基于语义的隧联网数据整合方法

通过构建隧联网实现多个城市隧道监控系统的深层次数据共享与协同应用。隧联网可提供应急管理、城市规划建设和隧道长期监控等服务,实现各个城市隧道监控系统间的协同调度与联动控制;同时丰富物联网技术的应用,提高隧道联网智能监控水平。针对隧联网数据整合进行研究,首先通过构建隧联网联邦数据库实现各个城市隧道数据库的数据共享;然后给出标准化的隧联网数据字典;其次通过基于语义的数据整合方法实现隧联网数据的整合和查询。实现了隧联网数据的统一管理和关联性查询应用,其中的每个城市隧道监控系统实现数据的共享和信息互联,增加隧联网系统数据的利用率和信息的可信程度。

Research and Monitoring of Metro Tunnel Deformation based on the Technology of the Internet of Things

After a long subway tunnel operators will produce cross-sectional deformation. Articles designed vehicle laser ranging device tbr continuous measurement of tunnel wall to test their defomaed state. The paper also describes the tunnel cross-section deltbrmation measurement method, contour titting principles and error analysis and networking technology for wireless data transmission methods. The detection system is designed to achieve a tunnel section of the structural safety testing and deformation that may occur timely disaster warning, the safe operation of the subway tunnel to provide effective protection.
