Digitization of production line equipment of rail transit vehicles based on index and model

In the process of digital transformation of rail transit vehicles, the digitalization of production line equipment is an important content. Starting from the whole life cycle business of production line equipment, this paper improves the existing production line equipment index system, proposes the production line equipment data acquisition model, describes the equipment portrait, proposes the comprehensive evaluation system based on the equipment index model, and further explores the digital twin architecture of production line equipment based on the integration of multiple models. Improve the digital level of rail transit vehicle manufacturing production line equipment.
