Portable Locators—Versatile Applications in Complex Oil & Gas Pipelines
摘要: 为解决复杂油气管道场景中光缆巡护的效率与精度问题，本文基于理工光科自研的便携式巡缆仪DVS-2100-P，结合陕西天然气便携式巡缆仪试点项目，研究了分布式光纤振动监测技术的应用方法。较传统增强型OTDR，系统集成了振动在线监测模块与高精度OTDR，采用MQTT移动端数据架构，实现了70 km范围内的实时在线监测与10米级定位精度，大幅提升了复杂油气管道巡护的效率与精度。通过断点查找、盘缆确认、光缆路由定位等多场景试验，验证了该设备在复杂地形与油气管道运维中的实用性与高效性。研究结果为便携式DVS系统在能源管网巡检中的推广应用提供了技术支撑与实践经验。
Abstract: To address the challenges of efficiency and accuracy in optical cable inspection for complex oil and gas pipelines, this study utilizes the DVS-2100-P portable fiber optic inspection system developed by LITG Optics. Building on the Shaanxi Natural Gas Pilot Project for portable inspection devices, we investigated distributed fiber vibration monitoring technology. Unlike traditional enhanced OTDR systems, our innovation integrates vibration detection modules with high-precision OTDR capabilities through a mobile MQTT architecture. This breakthrough enables real-time monitoring across 70 km ranges with 10-meter-level positioning accuracy, significantly enhancing pipeline inspection efficiency. Field trials across multiple scenarios—including fault detection, cable routing verification, and optical fiber positioning—demonstrated the system’s practicality and operational effectiveness in complex environments. The research provides technical validation and practical insights for implementing portable DVS systems in energy pipeline maintenance.
