Multi-network access to IEEE P1451 smart sensor information using World Wide Web Technology
Richard D. Schneeman, Kang Lee · 1999
NIST and a consortium of companies are organizing a public demonstration of the features of IEEE P1451, a Draft Standard for a Smart Transducer Interface for Sensors and Actuators.The demonstration is set in a multivendor transducer and control network environment during the May '97 Sensors Expo in Boston.This paper presents the design of the demonstration system which uses a server architecture based on the industry standard UDP/IP protocol and the gateway software module that bridges the UDP Ethernet-based network and the specific control network technology.The definitions of a common set of ASCII-based message protocol units are defined to allows cross network and transducer device communication.Combining these approaches using Internet-based technologies such as World Wide Web browser software, Java, HTML Web pages, and the Internet Protocol suite, the demonstration shows the functionality and interoperable capability of the proposed interface for connecting sensors and actuators to control networks.It also shows that the implementation of the interface based on the draft specification is realizable.
