Embodiment Construction

[0024] figure 1 An embodiment of a power distribution network 1.2 is depicted. A first device 1.1 acting as a data concentrator is connected to the network. In an exemplary embodiment of the invention, the device 1.1 also has the function of a CIASE client in the sense of NF EN 61334-4-511, that is to say, the device will also be responsible for assigning MAC addresses to the connected network equipment. A certain number of devices are shown with reference 1.3. Typically, these devices are electricity meters C1 to CN used to measure the amount of electricity consumed by each subscriber. Although these devices are described as electricity meters, these devices can be any type of device that communicates with the device DC 1.1. In the context of the exemplary embodiment, the DC is responsible for collecting consumption data from the electricity meters 1.3 to feed back the information system of the operator managing the electricity distribution network.

Abstract

In the field of the allocating of communication addresses to devices connected to a carrier-current communication network and more particularly, networks for the remote reading of electrical meters from a data concentration apparatus through the electrical network, there is proposed an improved method of allocating MAC addresses for this type of network making it possible to save a great deal of time during the address allocation phase. This method proposes in particular that a list associating the serial numbers of the devices and the MAC address allocated be stored at the level of the central device for allocating addresses. It is also proposed that a cataloguing request be sent, serving to allocate the MAC address prior to the sending of a communication frame.

Description

technical field [0001] The invention relates to the field of assigning communication addresses to devices connected to a power line communication network. Specifically, these are networks of electricity meters that are read remotely from data set instruments through the grid. Background technique [0002] It is well known to remotely read data from watt-hour meters operating on the grid. This is usually done by means of reading and compiling summaries of a computer network (such as a distribution operator's invoicing network). This device is referred to by the term "DC" (Data Concentrator, representing a data concentrator). [0003] In order to be read remotely, the watt-hour meter has a current-carrying communication interface. The interface memory has the serial number engraved on the instrument. This serial number forms the unique permanent identification of each meter. [0004] The communication on the current carrying is performed by means of modulated data frames ...
