Description

Technical Field

[0001] This invention belongs to the field of electromechanical installation and testing technology, specifically an industrial equipment electromechanical installation status monitoring and early warning system. Background Technology

[0002] In the installation of industrial equipment, cable crimp terminals are common and critical connection components, and their installation quality directly affects the reliability and safety of equipment operation. Currently, common methods for inspecting the quality of cable crimp terminals mainly rely on manual pulling, continuity testing, or cross-sectional sampling. These methods suffer from low efficiency, are time-consuming and labor-intensive, are destructive, cannot achieve full coverage or non-destructive inspection, and have limitations such as insufficient sampling and lack of data traceability. Furthermore, some existing technologies use infrared thermography, which typically judges crimping based solely on the temperature rise threshold under a single steady-state current excitation. This method cannot accurately identify defects in the crimping process. In addition, existing infrared thermography detection schemes usually only rely on steady-state temperature values, making it difficult to detect minute defects or hidden voids, loose connections, etc., resulting in insufficient precision in monitoring the electromechanical installation status of industrial equipment. Therefore, this paper proposes an industrial equipment electromechanical installation status monitoring and early warning system. Summary of the Invention

[0003] The purpose of this invention is to provide an industrial equipment electromechanical installation status monitoring and early warning system, which solves the technical problem that the inability to accurately identify defects in the crimping process leads to insufficient accuracy in monitoring the electromechanical installation status of industrial equipment, resulting in inaccurate monitoring of the electromechanical installation status of industrial equipment.

[0004] An industrial equipment electromechanical installation status monitoring and early warning system, comprising:

[0005] The temperature distribution sequence data acquisition module acquires the temperature distribution sequence data corresponding to each cable crimp terminal at multiple preset acquisition times t within a preset acquisition time period, where t represents different preset acquisition times.

[0006] The temperature gradient uniformity acquisition module generates a three-dimensional temperature point cloud dataset corresponding to each cable crimp terminal. It analyzes the three-dimensional temperature point cloud dataset to obtain the temperature gradient uniformity corresponding to each cable crimp terminal and generates an air pressure early warning signal based on the temperature gradient uniformity.

[0007] The temperature propagation path acquisition module analyzes the temperature measurement points of each cable crimp terminal at each preset acquisition time t hourly, obtains the heat core corresponding to each cable crimp terminal at each preset acquisition time t, and obtains the temperature propagation path corresponding to each cable crimp terminal based on the heat core.

[0008] The heat diffusion offset value acquisition module analyzes the temperature expansion path and geometric center coordinates of each cable crimp terminal to obtain the heat diffusion offset value of each cable crimp terminal, and generates an eccentricity warning signal based on the heat diffusion offset value.

[0009] The installation defect signal generation module analyzes and judges the number of cable crimp terminals that simultaneously have air pressure warning signals and eccentricity warning signals to generate installation defect signals.

[0010] As a further aspect of the present invention, the specific method for obtaining the temperature gradient uniformity at each cable crimp terminal is as follows:

[0011] First, randomly select one of the various cable crimp terminals as the target terminal; divide the three-dimensional space occupied by the target terminal into a series of regular cubic units, and label these cubes as voxels corresponding to the target terminal; for each voxel, calculate the average temperature corresponding to all temperature measurement points within it, and thus obtain the temperature value corresponding to each voxel of the target terminal; use the standard deviation of the temperature value corresponding to each voxel of the target terminal as the temperature gradient uniformity D1 corresponding to the target terminal; use the same analysis method as for obtaining the temperature gradient uniformity corresponding to the target terminal to analyze the temperature distribution sequence data of the remaining cable crimp terminals, and thus obtain the temperature gradient uniformity Dj corresponding to each cable crimp terminal, where j represents different cable crimp terminals, j = 1, 2, ..., g, where g is the total number of cable crimp terminals, g is a positive integer, and g ≥ 2.

[0012] As a further aspect of the present invention, the specific method for determining the generation of the air pressure warning signal is as follows:

[0013] When the gradient uniformity is less than the preset value Y1, no action is taken; when the gradient uniformity is greater than or equal to the preset value Y1, an air pressure warning signal is generated.

[0014] As a further aspect of the present invention, the specific method for obtaining the temperature propagation path corresponding to each cable crimp terminal is as follows:

[0015] First, one cable crimp terminal is randomly selected as the analysis terminal. The three-dimensional space occupied by the analysis terminal is divided into a series of regular cubic units, and these cubes are marked as different voxels corresponding to the analysis terminal. The temperature measurement points corresponding to the analysis terminal at each preset acquisition time t are obtained. The center point of the voxel corresponding to the temperature measurement point at each preset acquisition time t is taken as the heat core Ht corresponding to the analysis terminal at each preset acquisition time t. Then, the coordinates of the center point of the voxel are taken as the heat core coordinates Ht(Xt,Yt,Zt). The heat cores Ht corresponding to the analysis terminal at each preset acquisition time t are connected sequentially from front to back according to the preset acquisition time t to obtain the temperature extension path L1 corresponding to the analysis terminal. The same analysis method as obtaining the temperature extension path L1 corresponding to the analysis terminal is used to analyze the temperature measurement points corresponding to the remaining cable crimp terminals at each preset acquisition time t to obtain the temperature extension path Lj corresponding to each cable crimp terminal.

[0016] As a further aspect of the present invention: if the temperature measurement point is located on the same boundary line of two voxels, then the midpoint of the line connecting the center points of the two voxels is taken as the heat core of the corresponding temperature measurement point.

[0017] As a further aspect of the present invention, the specific method for obtaining the thermal diffusion offset value corresponding to each cable crimp terminal is as follows:

[0018] During the electromechanical installation or design phase, the geometric center coordinates Cj(xj,yj,zj) of each cable crimp terminal are obtained through the CAD model. The heat core coordinates Ht(Xt,Yt,Zt) of each preset acquisition time t in the temperature extension path L1 corresponding to the analysis terminal are obtained from the temperature extension path acquisition module. The average value of the heat core coordinates Ht(Xt,Yt,Zt) corresponding to each preset acquisition time t is obtained and used as the path position coordinates W(Xp,Yp,Zp) of the temperature extension path of the analysis terminal. At the same time, the geometric center coordinates E(Ex,Ey,Ez) of the analysis terminal are obtained. The vector magnitude |V| between the geometric center E of the analysis terminal and the path position W is calculated and used as the thermal diffusion offset value F1 of the analysis terminal. The same analysis method as that used to obtain the thermal diffusion offset value of the analysis terminal is used to analyze the temperature extension path and geometric center coordinates of each remaining cable crimp terminal at each preset acquisition time t, thereby obtaining the thermal diffusion offset value Fj of each cable crimp terminal.

[0019] As a further aspect of the present invention: the specific method for generating an eccentricity warning signal based on the thermal diffusion offset value is as follows:

[0020] If the thermal diffusion offset at the cable crimp terminal is less than 2mm, no action is taken; if the thermal diffusion offset is greater than or equal to 2mm, an eccentricity warning signal is generated.

[0021] As a further aspect of the present invention: the specific method for obtaining the vector magnitude |V| between the geometric center E of the analysis terminal and the path position W is as follows:

[0022] Through the formula: The vector magnitude |V| between the geometric center E of the analysis terminal and the path position W is calculated.

[0023] As a further aspect of the present invention, the specific method for determining the generation of installation defect signals is as follows:

[0024] The number h of cable crimp terminals that simultaneously have both air pressure warning signals and eccentricity warning signals is obtained. The ratio between h and the total number of cable crimp terminals g is calculated. If the ratio is greater than a preset value of 3 / 5, an installation defect signal is generated; otherwise, no action is taken.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) In this invention, the temperature distribution sequence data of each cable crimping terminal at different preset acquisition times are converted and fused into a unified three-dimensional coordinate system to form a three-dimensional temperature point cloud dataset. For each cable crimping terminal, the average temperature in each voxel is calculated, and the standard deviation of the temperature value is used as the temperature gradient uniformity. When the temperature gradient uniformity is less than the preset value, it indicates that the crimping quality is good; otherwise, there may be problems such as air pressure, bias pressure or poor connection.

[0027] (2) In this invention, by analyzing the heat core of the cable crimp terminal at each preset acquisition time and connecting them to form a temperature expansion path, the heat diffusion of the cable crimp terminal can be further evaluated by analyzing the temperature expansion path. By obtaining the temperature expansion path, the system can track the dynamic diffusion process of heat inside the terminal. The real-time tracking of the heat core and the calculation of the average position can reflect the stability and diffusion mode of the heat source, further enhancing the ability to identify defects.

[0028] (3) By calculating the temperature gradient uniformity and heat diffusion offset value, the present invention can deeply evaluate the heat distribution and heat diffusion dynamics inside the crimp terminal. This enables the system to identify electromechanical installation defects that are difficult to detect by traditional methods. The installation defect signal performs a macroscopic evaluation of the overall installation quality, determines and generates air pressure warning signal and eccentricity warning signal, and promptly alerts the installation defects, avoiding equipment malfunctions and avoiding false alarms and missed alarms. This provides a more intelligent and reliable basis for maintenance decisions and improves the accuracy of monitoring the electromechanical installation status of industrial equipment. Attached Figure Description

[0029] Figure 1 This is a schematic diagram of the system framework structure of the present invention. Detailed Implementation

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 This application provides an industrial equipment electromechanical installation status monitoring and early warning system, including:

[0032] The temperature distribution sequence data acquisition module is equipped with infrared thermal imaging detection devices of the same specifications at each cable crimping terminal of the electromechanical equipment. The resolution of the infrared thermal imaging detection devices is ≥320×240 and the frame rate is ≥30Hz. When the electromechanical equipment is powered on, the module acquires the temperature distribution sequence data corresponding to each cable crimping terminal at multiple preset acquisition times t within a preset acquisition time. The preset acquisition time is controlled within 5 to 10 seconds, and the preset acquisition time here is 6 seconds. Multiple preset acquisition times t are obtained within the preset acquisition time, and the time interval between each preset acquisition time t is 0.2s. t represents different preset acquisition times, t=1, 2, …, n, where n is the number of preset acquisition times, n is a positive integer, and n≥2.

[0033] The temperature gradient uniformity acquisition module converts and merges the temperature distribution sequence data corresponding to each cable crimp terminal at different preset acquisition times t into a unified three-dimensional coordinate system, forming a three-dimensional temperature point cloud dataset corresponding to each cable crimp terminal. The module then analyzes this dataset to obtain the temperature gradient uniformity at each cable crimp terminal. Specifically, the module does this as follows:

[0034] First, randomly select one of the various cable crimp terminals as the target terminal; divide the three-dimensional space occupied by the target terminal into a series of regular cubic units, and mark these cubes as the voxels corresponding to the target terminal; for each voxel, calculate the average temperature corresponding to all temperature measurement points inside it, and then obtain the temperature value corresponding to each voxel of the target terminal; use the standard deviation of the temperature value corresponding to each voxel of the target terminal as the temperature gradient uniformity D1 corresponding to the target terminal.

[0035] Then, the temperature distribution sequence data of each remaining cable crimp terminal after removing the target terminal is iterated. The same analysis method as that used to obtain the temperature gradient uniformity corresponding to the target terminal is adopted to analyze the temperature distribution sequence data of each remaining cable crimp terminal, thereby obtaining the temperature gradient uniformity Dj corresponding to each cable crimp terminal, where j refers to different cable crimp terminals, j = 1, 2, ..., g, where g is the total number of cable crimp terminals, g is a positive integer, and g ≥ 2;

[0036] When the gradient uniformity is less than the preset value Y1, it indicates that the temperature distribution of the corresponding cable crimp terminal is uniform and the crimping quality is good. When the gradient uniformity is greater than or equal to the preset value Y1, it indicates that there is a large difference in the temperature distribution of the corresponding cable crimp terminal, which may be due to air pressure, bias pressure or poor connection. In this case, an air pressure warning signal is generated. The specific value of the preset value Y1 is determined by relevant personnel according to actual needs.

[0037] An ideal cable crimp terminal will produce a relatively uniform temperature distribution, so the gradient uniformity value will be small, and heat will diffuse evenly from the resistance point outward. Defects, loose connections, voids, or local oxidation in the cable crimp terminal will cause heat to concentrate in a specific area, resulting in a very uneven temperature distribution and thus a large gradient uniformity value. For example, if there is a void in the crimp, the current will pass through a smaller effective contact area, causing the resistance in that area to increase, the temperature to rise abnormally, and the overall temperature field to fluctuate more.

[0038] The temperature distribution sequence data of each cable crimp terminal at different preset acquisition times are converted and fused into a unified three-dimensional coordinate system to form a three-dimensional temperature point cloud dataset. For each cable crimp terminal, the mean temperature in each voxel is calculated, and the standard deviation of the temperature value is used as the temperature gradient uniformity. When the temperature gradient uniformity is less than the preset value, it indicates that the crimping quality is good; otherwise, there may be problems such as air pressure, bias pressure or poor connection.

[0039] The temperature propagation path acquisition module, based on each preset acquisition time t, analyzes the temperature measurement points of each cable crimp terminal at each preset acquisition time t in the corresponding three-dimensional temperature point cloud dataset. This analysis yields the heat core corresponding to each cable crimp terminal at each preset acquisition time t. Based on the analysis of these heat cores, the temperature propagation path corresponding to each cable crimp terminal is obtained. Specifically, the method is as follows:

[0040] The specific method for obtaining the temperature propagation path corresponding to each cable crimp terminal is as follows:

[0041] First, randomly select one of the various cable crimp terminals as the analysis terminal. Divide the three-dimensional space occupied by the analysis terminal into a series of regular cubic units, and mark these cubes as different voxels corresponding to the analysis terminal. Obtain the temperature measurement points corresponding to the analysis terminal at each preset acquisition time t. Take the center point of the voxel where the temperature measurement point is located at each preset acquisition time t as the heat core Ht corresponding to the analysis terminal at each preset acquisition time t. Then, take the coordinates of the center point of the voxel as the heat core coordinates Ht(Xt,Yt,Zt). If the temperature measurement point is located on the same boundary line of two voxels, take the midpoint of the line connecting the center points of the two voxels as the heat core of the corresponding temperature measurement point. Connect the heat cores Ht corresponding to the analysis terminal at each preset acquisition time t in sequence from front to back according to the preset acquisition time t to obtain the temperature extension path L1 corresponding to the analysis terminal. Use the same analysis method as to obtain the temperature extension path L1 corresponding to the analysis terminal to analyze the temperature measurement points corresponding to the remaining cable crimp terminals at each preset acquisition time t to obtain the temperature extension path Lj corresponding to each cable crimp terminal.

[0042] By introducing 3D thermal field reconstruction, 2D thermal imaging data is transformed into 3D temperature point clouds and subjected to voxel analysis. This enables the system to locate and analyze internal defects in a spatial dimension, such as the specific location and degree of eccentricity of voids, providing richer data support for accurate diagnosis and repair. At each preset acquisition time, the heat core of the cable crimp terminal is analyzed and connected to form a temperature propagation path. By analyzing the temperature propagation path, the thermal diffusion of the cable crimp terminal is further evaluated. By acquiring the temperature propagation path, the system can track the dynamic diffusion process of heat inside the terminal. Real-time tracking of the heat core and calculation of its average position reflect the stability and diffusion pattern of the heat source, further enhancing the ability to identify defects.

[0043] The heat diffusion offset value acquisition module obtains the geometric center coordinates of each cable crimp terminal from the corresponding 3D temperature point cloud dataset. It then analyzes the temperature propagation path and geometric center coordinates of each cable crimp terminal to obtain the heat diffusion offset value for each terminal. Specifically, the module works as follows:

[0044] The specific method for obtaining the geometric center coordinates of each cable crimp terminal is as follows:

[0045] During the electromechanical installation or design phase, the geometric center coordinates Cj(xj,yj,zj) of each cable crimp terminal are obtained through CAD models or actual measurements. The geometric center coordinates are fixed reference points corresponding to each cable crimp terminal.

[0046] The specific method for obtaining the thermal diffusion offset value corresponding to each cable crimp terminal is as follows:

[0047] The heat core coordinates Ht(Xt,Yt,Zt) at each preset acquisition time t in the temperature extension path L1 corresponding to the analysis terminal are obtained from the temperature extension path acquisition module. The average value of the heat core coordinates Ht(Xt,Yt,Zt) at each preset acquisition time t is obtained, and then the average position of the heat core of the analysis terminal is obtained, which is used as the path position coordinates W(Xp,Yp,Zp) of the temperature extension path of the analysis terminal. At the same time, the geometric center coordinates E(Ex,Ey,Ez) corresponding to the analysis terminal are obtained from the geometric center coordinates Cj(xj,yj,zj) corresponding to each cable crimp terminal.

[0048] Based on the geometric center coordinates E(Ex,Ey,Ez) and path position coordinates W(Xp,Yp,Zp) of the analysis terminal, calculate the vector magnitude |V| between the geometric center E of the analysis terminal and the path position W, and use it as the thermal diffusion offset value F1 corresponding to the analysis terminal;

[0049] Through the formula: Calculate the vector magnitude |V| between the geometric center E of the analysis terminal and the path position W;

[0050] Using the same analysis method as the analysis terminal, the temperature expansion path and geometric center coordinates of each remaining cable crimp terminal at each preset acquisition time t are analyzed, thereby obtaining the heat diffusion offset value Fj corresponding to each cable crimp terminal.

[0051] When the thermal diffusion offset value at the cable crimp terminal is less than 2mm, it indicates that the corresponding cable crimp terminal is of good quality; if the thermal diffusion offset value is greater than or equal to 2mm, an eccentricity warning signal is generated, which clearly indicates that there is crimping eccentricity or obvious voids in the corresponding cable crimp terminal. This 2mm is an empirical threshold that can be adjusted according to actual application and accuracy requirements.

[0052] Example 2: As Example 2 of the present invention, in specific implementation, the technical solution of this example differs from that of Example 1 only in that this example also includes a defect signal generation module;

[0053] The installation defect signal generation module analyzes and judges the number of cable crimp terminals that simultaneously exhibit both air pressure warning signals and eccentricity warning signals to generate installation defect signals. The specific method is as follows:

[0054] The number of cable crimp terminals h that simultaneously have both air pressure warning signals and eccentricity warning signals is obtained. The ratio between h and the total number of cable crimp terminals g is calculated. If the ratio is greater than a preset value of 3 / 5, an installation defect signal is generated; otherwise, no action is taken.

[0055] By employing multi-dimensional thermal field data analysis and calculating temperature gradient uniformity and thermal diffusion offset values, the system can thoroughly assess the internal thermal distribution and heat diffusion dynamics of crimp terminals. This enables the system to identify defects that are difficult to detect using traditional methods, such as crimping eccentricity, micro-voids, localized oxidation, and loose connections. This improves the sensitivity and accuracy of defect identification and enhances the precision of monitoring the electromechanical installation status of industrial equipment.

[0056] By using installation defect signals to perform a macroscopic assessment of the overall installation quality, the system generates air pressure warning signals and eccentricity warning signals to promptly identify installation defects and prevent equipment malfunctions. This avoids false alarms and missed alarms, providing a more intelligent and reliable basis for maintenance decisions. The system can bind the identification results with information such as terminal number, installation time, and operator to form a digital quality archive, providing a data foundation for subsequent quality management, traceability, and optimization. The entire monitoring process does not require direct contact with cable crimp terminals, avoiding any form of damage to the equipment or connectors. It is suitable for online monitoring and large-scale surveys, and is especially suitable for industrial equipment with high reliability requirements.

[0057] Example 3: As Example 3 of the present invention, in specific implementation, compared with Example 1 and Example 2, the technical solution of this example is to combine the solutions of Example 1 and Example 2.

The formulas are derived from software simulations based on a large amount of collected data to obtain the most recent real-world results. The preset parameters and thresholds in the formulas are set by those skilled in the art according to the actual situation.

[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
