Research on Real Time Condition Monitoring and Fault Warning System for Construction Machinery under Multi Source Heterogeneous Data Fusion
Bibliographic record
Abstract
This study focuses on the application of multi-source heterogeneous data fusion in real-time status monitoring and fault warning systems for construction machinery, and conducts in-depth analysis of the latest developments in status monitoring and fault diagnosis technology for construction machinery. A monitoring scheme combining data-driven and machine learning is proposed to address the problem of frequent failures in construction machinery in complex operating environments. This solution utilizes efficient data collection and processing from multiple sensors, and applies deep learning models to achieve fault prediction and diagnosis. It can effectively identify potential faults, prevent risks in advance, and improve equipment reliability and operational safety. This article starts with the overall design architecture and core technologies, and provides a detailed introduction to the construction process of data preprocessing, feature extraction, and fault diagnosis models. It also explores the challenges of outdoor operating conditions in monitoring the status of construction machinery. Research has shown that the application of automated state monitoring and early warning systems can significantly reduce the incidence of failures, minimize economic losses, and improve operational efficiency and safety.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
