In maintenance, the 'planned maintenance' mode is also taken as the main mode, the problems of insufficient maintenance mechanism basis, unscientific maintenance period, poor data utilization, non-visual data and fault feedback, low maintenance effect and the like exist, and the operation and maintenance cost is higher and higher in the full life cycle cost, so that a more efficient, more economical and more scientific operation and maintenance mode is sought to become a common target of a clean room.
Digital twinning is a model of digital replication of real physical entities, processes and systems. The digital twin model acquires and analyzes the real-time information of the physical model through multiple means such as actual measurement of a sensing device, model simulation, intelligent algorithm calculation and the like, and presents various elements in the physical model and real-time dynamic running conditions in the whole life cycle, so that the functions of simulating, monitoring operation and maintenance, process and system optimization, event prediction and the like of the system are realized. The application of the digital twin technology in the aspect of intelligent operation and maintenance of the clean room promotes the transformation of the traditional planning operation and maintenance mode of the clean room into a digitalized, networked and intelligent operation and maintenance mode.
