AI Technical Summary

Technical Problem

Existing multi-sensor monitoring solutions suffer from redundant data processing and invalid calculations, resulting in long anomaly location times and a high risk of misjudgment, failing to meet the high reliability requirements of industrial motors.

Method used

A multi-mode switching monitoring system based on level position analysis is adopted. Through damper adjustment and multi-mode monitoring and progressive analysis, combined with torque and speed sensors, piezoelectric acceleration sensors, current sensors, voltage sensors and temperature sensors, data is collected in all dimensions. By using the chain analysis strategy of the analysis module and the benchmark parameter comparison of the simulation module, the anomaly type can be accurately identified and verified.

Benefits of technology

It enables the adjustment and amplification of abnormal features through damper adjustment without interrupting production, providing an operable physical intervention basis, improving the accuracy of anomaly identification and overall operational efficiency, reducing redundant analysis steps, and possessing self-learning capabilities to expand the identification range.
