The captured images are uploaded to the coil number analysis host, and the AI identifies the circulation one-dimensional label of the incoming steel coil. Through this circulation one-dimensional label, the automatic tracking of the steel coil on the production line is realized, replacing the manual identification method and eliminating various errors.

[0012] S2. The analysis host transmits the coil number recognition result to the process automation system, displays the coil information and packaging requirements of each saddle, and the automation system of the packaging production line can then track the steel coil on the production line. S3. The production execution system realizes automatic feeding, output, and packaging according to the coil information and packaging requirements. S31. Using big data modeling, a matching relationship between the coil information and packaging requirements is formed and stored in the database. S32. Compare the recognition result of the analysis host with the data in the database to obtain the matching relationship. S33. When the data comparison is matched, the corresponding relationship between the steel coil and the packaging is output; when the data comparison is not matched, the matching relationship is selected manually, and the corresponding relationship between the steel coil and the packaging is output. S34. The new matching relationship formed according to the manual selection is stored in the database. S35. The output corresponding relationship between the steel coil and the packaging is transmitted to the screen for prompting, and a production execution system command is generated for the feeding, output, and packaging operation processes.

[0013] S4. After the feeding, output, and packaging are completed, it triggers the warehouse area system to identify the steel coil and print the finished product two-dimensional label. S5. Compare the finished product label and the circulation label after the steel coil packaging production line. When the steel coil passes through a saddle of the walking beam on the packaging production line, it triggers the dual high-definition cameras at the exit end to capture before warehousing. The captured images are uploaded to the coil number analysis host. The analysis host compares the recognized circulation one-dimensional label and the coil number of the finished product two-dimensional label, and analyzes the content in the label through a dedicated intelligent software to realize the AI comparison and analysis of the label information. When they are inconsistent, an audible and visual alarm is given, thus avoiding mislabeling and fundamentally eliminating the problem of mixed numbers, solving the obvious quality objections of mixed numbers and information inconsistency that have plagued the production line for many years, and improving the technical means of quality control. Furthermore, the comparison content of the labels includes: comparing the card numbers of the finished product label and the circulation label; comparing the information displayed on the finished product label with the system information; and making a secondary comparison between the weight and width displayed on the finished product label and the actual measurement data of the packaging production line.
