    摘要: A remote metering system comprises a multi-phase mains supply system (10) having a control unit (CS) and a plurality of single-phase consumer meter units (M1-M3) with messages passing between the meter units and the control unit. For phase determination, the control unit and each meter unit includes synchronizing means (CTR1) for synchronizing its message processing to its phase of the mains supply (or one particular phase, for the control unit). The relative phases of the control unit and a meter unit can then be determined, by a comparator (17), from the timing of a message passing between them relative to the phases to which those units are synchronized.

    摘要: A remote mains meter reading system comprises a mains system (10, 11, 13, 14), a central station (LC), and a plurality of meters (U1-U11) communicating with the central station by means of messages passed over the mains system. All of the meters act also as message forwarding (relay) units, but knowledge of the topology of the system (i.e. which meters can communicate with which) is known only to the central station. All messages are sent out by, and return to, the central station, the message format includes a list of meters through which the message is to pass. The central station can send out a variety of enquiry (SEARCH) messages to determine the system topology, assign labels to meters, etc. If the mains system includes link boxes coupling different areas together, these boxes preferably filter out messages and includes link units which controllably couple the different areas together.
