摘　　要：为深入挖掘桥梁数据潜在信息,识别数据异常,通过将桥梁结构监测系统异常数据进行分类,并结合系统在辽河大桥养护工作中关于“异常数据”方面的数据分析与应用经验,针对不同类型数据异常进行成因分析。对于监测系统出现的“异常数据”和“误报警”现象,在系统硬件设备和软件功能方面分析研究,加强系统对异常数据的主动识别、智能分析、自动过滤等功能,以减轻现场核查及排查的工作量,进而大幅度提升养护工作效能。In order to deeply explore the potential information of bridge data and identify the data exception,the abnormal data of the bridge structure monitoring system is classified,and the causes of different types of data exception are analyzed in combination with the data analysis and application experience of the system in the maintenance work of Liaohe bridge on"abnormal data".For the phenomenon of"abnormal data"and"false alarm"in the monitoring system,the hardware equipment and software function of the system are analyzed and studied,the functions like active identification,intelligent analysis,automatic filtration and so on of the system for abnormal data are strengthened,so as to mitigate the workload of on-site inspection and troubleshooting,and greatly improve the work efficiency of maintenance.
