  1. FireFLIFireFighter Location Interface Design Presentation Derrick Bezanson, Kevin Calcote, Nat Coil, Janis Scott, Jason Whitaker, Ziggy Wolff

  2. Presentation Overview • Introduction • Project Description • Software Development • Hardware Development • Timeline/Budget • Testing • Demo (short video)

  3. Introduction • SAIC Sponsored Senior Design Project • Stemmed from the Internal Research and development Project UGSI (Ubiquitous GeoSpatial Intelligence) • There is a need to be able to monitor the location and status of first responders and military/civilian personnel in emergency or dangerous situations • GPS vulnerabilities: • Indoor / Underground • Multipath Interference • Jamming • Common approaches • Radio Frequency Triangulation • Sensor Fusion (Accelerometers, magnetometers, gyroscopes …) • RFID

  4. Our Vision • A Building is on fire!! • Create a location monitoring system for first responders. • Allow the user to know where he/she is at all times • Provide “Situational Awareness” • Room Status • PANIC Transmitter / Receiver Firefighter Transmitter / Receiver Firefighter Escape Route Monitoring Base Stations Transmitter / Receiver

  5. Our Solution • Sensor Integration in a Handheld Device • Zigbee Networking Modules • UHF RFID reader • Passive RFID tags provide location information • This device requires minimum user interaction • Graphical User Interface Base Station • Outside monitoring and control • Location and room status is saved in a database

  6. Our Solution RFID TAG RFID ANTENNA BASE STATION ZIGBEE ANTENNA Display Updated!!!

  7. Base Station

  8. Base Station Receive & Respond 1) RX: Tag Scan TX: Distance/Direction to Exit 2) RX: PANIC Mode ON TX: Broadcast PANIC to all 3) RX: Door Tag Scan TX: Danger Status of the room

  9. Zigbee/Mesh Network • Zigbee: • A protocol that uses the IEEE 802.15.4 standard as a baseline and adds additional routing and networking functionality. • Developed by the ZigBee Alliance to add mesh networking to the underlying 802.15.4 radio. • Advantages: • Low power -> long battery life • Secure networking • Star & Mesh networking capabilities • Range of approx 100m indoors

  10. RFID – Skyetek M9 • Antenna Gain vs. Tag Read Range: Note: A higher gain increases read range but through a smaller beam.

  11. Software Block Diagram

  12. PIC Programming RFID Process • Set to occur on a timer interrupt (approx. 1 Second) • Send a scan command over the SPI interface • Receive the response packet, and decide if we received a Tag ID. • If a Tag ID was scanned then it is sent over the Zigbee network. • If no tag is scanned, no action is taken.

  13. PIC Programming Zigbee Receive Process • Wait for an interrupt to occur on the UART • Dynamically allocate space and store the packet byte by byte as it arrives. • Parse the packet looking for three operations • Set danger level • Set distance and direction to exit • Set panic mode

  14. PIC Programming Zigbee Transmit Process • Poll for a button press • Determine what button was pressed • Set danger of current room • Panic • Send packet pertaining to relative button press • If there is a RFID tag ID waiting to be sent then that will be transmitted as well.

  15. Block Diagram of Schematic

  16. Power Supply • Requirements • Battery Operated – High Efficiency • Two different voltage levels • 5.0V • 3.3V • Current up to 1A • Low Noise

  17. Power Supply

  18. PCB Design

  19. Production >1K Prototyping Cost: $510.72 (4 units)

  20. Project Plan Major Milestones • February: • Researched and decided on important parts • Came up with preliminary design, block diagrams, budget, and project plan • March: • Zigbees sending/receiving packets with UART interface • RFID reader up and running with SPI interface • Zigbee & RFID interfaced with PIC microcontroller • April: • Added buttons, switch, & LCD to handheld • Completed PCB layouts, constructed handhelds • Base Station, & handheld software completed • Fully functioning system!!!

  21. Testing • Power Supply and PCB integration • Tested battery under normal conditions for 7 hours • Zigbee communications • Point-to-Point range testing greater than 100 feet indoors • Update time less than 5 seconds • Mesh network testing works with 6 zigbees • RFID • Hallway test to be determined • Base Station Software • Software is fully functional

  22. Testing continued Corresponding tags have been placed on both sides of the hall

  23. Looking Ahead • Future development could include • Additional Sensors could be added • Magnetometer for direction • MEMS IMU for navigation • Additional Base Stations for RSSI triangulation • Hands-free device • Integration with existing firefighter sensors (life alert) • Voice controlled/audio feedback • Heads up Display • Adaptable to other applications • Indoor route plotting • Provides last known location • Equipment tracking

  24. Demo Video • …
