Abstract (en)
The proposed system for managing a lighting plant by radio-frequency networks, where the lighting plant includes a plurality of groups of loads (Lj1, ..., Ljm) distributed in corresponding elementary areas (Aj), includes substantially: a co-ordination control unit (W), which is situated near the elementary areas (Aj) and interacts with the loads (Lji) of a related (j-<th>) group through radio-frequencies networks; a plurality of support control units (Wj), which are situated near the elementary areas (Aj) and interact with the co-ordination control unit (W) and the loads (Lji) of a related (j-<th>) group through the radio-frequencies networks. <IMAGE>
