METHOD AND SYSTEM FOR DIAGNOSING HYDRAULIC DRIVE FUNCTIONAL INSTALLATIONS, USING INFRARED THERMOGRAPHY

The invention relates to a method and to a system for diagnosing hydraulic drive installations. The claimed system comprises a thermographic camera (CT) by means of which two scannings of the components (1...5) of a hydraulic drive installation (IAH) are peformed in two different moments, namely during the tests of putting the installation (IAH) into operation, where a database with five sets of standard thermograms (T...T) are obtained, and during the periodical revision tests of the installation (IAH) where another database with five sets of revision thermograms (T...T) are obtained, a storage module (6) for storing the two databases, a programmable automaton (7) which compares the two thermograms to one another, calculates the overheating of the revised installation, and, depending on that, it allocates them in component state files.
