Outline of Approach• Deadlines from other group make
some tasks have priority over others
• Solution- Divide project into two parts
![Page 10: Ford/Lincoln Company ECEN 4610 Preliminary Design Review January 28, 2003 Oliver Mansour, Dan Spendley, Davy Odom, Lincoln Ritchie, Kelli Settell.](https://reader035.fdocuments.net/reader035/viewer/2022062713/56649ccf5503460f9499b03f/html5/thumbnails/10.jpg)
First Task: Clean Up Existing Data Signals
• Test current system for noise source(s)
• Reduce noise in system:– Using necessary wiring and shielding
techniques– Implementing noise filters
![Page 11: Ford/Lincoln Company ECEN 4610 Preliminary Design Review January 28, 2003 Oliver Mansour, Dan Spendley, Davy Odom, Lincoln Ritchie, Kelli Settell.](https://reader035.fdocuments.net/reader035/viewer/2022062713/56649ccf5503460f9499b03f/html5/thumbnails/11.jpg)
Second Task: Design and Develop New Component System:Signal/Power Conditioner
• Design and build constant current and voltage source to run sensor devices– Load cell, constant current– Accelerometer, constant voltage
• Localized signal conditioning– Implement hardware filtering– Signal amplification
![Page 12: Ford/Lincoln Company ECEN 4610 Preliminary Design Review January 28, 2003 Oliver Mansour, Dan Spendley, Davy Odom, Lincoln Ritchie, Kelli Settell.](https://reader035.fdocuments.net/reader035/viewer/2022062713/56649ccf5503460f9499b03f/html5/thumbnails/12.jpg)
Second Task: Design and Develop New Component System:
Controller
• Design and build controller box– Use “micro-processor” (Motorola 68H712?) – Provide brains for calibration– Eliminate need for DAQ card
• Localized data storage• Communication through serial port/RF
link

Design AlternativesInvestigate different micro-processor optionsUse varying amounts of hardware and software filtering
