Efficient structured data processing for web service enabled shop floor devices
2011 (English)In: 2011 IEEE International Symposium on Industrial Electronics (ISIE 2011): Gdansk, Poland, 27 - 30 June 2011, Piscataway, NJ: IEEE Communications Society, 2011, 1716-1721 p.Conference paper (Refereed)
State of the art factory automation systems are nowusing Service Oriented Architecture (SOA) in order to increaseﬂexibility and lower complexity of process monitoring andcontrol. However, the service technology has not yet penetratedinto the lower levels of plant-wide automation processes i.e.throughout shop ﬂoor devices such as programmable controllers,embedded sensors and actuators. Different techniques to adaptthe web service technology to the speciﬁc requirements of embedded systems domain are intensively investigated by researchersand yet real-time properties, limited resources and wirelesslinks are still posing immense challenges. The most promisingsolutions proposed are based on a newly emerging structureddata format - Efﬁcient XML Interchange (EXI). It is designedto compensate for the inefﬁciency of widely used throughoutservice implementations XML format. This paper investigates thedesign of EXI processor targeted at highly resource constrainedembedded devices found at the shop ﬂoor level. The EXIprocessor is proposed as an alternative to the XML parsersand serializers currently used in web service implementations.Among the results presented are a novel low level processorinterface and measurements quantifying the gained efﬁciencycompared to traditional XML-like interfaces. Reference opensource implementation equipped with the new interface is alsoprovided.
