【摘要】 在大型建筑的结构健康监测中,要对大量不同类型的传感器采集到的数据信号进行处理。基于Oracle数据库开发平台,根据各传感器的分类、采集的时间,建立相应的数据库系统。该系统能有效地对采集到的海量数据进行存储、管理、查询及异常数据的预警处理。将着重介绍该数据库系统的功能、特点、结构以及系统的框架组成,并以振弦式应变传感器采集到的数据信号的实例描述该系统处理海量数据的特点。更多还原

【Abstract】 In the structural health monitoring for large-scale constructions,a large number of different types of sensor data needs to be processed.Based on the Oracle database,according to the classification of sensors and the acquisition time,the corresponding database system was established.The system is effective for massive data storage,management and inquiry and can deal with the early warning of abnormal data.The article focuses on the function of database system,the characteristics of framework structure and the composition of system.The massive data acquired from a vibrating wire strain sensor were used as an example to describe the system characteristics.更多还原
