[0104] Step S303: Control the speed of the target motor according to the target air volume value so that the air volume of the target equipment reaches the target air volume value.

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

[0106] Step S3031: Obtain the 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 based on the code values ​​of different power segments of the controller hardware.

[0109] Step S3032: Based on the target load, determine the first correspondence between the power of the target motor and the air volume corresponding to the target load.

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

[0111] Specifically, the target motor can find the first correspondence between the power and air volume of the target motor corresponding to the target load in the storage device according to the target load.

[0112] It should be noted that the storage device can store the initial correspondence between power and airflow for various loads. The initial correspondence between power and airflow differs for different loads.

[0113] Optionally, the primary correspondence between power and airflow can be generated by fitting a series of operating point data (airflow and power data corresponding to each load) collected in the laboratory for each load. The number of operating point data points must be at least 15.

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

[0115] Specifically, the target motor can substitute the target air volume value into the first correspondence to calculate the target power value corresponding to the target air volume value.

[0116] Step S3034: Control the speed of the target motor according to the target power value so that the air volume of the target equipment reaches the target air volume value.

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

[0118] Step b1: Based on the target load, determine the second correspondence between the speed and power of the target motor corresponding to the target load.

[0119] The second correspondence is obtained by fitting the experimental speed and experimental power of the target motor under the target load.

[0120] Specifically, the target motor can look up the second correspondence between the speed and power of the target motor corresponding to the target load in the storage device according to the target load.

[0121] It should be noted that the storage device can store a second correspondence between rotational speed and power for various loads. The second correspondence between rotational speed and power differs for different loads.

[0122] Optionally, the second correspondence between speed and power can be generated by fitting a series of operating point data corresponding to power and speed collected in the laboratory for each load. The number of operating point data points must be at least 15.

[0123] Step b2: Based on the target power value and the second correspondence, control the speed of the target motor so that the air volume of the target equipment reaches the target air volume value.

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

[0125] Step b21: Adjust the speed of the target motor and obtain the current speed value.

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

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

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

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

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

[0131] Step b231: Calculate the first difference between the current power value and the target power value.

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

[0133] For example, the target motor can calculate the first difference by subtracting the target power value from the current power value.

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

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

[0137] Step b233: If the first difference is outside the preset difference range, then calculate the target speed value based on the target power value of the target motor.

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

[0139] Step b234: Calculate the second difference between the target speed value and the current speed value.

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

[0141] Step b235: Adjust the current speed 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 its current speed based on the second difference to ensure that the airflow of the target device reaches the target airflow 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 is greater than 0, the target motor decreases the current speed value; if the second difference is less than 0, the target motor increases the current speed value.

[0144] This application provides an airflow control method that obtains a target load corresponding to a target motor; based on the target load, a first correspondence between the power and airflow of the target motor corresponding to the target load is determined, ensuring that the determined first correspondence matches the target load, thereby ensuring the accuracy of the determined first correspondence. Based on the first correspondence, a target power value corresponding to the target airflow value is determined, ensuring the accuracy of the determined target power value.

[0145] Then, based on the target load, a second correspondence between the speed and power of the target motor corresponding to the target load is determined, ensuring that the determined second correspondence matches the target load and thus ensuring the accuracy of the determined second correspondence.

[0146] Based on the target load, a second correspondence between the target motor's speed and power is determined, ensuring that the determined second correspondence matches the target load and thus guarantees its accuracy. A first difference between the current power value and the target power value is calculated, ensuring the accuracy of the calculated first difference. If the first difference is within a preset range, the airflow of the target device is determined to have reached the target airflow value; if the first difference is outside the preset range, the target speed value is calculated based on the target motor's target power value, ensuring the accuracy of the calculated target speed value. A second difference between the target speed value and the current speed value is calculated, ensuring the accuracy of the calculated second difference. Based on the second difference, the current speed value of the target motor is adjusted to ensure that the airflow of the target device reaches the target airflow value. This ensures the accuracy of controlling the target motor's speed, thereby controlling the airflow of the target device to reach the target airflow value. The above method achieves simple and efficient control of the target device's airflow without requiring overly complex programming logic, thus facilitating secondary development and after-sales service.

[0147] To better illustrate the airflow control method provided in this application embodiment, as shown in Figure 4, this application embodiment provides a flowchart of the airflow control method. As shown in Figure 4, relevant variables and function initializations can be stored in the target motor. The relevant variables can represent the correspondence between each digital gear and the target airflow; the function initialization can be a first correspondence between the target motor's power and airflow, and a second correspondence between the target motor's speed and power. The PC can read and write gear application parameters, and then store these 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, when the motor detects a valid gear, it calls the corresponding stored gear parameters to output the target airflow value; when the motor detects different power segment code values ​​in the controller hardware, it calls the corresponding constant airflow model coefficient; airflow loop closed-loop control is performed based on the target airflow value and the constant airflow coefficient; the airflow loop outputs the target speed through FOC vector control and SVPWM output. Finally, the inverter drive module drives the airflow, and the inverter output module controls the airflow output. In addition, the actual speed of the output module is detected by measuring voltage, phase current, and rotational speed, and the actual speed and motor status are fed back to the main board to form a closed loop.

[0148] For example, Figure 5 shows a schematic diagram of the target motor. The target motor includes a motor interface, a central control unit, and the motor body. The motor interface includes multiple physical gear positions. There is a certain correspondence between the physical gear positions and the digital gear positions. A maximum of 2 physical gear positions can be output in combination. n-1 digital speed setting. The motor interface includes a transmitter and receiver line for user-input commands. Based on the user command, the physical speed setting is confirmed, and the digital speed setting is determined according to the correspondence between the physical and digital speed settings.
