US 2006/0213731 A1 · Method for data communication between a vehicle and a remote terminal

Abstract

An apparatus and methods are provided for data communications associated with a vehicle. The apparatus preferably includes at least one electronic subsystem associated with the vehicle and a plurality of electrical conductors connected to the at least one electronic subsystem and associated with the vehicle. A vehicle data communications protocol converter is preferably connected to the plurality of electrical conductors for converting a first data communications protocol associated with data communications along the plurality of electrical conductors to a second data communications protocol such as a local-area infrared or an RF data communications protocol. The apparatus also preferably includes a transceiver connected to the data communications protocol converter for transmitting the second data communications protocol from the vehicle and receiving the data communications protocol from a remote data communications terminal or another portion of the vehicle.

Dependent claims

A system for data communication associated with a vehicle comprising a tractor and:

at least one wheeled apparatus pulled by the tractor, said system comprising:
a first data communications apparatus associated with the tractor;
a second data communications apparatus associated with the at least one wheeled apparatus;
a power line carrier comprising at least one electrical conductor operatively interconnecting said first and second data communications apparatuses, said at least one electrical conductor comprising a data bus for transmitting data between said first and second data communications apparatuses;
a data communications protocol used for transmitting data along said data bus, the data comprising a plurality of data bits which transition between logic values indicating whether said data bus is in an active or an idle state;
and
a processor for interrogating data transmitted along said data bus to sense a transition in logic values and a change in said data bus from the active to the idle state.
