The system designated as 4934 is an integrated solution specifically engineered for the thermal control and integrity monitoring of buried and overhead heat distribution pipelines.

Intelligent Temperature Control Strategy

• Fuzzy-PID Anti-Overshoot Control: Addresses the characteristics of heating networks (large capacity, long lag, non-linear). The self-tuning algorithm dynamically adjusts the proportional, integral, and derivative constants to maintain stable supply/return water temperatures, significantly reducing hydraulic imbalance.

Advanced Hybrid Leak Detection

• Distributed Optical Fiber (DTS): Monitors temperature fields along the pipeline in real-time. A sudden temperature rise at the insulation layer indicates a hot water leak, which can be located with high precision (meter-level).
• Infrared Thermal Imaging: Calculates relative leakage by analyzing the cumulative temperature offset between adjacent days on the pipeline surface, filtering out false positives caused by environmental temperature fluctuations.

System Architecture & Applications

• The system transmits data via an IoT gateway or SCADA interface to a centralized control platform, enabling 24/7 unattended operation. It is widely applicable in municipal central heating, industrial steam pipelines, and chemical fluid thermal transfer networks.
