Solder joint aging is one of the main causes of circuit failure and nuclear power plant equipment failure.

[0003] In the management and operation of nuclear power plants, the failure of nuclear power plant equipment will seriously affect the safe operation of nuclear power plants. Therefore, it is of great significance to detect the aging of solder joints in nuclear power plant equipment. Existing nuclear power plant equipment solder joint aging detection mainly relies on visual inspection, X-ray inspection and ultrasonic inspection. Among them, visual inspection (for example, surface inspection of solder joints through microscopes or cameras) can only detect obvious physical defects, but cannot detect internal damage; X-ray inspection is difficult to detect small cracks and transverse fractures between solder joints and circuit boards (for example, solder joint desoldering), and manual re-inspection is required; ultrasonic inspection detects internal defects of solder joints through ultrasonic reflection, but the effect of detecting solder joints with complex structures is not good.

DETAILED DESCRIPTION

[0013] 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 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.

[0014] The method for detecting aging of welding points of nuclear power plant equipment provided in this embodiment can be applied to Figure 1 In an application environment, a client communicates with a server. The client includes but is not limited to various personal computers, laptops, smart phones, tablet computers, and portable wearable devices. The server can be implemented with an independent server or a server cluster consisting of multiple servers.

[0015] In one embodiment, if Figure 2 As shown, a method for detecting aging of solder joints in nuclear power plant equipment is provided. Figure 1 The server in the example is used as an example to illustrate, including the following steps S10-S20: S10, receiving a nuclear power plant equipment weld aging detection request; the nuclear power plant equipment weld aging detection request includes a target weld and a weld detection mode.

[0016] Understandably, the request for aging detection of weld points of nuclear power plant equipment refers to a request for aging detection of weld points in nuclear power plant equipment. It should be understood that the request for aging detection of weld points of nuclear power plant equipment is generated according to the requirements of safe operation of nuclear power plants. Generally, nuclear power plants will perform aging detection of weld points of nuclear power plant equipment according to a predetermined maintenance plan; secondly, during the operation of the equipment, when the nuclear power plant monitoring system detects abnormal signals or parameter changes in nuclear power plant equipment, it may also trigger the nuclear power plant monitoring system to request aging detection of specific weld points. The request for aging detection of weld points of nuclear power plant equipment includes detection information such as target weld points and weld point detection mode. Among them, the target weld point refers to the weld point that needs to be aging detected, including weld point information such as weld point location and number. It should be understood that in the operation of nuclear power plants, different weld point detection modes are required to perform aging detection on target weld points for different aging detection purposes. Among them, the weld point detection mode refers to the mode of aging detection of target weld points. For example, the weld point detection mode includes the non-destructive detection mode and destructive detection mode mentioned later.

[0017] S20. Determine a solder joint detection strategy for the target solder joint according to the solder joint detection mode, and perform aging detection on the target solder joint using the solder joint detection strategy to obtain an aging detection result.

[0018] It is understandable that, since different detection modes correspond to the aging detection purposes for different purposes, different detection modes are correspondingly provided with corresponding solder joint detection strategies. For example, the solder joint detection strategy includes the non-destructive detection strategy and the destructive detection mode mentioned later. After determining the solder joint detection strategy, the target solder joint is subjected to aging detection using the determined solder joint detection strategy, and the detection data obtained during the aging detection process is recorded, such as solder joint electrical characteristic data, solder joint image data (crack size), solder joint tensile data (deformation pressure, fracture stress), etc. Then, aging analysis is performed based on the obtained detection data to obtain the aging detection result. Among them, the aging detection result refers to the result used to indicate whether the target solder joint is aged.

[0019] Optionally, the weld detection mode includes a nondestructive detection mode; the aging detection result includes a nondestructive aging detection result; understandably, the nondestructive detection mode refers to an aging detection mode that does not damage the target weld. For example, when a nuclear power plant performs aging detection on welds of nuclear power plant equipment according to a predetermined maintenance plan, the target welds of the nuclear power plant equipment can be subjected to aging detection through a nondestructive detection mode. If the aging detection result of the target weld of the nuclear power plant equipment indicates that the target weld is not aged, the nuclear power plant equipment corresponding to the target weld can continue to be put into use.

[0020] Further, in step S20, that is, determining a solder joint detection strategy of the target solder joint according to the solder joint detection mode, and performing aging detection on the target solder joint using the solder joint detection strategy to obtain an aging detection result, including: S21, when the solder joint detection mode is the non-destructive detection mode, determining the solder joint detection strategy for performing aging detection on the target solder joint as a non-destructive detection strategy; the non-destructive detection strategy refers to performing non-destructive aging detection on the target solder joint by using electrical characteristic detection and image detection; S22, performing non-destructive aging testing on the target solder joint by using the electrical characteristic testing and the image testing to obtain a non-destructive aging testing result.

[0021] It can be understood that the nondestructive testing mode and the nondestructive testing strategy are in a corresponding relationship. When the solder joint detection mode is the nondestructive testing mode, the solder joint detection strategy for performing aging detection on the target solder joint is correspondingly determined as the nondestructive testing strategy. Here, the nondestructive testing strategy refers to performing nondestructive aging detection on the target solder joint using electrical characteristic detection and image detection. Among them, electrical characteristic detection refers to a detection method for determining whether the target solder joint has been aged by obtaining electrical characteristic data of the target solder joint (including the first electrical characteristic data and the first electrical characteristic data mentioned later). Image detection refers to a detection method for determining whether the target solder joint has been aged by obtaining image data of the target solder joint (for example, obtaining image data of the target solder joint by infrared thermal imaging, and observing the internal situation of the target solder joint). The nondestructive aging detection result refers to the result obtained by performing aging detection on the target solder joint by the nondestructive testing strategy. The nondestructive testing strategy takes into account the electrical characteristics and internal situation of the target solder joint, performs aging analysis on the target solder joint based on the electrical characteristics and internal situation of the target solder joint, improves the accuracy of aging detection, and thus improves the efficiency of aging detection.

[0022] Optionally, in step S22, that is, performing nondestructive aging detection on the target solder joint by using the electrical characteristic detection and the image detection to obtain a nondestructive aging detection result includes: S221, acquiring first electrical characteristic data of the target solder joint by the electrical characteristic detection, and acquiring first image data of the target solder joint by the image detection; S222. Determine whether the target solder joint is in an aging state according to the first electrical characteristic data and the first image data, and obtain a non-destructive aging detection result.

[0023] It is understandable that the first electrical characteristic data refers to the electrical characteristic data of the target solder joint, such as electrical data such as capacitance, resistance, and inductance. The first image data refers to an image obtained by photographing or filming the target solder joint through a non-destructive testing strategy. For example, an image of the target solder joint is obtained through infrared thermal imaging. It should be understood that whether the target solder joint is aged can be determined based on the first electrical characteristic data and the first image data, and a determination result of whether the target solder joint is aged can be obtained, that is, a non-destructive aging test result is obtained.

[0024] Optionally, the nondestructive aging test result includes two results: the target solder joint is in a first aging state and the target solder joint is in a first normal state; understandably, the first aging state refers to the target solder joint being in an aged state. The first normal state refers to the target solder joint being in a non-aged state and being able to work normally.

[0025] Further, in step S222, that is, judging whether the target solder joint is in an aging state according to the first electrical characteristic data and the first image data, and obtaining a non-destructive aging detection result includes: S223, obtaining a first electrical characteristic result for characterizing whether the target solder joint is aged according to the first electrical characteristic data; understandably, the electrical characteristics of the target solder joint are measured and analyzed, including measuring electrical parameters such as resistance, capacitance or conductivity of the solder joint, and by comparing these electrical parameters with standard values ​​of the solder joint in a standard state, a preliminary judgment on whether the solder joint is aged can be obtained. If the electrical characteristic data deviates from the normal range, it may indicate that the solder joint is aged.

[0026] S224. Obtain a first image result for characterizing whether the target solder joint is aged according to the first image data; understandably, processing and analyzing the image data of the target solder joint includes acquiring an image of the solder joint using visual inspection technology, such as an optical microscope, infrared thermal imaging, or X-ray imaging. By analyzing the image data, the surface or internal condition of the solder joint can be observed, such as whether the surface or internal condition has cracks, corrosion, or deformation, so as to determine whether the solder joint is aged.

[0027] S225. When the first electrical characteristic result or the first image result indicates that the target solder joint is aged, determine that the target solder joint is in a first aging state; understandably, if any one of the first electrical characteristic result or the first image result indicates that the target solder joint is aged, then it can be determined that the solder joint is in an aged state, which means that the performance of the target solder joint may have deteriorated, which may cause the nuclear power plant equipment to fail and requires immediate repair or replacement to improve the safety of nuclear power plant operation.

[0028] S226. When both the first electrical characteristic result and the first image result indicate that the target solder joint is not aged, determine that the target solder joint is in a first normal state. Understandably, if both the first electrical characteristic result and the first image result indicate that the solder joint has no signs of aging, then it can be determined that the target solder joint is in a normal state, which means that the performance of the target solder joint meets working expectations and does not require immediate repair or replacement. Through the first electrical characteristic and the first image data, the state of the target solder joint can be more accurately evaluated, thereby ensuring the safe operation of the nuclear power plant.

[0029] Optionally, in step S224, that is, obtaining a first image result for characterizing whether the target solder joint is aged according to the first image data, includes: S2241. Extract aging features from the first image data using a solder joint aging recognition model to obtain aging features from the first image data. It is understandable that the solder joint aging recognition model refers to a trained deep learning model, such as a neural network or a convolutional neural network (CNN). It should be understood that by training the image data containing solder joint aging features (such as cracks, corrosion, deformation, etc.) and the corresponding normal solder joint image data, the key features of solder joint aging (such as pixel value, texture, shape, etc.) are identified and learned using the feature extraction technology of the initial solder joint aging recognition model to obtain a trained solder joint aging recognition model. The solder joint aging recognition model is used to identify and extract features of target solder joint aging from image data, and then determine whether the target solder joint has aging. Aging feature extraction refers to the process of extracting aging features from the first image data to obtain aging features, including image preprocessing (such as denoising, contrast enhancement), feature detection (such as edge detection, spot detection), and feature quantization (such as using a histogram, a co-occurrence matrix, etc.). Aging features refer to features of target solder joint aging, such as pixel value, texture, shape, etc.

[0030] S2242: Perform aging recognition on the first image data according to the aging characteristics to obtain the first image result.

[0031] Understandably, after the aging features are extracted, the solder joint aging recognition model will use these aging features to perform aging recognition on the target solder joints in the image, and determine whether the target solder joints are aged by the classifier in the solder joint aging recognition model to obtain the first image result. In this way, the solder joint aging recognition model can quickly and accurately identify potential solder joint aging problems, so that corresponding maintenance measures can be taken to ensure the safe operation of nuclear power plant equipment.

[0032] Optionally, the first electrical characteristic data includes capacitance data and / or resistance data; understandably, the capacitance data refers to the capacitance value of the target solder joint obtained by a capacitance measurement tool, and the resistance data refers to the resistance value of the target solder joint obtained by a resistance measurement tool.

[0033] Further, in step S223, that is, obtaining a first electrical characteristic result for characterizing whether the target solder joint is aged according to the first electrical characteristic data includes: S2231. Obtain a preset capacitance value corresponding to the capacitance data and / or a preset resistance value corresponding to the resistance data; understandably, the preset capacitance value refers to the standard capacitance value of the target solder joint under normal conditions, and the preset resistance value refers to the standard resistance value of the target solder joint under normal conditions. These preset values ​​are usually based on the material, design specifications, historical performance data or industry standards of the solder joint, and the preset values ​​are used as a comparison benchmark for subsequent aging evaluation.

[0034] S2232. Determine whether the capacitance data is greater than the preset capacitance value and / or whether the resistance data is greater than the preset resistance value; understandably, by comparing the capacitance data and / or resistance data of the target solder joint actually measured with the preset standard value, it can be determined whether the actual measurement value exceeds the normal range.

[0035] S2233. When the capacitance data is greater than the preset capacitance value and / or the resistance data is greater than the preset resistance value, generate a first electrical characteristic result indicating that the target solder joint is in a first aging state. Understandably, when the capacitance of the target solder joint increases, it may be due to material degradation, crack formation or other structural changes, resulting in a decrease in the insulation performance of the solder joint. When the resistance of the target solder joint increases, it may be due to poor contact, material oxidation or other forms of electrical connection degradation. Therefore, if the measured capacitance data is greater than the preset capacitance value, or the measured resistance data is greater than the preset resistance value, it usually indicates that the electrical performance of the target solder joint has changed. In this case, a first electrical characteristic result indicating that the solder joint is in an aging state is generated. In this way, the aging problem of the target solder joint can be effectively identified, so that corresponding measures can be taken, such as further testing, repair or replacement, to ensure the reliability and safety of the equipment. This process is an important part of nuclear power plant equipment maintenance and fault prevention.

[0036] Optionally, the weld detection mode includes a destructive detection mode; the aging detection result includes a destructive aging detection result; understandably, the destructive detection mode refers to an aging detection mode that damages the target weld. For example, during the operation of the equipment, if the nuclear power plant monitoring system detects an abnormal signal or parameter change in the nuclear power plant equipment, the target weld of the nuclear power plant equipment can be subjected to aging detection through a destructive detection mode. When the destructive aging detection result indicates that the target weld is aged, other nuclear power plant equipment of the corresponding batch of the nuclear power plant equipment needs to be inspected, repaired or replaced. On the contrary, when the destructive aging detection result indicates that the target weld is not aged, other nuclear power plant equipment of the corresponding batch of the nuclear power plant equipment can continue to be used.

[0037] Further, in step S20, that is, determining a solder joint detection strategy of the target solder joint according to the solder joint detection mode, and performing aging detection on the target solder joint using the solder joint detection strategy to obtain an aging detection result, including: S23, when the solder joint detection mode is the destructive detection mode, determining the solder joint detection strategy for performing aging detection on the target solder joint as a destructive detection strategy; the destructive detection strategy refers to performing destructive aging detection on the target solder joint by using electrical characteristic detection, image detection and tension detection; S24, performing a destructive aging test on the target solder joint by using the electrical characteristic test, the image test and the tension test to obtain a destructive aging test result.

[0038] It can be understood that the destructive detection mode corresponds to the destructive detection mode. When the solder joint detection mode is the destructive detection mode, the solder joint detection strategy for performing aging detection on the target solder joint is correspondingly determined as the destructive detection strategy. Here, the destructive detection strategy refers to performing destructive aging detection on the target solder joint using electrical characteristic detection, image detection and tensile force detection. Among them, electrical characteristic detection refers to a detection method for determining whether the target solder joint has been aged by obtaining electrical characteristic data of the target solder joint. Image detection refers to a detection method for determining whether the target solder joint has been aged by obtaining image data of the target solder joint (for example, obtaining image data of the target solder joint by infrared thermal imaging, and observing the internal situation of the target solder joint). Tensile force detection is a mechanical property test method used to evaluate the performance of a material or component when subjected to a tensile force. Here, the maximum tensile force that the target solder joint can currently withstand can be determined by tensile force detection, which is used to evaluate the aging degree of the solder joint. The destructive aging detection result refers to the result obtained by performing aging detection on the target solder joint through a destructive detection strategy. The destructive detection strategy takes into account the electrical characteristics, internal conditions and fracture conditions of the target solder joint when external force is applied to the target solder joint. Aging analysis is performed based on the electrical characteristics, internal conditions and fracture conditions of the target solder joint when external force is applied to improve the accuracy of aging detection, thereby improving the efficiency of aging detection.

[0039] Optionally, in step S24, that is, performing a destructive aging test on the target solder joint by using the electrical characteristic test, the image test and the tension test to obtain a destructive aging test result includes: S241, acquiring second electrical characteristic data of the target welding point through the electrical characteristic detection, acquiring second image data of the target welding point through the image detection, and acquiring tension data of the target welding point through the tension detection; S242: Determine whether the target solder joint is in an aging state according to the second electrical characteristic data, the second image data and the tension data, and obtain a destructive aging detection result.

[0040] It is understandable that the second electrical characteristic data refers to the electrical characteristic data of the target solder joint, such as electrical data such as capacitance, resistance and inductance. The second image data refers to the image obtained by shooting or photographing the target solder joint through a destructive detection strategy. For example, an image of the target solder joint is obtained by infrared thermal imaging. The tensile data is the key data recorded when a tensile force is applied to the target solder joint until the target solder joint breaks or reaches a predetermined tensile value, including the applied force, the deformation of the sample, and the force value when the solder joint breaks. It should be understood that whether the target solder joint is aged can be judged based on the second electrical characteristic data, the second image data and the tensile data, and a judgment result of whether the target solder joint is aged can be obtained, that is, a destructive aging detection result is obtained.

[0041] Optionally, the destructive aging detection result includes two results: the target solder joint is in a second aging state and the target solder joint is in a second normal state; understandably, the second aging state refers to the target solder joint being in an aged state. The second normal state refers to the target solder joint being in a non-aged state and being able to work normally.

[0042] Further, in step S242, that is, judging whether the target solder joint is in an aging state according to the second electrical characteristic data, the second image data and the tension data, and obtaining a destructive aging detection result includes: S243, according to the second electrical characteristic data, obtain a second electrical characteristic result for characterizing whether the target solder joint is aged; understandably, the electrical characteristics of the target solder joint are measured and analyzed, including measuring electrical parameters such as resistance, capacitance or conductivity of the solder joint, and by comparing these electrical parameters with standard values ​​of the solder joint in the standard state, a preliminary judgment on whether the solder joint is aged can be obtained. If the electrical characteristic data deviates from the normal range, it may indicate that the solder joint is aged.

[0043] S244, obtaining a second image result for characterizing whether the target solder joint is aged according to the second image data; understandably, processing and analyzing the image data of the target solder joint includes acquiring an image of the solder joint using visual inspection technology, such as an optical microscope, infrared thermal imaging, or X-ray imaging. By analyzing the image data, the surface or internal condition of the solder joint can be observed, such as whether the surface or internal condition is cracked, corroded, or deformed, so as to determine whether the solder joint is aged.

[0044] S245. Perform a fracture characteristic analysis on the tensile data to obtain a second tensile result for characterizing whether the target solder joint is aged. It can be understood that the fracture characteristic analysis refers to analyzing the tensile data recorded in the tensile test to identify key indicators when the target solder joint breaks, and the key indicators include fracture stress, fracture elongation, cross-sectional shrinkage, fracture mode (such as ductile fracture or brittle fracture), etc.

[0045] S246: When the second electrical characteristic result, the second image result or the tensile force result indicates that the target solder joint is aged, the target solder joint is determined to be in the second aging state; understandably, if any test result (the second electrical characteristic result, the second image result or the tensile force result) indicates that the solder joint has aged, then the solder joint can be determined to be in the second aging state. In this way, based on the comprehensive evaluation of multiple parameters of the target solder joint, the accuracy and reliability of aging detection are ensured.

[0046] S247: When the second electrical characteristic result, the second image result, and the tension result all indicate that the target solder joint is not aged, determine that the target solder joint is in a second normal state.

[0047] Understandably, if all test results (second electrical characteristic results, second image results, and tensile results) indicate that the solder joint has no signs of aging, it means that the target solder joint currently performs well and has not experienced aging that causes performance degradation, then the solder joint can be determined to be in the second normal state. In this way, the actual state of the solder joint can be more accurately identified, thereby providing a scientific basis for maintenance and replacement decisions of nuclear power plant equipment. This method helps to ensure the safe operation of nuclear power plants and extend the service life of equipment. For example, during the operation of the equipment, if the nuclear power plant monitoring system detects abnormal signals or parameter changes in the nuclear power plant equipment, the target solder joint of the nuclear power plant equipment can be subjected to aging detection in a destructive detection mode. If the destructive aging detection result indicates that the target solder joint is aged, then other nuclear power plant equipment corresponding to the batch of the nuclear power plant equipment needs to be further tested, repaired, or replaced. On the contrary, if the destructive aging detection result indicates that the target solder joint is not aged, other nuclear power plant equipment corresponding to the batch of the nuclear power plant equipment can be used continuously.

[0048] Optionally, in step S245, that is, performing fracture characteristic analysis on the tensile force data to obtain a second tensile force result for characterizing whether the target solder joint is aged includes: S2451, performing fracture characteristic analysis on the target welding point according to the tensile force data to obtain fracture stress; S2452, determining whether the fracture stress is less than or equal to the preset stress; S2453. When the fracture stress is less than or equal to the preset stress, generate a second tensile force result indicating that the target solder joint is in a second aging state.

[0049] Understandably, the fracture stress refers to the stress that the weld is subjected to when it breaks. The preset stress value is a safety threshold determined based on the weld design specification, material properties or industry standards. It should be understood that if the fracture stress is less than or equal to the preset stress, this indicates that the fracture performance of the target weld may not meet the safety requirements. When the fracture stress is less than or equal to the preset stress, a second tensile result indicating that the weld is in an aged state will be generated, indicating that the weld may be at risk of breaking when subjected to normal working loads. In this way, possible aging problems of the target weld can be effectively identified, and decision support can be provided for the maintenance and replacement of nuclear power plant equipment. This process helps ensure the safe operation of nuclear power plants and prevent potential failures due to weld aging.

[0050] In embodiments S10-S20, a request for aging detection of weld points of nuclear power plant equipment is received; the request for aging detection of weld points of nuclear power plant equipment includes a target weld point and a weld point detection mode; according to the weld point detection mode, a weld point detection strategy for the target weld point is determined, and an aging detection is performed on the target weld point using the weld point detection strategy to obtain an aging detection result. In this way, the target weld point can be flexibly analyzed for aging through detection strategies of different detection modes, thereby improving the accuracy of aging detection and thereby improving the efficiency of aging detection.

[0051] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0052] In one embodiment, a device for detecting aging of solder joints of nuclear power plant equipment is provided, and the device for detecting aging of solder joints of nuclear power plant equipment corresponds one-to-one to the method for detecting aging of solder joints of nuclear power plant equipment in the above embodiment.
