Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of mining machinery, and particularly relates to a method, device, storage medium and program product for monitoring and predicting the operation of components. Background Art
[0002] When mining machinery is in operation, each component is excited by the engine to generate structural vibration, and the magnitude of the vibration response will fluctuate with changes in engine speed, working load, and road surface excitation, ultimately leading to vibration fatigue damage to the component structure.
[0003] Currently, in order to avoid accidents caused by vibration fatigue damage of components, vibration simulation tests are usually carried out on components, and a reference duration is obtained, that is, the service life of the component for the operator's reference, so that the operator can replace the component in time before it reaches the service life. However, since the vibration conditions of the component during actual use may be different from those in the vibration simulation test, the reference duration is only a theoretical value, and there is a deviation from the actual duration that the component can be used. If the reference duration is longer than the actual use duration, it may lead to failures or accidents due to the failure to replace the component in time. If the reference duration is shorter than the actual use duration, the component will be replaced in advance, resulting in waste of resources. Summary of the Invention
[0004] The present invention aims to solve at least one of the technical problems in the related art to some extent.
[0005] The present invention provides a method for monitoring and predicting the operation of components, characterized by including:
[0006] Monitoring the vibration excitation of the component and obtaining the calculated vibration spectrum and single cycle duration;
[0007] Calculating the remaining duration based on the single cycle duration;
[0008] If the remaining duration is not greater than the set threshold, outputting a time warning prompt message for the component;
[0009] If the remaining duration is greater than the set threshold, repeating the above steps.
[0010] This method monitors the vibration excitation of the component, and at the same time considers the influence of the full-frequency vibration excitation, calculates and evaluates the remaining duration of the component in real time and gives feedback, so as to remind the operator to timely discover the components that need to be repaired or replaced, which is beneficial to avoiding failures or accidents caused by sudden failure of components, reducing the incidence of major failures, and improving the operation efficiency of the vehicle.
[0011] Meanwhile, through the above method, the operator can perform on-demand maintenance of components based on the prediction results of the remaining duration, avoiding over-maintenance or under-maintenance in regular maintenance, thereby reducing maintenance costs, facilitating accurate prediction of the lifespan of components, avoiding premature replacement of components, and reducing resource waste.
[0012] As an alternative, obtaining the calculated vibration spectrum and the single-cycle duration includes:
[0013] Obtain the real-time vibration excitation data of the component;
[0014] Process the vibration excitation data to obtain the actual vibration spectrum of a single-cycle working condition;
[0015] Based on the reference vibration spectrum, perform data processing on the actual vibration spectrum to obtain the calculated vibration spectrum and the single-cycle duration.
[0016] Since the vibration of mining machinery under actual working conditions may differ from the reference vibration spectrum, this method performs data processing on the actual vibration spectrum to obtain the calculated vibration spectrum and the single-cycle duration, enabling the calculated vibration spectrum to have the same benchmark as the reference vibration spectrum for comparative calculation, which is conducive to improving the reliability of subsequent calculation of the remaining duration and warning prompts.
[0017] As an alternative, performing data processing on the actual vibration spectrum based on the reference vibration spectrum includes:
[0018] Perform acceleration or deceleration processing on the actual vibration spectrum to the same level as the reference vibration spectrum.
[0019] This method can, through the measurement results under a single-cycle working condition, obtain the same area as the reference vibration spectrum after acceleration processing, so that the calculated vibration spectrum after data processing can be comparable to the reference vibration spectrum, which is conducive to improving the accuracy, precision, and efficiency of calculating the remaining duration.
[0020] As an alternative, calculating the remaining duration includes:
[0021] Accumulate the single-cycle durations obtained for each single-cycle working condition to obtain the calculated duration;
[0022] The ratio of the difference between the reference duration of the component and the calculated duration to the reference duration is the remaining duration.
[0023] After data processing for each cycle working condition, this method accumulates the single-cycle durations of each single-cycle working condition according to the real-time monitoring data, which is conducive to ensuring the tight correlation between the calculated duration used to calculate the remaining duration and the actual working conditions, and is conducive to improving the accuracy of the calculation results.
[0024] As an alternative, after replacing the component, the real-time vibration excitation data is reset.
[0025] This method avoids the interference of the vibration data of the old components, ensures that the vibration characteristics of the new components are accurately recorded, that is, eliminates the influence of historical data. Resetting helps to recalibrate the sensors and measurement equipment, thereby improving the data acquisition accuracy. At the same time, the vibration characteristics of the new components may be different from those of the old components. Resetting the data enables the system to quickly adapt to the new characteristics, avoids the interference of the old data on the new data, reduces error accumulation, is beneficial to optimizing the operating state, and improves the system stability.
[0026] As an alternative, the method for obtaining the reference vibration spectrum and the reference duration includes:
[0027] Obtain a random vibration excitation spectrum;
[0028] Combined with the design time requirement and the durability assessment boundary requirement, obtain the reference vibration spectrum and the reference duration.
[0029] This method is beneficial to ensuring that the test conditions are consistent with the actual working conditions, that is, truly reflecting the vibration excitation spectrum of the component and the actual operating environment of the mining machinery, improving the reliability of the test, and is beneficial to improving the reliability of the calculated duration and the remaining duration obtained based on the reference vibration spectrum and the reference duration.
[0030] As an alternative, obtaining the random vibration excitation spectrum through the actual operating condition data of the vehicle or reference experience is beneficial to accurately simulating the vibration environment of the component during actual use, and then improving the reliability of the calculated duration and the remaining duration obtained based on the reference vibration spectrum and the reference duration.

Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0051] In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or components inherent to these processes, methods, products, or devices.
[0052] As Figure 1 shown, this embodiment provides a method for monitoring and predicting the operation of parts, and the method includes:
[0053] S100, monitoring the vibration excitation of the parts and obtaining the calculated vibration spectrum and single-cycle duration;
[0054] S200, calculating the remaining duration based on the single-cycle duration;
[0055] S300, if the remaining duration is not greater than the set threshold, outputting a time warning prompt message for the parts;
[0056] S400, if the remaining duration is greater than the set threshold, repeating the above steps. The above steps here are the steps of S100 - S400.
[0057] This method monitors the vibration excitation of the parts, and at the same time considers the influence of the full-band vibration excitation, calculates and evaluates the remaining duration of the parts in real time and gives feedback, so as to remind the operator to timely discover the parts that need to be repaired or replaced, which is beneficial to avoiding faults or accidents caused by sudden failure of the parts, reducing the incidence of major faults, and achieving the purpose of improving the vehicle operation efficiency.
[0058] At the same time, through the above method, the operator can perform on-demand maintenance on the parts based on the prediction result of the remaining duration, avoid over-maintenance or under-maintenance in regular maintenance, thereby reducing the maintenance cost, being beneficial to accurately predicting the life of the parts, avoiding premature replacement of the parts, and reducing resource waste.
[0059] Among them, this embodiment is applicable to the application scenario of mining machinery. When mining machinery operates in a single mining area, the working conditions are simple and cyclic. At this time, the single-cycle working condition can be used as a data processing unit for calculation. Exemplarily, the single-cycle working condition of mining machinery in a single mining area can be "empty vehicle - waiting - loading - loading - unloading - empty vehicle", "no-load - excavation - loading - unloading - no-load", etc. This embodiment does not limit the specific content of the single-cycle working condition.
[0060] Exemplarily, the way to obtain the vibration excitation can be to detect the vibration excitation of the component parts by setting vibration sensors. If the component parts are assembly component parts such as superchargers, pumps, and filters, the vibration sensors can be set at the locations with high structural stiffness on the outer side of the geometric models of the assembly component parts such as superchargers, pumps, and filters, such as the side or intermediate body position of the compressor housing of the supercharger, and the intermediate position of the housing of the filter. If the component part is a pipeline, the vibration sensor can also be placed at the position with large vibration response based on the simulation results or previous test experience. For example, it can be placed at the intermediate position between the joint and the bracket of the pipeline. If the component part is a plate, the vibration sensor is usually set at the intermediate position.
[0061] In this embodiment, the calculated vibration spectrum is the vibration spectrum obtained by processing the vibration excitation data for calculating the single-cycle duration, and is named the calculated vibration spectrum in this embodiment. Optionally, the calculated vibration spectrum can be the vibration power spectral density, that is, the vibration PSD spectrum.
[0062] As an alternative solution, as Figure 2 shown, in step S100, obtaining the calculated vibration spectrum and the single-cycle duration includes:
[0063] S110, obtaining the real-time vibration excitation data of the component parts;
[0064] S120, processing the vibration excitation data to obtain the actual vibration spectrum of the single-cycle working condition;
[0065] S130, performing data processing on the actual vibration spectrum based on the reference vibration spectrum to obtain the calculated vibration spectrum and the single-cycle duration.
[0066] Since there may be differences between the vibration of the mining machinery under the actual working conditions and the reference vibration spectrum, this method processes the actual vibration spectrum to obtain the calculated vibration spectrum and the single-cycle duration, so that the calculated vibration spectrum and the reference vibration spectrum have the same benchmark for comparative calculation, which is beneficial to improving the reliability of subsequent calculation of the remaining duration and early warning prompts.
[0067] For example, obtaining the actual vibration spectrum by processing vibration excitation data can be achieved through data processing, preprocessing, Fourier transform, and spectral analysis. Among them, data preprocessing includes denoising, detrending, and segmentation. Denoising uses filters to remove high-frequency noise or low-frequency drift. Detrending is to eliminate the linear or nonlinear trend in the signal. Segmentation is to divide the signal into several segments for subsequent analysis. Then, perform Fourier transform on the preprocessed signal to convert the time-domain signal into a frequency-domain signal and obtain the spectrum. The spectral analysis process includes the amplitude spectrum and the phase spectrum. The amplitude spectrum is used to calculate the amplitude of the spectrum, representing the intensity of each frequency component. The phase spectrum is used to calculate the phase of the spectrum, representing the time delay of each frequency component. This process is only an example of the process of obtaining the actual vibration spectrum by processing vibration excitation data and does not limit this embodiment.
[0068] Specifically, data processing of the actual vibration spectrum based on the reference vibration spectrum includes:
[0069] Performing acceleration or deceleration processing on the actual vibration spectrum to the same level as the reference vibration spectrum.
[0070] Among them, the same level can be the same area. Exemplarily, acceleration processing is achieved by increasing the vibration frequency, making the frequency of the actual vibration spectrum higher than that of the reference vibration spectrum. Specifically, it can be achieved by compressing the time axis or expanding the frequency axis. Acceleration processing is beneficial to improving efficiency and is suitable for simulating high-frequency environments. The deceleration processing method is to lower the vibration frequency, making the frequency of the actual vibration spectrum lower than that of the reference vibration spectrum. The specific methods include expanding the time axis or compressing the frequency axis. Deceleration processing is beneficial to enhancing detailed analysis and is suitable for simulating low-frequency environments.
[0071] This method can calculate the time under the premise of ensuring damage by improving vibration through the measurement results under a single-cycle working condition. Among them, the methods of improving vibration include increasing vibration energy or increasing the spectral area. In this embodiment, after acceleration processing, the same area as the reference vibration spectrum is obtained, so that the calculated vibration spectrum after data processing has comparability with the reference vibration spectrum, which is beneficial to improving the accuracy, precision, and efficiency of calculating the remaining duration.
[0072] Exemplarily, there are two methods to perform acceleration or deceleration processing on the actual vibration spectrum to the same level as the reference vibration spectrum, namely time-domain resampling and frequency-domain scaling. Time-domain resampling includes three steps: determining the scaling factor, resampling the signal, and adjusting the sampling rate. Frequency-domain scaling includes three steps: calculating the Fourier transform of the actual vibration spectrum, scaling the frequency axis, and performing inverse Fourier transform. The above process is only an example of the process of performing acceleration or deceleration processing on the actual vibration spectrum to the same level as the reference vibration spectrum and does not limit this embodiment.
[0073] Preferably, in this embodiment, the actual vibration spectrum is mainly processed by acceleration to the same level as the area of the reference vibration spectrum.
[0074] As an alternative solution, in step S200, calculating the remaining duration includes:
[0075] S210, accumulating the single-cycle duration obtained for each single-cycle working condition to obtain a calculated duration;
[0076] S220, the ratio of the difference between the reference duration of the component and the calculated duration to the reference duration is the remaining duration.
[0077] The single-cycle duration after data processing is the time of one cycle of work. It can be understood that after the component is installed and the mining machinery starts running for the first time, the vibration sensor starts to collect information.
[0078] After data processing:
[0079] Let the single-cycle duration for completing the first cycle of working conditions be set as T 1 ;
[0080] Let the single-cycle duration for completing the second cycle of working conditions be set as T 2 ;
[0081] ……
[0082] Let the single-cycle duration for completing the Nth cycle of working conditions be T N .
[0083] Let the calculated duration be Tx, then in step S210:
[0084] Tx = T 1 + T 2 + …… + T N .
[0085] Let the remaining duration be Ts and the reference duration be Tc, then in step S220:
[0086]
[0087] The operator sets a set threshold according to the safety factor requirements. Exemplarily, the set threshold in this embodiment is 1%. When the calculated remaining duration is not greater than 1%, it indicates that the use of this component is approaching the theoretical reference duration, and a time warning prompt message for the component needs to be output so that the operator can repair or replace the corresponding component in time. Of course, in other embodiments, the set threshold can also be 2%, 3% or other values.
[0088] Among them, the reference duration is the duration that the component can be used under theoretical conditions. In this embodiment, the duration can be measured in any way that can calculate time, such as hours, days, etc., and this embodiment does not limit this.
[0089] In this embodiment, the remaining duration is the proportion of the remaining duration relative to the reference duration under theory. In other embodiments, the remaining duration can also be a specific duration in hours or days.
[0090] After the method processes the data for each cyclic working condition, it accumulates the single-cycle duration of each single cyclic working condition according to the real-time monitoring data, which is beneficial to ensuring the tight association between the calculation duration used to calculate the remaining duration and the actual working conditions, and is beneficial to improving the accuracy of the calculation results.
[0091] As an alternative solution, the operator will replace the component after receiving the time warning prompt information of the component. After replacing the component, the real-time vibration excitation data is reset, avoiding the interference of the vibration data of the old component, ensuring that the vibration characteristics of the new component are accurately recorded, that is, eliminating the influence of historical data. The reset helps to recalibrate the sensors and measurement equipment, thereby improving the data acquisition accuracy. At the same time, the vibration characteristics of the new component may be different from those of the old component. Resetting the data enables the system to quickly adapt to the new characteristics, avoiding the interference of the old data on the new data, reducing error accumulation, being beneficial to optimizing the operating state, and enhancing the system stability.
[0092] In this embodiment, the reference vibration spectrum and the reference duration are parameters preset in the equipment before the mining machinery leaves the factory.
[0093] As an alternative solution, the methods for obtaining the reference vibration spectrum and the reference duration in this embodiment include:
[0094] Obtain the random vibration excitation spectrum;
[0095] Combined with the design time requirements and the durability assessment boundary requirements, obtain the reference vibration spectrum and the reference duration.
[0096] This method is beneficial to ensuring that the test conditions are consistent with the actual working conditions, that is, truly reflecting the vibration excitation spectrum of the component and the actual operating environment of the mining machinery, enhancing the reliability of the test, and being beneficial to improving the reliability of the calculation duration and the remaining duration obtained based on the reference vibration spectrum and the reference duration.
[0097] By means of the accelerated vibration test, simulating the influence of long-term vibration on the component is beneficial to shortening the development cycle.
[0098] Among them, the design time requirement refers to the expected service life of the component in the vibration environment, such as the number of hours or cycles. The durability assessment boundary requirement stipulates the vibration intensity and duration of the assessment, through the safety factor or the accelerated test requirement. The reference spectrum in this embodiment is the durability assessment spectrum value after durability assessment. This method obtains the reference spectrum through the calculation of the acceleration factor based on the data of a single cycle condition or several cycle conditions. Among them, according to the designed life and test time, the acceleration factor is determined to shorten the test time.
[0099] Furthermore, obtaining the random vibration excitation spectrum through the actual operating condition data of the vehicle or reference experience is beneficial to accurately simulate the vibration environment of the component during actual use, thereby improving the reliability of the calculated duration and the remaining duration obtained based on the reference vibration spectrum and the reference duration.
