  1. CMU–Voyager • Instrumenting for Pollution and Energy Consumption

  2. Team Members Pratik Agarwal Alex Eiser Gary Feigenbaum Yuan-Ning “Richard” Hsieh Gregor Kronenberger Kietae Park Asad Samar Kristen Stubbs

  3. Overview

  4. Overview:Goals • Instrument Voyager to monitor • Propulsion power generation • Energy Consumption • Energy Efficiency • Fuel Consumption

  5. Overview:Goals • Provide a means to view this data • For instructors: • Teaching tools • For the crew: • Visualize the information gathered • Provide ability to perform basic analysis • Provide insights for the new Voyager

  6. Overview:System Architecture • Three subsystems • Network of sensors • Fuel flow rate • Electricity sensors • GPS sensor • Scientific visualization tool for the crew • “Dashboard” interface for students

  7. Overview:Design Process • PHASE I: • Understand the problem • Create a visionary scenario • Propose an initial solution PHASE II: • Create a concrete design • Start on implementation • Discover and solve problems • Update design PHASE III: • Complete implementation • System integration and testing • Demonstration

  8. Final Prototype • Application Launcher

  9. System Architecture: Application Launcher

  10. System Architecture: Application Launcher Wait until Status turns green Launch Dashboard

  11. Final Prototype • Dashboard

  12. Final Prototype • Scientific Visualization

  13. Data Visualization:Single Dimension • Web interface to view data • Works in IE 6/ Opera 7.5/ Mozilla • Requires Javascript for date selection • Shows one-dimensional data vs. time

  14. Data Visualization • Choose Sensor • Speed • Electrical • Fuel consumption • Not pollution

  15. Data Visualization • Select date • using a dropdown • using the calendar

  16. Data Visualization • Select date • using a dropdown • using the calendar

  17. Bar Charts: Fuel Consumption vs. Time

  18. Line Charts:Fuel Consumption vs. Time

  19. Two Sensors:Fuel Consumption and RPM vs. Time

  20. Excel Export • Link in graph display • Exports directly to an Excel file for further analysis

  21. Excel Export • Link in graph display • Exports directly to an Excel file for further analysis

  22. Excel Export • Link in graph display • Exports directly to an Excel file for further analysis

  23. System Architecture • Overview

  24. System Architecture

  25. System Architecture • Sensors

  26. System Architecture:Device Placement

  27. Electrical

  28. System Architecture: Sensors

  29. Current Sensors • Self-powered so can be left permanently running • Output between 0-5V depending on the current flowing through the wire • No need to expose the conductor

  30. Electrical Subsystems Shore Power Main circuit panel (hallway) AC/Lights/Heating Generator Switchover panel Main distribution panel Ventilation Pumps MSD

  31. Sensor Placement Shore Power Generator Main circuit panel (hallway) A/C Heating Ventilation Pumps Flushing Sink Sink Switchover panel Main distribution panel Ventilation Pumps MSD

  32. Experiments, first in lab and then on the boat show they are pretty accurate All data collected in real time now Seven electrical sensors (worth approx. $700) Current Sensors

  33. Current Sensor Installation • Current sensors have been installed on the boat, to monitor the following: • A/C: 3 units in the main classroom • Heating: 2 units in the main classroom and 1 in pilot house

  34. Current Sensor Installation • Toilet pump: monitors the toilet • Engine pump: The bilge pump in the control room • Ventilation: Ventilation switch in the control room

  35. Flow Rate Sensor

  36. System Architecture: Flow Rate Sensor

  37. Constantly monitor one engine Either engine combination can be monitored Real time data Will not block fuel line Can be installed permanently Powered by 12V DC Easily accessible from sensor position 0-5V output Use Data Acquisition Device to collect data Approx cost $1,100 Flow Rate Sensor:FloScan

  38. FloScan

  39. How FloScan Works Engine Fuel Tank

  40. FloScanInstallation • Forward and Return sensors were placed in fuel line • Wires were run to the starboard side under the floor • Wires are not visible for 90 % of path and do not interfere with engines

  41. FloScanInstallation • The monitor is mounted on the starboard side wall • Wires run to the 12 V DC power supply and to the DAD

  42. Data Acquisition

  43. Data Acquisition: Data Acquisition Device

  44. Data Acquisition:Data Acquisition Device • 0-5V input • 11 channels • RS232 output • Requires power supply, some interface cards and cables

  45. Data Acquisition:Data Acquisition Device • Experiments in the lab and on the boat have shown that this works fine with the current sensors • 1 device costs $90 with the power supply.

  46. Data Acquisition:Installation • DAD has been installed on the boat. • Input from flow rate and current sensors, output to PC

  47. Data Acquisition: I/O module
