[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] It is understandable that in the prior art, the detection of the verticality of the copper electrolytic cathode plate mainly relies on manual measurement using mechanical devices, which is easily affected by human errors and environmental factors, resulting in low accuracy of the verticality detection results and unable to ensure the accuracy of the copper electrolytic cathode plate verticality detection.

[0030] To solve the above problems, the embodiment of the present invention obtains the standard cathode plate model of the copper electrolysis cathode plate, performs detection planning on the standard cathode plate model, and selects multiple key detection points; performs work monitoring on multiple online copper electrolytic cells, obtains work monitoring data, performs work abnormality identification, and selects abnormal copper electrolytic cells; performs cathode plate detection and point position identification on abnormal copper electrolytic cells, and obtains point position data of multiple key detection points; performs data preprocessing on the point position data, and fits the working cathode plate model; performs verticality detection and analysis on the working cathode plate model, generates verticality detection results, and performs result feedback display.

[0031] Figure 1 A flow chart of a method provided by an embodiment of the present invention is shown.

[0032] Specifically, the method for detecting the verticality of the cathode plate of copper electrolysis comprises the following steps: Step S101, obtaining a standard cathode plate model of a copper electrolysis cathode plate, performing detection planning on the standard cathode plate model, and selecting a plurality of key detection points.

[0033] In an embodiment of the present invention, by obtaining the internal numbering information of the copper electrolysis cathode plate, according to the internal numbering information, the standard cathode plate model is matched and downloaded from a preset internal model database, and then the point selection parameters including quantity, interval distance, etc. are obtained. According to the point selection parameters, the detection plan of point selection is performed on the standard cathode plate model, and multiple key detection points are selected so that the multiple key detection points meet the point selection parameters.

[0034] It can be understood that the standard cathode plate model can be a three-dimensional model.

[0035] Specifically, Figure 2 A flow chart of selecting multiple key detection points in the method provided by an embodiment of the present invention is shown.

[0036] Among them, in the preferred embodiment provided by the present invention, the obtaining of the standard cathode plate model of the copper electrolysis cathode plate, the detection planning of the standard cathode plate model, and the selection of multiple key detection points specifically include the following steps: Step S1011, obtaining the internal number information of the copper electrolysis cathode plate; Step S1012, matching and downloading a standard cathode plate model from a preset internal model database according to the internal number information; Step S1013, obtaining point selection parameters; Step S1014, performing inspection planning on the standard cathode plate model according to the point selection parameters, and selecting a plurality of key inspection points.

[0037] Among them, in the preferred embodiment provided by the present invention, the detection planning of the standard cathode plate model according to the point selection parameters and the selection of multiple key detection points specifically include the following steps: Step S101401, performing finite element simulation on a standard cathode plate model to generate surface stress distribution data, the surface stress distribution data including three-dimensional coordinates and stress values ​​of each point in the three-dimensional coordinates; Step S101402, using the first-order derivative to calculate the stress change rate at each point in the transverse and longitudinal directions, and using the second-order derivative to analyze the increase and decrease trend of the stress change rate at each point in the transverse and longitudinal directions according to the stress change rate; Step S101403, marking the area where the curvature change exceeds a preset threshold according to the increase and decrease trend, and obtaining a cathode plate surface distribution map with stress sensitive areas marked; Step S101404, obtaining the voltage and current monitoring data of the electrolytic cell, and converting the voltage and current data into the current density value of each candidate point according to the current distribution characteristics in the electrolytic cell; Step S101405, setting a safety threshold, calculating the current density gradient between adjacent candidate points, and comparing it with the safety threshold; using a logarithmic function to smooth the area where the gradient value exceeds the threshold, and then normalizing the current density gradients of all candidate points to obtain a normalized current density gradient score; Step S101406, obtaining historical fault records of the same type of cathode plates; Step S101407, dividing the cathode plate surface according to the coordinate grid, and calculating the number of historical faults that occurred in each grid unit; Step S101408, defining the highest number of faults as a reference value and normalizing it to obtain a normalized historical fault frequency coefficient of each point; Step S101409, according to the sensitivity of temperature change to material deformation and current distribution, obtain the real-time data of the current electrolyte temperature sensor, and give corresponding dynamic weights based on the electrolyte temperature change to the stress sensitive part, the current gradient part and the historical fault part; Step S101410, weighted fusion of the stress sensitive area mark, the normalized score of the current density gradient, and the normalized historical fault frequency coefficient with the corresponding dynamic weight to obtain a comprehensive score, and generate a priority point list according to the comprehensive score; Step S101411, based on the spatial distribution of the points and the priority ranking in the point list, the TSP optimization algorithm is used to generate the optimal detection path, and the points in the optimal detection path are taken as key detection points.

[0038] In the embodiment of the present invention, three key parameters, namely stress sensitivity, current density gradient and historical failure frequency, are introduced at the same time. Stress sensitivity can reflect the risk of structural deformation, current density gradient can characterize process abnormalities, and historical failure frequency can quantify reliability trends. Dynamic weights are used to achieve parameter importance grading. For example, the weight of stress items is automatically reduced under high temperature conditions to avoid overfitting. Compared with the traditional single indicator detection method, the detection rate can be effectively improved and the false alarm rate can be reduced.

[0039] In addition, by setting up adaptive dynamic adjustment, the weight coefficient is adjusted in real time according to the electrolyte temperature. When the temperature rises, the weight of the current density term increases to capture the abnormality of the electrolytic reaction, while the weight of the stress term decreases to avoid excessive attention to pseudo-defects caused by thermal expansion. It can adapt to different production environments without manual resetting of parameters, and achieve fully automatic tuning.

[0040] Finally, the optimal detection path is generated by comprehensively considering the spatial distribution of the points and the priority sorting in the point list. The points in the optimal detection path are taken as key detection points to improve the detection efficiency.

[0041] Furthermore, the method for detecting the verticality of the copper electrolysis cathode plate further comprises the following steps: Step S102, monitor the operation of multiple online copper electrolytic cells, obtain operation monitoring data, identify abnormal operation, and select abnormal copper electrolytic cells.

[0046] Among them, in the preferred embodiment provided by the present invention, the integration of the infrared monitoring data and the voltage and current data to generate the working monitoring data specifically includes the following steps: Step S102401, extracting the temperature value of each detection point in the electrolytic cell from the infrared monitoring data; Step S102402, calculating the degree of dispersion of the temperature distribution based on the mean of the temperature values ​​of all the detection points to obtain the temperature variance; Step S102403, obtaining the process cycle of the electrolysis process, and taking the position of the current time in the electrolysis cycle as a reference, generating a correction coefficient that fluctuates with time to obtain an environmental correction coefficient; Step S102403, extracting the current voltage value from the voltage and current data, and calculating the voltage offset rate according to the current voltage value and the reference voltage; Step S102404, calculating the current change rate according to the current values ​​monitored twice adjacently in the voltage and current data, and fusing the voltage offset rate and the current change rate to obtain the voltage and current dynamic coupling amount; Step S102405, calculating the influence of infrared sensor delay on temperature detection according to the temperature variance and the infrared sensor response time, and obtaining a delay anomaly index; Step S102406, substitute the environmental correction coefficient into the S-type growth function as a correction term, weight the voltage and current dynamic coupling quantity and the delay anomaly index, and use the correction term to correct it to obtain a comprehensive anomaly index.

[0047] Step S102407, the abnormal copper electrolytic cell can be directly selected based on the comprehensive abnormal index.

[0048] In an embodiment of the present invention, the infrared temperature discretization quantifies the local thermal field anomaly, and at the same time combines the voltage and current dynamic coupling to capture the electromagnetic field mutation, so as to realize the collaborative analysis of the thermal-electric dual physical field. Compared with the traditional single temperature or electrical parameter monitoring, the detection coverage is expanded to multiple types of faults such as electrolytic cell surface deformation, plate short circuit, electrolyte concentration imbalance, etc. And a periodic environmental correction coefficient is introduced to automatically compensate for the temperature difference between day and night or the interference of workshop air conditioning. And the correction coefficient is dynamically adjusted with the process cycle, without the need for manual intervention parameters, and is adapted to the three-shift continuous production scenario.
