Feb. 19, 2008 CU-NEES 2008 FHT Workshop Data Turbine Numeric and image data is fed into the Ring Buffered Network Bus (RBNB) “Data Turbine” Data Turbine is responsible for collecting and synchronizing data from data sources Synchronized data is streamed to Real-time Data Viewer (RDV) clients Synchronized data is also streamed to disk for later access

Feb. 19, 2008 CU-NEES 2008 FHT Workshop RDV Used to view real-time, streaming data over a network from a Data Turbine Server “Instant Replay” functionality with variable speed playback Synchronizes numeric, video, and still image data Allows user to overlay data from local PC onto streamed data Developed by Buffalo NEES equipment site
