Monitoring Distributed Parameter Systems Based on Expert Systems and Sensor Networks

The paper presents an application of expert systems for monitoring phenomenon seen as distributed parameter systems. The information from these systems may be obtained using sensor networks and estimation techniques. The problem is formulated in the frame of general knowledge about distributed parameter systems, with application at the heat transfer. A knowledge base may be developed using human expertise on such distributed parameter system, related to the way how the phenomenon is happenning in time and space. The expert system may be implemented in real time using virtual instrumentation. The resulted virtual instrument can be placed in the real distributed parameter system, as a tool for fault detection and diagnosis.
