Zusammenfassung
Decentralised, modular production with the aim of individualised products leads to a more flexible production setup which, however, also influences the handling of faults and failures. Since faults occur rarely compared to nominal behavior of Cyber-Physical Production Modules (CPPM), it is difficult in common manufacturing environments and even harder in skill-based production to gain experience and knowledge about faults and the context they occur in. Hence, leveraging knowledge and data from multiple CPPM proves beneficial, facilitating the storage of acquired information regarding faults and their context in federated knowledge bases. However, although different approaches tackle the communication between distributed knowledge bases, the use for distributed knowledge-based fault detection and diagnosis in skill-based production environments remains mainly unseen. In this paper the focus lies on the development of a communication scheme that enables automated communication between fault detection and fault diagnosis components for a decentralised control setup to make distributed knowledge about faults accessible. This includes the definition of fault detection and fault diagnosis components and their offered services which encapsulate different forms of knowledge representations. For the communication between the components, a unified model is elaborated, and the required information is identified. An integration in a holonic manufacturing system of SmartFactoryKL is presented and an outlook for further research is given.
