  1. Science centerMay 10-16 Client: Dept. of EE/CprE (Vicky Thorland-Oster) Advisors: ManimaranGovindarasu Jason Boyd Team Members: Matthew Schulz (EE) Derek Bond (EE) Jun il Song (EE) Si-myung Yang (CPRE)

  2. Problem/Solution • Problem: • The EE/CprE Dept. Science Center has a group of exhibits but no way to conduct an organized tour. • Solution: • Make the room more automated in such a way that it interacts with the audience. • Organize the room in an interactive manner to ease the flow of the tour.

  3. Implementing Solutions • Make the room more automated • RFID • Central Computer (Labview) • Voice Command Software • Organize the room in an interactive manner • Video Monitors • Lighting • Demos

  4. Conceptual Sketch of the Command/Help Center Configuration

  5. Block Diagram – Schematic

  6. Room Layout

  7. Basic Components • Labview (Main program) • RFID Reader & Tag(s) • Light Control System • Surround Sound System • Video Distribution System

  8. Labview (Main program) • Labview will be the brains behind the central computer • Inputs • RFID Reader • Occupancy Sensor • Project Data • User • Outputs • Video • Lighting

  9. RFID Reader & Tag(s) RFID Reader RFID tags • RFID tags has an unique serial key • RFID reader can identify the serial key from RFID • RFID system does not have a memory space to store the data • It needs to be connected with the database

  10. RFID Requirements • Functional Requirement • RFID tags brought within 3 inches of the reader • Works with tags with EM4102 protocol • USB connection between RFID reader and computer • Tour guide data is stored in database • Non-Functional Requirement • RFID reader is attached to the wall next to the entrance • Every tour guide has a RFID tag

  11. RFID Reader & Tag(s) • Java Library for RFID • Phidget.jar • Java API for RFID • Class RFIDPhidget • Public void addAttachListener( AttachListener ) • Pulbic void addDetachListener( DetachListener ) • Pulbic void TagGainListener( TagGainListener ) • Pulbic void addTagLossListener( TagLossListener ) • BoolAntennaOn()

  12. RFID Test Result Without RFID tags With RFID tags

  13. Light Control System • Purpose • To highlight the project which is chosen to present to the tour group X10 control device X10 appliance device

  14. X10 device layout X10 signal sent through electricity cable Electricity cable Plug into outlet Plug into outlet Plug into outlet RJ11 cable connection Command through serial port RS232 serial cable connection

  15. Light Control Requirements • Functional Requirement • Every module needs to be connected with the power outlet • Electricity cable needs to be connected on the same circuit • Receive commands through serial port from the computer • Non-Functional Requirement • Lights shall be bright enough to get tour guide’s attention • The room will have enough lighting around the room to set the appropriate ambience

  16. RS-232 protocol • 8 data bits, no parity, 1 stop bit, 9600 baud. • This must precede all commands: • Send 0x02 to the X10 controller • The X10 controller will respond with ACK (0x06) if ready, NAK (0x15) if not ready. • The ACK will be followed by a carriage return (0x0D). The NAK isn’t followed with a carriage return. • After an ACK (0x06) and carriage return (0x0D) is received, the X10 controller is ready to accept a command.

  17. Light Control Example

  18. Surround Sound System • The system needs high quality sound card and speakers for clearer delivery to the tour group • Multi channel support sound card • 7.1 channel surround sound speaker system • Expandability for future groups

  19. Video Distribution System • Video output for the presentation will be output onto two separate large screens • We plan to use a simple video splitter to accomplish this task

  20. Optional Components • Speech Recognition Software • Touch Screen • Microphone

  21. Speech Recognition Software • E-Speaking Program • Two-Folded Operation • Give Vocal Commands • Speech Recognition • Guide User Through Tour

  22. Touch Screen • EloTouchSystems 1739L 17" LCD Open-Frame Touchmonitor • Secondary option to Voice Recognition • Used as System Back-up • Front-Mount Option

  23. Microphone • Omni-Directional Microphone with conference quality • Designated to work best for the speech recognition software. • Effective noise and echo cancelation • USB interface

  24. Test Plan • After each component is tested separately, to test the system we will run through various scenarios • Possible Scenarios • Registered tour group • Unregistered user • Multiple users • Someone in room when tour comes
