Method and system for real-time tracking of cold rolling weld joint based on digital twinning

The invention provides a method and a system for real-time tracking of a cold rolling weld joint based on digital twinning. The method comprises the following steps: building a cold rolling line overall model; setting strip steel parameters according to the cold rolling line overall model; inputting set strip steel parameters into the packaged built-in function to generate a strip steel model; acquiring a position change signal of a welding seam and a loop quantity change signal of a loop car; setting motion parameters; and according to the position change signal of the welding seam and the loop quantity change signal of the loop car, inputting set motion parameters into the strip steel model, calculating the real-time position of the welding seam, and moving according to the real-time position of the welding seam. According to the method, the strip steel modeling time of modeling personnel and the debugging time of developers are shortened. 本发明提供了一种基于数字孪生的冷轧焊缝实时跟踪的方法及系统，包括如下：搭建冷轧线整体模型；根据冷轧线整体模型设定带钢参数；将设定的带钢参
