Due to the high-pressure operation of natural gas pipelines, the transmission medium is flammable, مواد منفجره, and toxic. Once an accident occurs, it will not only cause resource loss and environmental pollution, but also fire and explosion, resulting in huge economic losses and damaging the surrounding environment and personal safety. It is urgent to adopt high-tech means to timely and accurately measure changes in pipeline safety status, and it is particularly important to achieve real-time online monitoring of oil pipelines.
سنجش فیبر نوری توزیع شده technology is an emerging sensing technology that directly uses monitoring optical cables laid in the same trench as pipelines as sensors. It fully utilizes the continuous distribution of fiber optic space, ادغام می کند “انتقال” و “حس کردن”, and can achieve physical parameter information at any point along the fiber optic distribution. It has the advantages of rich measurement information, موقعیت یابی دقیق, و ایمنی ذاتی. علاوه بر این, fiber optic sensing technology uses light waves as carriers and optical fibers as media. در مقایسه با سنسورهای الکتریکی سنتی, fiber optic sensors have the advantages of high measurement accuracy, مقاومت تداخل الکترومغناطیسی, ایمنی ذاتی, compact and gentle design, and are suitable for remote transmission. They are particularly suitable for applications in fields such as power, نفت و پتروشیمی, حمل و نقل, پل ها, and dams. By laying the detection optical cable along the pipeline in the same trench or in parallel, real-time temperature, کرنش, ارتعاش (صدا) information can be obtained at any point along the pipeline, enabling real-time monitoring of abnormal conditions such as pipeline leaks, oil theft, بلایای زمین شناسی, و غیره. It has the advantages of long measurement distance, اندازه گیری مستمر توزیع شده, موقعیت یابی دقیق, simple installation, safety and reliability, strong scalability, و غیره. It will not cause any damage to the pipeline or affect its normal production, especially suitable for online monitoring applications of long-distance natural gas pipelines.
FJINO is based on advanced سنجش فیبر نوری توزیع شده technologies in the industry, such as Brillouin Optical Time Domain Analyzer (BOTDA) and Distributed Vibration Sensing Technology (THE). The detection optical cable is laid in the same trench or parallel along the gas pipeline to monitor the temperature, کرنش, and vibration (صدا) distribution around the pipeline in real time. When abnormal conditions occur locally in the gas pipeline, the distributed fiber optic sensing monitoring system can capture these abnormalities in a timely manner, display them on the distributed curve, and locate the location information of the abnormal points, which facilitates timely maintenance and handling by pipeline maintenance personnel and avoids major accidents.
ویژگی های distributed fiber optic monitoring system:
1. Real time acquisition of temperature, کرنش, ارتعاش (صدا) distributed information along the pipeline route;
2. Real time monitoring of leakage, external damage prevention, settlement deformation, and pipeline cleaning tracking and monitoring events along the pipeline;
3. Clearly indicate the location information of abnormal points;
4. Provide early warning and event development trends for abnormal pipeline/pipeline surrounding environment.
