1 2011- Vermont Technical College Electro-Mechanical Senior Project Networked Advanced Vehicle Anti-Tamper & Alert System

2  Deployed Vehicles Unattended  ARA designed a vibration sensing anti-tamper system  Threats tamper while unattended  Wide open spaces and wind gust  Not immune to vibrations due to wind  False alarms  Determine an actual threat from wind gusts

3  To design a system that uses sensors to differentiate between wind and a real threat to the vehicle, that can be used in harsh environments, robust enough to withstand constant vibration and impact, and easy to maintain.

5 Vehicle Node Threat Verification Sensor Tremble Sensor Array CAN compatible Microprocessor CAN Transceiver Voltage Regulator DAC Sensor Enclosure Vehicle

6 Tim Quinn Passive Infrared Henry Mossell Pressure Ultrasonic Jacques Dupuis Anemometer Pitot Tube After Testing each sensor Create a matrix table comparing the 4 sensors results Determine sensor of best fit for our application

7  Waterproof IP68  Temperature compensated  Power mA  RS-485 or RS-232  Sync Feature allows for 32 sensors  Range 3 meter optimum  Will detect a 9 cm disk at 3 meters

8  Absolute or Gauge  Stainless Steel  With 1 mA input 200 mV output at 2 bar  0 to 1000 bar  H-bridge  Not Temperature compensation  20 g max  30 mph gust bar

9  PIR sensors are detecting a change in radiation in its field of view  Sensor is split into two half and the IR levels are compared between the 2 halves.  If one side detects a higher IR radiation than the other side the output is pulled up or down  The use of a lens give a wider field of view as will a greater comparator sensitivity

10  Tim Quinn  ARA POC  Passive Infrared Sensor Research, design, and testing  Jacques Dupuis  Secretary  Anemometer, Pitot tubes Research, design, and testing  Henry Mossell  Project Manager  Pressure Sensor, and Ultrasonic Proximity Sensor Research, design, and testing Areas of responsibility are subject to change as the program progresses  Other duties may be assigned as required

11  Unlimited
