  1. MTV Speed Synchronization & Position Control Client: Weiler Products (Knoxville, IA) Advisor: Timothy Bigelow

  2. Meet the Team Matthew Post Joseph Pins Jeremy evans Communications Team Lead Webmaster

  3. Understanding the System Hopper Conveyor MTV Paver Operation Video

  4. Original Project Proposal • Develop a speed control system for the MTV (Material Transport Vehicle) to maintain a proper distance ahead of the paver • Develop hopper material height sensor system to automatically keep the paver hopper full • Develop system to keep the MTV conveyor directly above the paver hopper to ensure material falls into hopper

  5. Deliverables • Design control system for speed synchronization • Design hopper tracking system (emphasis on offset paving) • Test each system for feasibility, make working prototypes for field test

  6. Modified Project • Still working with Weiler through ENGR 466 team • New project goal defined • Develop a prototype that can mimic our design concept on a small scale • Start with testing sensors

  7. Modified Project (cont.) • Using Vex Robotics structural parts to build our prototype

  8. Customer First • Technology research • RFID • Ultrasonic • GPS • Radar • Will also supply Weiler with Design Portfolio • We found ultrasonic sensor to be the most viable solution

  9. Design Concept • Design Considerations and Constraints • Affordable ( $1000 team budget) • Requires minimal modification to the paver • Rugged • Compatibility with existing controller OR

  10. Position Detection (Hopper Tracking) • Position detection using ultrasonic sensors and targets • Sensor array mounted on an adjustable bracket on top of end of conveyor Sensors Targets

  11. Design Concept • Position Control Using a PI Controller

  12. Control Simulation

  13. Control Simulation

  14. Conveyor Swing Control • Only enabled for tandem (in-line) paving • Use proportional control • Need to add encoder • Questions: • For what range of angles can we rely on small angle approximation? • Will the position controller adjust for angles outside this range?

  15. Operator Controls • Add to control panel • Momentary On/Off switch • “On” pilot light • Alarm • Options • Control begins from parked position OR… • Control is turned on after paving speed is reached like cruise control

  16. Project Status • Research completed and sent to ENGR 466 team • Test stand modeled, prints documented, controller up and running • GUI for sensor testing in progress • Banner sensors and Unitronics PLC just arrived

  17. Plans for Next Semester • Complete sensor testing in various conditions • Model prototype in Solidworks (summer) • Get ONE sensor to track a moving object • Start building prototype • Testing and refining

  18. Questions?
