However, in actual work, the unit is used for a long time, and there is dust and rust, or the structure is deformed due to bumping and extrusion during transportation and installation.

[0045] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0046] Please refer to Figure 1 , Figure 1 is a flow chart of a control method of a compressor according to an exemplary embodiment, which comprises the following steps:

[0047] S101, during the operation of the compressor, acquiring a detection value of the pipeline of the compressor;

[0048] S102, when the detection value exceeds a preset value, collecting the vibration amplitude and the operating frequency of the pipeline of the compressor;

[0049] S103, determining a target operating frequency which needs to be shielded by the compressor according to the vibration amplitude and the operating frequency;

[0050] S104, controlling the compressor to operate by skipping the target operating frequency.

[0051] The detection value of the pipeline of the compressor can be the value of the strain force of the pipeline of the compressor, or the value of other parameters of the pipeline of the compressor. The detection value of the pipeline of the compressor is explained and described as the value of the strain force of the pipeline of the compressor. Specifically, strain gauges are arranged on both sides of the pipeline of the compressor. The vibration amplitude of the pipeline of the compressor at the current operating frequency during the operation of the compressor is collected by detecting the strain of the strain gauges. When the detection value of the strain gauges exceeds the preset value, the corresponding vibration amplitude of the pipeline of the compressor at the current operating frequency of the compressor when the preset value is exceeded is recorded by an infrared distance sensor, and the vibration amplitude and the current operating frequency of the compressor of the vibration amplitude are recorded.

[0052] In actual use, the preset value can be set to, but is not limited to, 85με (με is the unit symbol of micro-strain). In actual experiments, when the detection value on the pipeline of the compressor exceeds 85με during the operation of the compressor, the resonance of the operating frequency of the compressor and the structure of the unit will cause more obvious sound. In addition, when the preset value is set to 85με, when the collection of the shielding point set of the operating frequency of the compressor is completed, more operating frequencies can be collected, which will cause relatively large noise when the compressor operates at the operating frequency. When the preset value is set to be higher than 85με, for example, 90με, when the collection of the shielding point set of the operating frequency of the compressor is completed, the collection of the shielding point set may not be sufficient.

[0053] Further, according to the vibration amplitude and the operating frequency, the target operating frequency which needs to be shielded in the compressor operation is determined, so that the target operating frequency which needs to be shielded is automatically collected in the compressor operation process, and the compressor operation is controlled to skip the target operating frequency, so as to reduce the case that the compressor reaches certain specific operating frequencies and resonates with the unit structure to cause noise and abnormal sound, and meanwhile, the pipeline connected to the compressor is prone to be broken in the case of long-time resonance, so that the occurrence of certain specific operating frequencies of the compressor can further reduce the case of pipeline breakage of the compressor.

[0054] For step S103, in one embodiment, according to the vibration amplitude and the operating frequency, the target operating frequency which needs to be shielded in the compressor operation is determined, including: recording the vibration amplitude in a historical amplitude collection set, and recording the operating frequency corresponding to the vibration amplitude in a shielding point set, wherein the maximum number of vibration amplitudes in the historical amplitude collection set is a preset number, and the maximum number of operating frequencies in the shielding point set is a preset number; and taking the operating frequencies in the shielding point set as the target operating frequency.

[0055] Specifically, the preset number is N, when the number of vibration amplitudes recorded in the historical amplitude collection set is less than N, the current collected vibration amplitude is directly recorded in the historical amplitude collection set, and the operating frequency corresponding to the current collected vibration amplitude is recorded in the shielding point set.

[0056] In actual application process, when the compressor is operated for the first time, N current collected vibration amplitudes are directly recorded in the historical amplitude collection set, and the operating frequency corresponding to the current collected vibration amplitude is recorded in the shielding point set, so that the shielding point set can collect N shielding points in the compressor operation.

[0057] When N vibration amplitudes have been recorded in the historical amplitude collection set, and the current collected vibration amplitude is greater than the minimum value in the historical amplitude collection set, the minimum value in the historical amplitude collection set is replaced by the current collected vibration amplitude, and the operating frequency corresponding to the minimum value in the shielding point set is replaced by the operating frequency corresponding to the current collected vibration amplitude.

[0058] In the actual application process, after N vibration amplitudes are recorded in the historical amplitude collection set, the current collected vibration amplitude is compared with the vibration amplitudes in the historical amplitude collection set. If the current collected vibration amplitude is greater than the minimum value of the historical amplitude collection set, the current collected vibration amplitude is replaced with the minimum value of the historical amplitude collection set, and the operating frequency corresponding to the current collected vibration amplitude is replaced with the operating frequency corresponding to the minimum value of the shielding point set. The replaced operating frequency in the shielding point set is the operating frequency corresponding to the minimum value in the historical amplitude collection set, so as to ensure that the operating frequencies in the shielding point set are the relatively maximum influence values that cause resonance between the compressor and the unit structure during operation.

[0059] After the minimum value in the historical amplitude collection set is replaced with the current collected vibration amplitude, and the operating frequency corresponding to the minimum value in the shielding point set is replaced with the operating frequency corresponding to the current collected vibration amplitude, the replaced minimum value in the historical amplitude collection set is recorded in the preliminary amplitude set, the operating frequency corresponding to the replaced minimum value in the historical amplitude collection set is recorded in the preliminary shielding point set, and the replacement count value is increased by a preset value.

[0060] After the replacement count value is increased by the preset value, the replacement count value is divided by the preset number to obtain a proportion value; according to the proportion value, the maximum value of the number of operating frequencies in the shielding point set is obtained.

[0061] The replaced minimum values in the preliminary amplitude set are sorted in descending order to obtain the first m replaced minimum values in the preliminary amplitude set.

[0062] The operating frequencies corresponding to the first m replaced minimum values are obtained from the preliminary shielding point set, and the operating frequencies corresponding to the first m replaced minimum values are added to the shielding point set.

[0063] Specifically, the replacement count value is divided by the preset number to obtain a proportion value, and then according to the proportion value, the maximum value of the number of operating frequencies in the shielding point set is obtained, and the number m of the maximum value of the number of operating frequencies in the shielding point set is increased by the preset number N, so as to ensure that when the detection value of the pipeline of the compressor exceeds the preset value too much, the number of target operating frequencies in the shielding point set is increased to reduce the possibility of resonance between the compressor and the unit structure during operation, and further reduce noise.

[0064] After the number of the shielding point set is adjusted, the replaced minimum values in the preliminary amplitude set are sorted in descending order, the first m replaced minimum values are obtained from the sorted preliminary amplitude set, and the operating frequencies corresponding to the first m replaced minimum values are obtained from the preliminary shielding point set and added to the shielding point set.

[0065] According to the proportion value, a maximum value of the number of running frequencies in the shielding point set is obtained, and an increase number is obtained, comprising:

[0066] When the proportion value is greater than a first preset proportion value, the increase number is set as a first preset increase number;

[0067] When the proportion value is greater than a second preset proportion value, the increase number is set as a second preset increase number, wherein the second preset proportion value is greater than the first preset proportion value, and the second preset increase number is greater than the first preset increase number.

[0068] Specifically, the count value is L, the number of the shielding point set Y is y (the initial value of y is N), the first preset proportion value is 40%, the second preset proportion value is 70%, the first preset increase number is 0.2N (i.e. m=0.2N), and the second preset increase number is 0.4N (i.e. m=0.4N).

[0069] When L / y<40%, the number y of the shielding point set is unchanged and is still the preset number N.

[0070] When L / y>40%, the number y of the shielding point set is increased by 0.2 times of the preset number N, and the number y of the set Y is rounded up.

[0071] When L / y>70%, the number y of the shielding point set is increased by 0.4 times of the preset number N, and the number y of the set Y is rounded up.

[0072] The number of the shielding point set is increased according to different proportions, which can further guarantee that the resonance of the compressor running process and the structure of the unit is reduced as much as possible in the case that the detection value exceeds the preset value too much, thereby reducing the noise.

[0073] Please refer to Figure 2 , Figure 2 is a flowchart of a compressor control method according to an example embodiment Figure 1 In an implementation, in the normal running process of the working unit where the compressor is located, it is judged whether the compressor is started for the first time, if yes, the compressor frequency PID (proportion-integral-derivative) adjustment is performed, the strain force on the pipeline in the running of the compressor is detected, and a detection value is obtained,

[0074] Please refer to Figure 2, after the detection value of the compressor pipeline is acquired, if the detection value exceeds 85με, the vibration amplitude of the pipeline of the compressor at the current operating frequency is recorded, and the vibration amplitude is recorded in a historical amplitude collection set X, and the operating frequency corresponding to the vibration amplitude is recorded in a shielding collection set Y, wherein the operating frequency in the shielding collection set Y is a target operating frequency that needs to be shielded during operation of the compressor.

[0075] When the shielding point set collection of the operating frequency of the compressor reaches N, the currently collected vibration amplitude is compared with the minimum value of the vibration amplitudes in the historical amplitude collection set X,

[0076] If the currently collected vibration amplitude is less than or equal to the minimum value, the operation continues.

[0077] If the currently collected vibration amplitude is greater than the minimum value, it is determined whether the number of recorded vibration amplitudes exceeds y,

[0078] If the number of recorded vibration amplitudes reaches y, the currently collected vibration amplitude is replaced with the minimum value of the historical amplitude collection set X, and the operating frequency corresponding to the currently collected vibration amplitude is replaced with the operating frequency corresponding to the minimum value of the set Y in the shielding point set;

[0079] After the currently collected vibration amplitude is replaced with the minimum value of the historical amplitude collection set X, and the operating frequency corresponding to the currently collected vibration amplitude is replaced with the operating frequency corresponding to the minimum value of the set X in the shielding point set Y, the minimum value of the historical amplitude collection set X that is replaced is recorded in a preliminary amplitude set H, the operating frequency corresponding to the minimum value of the historical amplitude collection set X that is replaced is recorded in a preliminary shielding point set G, and a replacement count value L is increased by a preset value,

[0080] If the number of recorded vibration amplitudes does not reach y, the operating frequency corresponding to the operating frequency corresponding to the currently collected vibration amplitude is recorded in the set Y.

[0081] It is determined whether the shielding point set Y is collected, and when the shielding point set collection of the operating frequency of the compressor is completed, the ratio of the count value L to y is compared:

[0082] When L / y<40%, the number y of the shielding point set remains unchanged and is still the preset number N.

[0083] When L / y>40%, the number y of the shielding point set is increased by 0.2 times the preset number N, and the value of y becomes 1.2N, wherein the number y is rounded up.

[0084] When L / y>70%, the number y of the shielding point set is increased by 0.4 times the preset number N, and the value of y becomes 1.4N, wherein the number y is rounded up.

[0085] determining whether the value of y changes:

[0086] If the value of y does not change, continue running;

[0087] If the value of y changes, according to the proportional value of L / y, obtain the number m of y increases, adjust the value of y, and adjust the running frequency in the shielding point set Y at the same time;

[0088] Specifically, after the number of shielding point sets Y is adjusted, sort the replaced minimum values of the preliminary amplitude set H in descending order, obtain the first m replaced minimum values from the preliminary amplitude set H after sorting, and then add the running frequencies corresponding to the first m replaced minimum values from the preliminary shielding point set G to the shielding point set Y.

[0089] During the normal operation of the working unit where the compressor is located, it is determined whether the compressor is started for the first time. If not, it is determined whether the compressor running time reaches a preset time length Z:

[0090] If the compressor running time reaches the preset time length, clear the historical amplitude collection set X, the shielding point set Y, the preliminary amplitude set H, the preliminary shielding point set G, and the count value L;

[0091] If the compressor running time does not reach the preset time length, control the compressor to skip the running frequency in the shielding point set Y and continue running until the compressor is shut down. After confirming that the compressor is shut down, clear the historical amplitude collection set X, the shielding point set Y, the preliminary amplitude set H, the preliminary shielding point set G, and the count value L.

[0092] See Figure 1 For step S104, control the compressor to run at the target running frequency.

[0093] Specifically, when the compressor does not run to the target running frequency during the frequency increasing process, control the running frequency of the compressor to increase by a preset value to skip the target running frequency;

[0094] When the compressor does not run to the target running frequency during the frequency decreasing process, control the running frequency of the compressor to decrease by a preset value to skip the target running frequency.

[0095] The preset value can be 1 or other values. In actual application, the compressor runs at a frequency avoiding the shielding point set during the running of the compressor. If the running frequency that needs to be shielded is encountered during the frequency increase of the compressor, the control frequency is automatically increased by one to skip the running frequency and continue running. If the running frequency that needs to be shielded is encountered during the frequency decrease of the compressor, the control frequency is automatically decreased by one to skip the running frequency and continue running. If the continuous frequency needs to be skipped, the control is always increased or decreased by one to process until the running frequency that needs to be shielded is skipped.

[0096] In the present application, when the running time of the compressor is greater than the preset time, or when the unit in which the compressor is located is shut down, the historical amplitude collection set, the shielding point set, the preliminary amplitude set and the preliminary shielding point set are emptied, and the replacement count value is set to the initial value.

[0097] Specifically, the historical amplitude collection set, the shielding point set, the preliminary amplitude set and the preliminary shielding point set are collected once during the first running of the compressor. Thereafter, if the cumulative running time of the compressor does not reach the preset time, the compressor will shield the target frequency according to the shielding point set collected for the first time, until the cumulative running time reaches the preset time. Then, the historical amplitude collection set, the shielding point set, the preliminary amplitude set and the preliminary shielding point set are all emptied, and the replacement count value is also emptied, and the collection is re-performed. In addition, when the unit in which the compressor is located is shut down, the historical amplitude collection set, the shielding point set, the preliminary amplitude set and the preliminary shielding point set are all emptied, and the replacement count value is also emptied.

[0098] In actual application, the unit will generally be running for a long time. During this process, factors such as mechanism change of the unit, dust accumulation on the shell, and rain hitting the shell will all cause the frequency at which the compressor and the unit structure resonate to change. In order to reduce the changes caused by the above factors, the shielding point set of the running frequency of the compressor needs to be re-collected every certain period of time to ensure that the possibility of resonance between the compressor running frequency and the unit structure can be minimized, further reducing the noise and abnormal sound caused.
