Description

Technical Field

[0001] The present invention relates to the field of intelligent manufacturing technology, and more specifically, to a factory equipment management system and method based on a digital twin platform. Background Art

[0002] Traditional manufacturing companies rely mainly on manual labor for equipment management. Information registration relies on notes, equipment status relies on manual observation, and equipment analysis relies on manual guesswork. The more "many, large, and complex" the equipment management, the more prominent the drawbacks of manual management. In the long run, there will be more and more abnormal equipment downtime problems, which will naturally affect production efficiency.

[0003] During the operation of factory equipment, the operation status of the equipment depends on manual regular inspections and troubleshooting, which takes a long time and cannot achieve real-time maintenance. Once a sudden failure occurs, the production can only be stopped for maintenance. Relying on traditional manual inspections, on-duty, and manual switch control, the operation and maintenance status of the operation and maintenance personnel after they realize it can no longer adapt to the current situation. On the one hand, on-site equipment maintenance is becoming more and more difficult, and the maintenance cost is increasing. On the other hand, users' maintenance requirements for equipment are also constantly increasing. Therefore, we propose a factory equipment management system based on a digital twin platform and its method to solve the above problems. Summary of the invention
