 Motivation  Project Overview  Overview of Objectives  IR Camera Positioning and Electrical  Mechanical Design and Power System  Embedded System and Capture Cards  Software Design  Recommendations  Summary  Q&A

 Recent growth in wind power  10-40,000 bird deaths per year  Ethical and legal consequences  Economics

 Improve an existing system to gather info on migratory birds in the vicinity of off-shore wind turbines  Devices utilized: ◦ X-Band Radar – altitude ◦ IR Camera – x,y position  Record and use data to identify species

 Capture and timestamp video feeds from IR camera and X-band radar  Transmit video data wirelessly to remote computer  Accurate positioning of IR camera from a remote computer

 Used a stepper motor in lieu of a servo  Arduino Uno microcontroller  VEXTA motor driver  Tolerances

 Serial communication through USB port  Wrote firmware to communicate with C#  Single character commands to set rotation direction and step the motor  Used logic to control voltages of signals going to motor driver

 Selection of stepper motor ◦ Cost vs. Size  Holding Torque  Coupling  Bearing

 Components require 120VAC and 24VDC  Power supply selection ◦ Stepper ◦ IR Camera:16W Peak ◦ Required Wattage:86W ◦ Power Supply: 150W  Mains filter ◦ Used to prevent the noise generated in the driver from being transmitted externally via the power supply line

 Selection ◦ IR Camera  Winnov Videum 4100 AV ◦ Radar  Epiphan VGA2USB  Features ◦ Onboard Processing Power ◦ Support DirectShow

 Cost ◦ Custom Built vs. Pre-Built  Inputs/Outputs ◦ Capture Card Interface ◦ Networking Capabilities  Processing Power ◦ Video Encoding

 Three pieces of software were developed ◦ Video Capture Software ◦ FTP File Transfer Client ◦ Motor Controller Software  All software written in C#

 Provides a common interface to capture from both capture devices  Timestamps files accurately within 10ms  Uses DirectShow

 Uses FileZilla for FTP server  Wrote FTP client that automatically polls and downloads files

 Developed both a server and a client  Motor controlled via USB to Arduino  Can send commands both locally and remotely  Uses a network library called Lidgren  Movement constraints  Position messages

 Weatherproofing  Mechanical limit switch  Improve manufacturability  Printed Circuit Board (PCB) solution  Relocate movement command loop to firmware  Use of a better encoder

 Used frame grabbers to capture separate video feeds  Time stamped video for synchronization  Created FTP client to download video files to a remote computer  Used a stepper motor to obtain positioning accuracy within 1 degree  Created UDP server and client software for remote positioning of the IR camera
