The heat conducting device may be a device which generates heat in the operation process of the electronic equipment, or a device which does not generate heat but generates temperature change due to heat conduction in the operation process of the electronic equipment.

The number of the heat conducting devices may be 3, 5, 8, or other numbers, and the application is not particularly limited, and the number of the temperature sensors is also not particularly limited. One temperature sensor corresponds to one heat conduction device, that is, one temperature sensor acquires the temperature of one heat conduction device.

Next, a description is given of a concept related to a gear of the heat dissipation device, where a parameter corresponding to the gear of the heat dissipation device may be an operating power of the heat dissipation device, the higher the gear is, the higher the corresponding operating power is, the parameter corresponding to the gear of the heat dissipation device may also be a rotation speed of the heat dissipation device, the higher the gear is, the higher the corresponding rotation speed is, and the like, and the parameter corresponding to the gear of the heat dissipation device is not specifically limited. It can be understood that the higher the gear of the heat dissipation device is, the better the heat dissipation effect is.

Wherein the heat sink includes, but is not limited to, a fan.

TABLE 1

In specific implementation, the presenting manner of the gear is not specifically limited, the highest gear may be gear 1, the higher the gear is, the smaller the corresponding number is, refer to table 1, and the lowest gear may be gear 1, and the higher the gear is, the larger the corresponding number is.

Further, the electronic device determining at least one reference gear based on the current gear and the at least one temperature includes the electronic device performing the following for each of the at least one temperature: if the current gear of the heat dissipation device is n gear, judging whether the current processing temperature is greater than or equal to a first reference temperature of n +1 gear, wherein n is a positive integer less than or equal to m; if the current processing temperature is lower than the first reference temperature of the n +1 gear, judging whether the current processing temperature is lower than a second reference temperature of the n gear; and if the current processing temperature is greater than or equal to the second reference temperature of the n gear, determining that the reference gear corresponding to the current processing temperature is the n gear.

For example, the gear of the electronic device and the first reference temperature and the second reference temperature corresponding to each gear are as shown in table 1, the current gear of the heat dissipation apparatus is 3 gears, only one temperature sensor is provided in the electronic device, the temperature of one heat conduction device obtained by the temperature sensor is 51 ℃, after it is determined that 51 ℃ is lower than the first reference temperature 60 ℃ of 4 gears, it is determined that 51 ℃ is higher than the second reference temperature 50 ℃ of 3 gears, and finally, it is determined that the reference gear corresponding to 51 ℃ of the heat conduction device is 3 gears.

Therefore, in the example, the electronic device can enable the temperature fluctuation of a single heat conduction device to be a wider control range, and the original gear is used as a reference gear, so that the heat dissipation device can not be frequently shifted due to the temperature fluctuation, the service life of the heat dissipation device is prolonged, and the noise is reduced.

Optionally, if the current gear of the heat dissipation device is n gear, after determining whether the currently processed temperature is greater than or equal to the first reference temperature of n +1 gear, the method further includes: and if the current processing temperature is greater than or equal to the first reference temperature of the n +1 gear, determining that the reference gear corresponding to the current processing temperature is the n +1 gear.

For example, the gear of the electronic device and the first reference temperature and the second reference temperature corresponding to each gear are as shown in table 1, the current gear of the heat dissipation apparatus is 3 gears, the electronic device is provided with a plurality of temperature sensors, one of the temperature sensors obtains the temperature of one heat conduction device as 60 ℃, and after it is determined that 60 ℃ is equal to the first reference temperature 60 ℃ of 4 gears, the reference gear corresponding to the temperature 60 ℃ of the heat conduction device is determined as 4 gears.

Therefore, in this example, the electronic device can increase the reference gear corresponding to the heat conducting device only when the temperature of the single heat conducting device rises to a higher temperature, so as to finally achieve that the heat dissipation device does not shift frequently due to temperature fluctuation, improve the service life of the heat dissipation device, and reduce noise.

Optionally, if the current gear of the heat dissipation device is n gear, after determining whether the currently processed temperature is greater than or equal to the first reference temperature of n +1 gear, the method further includes: if the current processing temperature is greater than or equal to the first reference temperature of the n +1 gear, judging whether the current processing temperature is greater than or equal to the first reference temperature of the n +2 gear; and if the current processing temperature is lower than the first reference temperature of the n +2 gear, determining that the reference gear corresponding to the current processing temperature is the n +1 gear.

For example, the gear of the electronic device and the first reference temperature and the second reference temperature corresponding to each gear are as shown in table 1, the current gear of the heat dissipation apparatus is 2 gears, a plurality of temperature sensors are provided in the electronic device, wherein one temperature sensor obtains a temperature of one heat conduction device of 57 ℃, after it is determined that 57 ℃ is greater than 55 ℃ of the first reference temperature of 3 gears, and after it is further determined that 57 ℃ is less than 60 ℃ of the first reference temperature of 4 gears, it is finally determined that the reference gear corresponding to 57 ℃ of the heat conduction device is 3 gears.

Further, after determining whether the currently processed temperature is greater than or equal to the first reference temperature of the n +2 gear if the currently processed temperature is greater than or equal to the first reference temperature of the n +1 gear, the method further includes: if the current processing temperature is greater than or equal to the first reference temperature of the n +2 gear, judging whether the current processing temperature is greater than or equal to the first reference temperature of the n +3 gear; and if the current processing temperature is lower than the first reference temperature of the n +3 gear, determining that the reference gear corresponding to the current processing temperature is the n +2 gear.

For example, the gear of the electronic device and the first reference temperature and the second reference temperature corresponding to each gear are as shown in table 1, the current gear of the heat dissipation apparatus is 2 gears, the electronic device is provided with a plurality of temperature sensors, one of the temperature sensors obtains a temperature of one heat conduction device of 64 ℃, after it is determined that 64 ℃ is greater than 55 ℃ of the first reference temperature of 3 gears, it is further determined that 64 ℃ is greater than 60 ℃ of the first reference temperature of 4 gears, and it is further determined that 64 ℃ is less than 65 ℃ of the first reference temperature of 5 gears, and the reference gear corresponding to the temperature of 64 ℃ of the heat conduction device is determined to be 4 gears.

It can be understood that, after determining that the current temperature is greater than the first reference temperature of the gear higher than the current gear by one gear, the electronic device may continue to determine the current temperature and the first reference temperature of the higher gear, when determining that the current temperature is greater than the first reference temperature of the higher gear, the electronic device may continue to determine the current temperature and the first reference temperature of the next higher gear, and so on, and the determining step is executed in a loop until determining that the reference gear corresponding to the current temperature is the highest gear when determining that the current temperature is greater than or equal to the first reference temperature of the highest gear.

It can be seen that in this example, the electronic device can increase to the matched reference gear when the temperature of the single heat conducting device rises to a higher temperature, so as to finally realize that the heat dissipation device does not shift frequently due to temperature fluctuation, improve the service life of the heat dissipation device, reduce noise, and save energy without damaging the heat conducting device.

Optionally, after determining whether the currently processed temperature is lower than a second reference temperature of the n gear if the currently processed temperature is lower than a first reference temperature of the n +1 gear, the method further includes: and if the current processing temperature is lower than the second reference temperature of the n gear, determining that the reference gear corresponding to the current processing temperature is the n-1 gear.

For example, the gear of the electronic device and the first reference temperature and the second reference temperature corresponding to each gear are as shown in table 1, the current gear of the heat dissipation apparatus is 3 gears, a plurality of temperature sensors are provided in the electronic device, one temperature sensor obtains the temperature of one heat conduction device as 48 ℃, after the temperature of 48 ℃ is judged to be lower than the first reference temperature of 4 gears 60 ℃, the temperature of 48 ℃ is judged to be lower than the second reference temperature of 3 gears 50 ℃, and the reference gear corresponding to the temperature of 48 ℃ of the heat conduction device is determined to be 2 gears.

Therefore, in this example, the electronic device can reduce the reference gear corresponding to the heat conducting device when the temperature of the single heat conducting device is reduced to a lower temperature, so that the finally determined gear of the heat dissipation device can ensure that the temperature of the system is not too high.

Optionally, after determining whether the currently processed temperature is lower than a second reference temperature of the n gear if the currently processed temperature is lower than a first reference temperature of the n +1 gear, the method further includes: if the current processing temperature is lower than the second reference temperature of the n grade, judging whether the current processing temperature is lower than the second reference temperature of the n-1 grade; and if the current processing temperature is greater than or equal to the second reference temperature of the n-1 gear, determining that the reference gear corresponding to the current processing temperature is the n-1 gear.

For example, the gear of the electronic device and the first reference temperature and the second reference temperature corresponding to each gear are as shown in table 1, the current gear of the heat dissipation apparatus is 3 gears, a plurality of temperature sensors are provided in the electronic device, wherein one temperature sensor obtains a temperature of one heat conduction device of 45 ℃, after the 45 ℃ is judged to be less than 60 ℃ of the first reference temperature of 4 gears, and further under the condition that the 45 ℃ is judged to be less than 50 ℃ of the second reference temperature of 3 gears, the 45 ℃ is judged to be greater than 40 ℃ of the second reference temperature of 2 gears, and then the reference gear corresponding to the 45 ℃ temperature of the heat conduction device is determined to be 2 gears.

Further, after determining whether the currently processed temperature is lower than the second reference temperature of the n-1 gear if the currently processed temperature is lower than the second reference temperature of the n-gear, the method further includes: if the current processing temperature is lower than the second reference temperature of the n-1 gear, judging whether the current processing temperature is lower than the second reference temperature of the n-2 gear; and if the current processing temperature is greater than or equal to the second reference temperature of the n-2 gear, determining that the reference gear corresponding to the current processing temperature is the n-2 gear.

For example, the gear of the electronic device and the first reference temperature and the second reference temperature corresponding to each gear are as shown in table 1, the current gear of the heat dissipation device is 4 gears, a temperature sensor is disposed in the electronic device, the temperature of a heat conduction device obtained by the temperature sensor is 42 ℃, after the 42 ℃ is judged to be less than the first reference temperature 65 ℃ of 5 gears, the 42 ℃ is judged to be less than the second reference temperature 58 ℃ of 4 gears, the 42 ℃ is further judged to be less than the second reference temperature 50 ℃ of 3 gears, finally the 42 ℃ is judged to be greater than the second reference temperature 40 ℃ of 2 gears, and the reference gear corresponding to the temperature 42 ℃ of the heat conduction device is determined to be 2 gears.

It can be understood that, after determining that the current temperature is less than the second reference temperature of the gear lower than the current gear by one gear, the electronic device may continue to determine the current temperature and the second reference temperature of the gear lower than the current gear, and when determining that the current temperature is less than the second reference temperature of the gear lower than the current gear, the electronic device may continue to determine the current temperature and the second reference temperature of the gear lower than the current temperature by one gear, and so on, and the determining step is executed in a loop until determining that the current temperature is less than the second reference temperature of the gear lower than the second reference temperature, and it is determined that the reference gear corresponding to the current temperature is the lowest gear.

It can be seen that, in this example, the electronic device can be lowered to the matched reference gear only when the temperature of the single heat conducting device is lowered to a lower temperature, so as to finally achieve that the heat dissipation device does not shift frequently due to temperature fluctuation, improve the service life of the heat dissipation device, reduce noise, and simultaneously achieve energy conservation without damaging the heat conducting device.

S204, the electronic equipment determines a target gear with the highest gear in the at least one reference gear.

It is to be understood that when the at least one reference gear is a reference gear, the reference gear is the target gear.

S205, the electronic equipment adjusts the working gear of the heat dissipation device according to the target gear and the current gear.

The implementation manner of adjusting the working gear of the heat dissipation device by the electronic device according to the target gear and the current gear may be: the electronic device compares the target gear with the current gear; if the target gear is different from the current gear, the electronic equipment generates a first control instruction according to the target gear so as to control the heat dissipation device to adjust the current gear to the target gear.

For example, if the electronic device has 5 gears, which are respectively 1 gear, 2 gear, 3 gear and 4 gear from low to high, if the target gear is 2 gear and the current gear is 3 gear, the electronic device generates a first control instruction according to the 3 gear to control the heat dissipation device to adjust the current gear to the target gear 2 gear.

In the specific implementation, if the electronic device is a projector, the projector includes four temperature sensors and a heating device green LED lamp, a red LED lamp, a blue LED lamp, a resistor and a heat dissipation device, which are respectively monitored by the four temperature sensors, when a heat dissipation device control program of the green LED lamp outputs the heat dissipation device in 3 steps, a heat dissipation device control program of the red LED lamp outputs the heat dissipation device in 4 steps, a heat dissipation device control program of the blue LED lamp outputs the heat dissipation device in 5 steps, and a heat dissipation device control program of the resistor outputs the heat dissipation device in 4 steps, the control program of the heat dissipation device outputs the heat dissipation device in 5 steps, so that the temperature of the heat conduction device is ensured to meet the requirements to the maximum extent.

In a specific embodiment, if the electronic device is a projector, the projector includes a temperature sensor, a red LED lamp as a heat generating device monitored by the temperature sensor, and a heat dissipation device, and the gears of the heat dissipation device and the first reference temperature and the second reference temperature corresponding to each gear are shown in table 1. When the optical machine is lighted, the monitoring temperature of the red LED lamp is 46 ℃, the operation gear of the heat dissipation device is 2, as the operating time of the light engine in the projector increases during the operation of the projector, the temperature of the red LED lamp slowly rises, when the temperature is higher than the second reference temperature of 50 ℃ of 3 grades, the heat dissipation device is still maintained at 2 grades, when the temperature is more than 55 ℃ of the first reference temperature of 3 grades, the heat dissipation device is adjusted to 3 grades, when the internal system of the electronic equipment slowly reaches a steady state, when the temperature of the red LED lamp fluctuates around the first reference temperature of 55 ℃ of 3 grades, the heat dissipation device can firstly increase the grade to 3 grades, then the temperature of the red LED lamp is slowly reduced, the temperature is maintained to fluctuate near 51 ℃, the temperature is not reduced to be below 50 ℃ of the second reference temperature of 3 grades, and the heat dissipation device is always in 3 grades, so that the heat dissipation device is prevented from being frequently shifted due to small-range fluctuation of the temperature.

In one possible example, before the electronic device obtains at least one temperature of the at least one heat conducting device through the at least one temperature sensor, the method further comprises: when the electronic equipment detects that the electronic equipment is started, a second control instruction is generated to control the heat dissipation device to be started, and the working gear is a preset gear.

The preset gear may be a highest gear among the gears of the heat dissipation device, and is not particularly limited.
