A METHOD AND A DEVICE FOR COMMUNICATION OVER AN ELECTRIC DISTRIBUTION NETWORK

摘要

Method and device for communication via an electricity distribution network (10) in an establishment, whereby data signals are transmitted via network nodes connected to the electricity distribution network. Information about the physical location of the network nodes (11 ) and a unique identity for each network node (11 ) are stored in a storage unit (17) of a central unit (16) which is connected to the network nodes (11 ; 20). Certain network nodes (11 ) are wirelessly connected to mobile units (13; 14; 15; 27; 28; 29) and communication between the mobile units (13; 14; 15; 27; 28; 29) takes place via network nodes (11 ) and the electricity distribution network (10). Information exchanged between the mobile units (13; 14; 15; 27; 28; 29) is recorded and stored in the central unit (16). The central unit (16) is designed to convey necessary addressing in¬ formation to the network nodes and comprises a storage unit for recording and storing such communication information exchanged between the network nodes. A built-in network node (38) in an appliance (39) communicates with, controls and monitors via units (40-44) a piece of equipment connected to an electricity distribution network.
