  2. Data Sources • Local Data Storage • Remote Data Viewing CU-NEES 2008 FHT Workshop

  3. Probably shouldn’t mention Neespop at all since it sounds like nada pasa CU FHT Equipment Network SCRAMNet Deterministic Optical Network (14) Gigabit Ethernet LAN (2 x Cisco 3550 Switches) (13) Neespop.Colorado.Edu Remote Collaboration Host Real-time Computation Target (OpenSEES/ETS or Simulink) NI Supplementary Data Acquisition and Control System A/D’s Test Specimen Neestp.Colorado.Edu Telepresence Portal and Robotic Camera Control Real-time Simulation Target (Simulink) D/A’s FPGA Additional Computation Resources Videoconference / Telepresence Hardware MTS Digital Control System A/D’s High-speed Actuators Neesdaq.Colorado.Edu Data Turbine Server Local Data Repository Real-time Hosts Valve Drivers Video/Still Image Sources CU-NEES 2008 FHT Workshop

  5. Robotic PTZ Video Cameras • Two fixed cameras at the north and south ends of lab • Two wireless cameras for experiment-specific viewing • Pan, tilt, and zoom controlled from telepresence portal • Video streams can be routed to Data Turbine server and viewed with the Real-time Data Viewer (RDV) • Up to 10 frames/second at 640x480 pixels CU-NEES 2008 FHT Workshop

  6. Robotic Still Image Cameras • Three Olympus C750 4.0 megapixel cameras on robotic pan/tilt bases • Controlled via LabVIEW GUI or web interface • Captured images fed into Data Turbine for viewing with RDV • Used for remotely viewing fine detail at low frame rates (10 seconds/frame) CU-NEES 2008 FHT Workshop

  7. MiniDV Camera • Canon GL2 Three CCD digital video camcorder with 16-bit stereo sound • Captured video edited and reformatted with open-source video tools (Kino, MJPEG Tools) • Reduced quality video can be streamed to Data Turbine in real time CU-NEES 2008 FHT Workshop

  8. Data Sources • Local Data Management • Remote Data Viewing CU-NEES 2008 FHT Workshop

  9. Local Data Flow MTS Digital Control System Researcher National Instruments Supplementary Data Acquisition and Control System Neesdaq.Colorado.Edu Real-time Streaming Data Local Data Repository NEES Central Repository Video/Still Image Sources 500 GB RAID 5 Disk Array OpenSEES and Simulink Real-time Hosts 2.5 TB Robotic Tape Library CU-NEES 2008 FHT Workshop

  10. Local Data Management • Data is moved from data sources to local data repository via network file system • Data from Data Turbine acquired with data sink tools • Local repository stored on redundant disk array with automatic tape backup • Data manually uploaded to NEES Central • Metadata manually uploaded to NEES Central CU-NEES 2008 FHT Workshop

  11. Data Sources • Local Data Management • Remote Data Viewing CU-NEES 2008 FHT Workshop

  12. 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 CU-NEES 2008 FHT Workshop

  13. 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 CU-NEES 2008 FHT Workshop

  14. RDV Time scale control Zoom timeline Real-time/ Pause control Global timeline Data Turbine server Numeric data graph Video channel list Numeric data channel list Video window CU-NEES 2008 FHT Workshop

  15. FlexTPS • Allows remote viewing and robotic control of live video over the internet using only a standard web browser • Digital Video Recorder (DVR) functionality allows video streams to be recorded and played back • Collaboration function allows video streams from local site and other NEES sites to be viewed together • Developed by University of Texas, Austin equipment site CU-NEES 2008 FHT Workshop
