ANOMALY SENSING AND DIAGNOSIS METHOD, ANOMALY SENSING AND DIAGNOSIS SYSTEM, ANOMALY SENSING AND DIAGNOSIS PROGRAM, AND ENTERPRISE ASSET MANAGEMENT AND INFRASTRUCTURE ASSET MANAGEMENT SYSTEM

摘要

To provide an anomaly sensing and diagnosis method and system with which it is possible to sense anomalies in manufacturing plants and other infrastructure at an early stage and with high sensitivity: mutual associations are formed, using keyword frequencies (context), in maintenance history information which comprises prior case histories such as task histories or replacement component information; sensed anomalies and the linked maintenance history information are linked based on anomaly sensing which takes output signals of multidimensional sensors installed in the infrastructure as the object of said anomaly sensing; and thereby, when a symptom is sensed, the relationship between the symptom and a countermeasure, such as replacing a component, or adjustment or reactivation, is conferred, the diagnosis and steps to take with respect to the anomaly which has occurred are clarified, and task instructions are presented.
