An intelligent fault recognizer for rotating machinery via remote characteristic vibration signal detection
Bibliographic record
Abstract
Monitoring industrial machine health in real-time is not only highly demanded but also significantly complicated and difficult. Possible reasons for this include: (a) Access to the machines on site is sometimes impracticable; and (b) The environment in which they operate is usually not human-friendly due to pollution, noise, hazardous wastes, etc. Despite the theoretically sound findings on developing intelligent solutions for machine condition based monitoring, there are few commercial tools in the market that can readily be used. This paper reports on the development of an intelligent fault recognition and monitoring system (Melvin I), which detects and diagnoses rotating machine conditions according to changes in fault frequency indicators. The signals and data are remotely collected from designated sections of machines via data acquisition cards. They are processed by a signal processor in order to extract characteristic vibration signals of ten key performance indicators (KPIs). A 3-layer neural network is designed to recognize and classify faults based on the set of KPIs. The system implemented in our laboratory and applied in the field can also incorporate new experiences into the knowledge base without overwriting previous training. Preliminary results have demonstrated that Melvin I is a smart tool for both system vibration analysts and industrial machine operators.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
