System and method for detecting welding based on edge computing

A method for detecting welding based on edge computing, the method comprising:

• obtaining welding information from at least one welding machine using at least one edge server,
• preprocessing the welding information to generate processed data,
• inputting the processed data to a trained algorithm to obtain a detecting result, and
• determining welding quality of the welding machine according to the detecting result;
• wherein the welding information comprises welding detecting information, the welding detecting information comprises at least one of detected information of a bath of the welding piece or neighborhood of the bath of the welding piece obtained during welding and position information of welding spots of the welding piece, the processed data comprises first processed data, the first processed data is generated by preprocessing the welding detecting information, the trained algorithm comprises a determining algorithm, the determining algorithm is trained by a plurality of training datasets based on historic welding detected information;
• preprocessing the welding detecting information using the at least one edge server to generate the first processed data, by performing at least one of average filtering, median filtering, and Gaussian smoothing;
• inputting the first processed data to the determining algorithm to generate first determining information;
• inputting the first processed data again to the determining algorithm to generate second determining information;
• based on the first determining information and the second determining information, determining a connected area of the first determining information and the second determining information;
• analyzing a principal component of the first determining information and the second determining information, to mark the connected area;
• and
• based on the marked connected area, adjusting the first determining information or the second determining information, to form third determining information;
• processing and storing the detecting result and the welding information uploaded by each edge server using a data server, generating display information, and visualizing the detecting result according to the display information.
