Diagnosis of a continuous dynamic system from distributed measurements

A diagnosis application has been built for a three-tank fluid system. The tank system is equiped with a distributed measurement and control system based on smart transducer nodes with embedded computing and networking capabilities that use the IEEE 1451.1 object model to provide high level sensing and actuation abstractions. The diagnosis system operates on-line on a workstation that-appears on the network as another transducer node. The diagnosis methodology has several aspects that allow distribution of the monitoring and diagnosis functionality on a network of embedded processors. The current application represents the initial phase in building a truly distributed monitoring and diagnosis application.
