Abstract: A wheeled fleet information processing and reporting system includes a hubmeter to be mounted on an axle of a vehicle that is being monitored. With each rotation of the wheel associated with the axle, an electronic pulse is generated and transmitted to a microcomputer. The microcomputer stores time data as well as rotation data. Periodically, at regular time intervals, the microcomputer reads the time from a built-in electronic clock and reads the accumulated rotation count total and stores the time and corresponding count total in memory. Periodically, an external reading device is placed in close proximity to the hubmeter and instructs the microcomputer to retrieve the contents of the memory, format the contents, and serially transmit them to the external reading device so that the data from the hubmeter may be processed and reprinted by the system to the user of the system for monitoring, controlling and maintaining a fleet of vehicles.
