The singular terms "one" and "the" may also include plural forms.

[0048] As described in the background art, during the operation of the air conditioner, it is necessary to collect current information through resistance to control and monitor the operating status of the air conditioner system.

[0049] Since the resistor has a certain amount of inductance and capacitance, its frequency response characteristics may be affected, and it will collect certain noise signals, making it unable to accurately reflect the instantaneous changes in current. Therefore, it is unable to detect abnormal voltage conditions in time, resulting in more serious electromagnetic noise when the motor is running, affecting the user experience.

[0050] In order to solve the above problems, the present application provides an air conditioning control method, an electronic device, a storage medium and an air conditioner.

[0051] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart of the main steps of an air conditioning control method according to an embodiment of the present application. Figure 1 As shown, the air conditioning control method in the embodiment of the present application mainly includes the following steps S101 to S104.

[0052] Step S101: in response to the air conditioner starting to run, obtaining the three-phase current of the motor;

[0053] Step S102: obtaining corresponding operating voltage values ​​based on the three-phase currents;

[0054] Step S103: determining whether the operating voltage value is within a preset voltage range;

[0055] Furthermore, if the operating voltage value is within the preset voltage range, no processing is performed and step S101 is continued; if the operating voltage value is not within the preset voltage range, step S104 is executed.

[0056] Step S104: obtaining a correction voltage value corresponding to the operating voltage value, and controlling the operation of the motor based on the correction voltage value.

[0057] Based on the method described in steps S101 to S104 above, the corresponding operating voltage can be calculated through the three-phase current, and it can be determined whether the operating voltage is within the normal voltage range. If not, corresponding corrections are made in time according to the abnormal situation to maintain the stability of the motor input voltage and the motor speed, thereby reducing the electromagnetic noise generated when the motor is running, improving the reliability of the air conditioner operation, and enhancing the user experience.

[0058] The above steps S101 to S104 are further explained below.

[0059] At present, the motor of the air conditioner can be a three-phase motor. The three-phase motor has the advantages of low power consumption, stable operation, and high efficiency. It can meet the power requirements of the air-conditioning system under different working conditions. It has a simple structure, is sturdy and durable. By cooperating with a suitable control circuit, it can achieve precise control of the air-conditioning operating state, thereby providing users with a comfortable indoor environment.

[0060] When the air conditioner is running, current information can be collected through resistors, including a single-resistor sampling method and a three-resistor sampling method.

[0061] See attached Figure 2 , Figure 2 FIG. 1 is a circuit diagram of a single resistor sampling according to an embodiment of the present application. Figure 2 As shown, it includes a power supply, a three-phase inverter bridge and a resistor R1, wherein the three-phase inverter bridge is composed of six power switching devices, which are divided into an upper bridge arm and a lower bridge arm, and each phase has an upper bridge arm switch and a lower bridge arm switch. By controlling the on and off of these switching devices, the three-phase winding of the motor can be powered.

[0062] For example, when the upper arm switches Q1, Q3, and Q5 are turned on and the lower arm switches Q2, Q4, and Q6 are turned off, the A, B, and C phases of the motor are respectively connected to the positive pole of the DC power supply, and the motor winding obtains a forward voltage. Conversely, when the states of the upper and lower arm switches are reversed, the motor winding obtains a reverse voltage. By continuously switching the switch states, the motor can continue to operate.

[0063] Furthermore, when the air conditioner operates normally, the sampling resistor R1 will collect the current of the three-phase motor when the lower bridge arm is turned on.

[0064] Figure 2 The advantages of the single resistor sampling method shown are that it is simple to use and low cost. However, due to the presence of certain inductance and capacitance in the resistor, its frequency response characteristics are affected, and certain clutter signals will be collected, making it unable to accurately reflect the instantaneous changes of the current, which can easily cause serious electromagnetic noise when the motor is running.

[0065] Therefore, in some implementations of step S101, a three-resistance sampling method can be used. The three-resistance sampling has high precision and accuracy and can measure the current under the mains and DC power supply. When the current flows through the current sensor, the generated voltage signal can be offset by the current in the compensator, eliminating the error caused by the compensation voltage. In this way, a high-precision current measurement can be achieved, and the frequency response characteristics are good, which can accurately reflect the instantaneous change of the current.

[0066] See attached Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a three-resistance sampling circuit according to an embodiment of the present application. Figure 3 As shown, unlike single-resistance sampling, the three-phase lower bridge arms Q2, Q4, and Q6 are provided with respective sampling resistors R1, R2, and R3. When the air conditioner operates normally, the sampling resistors R1, R2, and R3 of the three-phase lower bridge arms will respectively collect the current of the phase when the lower bridge arms are turned on, and obtain the three-phase currents A1, A2, and A3 of the motor.

[0067] It should be pointed out that Figure 3 In the three-resistance sampling shown, since the currents flowing through the resistors RI, R2, and R3 have different directions, some are positive and some are negative, a phase shift circuit needs to be added before the currents can be sent to the analog-to-digital converter (ADC) for sampling.

[0068] Among them, the role of the ADC circuit is to convert analog signals into digital signals. In the three-resistance sampling scheme, the current signal from the resistor is an analog signal, and the digital control system (such as a microprocessor, etc.) can usually only process digital signals. Therefore, the ADC circuit will sample the input analog current signal at a certain sampling frequency and quantize it into a digital value for subsequent digital signal processing and analysis.

[0069] Specifically, during sampling, since the currents flowing through the resistors RI, R2, and R3 have different directions, some positive and some negative, in order to avoid invalid levels due to a too narrow window, the effective current collected each time can be the current of two phases of the three-phase currents A1, A2, and A3.

[0070] The above is a further description of step S101. The following is a further description of step S102.

[0071] In some implementations of the above step S102, the corresponding operating voltage value may be calculated by using the three-phase current and the resistance value.

[0072] According to conventional parameters, the resistance of a single resistor is generally 100mΩ, and the resistance of three resistors is generally 35mΩ. The collected phase current value is converted into a voltage value of about 0.1V. Since the voltage value at this time is small, the weak input voltage signal can be greatly amplified by the operational amplifier to reach the level range that the subsequent circuit can effectively process. After amplification by the operational amplifier, it can be accurately converted into a digital signal by the ADC circuit for further processing.

[0073] Specifically, the calculated voltage value may be amplified by an operational amplifier by about 10 times to obtain operating voltage values, including a first operating voltage value V1 , a second operating voltage value V2 , and a third operating voltage value V3 .

[0074] The above is a further description of step S102. The following is a further description of step S103.

[0075] In some implementations of the above step S103, before determining whether the operating voltage value is within the preset voltage range, the preset voltage range may be obtained by first performing the following steps S11-S13.

[0076] Step S11: obtaining a preset voltage curve of the motor;

[0077] The preset voltage curve includes preset voltage values ​​corresponding to different speeds of the motor under a fixed load.

[0078] Specifically, in the early test stage of the motor, when the motor and load are fixed, the normal voltage values ​​corresponding to different speeds can be tested. This voltage value is a relatively stable state of the motor under normal circumstances, so that the preset voltage curve of the motor can be obtained.

[0079] Step S12: obtaining preset voltage values ​​V1', V2', V3' corresponding to the current speed of the motor based on the preset voltage curve;

[0080] Step S13: superimposing the preset voltage value with the preset error to obtain a preset voltage range.

[0081] Specifically, the preset voltage values ​​V1', V2', and V3' may be superimposed with an error of ±3% to obtain a preset voltage range.

[0082] Furthermore, it can be determined whether the operating voltage value is within a preset voltage range.

[0083] The above is a further description of step S103. The following is a further description of step S104.

[0084] In some implementations of executing the above step S104, if the operating voltage value is within the preset voltage range, the motor operation can continue to be controlled based on the operating voltage value without any other processing.

[0085] In some implementations of executing the above step S104, if the operating voltage value is not within the preset voltage range, a corrected voltage value corresponding to the operating voltage value may be obtained, and the motor operation may be controlled based on the corrected voltage value.

[0086] The operating voltage value may also be obtained repeatedly, such as twice. When the repeatedly obtained operating voltage value is still not within the preset voltage range, a corrected voltage value corresponding to the operating voltage value may be obtained, and the motor operation may be controlled based on the corrected voltage value.

[0087] In some implementations, the corrected voltage value corresponding to the operating voltage value may be obtained through the following steps S21-S23.

[0088] Step S21: obtaining a deviation voltage value based on the operating voltage value and the corresponding preset voltage value;

[0089] Specifically, a difference between the operating voltage value and the corresponding preset voltage value may be obtained as the deviation voltage value.

[0090] Step S22: obtaining a correction coefficient based on the deviation voltage value;

[0091] The correction coefficient may be the same as the deviation voltage value, or may be a ±1% error added to the deviation voltage value, which is not limited here.

[0092] Step S23: Obtaining a corrected voltage value based on the correction coefficient.

[0093] Specifically, the operating voltage value and the correction coefficient may be added to obtain the corrected voltage value V.

[0094] Further, the operation of the motor may be controlled based on the corrected voltage value, which may specifically include the following steps S31-S32.

[0095] Step S31: obtaining two valid operating voltage values ​​among a first operating voltage value, a second operating voltage value and a third operating voltage value;

[0096] Since the effective current collected each time is the current of two phases among the three-phase currents A1, A2, and A3, the obtained effective operating voltage value is also two voltage values ​​among V1, V2, and V3, that is, two positive voltage values ​​among V1, V2, and V3.

[0097] Step S32: Control the motor operation based on the two effective operating voltage values.

[0098] In some implementations, step S32 may include the following steps S321-S323:

[0099] Step S321: obtaining the effective operating voltage value which deviates less from the preset voltage range among the two effective operating voltage values;

[0100] Among them, one of the two valid operating voltage values ​​may be outside the preset voltage range, or both of the two valid operating voltage values ​​may not be within the preset voltage range. Therefore, when one valid operating voltage value is outside the preset voltage range, another valid operating voltage value within the preset voltage range can be obtained; when both valid operating voltage values ​​are not within the preset voltage range, the valid operating voltage value with a lower error among the two valid operating voltage values ​​can be obtained.

[0101] Step S322: obtaining a corrected voltage value based on the effective operating voltage value that deviates less from the preset voltage range;

[0102] Specifically, the difference between the effective operating voltage value with a lower error and the corresponding preset voltage value can be obtained as the deviation voltage value, and a correction coefficient can be obtained based on the deviation voltage value. Then, the effective operating voltage value with a lower error and the correction coefficient are added to obtain the corrected voltage value V.

[0103] Step S323: Control the motor operation based on the corrected voltage value.

[0104] Specifically, the input voltage of the motor can be modified to a correction voltage value V, and the operation of the motor can be controlled based on the correction voltage value V.

[0105] Furthermore, when both effective operating voltage values ​​are outside the preset voltage range and after the motor operation is controlled based on the corrected voltage value, if there is still an effective operating voltage value that deviates from the preset voltage range among the two effective operating voltage values, the average value of the two effective operating voltage values ​​can be obtained, and the corrected voltage value can be obtained again based on the average value, and the motor operation can be controlled based on the corrected voltage value until both effective operating voltage values ​​are within the preset voltage range.

[0106] The above is the description of step S104.

[0107] For further information, see Appendix Figure 4 , Figure 4 It is a main flow chart of an air conditioning control method according to an embodiment of the present application.

[0108] like Figure 4 As shown, in response to the air conditioner starting to run, the three-phase currents A1, A2, and A3 of the motor are obtained in real time;

[0109] The corresponding operating voltage values ​​V1, V2, V3 are obtained through the three-phase currents A1, A2, A3 and the resistance values ​​of resistors R1, R2, R3;

[0110] Obtain a preset voltage curve of the motor, obtain preset voltage values ​​V1', V2', V3' corresponding to the current speed of the motor based on the preset voltage curve, and superimpose preset errors on the preset voltage values ​​V1', V2', V3' to obtain a preset voltage range;

[0111] Determine whether two valid operating voltage values ​​among the operating voltage values ​​V1, V2, and V3 are within a preset voltage range;

[0112] Further, if the two effective operating voltage values ​​are both within the preset voltage range, the motor operation is continued to be controlled based on the operating voltage value;

[0113] If one of the two valid operating voltage values ​​is not within the preset voltage range, the valid operating voltage value is repeatedly obtained twice, and when the two repeatedly obtained valid operating voltage values ​​are both within the preset voltage range, the motor operation is continued to be controlled based on the operating voltage value; when one of the two repeatedly obtained valid operating voltage values ​​is not within the preset voltage range, a corrected voltage value V is obtained based on the other valid operating voltage value within the preset voltage range, and the motor operation is controlled based on the corrected voltage value V until the operating voltage value is within the preset voltage range;

[0114] If both valid operating voltage values ​​are outside the preset voltage range, the valid operating voltage values ​​are repeatedly obtained twice; when the two repeatedly obtained valid operating voltage values ​​are both within the preset voltage range, the motor operation is continued to be controlled based on the operating voltage value; when one of the two repeatedly obtained valid operating voltage values ​​is outside the preset voltage range, a correction voltage value V is obtained based on the other valid operating voltage value within the preset voltage range, and the motor operation is controlled based on the correction voltage value V, and the operating voltage value is within the preset voltage range; when the two repeatedly obtained valid operating voltage values ​​are still not within the preset voltage range, a correction voltage value V is obtained based on the valid operating voltage value with a lower error among the two valid operating voltage values, and the motor operation is controlled based on the correction voltage value V, and if there is still an effective operating voltage value that deviates from the preset voltage range among the two obtained valid operating voltage values, the average value of the two valid operating voltage values ​​is obtained, the correction voltage value V is obtained again based on the average value, and the motor operation is controlled based on the correction voltage value V until both valid operating voltage values ​​are within the preset voltage range.
