[0002] An air conditioner is a device used to regulate indoor air temperature and is widely used in various environments such as homes, offices, shopping malls, hotels, and hospitals. Existing air conditioners typically contain a compressor and various pipes connected to the compressor. When the compressor is in use, it vibrates, which in turn causes the various pipes or other components connected to the compressor to vibrate, resulting in vibration and abnormal noise during the use of the air conditioner. Therefore, during the development of air conditioners, it is necessary to conduct vibration tests on the compressor and the various pipes or other components connected to the compressor during the testing process of air conditioner products to ensure the installation position of the compressor to reduce vibration and abnormal noise during the use of the air conditioner.

[0032] Figure 2 This is a flowchart of another control method provided in the embodiments of this application. Detailed Implementation

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0035] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0036] During the development of air conditioners, vibration tests are required on the compressor and its connected piping and other components during product testing to ensure proper compressor placement and prevent vibration and abnormal noise during operation. However, current vibration testing typically involves installing strain gauges on an air conditioner prototype. This prototype, created after the design phase based on drawings or models, is used to verify the design's effectiveness. It can be a complete functional model or a partial model with the compressor and connected piping. By detecting stress and vibration, the degree of compressor vibration is assessed, and the compressor's installation position is adjusted to minimize vibration and abnormal noise during operation. However, installing strain gauges is time-consuming and labor-intensive. For example, large commercial modular air conditioners often have numerous compressors and piping, requiring approximately 200 strain gauges for a single vibration test. Preparation work, such as welding, attaching, and calibrating the strain gauges, is time-consuming, resource-intensive, and difficult to guarantee the accuracy of the test results, impacting development efficiency and increasing costs.

[0037] According to a first aspect of the embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, a positioning method for a compressor is provided. The compressor is equipped with a gyroscope, and the positioning method includes:

[0038] Step S100: Establish the first model in the simulation program. The first model is the gyroscope model when the compressor is not running. Since the gyroscope is located on the compressor, a basic model usually needs to be set up in the simulation program before the first model. This basic model can be the model of the air conditioner prototype mentioned above in the simulation program. The basic model includes the model of the compressor itself when it is not running, as well as the model of the gyroscope on the compressor when it is not running, at which time the gyroscope's attitude is the initial attitude, i.e., the first model. It also includes the model of the pipes connected to the compressor and other structural models. The first model provides the model foundation for subsequent simulations.

[0039] Step S200: Based on the first model, a second model is established through a simulation program. The second model is a model of the gyroscope when the compressor is running at a first frequency. Under normal operating conditions, the compressor has its own specific frequency range, and different compressor models have different normal operating frequency ranges. Depending on the compressor, the first frequency can be arbitrarily selected from the compressor's corresponding normal operating frequency range; this disclosure does not specifically limit this. The compressor can operate normally at the first frequency. In the simulation program, the compressor's normal operation at the first frequency is used as the input excitation. At this time, the simulation program simulates the compressor's operation and establishes a new model. This new model can be called the first deterministic model. The first deterministic model can be understood as the compressor's equilibrium position at the first frequency, where compressor vibration is relatively small. The first deterministic model is based on the aforementioned basic model, derived when the compressor is running normally at the first frequency. Compared to the aforementioned basic model, the compressor's position changes in the first deterministic model. Correspondingly, the gyroscope's attitude changes in the first deterministic model; that is, the gyroscope has an angular velocity input. In the first deterministic model, the gyroscope model is the second model.

[0040] Step S300: Using a simulation program, obtain the attitude of the gyroscope in the second model. Based on the current signal of the second model, adjust the compressor position so that the gyroscope attitude after compressor position adjustment is consistent with the attitude of the gyroscope in the second model. Consistency here refers to the two being equal or their deviation being within a preset range. Since the second model is derived from the simulation program under ideal conditions, it is difficult to guarantee that the gyroscope attitude after compressor position adjustment will be equal to the gyroscope attitude in the second model. Therefore, a certain degree of error is allowed when adjusting the compressor position. As mentioned above, compared to the gyroscope in the first model, the gyroscope attitude changes in the second model. When the gyroscope attitude changes, it outputs a current signal. The simulation program can obtain the current signal of the second model. After obtaining the current signal of the second model, the position of the compressor in the air conditioner prototype mentioned above can be adjusted so that the gyroscope current signal after compressor position adjustment is equal to the current signal of the second model. The adjustment of the compressor position mentioned here refers to adjusting the compressor position in the air conditioner prototype as described above. In the air conditioner prototype, when the gyroscope current signal after compressor position adjustment equals the current signal of the second model, it indicates that the compressor position in the prototype corresponds to the compressor's normal operating position in the simulation program. Thus, when the compressor in the prototype is started, its vibration will be as close as possible to the compressor's normal operating position in the simulation program. In this way, the compressor, using the gyroscope as a reference, adjusts itself to its normal operating position through the simulation program, reducing compressor vibration and noise, and further minimizing vibration and abnormal noise during air conditioner use.

[0041] Through the above technical solution, during the vibration testing of the air conditioner prototype, a gyroscope is installed on the compressor and used as a reference. A simulation program is used to obtain the gyroscope's attitude during normal operation. Based on this simulated gyroscope attitude, the compressor is adjusted to its normal operating position. This reduces compressor vibration and noise, further minimizing vibration and abnormal noise during air conditioner use. Compared to related technologies that use strain gauges on the air conditioner prototype for vibration testing, the simulation program and gyroscope provide a more accurate assessment of the compressor's position during normal operation, ensuring accurate vibration test results. Furthermore, using simulation and gyroscopes eliminates the need for manual strain gauge welding, pasting, and calibration, reducing testing time, manpower, and resources, thus improving development efficiency and costs. Simultaneously, precise simulation calculations identify compressor loads, providing effective pipeline stress simulation results to guide pipeline design; and using gyroscopes to regulate compressor vibration reduces the need for vibration damping materials.

[0042] The aforementioned gyroscope can be set on a certain horizontal plane of the compressor in the air conditioner prototype. In this way, the initial attitude of the gyroscope can be adjusted to the zero position of the gyroscope. The zero position of the gyroscope usually refers to the output value of the gyroscope when there is no angular velocity input. That is, the gyroscope in the first model corresponds to the zero position of the gyroscope itself. In this way, it is easier to obtain the current signal of the second model when the second model is obtained.

[0043] In some implementations, step S300 may include step S301: obtaining the attitude of the gyroscope in the second model through a simulation program, obtaining the current signal of the second model based on the attitude of the gyroscope in the second model, and / or obtaining the moment of inertia J1 and angular momentum H1 of the equatorial axis of the gyroscope in the second model, and adjusting the position of the compressor based on the current signal of the second model and / or the moment of inertia J1 and angular momentum H1 of the equatorial axis of the gyroscope in the second model, so that the attitude of the gyroscope after the compressor position adjustment is consistent with the attitude of the gyroscope in the second model. Taking a common gyroscope as an example, a gyroscope has an equatorial axis. When the gyroscope's attitude changes, i.e., when there is an angular velocity input, the gyroscope can output a current signal. When the gyroscope's attitude changes, the force on the gyroscope's equatorial axis will change. By obtaining the force change on the equatorial axis, the rotational inertia J1 and angular momentum H1 of the equatorial axis can be obtained. Thus, the position of the compressor can be adjusted based on the rotational inertia J1 and angular momentum H1 of the equatorial axis, or based on the current signal output by the gyroscope in the second model. In this way, compared to directly adjusting the compressor's position, by first obtaining the force change or current signal change on the gyroscope's equatorial axis, the adjustment of the compressor's position can be more accurate, ensuring the accuracy of the adjusted compressor position.

[0044] Specifically, based on the current signal output by the gyroscope, the moment of inertia J1 and angular momentum H1 of the equatorial axis can be obtained. Correspondingly, based on the moment of inertia J1 and angular momentum H1 of the equatorial axis, the current signal output by the gyroscope can also be obtained.

[0045] In some implementations, when adjusting the compressor position based on the moment of inertia J1 and angular momentum H1 of the equatorial axis, the moment of inertia J1 and angular momentum H1 of the gyroscope in the second model can be obtained first. As mentioned above, the moment of inertia J1 and angular momentum H1 can be correlated and converted with the current signal. At this time, the current signal of the second model can be obtained based on the moment of inertia J1 and angular momentum H1, and then the compressor position is adjusted based on the current signal of the second model, so that the current signal of the gyroscope after the compressor position adjustment is equal to the current signal of the second model or the deviation between the two is within a first preset range, further ensuring the accuracy of the compressor position adjustment.

[0046] In other embodiments, when adjusting the compressor position according to the current signal of the second model, the current signal of the second model can be obtained. Based on the current signal, the moment of inertia J1 and angular momentum H1 of the equatorial axis of the gyroscope in the second model can be obtained. Then, based on the moment of inertia J1 and angular momentum H1, the compressor position is adjusted so that the moment of inertia and angular momentum of the equatorial axis of the gyroscope after the compressor position is adjusted are equal to or deviate from the moment of inertia J1 and angular momentum H1 within a second preset range, thereby further ensuring the accuracy of the compressor position adjustment.

[0047] Meanwhile, in some other implementations, the two implementations mentioned above can be used simultaneously, so as to obtain the adjusted positions of the two compressors, and based on the adjusted positions of the two compressors, the accuracy of the compressor position adjustment can be further guaranteed.

[0048] The positioning method in this application further includes step S400: obtaining the force F and torque M at the center of mass of the compressor when it runs at a first frequency; step S200 may include step S201: based on the force F, torque M, and the first model, using the force F and torque M as input excitations for the first model, and establishing a second model through a simulation program. The second model is a model of the gyroscope when the compressor runs at the first frequency. The center of mass is an abbreviation for the center of mass; the center of mass of the compressor can be understood as a point where the compressor's mass is concentrated. Obtaining the force F and torque M at the center of mass of the compressor when it runs at the first frequency allows for accurate acquisition of the compressor's state when running at the first frequency. Then, using the force F and torque M as input excitations for the first model, and establishing the second model through a simulation program. The force F and torque M here are used as input excitations for the first model. This can be understood as the force F and torque M serving as input signals for the first model in the simulation program. In this way, by using the force F and torque M as input signals, the first determined model can be obtained more accurately. Furthermore, the second model can also be more accurate, further ensuring the accuracy of the compressor positioning method in this application.

[0049] In some embodiments, in step S201, the vibration acceleration of the compressor cylinder when it operates at a first frequency can be obtained. Based on the vibration acceleration, the rotational acceleration of the compressor cylinder when it operates at the first frequency can be obtained. Based on the rotational acceleration, the center-of-gravity acceleration of the compressor cylinder when it operates at the first frequency can be obtained. Based on the center-of-gravity acceleration, the force F and torque M at the center of gravity of the compressor when it operates at the first frequency can be obtained. In this way, by obtaining the vibration acceleration and sequentially calculating the rotational acceleration and the center-of-gravity acceleration, the center-of-gravity acceleration of the compressor cylinder when it operates at the first frequency can be obtained, and finally the force F and torque M at the center of gravity can be calculated.

[0050] Specifically, 3N measurement points can be set on the compressor cylinder, where N is a positive integer, greater than or equal to 1. The vibration acceleration of the compressor cylinder at each of the 3N measurement points during operation at a first frequency is obtained. Based on the vibration acceleration of the compressor cylinder at the first frequency from every three measurement points, the rotational acceleration of the compressor cylinder at the first frequency is obtained. Based on the rotational acceleration of the compressor cylinder at the first frequency, the center-of-gravity acceleration of the compressor cylinder at the first frequency is obtained. Based on the center-of-gravity acceleration of the compressor cylinder at the first frequency, the sub-force F1 and sub-torque M1 at the center-of-gravity of the compressor cylinder at the first frequency are obtained. The average of multiple forces F1 is the force F, and the average of multiple sub-torques M1 is the torque M. For every three test points, the rotational acceleration of one compressor cylinder during operation at the first frequency can be obtained. Taking test points 1, 2, and 3 as examples, the vibration acceleration of test point 1 in the three directions is as follows: The vibration accelerations at test point 2 in the three directions measured are as follows: The vibration accelerations of test point 3 in the three directions measured are as follows: By measuring the vibration acceleration in three directions at the three test points mentioned above, the rotational acceleration of the compressor cylinder block in three directions when running at the first frequency is obtained. These three rotational accelerations can be understood as the radial acceleration, tangential acceleration, and normal acceleration of the cylinder block, respectively. Refer to the formula shown in Figure 1 for details.

[0051]

[0052] In Equation 1, the rotational acceleration that needs to be calculated is excluded. On both sides of the equal sign are two matrices. The matrix on the left side of the equal sign represents the difference in acceleration vectors between test point 1 and test point 2, and the matrix on the right side of the equal sign represents the difference in position coordinates between test point 1 and test point 2. The rotational acceleration can be calculated using the two test points. At this time, the value of test point 3 is used to correct the obtained rotational acceleration. The rotational acceleration can be calculated again using test point 3 and test point 1, and compared with the rotational acceleration calculated using test point 1 and test point 2 to ensure the accuracy of the calculated rotational acceleration.

[0053] The rotational acceleration in three directions is determined based on the compressor cylinder operating at a first frequency. According to the formula in Formula 2, the acceleration of the center of mass can be calculated.

[0054]

[0055] Based on the calculated acceleration of the center of mass Based on the formulas in Formula 3 and Formula 4 in Figure 1, the force F1 and torque M1 of the center of mass virgin are finally calculated.

[0056]

[0057] By measurement, the rotational acceleration of a compressor cylinder at a first frequency can be obtained. Through calculation, the center-of-gravity acceleration of N compressor cylinders at the first frequency can be calculated, and the center-of-gravity force F1 and torque M1 of a compressor at the first frequency can be calculated. When 3N measurement points are set on the compressor cylinder, the center-of-gravity force F1 and torque M1 of N compressors at the first frequency can be calculated. Based on the center-of-gravity force F1 and torque M1 of N compressors at the first frequency, a more accurate force F and torque M can be obtained. Thus, when the force F and torque M are used as input signals, the first determined model can be obtained more accurately. Furthermore, the second model can also be more accurate, further ensuring the accuracy of the compressor positioning method in this application.

[0058] Furthermore, the 3N measurement points can be set on the same plane on the outer surface of the compressor cylinder. In this way, the direction of vibration acceleration at each test point corresponds one-to-one, which facilitates the calculation of rotational acceleration.

[0059] As mentioned above, under normal operating conditions, a compressor has its own specific frequency range, and different compressor models have different normal operating frequency ranges. Depending on the compressor, the first frequency can be arbitrarily selected from the compressor's corresponding normal operating frequency range. Generally speaking, the normal operating frequency range of a compressor is generally between 20Hz and 100Hz. In this case, the first frequency can be greater than or equal to 20Hz and less than or equal to 100Hz. That is, the range of the first frequency can be between 20Hz and 100Hz.

[0060] According to a second aspect of the embodiments of this application, an electronic device is provided, including a memory and a controller, wherein the memory is used to store a computer program; and the controller is used to execute the steps of the computer program to implement the positioning method of the compressor described above.

[0061] According to a third aspect of the embodiments of this application, a compressor is provided, the compressor being provided with a gyroscope, the compressor being used to perform the compressor positioning method of any of the above, or further including the electronic equipment as described above.

[0062] In some embodiments, multiple gyroscopes are provided, each mounted on a support foot of the compressor. The support foot secures and supports the compressor. When gyroscopes are mounted on the support foot, the compressor's position during normal operation can be more accurately determined. Furthermore, when the compressor is positioned using a compressor positioning method, multiple second models are acquired through the multiple gyroscopes, and the current signals of these second models are obtained. These current signals allow for more precise adjustment of the compressor to its normal operating position, thus reducing compressor vibration and noise, and further minimizing vibration and abnormal noise during air conditioner operation.

[0063] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
