JPS6459599A - Abnormal time plan supporting device for process plant - Google Patents

Abstract

PURPOSE:To diagnose an unknown abnormality cause and to make and synthesize a measure plan by searching and diagnosing an abnormality and further, making and synthesizing the measure plan based on a function hierarchy structure. CONSTITUTION:An inference mechanism 5, first, reads plant data and the knowledge to execute the abnormality diagnosis of the process plant and to make and synthesize the measure plan for the abnormality from a plant data base 3 and a knowledge base 4. The inference mechanism 5 executes the abnormality diagnosis in accordance with the knowledge to execute the abnormality diagnosis while the plant data are referred. Next, the inference mechanism 5 makes and synthesizes the measure plan for the abnormality in accordance with the knowledge to make and synthesize the measure plan for the abnormality based on the abnormality diagnosing result. The result of the inference due to the inference mechanism 5 is presented to an operator by a man machine interface 6. Thus, even the unknown abnormality cause and the abnormal pattern are diagnosed and the copying can be executed with the abnormality.
