[0002] At present, the control waveform of compressor torque balance is a sine wave with consistent size, but single-cylinder or size-cylinder compressors have torque imbalance due to their own design problems, which can cause compressor vibration. Therefore, a torque compensation is needed when the force is uneven to keep the compressor torque in a balanced state and avoid compressor vibration. Thus, the control waveform of the compressor providing torque compensation is a sine wave with alternating sizes.

[0003] In related technologies, during the low-frequency operation of the compressor, the compressor is usually unevenly stressed, resulting in torque imbalance and causing compressor vibration. Therefore, a torque compensation is provided, and when the compressor operates at high frequency, the torque compensation is no longer needed.

[0070] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0071] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0072] As Figure 1 shown, an implementation flow diagram of a torque compensation parameter adjustment method provided by an embodiment of the present application is shown, which can specifically include the following steps:

[0073] S101, obtaining the current vibration amplitude of the compressor and the preset vibration amplitude corresponding to the compressor.

[0074] In an embodiment of the present application, for the compressor, the normal control parameters are initialized and configured, and then it is judged whether the vibration sensor is correctly connected. If not, the sensor fault is reported, and if yes, the vibration information of the compressor is obtained, including the vibration frequency, vibration amplitude and vibration direction of the compressor, etc. In this way, through the vibration sensor, the current vibration amplitude of the compressor can be obtained.

[0075] In addition, in an embodiment of the present application, for the compressor, the vibration amplitude is set in advance, which is the reasonable vibration amplitude that the compressor can accept, i.e. the maximum vibration amplitude set for operation. Therefore, the preset vibration amplitude corresponding to the compressor is obtained, and the current vibration amplitude of the compressor is compared with the preset vibration amplitude corresponding to the compressor to determine whether the vibration of the compressor is within a reasonable range.

[0076] S102, in the case that the current vibration amplitude is greater than the preset vibration amplitude, the following torque compensation parameter adjustment processing is performed.

[0077] S103, determining the vibration amplitude change of the compressor, and adjusting the torque compensation parameter of the compressor according to the vibration amplitude change.

[0078] In an embodiment of the present application, for the current vibration amplitude of the compressor and the preset vibration amplitude corresponding to the compressor, in the case that the current vibration amplitude is not greater than the preset vibration amplitude, it indicates that the vibration of the compressor is within a reasonable range, at this time, the torque compensation parameter of the compressor is no longer changed, and the current control is maintained.

[0079] In the case that the current vibration amplitude is greater than the preset vibration amplitude, it indicates that the vibration of the compressor is not within a reasonable range, at this time, the torque compensation parameter of the compressor needs to be changed (i.e., the torque compensation parameter is increased), and for this purpose, the following torque compensation parameter adjustment processing is performed: determining the vibration amplitude change of the compressor, and adjusting the torque compensation parameter of the compressor according to the vibration amplitude change, wherein the vibration amplitude change is the vibration amplitude change generated by the torque compensation of the compressor according to different parameters.

[0080] It should be noted that different parameters are respectively regarded as the torque compensation parameter of the compressor, and then the torque compensation of the compressor is performed according to different parameters, which will generate a vibration amplitude change, at this time, the torque compensation parameter of the compressor can be adjusted according to the vibration amplitude change, and in this way, by adjusting the torque compensation parameter of the compressor through the vibration amplitude change generated by the torque compensation of the compressor according to different parameters, the vibration of the compressor can be solved, and the use performance and user experience of the compressor can be improved.

[0081] Through the above description of the technical solutions provided by the embodiments of the present application, by obtaining the current vibration amplitude of the compressor and the preset vibration amplitude, in the case that the current vibration amplitude is greater than the preset vibration amplitude, the vibration amplitude change generated by the torque compensation of the compressor according to different parameters is determined, and the torque compensation parameter of the compressor is adjusted according to the vibration amplitude change. In this way, in the case that the vibration amplitude of the compressor is large, the torque compensation parameter of the compressor is adjusted through the vibration amplitude change generated by the torque compensation of the compressor according to different parameters, which can solve the vibration of the compressor, and improve the use performance and user experience of the compressor.

[0082] In addition, in the embodiments of the present application, in combination with the vibration sensor, a vibration condition of the compressor can be provided. With the adjustment of the parameters of the compressor and the change of the vibration condition, the torque compensation parameter is adjusted adaptively through the feedback of the change of the vibration condition, the torque compensation parameter can be seen from two aspects, one is the angle of compensation, and the other is the amplitude of compensation, the angle is adjusted first, the most suitable angle is found through the feedback of the change of the vibration condition, and then the amplitude is adjusted, the most suitable amplitude is found through the feedback of the change of the vibration condition, and in this way, the adjustment is repeated to form an adaptive adjustment of the best torque compensation parameter. Based on this, as shown in Figure 2 The method can specifically include the following steps:

[0083] S201, obtaining the current vibration amplitude of the compressor and the preset vibration amplitude corresponding to the compressor.

[0084] In the embodiments of the present application, this step is similar to the above step S101, and the embodiments of the present application will not be described one by one here.

[0085] S202, in the case that the current vibration amplitude is greater than the preset vibration amplitude, the following torque compensation parameter adjustment processing is performed.

[0086] In the embodiment of the present application, this step is similar to the above-mentioned step S102, and the embodiment of the present application will not be described one by one here.

[0087] S203, determining the first vibration amplitude change of the compressor, and adjusting the torque compensation angle of the compressor according to the first vibration amplitude change.

[0088] In the embodiment of the present application, the first vibration amplitude change of the compressor can be determined, and the torque compensation angle of the compressor is adjusted according to the first vibration amplitude change. Wherein, the first vibration amplitude change is the vibration amplitude change generated by the compressor according to different angles for torque compensation.

[0089] It should be noted that different angles are regarded as the torque compensation angle of the compressor, and then the compressor performs torque compensation according to different angles, which will generate the first vibration amplitude change, at this time, the torque compensation angle of the compressor can be adjusted according to the first vibration amplitude change.

[0090] Wherein, the torque compensation angle of the compressor is adjusted according to the first vibration amplitude change, which can refer to the method as shown in Figure 3 As shown in Figure 3 An implementation process schematic diagram of a torque compensation angle adjustment method provided by the embodiment of the present application is shown in

[0091] S301, obtaining the minimum angle, and regarding the minimum angle as the torque compensation angle of the compressor.

[0092] S302, controlling the compressor to perform torque compensation according to the minimum angle, and obtaining the first vibration amplitude of the compressor.

[0093] S303, obtaining the sum of the minimum angle and the preset angle step length, obtaining the target angle, and regarding the target angle as the torque compensation angle of the compressor.

[0094] S304, controlling the compressor to perform torque compensation according to the target angle, and obtaining the second vibration amplitude of the compressor.

[0095] S305, comparing the first vibration amplitude with the second vibration amplitude, and adjusting the torque compensation angle of the compressor according to the vibration amplitude comparison result.

[0096] In the embodiment of the present application, the minimum angle is obtained, and the minimum angle is regarded as the torque compensation angle of the compressor, and then the compressor can be controlled to perform torque compensation according to the minimum angle, and the first vibration amplitude of the compressor is obtained.

[0097] Then, the preset angle step (for example, the preset angle step can be 1) is added to the minimum angle, so that the sum of the minimum angle and the preset angle step is obtained as a target angle, the target angle is regarded as the torque compensation angle of the compressor, and then the compressor is controlled to perform torque compensation according to the target angle to obtain a second vibration amplitude of the compressor.

[0098] Thus, the first vibration amplitude and the second vibration amplitude are obtained through the above steps, the first vibration amplitude and the second vibration amplitude can be compared to obtain a vibration amplitude comparison result, the vibration amplitude comparison result represents the change of the first vibration amplitude, and the torque compensation angle of the compressor can be adjusted according to the vibration amplitude comparison result.

[0099] Among them, the vibration amplitude comparison result can be that the first vibration amplitude is greater than the second vibration amplitude, or the first vibration amplitude can not be greater than the second vibration amplitude. Therefore, if the first vibration amplitude is greater than the second vibration amplitude, the target angle is assigned to the torque compensation angle of the compressor (here, the target angle is assigned to the torque compensation angle of the compressor, so that when the torque compensation angle needs to be adjusted due to various accidents, the target angle can be used as a starting point, and repeated work can be reduced), the target angle is determined as the minimum angle, the second vibration amplitude is determined as the first vibration amplitude, and the step S303 is jumped to repeat the steps S303-S305, and if the first vibration amplitude is not greater than the second vibration amplitude, the minimum angle is assigned to the torque compensation angle of the compressor (here, the minimum angle is assigned to the torque compensation angle of the compressor, so that when the torque compensation angle needs to be adjusted due to various accidents, the minimum angle can be used as a starting point, and repeated work can be reduced).

[0100] In addition, a maximum angle can also be provided, the maximum angle is obtained, the maximum angle is regarded as the torque compensation angle of the compressor, the compressor is controlled to perform torque compensation according to the maximum angle to obtain a fifth vibration amplitude of the compressor, if the first vibration amplitude is not greater than the fifth vibration amplitude, the minimum angle is assigned to the torque compensation angle of the compressor, and if the first vibration amplitude is greater than the fifth vibration amplitude, the maximum angle is assigned to the torque compensation angle of the compressor. In this way, the adjustment of the torque compensation angle of the compressor is completed.

[0101] It should be noted that the minimum angle and the maximum angle differ due to the type of the compressor, and the minimum angle and the maximum angle are generally recorded in the normal control parameters of the initial initialization configuration. In addition, the purpose of comparing the fifth vibration amplitude generated when the compressor performs torque compensation according to the maximum angle with the first vibration amplitude generated when the compressor performs torque compensation according to the minimum angle is to avoid that the best angle found is only an unexpected angle, and to avoid that the direction of finding the best angle from the minimum angle is set in reverse.

[0102] S204, determine a second vibration amplitude change of the compressor, and adjust the torque compensation amplitude of the compressor according to the second vibration amplitude change.

[0103] In the embodiment of the present application, the second vibration amplitude change of the compressor can be determined, and the torque compensation amplitude of the compressor is adjusted according to the second vibration amplitude change. The second vibration amplitude change is the vibration amplitude change generated by the torque compensation of the compressor at different amplitudes.

[0104] It should be noted that the different amplitudes are regarded as the torque compensation amplitude of the compressor, and then the torque compensation of the compressor is performed at different angles, which can generate the second vibration amplitude change. At this time, the torque compensation amplitude of the compressor can be adjusted according to the second vibration amplitude change.

[0105] The torque compensation amplitude of the compressor can be adjusted according to the second vibration amplitude change. For details, refer to the method shown in Figure 4 The embodiment of the present application provides an implementation process diagram of a torque compensation amplitude adjustment method, as shown in Figure 4 The method can include the following steps:

[0106] S401, obtain a minimum amplitude, and regard the minimum amplitude as the torque compensation amplitude of the compressor.

[0107] S402, control the torque compensation of the compressor at the minimum amplitude, and obtain a third vibration amplitude of the compressor.

[0108] S403, obtain the sum of the minimum amplitude and a preset amplitude step, obtain a target amplitude, and regard the target amplitude as the torque compensation amplitude of the compressor.

[0109] S404, control the torque compensation of the compressor at the target amplitude, and obtain a fourth vibration amplitude of the compressor.

[0110] S405, compare the third vibration amplitude and the fourth vibration amplitude, and adjust the torque compensation amplitude of the compressor according to the vibration amplitude comparison result.

[0111] In the embodiment of the present application, the minimum amplitude is obtained, and the minimum amplitude is regarded as the torque compensation amplitude of the compressor. Then the torque compensation of the compressor can be controlled at the minimum amplitude, and the third vibration amplitude of the compressor is obtained.

[0112] Then, the preset amplitude step (for example, the preset amplitude step is 0.1) is added on the basis of the minimum amplitude, so that the sum of the minimum amplitude and the preset amplitude step is obtained, the target amplitude is obtained, and the target amplitude is regarded as the torque compensation amplitude of the compressor. Then the torque compensation of the compressor is controlled at the target amplitude, and the fourth vibration amplitude of the compressor is obtained.

[0113] Thus, after the above steps, the third vibration amplitude and the fourth vibration amplitude can be obtained, the third vibration amplitude and the fourth vibration amplitude can be compared, a vibration amplitude comparison result is obtained, the vibration amplitude comparison result represents the second vibration amplitude change, and the torque compensation amplitude of the compressor can be adjusted according to the vibration amplitude comparison result.

[0114] Wherein, for the vibration amplitude comparison result, it is possible that the third vibration amplitude is greater than the fourth vibration amplitude, and it is also possible that the third vibration amplitude is not greater than the fourth vibration amplitude. Therefore, if the third vibration amplitude is greater than the fourth vibration amplitude, the target amplitude is assigned to the torque compensation amplitude of the compressor (here, the target amplitude is assigned to the torque compensation angle of the compressor, so that when the torque compensation amplitude needs to be adjusted due to various unexpected needs, the target amplitude can be used as a starting point, and repeated work can be reduced), the target amplitude is determined as the minimum amplitude, the fourth vibration amplitude is determined as the third vibration amplitude, and the step S403 is jumped to, and the steps S403-S405 are repeatedly executed. If the third vibration amplitude is not greater than the fourth vibration amplitude, the minimum amplitude is assigned to the torque compensation amplitude of the compressor (here, the minimum amplitude is assigned to the torque compensation amplitude of the compressor, so that when the torque compensation amplitude needs to be adjusted due to various unexpected needs, the minimum amplitude can be used as a starting point, and repeated work can be reduced).

[0115] In addition, the maximum amplitude can also be provided, the maximum amplitude is obtained, the maximum amplitude is regarded as the torque compensation amplitude of the compressor, the compressor is controlled to perform torque compensation according to the maximum amplitude, the sixth vibration amplitude of the compressor is obtained, if the third vibration amplitude is not greater than the sixth vibration amplitude, the minimum amplitude is assigned to the torque compensation amplitude of the compressor, and if the third vibration amplitude is greater than the sixth vibration amplitude, the maximum amplitude is assigned to the torque compensation amplitude of the compressor. In this way, the adjustment of the torque compensation amplitude of the compressor is completed.

[0116] It should be noted that the minimum amplitude and the maximum amplitude are different for different types of compressors, and the minimum amplitude and the maximum amplitude are generally recorded in the initial initialization configuration of the normal control parameters. In addition, the purpose of comparing the sixth vibration amplitude generated when the compressor performs torque compensation according to the maximum amplitude with the third vibration amplitude generated when the compressor performs torque compensation according to the minimum amplitude is to avoid that the best amplitude found is only an unexpected amplitude, and to avoid that the direction of finding the best amplitude from the minimum amplitude is set in reverse.

[0117] The torque compensation parameter adjustment method provided by the embodiments of the present application will be described below in combination with specific examples.

[0122] Step 5, according to the vibration information feedback by the vibration sensor, judge whether the amplitude of vibration exceeds the maximum vibration amplitude M set for operation, if yes, it is in the unreasonable range.

[0123] Step 6, if not, it is in the reasonable range, at this time, the torque compensation parameter is not changed, and the current control is maintained.

[0124] Step 7, if not, the torque compensation parameter is changed, the torque compensation parameter is increased, n=0 is set, a minimum angle AngleMin is provided to the torque compensation angle Angle, and the first vibration amplitude An is obtained.

[0125] Step 8, AngleMin+1 is provided to the torque compensation angle Angle, and the second vibration amplitude An+1 is obtained.

[0129] Step 12, a maximum angle AngleMax is provided to the torque compensation angle Angle, a third vibration amplitude Am is obtained, and the size of Am and An is compared, if Am is greater than An, AngleMin is filled into the torque compensation angle Angle, if Am is less than An, AngleMax is filled into the torque compensation angle Angle.
