Title:
FAULT DETECTION IN ROTOR DRIVEN EQUIPMENT USING ROTATIONAL INVARIANT TRANSFORM OF SUB-SAMPLED 3-AXIS VIBRATIONAL DATA
Document Type and Number:
WIPO Patent Application WO/2016/137849
Kind Code:
A4
Abstract:
A method and system of detecting faults in rotor driven equipment includes generating data from one or more vibration sensors communicatively coupled to the rotor driven equipment. The data from the one or more machine wearable sensors is collected onto a mobile data collector. The data is sampled at random to estimate a maximum value. Further, a sampling error may be controlled under a predefined value. The data may be analyzed through a combination of Cartesian to Spherical transformation, statistics of the entity extraction (such as variance of azimuthal angle), big data analytics engine and a machine learning engine. A fault is displayed on a user interface associated with the rotor driven equipment.
