Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel wire rope flaw detection, in particular to a multifunctional modular vibration non-destructive flaw detection system and method. BACKGROUND

[0002] Steel wire rope has high strength, good toughness, fatigue resistance, wear resistance and corrosion resistance, and is widely used in lifting and hoisting, transportation and traction, bridge structure support, marine engineering, industrial machinery transmission, military aviation and entertainment facilities, etc. It is an important load-bearing and force transmission tool.

[0003] During use, the performance of the steel wire rope may be degraded due to wear, corrosion, fatigue or broken wires, etc., and there are hidden dangers. Therefore, through flaw detection, internal or surface damage can be found in time to ensure that its strength and safety meet the use requirements, thereby preventing accidents and prolonging its service life. SUMMARY

[0004] In view of the problems existing in the prior art, the purpose of the present application is to provide a multifunctional modular vibration non-destructive flaw detection system and method, which can perform non-destructive flaw detection on the steel wire rope, so as to find problems in time and solve them.

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme: a multifunctional modular vibration non-destructive flaw detection system, comprising: an acquisition module for acquiring the vibration frequency of the steel wire rope in real time and recording it for subsequent judgment process, in which the vibration frequency is used to indirectly represent the health status of the steel wire rope; a preset module for obtaining the vibration frequency of the steel wire rope in a non-destructive state through multiple detections, taking the maximum and minimum values of the obtained vibration frequencies as a standard vibration frequency range, reasonably reducing the minimum value in the standard vibration frequency range and keeping the maximum value unchanged to obtain a vibration frequency range threshold; a comparison module for comparing the vibration frequency with the vibration frequency range threshold and obtaining different responses according to the comparison result, if the vibration frequency falls within the vibration frequency range threshold, it means that the steel wire rope is within the normal range and can be used normally, if the vibration frequency is less than the minimum value of the vibration frequency range threshold, it means that the steel wire rope has been damaged to some extent, which has made the steel wire rope below the normal health state, for this case, the user is reminded to repair or replace the steel wire rope.

[0006] In some embodiments, when the vibration frequency of the steel wire rope is lower than the minimum value of the vibration frequency range threshold, the damage degree of the steel wire rope is further judged according to the vibration frequency, if the damage degree is small, the steel wire rope can be continued to be used; if the damage degree is large, repair or replacement is considered.

[0007] In some embodiments, the damage degree judgment method is to obtain the vibration frequency when the steel wire rope is about to break, denoted as vibration frequency limit, which is lower than the minimum value of the vibration frequency range threshold, and to take an intermediate value between the vibration frequency limit and the minimum value of the vibration frequency range threshold, denoted as vibration frequency boundary. When the vibration frequency of the steel wire rope is lower than the minimum value of the vibration frequency range threshold, the vibration frequency of the steel wire rope is compared with the vibration frequency boundary, and different responses are obtained according to the comparison result.

[0008] In some embodiments, if the vibration frequency of the steel wire rope is greater than the vibration frequency boundary, it indicates that the damage degree of the steel wire rope is low, and the steel wire rope can continue to be used. If the vibration frequency of the steel wire rope is less than or equal to the vibration frequency boundary, the vibration frequency of the steel wire rope is compared with the vibration frequency limit, and different responses are obtained according to the comparison result.

[0009] In some embodiments, if the vibration frequency of the steel wire rope is greater than the vibration frequency limit, it indicates that the damage degree of the steel wire rope is high. In this case, the system issues a warning to remind the user that the damage degree of the steel wire rope is high, and suggests maintenance or replacement.

[0010] In some embodiments, when the vibration frequency of the steel wire rope is less than or equal to the vibration frequency boundary but greater than the vibration frequency limit, if the user does not choose to replace or maintain but chooses to continue to use, the system predicts the time when the steel wire rope is about to break, and informs the user of the time.

[0011] In some embodiments, the prediction time is obtained by the following method. When the vibration frequency of the steel wire rope is greater than the vibration frequency limit, the time when the steel wire rope has been working is obtained. For the standard vibration frequency range obtained in the preset module, an intermediate value is taken as an initial vibration frequency. The initial vibration frequency is subtracted from the vibration frequency at this time to obtain a decreased vibration frequency. The decreased vibration frequency is divided by the time when the steel wire rope has been working to obtain an average decrease value. Based on this, the remaining decreaseable vibration frequency is obtained by subtracting the vibration frequency limit when the steel wire rope is about to break from the vibration frequency at this time. The remaining decreaseable vibration frequency is divided by the average decrease value to obtain a theoretical time, which is the theoretical working time of the steel wire rope remaining before it is about to break when the user chooses to continue to use.

[0012] In some embodiments, the deviation of the theoretical time is corrected by introducing a dynamic vibration frequency correction coefficient or manually shortening the theoretical time by the user.

[0013] The present application also provides the following technical solutions:

[0014] The application further provides a multifunctional modular vibration nondestructive testing method, which firstly acquires the vibration frequency of the steel wire rope in real time and records the vibration frequency for subsequent judgment process, and indirectly represents the health state of the steel wire rope by using the vibration frequency in the judgment process; secondly, the vibration frequency of the steel wire rope in the nondestructive state is acquired through multiple detections, the maximum value and the minimum value of the vibration frequency acquired multiple times are taken as the standard vibration frequency range, the minimum value in the standard vibration frequency range is reasonably reduced, the maximum value is unchanged, and the vibration frequency range threshold is obtained; finally, the vibration frequency and the vibration frequency range threshold are compared, and different responses are obtained according to the comparison result, if the vibration frequency falls into the vibration frequency range threshold, it indicates that the steel wire rope is in the normal range and can be normally used, if the vibration frequency is less than the minimum value of the vibration frequency range threshold, it indicates that the steel wire rope has a certain damage, and the damage has made the steel wire rope lower than the normal health state, for this case, the user is reminded to maintain or replace the steel wire rope.

[0015] The application further provides a computer readable storage medium, which stores a computer program, and the computer program is executed by a processor to realize the multifunctional modular vibration nondestructive testing system.

[0016] Compared with the prior art, the technical scheme provided by the application has the following beneficial effects:

[0017] Firstly, in the application, the vibration frequency and the vibration frequency range threshold are compared, if the vibration frequency is within the vibration frequency range threshold, it indicates that the steel wire rope is in the normal range and can be normally used, if the vibration frequency is lower than the minimum value of the vibration frequency range threshold, it indicates that the steel wire rope has a certain damage, thus, whether the steel wire rope is damaged can be directly obtained by analyzing the vibration frequency.

[0018] Secondly, in the application, when the steel wire rope has a certain damage, i.e., the vibration frequency is lower than the minimum value of the vibration frequency range threshold, the damage degree is further detected, if the vibration frequency of the steel wire rope is greater than the vibration frequency limit, it indicates that the damage degree of the steel wire rope is low and the steel wire rope can be continuously used, if the vibration frequency of the steel wire rope is less than or equal to the vibration frequency limit, the vibration frequency of the steel wire rope is compared with the vibration frequency limit, if the vibration frequency of the steel wire rope is greater than the vibration frequency limit, it indicates that the damage degree of the steel wire rope is high, in this case, the system issues a warning and reminds the user to repair or replace the steel wire rope, if the vibration frequency is less than or equal to the vibration frequency limit, it indicates that the steel wire rope is about to break, in this case, the system stops working and requires to be repaired or replaced, thus, not only whether the steel wire rope can be used can be judged according to the damage degree, but also the user is provided with the right to choose when the steel wire rope is seriously damaged, so that the user can choose according to the actual situation.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0022] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0023] The multifunctional modular vibration nondestructive testing system provided by the present application, as shown in Figure 1 and Figure 2 , comprises:

[0024] The acquisition module, in which the steel wire is affected by different loads and external forces during use, generates vibration characteristics, and the sensor performs nondestructive testing and detection on the steel wire to obtain the vibration frequency generated by the steel wire when vibrating. By analyzing the vibration frequency, it can be determined whether the steel wire is damaged. Because the complete steel wire has high stiffness and structural stability, its vibration frequency is relatively stable, and its vibration frequency is mainly determined by the material properties, length, tension and other factors of the steel wire. Damage will weaken the stiffness and strength of the steel wire, and the damaged part will increase the flexibility of the steel wire in the local area, thereby changing the vibration characteristics of the steel wire, which usually causes the vibration frequency to change, especially when the damage is serious, the frequency will decrease. And because this vibration detection does not contact the steel wire and does not damage it, it not only can identify potential damage or abnormalities, but also has the characteristics of nondestructive, real-time and high efficiency.

[0025] The preset module, in which the vibration frequency of the steel wire rope in the intact state is obtained according to the parameter information and the load information of the steel wire rope. The intact steel wire rope has high rigidity and structural stability, so its vibration frequency is relatively stable, but its vibration frequency is usually not a fixed value, but within a fixed range. In order to obtain this vibration range, the steel wire rope is simulated in the experimental condition, and the vibration simulation is carried out. After multiple times, a plurality of vibration frequency ranges are obtained. In these frequency ranges, the maximum value and the minimum value are taken as the standard vibration frequency range. This standard vibration frequency range is the vibration frequency range of the intact steel wire rope. After being used for a period of time, there will be normal wear and tear. Considering that normal wear and tear does not affect use, the minimum value in the standard vibration frequency range is reasonably reduced by a certain value, and the maximum value remains unchanged, which is used as the vibration frequency range threshold of the steel wire rope that can be normally used.

[0026] The comparison module, in which the obtained vibration frequency of the steel wire rope is compared with the vibration frequency range threshold, and different responses are obtained according to the comparison result. If the vibration frequency falls within the vibration frequency range threshold, it means that the steel wire rope is within the normal range and can be normally used. If the vibration frequency is less than the minimum value of the vibration frequency range threshold, it means that the steel wire rope has been damaged to a certain extent. This damage has made the steel wire rope below the normal healthy state. For this case, the user is reminded to repair or replace the steel wire rope. It is worth mentioning that when the steel wire rope is damaged, its vibration frequency usually has two performance conditions, one is that the vibration frequency is reduced, and the other is that the vibration frequency is abnormal. When the vibration frequency is abnormal, this vibration frequency may never have appeared, and there is no comparison standard. However, because damage has occurred, even if the vibration frequency is abnormal, this abnormal vibration frequency must be lower than the vibration frequency range, and cannot be higher than the vibration frequency range threshold. Therefore, no matter which case is, the vibration frequency of the damaged steel wire rope must be lower than the vibration frequency range threshold, so in the above process, as long as the vibration frequency is lower than the minimum value of the vibration frequency range threshold, the steel wire rope has been damaged to a certain extent. Therefore, the above method can enable the system to stably judge the problems of the steel wire rope and reduce the possibility of misjudgment. Because the damage of the steel wire rope can be recognized whether the vibration frequency is reduced or abnormal, through this method, the reliability and practicality of the system can be significantly improved, and the safe use and early maintenance of the steel wire rope can be ensured.

[0027] In general, the vibration non-destructive testing system determines whether the steel wire rope is damaged by monitoring the vibration frequency of the steel wire rope in real time during use. The system consists of an acquisition module, a preset module, and a comparison module. The acquisition module captures the vibration frequency of the steel wire rope through sensors and analyzes its changes to identify whether the steel wire rope is damaged. A complete steel wire rope has a relatively stable vibration frequency due to its high stiffness and structural stability, which is mainly affected by factors such as material, length, and tension. Damage to the steel wire rope can cause a decrease in stiffness and an increase in local flexibility, resulting in a decrease in frequency. The preset module determines the vibration frequency range of the steel wire rope during normal use based on the working parameters of the steel wire rope (such as load and tension) through experiments and vibration simulation, and adjusts the minimum value reasonably to accommodate normal wear and tear to obtain the vibration frequency range threshold. The comparison module compares the acquired vibration frequency with the preset vibration frequency range threshold. If the vibration frequency is within the vibration frequency range threshold, the steel wire rope is normal; if it is lower than the minimum value of the range threshold, the steel wire rope has been damaged. Whether the vibration frequency decreases or an abnormal vibration frequency appears, the vibration frequency after damage must be lower than the minimum value of the vibration frequency range threshold, ensuring that the system can accurately identify the damage to the steel wire rope and reduce false positives. Through this method, the system can achieve non-destructive, real-time, and efficient detection, improving the safety and reliability of the steel wire rope in use.

[0028] It is worth mentioning that, because the steel wire rope is subjected to damage detection during its previous daily use, the data recorded during previous damage detection forms historical data, which can be used to distinguish whether the vibration frequency is normal or abnormal if it is lower than the minimum value of the vibration frequency range threshold. If a certain vibration frequency has never appeared during previous use, it can be considered abnormal, rather than just lower than the minimum value of the vibration frequency range threshold. Of course, time-domain analysis of the vibration signal waveform can also be used to judge the abnormal vibration frequency, as abnormal frequencies usually exhibit sudden, irregular, or irregular waveforms, while normal frequency decreases exhibit gradual, linear, or smooth waveform changes. However, this method requires further obtaining the vibration waveform characteristics of the steel wire rope, which is more complex than the vibration frequency analyzed in this application, so it is only for reference and not for specific analysis. In this application, historical data can be used to determine whether the vibration frequency is abnormal.

[0029] According to the above, when the vibration frequency of the steel wire rope is lower than the minimum value of the vibration frequency range threshold, it indicates that the steel wire rope is damaged. However, the damage of the steel wire rope does not necessarily mean that it cannot be used any more. Because the degree of damage can be large or small, if the damage is within an acceptable range, the steel wire rope can still be used even if it is damaged. In practical application, a damaged steel wire rope only has weakened strength, but has not broken. As long as it has not broken, it can still be used. Therefore, in the above, when the vibration frequency of the steel wire rope is lower than the minimum value of the vibration frequency range threshold, the degree of damage of the steel wire rope can be further judged according to the vibration frequency. If the degree of damage is small, it can be used; if the degree of damage is large, it is considered for repair or replacement. In this way, the waste of the steel wire rope can be avoided, and it can be used as much as possible. Specifically, the vibration frequency when the steel wire rope is about to break is obtained, which is denoted as vibration frequency limit, which is lower than the minimum value of the vibration frequency range threshold. At the same time, an intermediate value between the vibration frequency limit and the minimum value of the vibration frequency range threshold is taken, which is denoted as vibration frequency limit. When the vibration frequency of the steel wire rope is lower than the minimum value of the vibration frequency range threshold, the vibration frequency of the steel wire rope is compared with the vibration frequency limit, and different responses are obtained according to the comparison result. If the vibration frequency of the steel wire rope is greater than the vibration frequency limit, it indicates that the degree of damage of the steel wire rope is low, and it can be used. If the vibration frequency of the steel wire rope is less than or equal to the vibration frequency limit, the vibration frequency of the steel wire rope is compared with the vibration frequency limit, and different responses are obtained according to the comparison result. If the vibration frequency of the steel wire rope is greater than the vibration frequency limit, it indicates that the degree of damage of the steel wire rope is high, but it is not about to break. In this case, the system issues a warning to remind the user that the degree of damage of the steel wire rope is high, and suggests repair or replacement. However, the user can choose whether to repair or replace or continue to use according to his actual situation. Because in some scenarios, even if the steel wire rope breaks, it will not have a great impact, for example, it is only used temporarily for simple binding. In this case, it is likely to find an old steel wire rope for use. Under this condition, even if the steel wire rope breaks, it can be replaced again. Therefore, when the vibration frequency is greater than the vibration frequency limit but less than or equal to the vibration frequency limit, the system only issues a warning and suggests repair or replacement, but does not stop working compulsorily, leaving the choice to the user. If the vibration frequency is less than or equal to the vibration frequency limit, it indicates that the steel wire rope is about to break. In this case, the system stops working and requires repair or replacement. Because when it is about to break, even if the user does not care about the impact of the breakage, the use of the steel wire rope has lost its meaning because the steel wire rope cannot be used. In this way, by introducing the vibration frequency limit and the vibration frequency limit, a more detailed judgment basis is provided for the damage assessment of the steel wire rope.Firstly, the vibration frequency limit represents the vibration frequency when the steel wire rope is about to break, and the vibration frequency boundary is an intermediate value between the vibration frequency limit and the minimum value of the vibration frequency range threshold. The system will take different measures according to the comparison of the actual vibration frequency of the steel wire rope with the two boundaries. Specifically, when the vibration frequency of the steel wire rope is greater than the vibration frequency boundary, it indicates that the damage is slight and can continue to be used. If the vibration frequency is less than or equal to the vibration frequency boundary, the system further compares it with the vibration frequency limit. If the vibration frequency is greater than the vibration frequency limit, the damage is high, but it is not close to breaking, the system will issue a warning and suggest that the user repair or replace, but it is not forced to stop using, giving the user the choice space according to the scene needs. If the vibration frequency is less than or equal to the vibration frequency limit, the steel wire rope has approached breaking, and the system will be forced to stop working and require repair or replacement, because the steel wire rope cannot continue to be used at this time. This scheme can provide flexible response mode according to the damage degree of the steel wire rope, not only guaranteeing safety, but also allowing users to make decisions according to specific circumstances, thereby effectively avoiding resource waste and improving the use efficiency of the steel wire rope.

[0030] In the above process, when the vibration frequency of the steel wire rope is less than or equal to the vibration frequency limit, but greater than the vibration frequency limit, if the user does not choose to replace or repair, but chooses to continue using. The system predicts the time when the steel wire rope is about to break, and informs the user of the time. Because the steel wire rope at this time is already in a high degree of damage, although it is not close to breaking, but choose to continue to use, eventually is close to breaking, give a rough time of the distance to breaking can let the user prepare in advance, prevent the sudden, make the work in progress. The specific way is: when the vibration frequency of the steel wire rope is greater than the vibration frequency limit, get the time the steel wire rope has worked. At the same time, for the standard vibration frequency range obtained in the preset module, take the middle value as the initial vibration frequency, the initial vibration frequency minus the vibration frequency at this time to get the vibration frequency that has fallen, the vibration frequency that has fallen divided by the time that has worked to get the average falling value. Based on this, the vibration frequency at this time minus the vibration frequency limit when the steel wire rope is about to break to get the remaining vibration frequency that can be reduced, the remaining vibration frequency that can be reduced divided by the average falling value to get the theoretical time, the theoretical time is the theoretical working time of the steel wire rope remaining before breaking when the user chooses to continue using. Since the standard vibration frequency range takes the middle value, which is greater than the minimum value of the standard vibration frequency range, therefore, for the final theoretical time, there may be some impact. If the initial vibration frequency of the undamaged steel wire rope starts from near the minimum value of the standard vibration frequency range, the predicted theoretical time will be biased. If the initial vibration frequency of the undamaged steel wire rope starts from near the maximum value of the standard vibration frequency range, the theoretical time obtained will also be biased. In order to optimize this deviation, a dynamic vibration frequency correction coefficient can be introduced, which will be dynamically adjusted according to the actual working environment, initial state and possible changes during use of the steel wire rope, so as to ensure that the prediction result is more representative and accurate. Specifically, the dynamic vibration frequency correction coefficient can be introduced and applied through the following steps: first, based on the use environment and historical data of the steel wire rope, an initial correction coefficient is determined. For example, the working environment of the steel wire rope (such as temperature, humidity, load, etc.) may affect its initial vibration frequency. In an extreme environment, the vibration frequency of the steel wire rope may start from the minimum value of the standard vibration frequency range, while in a relatively mild environment, the vibration frequency of the steel wire rope may be closer to the middle value of the standard range. Therefore, by monitoring the initial vibration frequency of the steel wire rope and the environmental parameters, a preliminary correction coefficient can be set for each steel wire rope, which determines the dynamic adjustment range of the vibration frequency. Secondly, as the use time of the steel wire rope increases, the system will monitor the vibration frequency of the steel wire rope in real time, and correct it according to the vibration frequency and the expected falling mode.For example, when the rate of decline in the vibration frequency of the steel wire rope exceeds expectations, the dynamic correction factor is automatically increased, indicating that the degree of damage to the steel wire rope is increasing and the expected remaining service time is shortened. When the rate of decline in the vibration frequency is slower, the correction factor is reduced, indicating that the steel wire rope remains in good working condition and has a longer remaining service time. This process can be achieved by continuously updating the vibration frequency and working time data, and each time the data is updated, the correction factor will be automatically adjusted according to the actual situation. In addition, the dynamic vibration frequency correction factor can also take into account other external factors, such as the performance of the steel wire rope under different loads, working cycles, and working conditions. For example, if the steel wire rope is working under high load, the rate of decline in the vibration frequency will accelerate, so the correction factor needs to be adjusted to reflect the impact of load on the vibration frequency. In this way, the system can automatically adjust the correction factor in each use cycle, making the damage assessment and remaining working time prediction of the steel wire rope more in line with the actual working conditions. Of course, the introduction of this dynamic vibration frequency correction factor will make the operation more complex, so this method provides users with an option, and users can choose whether to adopt it according to the actual application situation. If this method is not adopted, the most direct method to optimize the deviation is to manually reduce the theoretical time, for example, reducing the theoretical time by 10%, 20%, etc.
