Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.
[0047] The present invention will be described in detail below with reference to specific embodiments.
[0048] In some specific embodiments of the present invention, Figure 1 As shown, this solution provides a method for controlling an air conditioner, comprising:
[0049] Obtain the operating mode of the air conditioner and power the air conditioner through solar energy;
[0050] Determining that the indoor temperature reaches a preset temperature corresponding to the operating mode, obtaining a solar operating frequency band parameter of the solar power supply operating frequency band;
[0051] A control strategy is generated according to the solar energy operating frequency band parameters, and the operation of the air conditioner is controlled according to the control strategy.
[0052] It should be noted that after the air conditioner has been running for a period of time according to the selected operating mode, the indoor temperature has reached the preset temperature corresponding to the operating mode. At this time, in order to save energy, the compressor is adjusted to low-frequency operation. This situation causes frequency hopping in a certain frequency band during the process of solar energy supplying power to the air conditioner. The frequency band where the frequency hopping point exists is very likely to cause large fluctuations in the indoor ambient temperature, thereby affecting the user experience. At the same time, it will also cause certain vibrations to the pipelines, causing damage to related equipment and affecting the service life.
[0053] In some possible embodiments of the present invention, the step of obtaining solar operating frequency band parameters of the solar power supply operating frequency band specifically includes:
[0054] During the continuous acquisition time period, the characteristic values of the operating frequency band of the solar power supply are obtained;
[0055] generating a first operating frequency band characteristic curve corresponding to solar power supply according to the operating frequency band characteristic value;
[0056] All frequency hopping points in the first operating frequency band characteristic curve are obtained, and solar operating frequency band parameters are determined based on the first operating frequency band characteristic curve and all frequency hopping points.
[0057] Specifically, this embodiment provides an implementation method for obtaining the solar operating frequency band parameters of the solar power supply operating frequency band. By obtaining the operating frequency band characteristic values of the solar power supply within a continuous acquisition time period, the construction of the first operating frequency band characteristic curve of the solar power supply is realized. The operating frequency band characteristic values are used to reflect the change curve of the solar power supply within the continuous acquisition time period, and then by observing the changes in the curve, the frequency hopping point of the solar power supply is determined, and the solar operating frequency band parameters are determined based on the frequency hopping point and the first operating frequency band characteristic curve.
[0058] It should be noted that the characteristic values of the operating frequency band of solar power supply include relevant parameters for constructing the characteristic curve of the first operating frequency band. In order to save space, the present invention does not describe in too much detail how to obtain the characteristic values of the operating frequency band and how to construct the first operating frequency band characteristic curve through the characteristic values of the operating frequency band. In actual applications, the scheme for obtaining the characteristic values of the operating frequency band and constructing the characteristic curve according to the corresponding characteristic values can refer to the settings of related fields.
[0059] In some possible embodiments of the present invention, the step of obtaining all frequency hopping points in the first operating frequency band characteristic curve specifically includes:
[0060] Get N preset collection durations within a continuous collection time period, where N is a positive integer greater than or equal to 2;
[0061] Extract all frequency hopping characteristic values within N preset acquisition time lengths, and make judgments based on the frequency hopping characteristic values;
[0062] If it is determined that the variation range of the frequency hopping characteristic value is greater than the first preset frequency hopping range, the coordinate corresponding to the frequency hopping characteristic value in the first operating frequency band characteristic curve is the frequency hopping point.
[0063] Specifically, this embodiment provides an implementation method for obtaining all frequency hopping points within the first operating frequency band characteristic curve. Since the number of operating frequency band characteristic values obtained within the continuous acquisition time period is huge, and the first operating frequency band characteristic curve constructed based on the operating frequency band characteristic values changes complexly, it is difficult to quickly locate the frequency hopping points. Therefore, the continuous acquisition time period is divided into N preset acquisition durations, that is, N preset acquisition time periods are set within the continuous acquisition time period, and the frequency hopping situation of the entire first operating frequency band characteristic curve is estimated based on the frequency hopping point situation within each preset acquisition time period.
[0064] Furthermore, by obtaining all frequency hopping characteristic values within all N preset acquisition time lengths and extracting frequency hopping characteristic values greater than the first preset frequency hopping amplitude, the frequency hopping point is determined according to the coordinates corresponding to the extracted frequency hopping characteristic values in the first operating frequency band characteristic curve.
[0065] In some possible embodiments of the present invention, the step of extracting all frequency hopping characteristic values within N preset acquisition time periods and making a judgment based on the frequency hopping characteristic values specifically includes:
[0066] Obtain the number of times the frequency hopping characteristic value appears within each preset acquisition time, and make a judgment based on the number of times the frequency hopping characteristic value appears;
[0067] If it is determined that the number of frequency hopping characteristic values appearing within the same preset collection time is greater than the first preset frequency hopping number, the corresponding coordinates of all frequency hopping characteristic values within the corresponding preset collection time in the first operating frequency band characteristic curve are taken as frequency hopping points.
[0068] Specifically, this embodiment provides an implementation method for judging based on the frequency hopping characteristic value. By acquiring all the frequency hopping characteristic values within the same preset acquisition time, when the number of occurrences of the frequency hopping characteristic value within the same preset acquisition time is greater than the first preset frequency hopping number, all the frequency hopping characteristic values within the preset acquisition time are used as frequency hopping points, and no longer compared one by one, thereby improving the efficiency of confirming the frequency hopping points within the same preset acquisition time. Therefore, when the number of frequency hopping characteristic values appearing within the same preset acquisition time reaches a certain level, even if the frequency hopping characteristic value does not reach the first preset frequency hopping amplitude, it will have a certain impact on the indoor temperature and cause certain vibrations to the pipeline.
[0069] In some possible embodiments of the present invention, the steps of generating a control strategy based on the solar operating frequency band parameters and controlling the operation of the air conditioner based on the control strategy specifically include:
[0070] Obtain the power supply parameters of the mains power supply and make judgments based on the power supply parameters;
[0071] If it is determined that the power supply parameters meet the preset supplementary power supply parameters, the solar power supply is supplemented by the mains power.
[0072] Specifically, this embodiment provides an implementation method for controlling the operation of the air conditioner according to the control strategy. By obtaining the power supply parameters of the mains power supply, it is determined whether the mains power can be used as a supplementary power supply. When the mains power can be used as a supplementary power supply to supplement the solar power supply, the mains power supplement can offset the temperature fluctuations of the compressor caused by the frequency hopping point when operating at a low frequency, thereby ensuring the stability of the indoor ambient temperature. At the same time, when solar energy and mains power are mixed for power supply, the occurrence of frequency hopping points can be avoided, thereby avoiding vibration of the pipeline when the compressor operates at a low frequency.
[0073] In some possible embodiments of the present invention, after determining that the power supply parameters meet the preset supplementary power supply parameters, the method further includes:
[0074] Obtaining hybrid power supply operating frequency band parameters of a hybrid power supply operating frequency band of solar power and mains electricity;
[0075] Constructing a second operating frequency band characteristic curve according to the hybrid power supply operating frequency band parameters, and making a judgment based on the second operating frequency band characteristic curve;
[0076] If it is determined that the number of frequency hopping points in the second operating frequency band characteristic curve is greater than a second preset frequency hopping number, the operating frequency of the compressor is increased.
[0077] Specifically, this embodiment provides an implementation method after the step of supplementing solar power supply with AC power. By acquiring the hybrid power supply operating frequency band parameters of solar power and AC power, a corresponding second operating frequency band characteristic curve is constructed. The number of frequency hopping points in the second operating frequency band characteristic curve is compared with the second preset frequency hopping number. When the number of frequency hopping points in the second operating frequency band characteristic curve is greater than the second preset frequency hopping number, the operating frequency of the compressor is increased in time to ensure the stability of the indoor temperature and avoid the problem of indoor temperature fluctuation caused by the existence of frequency hopping points in the process of hybrid power supply of solar power and AC power, which affects the user experience.
[0078] In some possible embodiments of the present invention, after determining that the power supply parameters meet the preset supplementary power supply parameters, the method further includes:
[0079] Obtaining hybrid power supply operating frequency band parameters of a hybrid power supply operating frequency band of solar power and mains electricity;
[0080] Constructing a second operating frequency band characteristic curve according to the hybrid power supply operating frequency band parameters, and making a judgment based on the second operating frequency band characteristic curve;
[0081] If it is determined that the amplitude of the frequency hopping point in the second operating frequency band characteristic curve is greater than the second preset frequency hopping amplitude, the operating frequency of the compressor is increased.
[0082] Specifically, this embodiment provides another implementation method after the step of supplementing solar power supply with AC power. By acquiring the hybrid power supply operating frequency band parameters of solar power and AC power, a corresponding second operating frequency band characteristic curve is constructed. According to the comparison between the amplitude of the frequency hopping point in the second operating frequency band characteristic curve and the second preset frequency hopping amplitude, when the amplitude of the frequency hopping point in the second operating frequency band characteristic curve is greater than the second preset frequency hopping amplitude, the operating frequency of the compressor is increased in time to ensure the stability of the indoor temperature and avoid the problem of indoor temperature fluctuation caused by the existence of frequency hopping points in the process of hybrid power supply of solar power and AC power, which affects the user experience.
[0083] In some possible embodiments of the present invention, the step of supplementing solar power supply with commercial power specifically includes:
[0084] Get the original carrier frequency of the solar power supply operating frequency band;
[0085] Determine the carrier frequency increase range based on the solar operating frequency band parameters and the original carrier frequency;
[0086] The electric energy supplemented by the mains is determined according to the increase in the carrier frequency.
[0087] Specifically, this embodiment provides an implementation method for supplementing solar power supply with AC power, by obtaining the original carrier frequency of the solar power supply operating frequency band and determining the corresponding carrier frequency increase amplitude in combination with the solar power operation frequency band parameters, and determining the electric energy level that needs to be supplemented by the AC power by the carrier frequency increase amplitude, so as to realize a hybrid power supply mode of accurately supplementing solar power supply with AC power, realize the offset of frequency hopping points, and ensure the stability of indoor ambient temperature when the compressor operates at a low frequency.
[0088] It should be noted that the carrier frequency increase amplitude constructed by the solar operating frequency band parameters and the original carrier frequency determines the electric energy that needs to be supplemented by the mains, ensuring that after the mains is supplemented into the power supply to form a mixed power supply, the fluctuation of the air conditioner's operating frequency band is within a stable range, that is, the supplemented mains can effectively offset or suppress the frequency hopping points in the solar power supply, avoiding the problem of fluctuations in indoor ambient temperature.
