Digital twin virtual commissioning technology platform is a new equipment solution suitable for the research and development of automation equipment. With the help of this software platform, 3D modeling, simulation and virtual commissioning can be performed on concepts that include multiple physical fields and automation-related behaviors that are usually present in automation equipment. The movement and working state of automation equipment are simulated through digital models, and mechanical and electrical linkage virtual commissioning is achieved. Through the virtual-real connection of twins, continuous iteration of data, and continuous optimization of models, the optimal automation equipment solution is obtained.
