A pragmatic architecture for ad-hoc sensing and servicing of industrial machinery

摘要

Sensing and servicing industrial machinery using Internet of Things technologies is both important and challenging. In the paper we consider the practical aspects related to the use of wireless sensor nodes as well as RFID for ad-hoc sensing and servicing at an industrial site. An appropriate basic architecture is considered based on web services and DPWS. The architecture, design and prototype implementation are presented and discussed. They take into consideration the needs from the service application, the heterogeneity of devices used and the future extendibility. We show how efficient sensor technology can be combined with standardized web services using a lightweight modular gateway architecture based on message transformation.
