ABSTRACT An application is presented for online model-based fault detection
and isolation (FDI) in a multitank fluid system. The tank system is
equipped with a distributed measurement and control system that
implements components of the IEEE standard for smart transducers, IEEE
1451. This standard includes an information model that provides
programming constructs to support high level application functionality
on a distributed network of smart transducers. The model-based FDI
methodology in this work has several aspects that may be realized on
such a distributed network. In the current work, the FDI application
operates on a workstation that appears on the network as another
(virtual) transducer node. The concurrent tasks in the application may
be associated with actual transducer nodes. It represents a first effort
toward constructing capabilities for distributed FDI in complex dynamic

    ABSTRACT: In this paper, we present a scheme of rough-set-based minimal set of feature selection and classification of power quality disturbances that can be implemented in a general-purpose microcontroller for embedded applications. The developed scheme can efficiently sense the power quality disturbances by the features extracted from the cross-correlogram of power quality disturbance waveforms. In this paper, a stand-alone module, employing microcontroller-based embedded system, is devised for efficiently sensing power quality disturbances in real time for in situ applications. The stand-alone module is developed on a PIC24F series microcontroller. Results show that the accuracy of the proposed scheme is comparable to that obtained in offline analysis using a computer. The method stated here is generic in nature and can be implemented for other microcontroller-based applications for topologically similar problems.

    ABSTRACT: This paper considers the development of a Petri-net-based modelling tool as a mechanism for process and system monitoring. The use of Petri-nets, which has previously been largely based in the areas of systems modelling and simulation, is shown here to have great potential for deployment as a process monitoring and management application. Interfacing with real-world processes has been achieved in part by introducing a specific set of extensions to the original Petri-net concept. This work has resulted in the engineering of a tool that can be embedded within the process using a microcontroller platform. The potential for such systems to provide low cost, yet powerful process management tools, is becoming increasingly evident, particularly given the ever-improving capabilities of microcontrollers.

    ABSTRACT: The IEEE 1451 smart transducer interface standards was created to provide the common interface and enabling technology for the connectivity of transducers to realtime distributed measurement and control system. The standardized TEDS specified by IEEE 1451.2 allow the self-description of sensors and the interfaces provide a standardized mechanism to facilitate the 'plug and play' of sensors to networks. A smart high-performance quartz tuning fork temperature sensor (QTFS) with a prototype IEEE 1451 Internet interface was implemented by microprocessor PIC16F877. A software environment has been developed to realize the full STIM functionality, this STIM implementation is interfaced to a NCAP to demonstrate a remote temperature measurement and control application, operating over the World-Wide-Web. Experiment and results of the demonstration project have proved that the smart transducers possess high-performance and enable Internet access of networks
