Method and system for remote metering the consumption of electricity, water or gas
First Claim
1. A method of remote metering the consumption of utilities distributed through a public distribution network to a plurality of consumers, each consumer being associated with at least one remote meter, each of said remote meters including a program memory, a controller that executes programs stored in said program memory, and a data element memory that stores data elements indicative of the consumption of said utilities, said method comprising:
- each of the plurality of remote meters measuring a consumption of said utilities and storing utility consumption related data for reporting such data to a concentrator associated with saidplurality of remote meters,said concentrator communicating with said plurality of remote meters, collecting utility consumption related data, performing tasks concerning administration of its associated remote meters, transmitting a first request for status data to one of the plurality of remote meters, and transmitting a second subsequent request indicating an amount of utility consumption related data to said one of the plurality of remote meters, andsaid one of the plurality of remote meters transmitting said requested status data in response to the first request and subsequently transmitting said amount of utility consumption related data to said concentrator in response to the second request from said concentrator, said amount being determined at the collector on the basis of said status data received from said one remote meter in the first request,wherein the status data comprises one or more of a time value indicating a date and time of most recently measured utility consumption related data and an indicator indicating a storage location at the one remote meter of the most recently measured utility consumption related data.

Abstract
The method and devices for remote metering the consumption, of utilities according to the present invention provide the possibility to retrieve a specific amount of data, i.e. consumption data and/or additional data, from remote meters of a remote metering system. The retrieved data provide a data profile in a given time interval than the entire buffer, for example indicative of the consumption characteristics over time at the location of a remote meter or, in the case of a distribution network for electric energy, indicative of a ratio of active and reactive energy consumption at the location of a remote meter over time.
