Utilizing a distributed fiber optic temperature measurement system to monitor pipelines in real-time 24/7, comprehensively grasping the temperature signal changes of the pipeline. In case of liquid or gas leakage in the pipeline, the system can generate an alarm in a timely manner and accurately locate the accident location.
The use of fiber optic distributed temperature monitoring technology has been proven to be an effective method for detecting and locating pipeline leaks, through the use of optical time-domain reflection measurement (OTDR) technology for localization. As a medium for temperature sensing, how to arrange and construct optical cables reasonably, e como colocá-los melhor e mais eficazmente em várias áreas de terreno especiais para garantir a qualidade da construção de assentamento são a base da precisão da medição de temperatura da fibra óptica e a principal prioridade para o uso eficiente na fase posterior.
O sistema de monitoramento de tubulação distribuída de fibra óptica usa fibra óptica como sensor para detectar pontos de vazamento na tubulação, monitorando mudanças de temperatura fora da tubulação. O princípio principal do sistema de monitoramento de dutos distribuídos de fibra óptica DTS é o efeito Raman. A luz espalhada Raman é causada por vibrações moleculares influenciadas pelo calor, e a luz retroespalhada carrega informações sobre a temperatura local na qual ocorre a dispersão.
O fibra óptica distribuída temperature measurement system mainly consists of a distributed fiber optic temperature demodulator and a temperature measurement optical cable. The distributed fiber temperature demodulator is a distributed temperature sensing system (ETED) that continuously measures the ambient temperature of the fiber optic. It uses advanced OTDR technology and Raman scattering light’s temperature sensitive characteristics to detect temperature changes along different positions of the fiber optic, achieving truly distributed temperature measurement and positioning. As a mature fiber optic distributed temperature measurement método, this device has the advantages of long measurement distance, alta precisão de medição, velocidade de resposta rápida, interferência anti-eletromagnética, portability, etc., and can be widely used for leakage monitoring of heating pipeline networks.
The main advantages of a distributed fiber optic pipeline leakage temperature detection system
1. The temperature measurement medium adopts armored optical cable, which does not require external power supply, convenient construction, and no need for later maintenance;
2. Fully monitor the pipeline network without dead angles in all directions, with real-time online monitoring for 24 horas. It can achieve simultaneous positioning of multiple leakage points, with a high positioning accuracy of up to 1m;
3. The platform software can accumulate big data and intelligently analyze to obtain the trend of changes in pipeline insulation effect.
