Detailed Description
The core of the invention is to provide a method for regulating and controlling the rotating speed of a fan and related components. When the temperature of the component in the current time period is in the temperature stable interval, the temperature of the component fluctuates around the temperature stable point, and the fan is controlled to keep the current rotating speed. The fan has the advantages that the fluctuation of the rotating speed of the fan can be avoided when the working condition of the component is stable and the temperature fluctuates near the temperature stable point, and the stability is higher.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for regulating a fan rotation speed according to the present invention, where the method includes:
s11: determining an average value of the temperature of the component in a current time period, wherein the current time period is a time period which is a preset time period ahead with the current time as a reference;
s12: and when the average value is in a preset temperature stable interval, controlling the fan to keep the current rotating speed, wherein the preset temperature stable interval comprises a temperature stable point of the fan.
When the fan dissipates heat for the component, the current time temperature, the last time temperature and the last time temperature of the component are calculated to obtain the variable of the rotating speed of the fan, and the rotating speed of the fan is adjusted according to the variable of the rotating speed of the fan. Because the temperature of the component still fluctuates near the temperature stable point under the constant working condition, the calculated variable of the fan rotating speed is changed all the time, so that the fan rotating speed fluctuates all the time, and the stability of the fan rotating speed is poor.
The average value of the temperatures of the components in the current time period is determined, and the approximate range of the temperatures in the current time period can be obtained through the average value. And determining a temperature stable interval according to the temperature stable point, judging that the temperature of the current component fluctuates near the temperature stable point when the average value is in the temperature stable interval, and controlling the fan to keep the current rotating speed at the moment so as to avoid the fluctuation of the rotating speed of the fan caused by the fluctuation of the temperature near the temperature stable point under the condition that the component is constant.
Specifically, a temperature stabilization interval is set according to a temperature stabilization point, wherein the temperature stabilization zone is [ SP-a, SP + b ], and SP is the temperature stabilization point; a and b are numbers greater than 0, and specific values are not limited herein.
The current time period is determined by the current time and a preset time period, the starting time of the current time period is the time when the current time is ahead of the preset time period, and the ending time is the current time.
Fig. 2 is a graph of the rotation speed of a fan and the temperature of a component in the prior art, and fig. 3 is a graph of the rotation speed of the fan and the temperature of the component provided by the present invention. Therefore, the method provided by the invention keeps the rotating speed of the fan unchanged when the temperature of the component is in the temperature stable region.
On the basis of the above-described embodiment:
as a preferred embodiment, determining the average value of the temperature of the component in the current time period further comprises:
when the average value is not in the preset temperature stable interval, determining the increment of the rotating speed of the fan;
when the increment of the rotating speed of the fan is larger than 0, assigning the increment of the rotating speed of the fan as a first numerical value, wherein the first numerical value is larger than 0;
when the increment of the rotating speed of the fan is smaller than 0, assigning the increment of the rotating speed of the fan as a second numerical value, wherein the second numerical value is smaller than 0;
adding the current rotating speed of the fan and the increment of the rotating speed of the fan to obtain the target rotating speed of the fan;
the fan speed is adjusted to the target speed.
The increment value of the rotation speed is not fixed in consideration of the fact that the increment of the rotation speed of the fan varies according to the temperature of the current period. The increment of the rotating speed of the fan is assigned to be a first numerical value when the increment of the rotating speed of the fan is larger than 0, and is assigned to be a second numerical value when the increment of the rotating speed of the fan is smaller than 0, wherein the first numerical value is larger than 0, and the second numerical value is smaller than 0. And adding the current rotating speed of the fan and the increment of the rotating speed of the fan after assignment to obtain the target rotating speed of the fan, and controlling the fan to rotate at the target rotating speed so that the fan is stably accelerated by a first numerical value or decelerated by a second numerical value. Increasing or decreasing the speed of the fan by a fixed amount can achieve a continuously high increase and decrease capability.
In addition, the absolute value of the first numerical value and the absolute value of the second numerical value are not limited herein.
As a preferred embodiment, determining an average value of the temperature of the component over the current time period comprises:
determining a first temperature, a second temperature and an Nth temperature of the component at N continuous moments in the current time period, wherein N is an integer not less than 2;
an average of the first temperature, the second temperature, and up to the nth temperature of the component is determined.
For convenience of acquisition, when acquiring the temperature of the current time period, the temperature of the current time period is characterized by acquiring the temperatures of N consecutive time instants. The temperature of not less than two moments is obtained, and the average value of the temperature of the current time period can be represented by the average value of the temperatures of the N moments.
By sampling the N moments, the average value of the temperatures of the N moments can represent the average value of the temperatures of the current time period, and sampling is facilitated.
As a preferred embodiment, when N is equal to 3, determining the increment of the rotation speed of the fan includes:
calculating the increment of the rotating speed of the fan according to the rotating speed increment relational expression, the temperature stable point, the first temperature, the second temperature and the third temperature;
the rotating speed increment relation is as follows:
△PW M＝kp*[T(k)-T(k-1)]+ki*[T(k)-SP]+kd*[T(k)-2*T(k-1)+T(k-2)]；
kp, ki and kd are respectively a proportionality coefficient, an integral coefficient and a differential coefficient, SP is a temperature stable point, T (k-2) is a first temperature, T (k-1) is a second temperature, and T (k) is a third temperature.
And when k is the current moment, k-1 is the last moment, and k-2 is the last moment. When N is equal to 3, the increment of the rotation speed of the fan may be calculated by the PID formula according to the values of the three temperatures, the values according to the section setting, and the temperature stabilization point. Wherein kp, ki and kd are three values preset according to the component and are not changed after the component starts to work.
The temperature at three consecutive moments is calculated, and the change of the temperature is predicted in advance to obtain the increment of the fan.
As a preferred embodiment, after the average value is in the preset temperature stable interval, before controlling the fan to maintain the current rotation speed, the method further includes:
judging whether the average values of M time periods before the current time period are all in a preset temperature stable interval or not;
if yes, the step of controlling the fan to keep the current rotating speed is carried out.
The rotation speed of the fan is controlled to be kept unchanged when the average value is in the temperature stable interval. However, the temperature of the component is in a trend of continuously increasing, the temperature may be too high in the next time period, and the rotation speed of the fan cannot perform good heat dissipation on the temperature, which may damage the component.
Specifically, if the temperature stability interval is [78, 82], the temperature stability point is 80. The first temperature, the second temperature and the third temperature in the current time period are respectively 80, 82 and 84, and the average value of the temperatures in the current time period is 82, which is still in the temperature stability interval. However, the temperature tends to rise, and if the fan is not controlled to increase the speed, the temperature in the next time period is too high, which may damage the components. Therefore, a step of determining that the temperature of the component is currently in a state of fluctuating around the temperature stabilization point when the average value is in the temperature stabilization interval in M time periods before the current time period is added after the average value is in the temperature stabilization interval, and the rotation speed of the control fan is not changed.
The temperature can be reduced to be in a rising stage by adding a judging step, but the average value of the temperature is in a temperature stable interval, so that the rotating speed of the fan is not changed, and the fan can better radiate the components.
As a preferred embodiment, if the average value of M time periods before the current time period is not in the preset temperature stable interval, the method further includes:
determining an increase in the rotational speed of the fan;
when the increment of the rotating speed of the fan is larger than 0, assigning the increment of the rotating speed of the fan as a first numerical value, wherein the first numerical value is larger than 0;
when the increment of the rotating speed of the fan is smaller than 0, assigning the increment of the rotating speed of the fan as a second numerical value, wherein the second numerical value is smaller than 0;
adding the current rotating speed of the fan and the increment of the rotating speed of the fan to obtain the target rotating speed of the fan;
the fan speed is adjusted to the target speed.
When the average value of M time periods before the current time period is not in the preset temperature stable interval, the increment of the rotating speed of the fan and the target rotating speed of the fan are calculated by the method, and the fan is controlled to rotate at the target rotating speed.
