This product collects multi-source data from production equipment in real time, deeply integrating advanced digital signal processing, artificial intelligence algorithms, and an expert knowledge base to achieve round-the-clock monitoring of equipment operating conditions, intelligent fault analysis, and precise fault localization. Once an anomaly is detected, the system can rapidly diagnose the cause, automatically generate and push reasonable maintenance recommendations to maintenance personnel terminals, guiding on-site precision maintenance. The system enables a transition from "reactive maintenance" to "predictive maintenance," allowing early detection of potential faults, effectively avoiding unplanned downtime, extending equipment life, and providing intelligent assurance for the continuous and stable production of coal preparation plants.
