摘要： A method for extracting a feature of a vibration signal, and a device analysis method and apparatus. The method includes: processing the vibration signal to obtain a derivative signal from the vibration signal (S420), the derivative signal being used for characterizing one or more characteristics of the vibration signal; extracting a feature of the vibration signal and the derivative signal respectively to obtain a first feature extraction result of the vibration signal and a second feature extraction result of the derivative signal (S430); and taking the first feature extraction result and the second feature extraction result as final feature extraction results of the vibration signal. The finally obtained feature extraction results may be used to analyze the vibration signal from different perspectives, thereby improving the universality of the feature extraction results.

摘要： The invention relates to a method (PRC) for monitoring the operation of a machine (MCH), in particular of a motor (ENG) or electrically driven motor (EEG). To improve the monitoring, the method proposes a method of this type comprising the following steps: c) training phase (TPH): i. providing training data (TDT) comprising state variables (PHC) of multiple operating points (OPP) of the machine (MCH), ii. recognizing and combining operating points (OPP) in the training data (TDT) through clustering (CLS) to form operating-point clusters (OCL), i. training a classifier (CLF), which assigns operating points (OPP) to the recognized operating-point clusters (OCL), iv. training an anomaly recognition model (ARM) for recognizing operating anomalies, d) application phase: i. recording operating data (OPD) comprising state variables (PHC) of operating points (OPP) of the machine (MCH) in an operating state, ii. assigning the operating data (OPD) to the operating-point clusters (OCL) using the classifier (CLF), recognizing operating anomalies using the anomaly recognition model (ARM).

摘要： A real-time computer system for automated acoustic anomaly detection in a programmable logic controller (PLC) is disclosed, the computer system being deployed onto a backplane of the PLC. The computer system includes at least one processor with a real-time operating system and a memory having algorithmic modules stored thereon executable by the processor. The modules include a digital signal processing module configured to apply a windowing function to the sound signal data captured by a sensor, the sound signal data representative of sound emitted by an energized work product under quality inspection. The modules further include a feature extraction component configured to extract acoustic features from each sound window, and an anomaly detector module configured to operate a machine learning-based model to execute acoustic anomaly detection according to results of a classification operation on the acoustic features.

摘要： Embodiments of this application provide a method and system for measuring motor damping. In the method for measuring motor damping, a driving signal is generated to drive a to-be-tested motor to operate, and at a cut-off moment of the driving signal, the to-be-tested motor enters a free damping state and a turn-off signal is generated at this moment to cut off a test circuit of the to-be-tested motor. In this way, an acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state can be acquired, and damping of the to-be-tested motor is obtained by using the acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state, thereby realizing the measurement of the damping of the to-be-tested motor.

摘要： A computer-implemented method for simultaneous estimation of water encroachment and bound fluid in the absence of NMR in carbonate reservoirs is described. The bulk volume of water (BVW) is computed by multiplying porosity and water saturation. The Buckles number is computed for each petrophysical rock type (PRT). Water saturation in unseen wells is estimated using the Buckles number, porosity (from porosity logs) and PRT. Water saturation is evaluated to estimate water encroachment. Additionally, bound fluid for the new wells is estimated in the absence of NMR data.
