Real-time leak detection of long-distance oil and gas pipelines based on distributed optical fiber temperature measurement technology based on Raman scattering. The system can comprehensively utilize the analysis of real-time temperature, temperature rise and fall rate, temperature rise and fall trend, etc. to achieve continuous monitoring. It can accurately display the temperature status of any position of the whole pipeline at any time, and alarm and accurately locate when the pipeline leaks.
System functions
1. Detection of leakage of oil pipelines: Through the implementation of monitoring the temperature around the optical cable, the purpose of leak detection of oil pipelines is achieved;
2. Abnormal alarm: When the detection temperature exceeds the setting range, the alarm information is prompted and the operation suggestion is given;
3. Differential temperature alarm: The alarm parameter supports manual setting, output relay alarm signal and alarm positioning information, and realize differential temperature alarm;
4. Alarm partition setting: The system can program the alarm area length and alarm point as a whole, and can be flexibly adjusted according to the site conditions;
5. Data analysis: historical data storage, query and analysis;
6. Remote access: The system can access industrial Ethernet and transmit data to all levels of management to achieve remote access.
