[0097] Embodiment one

[0098] Please refer to Figure 1 , Figure 1 It is a flow chart of the control method of the air outlet equipment disclosed in the embodiment of the application. Among them, Figure 1 The method described can be applied to the control device of air outlet equipment, the control device of air outlet equipment can be an independent device, can also be integrated in air outlet equipment, and the embodiment of the application is not limited. As Figure 1 The control method of the air outlet equipment can include the following operations:

[0099] 101, judge whether the target air volume corresponding to the fan of air outlet equipment meets preset demand air volume.

[0100] In the embodiment of the application, first judge whether the target air volume corresponding to the fan of air outlet equipment meets preset demand air volume, wherein, target air volume can be measured by air volume measuring instrument, can also be calculated by fan speed and static pressure value of air pipe, and the embodiment of the application is not limited.

[0101] Optionally, judge whether the target air volume corresponding to the fan of air outlet equipment meets preset demand air volume, including: judge whether the difference between target air volume and preset demand air volume is less than or equal to preset air volume threshold value; when the judgment result is no, it is determined that the target air volume corresponding to the fan of air outlet equipment does not meet preset demand air volume.

[0102] In the embodiment of the application, the absolute value of the difference between target air volume and preset demand air volume can be compared with the size of preset air volume threshold value to judge.

[0103] 102, when the judgment result is no, the target rotating speed of the fan is determined according to the reference parameter determined in advance and the preset required air volume, wherein the air volume of the air supply device at the target rotating speed meets the preset required air volume.

[0104] In the embodiment of the present application, when it is judged that the air volume of the air supply device cannot meet the preset required air volume, the target rotating speed of the fan at which the preset required air volume can be reached can be determined according to the reference parameter determined in advance and the preset required air volume. The reference parameter determined in advance includes the electrical parameter (PWM duty cycle, voltage value, current value, electromagnetic torque value, etc.) of the motor measured, the static pressure value of the air pipe, the dynamic pressure value of the air pipe outlet, etc., which are not limited in the embodiment of the present application.

[0105] 103, the current rotating speed of the fan is adjusted to the target rotating speed through a preset PID algorithm model.

[0106] In the embodiment of the present application, the PID algorithm model is a motor rotating speed adjustment model of the fan. Optionally, the PID algorithm model can include one or more combinations of proportional parameter, integral parameter and differential parameter, which are not limited in the embodiment of the present application. The real-time rotating speed of the fan is monitored, and the electrical parameter of the motor is dynamically adjusted, so that the rotating speed of the fan reaches the target rotating speed.

[0107] It can be seen that the method described in the embodiment of the present application can calculate the target rotating speed of the fan through the reference parameter determined in advance and the preset required air volume when the air volume does not meet the preset required air volume, improve the efficiency of intelligent adjustment of the rotating speed of the fan, and further ensure the constant air volume and improve the intelligent degree of the air supply device.

[0108] In an optional embodiment, before judging whether the air volume corresponding to the air supply device meets the preset required air volume, the method can further include the following operations:

[0109] The current rotating speed of the fan of the air supply device is detected, and the current rotating speed of the fan is adjusted to a preset standard static pressure rotating speed;

[0110] When the current rotating speed of the fan reaches the preset standard static pressure rotating speed, the static pressure value of the air pipe of the air supply device is calculated according to the current motor operating parameter corresponding to the fan, the current air volume of the fan at the preset standard static pressure rotating speed is determined as the target air volume corresponding to the fan according to the static pressure value of the air pipe, and the step of judging whether the target air volume corresponding to the fan of the air supply device meets the preset required air volume is triggered;

[0111] In the embodiment of the present application, before it is judged whether the air volume of the air supply device meets the preset required air volume, the actual air duct static pressure value corresponding to the current installation environment of the fan can also be determined by adjusting the current rotating speed of the fan to the state of the preset standard static pressure rotating speed. For example, the rotating speed value, static pressure value and motor operating parameter value corresponding to the preset standard static pressure rotating speed of the fan are measured before the fan is shipped, for example, the rotating speed is 100 r / min, the static pressure value is 10 Pa, and the motor PWM duty cycle is 10%. After the current rotating speed of the fan is adjusted to 100 r / min, the current motor operating parameter is measured to be 20%, and then the air duct static pressure value can be determined by a preset calculation formula, model or table lookup method, that is, the air duct static pressure value is 20 Pa. Further, the current air volume of the fan at the preset standard static pressure can be determined according to the calculated air duct static pressure value, and it is judged whether the preset required air volume is met.

[0112] It can be seen that the method described in the embodiment of the present application can provide a convenient way to determine the air duct static pressure value. By adjusting the fan to the preset standard static pressure rotating speed state in advance, monitoring and measuring the motor operating parameter, and calculating the air duct static pressure value corresponding to the air supply device, the target rotating speed is adjusted through the air duct static pressure value to realize the control of the air volume, thereby improving the efficiency and accuracy of determining the air duct static pressure value, and improving the user experience.

[0113] In another optional embodiment, the motor operating parameter includes any one of a PWM duty cycle, a voltage value, a current value, and an electromagnetic torque value.

[0114] In the embodiment of the present application, the method for determining the air duct static pressure value corresponding to the air supply device can include the following operations:

[0115] The current motor operating parameter corresponding to the fan is input into the static pressure calculation model associated with the preset standard static pressure rotating speed to obtain an output result of the static pressure calculation model, and the static pressure calculation model is used to represent the relationship between the static pressure value and the motor operating parameter of the air supply device in the state of the preset standard static pressure rotating speed.

[0116] The static pressure value included in the output result of the static pressure calculation model is determined as the air duct static pressure value of the air supply device.

[0117] In the embodiment of the present application, the monitored motor operating parameter is input into the pre-determined static pressure calculation model to obtain the output result including the static pressure value, wherein the static pressure calculation model should be associated with the preset standard static pressure rotating speed of the fan. It should be noted that the static pressure calculation model is used to represent the relationship between the static pressure value and the motor operating parameter of the air supply device in the state of the preset standard static pressure rotating speed.

[0118] It can be seen that the method described in the embodiment of the application can realize accurate calculation of the static pressure value through the motor operating parameter and the static pressure calculation model, which is beneficial to improve the calculation accuracy of the subsequent target rotating speed, and further improve the precision and accuracy of the final air volume control.

[0119] In another optional embodiment, determining the target rotating speed of the fan according to the predetermined reference parameter and the preset required air volume can include the following operations:

[0120] inputting the static pressure value of the air pipe of the air supply equipment into the rotating speed calculation model associated with the preset required air volume to obtain an output result of the rotating speed calculation model, the rotating speed calculation model being used to represent the relationship between the static pressure value and the rotating speed of the fan of the air supply equipment under the preset required air volume state;

[0121] determining the rotating speed of the fan included in the output result of the rotating speed calculation model as the target rotating speed of the fan.

[0122] In the embodiment of the application, after the static pressure value of the air pipe of the air supply equipment is determined, the static pressure value is input into the predetermined rotating speed calculation model to obtain an output result including the target rotating speed of the fan, wherein the rotating speed calculation model should be associated with the air volume of the fan. It should be noted that the rotating speed calculation model is used to represent the relationship between the static pressure value and the rotating speed of the fan of the air supply equipment under the target air volume state.

[0123] For example, the rotating speed calculation model represents the relationship between the static pressure value and the rotating speed under different air volume states. If the preset required air volume is 100 cubic meters per minute, and the calculated static pressure value of the air pipe is 20 Pa, then the rotating speed of the air pipe can be determined through the preset rotating speed calculation model (such as a calculation formula, a lookup table, etc.) to reach 200 r / min, and the air volume can meet the preset required air volume.

[0124] It can be seen that the method described in the embodiment of the application can realize accurate calculation of the target rotating speed through the preset required air volume and the rotating speed calculation model, and further improve the precision and accuracy of the final air volume control.

[0125] In another optional embodiment, before the static pressure value of the air pipe of the air supply equipment is calculated according to the current motor operating parameter corresponding to the fan, the method can further include the following operations:

[0126] determining a static pressure calculation model associated with the preset standard static pressure rotating speed;

[0127] The static pressure calculation model associated with the preset standard static pressure rotating speed is determined by:

[0128] maintaining the rotating speed of the fan of the air supply equipment at the preset standard static pressure rotating speed;

[0129] adjusting the motor operating parameter of the fan according to the preset parameter adjustment step, obtaining a motor operating parameter set, the motor operating parameter set comprising at least one to-be-fitted motor operating parameter;

[0130] when obtaining each to-be-fitted motor operating parameter, detecting the static pressure value of the fan under the to-be-fitted motor operating parameter;

[0131] according to a first interpolation fitting algorithm, fitting all first arrays in the first array set to obtain a first fitting curve between the static pressure value and the motor operating parameter, each first array comprising a to-be-fitted motor operating parameter and a static pressure value of the fan under the to-be-fitted motor operating parameter, and different first arrays comprising different to-be-fitted motor operating parameters;

[0132] determining the first fitting curve as the static pressure calculation model.

[0133] In the embodiment of the application, before calculating the air pipe static pressure value, the application can also obtain a static pressure calculation model associated with the preset standard static pressure speed through pre-adjustment. First, in the pre-adjustment process, the speed of the fan of the air outlet device needs to be kept unchanged at the preset standard static pressure speed, the motor operating parameter of the fan is adjusted in a step-by-step manner according to the preset parameter adjustment step, to obtain a motor operating parameter set comprising at least one to-be-fitted motor operating parameter, and the static pressure value of the fan under each to-be-fitted motor operating parameter is detected. For example, the preset standard static pressure speed is 100 r / min, the speed of the fan is adjusted to 100 r / min, at this time the PWM duty cycle of the motor is 10%, the PWM duty cycle of the motor is adjusted in a step of 5%, and the static pressure value of the fan is monitored, for example, the following set of to-be-fitted motor operating parameters and static pressure values (i.e., the above-mentioned first array set) can be obtained: {10%, 10 Pa}, {15%, 15 Pa}, {20%, 20 Pa}, {25%, 25 Pa}.

[0134] Further, according to the difference fitting algorithm (i.e., the above-mentioned first interpolation fitting algorithm), all first arrays in the first array set can be fitted to obtain a fitting curve (first fitting curve), and the fitting curve is determined as the static pressure calculation model. It should be noted that the first interpolation fitting algorithm can include a linear interpolation fitting algorithm, a spline interpolation fitting algorithm, a least square interpolation fitting algorithm, etc., and the embodiment of the application is not limited.

[0135] It can be seen that the method described in the embodiment of the application can provide a static pressure calculation model associated with a preset standard static pressure speed in a pre-adjustment manner, and the relationship between the motor operating parameter of the fan and the static pressure value is determined conveniently and quickly. The pre-adjustment manner is beneficial to reducing the difficulty of obtaining the static pressure calculation model, and the interpolation fitting manner is beneficial to improving the precision and accuracy of the static pressure calculation, and is beneficial to improving the accuracy of the subsequent calculation of the target speed of the fan, and further improving the precision and accuracy of the final air volume control.

[0143] determining the second fitting curve as the speed calculation model.

[0144] In the embodiment of the present application, before determining the target rotating speed of the fan, the rotating speed calculation model associated with the preset required air output can also be obtained by another pre-adjustment manner. First, in the pre-adjustment process, the air output of the fan of the air output device needs to be kept unchanged at the preset required air output, and the rotating speed of the fan is adjusted in a step-by-step manner according to the preset rotating speed adjustment step, so as to obtain a fan rotating speed set including at least one to-be-fitted fan rotating speed, and the static pressure value of the fan at each to-be-fitted fan rotating speed is detected. For example, the preset required air output is 100 cubic meters per minute, the air output of the fan is controlled at 100 cubic meters per minute, the rotating speed of the motor is adjusted in a step of 50 r / min, and the static pressure value of the fan is monitored. For example, the following to-be-fitted fan rotating speed and static pressure value set (also referred to as the second array set) can be obtained: {100 r / min, 10 Pa}, {150 r / min, 15 Pa}, {200 r / min, 20 Pa}, and {250 r / min, 25 Pa}.

[0145] Further, all the second arrays in the second array set can be fitted according to a difference fitting algorithm (i.e., the second interpolation fitting algorithm described above) to obtain a fitting curve (second fitting curve), and the fitting curve is determined as the rotating speed calculation model. It should be noted that the second interpolation fitting algorithm can also include a linear interpolation fitting algorithm, a spline interpolation fitting algorithm, a least square interpolation fitting algorithm, etc., and the embodiment of the present application is not limited thereto.

[0146] It can be seen that the method described in the embodiment of the present application can provide a pre-adjustment manner to obtain a rotating speed calculation model associated with a preset required air output, which is convenient and fast to determine the relationship between the rotating speed and the static pressure value of the fan. The pre-adjustment manner is beneficial to reduce the difficulty of obtaining the rotating speed calculation model, and the interpolation fitting manner is beneficial to improve the accuracy and precision of the rotating speed calculation, and is beneficial to improve the accuracy and precision of the final air output control.

[0148] Please refer to Figure 2 , Figure 2 is another flowchart of the control method of the air output device disclosed in the embodiment of the present application. In the embodiment of the present application, Figure 2 The method described in the embodiment of the present application can be applied to the control device of the air output device. The control device of the air output device can be a separate device or can be integrated in the air output device, and the embodiment of the present application is not limited thereto. As shown in Figure 2 The control method of the air output device can include the following operations:

[0149] 201, determining whether the target air output corresponding to the fan of the air output device meets the preset required air output.

[0150] 202. When the judgment result is negative, determine the target speed of the fan based on the pre-determined reference parameters and the preset required air volume.

[0151] 203. By using a preset PID algorithm model, adjust the current speed of the fan to the target speed.

[0152] 204. Determine whether the air outlet equipment meets the status update conditions.

[0153] In this embodiment of the invention, the conditions for the air outlet device to meet the status update include one or more combinations of the following: the total running time of the air outlet device exceeds a first preset time; the single running time of the air outlet device exceeds a second preset time; the change value of the motor operating parameters within a third preset time range exceeds a preset parameter change threshold; and the change value of the ambient temperature or ambient humidity of the air outlet device within a fourth preset time range exceeds a preset threshold.

[0154] 205. When it is determined that the air outlet equipment meets the status update conditions, the update speed of the fan is re-determined; the current speed of the fan is adjusted to the update speed through a preset PID algorithm model.

[0155] Optionally, re-determining the updated rotational speed of the fan may include the following operations:

[0156] Re-execute the process of adjusting the current speed of the fan to the preset standard static pressure speed; when the current speed of the fan reaches the preset standard static pressure speed, calculate the duct static pressure value of the air outlet equipment according to the current motor operating parameters corresponding to the fan, and determine the current air volume of the fan at the preset standard static pressure speed as the target air volume corresponding to the fan based on the duct static pressure value;

[0157] Determine whether the target air volume corresponding to the fan of the air outlet equipment meets the preset air volume requirement;

[0158] When the judgment result is negative, the step of determining the target speed of the fan based on the pre-determined reference parameters and the preset required air volume is used as the updated speed of the fan.

[0159] In this embodiment of the invention, when it is determined that the air outlet equipment meets the status update conditions, it indicates that the air outlet volume of the fan may no longer meet the preset air outlet volume requirement, and dynamic adjustment is required. The fan speed can be readjusted to the preset standard static pressure speed, and the updated fan speed can be re-determined using the method in Embodiment 1 to meet the preset air outlet volume requirement.

[0160] In this embodiment of the invention, for other descriptions of steps 201-203, please refer to the detailed description of steps 101-103 in Embodiment 1 respectively. This embodiment of the invention will not repeat them.

[0161] As can be seen, the method described in this embodiment of the invention can dynamically monitor the current environmental status of the fan through various indicators, thereby determining whether the air volume still meets the preset air volume requirements. When it is determined that the requirements are not met, the fan speed is dynamically adjusted to adapt to the current environment of the fan. This is beneficial to improving the reliability and applicability of the solution, accurately determining the status update conditions, improving the precision and accuracy of the final air volume control, and enhancing the user experience.

[0162] In an optional embodiment, after adjusting the current speed of the fan to a preset standard static pressure speed, and before calculating the static pressure value of the air outlet duct based on the current motor operating parameters of the fan, the method may further include the following operations:

[0163] Determine whether the current motor operating parameters of the fan exceed the preset parameter threshold;

[0164] When it is determined that the current motor operating parameters of the fan exceed the preset parameter threshold, the air outlet equipment is identified as being in a state of dirt blockage, and a warning message is output to prompt the cleaning of the air outlet equipment.

[0165] In this embodiment of the invention, under normal circumstances, the motor operating parameters of the fan will operate within a reasonable range. When the current motor operating parameters of the fan exceed a preset parameter threshold, it can be determined that the air outlet equipment is in a state of blockage, resulting in an increase in static pressure. For example, when the PWM duty cycle of the motor exceeds 50%, its static pressure will exceed a certain value, which indicates that the air outlet equipment is in a state of blockage.

[0166] As can be seen, the method described in this embodiment of the invention can calculate the static pressure value through the motor operating parameters. At the same time, it can automatically monitor whether the air outlet equipment is in a state of dirt blockage by checking whether the motor operating parameters exceed a preset threshold. This helps to improve the reliability and applicability of the solution, ensure a constant air volume, avoid fan overload in the state of dirt blockage, and improve the user experience.
