2011- Vermont Technical College Electro-Mechanical Senior Project Networked Advanced Vehicle Anti-Tamper & Alert System
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
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.
Vehicle Node Threat Verification Sensor Tremble Sensor Array CAN compatible Microprocessor CAN Transceiver Voltage Regulator DAC Sensor Enclosure Vehicle
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
Waterproof IP68 Temperature compensated Power 10-30 Vdc @ 60 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
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.00108 bar
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
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
