[0084] Specifically, the above step S202 may include the following steps:

[0085] Step S2021, according to the user instruction, determining the target digital gear corresponding to the target motor corresponding to the user instruction.

[0086] Specifically, the target motor includes multiple physical gears, and the above step S2021 may include the following steps:

[0087] Step a1, according to the user instruction, determining the target physical gear position of the target motor corresponding to the user instruction.

[0088] Therein, the number of the target physical gear positions is at least one.

[0089] Specifically, the target motor may determine the target physical gear position in the target motor corresponding to the user command according to the corresponding relationship between the user command and each physical gear position in the target motor.

[0090] Step a2: determining a target digital gear position corresponding to the target physical gear position according to the relationship between each physical gear position and the digital gear position.

[0091] Specifically, the target motor determines the target digital gear position corresponding to the target physical gear position according to the relationship between each physical gear position and the digital gear position.

[0092] For example, there are n physical gears on the target motor interface (both high and low voltage inputs on the mainboard can activate the gears), and up to 2n-1 digital gears can be output according to different physical gear combinations. The target motor can determine the target digital gear corresponding to the target physical gear according to the relationship between each physical gear and the digital gear.

[0093] Step S2022, determining the target air volume value corresponding to the target digital gear position according to the corresponding relationship between the digital gear position and the air volume value.

[0094] Specifically, the target motor can search for the corresponding relationship between the digital gear and the air volume value in the storage device. Then, according to the corresponding relationship between the digital gear and the air volume value found, the target air volume value corresponding to the target digital gear is determined.

[0095] Step S203, controlling the rotation speed of the target motor according to the target air volume value so that the air volume of the target device reaches the target air volume value.

[0098] In this embodiment, a wind volume control method is provided, which can be used for the target motor in the above-mentioned target device. Figure 3 is a flow chart of the air volume control method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0099] Step S301, receiving user instructions.

[0100] The user instruction is used to indicate that the air volume of the target device is controlled to a target air volume value.

[0101] For details about this step, please refer to the above description of step S201, which will not be elaborated here.

[0102] Step S302: determining a target air volume value corresponding to the target device according to a user instruction.

[0103] For details about this step, please refer to the above description of step S202, which will not be elaborated here.

[0104] Step S303, according to the target air volume value, the rotation speed of the target motor is controlled so that the air volume of the target device reaches the target air volume value.

[0105] Specifically, the above step S303 may include the following steps:

[0106] Step S3031, obtaining a target load corresponding to the target motor.

[0107] The target load is the air outlet component in the target device.

[0108] Specifically, the target motor can detect the code values ​​of different power segments of the controller hardware, and then determine the target load corresponding to the target motor according to the code values ​​of the different power segments of the controller hardware.

[0109] Step S3032: determining a first corresponding relationship between the power and the air volume of the target motor corresponding to the target load according to the target load.

[0110] The first corresponding relationship is obtained by fitting the experimental power and the experimental air volume of the target motor under the target load.

[0111] Specifically, the target motor can search the storage device for a first corresponding relationship between the power and the air volume of the target motor corresponding to the target load according to the target load.

[0112] It should be noted that the storage device may store the first correspondence between the power and the air volume corresponding to various loads. The first correspondence between the power and the air volume corresponding to different loads is different.

[0113] Optionally, the first correspondence between power and air volume can be generated by fitting a series of working point data of air volume data and power data corresponding to each load collected in a laboratory for each load, wherein the number of working point data is at least 15.

[0114] Step S3033: Determine the target power value corresponding to the target air volume value according to the first corresponding relationship.

[0115] Specifically, the target motor can bring the target air volume value into the first corresponding relationship to calculate and obtain the target power value corresponding to the target air volume value.

[0116] Step S3034, controlling the speed of the target motor according to the target power value so that the air volume of the target device reaches the target air volume value.

[0117] Specifically, the above step S3034 may include the following steps:

[0118] Step b1, determining a second corresponding relationship between the rotation speed and power of the target motor corresponding to the target load according to the target load.

[0119] The second corresponding relationship is obtained based on the experimental speed and experimental power fitting of the target motor under the target load.

[0120] Specifically, the target motor may search the storage device for the second corresponding relationship between the rotation speed and power of the target motor corresponding to the target load according to the target load.

[0121] It should be noted that the storage device may store the second correspondence between the rotation speed and the power corresponding to various loads. The second correspondence between the rotation speed and the power corresponding to different loads is different.

[0122] Optionally, the second corresponding relationship between the rotation speed and the power can be generated by fitting a series of working point data corresponding to the power data and the rotation speed data of each load collected in the laboratory, wherein the number of working point data is at least 15.

[0123] Step b2, controlling the rotation speed of the target motor according to the target power value and the second corresponding relationship so that the air volume of the target device reaches the target air volume value.

[0124] Specifically, the above step b2 may include the following steps:

[0125] Step b21, adjust the speed of the target motor to obtain the current speed value.

[0126] Specifically, the target motor can adjust the rotation speed of the target motor, and monitor the rotation speed of the target motor to obtain the current rotation speed value.

[0127] Step b22: Determine the current power value corresponding to the current rotation speed according to the second corresponding relationship.

[0128] Specifically, the target motor can substitute the current speed value into the second corresponding relationship to calculate the current power value corresponding to the current speed.

[0129] Step b23, according to the relationship between the current power value and the target power value, the current speed value of the target motor is adjusted so that the air volume of the target device reaches the target air volume value.

[0130] Specifically, the above step b23 may include the following steps:

[0131] Step b231, calculating a first difference between the current power value and the target power value.

[0132] Specifically, the target motor may calculate a first difference between a current power value and a target power value.

[0133] Exemplarily, the target motor may calculate a first difference by subtracting a target power value from a current power value.

[0134] Step b232: If the first difference is within the preset difference range, it is determined that the air volume of the target device reaches the target air volume value.

[0135] Specifically, if the first difference is within the preset difference range, the target motor confirms that the current power value is the target power value, and thus determines that the air volume of the target device reaches the target air volume value.

[0136] Among them, the preset difference range can be received by the target motor as user input, or it can be received and sent by other devices, or it can be set according to the attribute information of the target motor. The embodiment of the present application does not specifically limit the way in which the target motor obtains the preset difference range.

[0137] Step b233: if the first difference is outside the preset difference range, the target speed value is calculated according to the target power value of the target motor.

[0138] Specifically, if the first difference is outside the preset difference range, then based on the first difference, the target motor calculates the target speed value according to the target power value.

[0139] Step b234, calculating the second difference between the target speed value and the current speed value.

[0140] Specifically, the target motor may calculate a second difference between the target rotation speed value and the current rotation speed value.

[0141] Step b235, adjusting the current speed value of the target motor according to the second difference so that the air volume of the target device reaches the target air volume value.

[0142] Specifically, the target motor can adjust the current rotation speed value of the target motor according to the second difference so that the air volume of the target device reaches the target air volume value.

[0143] For example, the target motor can obtain a second difference by subtracting the target speed value from the current speed value. If the second difference value is greater than 0, the target motor reduces the current speed value, and if the second difference value is less than 0, the target motor increases the current speed value.

[0144] The embodiment of the present application provides an air volume control method, which obtains a target load corresponding to a target motor; according to the target load, determines a first correspondence between the power of the target motor corresponding to the target load and the air volume, thereby ensuring that the determined first correspondence matches the target load, thereby ensuring the accuracy of the determined first correspondence. According to the first correspondence, determines a target power value corresponding to the target air volume value, thereby ensuring the accuracy of the determined target power value.

[0145] Then, according to the target load, a second corresponding relationship between the rotational speed and the power of the target motor corresponding to the target load is determined, thereby ensuring that the determined second corresponding relationship matches the target load and further ensuring the accuracy of the determined second corresponding relationship.

[0146] According to the target load, the second corresponding relationship between the speed and power of the target motor corresponding to the target load is determined, which ensures that the determined second corresponding relationship matches the target load, and further ensures the accuracy of the determined second corresponding relationship. The first difference between the current power value and the target power value is calculated to ensure the accuracy of the calculated first difference. If the first difference is within the preset difference range, it is determined that the air volume of the target device reaches the target air volume value; if the first difference is outside the preset difference range, the target speed value is calculated according to the target power value of the target motor, which ensures the accuracy of the calculated target speed value. The second difference between the target speed value and the current speed value is calculated to ensure the accuracy of the calculated second difference. According to the second difference, the current speed value of the target motor is adjusted so that the air volume of the target device reaches the target air volume value.

Among them, the relevant variables can represent the corresponding relationship between each digital gear and the target air volume; the function initialization can be the first corresponding relationship between the power and air volume of the target motor and the second corresponding relationship between the speed and power of the target motor. Among them, the PC can read and write the gear application parameters, and then store the gear application parameters in the digital gear application parameter storage module. The multi-physical gear detection module can detect the physical gear corresponding to the current target motor, and then determine the current digital gear based on the physical gear to digital gear conversion module. Then, the motor detects the effective gear and calls the corresponding stored gear parameter to output the target air volume value; the motor detects the different power segment code values ​​of the controller hardware and calls the corresponding constant air volume model coefficient; the air volume loop is closed-loop controlled based on the target air volume value and the constant air volume coefficient; the air volume loop outputs the target speed through the FOC vector control core SVPWM output. Then, it is driven based on the inverter drive module, and the air volume output is controlled based on the inverter output module. In addition, the actual speed of the output module is detected by detecting voltage, phase current, and speed, and the actual speed and motor status are fed back to the main board to form a closed loop.

[0148] For example, Figure 5The target motor includes a motor interface, a central control unit and a motor body. The motor interface includes multiple physical gears. There is a certain correspondence between the physical gear and the digital gear. A combination of n physical gears can output up to 2 n -1 digital gear. The motor interface includes a transmitting line and a receiving line for user instructions input by the user. Then, according to the user instruction, the physical gear included in the user instruction is confirmed, and the digital gear is determined according to the correspondence between the physical gear and the digital gear. The central control unit includes a gear parameter storage module for storing the correspondence between each digital gear and the target air volume. The central control unit also includes a constant air volume model parameter storage module for storing a first correspondence between the power and air volume of the target motor and a second correspondence between the speed and power of the target motor. The central control unit controls the output of six pulse width modulation signals based on the constant air volume closed-loop control module. Then, it is driven based on the inverter drive module, and the air volume output is controlled based on the inverter output module. In addition, the actual speed of the output module is detected by detecting the voltage, phase current, and speed, and the actual speed and motor status are fed back to the mainboard to form a closed loop.
