[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0043] The specific implementation of the present application is described in detail below in combination with specific embodiments:

[0044] Example One:

[0045] Figure 1 The implementation flow of the temperature control method based on high-speed air duct air temperature detection provided by the embodiment one of the present application is shown, only the part related to the embodiment of the present application is shown for convenience of description, and the details are as follows:

[0046] The method comprises the following steps S1 to S5:

[0047] S1: sequentially marking a heat point, a first temperature collection point, a second temperature collection point and an air outlet temperature collection point in the high-speed air duct;

[0048] Specifically, in step S1, as shown in Figure 9 , the air outlet temperature collection point 4 is located at the air outlet of the high-speed air duct 10;

[0049] In step S1, the first temperature collection point 2 is at a first distance from the heat source 1, the second temperature collection point 3 is at a second distance from the heat source 1, and the air outlet temperature collection point 4 is at a third distance from the heat source 1.

[0050] In step S1, the heat source is provided with a heating device, which is usually a heating wire.

[0051] In step S1, the temperature at the corresponding temperature collection point in the high-speed air duct is collected by a temperature sensor, such as a first temperature sensor at the first temperature collection point, a second temperature sensor at the second temperature collection point, and a third temperature sensor at the air outlet temperature collection point. In this embodiment, the first temperature sensor, the second temperature sensor, and the third temperature sensor are all NTC thermistor sensors.

[0052] S2: Mark a standard air temperature test point outside the high-speed air duct in a direction away from the air outlet temperature collection point;

[0053] Specifically, as shown in Figure 9 , the first air temperature test point 20 is at a fourth distance from the heat source 1.

[0054] In step S2, the standard air temperature test point is located outside the high-speed air duct and opposite the air outlet of the high-speed air duct, and is used to simulate the air temperature data at this position when there is an air duct.

[0055] S3: Obtain the first temperature data collected at the first temperature collection point, the second temperature data collected at the second temperature collection point, and the air outlet temperature data collected at the air outlet temperature collection point;

[0056] Specifically, in step S2, when the high-speed air duct starts to operate and the motor rotates, the heating device generates heat: the temperature of the air passing through the first temperature collection point is collected by the first temperature sensor, i.e. the first temperature data; the temperature of the air passing through the second temperature collection point is collected by the second temperature sensor, i.e. the second temperature data; the temperature of the air passing through the air outlet temperature collection point is collected by the third temperature sensor, i.e. the air outlet temperature data. Then, three sets of corresponding air temperature collection data are obtained, which are convenient for subsequent analysis and calculation of the three sets of air temperature collection data to calculate the temperature of the air passing through the standard air temperature test point.

[0057] S4: Calculate the standard air temperature data of the standard air temperature test point according to the first temperature data, the second temperature data, and the air outlet temperature data;

[0058] Specifically, as shown in Figure 2 , step S4 further includes steps S41 to S42:

[0059] S41: Based on the first distance and first temperature data, the second distance and second temperature data, and the third distance and outlet air temperature data, a wind temperature calculation model is obtained;

[0060] S42: Substitute the fourth distance into the wind temperature calculation model to calculate the standard wind temperature data.

[0061] In steps S41 and S42, for example, the first distance, the second distance, the third distance, and the fourth distance are set as X1, X2, X3, X4, X5, X6, X7, X8, X9, X1, X2, X3, X4 ...4, X5, X6, X7 n The first temperature data, the second temperature data, the outlet air temperature data, and the standard air temperature data are respectively set as Y1, Y2, Y3, and Y4. n Among them, X1, X2, X3, X n Y1, Y2, and Y3 have all been identified, Y n The value to be calculated;

[0062] Correspondingly, X1 and Y1 are a set of known data, X2 and Y2 are a set of known data, and X3 and Y3 are a set of known data. Substitute these three sets of known data into the following formula (1):

[0063] Y=aX 2 +bX+c(1)

[0064] Where a, b, and c are all constants;

[0065] The values ​​of a, b, and c are calculated from the above three sets of data. Then, the calculated values ​​of a, b, and c are substituted into formula (1) to obtain the formula for the wind temperature calculation model. Finally, X is substituted into the formula. n The value of X n Given that, Y can be calculated. n The value;

[0066] Then X1, X2, X3, X n and Y1, Y2, Y3, Y n Perform data fitting to obtain the fitted curve, such as Figure 8 As shown.

[0067] S5: Control the heating power and motor speed of the high-speed air duct according to standard air temperature data;

[0068] In step S5, after obtaining the standard air temperature data, it is determined whether the standard air temperature data meets the preset air temperature data. If it does, the air temperature is normal, and the motor speed and the heating power of the heating device do not need to be adjusted. Otherwise, if it does not meet the preset air temperature data, the air temperature is abnormal, and the motor speed and the heating power of the heating device need to be adjusted until the measured standard air temperature data meets the preset air temperature data. The preset air temperature data can be set in advance according to the actual application and usage requirements.

[0069] Since X1, X2, X3 are set inside the air duct, X n are set outside the air duct, Y n is actually the data at this position when there is an air duct; when Y n After the position of the air duct is deleted, a coefficient needs to be calibrated;

[0070] Based on this, after the standard wind temperature data is calculated, the method of the embodiment further includes:

[0071] S43: Calibrating the standard wind temperature data to obtain calibrated wind temperature data, and controlling the heating power and motor speed of the high-speed air duct according to the calibrated wind temperature data;

[0072] Specifically, as shown in Figure 3 and Figure 4 , in step S43, further includes steps:

[0073] S431: Setting a standard ambient temperature; wherein the standard ambient temperature is set to 23℃;

[0074] S432: Obtaining air inlet temperature data; wherein the air inlet temperature data is real-time ambient temperature data;

[0075] S433: Obtaining the motor speed of the high-speed air duct; wherein the range of the motor speed when the motor is running is generally set to 85000-100000 revolutions;

[0076] S434: Calculating calibrated wind temperature data according to the standard ambient temperature, air inlet temperature data, motor speed, and standard wind temperature data.

[0077] As shown in Figure 5 , in step S432, obtaining air inlet temperature data includes steps:

[0078] S4321: Marking an air inlet temperature collection point inside the air duct of the high-speed air duct; wherein, as shown in Figure 9 , the air inlet temperature collection point 5 is located at the air inlet of the high-speed air duct 10; the air inlet temperature collection point 5 is provided with a fourth temperature sensor, which is also an NTC thermistor sensor;

[0079] S4322: Obtaining ambient temperature data collected at the air inlet temperature collection point.

[0080] For example, the standard ambient temperature is set to 23℃, the air inlet temperature data is set to T a , and the motor speed is set to n, wherein T a and n are known, T a and n are taken as coefficients to obtain formula (2) of the following second wind temperature calculation model:

[0081] Y m=Y n -(n-90000) / 5000-10+(T a -23) (2) ;

[0082] The standard wind temperature data Y n calculated in step S4 is substituted into the above formula (2) to obtain the calibration wind temperature data Y m , so that the result is more accurate, and it is beneficial to more accurately control the motor speed and the heating power of the heating device in the high-speed air duct through the calibration wind temperature data Y m to achieve the purpose of precise temperature control.
