RESIDUAL SERVICE LIFE DIAGNOSING SYSTEM FOR POWER GENERATION PLANT EQUIPMENT

摘要

PURPOSE:To improve the predicting accuracy of the residual service life of equipment and to select the equipment targeted to be inspected with high reliability by using a system utilizing reliability analysis assuming Weibull distribution in the prediction of the residual service life of the equipment. CONSTITUTION:Software to diagnose the residual service life of the equipment is stored in an expert system 6. The system 6 is comprised of a knowledge base 1 to perform expression so as to perform the inference processing of knowledge with respect to a preventive maintenance job obtained from an expert of experience in the past and to store it, a knowledge acquring support mechanism 2 to perform the input, the change, and the debugging of the knowledge, an inference mechanism 3 to execute inference and control based on the knowledge base 1, a user interface 4 to easily perform the input and the maintenance of the knowledge obtained from the expert or the response of a user, and a system interface 5 to fetch data from the outside. A data base system 7 manages the system 6 and plant data. and the input/output functions of a keyboard and a display, etc., can be performed with a terminal system 8.
