HIGH SPEED DIGITAL COMMUNICATION NETWORKS FOR HIGH INTERFERENCE CARGO TRANSPORTATION ENVIRONMENTS

摘要

A communication link arrangement for a cargo moving device (100) includes an electrical infrastructure mechanically coupled to the cargo moving device. The cargo moving device includes a cargo retaining structure (102) and a main body (104) coupled to the cargo retaining structure. The electrical infrastructure includes one or more conductors (116) and a single conductor electrically coupling the cargo retaining structure and the main body for delivering power and data signals between them.. A first networking element (112) is mechanically coupled to the cargo retaining structure and is electrically coupled to the single conductor. A second networking element (114) is mechanically coupled to the main body and is also electrically coupled to the single conductor. A high-speed network link over power line (110) carries data over the single conductor in the electrical infrastructure that supplies power between the main body and the cargo retaining structure.
