In existing technologies, aluminum foil undergoes roughing, intermediate rolling, and finishing processes during rolling. However, current methods for tracking the rolling status of aluminum foil are insufficient for effectively monitoring its rolling quality and for providing feedback on the operating status of the rolling equipment to quickly and effectively resolve rolling-related problems. Summary of the Invention

[0007] As a further aspect of the present invention: the obtained front and back performance values ​​of the aluminum foil are weighted and calculated to obtain the aluminum foil performance values ​​before rolling and after rolling, respectively.

[0008] As a further aspect of the present invention: the performance value ZBC2 of the rolled aluminum foil is obtained, and the performance value ZBC2 of the rolled aluminum foil is compared with the performance threshold of the rolled aluminum foil.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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. Example 1

[0017] Please see Figure 1 As shown, the present invention is a video monitoring-based method for tracking the rolling state of aluminum foil, which can be executed by an aluminum foil rolling state tracking system; The aluminum foil rolling condition tracking method includes the following steps: Step 1: Obtain aluminum foil performance data during rough rolling; The aluminum foil performance data includes aluminum foil performance values ​​before rough rolling and aluminum foil performance values ​​after rough rolling. The method for obtaining the performance values ​​of aluminum foil includes the following steps: The surface crack value, surface scar value, and surface oxidation value of aluminum foil are obtained through a visual camera. The surface crack value is obtained by measuring the area of ​​cracks on the aluminum foil surface, the surface scar value is obtained by measuring the area of ​​scars on the aluminum foil surface, and the surface oxidation value is obtained by measuring the area of ​​abnormal color areas on the aluminum foil surface. The obtained surface crack value, surface scar value, and surface oxidation value of aluminum foil are weighted to obtain the rough rolling performance value of aluminum foil. In some embodiments, the surface crack value, surface scar value, and surface oxidation value of the aluminum foil are obtained by a vision camera and labeled as ZLc1, ZBc1, and ZYc1, respectively. Substitute the obtained aluminum foil surface crack value ZLc1, aluminum foil surface scar value ZBc1, and aluminum foil surface oxidation value ZYc1 from the front side of the aluminum foil into the formula. In the calculation, the front surface performance value ZZc of the aluminum foil is obtained; Using a vision camera, the surface crack value, surface scar value, and surface oxidation value of the aluminum foil on the reverse side are obtained and labeled as ZLc2, ZBc2, and ZYc2, respectively. Substitute the obtained aluminum foil surface crack value ZLc2, aluminum foil surface scar value ZBc2, and aluminum foil surface oxidation value ZYc2 from the reverse side into the formula. In the calculation, the reverse side performance value ZFc of the aluminum foil is obtained; where a1, a2, and a3 are all proportionality coefficients, with a1 being 0.32, a2 ​​being 0.51, and a3 being 0.17. Substitute the obtained front-side performance value ZZc and back-side performance value ZFc of the aluminum foil into the formula. In the calculation, the rough rolling performance value ZBC of aluminum foil was obtained; where a4 is 0.84 and a5 is 0.16. Thus, the aluminum foil performance value ZBC1 before rough rolling and the aluminum foil performance value ZBC2 after rough rolling are obtained; Step 2: Based on the aluminum foil performance data, analyze and judge whether the rough rolling process meets the rough rolling process requirements, and generate a rough rolling quality signal accordingly; Among them, the roughing quality signals include roughing qualified signals and roughing unqualified signals; In some embodiments, the performance value ZBC2 of the aluminum foil after rough rolling is obtained, and the performance value ZBC2 of the aluminum foil after rough rolling is compared with the performance threshold of the aluminum foil after rough rolling. If the performance value ZBC2 of the aluminum foil after rough rolling is less than the performance threshold of the aluminum foil after rough rolling, a rough rolling qualified signal is generated. If the performance value ZBC2 of the aluminum foil after rough rolling is greater than or equal to the performance threshold of the aluminum foil after rough rolling, a rough rolling failure signal is generated. When a roughing failure signal is received, an aluminum foil rolling pause signal is generated, and the subsequent intermediate and finishing rolling processes of the aluminum foil will not be completed. Step 3: Based on the roughing quality signal, analyze the roughing equipment to obtain the roughing equipment signal; Among them, the roughing mill equipment signals include normal roughing mill equipment signals and abnormal roughing mill equipment signals; In some embodiments, when a roughing failure signal is received, real-time roughing parameters are acquired and collected. The real-time roughing parameters include actual temperature parameters and actual pressure parameters. The actual temperature parameter refers to the real-time temperature during the aluminum foil rolling process; the actual pressure parameter refers to the real-time pressure during the aluminum foil rolling process. The real-time roughing parameters are compared with the previously recorded roughing parameters stored in the database. These previously recorded roughing parameters refer to the conditions under which qualified aluminum foil products are obtained. The roughing parameters for unqualified aluminum foil products will be automatically deleted and not saved. The previously recorded roughing parameters stored in the database are marked as past parameters, which include past temperature parameters and past pressure parameters. The past temperature parameters refer to the temperature parameters previously recorded during the roughing process, and the past pressure parameters refer to the pressure parameters previously recorded during the roughing process. The specific comparison process includes: if the past parameters contain the real-time roughing parameters, it is determined that the real-time roughing parameters are stored in the previously recorded roughing parameters, and a parameter qualified signal is generated; if the past parameters do not contain the real-time roughing parameters, it is determined that the real-time roughing parameters are not stored in the previously recorded roughing parameters, and a parameter unqualified signal is generated. When a parameter non-compliance signal is received, the actual temperature parameter and actual pressure parameter belonging to the parameter non-compliance signal are extracted and marked as non-compliance actual temperature parameter and non-compliance actual pressure parameter, and the real-time parameters corresponding to the non-compliance actual temperature parameter and non-compliance actual pressure parameter are obtained. The real-time parameters refer to the real-time nodes in the aluminum foil rolling process. A virtual Cartesian coordinate system is plotted, with real-time parameters designated as X-axis values ​​and non-compliant actual temperature parameters designated as Y-axis values. The lowest Y-axis value is selected and its corresponding actual temperature data is labeled as the low-temperature value, while the highest Y-axis value is selected and its corresponding actual temperature data is labeled as the high-temperature value. The distance between the low-temperature and high-temperature values ​​is calculated and marked as the temperature distance value ZWC. A virtual Cartesian coordinate system is plotted, with real-time parameters designated as X-axis values ​​and non-compliant actual pressure parameters designated as Y-axis values. The lowest Y-axis value is selected and its corresponding actual pressure data is labeled as low-pressure value, while the highest Y-axis value is selected and its corresponding actual pressure data is labeled as high-pressure value. The distance between the low-pressure and high-pressure values ​​is calculated and marked as the pressure distance value ZYC. Substitute the obtained temperature distance value ZWC and pressure distance value ZYC into the formula. In the calculation, the evaluation value ZPC of the roughing mill is obtained; where a6 and a7 are both proportionality coefficients, a6 is 1.05 and a7 is 1.23. The obtained evaluation value ZPC of the roughing mill is compared with the evaluation threshold of the roughing mill. If the evaluation value ZPC of the roughing mill is less than the evaluation threshold of the roughing mill, a normal signal for the roughing mill is generated. If the evaluation value ZPC of the roughing mill is greater than or equal to the evaluation threshold of the roughing mill, an abnormal signal for the roughing mill is generated. The technical solution of this invention involves acquiring aluminum foil performance data during rough rolling, analyzing the aluminum foil performance data to determine whether it meets the rough rolling process requirements, and generating a rough rolling quality signal accordingly. Based on the rough rolling quality signal, the rough rolling equipment is analyzed to obtain a rough rolling equipment signal. When a normal signal is obtained for the rough rolling equipment, it indicates that there is no fault in the rough rolling equipment, and personnel need to be arranged to check the rolling oil in the rough rolling process. An abnormal signal for the rough rolling equipment indicates that there is a fault in the rough rolling equipment, and personnel need to be arranged to check the rough rolling equipment. Example 2
