基于物联网和云计算的高速铁路桥梁状态监测预警系统设计

摘要

In order to promote the reliability of the safe operation for high-speed railway bridge. The thesis is based on the theories of internet of thinys and technologies of cloud computing, monitoring and inspection of the operational status of bridge, data processing, status assessment and risk pre-warning are researched. Pre-warning system of monitoring high-speed railway bridge is designed, integrated with daily management and maintenance, monitoring and early warning as well as emergency disposal, which adopts sensing equipment to collect different information about bridge’s operation in real time for a long term. Mass data is input to data processing server through communication technology. Then, data processing server transmits the data to central server of cloud computing through internet. It is the third-party professional agencies that provide cloud computing services like data assessment and risk pre-warning, and the results of assessment and pre-warning are transmitted and displayed in the visual monitoring terminal of information data disposal platform. Fi-nally, it is bridge maintenance agency that is in charge of the repair and maintenance. This system can monitor the oper-ational status of high-speed railway bridge in real-time for a long term, provide risk pre-warning of bridge, put forward the emergency disposal scheme and eliminate the potential risk.%为提升高速铁路桥梁结构安全运营可靠度，基于物联网概念和云计算技术，研究了高速铁路桥梁运营状态监测检测、数据处理、状态评估及风险预警等理论和技术；设计了集合日常管养、监测预警、应急处置等为一体的高速铁路桥梁运营状态监测预警系统，即采用传感设备长期实时采集桥梁运营状态各项信息；使用通信技术将海量数据输入数据处理服务器。后者通过网络将数据传输至云计算中心服务器，由第三方专业机构提供数据评估与风险预警等云计算服务，并将评估和预警结果传输及显示于信息数据处理平台的可视化监控终端，最终由桥梁养护机构负责执行养护维修等处理措施。该系统可以长期实时监测高速铁路桥梁运营状态、提供桥梁风险预警、提出应急处置方案，消除安全隐患。
