How to monitor temperature of distributed fiber optic heating pipeline leakage

Fiber optic temperature sensor, Intelligent monitoring system, Distributed fiber optic manufacturer in China

The heating pipeline network of power generation enterprises serves as a centralized heating source to deliver and distribute thermal energy pipeline media with different parameter requirements (such as pressure, temperature, flow rate, etc.) to users. Its structure often adopts trench, direct burial or overhead laying methods, and there are practical problems such as long line distance, complex branch lines, scattered layout, limited monitoring, and poor positioning accuracy. Specifically, it can be attributed to the difficulty in locking the location of the temperature drop source; Difficulty in checking internal leakage of pipeline valves; Lack of monitoring of pipeline insulation effect.

Distributed fiber optic temperature sensing technology has been applied in the heating pipeline network system of power generation enterprises, and a monitoring network that can meet the requirements of long-distance, multi branch, high-precision, and real-time performance of the system has been designed and implemented.
The heating network monitoring system using distributed fiber optic temperature sensing technology embodies the design concept of distributed centralized control. With its own performance advantages, it can stably, efficiently, and continuously meet the monitoring needs of the system. By adopting a new installation process of internal and external insulation material laying and valve winding laying, monitoring and degradation analysis of pipeline valve leakage and insulation failure have been achieved.

1. Real time monitoring of the temperature at various points of the monitored object, which can be used to measure both lines and points.
2. Fiber optic cables are inherently safe, flame resistant, explosion-proof, and corrosion-resistant.
3. The monitor intuitively displays the specific location and name of each tested part. Perform real-time continuous temperature monitoring.
4. The system can intelligently analyze the fault trends of each monitored area and monitoring point, and accurately locate them.
5. The system has a LAN interface and can be connected to the enterprise LAN system or other network systems to achieve information sharing.
6. The system has a self diagnostic function that can instantly determine optical fibers and cables.
