LIVE Digital Twin: Developing a Sensor Network to Monitor the Health of Belt Conveyor System
Bibliographic record
Abstract
Industry 4.0 requires developing smart systems to maximize the uptime of machines and components. Digital Twins can be defined as a real time exchange of the information between a physical asset and a virtual portrayal in a bidirectional manner. This relationship is best established with a sensor network. LIVE Digital Twin presents a methodology to design model-based Digital Twins for asset management through sensors. This methodology is increasingly useful when the fault history of an asset is not readily available. The LIVE Digital Twin methodology consists of four principle phases, Learn, Identify, Verify, Extend. The goal of this research is to review the application of the LIVE Digital Twin methodology on a case study of a Belt Conveyor System found in the mining industry. Belt Conveyor Systems and their rollers are critical in material transportation and are susceptible to various faulty cases. Using a multi fidelity approach, a case study demonstrates the first two phases of LIVE Digital Twin and identifying the sensor locations. The study concludes with the successful location of 2 sensors on a subassembly of a Belt Conveyor System frame.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
