Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of belt state detection, and in particular to a belt state detection method based on AI detection and recognition. Background Art
[0002] In industries such as coal, mining, and electricity, conveyor belts are important material transportation equipment, and their operating status is directly related to production efficiency and safety. However, traditional belt status detection methods mostly rely on manual inspections and simple sensor monitoring, which have problems such as untimely monitoring, poor accuracy, and slow response speed. With the rapid development of artificial intelligence technology, AI-based belt status detection systems have gradually become a research hotspot and have broad application prospects.
[0003] The existing methods for monitoring energy consumption in engineering construction still have the following problems: 1. When detecting the belt deviation status, the current method is based only on manual observation to determine whether the belt is deviated, which results in a large error in confirming the deviation status. At the same time, when the belt deviates, manual investigation of the cause of the deviation is not only time-consuming, but also cumbersome, and the cause of the belt deviation cannot be accurately located, reducing the efficiency of investigating the cause of the belt deviation.
[0004] 2. When detecting the wear status of the belt, the wear degree of the belt is currently judged only by observing the overall pattern of the belt to see whether it is broken or flattened. The wear condition of each pattern in the belt in the vertical direction is not analyzed, which reduces the coverage of the belt wear analysis and the accuracy of the belt wear degree judgment, and cannot guarantee the good condition of the belt.
[0005] 3. When detecting the tearing status of the belt, the cracking posture of each crack in each area of the belt is not deeply analyzed. Only the density of cracks in each area is considered without considering the cracking angle of each crack. The analysis dimension is relatively single, and it is impossible to accurately evaluate the expansion direction and speed of the cracks, thereby failing to provide effective data support for the prevention and control of tearing. At the same time, potential tearing risks may not be discovered in time, thereby increasing the possibility of belt tearing accidents. Summary of the invention
[0006] In view of this, in order to solve the problems raised in the above background technology, a belt status detection method based on AI detection and recognition is proposed.

If it is deviated, execute step S2, and if it is not deviated, execute step S3.
[0008] S2. Confirmation and feedback of the cause of deviation: Collect the tension of each monitoring point of the target belt during each operation, the rotation speed of the two rollers and the vibration frequency of the motor, confirm the cause of the deviation of the target belt, and provide feedback.
[0009] S3. Belt wear detection: randomly arrange detection points in each component pattern of each area of the target belt, construct a three-dimensional information model of each area, and obtain the y-axis coordinate value of each detection point in each component pattern of each area to analyze the wear degree of each area of the target belt.
[0010] S4. Confirmation and feedback of wear degree: confirm the wear degree of each area of the target belt and provide feedback of the wear degree of each area.
[0011] S5. Belt tear detection warning: collect images corresponding to each area of the target belt, analyze the tear severity coefficient of the target belt, and compare it with the set value. If it is greater than or equal to the set value, a tear severity warning is issued.
[0012] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention determines whether the target belt is deviating based on the running video of the target belt. If it is deviating, the cause of the deviation of the target belt is confirmed according to the tension of each monitoring point of the target belt during each operation, the rotation speed of the two rollers and the vibration frequency of the motor, thereby reducing the error existing in manual observation of whether the belt state is deviating, and avoiding the problems of long time-consuming cycle and cumbersome troubleshooting process in manual troubleshooting of the cause of the deviation, thereby improving the efficiency of troubleshooting the cause of the belt deviation.
[0013] (2) The present invention constructs a three-dimensional information model of each area, and obtains the y-axis coordinate value of each detection point in each component pattern of each area, analyzes the wear degree of each area of the target belt, improves the coverage of the belt wear analysis, and at the same time improves the accuracy of the belt wear degree judgment, thereby ensuring the good condition of the belt.
[0014] (3) The present invention calculates the crack density and crack opening angle hazard coefficient of the target belt based on the images corresponding to each area of the target belt, thereby analyzing the tear severity coefficient of the target belt.

If it is deviated, execute step S2, if it is not deviated, execute step S3.
[0019] In a specific embodiment of the present invention, the target belt has two edges. This embodiment takes any one of the edges as an example for analysis. The analysis of the two edges is similar to the analysis of one edge, which will not be repeated here.

[0026] In a specific embodiment of the present invention, a 1 The setting value is 0.5, a 2 The setting value is 0.5. The average deviation distance deviation can reflect the average deviation degree of the belt during the overall operation process, helping to understand the overall trend of belt deviation. The maximum deviation distance deviation can reveal the degree of belt deviation under extreme conditions, which is of great significance for evaluating the safety risks that may be caused by deviation. It is usually necessary to comprehensively consider the average deviation distance deviation and the maximum deviation distance deviation. The two can complement each other and provide more comprehensive belt deviation information.
[0027] A4. Compare the deviation of the target belt with the deviation of the set reference. If the deviation of the target belt is greater than or equal to the deviation of the set reference, it indicates that the target belt is deviated. Otherwise, it indicates that the target belt is not deviated.
[0028] S2. Confirmation and feedback of the cause of deviation: Collect the tension of each monitoring point of the target belt during each operation, the rotation speed of the two rollers and the vibration frequency of the motor, confirm the cause of the deviation of the target belt, and provide feedback.

[0036] C3. Based on the vibration frequency of the motor of the target belt during each operation, the vibration abnormality index ξ of the target belt during the operation is calculated.
[0037] It should be noted that the specific process of calculating the vibration abnormality index of the target belt during operation is as follows: the vibration frequency of the motor of the target belt during each operation is recorded as μ d .
[0038] Calculate the vibration abnormality index ξ of the target belt during operation, Here, μ′ and Δμ represent the vibration frequency and vibration frequency deviation of the set reference, respectively.
[0039] C4. When δ<δ′, the cause of the deviation of the target belt is recorded as uneven tension; when ω<ω′, the cause of the deviation of the target belt is recorded as asynchronous roller rotation; when ξ≥ξ′, the cause of the deviation of the target belt is recorded as abnormal motor vibration, wherein δ′, ω′ and ξ′ represent the tension uniformity, roller rotation synchronization and vibration abnormality index of the set reference, respectively.
[0040] The embodiment of the present invention determines whether the target belt is deviating based on the running video of the target belt. If deviating, the cause of the deviation of the target belt is confirmed according to the tension of each monitoring point of the target belt during each operation, the rotation speed of the two rollers and the vibration frequency of the motor, thereby reducing the error existing in manual observation of whether the belt state is deviating, and at the same time avoiding the problems of long time-consuming cycle and cumbersome troubleshooting process in manual troubleshooting of the cause of the deviation, thereby improving the efficiency of troubleshooting the cause of the belt deviation.

[0050] In a specific embodiment of the present invention, the method for confirming the degree of wear of each area of the target belt is: comparing the degree of wear of each area of the target belt with the wear degree set corresponding to each degree of wear stored in the database; if the degree of wear of a certain area is within the wear degree set corresponding to a certain degree of wear, then the degree of wear is used as the degree of wear of the area, thereby obtaining the degree of wear of each area of the target belt.
[0051] The embodiment of the present invention constructs a three-dimensional information model of each area, and obtains the y-axis coordinate value of each detection point in each component texture of each area, analyzes the wear of each area of the target belt, thereby improving the coverage of the belt wear analysis, and at the same time improves the accuracy of judging the degree of belt wear, thereby ensuring the good condition of the belt.
[0052] S5. Belt tear detection warning: collect images corresponding to each area of the target belt, analyze the tear severity coefficient of the target belt, and compare it with the set value. If it is greater than or equal to the set value, a tear severity warning is issued.
[0053] It should be noted that the images corresponding to each area of the target belt are acquired by a high-definition camera.
[0054] In a specific embodiment of the present invention, the specific process of analyzing the tear severity coefficient of the target belt is as follows: G1, locating the number of cracks, the length of each crack, the length of the region and the area of the region from the image corresponding to each region of the target belt, and calculating the crack density of the target belt
[0055] It should be noted that the specific process of calculating the crack density of the target belt is as follows: the number of cracks, the length of the region and the area of the region corresponding to each region of the target belt are respectively recorded as M r , l r and S r .
[0056] The maximum value of each crack length corresponding to each area of the target belt is extracted and recorded as

[0058] G2. Calculate the crack angle hazard coefficient ψ of the target belt.
[0059] In a specific embodiment of the present invention, the specific process of calculating the crack opening angle hazard coefficient of the target belt is: H1. Establish a rectangular coordinate system with the center point of one side edge of the target belt as the origin, the direction of the belt conveying the goods as the y-axis, and the direction perpendicular to the belt conveying the goods as the x-axis.
[0060] H2. Locate the coordinates of the two endpoints of each crack corresponding to each region in the rectangular coordinate system and record them as and Wherein, w represents the crack number, w=1,2,...,u.
[0061] H3. Calculate the angle θ of each crack in each area rw ,
[0062] H4, the angle of each crack in each area is 0 The difference between each crack in each area and 0 0 The deviation angle between them is recorded as the first deviation angle. If the first deviation angle of a crack in a certain area is less than the set first deviation angle, the crack is determined to be a first deviation crack. The number of first deviation cracks in each area is counted and recorded as
[0063] H5. Compare the angles of each crack in each region with 90 0 The difference between each crack in each area and 90 0 The deviation angle between the cracks in each area and the 0The absolute value of the deviation angle between is recorded as the second deviation angle.

[0065] It should be noted that the crack angles of the target belt in the direction of the goods conveyed by the belt and perpendicular to the direction of the goods conveyed by the belt are more likely to lead to rapid crack expansion and cause more serious structural damage to the target belt. Therefore, when calculating the crack angle hazard factor of the target belt, the crack angles in the direction of the goods conveyed by the belt and perpendicular to the direction of the goods conveyed by the belt are mainly considered.
[0066] G3. Calculate the tear severity coefficient θ of the target belt. Among them, b 1 and b 2 They represent the weights of the tear severity assessment corresponding to the crack density and crack angle hazard factor of the reference, b 1 +b 2 =1.
[0067] In a specific embodiment of the present invention, b 1 The setting value of is 0.5, b 2 The setting value is 0.5. The crack density reflects the number and distribution of cracks on the belt surface. A high density of cracks means that the structural integrity of the belt is more seriously damaged, which may cause the belt to lose its load-bearing capacity more quickly or break suddenly. Therefore, the crack density is an important indicator for measuring the risk of belt tearing. The crack opening angle can affect the crack propagation speed and direction, and thus affect the overall strength and stability of the belt. Therefore, when calculating the tear severity coefficient of the target belt, the crack density and crack opening angle hazard coefficient should be comprehensively considered.
[0068] The embodiment of the present invention calculates the crack density and crack opening angle hazard coefficient of the target belt according to the images corresponding to each area of the target belt, thereby analyzing the tear severity coefficient of the target belt, and can accurately evaluate the expansion direction and speed of the crack, thereby providing effective data support for preventing and controlling tearing, and helping to timely discover potential tearing risks, thereby reducing the possibility of belt tearing accidents.
