation of the electronic equipment, so that the heat dissipation function of the electronic equipment is not weakened due to shielding of the air inlet, and the heat dissipation function of the whole machine is improved.

After the rotation speed of the fan is adjusted, if the air inlet of the fan is detected to be matched with the rotation speed at the current sampling time, that is, the fan is not shielded, the rotation speed of the fan can be adjusted to the rotation speed corresponding to the last sampling time or the rotation speed in the non-shielding state of the air inlet. If the current sampling moment detects that the air inlet of the fan is smaller than the air inlet adjusted at the last sampling moment, the rotating speed of the fan can be continuously increased, and the air inlet of the fan is increased; therefore, the shielding condition of the air inlet of the fan is preliminarily determined based on the air inlet of the fan, the dynamic adjustment of the rotating speed of the fan is further realized, and the heat dissipation function of the electronic equipment and the heat dissipation effect of the whole machine are ensured.

Example III

Referring to fig. 6, a flowchart of a specific implementation of a method for adjusting a rotational speed of a fan according to an embodiment of the present application is shown; according to the embodiment of the application, when the air inlet of the fan is blocked based on the air volume difference value, the process of dynamically adjusting the rotating speed of the fan is realized based on the working temperature and the blocking condition of each part. As shown in fig. 6, the method for adjusting the rotation speed of the fan may include the following steps:

s601, the electronic equipment acquires the first air inlet quantity of the first fan and the second air inlet quantity of the second fan.

S602, if a first air volume difference exists between the first air volume and the second air volume at the same initial rotation speed, the electronic equipment acquires a temperature value output by the temperature detection module.

S603, the electronic device adjusts the rotation speed of the second fan of the rotation speed of the first fan based on the first air volume difference value and the temperature value.

In some embodiments, when the electronic device detects that one or more fans are blocked through the air inlet, in order to ensure the service time of the electronic device, the temperature value of the temperature detection module can be obtained at the same time, so as to monitor the running states of all components of the electronic device, and further, the rotating speed of the fans is more accurately adjusted by combining the running states of all components.

The electronic device stores a maximum temperature threshold corresponding to an operation state and a heat dissipation coefficient corresponding to different fan speeds according to temperature change in the operation process of each component aiming at different modules; for example, when the current running temperature of the main board is 35 degrees and the corresponding heat dissipation coefficient is 2, the fan rotation speed corresponding to the heat dissipation coefficient may be 2000 rpm, and when the temperature rises to 45 degrees, the corresponding heat dissipation coefficient is matched to be 2.5, and the fan rotation speed corresponding to the heat dissipation coefficient may be 2800 rpm. If the current rotating speed of the fan does not meet the requirement of the working temperature or the air inlet of the fan is shielded to a certain extent, the rotating speed of the fan is further adjusted; correspondingly, if the air inlets of the fans are blocked, the rotating speeds of the fans are continuously adjusted based on the detected air quantity difference values, so that the air inlet quantity of each fan reaches or approaches to the air inlet quantity of the rotating speed corresponding to the heat dissipation coefficient, or the air inlet quantity of all fans reaches or approaches to the total air inlet quantity of the rotating speed corresponding to the heat dissipation coefficient.

By way of example, the modules of the electronic device may include a motherboard, a processor, a graphics card, and the like.

It should be noted that, in combination with the working temperatures of the components of the electronic device, further adjusting the rotation speed of the fan is only illustrated by way of example, and the adaptation degree of the numerical value in the specific adjustment process can be set correspondingly based on the configuration of the electronic device; the corresponding relation between the rotating speed and the temperature can be set based on other parameters, for example, the corresponding required air inlet quantity is set directly based on the working temperature of each component, and then the rotating speed of the fan is adjusted based on the required air inlet quantity; when the air inlet is shielded, the rotating speed of the fan is further adjusted based on the detected shielding degree so as to achieve the required air inlet quantity; therefore, the heat dissipation effect of the electronic equipment is ensured, the rotating speed of the fan can be adjusted more pertinently by combining the temperature value under the condition that the fan is shielded, and the heat dissipation effect of the electronic equipment is further optimized.

Example IV

Referring to fig. 7, a flowchart of a specific implementation of a method for adjusting a rotational speed of a fan according to an embodiment of the present application is shown; according to the embodiment of the application, when the air inlets of different fans are shielded to different degrees, the process of dynamically adjusting the rotating speed of the fans is realized based on the working temperature of each part and the shielding condition of each air inlet. As shown in fig. 7, the method for adjusting the rotation speed of the fan may include the following steps:

S701, the electronic equipment acquires the first air inlet quantity of the first fan and the second air inlet quantity of the second fan.

S702, if a first air volume difference exists between the first air volume and the second air volume at the same rotating speed, the first air volume of the first fan is not matched with the initial rotating speed or the second air volume of the second fan is not matched with the initial rotating speed, and then the temperature value output by the temperature detection module is obtained.

S703, the electronic device adjusts the rotation speed of the first fan and the rotation speed of the second fan based on the first air volume difference value and the temperature value.

In some embodiments, when the air inlet of the fans is not matched with the initial rotation speed and there is a difference between the air inlets corresponding to the two fans, it is indicated that the air inlets of the different fans may be blocked to different degrees; based on the air volume difference and the temperature value output by the temperature detection module, the rotating speed of each fan is further and more accurately adjusted.

For example, there is a certain degree of shielding between the first fan and the second fan, and the shielding degrees may be different, and based on the same implementation principle as the three phases of the embodiment, the rotation speeds of the first fan and the second fan may also be adjusted by combining the temperature values output by the temperature detection module.

Accordingly, a heat radiation coefficient or required air intake corresponding to the working temperature of each component of the electronic equipment is set, and the heat radiation coefficient or required air intake corresponds to the rotating speed of the fan respectively, so that the air intake matched with the working temperature of each component can be realized based on the rotating speed of the fan, and the heat radiation effect of the electronic equipment is ensured.

It should be noted that, because the electronic equipment can judge the difference of the degree of being sheltered from by the air intake of different fans based on the air volume difference, and then when detecting that there is shielding in the air intake of fan, can gather the operating temperature of each part simultaneously, adjusts the rotational speed of first fan and second fan based on air volume difference and temperature value.

In addition, different components in the electronic device correspond to different working temperatures, such as a processor, a main board, a display card and the like, temperature values of all the components can be respectively measured through a plurality of temperature sensors, the highest current working temperature is used as a reference for adjusting the rotating speed, and an average value of the working temperatures of all the components can be used as a reference for adjusting the rotating speed.

Based on the implementation manners of the third embodiment and the fourth embodiment, in some embodiments, the electronic device adjusts the rotation speed of the first fan and the rotation speed of the second fan based on the first air volume difference value and the temperature value, respectively, and may include:

the electronic equipment calculates a first temperature difference value between the temperature value and a preset first temperature threshold value; calculating a first adjusting value corresponding to the first fan and a second adjusting value corresponding to the second fan based on the first air volume difference value and the first temperature difference value; the rotation speed of the first fan is adjusted based on the first adjustment value, and the rotation speed of the second fan is adjusted based on the second adjustment value.

The first temperature threshold is an exemplary highest temperature threshold at which the electronic device may be in a normal operating state, for example, a total first temperature threshold is set to 78 degrees; corresponding first temperature thresholds can also be set corresponding to different components respectively, for example, the first temperature threshold corresponding to the processor can be set to 75 degrees, the first temperature threshold corresponding to the display card is 80 degrees, the first temperature threshold corresponding to the main board and the hard disk is 65 degrees, and the like.

For example, when the difference between the current temperature value and the maximum temperature threshold is larger, the current temperature is lower, and the rotation speed adjustment value can be determined based on the shielding degree of each fan and the temperature difference; the rotation speed adjusting value is further converted into the corresponding driving current, and the rotation speed is adjusted by adjusting the driving current of the fan.

For example, the electronic device may further store a mapping relationship between the current air volume difference value and the current air volume difference value, the current air temperature difference value and the current rotation speed adjustment value, and the electronic device may determine the rotation speed adjustment value corresponding to the current air volume difference value and the current rotation speed adjustment value by using a table look-up method.

Based on the above implementation, in some embodiments, after adjusting the rotational speed of the first fan and the rotational speed of the second fan based on the first air volume difference value and the temperature value, respectively, the method further includes:

acquiring the total air inlet quantity of the first fan and the second fan at the nth sampling moment and a first temperature value output by the temperature detection module; calculating a second temperature difference value between the first temperature value and a second temperature value output by the temperature detection module at the (n-1) th sampling moment; the rotational speeds of the first fan and the second fan are adjusted based on the total air intake at the nth sampling time and the second temperature difference.

In an exemplary process of continuous operation of the electronic device, the temperature detection module reports the temperature of the whole machine or the temperature of each component of the electronic device at fixed time, and the electronic device compares temperature values acquired at different sampling moments and monitors the change rate of the temperature values. Wherein n is an integer greater than or equal to 2.

The electronic device may also periodically obtain the total air intake and the temperature value of the fan, and periodically detect the running states of each component and the fan. By comparing the temperature values at different sampling moments with the air inlet quantity, the temperature change condition, such as the condition of too fast or slow temperature rise, can be judged; based on the temperature change condition and the total air quantity at the current nth sampling time, determining the total air quantity adapted to the temperature change condition, and respectively adjusting the rotating speeds of the first fan and the second fan based on the adapted total air quantity.

Based on the above implementation, in some embodiments, adjusting the rotational speeds of the first fan and the second fan based on the total air intake at the nth sampling time and the second temperature difference includes:

if the second temperature difference value is larger than the second temperature threshold value, the rotating speeds of the first fan and the second fan are adjusted so that the total air inlet quantity of the first fan and the second fan reaches the total required air inlet quantity corresponding to the first temperature value; and if the second temperature difference value is smaller than the second temperature threshold value, controlling the first fan and the second fan to keep the rotating speed corresponding to the total air inlet quantity at the nth sampling moment.

The electronic device is also provided with a temperature change threshold value corresponding to different running states (such as different clock frequencies or calculation forces) of the electronic device, namely a second temperature threshold value. The second temperature threshold value can be used for monitoring the temperature change condition of the electronic equipment in the continuous use process. Based on the temperature values obtained at different sampling moments, determining the temperature change rate of the electronic equipment, and when the temperature change is rapid, on the basis of the original air inlet quantity, increasing the rotating speed of the fan and improving the total air inlet quantity of the fan; the temperature is slowly increased or hardly changed in a period of time, and the rotating speed can be kept unchanged; or when the temperature is reduced, the corresponding fan rotating speed can be reduced.

Correspondingly, when the temperature change is faster, for example, the current total air inlet rate is increased at a first change rate, the first change rate of the current total air inlet rate and the temperature value is not adapted, and the total air inlet rate is increased by adjusting the rotating speed of the fan in order to reduce the first change rate of the temperature and slow down the temperature increase. The rotating speed of each fan can be respectively adjusted based on the shielding degree of the fans, namely the air quantity difference value, while the total air quantity is improved. When the temperature change is slow, for example, the current total air inlet rate is increased at a second change rate, the current total air inlet rate is matched with the second change rate of the temperature value, or the second change rate is in a change rate interval matched with the total air inlet rate, the fan can be controlled to keep the current rotating speed; or, based on the shielding degree of the fans, namely the air quantity difference value, the rotating speeds of the fans are respectively adjusted to adapt to the total air quantity of the second change rate corresponding to the temperature value.

By the method, the temperature difference of the current working temperature of the electronic equipment from the highest temperature threshold value and the air inlet difference of the two fans are monitored, and the rotating speed adjustment values corresponding to the fans are calculated respectively, so that the heat dissipation control effect is more reliable and accurate, and the service time of the electronic equipment for normal operation can be prolonged to the maximum extent; meanwhile, the rotating speed of the fan is flexibly adjusted, so that the heat dissipation treatment is more in line with the actual application scene, and a better heat dissipation effect is realized.

Example five

Referring to fig. 8, a flowchart of a specific implementation of a method for adjusting a rotational speed of a fan according to an embodiment of the present application is shown; according to the embodiment of the application, the realization process of reducing the calculation force of the electronic equipment and comprehensively adjusting the rotating speed of the fans is realized based on the air inlet volume difference, namely, the shielding conditions of different degrees possibly existing at the air inlets of different fans. As shown in fig. 8, the method for adjusting the rotation speed of the fan may include the following steps:

s801, the electronic device acquires a first air inlet of a first fan and a second air inlet of a second fan.

S802, if a first air volume difference exists between the first air volume and the second air volume at the same initial rotation speed, the clock frequency or the power supply voltage of the processor is adjusted based on the first air volume difference.

S803, the electronic device adjusts the rotation speeds of the first fan and the second fan based on the adjusted clock frequency or power supply voltage of the processor and the first air volume difference value.

In some embodiments, when it is determined that there is a shielding at the air inlet of the fan through the difference of the air inlet amounts, the calculation force of the electronic device can be reduced by adjusting the clock frequency or the power supply voltage of the processor, and then the rotation speed of the fan is further adjusted based on the adjusted calculation force and the air inlet amount difference.

For example, when the air volume difference value is detected, that is, when at least one fan is shielded, only the computing power of the electronic equipment can be adjusted, that is, the clock frequency or the power supply voltage of the processor is reduced, so that the power consumption is reduced, and the service life of the electronic equipment is ensured; the air inlet of each fan can be further adjusted based on the air volume difference value while the calculation force is reduced; therefore, the normal operation of the electronic equipment is ensured, the heat dissipation effect is ensured, the power consumption is reduced, and the service time of the electronic equipment is prolonged.

In some embodiments, if there is a first air volume difference between the first air volume and the second air volume, the electronic device adjusts a clock frequency or a supply voltage of the processor based on the first air volume difference, including:

For example, under the condition that the fans have the same rotating speed, the degree of the fan which is shielded can be preliminarily determined through the relation between the air quantity difference value of the air quantity of the two fans and the difference threshold value, and the clock frequency or the power supply voltage of the processor is adjusted based on the shielding degree; when the air quantity difference value is larger, the shielding degree of one fan is higher, and under the condition that the normal operation of the electronic equipment is ensured, the adjusted clock frequency or power supply voltage is relatively lower, so that the running state of the electronic equipment and the heat dissipation effect of the fan are balanced.

For example, if the first fan has a shielding condition, determining a degree of reducing the rotation speed of the first fan and a degree of increasing the rotation speed of the second fan based on the adjusted total calculation force, so as to realize a state of balanced operation and higher work matching of the rotation speed of the first fan and the electronic equipment.

In some embodiments, after the electronic device adjusts the rotational speed of the first fan and the rotational speed of the second fan based on the first air volume difference, respectively, the method further includes:

For example, when the operating state of the electronic device corresponds to the state that the fan is not blocked, that is, the rotational speed of the fan is matched with the air intake of the fan, the rotational speed of the fan may be restored to the default parameter of the original state, for example, the fan is adjusted to the operating state under the same rotational speed.

As shown in fig. 9, an architecture schematic diagram of an electronic device fan according to an embodiment of the present application is provided; the electronic device may include two or more heat sinks, a battery, a motherboard, and a temperature sensor. As shown in fig. 9, the two heat dissipation devices may be a fan 1 and a fan 2, respectively; corresponding air intake sensors, such as an air intake sensor 1 corresponding to a fan 1 and an air intake sensor 2 corresponding to a fan 2, are respectively arranged corresponding to the two heat dissipating devices. Correspondingly, the air inlet sensor can be arranged at the center of the heat radiating device and can be integrated on the heat radiating device.

It should be noted that, in the above embodiment, the fan rotation speed is adjusted based on the air intake of the fan, the fan is adjusted based on the temperature and the air intake, and the fan rotation speed is adjusted after the processor is reduced; in another possible implementation manner, the working temperature of each component detected by the temperature detection module can be directly obtained, so that the rotating speed of the corresponding fan is directly adjusted based on the working temperature, and the speed of temperature rise is reduced; or, based on the shielding condition of the temperature detection module or the air inlet of the fan, the running state of the processor is directly adjusted, the calculation force is reduced, the temperature rise speed is slowed down, and the service time is prolonged; or after the calculation force of the processor is reduced, if the temperature continues to rise, the air quantity rotation speed is adjusted, and the like; that is, the embodiments can be combined in a cross way to carry out comprehensive adjustment, and can also be independently adjusted. Therefore, the running state of the electronic equipment and the heat dissipation effect of the fan are better matched and balanced, and the service time of the electronic equipment is effectively prolonged.

According to the embodiment of the application, whether the fan is shielded or not can be judged based on the air inlet quantity, and the differential dispatching of the rotating speed of the fan is carried out under the condition that the shielding exists, so that the heat dissipation capacity of the whole machine is improved, and meanwhile, the power consumption of the whole machine is reduced.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
