    Abstract: A powerline communication system includes a plurality of rail segments. Each of the rail segments is electrically isolated from other rail segments, and each receives power from a rail segment power supply. At least one cart operates on the rail segments. The cart has a powerline communications controller. Each rail segment has a current state defined by how many and which carts are operating on the rail segment. A central coordinator is coupled to each rail segment and configured to execute a channel estimation using a sounding protocol on its rail segment. The central coordinators store tone maps associated with the possible states of its rail segment, and possibly its adjacent rail segment. A main controller communicates with each central coordinator to direct the state and future state of its segment so that tone maps and network keys can be managed by the CCo in advance of an imminent state change. The main controller or CCo may also execute channel estimation using a sounding protocol and cause updated tone map information to be sent to each central coordinator in advance of an imminent state change.

    Abstract: A powerline communications apparatus includes a transceiver communicating over an electrical power distribution wiring of a vehicle and a communications interface carrying a first and second PLC message in a first communication protocol having a PLC automotive network delimiter type, a PLCAN variant field comprising a number of users, user identifications, payload length, payload data, and a repetition number corresponding to a number of times the first PLC message is transmitted over the electrical power distribution wiring, and a first payload for a first user. The PLC apparatus also includes a processor and a non-transitory computer-readable medium storing programming for execution by the processor. The programming includes instructions for transmitting the first PLC message using the transceiver, determining if the vehicle is in motion, and switching between the first and the second communication protocol based on whether the vehicle is determined to be in motion.
