A standardized smart transducer interface

Abstract

In December 2000 the Object Management Group (OMG) called for a proposal of a smart transducer interface. In response a new standard has been proposed that comprises a time-triggered transport service within the distributed smart transducer subsystem and a well-defined interface to a CORBA environment. This smart transducer standard has been adopted by the OMG in January 2002. The smart transducer interface and the time-triggered transport service have been implemented in the time-triggered fieldbus protocol TTP/A. This paper examines the strengths and weaknesses of the smart transducer interface and presents two case studies. The first case study describes a demonstrator with a robot arm that is instrumented by smart transducers and a TTP/A fieldbus. The second case study is an autonomous mobile robot instrumented by a TTP/A cluster that orientates itself via a set of heterogenous sensors and decides, based on this sensor data, which way to go.

An Event-Triggered Smart Sensor Network Architecture

“…A smart transducer interface must be conform to one of the world-wide standard. Such a standard for a realtime communication network has been long sought, but efforts to find one agreed standard have been hampered by vendors, which were reluctant to support such a single common standard in fear of losing some of their competitive advantages [6].…”

“…In response, a new standard has been proposed that comprises a time-triggered transport service within the distributed smart transducer network and a well-defined interface to a CORBA environment with enables maintenance activities [1], [6]. This smart transducer standard has been adopted by the OMG in January 2002 [3].…”

“…The transfer of information between a smart transducer and its client is achieved by sharing information contained in an internal interface file system (IFS), which is encapsulated in each smart transducer. Thus, the IFS is the source and sink for all communication activities [6].…”
