1 2011- Vermont Technical College Electro-Mechanical Senior Project Networked Advanced Vehicle Anti-Tamper & Alert System Tim Quinn, Jacques Dupuis, Henry Mossell

2  Background  Problem Statement  Solution Statement  Array Placement Concept  System Overview  Sensors Evaluated

3  Deployed Vehicles Unattended  Vehicles tampered with unattended  A vibration sensor is currently employed  Wide open spaces and wind gust  Not immune to vibrations due to wind  False alarms  Determine an actual threat from wind gusts

4  Check Feasibility for Different Sensors  Discrete Package  Robust  Water Proof  Easy to Replace  Sensitivity  5 Volt  Max current A  Detection is directly under the Vehicle

5  To design a system that uses a Passive Infrared Sensors to detect a real threat to the vehicle.  An array of PIRs shall be mounted in the under carriage to create a detection envelope directly under the vehicle.  The sensors will only be deployed when the alarm is activated.

7  Person crawls under vehicle to tamper with it  PIR detects persons movement under vehicle  Send threat verification signal to the CAN-Bus  Threat is detected
