Abstract
A control unit for a remote metering system of a mains supply system having plural consumer meter units arranged so messages can pass between the meter units and the control unit includes a router for determining routes to selected meter units via intermediate ones of the meter units. The router for each selected meter includes (1) a route table containing plural possible routes to the selected meter; (2) a route selector for selecting from the table different, previously untried routes; and (3) a route table updater. The untried routes are selected by the selector until one of them is successful, or until all untried routes are found to be unsuccessful. The route table updater generates a fresh route and inserts it into the table by displacing a single route from the table in response to the route selector detecting that all the routes in the table are found to be unsuccessful.
