  1. Educational Laboratory Virtual Instrumentation Suite (ELVIS) • May 03-19 • Client: National Instruments • Advisors: Dr. Mani Mina, Dr. Diane Rover • Group Members: • Michael Ballou – CprE • Ryan Hankins – EE • Jason Salz – EE • David Schmidt – CprE • Dayu Zhou - EE • 30 May 2003

  2. Outline • Introduction • Project Overview • Project Activities • Resources and Schedule • Summary

  3. Definitions • Educational Laboratory Virtual Instrumentation Suite (ELVIS) – A hardware data acquisition system • Data acquisition (DAQ) – The process of collecting and measuring electrical signals from sensors and transducers and inputting them to a computer for processing • LabVIEW – A graphical programming language used for creating test, measurement, and automation applications, developed by National Instruments

  4. Acknowledgement • David Gardner • Randy Hoskin

  5. Problem Statement • GeneralBackground • Convert current EE lab to ELVIS • Document the conversion process

  6. Problem Statement

  7. General Solution • Redo EE 201 labs • Write instructions for students • Find volunteer to follow the instructions • Develop new interfaces • Test • Document the conversion process

  8. Operating Environment • Standard laboratory condition • Indoors • Clean air • PC with Windows

  9. Intended User and Uses • User • Instructors or TAs who intend to use ELVIS in their circuit or electronics labs • Uses • Help users with conversion process

  10. Assumptions and Limitations • Assumptions • ELVIS bundle from NI in working condition • The group can create virtual instruments that are not provided • Limitations • No current or inductance measurement capacity • Measurement inaccuracy • Limited knowledge of internal design

  11. End-Product Description and Deliverables • Selected labs will be converted to ELVIS system • New instructions for selected labs • Documentation of conversion process

  12. Present Accomplishments • Familiarity with ELVIS hardware and software • Carried out EE 201 labs 1, 5 and 6 with the ELVIS system • Produced new documentation for completing EE 201 labs 1, 5 and 6 with the ELVIS system

  13. Approaches Considered and Used • Considered • Creating new virtual instruments • Individually converting every lab for use with ELVIS • Used • Decided to use Virtual Instruments provided by NI for their ease of use and functionality • Focused on key labs which made use of different features of ELVIS

  14. Research and Design Activities • Research • Read National Instrument’s ELVIS manual • Researched how others are using ELVIS • Design • Updated labs to make use of unique capabilities present in the ELVIS system

  15. Implementation Activities • Took notes as we implemented several EE 201 labs using ELVIS • Created new lab instructions for the labs that could be completed with ELVIS

  16. Testing Activities • Asked a EE major to follow our new lab instructions • Asked a ChemE major to follow our new lab instructions • Reviewed our own instructions to ensure completeness • Tested the accuracy of ELVIS

  17. Test Results

  18. Personnel Effort

  19. Financial Budget

  20. Project Schedule

  21. Project Evaluation • Analyze necessary virtual instruments (100%) • Completion of virtual instrument interface (100%) • Completion of necessary documentation (100%) • Completion of testing (100%) • Revision (100%) • Working demonstration of ELVIS (100%)

  22. Closing • Commercialization • No commercial application • Used by ECpE department • Additional Work • Re-evaluate ELVIS using non-prototype unit • Lessons Learned • Time Management • Team Communication • Risk Management

  23. Summary • Project Goals • Evaluate ELVIS for ECpE • Document conversion process • Approach Taken • Utilize tools provided by NI • Preserve educational concepts taught in lab • End Result • Sample of EE 201 labs • Conversion documentation

  24. Questions • ?
