| Abstract: | The massive data concurrent control and storage problems faced by ISCS(integrated supervisory control system)of urban rail transit under FAO(fully automatic operation)mode are introduced.Then,the massive panorama data concurrent control and storage technologies,such as the distributed mode divided by domains,the key-valued real-time database accessed concurrently by multiple channels and the sequential historical database are proposed,in order to solve the massive real-time data processing and storage problems faced by ISCS.Through the performance test of ISCS with simulated data,it is verified that ISCS with massive panoramic data concurrent control and storage technology can meet the performance requirements of real-time data processing and historical storage under FAO mode. |
