Development and Application of Pipeline Optical Fiber Security Monitoring Information Management System

传统综合管廊的信息管理系统报警实时性低,缺乏大数据管理手段,无法满足光纤传感数据的管理需求。为了充分发挥光纤传感技术在管廊安防领域中的优势,设计并研发了适用于光纤传感技术的管廊安防监测信息管理系统。针对传统信息管理系统的不足,基于光纤传感技术特点,从实时性、大数据管理两个方面进行了设计,实现了更加实时、直观、准确的报警定位,提供了高效的数据管理、展示方式。本系统应用于珠海横琴综合管廊,运行期间内,基于电子地图的实时报警可以1 s定位故障,海量光纤传感数据能够持续、稳定地存储与查询,可用性高达99.99%。实践证明本系统不仅适用光纤传感技术,也可以低成本应用到已有管廊并兼容传统传感技术,具有一定的实用价值。

Due to the inferior real-time alarm performance and insufficient methods of big data management,the traditional utility tunnel Information Management System(IMS)cannot meet the management needs of optical fiber sensing data.The utility tunnel security monitoring IMS applying optical fiber sensing technology is designed to give full play to the advantages of optical fiber sensing technology in the utility tunnel security field.Based on the characteristics of optical fiber sensing technology,the IMS is implemented from the perspectives of real-time performance and big data management,achieves better real-time and higher accuracy alarm positioning,and improves data management efficiency and demonstration method.The IMS was deployed in a working underground utility tunnel in the Hengqin Special District(Zhuhai,China)last year,and has been functioning satisfactorily since.The practical application shows that the emergency repair efficiency of utility tunnel failure is improved significantly,and sustained massive data access of fiber optic sensing security is achieved.During the operation period,real-time alarm based on electronic map can locate faults in 1 second,and massive optical fiber sensing data can be stored and queried continuously and stably with availability of up to 99.99%.The IMS could be not only applied to optical fiber sensing technology,but also used in existing utility tunnel sensing technology at low cost.
