EXSENSEL - A Rule-Based Approach to Selection. of Sensors for Process Variables

摘要

A novel expert-system-based method for selection of sensors for process variables is presented. EXSENSEL (expert system based sensor selection) deals with 12 process vari-ables and currently has 94 rules in its knowledge base. Despite its large knowledge base, users have to answer a set of only a few questions regarding a particular process variable, which is selected from a menu of 12 variables. A general description of the chosen process variable can be viewed before invoking the rules. Once a sensor has been selected, a brief write up on that particular sensor is also available on user's request. EXSENSEL is the successor to TRANSELEX, which is a single expert system for selection of transducers in the area of temperature, pressure, and flow measurement.
