P11210 – WOCCS: RF Test Bench Fall / Winter 2010-11 Team Members (from left to right) Michael DeFrancis – Computer Engineering Shaheer Khan – Electrical Engineering Andrew Nosal – Electrical Engineering Demetrios Koukouves – Mechanical Engineering Faculty Guide Philip Bryan Project Family Wireless Open Source Open Architecture Command and Control System Software Project Background This project is part of the Wireless Open Source / Open Architecture Command and Control System. The project family aims to create a modular system that transmits and receives basic data from a base unit to a remote unit. Power Meter • Arduino software streams power calculations over USB • GUI Reads incoming voltage, current, and power data over the USB serial port and graphs data in real-time • Toggles between different test modes such as voltage, current and power Objectives WOCCS Test Bench Control Station • GUI automatically detects devices and allows for manual configuration • GUI allows for monitoring of data transmitted and received • • • Creation of a test bench to test system level functionality Provide a test procedure for users who wish to test the WOCCS system Capability to interface with each WOCCS subsystem Capabilities • • • • • Range testing Data loss testing Latency testing Bandwidth testing Operating time testing • • • Electrical • • • Measures WOCCS system battery voltage and current draw Calculates instantaneous system power consumption Arduino Uno performs Analog to Digital Conversion, power consumption calculation and USB communication to the PC Provides interface for testing the WOCCS system Allows the user to upload / download files and perform bandwidth, data loss, and latency tests Communicates with WOCCS according to a serial protocol developed by members of each team Test Results • Validated that the test bench can successfully test bandwidth, data loss, latency, and range • The test bench successfully interfaces with the mid range 1 and the long range module • The operating time test for voltage, current, and power is not fully functional due to a complex grounding issue Conclusion • Team has accomplished overall scope of project and majority of primary customer requirements Future Work • Expand on testing capabilities for multiple modules being used simultaneously • Implement code to microcontroller of RF modules for easy integration with test bench • Develop subsystem test plan that can be verified without reliance on WOCCS modules Special thanks to our sponsor Customer Acknowledgements Dr. Edward Hensel Leo Farnand Dr. Andreas Savakis Vince Burolla Dr. Edward Hensel Dr. Dorin Patru Robert Kraynik
