Telematics: Interactive Display Using Wireless Communication Jimmy Su Team Whitney April 29, 2002 Wireless Communication System • Allows communication between Whitney and separate vehicles/computers • Processes the data using Visual Basic programming • Displays the data through a Graphical User Interface E Wireless Communication System Two RF Transceivers that transmits and receives wireless RS232C Data Process: One Transceiver accepts RS232c data and converts the data to Radio Frequency. The other Transceiver receives the RF data and converts it back to RS232c Wireless Transceiver: Specifications OTEK TR200 Series Transceivers • 100/300 feet range • 916.5 MHZ Operating Frequency • Transmission Rate of 19,200 BPS Wireless Transceiver: Circuit Diagram Wireless Communication: Protocol Sender’s Protocol • Proprietary software made by OTEK, manual input that runs on DOS Receiver’s Protocol • Program developed in C that parses control and input data, reads and writes to the serial port Interactive Display: Visual Dashboard Purpose: To display real-time information from Whitney to a computer on a separate vehicle Visual Dashboard: State Algorithm Start Load Form Process Data User presses GO Get Input End of End Input Telematics: Summary • Wireless Communication proved to be successful, however the proprietary software became a limitation • Visual Dashboard Interface can display the information from Whitney, what is the next step? • Automotive Telematics has become the new trend in traveling: enabling safety, security, entertainment, and navigation
