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.

Implementing Solutions

Labview (Main program)

Labview will be the brains behind the central computer

Inputs RFID Reader Occupancy Sensor Project Data User

Outputs Video Lighting

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

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

Light Control System

Purpose To highlight the project which is chosen to present to

the tour group

X10 control device X10 appliance device

X10 device layout

Electricity cable

RJ11 cable connection

RS232 serial cable connection

Plug into outletPlug into outlet

X10 signal sent through electricity cable

Command through serial port

Plug into outlet

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

RS-232 protocol

8 data bits, no parity, 1 stop bit, 9600 baud.

This must precede all commands:

1. Send 0x02 to the X10 controller

2. The X10 controller will respond with ACK (0x06) if ready,

NAK (0x15) if not ready.

3. 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.

Light Control ExampleComputer X10 control device

0x02 [start command ] 0x06 [ACK ] 0x0D [carriage return ]

0x63 [send X10 command ] 0x46 [house code ‘A’ ] 0x4C [unit code ‘1’ ] 0x45 [function code ‘On’ ] 0x41 [repeat command once ]

0x58 [transmission received ] 0x46 [house code ‘A’ ] 0x4C [unit code ‘1’ ] 0x31 [sent once ] 0x0D [carriage return ] 0x58 [transmission received ] 0x46 [house code ‘A’ ] 0x45 [function code ‘On’ ] 0x31 [sent once ] 0x0D [carriage return ]

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

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

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
