Description

Technical Field

Background Art

[0002] As an important industrial material, steel wire rope is widely used in various fields such as mines, ports, bridges, buildings, elevators, etc. However, as the use time of steel wire rope increases, its internal parts may be damaged by corrosion, wire breakage, wear and tear, etc. If these damages are not discovered and handled in time, they will seriously affect the safety of steel wire rope use and even lead to major accidents. Therefore, it is particularly important to conduct regular and accurate non-destructive testing of steel wire ropes.

[0003] At present, there are a variety of non-destructive testing technologies and methods for wire ropes on the market, but most of them have problems such as low detection accuracy, complex operation, and low detection efficiency. Therefore, the development of an efficient, accurate, and easy-to-operate non-destructive testing equipment for wire ropes is of great significance for improving the safety of wire rope use and reducing the risk of accidents. Some non-destructive testing technologies, such as magnetic particle testing and penetration testing, require the wire rope to be inspected section by section, which makes the detection speed slow and difficult to adapt to the needs of large-scale or continuous operations. Although ultrasonic testing can detect defects inside the wire rope, its detection depth is limited by the penetration ability of ultrasound, and it may not be able to effectively detect internal defects for thicker or thicker wire ropes. In harsh industrial environments, such as high temperature, high humidity, and dust, the performance of some non-destructive testing equipment may be affected, resulting in inaccurate test results.

[0025] As introduced in the background technology, although ultrasonic testing in the prior art can detect defects inside the wire rope, its detection depth is limited by the penetration ability of ultrasonic waves. For thicker or thicker wire ropes, internal defects may not be effectively detected. In order to solve the problem that the prior art cannot effectively detect internal defects of thicker or thicker wire ropes, the embodiments of the present application provide a wire rope nondestructive testing equipment, a wire rope nondestructive testing method, a wire rope nondestructive testing device, a computer readable storage medium and a computer program product.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Figure 1 A schematic diagram of the structure of a nondestructive testing device for steel wire ropes provided in an embodiment of the present application is shown. Figure 1 As shown, the wire rope nondestructive testing equipment includes:

[0028] An electromagnetic induction probe, the electromagnetic induction probe comprising an excitation coil and a receiving coil, the excitation coil is used to generate an alternating magnetic field, the receiving coil is used to receive an induction signal generated by the alternating magnetic field and convert the induction signal into an electrical signal;

[0029] A moving mechanism, the moving mechanism is used to drive the electromagnetic induction probe to move along the axial direction of the steel wire rope to be detected, and the moving mechanism is connected to the electromagnetic induction probe;

[0030] A signal processing unit, the signal processing unit is used to receive the electrical signal and analyze and process the electrical signal to determine the damage degree and damage position of the steel wire rope to be detected;

[0031] The sensor is used to transmit the electrical signal to the signal processing unit, and the sensor is respectively communicatively connected with the signal processing unit, the moving mechanism and the electromagnetic induction probe.

[0032] In the above-mentioned nondestructive testing equipment for steel wire ropes, the above-mentioned electromagnetic induction probe 1 includes an excitation coil and a receiving coil, the above-mentioned excitation coil is used to generate an alternating magnetic field, and the above-mentioned receiving coil is used to receive the induction signal generated by the above-mentioned alternating magnetic field and convert the above-mentioned induction signal into an electrical signal; the above-mentioned moving mechanism 2 drives the above-mentioned electromagnetic induction probe 1 to move axially along the steel wire rope to be tested, and the above-mentioned moving mechanism 2 is connected to the above-mentioned electromagnetic induction probe 1; the above-mentioned signal processing unit 3 receives the above-mentioned electrical signal and analyzes and processes the above-mentioned electrical signal to further determine the damage degree and damage position of the above-mentioned steel wire rope to be tested; the above-mentioned sensor 4 is used to transmit the above-mentioned electrical signal to the above-mentioned signal processing unit 3, and the above-mentioned sensor 4 is respectively connected to the above-mentioned signal processing unit 3, the above-mentioned moving mechanism 2 and the above-mentioned electromagnetic induction probe 1 through the signal line 5.

[0033] In order to improve the strength and stability of the detection signal, the above-mentioned wire rope non-destructive testing equipment also includes:

[0034] The diameter adjustment mechanism is used to obtain the diameter of the steel wire rope to be detected, and adjust the parameters of the excitation coil and the receiving coil according to the diameter of the steel wire rope to be detected.

[0035] In the above embodiment, the main function of the diameter adjustment mechanism is to obtain the diameter of the steel wire rope to be detected, and adjust the parameters of the excitation coil and the receiving coil according to the measurement results to improve the detection precision and accuracy. Measuring the diameter of the steel wire rope: The diameter adjustment mechanism can accurately measure the diameter of the steel wire rope to be detected through a high-precision sensor or measuring device. This is crucial for subsequent detection work, because the diameter of the steel wire rope directly affects the parameter settings of the excitation coil and the receiving coil. According to the measured diameter of the steel wire rope, the diameter adjustment mechanism will automatically adjust the parameters of the excitation coil and the receiving coil, such as the current of the coil. This ensures that the electromagnetic coupling effect between the coil and the steel wire rope is optimal, thereby improving the strength and stability of the detection signal. By automatically adjusting the parameters of the excitation coil and the receiving coil, the diameter adjustment mechanism can ensure that the detection system can obtain stable detection signals on steel wire ropes of different diameters, thereby improving the precision and accuracy of the detection results.

[0036] In order to ensure that the sensor can accurately adapt to wire ropes of different diameters, the above-mentioned wire rope non-destructive testing equipment also includes:

[0037] A manual adjustment mechanism, the manual adjustment mechanism is used to manually adjust the gap between the sensor guide sleeve and the steel wire rope to be detected to adapt to steel wire ropes of different diameters, and the sensor guide sleeve is used to fix the sensor to the electromagnetic induction probe;

[0038] The automatic adjustment mechanism automatically controls the gap between the sensor guide sleeve and the steel wire rope to be detected through a predetermined control algorithm to adapt to steel wire ropes of different diameters.

[0039] In the above embodiment, the gap between the sensor guide sleeve and the wire rope is preferably 2 mm to 6 mm, and the allowable gap is 0 mm to 15 mm. Both the manual adjustment mechanism and the automatic adjustment mechanism are used to adjust the gap between the sensor guide sleeve and the wire rope to be detected to ensure that the sensor can accurately detect wire ropes of different diameters. The manual adjustment mechanism allows the operator to manually adjust the position of the sensor guide sleeve according to the actual detected wire rope diameter to ensure that the contact between the sensor and the wire rope is appropriate. In an environment without an automated system, the manual adjustment mechanism provides a simple and direct way to adapt to wire ropes of different diameters. Compared with the automatic adjustment mechanism, the manual adjustment mechanism is usually less expensive and suitable for occasions with limited budgets. In actual applications, the manual adjustment mechanism is usually used in the following situations: Preliminary setup: When installing or replacing the sensor, the operator will manually adjust the sensor guide sleeve to ensure that the gap between the sensor and the wire rope is appropriate. During regular maintenance, the operator may check and manually adjust the position of the sensor guide sleeve to ensure detection accuracy. When an abnormal situation is detected, the operator can quickly manually adjust the sensor guide sleeve to adapt to the changing wire rope diameter. The automatic adjustment mechanism automatically adjusts the position of the sensor guide sleeve through a predetermined control algorithm without manual intervention. The automatic adjustment mechanism can accurately adjust the position of the sensor guide sleeve according to real-time data to adapt to wire ropes of different diameters. The automatic adjustment mechanism can reduce manual operations and improve detection efficiency, especially in continuous production processes. The automatic adjustment mechanism reduces the possibility of human error and improves the reliability of the detection system. In practical applications, the automatic adjustment mechanism is usually used in the following situations: In a continuous production environment, the automatic adjustment mechanism can adjust the sensor guide sleeve in real time to adapt to the changing diameter of the wire rope. In the case of complex or frequently changing environmental conditions, the automatic adjustment mechanism can provide more stable detection results. In a remote monitoring system, the automatic adjustment mechanism can reduce the need for on-site operations and improve the degree of automation of the system. In general, both manual adjustment mechanisms and automatic adjustment mechanisms are designed to ensure that the sensor can accurately detect wire ropes of different diameters, but they differ in terms of operation methods, costs, application scenarios, etc. Which adjustment mechanism to choose depends on the specific application requirements, budget, and technical conditions.

[0040] In order to ensure that the detection device always maintains the best relative speed with the wire rope, thereby improving the accuracy of detection, the above-mentioned moving mechanism includes:

[0041] A speed control unit is used to automatically adjust the moving speed of the moving mechanism according to the signal strength during the non-destructive testing process so that the relative speed with the steel wire rope to be tested is maintained within a set range.

[0042] In the above embodiment, the relative speed between the sensor and the wire rope is: 0.0-6.0m / s, and the optimal relative speed is 0.3-1.5m / s. According to the change of signal strength, the speed control unit can automatically adjust the moving speed of the mobile mechanism to ensure the accuracy and efficiency of the detection process. By adjusting the moving speed, the speed control unit ensures that the relative speed between the mobile mechanism and the wire rope to be detected remains within the set range. By automatically adjusting the speed, it can be ensured that when the signal strength changes, the detection equipment always maintains the optimal relative speed with the wire rope, thereby improving the accuracy of the detection. Automated speed adjustment reduces human intervention, improves the efficiency of the detection process, and reduces the waste of detection time caused by improper speed. Automated control reduces errors caused by improper operation of operators and improves the reliability of detection. The speed control unit usually includes a feedback mechanism that can further fine-tune the speed according to the actual detection effect to adapt to different detection conditions. The speed control unit can also record historical data of speed adjustment for subsequent analysis to optimize the detection process and improve the detection quality.

[0043] In order to timely discover and deal with potential safety hazards of wire ropes, the above-mentioned signal processing unit includes:

[0044] A feature extraction module, the feature extraction module is used to analyze and process the electrical signal to extract damage feature information of the steel wire rope to be detected;

[0045] A feature judgment module, the feature judgment module is used to judge the damage degree and the damage position of the steel wire rope to be detected according to the damage feature information.

[0046] In the above embodiment, the feature extraction module is responsible for analyzing the electrical signals (which may be vibration, sound, resistance, etc.) collected from the wire rope, and can identify and extract feature information related to wire rope damage, such as cracks, wear, corrosion, etc. Before extracting the features, it may be necessary to perform preprocessing steps such as filtering and denoising on the signal to improve the accuracy of feature recognition. By accurately extracting the damage features, the damage state of the wire rope can be more accurately identified. Effective feature extraction can reduce the risk of false alarms and missing important damage. The feature judgment module judges the degree of damage of the wire rope based on the feature information provided by the feature extraction module, and can also determine the specific location of the damage. By accurately judging the degree and location of the damage, maintenance work can be arranged more effectively. Timely detection and treatment of damage can extend the service life of the wire rope and reduce replacement costs. The feature extraction module and the feature judgment module complement each other in the wire rope detection system, and jointly ensure the safe and effective use of the wire rope. Through accurate feature extraction and damage judgment, potential safety hazards can be discovered and handled in a timely manner, thereby improving the safety and efficiency of industrial production.

[0047] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 2 FIG. 1 is a hardware structure block diagram of a mobile terminal of a wire rope nondestructive testing method according to an embodiment of the present invention. Figure 2 As shown, the mobile terminal may include one or more ( Figure 2 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 2 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 2 More or fewer components as shown, or with Figure 2 Different configurations shown.

[0048] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the wire rope nondestructive testing method in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The above-mentioned specific examples of the network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0049] In this embodiment, a method for non-destructive testing of wire ropes running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0050] Figure 3 1 is a flow chart of a nondestructive testing method for a steel wire rope according to an embodiment of the present application. Figure 3 As shown, the method comprises the following steps:

[0051] Step S201, controlling the moving mechanism to drive the electromagnetic induction probe to move axially along the steel wire rope to be detected.

[0052] Specifically, the moving mechanism drives the electromagnetic induction probe to move along the axial direction of the steel wire rope to be tested, and a moving mechanism (which may be a slide rail or other automated equipment) is used to control the electromagnetic induction probe to move along the axial direction of the steel wire rope (i.e., along the length direction of the steel wire rope). The moving mechanism can be manually operated or automatically controlled to ensure that the electromagnetic induction probe can evenly and continuously cover the entire length of the steel wire rope. Ensure that the electromagnetic induction probe can detect every part of the steel wire rope in order to comprehensively evaluate the condition of the steel wire rope. By moving the probe, the entire length of the steel wire rope can be continuously tested, improving the coverage and accuracy of the test.

[0053] Step S202, controlling the excitation coil in the electromagnetic induction probe to generate an alternating magnetic field so that eddy currents are generated inside the steel wire rope to be detected, and at the same time controlling the receiving coil to receive the induction signal generated by the eddy currents inside the steel wire rope to be detected and converting the induction signal into the electrical signal, and transmitting the electrical signal to the sensor.

[0054] Specifically, the excitation coil in the electromagnetic induction probe is controlled to generate an alternating magnetic field. This alternating magnetic field generates eddy currents inside the steel wire rope to be detected. The receiving coil in the electromagnetic induction probe receives the induction signals generated by the eddy currents and converts these induction signals into electrical signals. The converted electrical signals are transmitted to the sensor. The alternating magnetic field interacts with the eddy currents inside the steel wire rope to detect defects and damage inside the steel wire rope.

[0055] Step S203, controlling the sensor to transmit the electrical signal to the signal processing unit, so that the signal processing unit receives the electrical signal and analyzes and processes the electrical signal, extracts the damage characteristic information of the steel wire rope to be detected, and determines the damage degree and damage position of the steel wire rope to be detected according to the damage characteristic information.

[0056] Specifically, the sensor, as a transmission medium, is connected to the mobile mechanism, the signal processing unit and the electromagnetic induction probe through a signal line, receives the electrical signal from the receiving coil, and transmits the electrical signal to the signal processing unit. The signal processing unit receives the electrical signal and analyzes and processes it. The signal processing unit can extract the damage characteristic information of the wire rope from the electrical signal, such as the type, size and location of the damage. By analyzing the signal, the degree and location of the damage of the wire rope can be judged more accurately, providing a basis for subsequent damage treatment.

[0057] Step S204: determining a damage treatment strategy according to the damage degree and the damage location to execute the damage treatment strategy.

[0058] Specifically, the degree and location of the wire rope damage are determined based on the damage feature information extracted by the signal processing unit. Based on the severity and location of the damage, a corresponding damage treatment strategy is formulated. The damage treatment strategy is implemented, which may include repair, replacement or further testing. Through accurate damage location and evaluation, the most appropriate measures can be taken to deal with the damage of the wire rope. This helps to extend the service life of the wire rope, improve safety, and reduce the risk of accidents caused by wire rope damage. The entire system is designed to improve the efficiency and accuracy of wire rope detection through automation and precise detection technology, thereby ensuring the safe use and maintenance of wire ropes.

[0059] In this embodiment, first, the moving mechanism is controlled to drive the electromagnetic induction probe to move axially along the steel wire rope to be detected; then, the excitation coil in the electromagnetic induction probe is controlled to generate an alternating magnetic field, so that eddy currents are generated inside the steel wire rope to be detected, and at the same time, the receiving coil is controlled to receive the induction signal generated by the eddy current inside the steel wire rope to be detected and convert the induction signal into the electrical signal, and transmit the electrical signal to the sensor; thereafter, the sensor is controlled to transmit the electrical signal to the signal processing unit, so that the signal processing unit receives the electrical signal and analyzes and processes the electrical signal, extracts the damage characteristic information of the steel wire rope to be detected, and judges the damage degree and the damage position of the steel wire rope to be detected based on the damage characteristic information; finally, a damage treatment strategy is determined based on the damage degree and the damage position to execute the damage treatment strategy. The present application provides a novel nondestructive testing method for steel wire ropes based on the principle of electromagnetic induction, including an electromagnetic induction probe, including an excitation coil and a receiving coil, the excitation coil is used to generate an alternating magnetic field, and the receiving coil is used to receive the signal induced by the alternating magnetic field; a moving mechanism is used to drive the electromagnetic induction probe to move along the axial direction of the steel wire rope; a signal processing unit is used to receive the electrical signal of the above-mentioned receiving coil, and analyze and process the signal, extract the damage characteristic information of the steel wire rope, and judge the degree and position of the damage of the steel wire rope according to the characteristic information. The information transmission between each structure is realized by a sensor. The electromagnetic induction principle is adopted to realize the rapid and nondestructive detection of steel wire rope damage. The present application solves the problem that the internal defects of the steel wire rope cannot be effectively detected for thicker or thicker steel wire ropes in the prior art.

[0060] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the steel wire rope non-destructive testing method of the present application will be described in detail below in combination with specific embodiments.

[0061] In order to efficiently detect the damage of the steel wire rope, in an optional implementation manner, the above step S203 includes:

[0062] Step S2031, generating a magnetic field distribution diagram of the steel wire rope to be detected according to the electrical signal;

[0063] Step S2032, when the magnetic field distribution diagram is not a continuous curve, extracting the notch degree and notch position in the magnetic field distribution diagram, wherein the notch degree and the notch position represent the damage characteristic information;

[0064] Step S2033, determining the damage degree and the damage position according to the notch degree and the notch position respectively;

[0065] Step S2034: when the magnetic field distribution diagram is the continuous curve, determine that the steel wire rope to be tested is not damaged.

[0066] In the above embodiment, electromagnetic sensors are arranged around the steel wire rope to be detected so as to detect the magnetic field around the steel wire rope. The electromagnetic sensor captures the magnetic field changes generated by the electrical signal, and the collected electrical signal data is processed by a computer to generate a magnetic field distribution map. Through the magnetic field distribution map, the magnetic field changes around the steel wire rope can be intuitively seen, and these changes may be related to the damage state of the steel wire rope. The magnetic field distribution map provides basic data for subsequent damage detection. The magnetic field distribution map is analyzed to identify discontinuous areas of magnetic field intensity, which indicate damage to the steel wire rope. The degree of decrease in magnetic field intensity in these discontinuous areas is measured, which can be used as a quantitative indicator of the degree of notch. The specific location of these discontinuous areas on the steel wire rope is determined, which can be used as a quantitative indicator of the position of the notch. The degree of notch and the position of the notch are key parts of the damage feature information, which can help determine the degree and position of the damage of the steel wire rope. By quantifying these features, the damage state of the steel wire rope can be more accurately evaluated. According to the degree of notch (degree of decrease in magnetic field intensity) and the position of the notch, combined with the pre-set damage assessment criteria, the degree of damage to the steel wire rope is determined.

Determining the degree and location of the damage helps to take appropriate maintenance measures, such as repairing or replacing the damaged part. Potential safety accidents can be prevented and the service life of the wire rope can be extended. If the magnetic field distribution diagram shows a continuous curve without obvious discontinuous areas, it means that the wire rope has no obvious damage. In this case, it can be considered that the wire rope is in good working condition. Confirming that the wire rope is not damaged can avoid unnecessary repairs and replacements, saving costs. Overall, detecting wire rope damage by analyzing the magnetic field distribution diagram is non-invasive, efficient and accurate, which is of great significance for ensuring the safe use of wire ropes and extending their service life.

[0072] Specifically, the moving mechanism drives the electromagnetic induction probe to move along the axial direction of the steel wire rope to be tested, and a moving mechanism (which may be a slide rail or other automated equipment) is used to control the electromagnetic induction probe to move along the axial direction of the steel wire rope (i.e., along the length direction of the steel wire rope). The moving mechanism can be manually operated or automatically controlled to ensure that the electromagnetic induction probe can evenly and continuously cover the entire length of the steel wire rope. Ensure that the electromagnetic induction probe can detect every part of the steel wire rope in order to comprehensively evaluate the condition of the steel wire rope. By moving the probe, the entire length of the steel wire rope can be continuously tested, improving the coverage and accuracy of the test.

[0074] Specifically, the excitation coil in the electromagnetic induction probe is controlled to generate an alternating magnetic field. This alternating magnetic field generates eddy currents inside the steel wire rope to be detected. The receiving coil in the electromagnetic induction probe receives the induction signals generated by the eddy currents and converts these induction signals into electrical signals. The converted electrical signals are transmitted to the sensor. The alternating magnetic field interacts with the eddy currents inside the steel wire rope to detect defects and damage inside the steel wire rope.

[0076] Specifically, the sensor, as a transmission medium, is connected to the mobile mechanism, the signal processing unit and the electromagnetic induction probe through a signal line, receives the electrical signal from the receiving coil, and transmits the electrical signal to the signal processing unit. The signal processing unit receives the electrical signal and analyzes and processes it. The signal processing unit can extract the damage characteristic information of the wire rope from the electrical signal, such as the type, size and location of the damage. By analyzing the signal, the degree and location of the damage of the wire rope can be judged more accurately, providing a basis for subsequent damage treatment.

[0077] The determination unit 40 is used to determine a damage treatment strategy according to the damage degree and the damage location, so as to execute the damage treatment strategy.

[0078] Specifically, the degree and location of the wire rope damage are determined based on the damage feature information extracted by the signal processing unit. According to the severity and location of the damage, a corresponding damage treatment strategy is formulated. The damage treatment strategy is implemented, which may include repair, replacement or further testing. Through accurate damage location and evaluation, the most appropriate measures can be taken to deal with the damage of the wire rope. This helps to extend the service life of the wire rope, improve safety, and reduce the risk of accidents caused by wire rope damage. The entire system is designed to ensure the safe use and maintenance of the wire rope through the efficiency and accuracy of automation and precise detection.

[0079] In this embodiment, the first control unit is used to control the above-mentioned moving mechanism to drive the above-mentioned electromagnetic induction probe to move axially along the above-mentioned wire rope to be detected; the second control unit is used to control the above-mentioned excitation coil in the above-mentioned electromagnetic induction probe to generate an alternating magnetic field, so that eddy currents are generated inside the above-mentioned wire rope to be detected, and at the same time control the above-mentioned receiving coil to receive the induction signal generated by the above-mentioned eddy current inside the above-mentioned wire rope to be detected and convert the above-mentioned induction signal into the above-mentioned electrical signal, and transmit the above-mentioned electrical signal to the above-mentioned sensor; the third control unit is used to control the above-mentioned sensor to transmit the above-mentioned electrical signal to the above-mentioned signal processing unit, so that the above-mentioned signal processing unit receives the above-mentioned electrical signal and analyzes and processes the above-mentioned electrical signal, extracts the damage characteristic information of the above-mentioned wire rope to be detected, and judges the above-mentioned damage degree and the above-mentioned damage position of the above-mentioned wire rope to be detected according to the above-mentioned damage characteristic information; the determination unit is used to determine the damage treatment strategy according to the above-mentioned damage degree and the above-mentioned damage position, so as to execute the above-mentioned damage treatment strategy.

The information transmission between each structure is realized by a sensor. The electromagnetic induction principle is adopted to realize the rapid and nondestructive detection of steel wire rope damage. The present application solves the problem that the internal defects of the steel wire rope cannot be effectively detected for thicker or thicker steel wire ropes in the prior art.

The electromagnetic sensor captures the magnetic field changes generated by the electrical signal, and the collected electrical signal data is processed by a computer to generate a magnetic field distribution map. Through the magnetic field distribution map, the magnetic field changes around the steel wire rope can be intuitively seen, and these changes may be related to the damage state of the steel wire rope. The magnetic field distribution map provides basic data for subsequent damage detection. The magnetic field distribution map is analyzed to identify discontinuous areas of magnetic field intensity, which indicate damage to the steel wire rope. The degree of decrease in magnetic field intensity in these discontinuous areas is measured, which can be used as a quantitative indicator of the degree of notch. The specific location of these discontinuous areas on the steel wire rope is determined, which can be used as a quantitative indicator of the position of the notch. The degree of notch and the position of the notch are key parts of the damage feature information, which can help determine the degree and position of the damage of the steel wire rope. By quantifying these features, the damage state of the steel wire rope can be more accurately evaluated. According to the degree of notch (degree of decrease in magnetic field intensity) and the position of the notch, combined with the pre-set damage assessment criteria, the degree of damage to the steel wire rope is determined. The degree of damage may be divided into mild, moderate and severe levels. The damage location indicates the specific damaged area on the wire rope. Determining the degree and location of the damage helps to take appropriate maintenance measures, such as repairing or replacing the damaged part. Potential safety accidents can be prevented and the service life of the wire rope can be extended. If the magnetic field distribution diagram shows a continuous curve without obvious discontinuous areas, it means that the wire rope has no obvious damage. In this case, it can be considered that the wire rope is in good working condition. Confirming that the wire rope is not damaged can avoid unnecessary repairs and replacements, saving costs. Overall, detecting wire rope damage by analyzing the magnetic field distribution diagram is non-invasive, efficient and accurate, which is of great significance for ensuring the safe use of wire ropes and extending their service life.
