Abstract

PURPOSE:To treat a fault effectively while relieving an operator from the load of investigating the cause, by obtaining information effective to the investigation on the cause of the fault from the change of data before the fault is detected in the occurrence of the fault. CONSTITUTION:Data of each plant up to the detection of a fault by a fault detector 3 is stored previously as a fault cause tree 10, and a data change table 9 containing the tree 10 and the change of data before the fault is detected, and a secular value table 8 recording data in the detection of the fault are used to analyze the cause of the fault. Then, a fault cause deciding device 6 analyzes the cause of the fault from the tree 10 and the result of it is displayed 7. Here, the tree is displayed to display the change and path of the plant data understandably. Since the time when the data changed is also stored in the table 9, it is displayed simultaneously. Consequently, a plant fault is treated rapidly and adequately.
