| 摘 要： | 历史数据的存储和查询对轨道交通综合监控系统具有重要意义.针对轨道交通综合监控系统通常只能保存几个月的历史数据且存储和查询速度慢的问题,根据轨道交通综合监控系统的特点,为RT21-ISCS综合监控系统设计了一种实时历史数据库FVDB.介绍了FVDB核心模块(点管理、实时数据管理、历史数据管理)的设计.FVDB能够在轨道交通综合监控系统海量信息的情况下,保存3年以上的历史数据并具有较快的存储和查询速度.

| Abstract: | The storage and query of historical data is significant for rail transit integrated supervisory control system(ISCS).Since the historical data could only be preserved for a few months in rail transit ISCS,and the speed of storage and query is also quite slow,FVDB—a real-time history database for RT21 ISCS is designed according to the characteristics of rail transit ISCS.Then the design of FVDB core module is introduced,which is for the real-time data management and history data management.FVDB is able to preserve the historical data for more than 3 years with higher speed of storage and query even encounters with mass information of rail transit ISCS. |
