1 1 Electrical and Computer Engineering Drebin Rescuing Firefighters in Distress FPR Team Ganz: Jonathan Bruso Michael Carney Daniel Fortin James Schafer

2 2 Electrical and Computer Engineering Outline  Background Motivation  System Requirements  Video  Users  System Components Drebin System Installer Tracking Software Incident Commander Interface  Demo

3 3 Electrical and Computer Engineering Background and Motivation:  Firefighters lives are endangered when going into burning buildings  Many firefighter have recently perished after becoming lost or unconscious in a burning building Worcester, MA 1999 (six killed) Bronx, NY 2006 (one killed) Charleston, SC 2007 (nine killed)  A system that can track firefighters in a building could aid in tracking and rescuing firefighters in distress

4 4 Electrical and Computer Engineering System Requirements:  Dynamically display firefighters position on a visual blueprint of the building Allow for the toggling of the path for each firefighter  Critical System, must be able to detect and recover from error quickly  User Friendly

5 5 Electrical and Computer Engineering VIDEO DEMO!!!!!

6 6 Electrical and Computer Engineering Users  Firefighter Carries RFID Reader and PDA  System Installers  Creating building blueprint using Drebin System Installer Responsible for placement of tags and system calibration Require average computer skills  Incident Commanders Exposed to Drebin Visual Display Features automated and require little computer knowledge

7 7 Electrical and Computer Engineering Our Design (1 reader and Multiple Tags): Tracking Done Using Active RFID Technology

8 8 Electrical and Computer Engineering Overall Design  Total System Software: 14,696 Lines of Code  Drebin System Installer  Tracking Software  Incident Commander Interface

9 9 Electrical and Computer Engineering Overall Design  Drebin System Installer : 3,793 Lines of Code  Tracking Software  Incident Commander Interface

10 10 Electrical and Computer Engineering Drebin System Installer Features  Used to design the floor layout of a building  Wall Creation Blueprint generation  Save/load Functionality  Tags placed on blueprint  System calibrated for individual environments  Room and Hallway Identification

11 11 Electrical and Computer Engineering Drebin System Installer Evolution  CDR  Current

12 12 Electrical and Computer Engineering Main Software Features:  Blueprint Analysis  Search for tags located:  Inside rooms  Inside hallways  Doorway tags  Room, Doorway, Hallway Connection  Find triangular orientation of tags  Required for trilateration

13 13 Electrical and Computer Engineering Overall Design  Drebin System Installer  Tracking Software : 6,610 Lines of Code  Incident Commander Interface

14 14 Electrical and Computer Engineering Tracking Software and Algorithms: Current status  Goal: Hallway and Room Tracking / Identification  Uses blueprint and tag layout created with Drebin System Installer  Signal Strength to Distance Alternative: Trilateration Signal Strength to Distance through walls High Accuracy Required for Distance Computation  Zone Analysis

15 15 Electrical and Computer Engineering Current Zone Algorithm  Two Tracking Modes  Both use signal strength to distance conversion Threshold for within 10 feet of each tag Signal strength to distance conversion within ft  Both use created Blueprint Hallway Tags Room Tags Transitional Tags

16 16 Electrical and Computer Engineering Hallway  Tags Placement: Every 30 feet down hallways  Region Between Hallway Tags calculated Uses Signal Strength to Distance conversion

17 17 Electrical and Computer Engineering Room  Rooms in Blueprints are zones  Tags Placement: Middle of room Within 5 feet of each doorway inside room  Transition detection determined by signal strength (10 feet threshold ) Entrance through doorway Entrance from Hallways

18 18 Electrical and Computer Engineering Tracking Software  Drebin System Installer  Tracking Software  Incident Commander Interface : 3,239 Lines of Code

19 19 Electrical and Computer Engineering Incident Commander Interface  Created after CDR  Uses Zone Analysis Data from Tracking Algorithm to display current position on Blueprint created using Drebin System Installer

20 20 Electrical and Computer Engineering Main Software Features:  Wireless Communication  Bluetooth connects to one PDA / Laptop  Data gathered and sent via WIFI to second Laptop  Second Laptop executes Tracking Software

21 21 Electrical and Computer Engineering Path Display:  745 Lines of Code  Path Construction and Replay  Traversed route calculated based of zones  Path save / load functionality  Replay  Toggle to specific point in time  Animate

22 22 Electrical and Computer Engineering Path Animation
