Abstract

A system for the remote acquisition of data and for the remote control of electricity meters comprises a central server AMM in bi-directional communication with a plurality of concentrators. To each concentrator, a set of electricity meters is connected, such that bi-directional communication between each meter and its associated concentrator is possible. The intelligence of the system is distributed between the central server, the concentrators and the electricity meters. To this end, each meter comprises at least a first processor, a first data memory and a first program memory for bi-directional communication with the associated concentrator. The first data memory serves to at least temporarily store and/or transmit the data which have already undergone a first processing by the first processor. Each of the concentrators comprises a second processor, a second program memory and a second data memory as well as means for a bi-directional communication with a central server. The second data memory serves to temporarily store and/or transmit the data processed by the second processor.
