Health Prediction of Integrated Die-Casting Machine Driven by Digital Twin and CNN-LSTM
Bibliographic record
Abstract
In order to solve the problem that the health status of the integrated die-casting machine is difficult to control during the operation and maintenance process, a health state prediction method of the integrated die-casting machine driven by the fusion of digital twin and CNN-LSTM was proposed. Firstly, based on the digital twin theory, a digital twin model of condition monitoring of the integrated die-casting machine was constructed to realize the real-time mapping of the real-time status and performance parameters of the integrated die-casting machine and the digital twin. Secondly, based on the CNN-LSTM machine learning algorithm, the life characteristics data of key components of the integrated die-casting machine were mined, and the life prediction model of the key components of the integrated die-casting machine was established, so as to realize the online prediction of the remaining effective life driven by the real-time monitoring data of the twin model. Finally, the effectiveness of the proposed method is verified by constructing an integrated status monitoring and health prediction system for the integrated die-casting machine, which provides a new idea for the intelligent maintenance and management of the integrated die-casting machine.

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.
