Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of steel wire rope detection, and in particular to an AI nondestructive flaw detection system and method for an eddy current steel wire rope core conveyor belt. Background Art
[0002] The core of the eddy current steel cord conveyor belt is composed of multiple steel cords, which are usually made of high-strength steel and have good tensile strength, fatigue resistance and wear resistance. The curling and weaving of the steel cords can evenly distribute the load over the entire length of the conveyor belt, avoiding damage caused by excessive local loads. The eddy current effect refers to the design of the steel cord core, through the reasonable arrangement and weaving of the steel cords, so that its load-bearing capacity is enhanced. This structure causes the belt body to produce a certain vibration and rotation effect during operation, thereby improving the stability and tensile strength of the belt body.
[0003] The carrying capacity of the wire rope determines the load capacity of the conveyor belt. When the wire rope is damaged, the conveyor belt is likely to fail to work properly. Therefore, it is necessary to detect the health status of the wire rope. Because the health status detection can detect problems in advance before the conveyor belt fails to work, so that the staff can predict and prepare for the problems in advance, and prevent the conveyor belt from being damaged suddenly and affecting normal operation. Summary of the invention
[0004] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide an AI non-destructive flaw detection system and method for an eddy current steel wire rope core conveyor belt, so as to detect the health status and damage condition of the eddy current steel wire rope in the conveyor belt, discover and solve problems in advance, and avoid affecting normal operation.
[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an AI nondestructive flaw detection system for eddy current steel wire rope core conveyor belts, comprising: a steel wire rope parameter acquisition module, which is used to obtain the number of steel wire ropes in the conveyor belt and the number of steel wire ropes with cracks in the steel wire ropes, and the number of intact steel wire ropes is obtained by subtracting the number of cracked steel wire ropes from the number of steel wire ropes; a steel wire rope threshold setting module, which is used to set a threshold value for the number of intact steel wire ropes, and the threshold value for the number of intact steel wire ropes represents the standard for the number of intact steel wire ropes required for the conveyor belt to bear the load and work normally; a steel wire rope parameter comparison and response module, which is used to compare the number of intact steel wire ropes with the threshold value for the number of intact steel wire ropes. If the number of intact steel wire ropes of the conveyor belt is greater than or equal to the set threshold value for the number of intact steel wire ropes, it means that the conveyor belt can bear enough load and has the ability to operate normally. The system will allow it to continue to be used and perform status monitoring when necessary. If the number of intact steel wire ropes is lower than the set threshold value for the number of intact steel wire ropes, it means that the number of intact steel wire ropes of the conveyor belt is insufficient to support the load, and the system will issue a warning and require maintenance or replacement.
[0006] In some embodiments, when the number of intact steel wire ropes is less than the threshold number of intact steel wire ropes, the number of cracks on a single cracked steel wire rope is further evaluated to determine the degree of its cracks, and based on the degree of the cracks, it is determined whether the cracked steel wire rope with a low degree of cracks can be regarded as equivalent to a intact steel wire rope.
[0007] In some embodiments, after obtaining the number of cracked steel ropes, the number of cracks in each of these cracked steel ropes is detected. At the same time, a crack number threshold is set, and the number of cracks in each of all cracked steel ropes is compared with the crack number threshold, and different responses are obtained based on the comparison results.
[0008] In some embodiments, if the number of cracks is less than or equal to the crack number threshold, it indicates that the number of cracks on the steel wire rope is small, the degree of cracks is low, and the possibility of breakage is small. Under this condition, the steel wire rope is marked as a usable steel wire rope; if the number of cracks is greater than the crack number threshold, it indicates that the number of cracks on the steel wire rope is large, the degree of cracks is high, and the possibility of breakage is high. Under this condition, the steel wire rope is marked as an unusable steel wire rope.
[0009] In some embodiments, two usable steel wire ropes are regarded as equivalent to one intact steel wire rope, the number of the equivalent intact steel wire ropes is recorded, the number of the equivalent intact steel wire ropes is added to the original number of intact steel wire ropes to obtain the total number of intact steel wire ropes, the total number of intact steel wire ropes is compared with the threshold number of intact steel wire ropes, and whether maintenance or replacement is required is determined based on the comparison result.
[0010] In some embodiments, if the number of available steel wire ropes is an odd number, all equivalent steel wire ropes are considered to be intact, one of which consists of three available steel wire ropes.
[0011] In some embodiments, when the number of intact steel wire ropes is greater than or equal to a threshold number of intact steel wire ropes, a threshold number of intact steel wire ropes that is greater than the threshold number of intact steel wire ropes but close to the threshold number of intact steel wire ropes is set, the number of intact steel wire ropes is compared with the threshold number of intact steel wire ropes, and different responses are obtained based on the comparison results.
[0012] In some embodiments, if the number of intact steel wire ropes is greater than the number of intact steel wire ropes approaching the threshold, the system continues to execute according to the original monitoring strategy; if the number of intact steel wire ropes is greater than or equal to the number of intact steel wire ropes threshold, but less than or equal to the number of intact steel wire ropes approaching the threshold, the system's monitoring strategy is changed to gradually shorten the monitoring period according to the degree of approaching the number of intact steel wire ropes threshold.
[0013] The present invention also provides the following technical solutions:
[0014] The present invention further provides an AI nondestructive flaw detection method for an eddy current steel wire rope core conveyor belt, the method comprising the following contents: first, obtaining the number of steel wire ropes in the conveyor belt and the number of steel wire ropes with cracks in the steel wire ropes, and subtracting the number of steel wire ropes with cracks from the number of steel wire ropes to obtain the number of intact steel wire ropes; second, setting a threshold value for the number of intact steel wire ropes; finally, comparing the number of intact steel wire ropes with the threshold value for the number of intact steel wire ropes; if the number of intact steel wire ropes of the conveyor belt is greater than or equal to the set threshold value for the number of intact steel wire ropes, it means that the conveyor belt can withstand sufficient load and has the ability to operate normally, and the system will allow continued use and perform status monitoring when necessary; if the number of intact steel wire ropes is lower than the set threshold value for the number of intact steel wire ropes, it means that the number of intact steel wire ropes of the conveyor belt is insufficient to support the load, and the system will issue a warning and require maintenance or replacement.
[0015] The present invention further provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement the above-mentioned eddy current steel wire core conveyor belt AI non-destructive flaw detection system.
[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:
[0017] First, in the present invention, the number of intact steel wire ropes in the conveyor belt is compared with the threshold value of the number of intact steel wire ropes. If it is greater than or equal to the threshold value of the number of intact steel wire ropes, it indicates that the conveyor belt can bear enough load. If it is less than the threshold value of the number of intact steel wire ropes, it indicates that it is insufficient to bear the load. In this way, the load capacity of the conveyor belt can be reflected by the number of intact steel wire ropes. Compared with the evaluation of crack depth and size, which requires a large amount of data and calculation support, the quantitative reflection is more intuitive and easy to operate.
[0018] Secondly, in the present invention, when the number of intact steel wire ropes is less than the threshold value of the number of intact steel wire ropes, the number of cracks on the cracked steel wire rope is further evaluated, and the degree of cracks is defined according to the number of cracks. For cracked steel wire ropes with low crack degrees, two or more wire ropes can be regarded as one intact steel wire rope, and then the number of intact steel wire ropes regarded as equivalent and the original number of intact steel wire ropes are added to obtain the total number of intact steel wire ropes, and this total number is compared with the threshold value of the number of intact steel wire ropes to determine whether maintenance and replacement are required. In this way, the problem of excessive maintenance caused by judging only based on the number of intact steel wire ropes is avoided, and it is not overly complicated, and the complexity and intuitiveness of steel wire rope flaw detection are balanced.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] It is to 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 an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0023] The present invention provides an eddy current steel cord conveyor belt AI nondestructive flaw detection system, such as Figure 1 and Figure 2 As shown, including:
[0024] Wire rope parameter acquisition module: In this module, first, the number of wire ropes in the conveyor belt is obtained through the parameter information and instruction manual information of the conveyor belt, and the number of wire ropes is recorded as the first parameter. The reason why there is a number of wire ropes is that the eddy current wire rope is formed into a whole by weaving, twisting, etc. of multiple wires. Each wire is usually spiral-shaped, and they do not directly contact each other during the twisting process, but have a certain gap and space. In other words, in the eddy current wire rope, there is no direct contact between the steel wires, but the structure formed by twisting and weaving allows them to maintain relative independence. Each steel wire bears a different load, which can effectively share the tension and reduce the fatigue and wear of a single steel wire. Secondly, the steel wire ropes in the conveyor belt are detected by ultrasonic sensors, and non-destructive flaw detection is performed to obtain the number of steel wire ropes with cracks in these steel wire ropes. The number of steel wire ropes minus the number of steel wire ropes with cracks is the number of intact steel wire ropes, and the number of intact steel wire ropes is recorded as a basis for subsequent judgment.
[0025] Wire rope threshold setting module: In this module, a threshold value for the number of intact wire ropes is set as a benchmark for evaluating whether the conveyor belt can operate normally. The setting of the threshold value for the number of intact wire ropes is not only based on the total number of wire ropes in the conveyor belt, but also takes into account the quality, structural strength, and aging and wear of the wire ropes during actual use. In addition, when setting the threshold value for the number of intact wire ropes, it is necessary to comprehensively consider factors such as the load capacity of the conveyor belt, the working conditions of the wire ropes, and the service life of the conveyor belt. In a conveyor belt, a cracked wire rope means that the wire rope has defects. Although the defects represented by wire ropes with different numbers, depths, and sizes of cracks vary in size, it is too complicated to evaluate the degree of defects of a defective wire rope based on the number, depth, and size of cracks. For a conveyor belt, the most critical thing is to be able to carry the load and operate normally. Therefore, it is more intuitive to directly evaluate whether it can carry the load and operate normally based on the number of remaining intact wire ropes. In general, due to the diversity of crack morphology, uneven distribution, dynamic changes in load conditions, and the complexity of multi-layer braided structures, it becomes very complicated to evaluate the degree of defects of a defective wire rope by the number, depth, size, etc. of cracks. Simply relying on these factors to evaluate the load-bearing capacity of wire ropes not only requires a large amount of data and calculation support, but also easily leads to inaccurate evaluation of the overall load-bearing capacity due to the local nature of the cracks. Therefore, directly using the number of intact wire ropes as the evaluation standard simplifies the judgment process, avoids excessive complication of crack details, and is more intuitive and easy to operate, meeting the needs of actual engineering applications.
[0026] Wire rope parameter comparison and response module: In this module, the number of intact wire ropes is compared with the threshold of the number of intact wire ropes, and different response methods are obtained according to the comparison results. If the number of intact wire ropes of the conveyor belt is greater than or equal to the set threshold of the number of intact wire ropes, it means that the conveyor belt can withstand sufficient load and has the ability to operate normally. The system will allow continued use and perform status monitoring when necessary. However, if the number of intact wire ropes is lower than the set threshold of the number of intact wire ropes, it means that the number of intact wire ropes of the conveyor belt is insufficient to support the load, and there may be a risk of overload or damage. The system will issue a warning and require maintenance or replacement to prevent safety accidents. This approach can effectively improve the safety and reliability of the conveyor belt, ensure the stable operation of the equipment under high-load working conditions, and provide a scientific basis for subsequent repairs and maintenance.
[0027] Through the joint work of the above modules, the AI non-destructive flaw detection system for eddy current steel wire core conveyor belts not only ensures the operational stability of the conveyor belt, but also greatly improves the safety and reliability of the system by setting the threshold for the number of intact steel wire ropes and real-time monitoring. In this way, the system can accurately identify whether the conveyor belt has sufficient carrying capacity, and promptly warn when potential damage or defects occur, providing a scientific basis for subsequent repairs and maintenance. The system effectively reduces human intervention and improves the level of automation, while reducing the failure rate of the conveyor belt, extending the service life of the equipment, and ensuring continuous and stable operation under high-load working conditions.
[0028] On the basis of the above, the steel wire ropes without cracks are identified as intact steel wire ropes. When the number of intact steel wire ropes is less than the threshold number of intact steel wire ropes, it is determined that the steel wire ropes in the conveyor belt are insufficient to bear the load and cannot work normally. Although such a judgment is more intuitive and avoids excessive complication of crack details, it is also easy to cause problems of excessive maintenance and replacement. Therefore, when the number of intact steel wire ropes is less than the threshold number of intact steel wire ropes, further crack evaluation is carried out, and only the number of cracks on a single cracked steel wire rope is evaluated to determine the degree of cracks of the cracked steel wire rope, and two or more cracked steel wire ropes with low crack degrees are regarded as one intact steel wire rope, and then the number of intact steel wire ropes regarded as equivalent is added to the original number of intact steel wire ropes to obtain the total number of intact steel wire ropes, and then the total number of intact steel wire ropes is compared with the threshold number of intact steel wire ropes. In this way, there is no excessive study of crack details leading to complexity, and the problem of excessive maintenance caused by only evaluating the number of intact steel wire ropes is avoided. Because the number of cracks directly reflects the overall degree of damage to the wire rope. An increase in the number of cracks means fatigue, uneven force and a decrease in the structural strength of the wire rope, which in turn leads to a weakening of its bearing capacity and an increased risk of fracture. Moreover, as an intuitive and easily quantifiable indicator, the number of cracks can simplify the assessment of the health status of the wire rope without in-depth analysis of the specific morphology, depth and expansion trend of each crack. Although these specific crack parameters (such as depth, width, etc.) are also important, their calculation is more complicated and requires more sensor support. Assessing the degree of cracks by the number of cracks not only simplifies the analysis process, but also provides an effective early warning during the overall assessment. The specific method is as follows: when the number of intact wire ropes is less than the threshold of the number of intact wire ropes, the number of cracked wire ropes is obtained, and the number of cracks in each of these cracked wire ropes is further detected by ultrasonic sensors, and the number of cracks is recorded as a basis for subsequent judgment. At the same time, the threshold of the number of cracks on the wire rope is set according to the design information and parameter information of the wire rope. This crack number threshold means that when the number of cracks on a single wire rope does not exceed that, although the wire rope has cracks, its crack degree is low and the possibility of breaking is low, so it can continue to be used. Under this condition, the number of cracks in each of all cracked wire ropes is compared with the crack number threshold, and different responses are obtained based on the comparison results. If the crack number is less than or equal to the crack number threshold, it means that the number of cracks on the wire rope is small, the crack degree is low, and the possibility of breaking is low. Under this condition, the wire rope is marked as a usable wire rope. If the crack number is greater than the crack number threshold, it means that the number of cracks on the wire rope is large, the crack degree is high, and the possibility of breaking is high. Under this condition, the wire rope is marked as an unusable wire rope.After the above processing, the number of all available steel wire ropes is recorded. Since these steel wire ropes are in a state of being available but with a low degree of cracks, when equating them to intact steel wire ropes, one available steel wire rope cannot be equated to one intact steel wire rope. Two or more available steel wire ropes are required to be equated to one intact steel wire rope. Here, two available steel wire ropes are selected to be equivalent to one intact steel wire rope. All available steel wire ropes are processed according to this method, and the number of equivalent intact steel wire ropes is recorded. In this process, it is worth mentioning that since the present invention treats two available steel wire ropes as equivalent to one intact steel wire rope, if the number of available steel wire ropes is an even number, the number of equivalent intact steel wire ropes recorded at the end is half of the number of available steel wire ropes. If the number of available wire ropes is an odd number, there will be one available wire rope left. In this case, the remaining available wire rope will be merged into one of the equivalent intact wire ropes, that is, among all the equivalent intact wire ropes, one of them is composed of three available wire ropes. Finally, based on the above, the number of equivalent intact wire ropes and the original intact wire ropes are added to obtain the total number of intact wire ropes. The total number of intact wire ropes is then compared with the intact wire rope number threshold, and the comparison result is used to determine whether maintenance or replacement is required. If the total number of intact wire ropes is greater than or equal to the set intact wire rope number threshold, it means that the conveyor belt can withstand sufficient load and has the ability to operate normally. The system will allow it to continue to be used and perform status monitoring when necessary. If the total number of intact wire ropes is lower than the set intact wire rope number threshold, it means that the number of intact wire ropes of the conveyor belt is insufficient to support the load and maintenance or replacement is required. The above method avoids the problem of making maintenance decisions based solely on the number of intact wire ropes by introducing further judgments on the number and degree of cracks in cracked wire ropes. This can effectively reduce maintenance and replacement caused by overly conservative judgments and reduce maintenance costs. In addition, by treating wire ropes with low crack levels as intact wire ropes, it further ensures that when the number of intact wire ropes is less than the threshold, the availability of the wire ropes can still be reasonably judged to avoid excessive replacement of wire ropes. In other words, while reducing excessive maintenance and replacement, this method also improves the accuracy and flexibility of conveyor belt health detection through further crack evaluation and reasonable wire rope number conversion strategies. Through intelligent evaluation of the number and degree of cracks, unnecessary maintenance expenses can be avoided while ensuring the safe operation of the equipment, and a solution that balances complexity and intuitiveness is provided.
[0029] When the number of intact wire ropes is greater than or equal to the threshold of the number of intact wire ropes, it indicates that the wire ropes in the current conveyor belt can bear the load and the conveyor belt can work normally. However, if the number of intact wire ropes is close to the threshold of the number of intact wire ropes, for example, the threshold of the number of intact wire ropes is 10, and the number of intact wire ropes is 11 or 12. At this time, although the number of intact wire ropes is still greater than or equal to the threshold of the number of intact wire ropes, it is very close, so there will be more concerns about whether the number of intact wire ropes will drop to the threshold of the number of intact wire ropes or below the threshold. In other words, as the number of intact wire ropes gets closer and closer to the threshold of the number of intact wire ropes, the probability that the conveyor belt can work normally will become lower and lower, and the possibility that the number of intact wire ropes is less than the threshold of the number of intact wire ropes will become higher and higher. In this case, in order to ensure that when the number of intact wire ropes drops to the threshold of the number of intact wire ropes or below, it can be discovered in time, the monitoring method of the response system should be changed. The details are as follows: set a threshold value for the number of intact wire ropes that is greater than the threshold value for the number of intact wire ropes but close to the threshold value for the number of intact wire ropes, compare the number of intact wire ropes with the threshold value for the number of intact wire ropes, and come up with different responses based on the comparison results. If the number of intact wire ropes is greater than the threshold value for the number of intact wire ropes, it means that the number of intact wire ropes is far greater than the threshold value for the number of intact wire ropes, and the number of intact wire ropes is still far from reaching the threshold value for the number of intact wire ropes. In this case, the system can continue to execute according to the original monitoring strategy. If the number of intact wire ropes is greater than or equal to the threshold value for the number of intact wire ropes, but less than or equal to the threshold value for the number of intact wire ropes, it means that the number of intact wire ropes is close to the threshold value for the number of intact wire ropes, and the number of intact wire ropes is close to reaching the threshold value for the number of intact wire ropes. In this case, dynamically adjust the monitoring strategy of the system. The dynamic adjustment method is as follows: when the number of intact steel wire ropes is less than the threshold value of the number of intact steel wire ropes, the area between the threshold value of the number of intact steel wire ropes and the threshold value of the number of intact steel wire ropes is divided into several areas, and each area is arranged from large to small according to the number of intact steel wire ropes, namely the first area, the second area, ..., the Nth area. Starting from the first area, the monitoring period of the system is shortened in proportion in sequence, and the area into which the number of intact steel wire ropes falls is determined, and the monitoring period of the system is dynamically adjusted to the period of the corresponding area. For example, assuming that the threshold value of the number of intact steel wire ropes is 10 and the threshold value of the number of intact steel wire ropes is 14, the area between the two is divided into the first area (14 intact steel wire ropes), the second area (13 intact steel wire ropes), the third area (12 intact steel wire ropes), the fourth area (11 intact steel wire ropes), and the fifth area (10 intact steel wire ropes).Assuming that the original monitoring cycle is once every N hours, the monitoring cycle of the first area is shortened to once every 5N / 10 hours, the monitoring cycle of the second area is shortened to once every 4N / 10 hours, the monitoring cycle of the third area is shortened to once every 3N / 10 hours, the monitoring cycle of the fourth area is shortened to once every 2N / 10 hours, and the monitoring cycle of the fifth area is shortened to once every N / 10 hours. Assuming that the number of intact wire ropes is 12, it falls into the third area, and the monitoring cycle of the system is shortened from once every N hours to once every 3N / 10 hours. In general, in order to ensure that potential problems can be discovered in time when the number of intact wire ropes approaches the critical value (the threshold value of the number of intact wire ropes), a strategy for dynamically adjusting the monitoring cycle is proposed. When the number of intact wire ropes is greater than or equal to the threshold value of the number of intact wire ropes, it indicates that the conveyor belt can work normally. However, if the number of intact wire ropes is close to the threshold value of the number of intact wire ropes, monitoring needs to be strengthened to cope with possible changes. To this end, a threshold value for the number of intact wire ropes is set and compared with the actual number. Different strategies are adopted according to the comparison results: if the number of intact wire ropes is greater than the threshold value for the number of intact wire ropes, the original monitoring strategy is continued; if it is less than or equal to the threshold value for the number of intact wire ropes, the monitoring cycle is dynamically adjusted, the gap between the two is divided into several areas, and the monitoring cycle is gradually shortened according to the number of intact wire ropes in each area. This method can ensure that when the number of intact wire ropes is close to the threshold value for the number of intact wire ropes, problems are discovered in time and corresponding measures are taken to avoid unexpected equipment failures.

6. The AI nondestructive flaw detection system for eddy current steel cord conveyor belt according to claim 5 is characterized in that: If the number of usable wire ropes is an odd number, all equivalent wire ropes are considered to be intact, one of which consists of three usable wire ropes.
7. The AI nondestructive flaw detection system for eddy current steel cord conveyor belt according to claim 1 is characterized in that: When the number of intact steel wire ropes is greater than or equal to the threshold number of intact steel wire ropes, a threshold number of intact steel wire ropes approaching the threshold number of intact steel wire ropes is set, which is greater than the threshold number of intact steel wire ropes but close to the threshold number of intact steel wire ropes, and the number of intact steel wire ropes is compared with the threshold number of intact steel wire ropes approaching the threshold number of intact steel wire ropes, and different responses are obtained according to the comparison result.
8. The AI nondestructive flaw detection system for eddy current steel cord conveyor belt according to claim 7 is characterized in that: If the number of intact wire ropes is greater than the number of intact wire ropes and is close to the threshold, the system continues to execute according to the original monitoring strategy; If the number of intact wire ropes is greater than or equal to the intact wire rope number threshold, but less than or equal to the intact wire rope number approaching threshold, the system's monitoring strategy is changed to gradually shorten the monitoring period according to the degree of approaching the intact wire rope number threshold.
9. The AI nondestructive flaw detection method for eddy current steel cord conveyor belt according to any one of claims 1 to 8, characterized in that: The method includes the following: First, the number of steel wire ropes in the conveyor belt and the number of steel wire ropes with cracks are obtained, and the number of intact steel wire ropes is obtained by subtracting the number of cracked steel wire ropes from the number of steel wire ropes; secondly, a threshold value for the number of intact steel wire ropes is set; Finally, the number of intact wire ropes is compared with the threshold value of the number of intact wire ropes. If the number of intact wire ropes of the conveyor belt is greater than or equal to the set threshold value of the number of intact wire ropes, it means that the conveyor belt can withstand sufficient load and has the ability to operate normally. The system will allow it to continue to be used and perform status monitoring when necessary. If the number of intact wire ropes is lower than the set threshold value of the number of intact wire ropes, it means that the number of intact wire ropes of the conveyor belt is insufficient to support the load. The system will issue a warning and require maintenance or replacement.
