Detailed Description
The present application will be described in further detail with reference to fig. 1 to 5.
When simultaneously controlling a plurality of fans, because the model and the aging degree of each fan are different, the fan rotation speed which can be achieved when the same control circuit parameters are also different, if the same control circuit parameters are used for simultaneously controlling the plurality of fans, the heat dissipation effect is poor due to the individual difference of the fans, therefore, the embodiment of the application provides a fan control method, and referring to fig. 1, the method comprises the following steps:
s1, acquiring rotation speed detection values of a plurality of fans under the condition of the same control circuit parameters.
Specifically, during fan control, fan control is generally performed by adjusting the control voltage or the control current of the control circuit, so that the control circuit parameter of this embodiment is the control voltage or the control current, and the same control voltage or the control current is applied to each fan in the test stage before starting control, and the fan rotation speed under the condition of the same control voltage or control current is detected as the rotation speed detection value. In the specific implementation process, the rotating speed of the fan can be detected by adopting a rotating speed sensor, and the rotating speed of the rotating object can be converted into an electric signal by the rotating speed sensor to be output.
S2, obtaining the control coefficient of each fan according to the rotation speed detection values of different fans and the control circuit parameters.
Specifically, the control coefficient of the fan can reflect the rotational speed that the fan can reach under different control circuit parameters, namely different control voltages or control currents, so that the control coefficient of each fan is obtained according to the rotational speed detection value and the control circuit parameters in the test stage. In a specific implementation, the larger the control coefficient, the larger the rotational speed that can be achieved with the same control circuit parameters.
S3, acquiring the current required heat dissipation power.
Specifically, because the requirements for heat dissipation are different in different use situations, the fan needs to be controlled according to the current required heat dissipation power.
S4, controlling a plurality of fans according to the required heat dissipation power and the control coefficient of each fan.
Specifically, since the required heat dissipation power and the control coefficient of each fan are different, the present embodiment commonly controls a plurality of fans according to the required heat dissipation power and the control coefficient of each fan. The fan control circuit is used for controlling the fan to be started and closed and adjusting the rotating speed, wherein the fan control circuit is turned on, the fan control circuit is turned off, and the fan control circuit parameters in the fan control circuit are adjusted to control the rotating speed, so that corresponding control signals are required to be generated according to the control coefficients of the fan when the fan control circuit is used for controlling the rotating speed to adjust the parameters of the control circuit in the fan control circuit.
The implementation principle of the embodiment of the application is as follows: the rotating speed detection values of all fans under the condition of the same control circuit parameters are obtained through testing, and the control coefficients of all fans are obtained according to different rotating speed detection values, so that all fans are uniformly controlled according to required radiating power, and different fans are controlled according to different control coefficients.
The control coefficient can reflect the corresponding relation between the fan rotation speed and the control circuit parameters, and can be different according to different fan models and different aging degrees, when in actual use, the control coefficient of each fan needs to be obtained according to the fan rotation speed and the control circuit parameters to realize more accurate fan control, therefore, referring to fig. 2, the specific steps of step S2 in this embodiment include:
S201, obtaining rotating speed samples and control circuit parameter samples of a plurality of groups of fans in a fan control database, and corresponding control coefficient samples.
Specifically, the fan control database can be experimental data of fans with different models and different ageing degrees, which are collected in an experimental stage.
S202, constructing a rotating speed sample, a control circuit parameter sample and a corresponding control coefficient sample of a plurality of groups of fans as a control coefficient prediction sample set.
Specifically, in order to ensure that the control coefficient prediction sample set can cover the prediction comprehensiveness of the fan control coefficient, the control coefficient prediction sample set needs to include a plurality of different control circuit parameters with different models and different ageing degrees and corresponding rotating speeds under the different control circuit parameters.
S203, constructing a neural network prediction model, and inputting a control coefficient prediction sample set into the neural network prediction model for training and testing to obtain the control coefficient prediction model.
Specifically, the neural network prediction model may use a cyclic neural network (Recurrent Neural Network, RNN) model, and when training and testing the neural network model, 70% of the rotation speed samples, the control circuit parameter samples, and the corresponding control coefficient samples in the control coefficient prediction sample set may be constructed as a training set, and 30% of the rotation speed samples, the control circuit parameter samples, and the corresponding control coefficient samples may be constructed as a testing set. Firstly, inputting a rotating speed sample of a training set, a control circuit parameter sample and a corresponding control coefficient sample into a neural network prediction model for training to obtain a control coefficient prediction model to be tested. Inputting a rotating speed sample and a control circuit parameter sample in a test set into a control coefficient prediction model to be tested to obtain control coefficient prediction results to be detected, comparing all the control coefficient prediction results to be detected obtained in the test set with corresponding control coefficient samples in the test set, obtaining the accuracy of the test set by calculating a loss function corresponding to the control coefficient prediction results to be detected and the control coefficient samples, if the accuracy accords with a standard, indicating that the training of the control coefficient prediction model is completed, and if the accuracy does not accord with the standard, continuing to use the sample set for iterative optimization until the accuracy of the test set reaches the standard, and obtaining the trained control coefficient prediction model.
S204, inputting the collected rotation speed detection values of different fans and the control circuit parameters into a control coefficient prediction model to obtain a prediction control coefficient of each fan.
Specifically, as the common control of a plurality of fans is involved, the rotation speed detection value and the control circuit parameter of each fan are input into a control coefficient prediction model, and the control coefficient of each fan can be obtained respectively.
The implementation principle of the embodiment of the application is as follows: the model is trained by constructing a control coefficient prediction model and using a control coefficient prediction sample set, so that the control coefficient predicted by each fan can be obtained through the model, the accuracy and the intelligence of the control coefficient prediction are increased, and each fan can be precisely controlled according to accuracy.
When controlling the fan, the most important reference factor is the required heat dissipation power, which is related to the actual value of the current temperature and the required temperature in different situations, so referring to fig. 3, the specific steps in step S3 of this embodiment include:
s301, presetting a first temperature threshold.
Specifically, the first temperature threshold is a heat dissipation target temperature, and the heat dissipation target temperature is different under different use situations, so that the first temperature threshold can be adjusted according to requirements.
S302, receiving the actual temperature value acquired by the temperature acquisition equipment.
Specifically, the temperature acquisition device can use a temperature sensor, and the temperature sensor can convert a temperature signal into an electric signal and upload the electric signal so as to monitor the current actual temperature value in real time.
S303, obtaining the current required heat dissipation power according to the difference value of the temperature actual value and the first temperature threshold value.
Specifically, the larger the difference between the actual temperature value and the first temperature threshold value is, the larger the cooling range is required, and the larger the required heat dissipation power is.
The implementation principle of the embodiment of the application is as follows: the current required heat radiation power can be timely adjusted by monitoring the actual temperature value in real time, so that the opening, closing, rotating speed adjusting and the like of the fan are timely controlled, and the timeliness and accuracy of fan control are ensured.
When controlling a plurality of fans, the number of fans to be turned on and the rotational speed of the turned-on fans need to be considered, and therefore, referring to fig. 4, step S4 of this embodiment specifically includes:
S401, obtaining the number of fans and the rotating speed of the fans which are required currently according to the heat dissipation power which is required currently.
Specifically, air heat dissipation power (W) =air flow rate (m/s) ×air density (kg/m cube) ×air specific heat capacity (J/kg·k) ×temperature difference (K), wherein air flow rate refers to the speed of air flow; air density refers to the mass density of air, i.e. mass per cubic meter; the specific heat capacity of air refers to the amount of heat absorbed or released by a unit mass of air when the unit temperature changes; the temperature difference is the temperature difference between the air before and after heat dissipation. The air flow rate can be regulated and controlled by changing the rotating speed of the fans, and under the condition of common control of multiple fans, the opening quantity of the fans can also influence the air flow rate, so that the current required quantity of the fans and the rotating speed of the fans are required to be obtained according to the current required radiating power.
S402, controlling corresponding fans to be started or stopped according to the number of the fans required currently.
Specifically, under the condition of common control of multiple fans, the energy consumption can be effectively saved on the premise of ensuring the heat dissipation effect by controlling the opening quantity of the fans.
S403, controlling the rotating speed of the fan to be started according to the current required rotating speed of the fan and the control coefficient of the fan.
Specifically, as the control coefficient of each fan is different, the control circuit parameters corresponding to each fan to be started, namely the control voltage or the control current, can be obtained through the required fan rotating speed and the control coefficients of different fans, and the fan is controlled according to the control voltage or the control current, so that the rotating speed of each fan can be accurately controlled.
The implementation principle of the embodiment of the application is as follows: when radiating in great space, because required heat dissipation power is different, when required heat dissipation power is low, need not to open all fans and dispel the heat, consequently obtain the quantity that the fan needs to open through required heat dissipation power, need not the fan of opening and can close the use to play the effect of saving the energy consumption. Meanwhile, the required fan rotating speed of each fan is obtained according to the required heat dissipation power, and the corresponding control circuit parameters of the fans are controlled and adjusted according to the fan rotating speed and the control coefficient of the fans, so that the rotating speed of each fan is adjusted in a targeted mode, and the accuracy of fan control is improved.
In another embodiment, a plurality of fans are required to be uniformly arranged in a space requiring heat dissipation, so that temperature sensors are also uniformly arranged in the space requiring heat dissipation, and the fans at different positions are controlled to be turned on, turned off and the rotating speed is regulated according to the actual temperature values acquired by the temperature sensors at the different positions, so that fan control is performed in a larger space more accurately, and the heat dissipation effect is enhanced.
In the process of controlling the heat dissipation of the fan, when the heat dissipation is not needed, the fan needs to be turned off in time to save energy consumption, so that the embodiment further comprises: presetting a second temperature threshold, wherein the second temperature threshold is smaller than the first temperature threshold; receiving a temperature actual value acquired by temperature acquisition equipment; and when the actual temperature value is smaller than the second temperature threshold value, controlling all fans to be turned off. The second temperature threshold is the minimum temperature required by heat dissipation, and when the actual temperature value is smaller than the second temperature threshold, the heat dissipation is not needed, and all fans are controlled to be turned off so as to achieve the effect of saving energy consumption.
In order to further ensure the reliability in the fan control process, a circuit detection device is also required to detect the abnormal condition of the fan control circuit in real time; and when the fan control circuit abnormal signal detected by the circuit detection equipment is received, all fans are controlled to be closed. In the implementation process, the circuit detection device can be a universal meter, an ammeter, an ohmmeter or the like.
Because the fan is mainly controlled by adjusting parameters of the control circuit, when the control circuit is abnormal, the fan is possibly damaged, so that the abnormal condition of the control circuit is required to be detected in real time through the circuit detection equipment, and when the control circuit is abnormal, the circuit detection equipment generates abnormal signals, so that all fans are controlled to be closed according to the abnormal signals, and the effects of protecting the fans and enhancing the reliability of the control circuit are achieved.
In order to further ensure the safety in the fan control process, an induction device is also required to sense people or other objects approaching the fan; and when a signal that an object approaches after the fan detected by the sensing equipment is started is received, the fan is controlled to be closed.
Because the fan rotates at a high speed, if someone or other objects are close, the fan may be damaged, and therefore the object close to the opened fan needs to be detected through the sensing device, and if the object is detected to be close, the fan is controlled to be closed, so that the safety in the fan control process is ensured. In the implementation process, the sensing device can adopt a proximity sensor, and the proximity sensor can detect that an object is close and convert the object into an electric signal to upload so as to control the fan to be turned off in time.
