Proactive Threshold-based Early Warning

1) Temperature Parameters and Alarm Thresholds

Configure alarm thresholds in the monitoring software in line with requisitos e padrões de segurança. Por exemplo, 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 taxa de aumento exceeds a set value (por exemplo, 5 °C/min), um Level-2 alarm is triggered, enabling proactive intervention—shifting from after-the-fact handling para before-the-fact prevention.

2) Preciso, High-Accuracy Spatial Localization

Em monitoramento de vazamento de dutos, the system rapidly determines the exact location of the leak, saving troubleshooting time for maintenance teams and reducing losses caused by leakage.

3) Em tempo real, Full-Coverage Monitoring and Visualization

The system runs 7×24 com 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. UM 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.
