METHOD FOR LOCATING MULTIPLE UNCONTROLLED FAILURES OF TECHNICAL SYSTEMS

摘要

The proposed method and device enable to improve efficiency, depth and reliability of diagnosing technical condition of highly complex objects. The said technical effect is achieved due to the fact that, according to the method, signals are received from a diagnosed object (DO), these signals are transformed into a technical condition initial estimate vector for the DO elements. Then, technical condition estimates for the OD elements are specified through a cyclical process and by using a reverse logical model and a direct logical model. A technical condition vector estimate is formed after the cyclical process is completed, and its variable components are used for deciding on technical condition of the diagnosed object elements. The device comprises an interface unit which inputs serve for connecting to the DO data outputs, a measuring unit, an initial estimate forming unit, a switching unit, a reverse triplex logical model and a direct triplex logical model, a result interpretation unit and a control unit.
