  1. BC -1.0 By: Chad Harrington Sarah Steward

  2. The wording on this could be more clear and succinct Problem Statement Design and build a control system that can be implemented into an existing (Bascule) bridge system that will… • Water traffic will not have to wait to pass under the bridge during non-peak hours of automobiles. • Cost effective and towns will not have to pay for a draw tender • Ideal for small and medium port size towns • The bridges opening time will remain consistent to other bascule bridges. (Approximately 1 minute opening and closing times) • The bridge will sense presence of automobiles and boats to assure safety. • This bridge will not need human aid to operate.

  3. I edited this to be more clear and concise Solution Statement To build a realistic 3D model of an automated Bascule Bridge and river that will have… • Sensors (placed appropriately) to detect and control traffic of miniature boats and automobiles • A centralcontroller? to receive data from the traffic sensors and boat sensors to open the bridge at the correct time to ensure safety • Software for general control, including functionality to prioritize traffic of automobiles versus boats based on peak traffic hours

  4. System Overview

  5. Project Plan Subsystems • … • … • …

  6. What has been Completed Initial research on: • Inductive Loop Sensors • Ultra Sonic Sensors • Types of Draw bridges Other Development: • Tentative Flow Chart of… • Gantt Chart • System Overview • Decided on Type of controller

  7. Recent Progress: Bridge Research Swing bridge Lift Bridge Bascule Bridge

  8. Where we are what happens next? Chad: Research pricing for traffic sensors Sarah: Researching types of sound detection for boats audio signal

  9. Chad: Start to develop software for automobile sensing Sarah: Start to develop software for boat detection Where we are what happens next?

  10. Chad: Design framing layout for canal Sarah: Calculate the loads to determine the pressure on the bottom of the water canal Where we are what happens next?

  13. Background Information Bascule Bridges • Average opening and closing time = 1 minute • Operated by a Drawbridge attendant • Built to provide clearance for boat traffic, where stationary bridges would have too step of grades • Uses counterweights to help open and close

  14. Background Information • 33CFR117 Drawbridge Operation Regulations • Sec. 117.15 Signaling. • (a) General. • (1) The operator of each vessel requesting a drawbridge to open shall signal the drawtender and the drawtender shall acknowledge that signal. • (2) The signals used for requesting and acknowledging shall be sound signals, visual signals, or radiotelephone communications.

  15. Background Information • (b) Sound signals. • (1) Sound signals shall be made by whistle, horn, megaphone, hailer, or other device capable of producing the described signals loud enough to be heard by the drawtender.

  16. Background Information • (c) Visual signals. • (1) The visual signal to request the opening of a draw is-- • (i) A white, red, or green flag • (ii) A white, amber, or green lights

  17. Background Information • (d) Radio telephone communications. (1) Radiotelephones may be used to communicate the same information provided by sound and visual signals. • (3) When radiotelephone contact cannot be initiated or maintained, sound or visual signals under this section shall be used.
