Description

Technical Field

[0001] This invention relates to the field of equipment analysis technology, and more specifically, to a method and system for trend analysis of equipment operation data. Background Technology

[0002] In industrial production and equipment maintenance, the stable operation of equipment is crucial for production efficiency and safety. As equipment becomes increasingly precise and complex, problems caused by acoustic vibrations are becoming more prominent. Traditional operational data trend analysis methods often focus on single parameters, such as vibration frequency or temperature, without fully considering the coupling effect between acoustic propagation characteristics and vibration. If the vibration frequencies of different components resonate with the acoustic propagation direction, it can easily exacerbate component wear and structural damage, which is difficult to accurately identify and warn of. Furthermore, existing analysis methods often neglect the impact of regional correlations on vibration forces and structural strength, resulting in an inability to comprehensively assess equipment wear and withstand conditions. For example, the risk assessment of damage to critical components does not consider the acoustic effects of related regions, easily leading to misjudgments of equipment health, delayed maintenance decisions, and increased probability of downtime and repair costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a method and system for analyzing equipment operation data trends.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A method for analyzing equipment operation data trends, the method comprising the following steps: The vibration frequency of the equipment under test during operation and the reference acoustic propagation direction when stationary are obtained. When the vibration frequency and the reference acoustic propagation direction resonate and superimpose, the target detection component area is extracted from the equipment under test. Extract the associated component region connected to the target detection component region from the operating equipment to be tested. When the target detection component region is not connected to the auxiliary region of the operating equipment to be tested, divide the first analysis region from the associated component region. When the target detection component area is connected to the auxiliary area of ​​the operating equipment to be detected, a second analysis area is comprehensively divided from the auxiliary area; The principal actual vibration force is obtained by calculating the actual acoustic vibration force of the target detection component area based on the first and second analysis areas. The cumulative loss strength value is obtained by processing and analyzing the structural strength of the component that has been damaged by acoustic vibration force in the main actual vibration force, the target detection component area, the first analysis area and the second analysis area; The remaining withstand strength value is obtained by processing and analyzing the structural strength of the components that can be subjected to acoustic vibration forces in the target detection component area, the first analysis area, and the second analysis area. By comparing the cumulative loss strength value and the remaining tolerance strength value, we can obtain early warning information on equipment damage risk.

[0005] Preferably, when the vibration frequency resonates with the reference acoustic propagation direction, the target detection component area is extracted from the operating equipment under test, specifically including the following steps: When the vibration frequencies of different component areas in the equipment under test resonate with the reference acoustic propagation direction, the pre-analysis judgment result is output.

The secondary buffer vibration force is obtained by processing and analyzing the vibration frequency, reference acoustic propagation direction, pre-analysis phase difference, first reference acoustic intensity and vibration amplitude parameters. The principal vibration force is obtained by calculating the relationship between the initial principal vibration force and the secondary buffer vibration force.

[0009] Preferably, the vibration frequency, reference acoustic propagation direction, pre-analysis phase difference, first reference acoustic intensity, and vibration amplitude parameters are processed and analyzed to obtain the secondary buffer vibration force, specifically including the following steps: The pre-analysis phase difference is obtained by calculating the phase difference between the vibration frequency and the reference acoustic propagation direction; The acoustic vibration force of the running components in the first and second analysis regions is calculated based on the pre-analysis phase difference, the first reference acoustic intensity, and the vibration amplitude parameters to obtain the actual vibration force. The secondary buffer vibration force is determined based on the actual vibration force, which is distributed horizontally from the running component to the target detection component area in the first and second analysis areas.

[0010] Preferably, the cumulative loss strength value is obtained by processing and analyzing the structural strength of the component that has been damaged by acoustic vibration in the main actual vibration force, the target detection component area, the first analysis area, and the second analysis area. Specifically, this includes the following steps: The loss strength value is obtained by calculating the structural strength of the running components in the first and second analysis regions based on the actual vibration force. The loss strength value 2 is obtained by calculating the structural strength of the loss component in the target detection component area based on the actual vibration force. The cumulative loss intensity value is obtained by summing the first loss intensity value and the second loss intensity value.

[0011] Preferably, the remaining withstand strength value is obtained by processing and analyzing the structural strength of the target detection component area, the first analysis area, and the second analysis area that can be subjected to acoustic vibration forces. Specifically, this includes the following steps: The structural strength of the components in the first and second analysis regions is marked as the secondary reference withstand strength value. Obtain the main reference withstand strength value of the component structural strength marker in the target detection component area; The first endurance strength value is obtained by calculating the secondary reference endurance strength value and the first loss strength value. The second withstand strength value is obtained by calculating the second withstand strength value from the main reference withstand strength value and the second loss strength value; The remaining tolerance strength value is obtained by summing the first tolerance strength value and the second tolerance strength value.

[0013] An electronic device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the device operation data trend analysis method.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention divides the target detection component area into a first analysis area and a second analysis area based on the connection relationship between the target detection component area and the auxiliary area, fully considering the influence of the equipment's physical structure on acoustic vibration transmission. During actual operation, acoustic vibrations propagate along the structural connection path, and the connection state between the auxiliary area and the target component directly alters the vibration transmission method and intensity. By distinguishing and dividing the analysis areas, subsequent acoustic force calculations and strength loss analyses are deeply adapted to the actual operating conditions of the equipment. The acoustic parameters of the first and second analysis areas are integrated, taking into account the acoustic buffering and transmission effects of related areas. By integrating the loss data of the target component and related areas, the damage caused by acoustic vibration to the equipment is a long-term cumulative process that propagates and diffuses between components. This method, by accumulating the strength loss of the target component, the first analysis area, and the second analysis area, fully presents the degree of damage accumulation in the critical areas of the equipment. Equipment damage is a gradual process that develops from minor wear to failure. This method, through quantified thresholds, clearly defines the critical state from safe operation to "risk of damage," triggering timely warnings when the structural tolerance limit is reached, significantly improving the accuracy of equipment failure prevention.

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0020] Reference Figures 1-3 As shown.

[0021] The embodiments further illustrate the equipment operation data trend analysis method and system proposed in this invention.

[0022] A method for analyzing equipment operation data trends, the method comprising the following steps: The vibration frequency of the equipment under test during operation and the reference acoustic propagation direction when stationary are obtained. When the vibration frequency and the reference acoustic propagation direction resonate and superimpose, the target detection component area is extracted from the equipment under test. Extract the associated component region connected to the target detection component region from the operating equipment to be tested. When the target detection component region is not connected to the auxiliary region of the operating equipment to be tested, divide the first analysis region from the associated component region. When the target detection component area is connected to the auxiliary area of ​​the operating equipment to be detected, a second analysis area is comprehensively divided from the auxiliary area; The principal actual vibration force is obtained by calculating the actual acoustic vibration force of the target detection component area based on the first and second analysis areas. The cumulative loss strength value is obtained by processing and analyzing the structural strength of the component that has been damaged by acoustic vibration force in the main actual vibration force, the target detection component area, the first analysis area and the second analysis area; The remaining withstand strength value is obtained by processing and analyzing the structural strength of the components that can be subjected to acoustic vibration forces in the target detection component area, the first analysis area, and the second analysis area. The equipment damage risk warning information is obtained by comparing the cumulative loss strength value and the remaining tolerance strength value. When the cumulative loss strength value is equal to the remaining tolerance strength value, the equipment damage risk warning information is output.

[0023] This application aims to obtain the vibration frequency of the equipment under test during operation and the reference acoustic propagation direction when the equipment is stationary. When the vibration frequency and the reference acoustic propagation direction resonate and superimpose, the target detection component area is extracted from the equipment. Because the component is greatly affected during resonance superposition, the associated component areas connected to the target detection component area are then extracted. Different analysis areas are defined based on whether the target detection component area is connected to the equipment's auxiliary area. If it is not connected to the auxiliary area, the first analysis area is defined from the associated component area; if it is connected, the second analysis area is comprehensively defined from the auxiliary area.

[0024] The actual acoustic vibration force, or principal actual vibration force, is calculated based on the first and second analysis regions. The cumulative loss strength value is calculated by processing and analyzing the principal actual vibration force, the structural strength of the target detection component region, and the structural strength of the component already weakened by acoustic vibration forces in the first and second analysis regions. This reflects the loss already incurred by the component due to vibration. The remaining withstand strength value is obtained based on the structural strength of the target detection component region, the first analysis region, and the second analysis regions that can withstand acoustic vibration forces. This represents the remaining strength margin that the component can still withstand.

[0025] By comparing the cumulative wear and tear value with the remaining withstand strength value, a warning message about equipment damage risk is generated. When the cumulative wear and tear value equals the remaining withstand strength value, it indicates that the component is about to reach its withstand limit. At this time, a warning message about equipment damage risk is output to remind users to pay attention to the equipment status and perform timely maintenance or handling to avoid equipment damage.

[0026] When the vibration frequency resonates with the reference acoustic propagation direction, the target detection component area is extracted from the operating equipment under test, specifically including the following steps: When the vibration frequencies of different component areas in the equipment under test resonate with the reference acoustic propagation direction, the pre-analysis judgment result is output. The target detection component area is obtained by extracting the component area corresponding to the pre-analysis judgment result from the operating equipment to be tested.

[0027] This application monitors the equipment under test while it is in operation, capturing the vibration frequencies of different component areas and determining the reference acoustic propagation direction when the equipment is stationary. When a resonance superposition phenomenon is detected, caused by the interaction between the vibration frequency and the reference acoustic propagation direction of a certain component area, the application identifies this special state and outputs a pre-analysis judgment result, marking the component area where the resonance superposition occurs. Based on the pre-analysis judgment result, the application filters and extracts the corresponding component area from the numerous component areas of the operating equipment under test, identifying it as the target detection component area.

[0028] When the target detection component area is not connected to the auxiliary area of ​​the operating device to be detected, the first analysis area is delineated from the associated component area, specifically including the following steps: When the target detection component area is not connected to the auxiliary area of ​​the operating equipment to be detected; Obtain the acoustic intensity of each region in the associated component area and mark it as the first acoustic intensity value; The region of associated components whose first acoustic intensity value is equal to the preset intensity judgment threshold is divided into the first analysis region.

[0029] This application first determines the connection status between the target detection component area and the equipment auxiliary area. When it is clear that they are not connected, an acoustic intensity analysis process for the associated component area is performed. The associated component area is meticulously monitored, and acoustic intensity information for each sub-region is collected and marked as a first acoustic intensity value. These values ​​reflect the degree to which different areas of the associated component are affected by acoustic vibration. The first acoustic intensity value is compared with a preset intensity threshold, and associated component areas with equal values ​​are selected and designated as the first analysis area. The portion matching the preset acoustic intensity characteristics is located within the associated component area. Subsequent analyses of acoustic vibration forces and component structural strength loss are conducted based on this area, providing crucial regional division criteria for overall equipment operating status assessment and damage risk warning.

[0030] When the target detection component area is connected to the auxiliary area of ​​the operating equipment to be detected, a second analysis area is comprehensively divided from the auxiliary area, specifically including the following steps: When the target detection component area is connected to the auxiliary area of ​​the operating equipment to be detected; Acquire the acoustic intensity of each region in the auxiliary region and label it as the second acoustic intensity value; The auxiliary region where the second acoustic intensity value is equal to the preset intensity judgment threshold is divided into the second analysis region.

[0031] This application, when determining that the target detection component area and the auxiliary area of ​​the operating equipment under test are connected, performs acoustic intensity monitoring on the auxiliary area to obtain acoustic intensity information of each sub-region within the auxiliary area, and marks this information as a second acoustic intensity value. These values ​​are used to quantify the degree to which different parts of the auxiliary area are affected by acoustic vibration. The second acoustic intensity value is compared with a preset intensity judgment threshold, and the auxiliary area portion whose acoustic intensity value is equal to the preset threshold is selected and defined as the second analysis area. The area matching the preset acoustic intensity characteristics is extracted from the auxiliary area.

[0032] The principal actual vibration force is obtained by calculating the actual acoustic vibration force of the target detection component area based on the first and second analysis areas, specifically including the following steps: Obtain the first reference acoustic intensity and vibration amplitude parameters of the running components in the first and second analysis regions when they are stationary; Acquire the second reference acoustic intensity of the target detection component area in a static state; The initial principal vibration force is obtained by calculating the initial acoustic vibration force on the target detection component area based on the vibration amplitude parameter and the second reference acoustic intensity. The secondary buffer vibration force is obtained by processing and analyzing the vibration frequency, reference acoustic propagation direction, pre-analysis phase difference, first reference acoustic intensity and vibration amplitude parameters. The principal vibration force is obtained by calculating the relationship between the initial principal vibration force and the secondary buffer vibration force.

[0033] This application collects first reference acoustic intensity and vibration amplitude parameters of the operating component in a static state in the first and second analysis regions. The first reference acoustic intensity reflects the basic strength value of the acoustic characteristics of the component in that region when it is stationary, and the vibration amplitude parameter reflects the amplitude level of the acoustic vibration when the component is stationary. For the target detection component region, a second reference acoustic intensity is collected in its static state. The second reference acoustic intensity represents the basic acoustic strength of the target component itself when it is stationary.

[0034] The initial principal vibration force is calculated based on the collected vibration amplitude parameters and the second reference acoustic intensity to determine the initial acoustic vibration force acting on the target detection component area. The initial acoustic vibration force borne by the target component is derived based on its own static acoustic properties and the influence of vibration amplitude transmitted from the associated region.

[0035] The acoustic environment during equipment operation is complex, and the force on the target detection component area is also affected by the overall acoustic propagation characteristics. The vibration frequency is the actual operating frequency of the equipment; the reference acoustic propagation direction is the reference path of acoustic propagation when the equipment is stationary; the pre-analysis phase difference is the phase difference value generated by the interaction between the vibration frequency and the reference acoustic propagation direction; the first reference acoustic intensity is the static acoustic intensity of the first and second analysis regions; and the vibration amplitude parameter is the vibration amplitude of the first and second analysis regions. The secondary buffer vibration force is calculated by comprehensively processing these parameters.

[0036] The primary vibration force is obtained by calculating the initial primary vibration force and the secondary buffer vibration force. The initial primary vibration force is the force on the target component under ideal conditions, while the secondary buffer vibration force is the correction amount brought by the associated area in actual operation. The combination of the two can reflect the actual acoustic vibration force borne by the target detection component area in the actual operating environment of the equipment.

[0037] The secondary buffer vibration force is obtained by processing and analyzing the vibration frequency, reference acoustic propagation direction, pre-analysis phase difference, first reference acoustic intensity, and vibration amplitude parameters. This process includes the following steps: The pre-analysis phase difference is obtained by calculating the phase difference between the vibration frequency and the reference acoustic propagation direction; The acoustic vibration force of the running components in the first and second analysis regions is calculated based on the pre-analysis phase difference, the first reference acoustic intensity, and the vibration amplitude parameters to obtain the actual vibration force. The secondary buffer vibration force is determined based on the actual vibration force, which is distributed horizontally from the running component to the target detection component area in the first and second analysis areas.

[0038] This application focuses on the acoustic vibration characteristics of equipment during operation, and calculates the phase difference between the vibration frequency and the reference acoustic propagation direction to obtain the pre-analyzed phase difference. The vibration frequency generated by the equipment during operation and its reference acoustic propagation direction when stationary interact with each other, and their phase relationship affects the superposition or cancellation effect of acoustic vibrations.

[0039] The actual acoustic vibration force is calculated by measuring the pre-analysis phase difference, the first reference acoustic intensity, and the vibration amplitude parameters of the operating components in the first and second analysis regions. The pre-analysis phase difference reflects the phase relationship of the overall acoustic environment, while the first reference acoustic intensity and vibration amplitude parameters reflect the acoustic properties and vibration scale of the components in the associated region. Combining these three parameters allows for the quantification of the actual acoustic vibration force borne by the components in the associated region.

[0040] The first reference acoustic intensity represents the inherent acoustic properties of the components operating in these two regions when stationary. The vibration amplitude parameter reflects the physical amplitude of the actual vibration during component operation and is closely related to the magnitude of the acoustic vibration force. During calculation, the first reference acoustic intensity is dynamically corrected based on the pre-analyzed phase difference. For example, when the phase difference is in the 0-π range, it indicates that the acoustic vibrations will superimpose within the region, and the first reference acoustic intensity is amplified proportionally; if the phase difference is in the π-2π range, the acoustic vibrations cancel each other out, and the first reference acoustic intensity is correspondingly attenuated.

[0041] The vibration amplitude parameter utilizes the coupling relationship between mechanics and acoustics to convert the vibration amplitude into a dynamic component of the acoustic vibration force. Specifically, a larger vibration amplitude means a greater physical displacement or velocity of the component, a stronger interaction with acoustic energy, and a greater acoustic vibration force. Multiplying the vibration amplitude parameter by the corrected first reference acoustic intensity, and incorporating the influence coefficient of the pre-analysis phase difference on energy transfer, yields the secondary real vibration force experienced by the operating component in the first and second analysis regions.

[0042] Based on the analysis of the secondary vibration force, the forces dispersed horizontally from the running components in the first and second analysis regions to the target detection component region are determined, thereby identifying the secondary buffer vibration force. Because the components in the associated region, after bearing acoustic vibration forces, transmit or disperse these forces to the target detection component region through structural connections, the secondary vibration force represents the total force in the associated region. The secondary buffer vibration force dispersed horizontally to the target component is extracted from this total force. This demonstrates the indirect influence of the associated region on the acoustic force on the target detection component region and can correct the actual force calculation of the target component.

[0043] The sub-real vibration force represents the actual acoustic vibration force borne by the operating components in the first and second analysis regions, and is a key indicator reflecting the acoustic stress state in these regions. When the operating components in these regions are subjected to the sub-real vibration force, the force will be dispersed and transmitted in different directions due to the structural connections and mechanical transmission characteristics between the components.

[0044] The connection relationship and mechanical transmission path between the first and second analysis areas and the target detection component area in the equipment structure are clarified, defining the channels and methods of horizontal force transmission. Based on the actual vibration force, the secondary buffer vibration force dispersed horizontally from the running components in the first and second analysis areas to the target detection component area is determined using a mechanical analysis model. For example, if the connection between components is rigid, the force transmission loss is small, and a large proportion of the actual vibration force will be dispersed horizontally as secondary buffer vibration force; if the connection has a flexible or damped structure, the force will attenuate during transmission, and the dispersed secondary buffer vibration force will be adjusted accordingly. Using the actual vibration force as the source, and combining the mechanical transmission characteristics of the equipment structure, the force flowing horizontally to the target detection component area, i.e., the secondary buffer vibration force, is decomposed, reflecting the acoustic vibration force buffering effect of the first and second analysis areas on the target detection component area in the horizontal direction.

[0045] The cumulative loss strength value is obtained by processing and analyzing the structural strength of the components that have been damaged by acoustic vibration in the main actual vibration force, the target detection component area, the first analysis area, and the second analysis area. The specific steps include: The loss strength value is obtained by calculating the structural strength of the running components in the first and second analysis regions based on the actual vibration force. The loss strength value 2 is obtained by calculating the structural strength of the loss component in the target detection component area based on the actual vibration force. The cumulative loss intensity value is obtained by summing the first loss intensity value and the second loss intensity value.

[0046] This application first clarifies the structural strength loss caused by acoustic vibration forces in the target detection component area, the first analysis area, and the second analysis area. For the first and second analysis areas, the structural strength loss of their operating components is calculated using the actual vibration force, since the actual vibration force is the acoustic vibration force actually borne by these two areas. Based on the correlation model between force and structural strength loss in mechanics of materials (such as the fatigue damage accumulation theory, where repeated vibration forces lead to the accumulation of microscopic damage in the component structure), the actual vibration force is substituted into the calculation to obtain the loss strength value for these two areas.

[0047] For the target detection component area, the principal actual vibration force is calculated, which is the actual acoustic vibration force borne by the area. Using the correspondence between force and structural strength loss, the second loss intensity value for the target detection component area is calculated. Finally, the first and second loss intensity values ​​are added together to obtain the cumulative loss intensity value, which comprehensively reflects the total structural strength loss caused by acoustic vibration in the critical areas of the equipment.

[0048] The remaining withstand strength value is obtained by processing and analyzing the structural strength of the component that can be subjected to acoustic vibration forces in the target detection component area, the first analysis area, and the second analysis area. The specific steps include: The structural strength of the components in the first and second analysis regions is marked as the secondary reference withstand strength value. Obtain the main reference withstand strength value of the component structural strength marker in the target detection component area; The first endurance strength value is obtained by calculating the secondary reference endurance strength value and the first loss strength value. The second withstand strength value is obtained by calculating the second withstand strength value from the main reference withstand strength value and the second loss strength value; The remaining tolerance strength value is obtained by summing the first tolerance strength value and the second tolerance strength value.

[0049] This application obtains the component structural strength of the first analysis region and the second analysis region respectively and marks them as the secondary reference withstand strength value. This value represents the basic strength of the components in these two related regions that can originally withstand acoustic vibration forces. At the same time, it obtains the component structural strength of the target detection component region and marks it as the main reference withstand strength value, which is the basic strength standard of the target core component itself that can withstand acoustic vibration.

[0050] For both the first and second analysis regions, the secondary reference withstand strength value and the loss strength value are calculated to obtain the withstand strength value one. The actual remaining acoustic vibration force that the region can withstand after loss is obtained by subtracting the lost strength from the base withstand strength. For the target detection component region, the primary reference withstand strength value and the loss strength value two are calculated to obtain the withstand strength value two, thereby quantifying the remaining withstand strength of the target component.

[0051] The remaining withstand strength value is obtained by adding the first withstand strength value and the second withstand strength value. This reflects the total remaining acoustic vibration force that the critical areas of the equipment can withstand. It can then be compared with the cumulative loss strength value to determine whether the equipment faces damage risk. If the cumulative loss strength value equals the remaining withstand strength value, a damage risk warning for the equipment should be issued.

When the vibration frequency and the reference acoustic propagation direction resonate and superimpose, the target detection component area is extracted from the operating device under test. First segmentation module: Extract the associated component region connected to the target detection component region from the operating device to be tested. When the target detection component region is not connected to the auxiliary region of the operating device to be tested, segment the first analysis region from the associated component region.
