Proactive Threshold-based Early Warning

1) Temperature Parameters and Alarm Thresholds

Configure alarm thresholds in the monitoring software in line with vereisten En veiligheidsnormen. Bijvoorbeeld, when temperature exceeds the upper limit of 80 °C, the system issues a Level-1 alarm automatically. If the temperature rises sharply in a short time and the stijgingspercentage exceeds a set value (bijv., 5 °C/min), A Level-2 alarm is triggered, enabling proactive intervention—shifting from after-the-fact handling naar before-the-fact prevention.

2) Nauwkeurig, High-Accuracy Spatial Localization

In pipeline leak monitoring, the system rapidly determines the exact location of the leak, saving troubleshooting time for maintenance teams and reducing losses caused by leakage.

3) Realtime, Full-Coverage Monitoring and Visualization

The system runs 7×24 met no blind spots across all areas covered by the installed sensing fiber. Whether during busy daytime production or at night with minimal staffing, it continuously safeguards plant assets. A visualized real-time dashboard presents monitoring data intuitively, allowing operations and maintenance personnel to view the plant’s status anytime, anywhere, with clear situational awareness.
