The invention is directed to a data collection and evaluation system that
includes an active RFID tag for collecting, time-stamping, and storing
vehicle sensor data. Examples of the type of data collected include door
data, ignition data, oil pressure data, temperature data, speed data,
global positioning data, and diagnostic and trouble code data. The system
further includes an external data acquisition device, such as a mainframe
computer system or a hand-held data acquisition device like an iPAQ. The
external data acquisition device includes an RFID interrogator for
communicating with the RFID tag, which enables the RFID tag to transmit
the time-stamped data wirelessly to the external data acquisition device.
The ability of the system to automatically collect and transfer data
allows for the automation of fleet management processes, vehicle
maintenance and repair processes, and certain security features.
