SYSTEM AND METHOD FOR DISTRIBUTION OF ELECTRICAL POWER AND CONTROL DATA IN TEMPORARY LIGHTING INSTALLATIONS

摘要

An AC circuit PLC injection module of a PLC-enabled power and data distribution system (300) includes: an AC power input (307) to receive an AC power signal; a PLC transceiver circuit (430/440) to couple a PLC signal onto the AC power signal; an AC circuit (411) to supply the AC power and the PLC signal; and a PLC blocking line filter (450) to filter the PLC signal from passing to the AC power input. An associated method for a system having plural PLC transmitters connected to plural PLC enabled devices via plural AC circuits each associated with one of the PLC transmitters, includes: setting PLC network IDs for each of the PLC enabled devices to a default PLC network ID, and then assigning each of the PLC enabled devices connected to each of the PLC transmitters to a PLC network ID uniquely assigned that PLC transmitter.

1. A system, comprising:
at least one AC circuit power line communication (PLC) injection module, the AC circuit PLC injection module comprising; an AC power input configured to receive an AC power signal; a PLC transceiver circuit configured to couple a PLC signal onto the AC power signal; at least a first AC circuit output configured to output AC power and the PLC signal; a PLC blocking line filter configured to filter the PLC signal from passing to the AC power input; a power relay connected between the AC power input and the at least one AC circuit output; and a processor configured control the power relay to selectively enable the first AC circuit to output power, and disable the first AC circuit output from outputting the AC power, during a process of assigning PLC network IDs to PLC enabled devices which are connected via the AC output circuit to the at least one AC circuit PLC injection module.
