Abstract

The invention discloses a method and system for fault tracing of a manufacturing system based on a digital twin model, comprising the following steps: step A, building a digital twin fault trace mathematical model on a simulation platform; step B, building a manufacturing system on a simulation platform A visual simulation model of the digital twin of the manufacturing system; Step C, establish a digital twin model of the manufacturing system; Step D, search all fault propagation paths in the information processing model based on the multi-color set through a breadth-first root search algorithm, Find out the root cause of the failure. The root cause of the fault can be found better and faster, which helps to improve the diagnosability, and assists technicians to propose targeted reliability improvement measures.

Description

technical field [0001] The invention relates to the field of system fault traceability, in particular to a manufacturing system fault traceability method and system based on a digital twin model. Background technique [0002] Diagnosability and maintainability of manufacturing systems are as important as reliability. Failure resilience is critical to reducing production downtime. Manufacturing equipment reliability growth is a process of constant testing, constant redesign, and constant adjustment. It is also a systems engineering, since machines are usually highly coupled systems composed of mechanical, electronic, electrical and hydraulic components and components. In many cases, the costs involved in improving reliability increase substantially as system reliability levels approach the maximum achievable reliability. At some point, improving diagnosability and maintainability is more economical than improving system reliability. [0003] A few minutes of stoppage in t...
