Method and device for transmitting information over a complex network
First Claim
1. A method of transmitting a message by carrier current modulation over an electrical power distribution network having connected thereto a central unit or a zone unit together with a plurality of control/check modules that might be concerned by the message, the method comprising at least the following steps:
- initially allocating to each module an identifier such as the serial number of the manufacturer of the module and on installing the module in the network, associating said identifier with data relating to the geographical position of the location where the module is installed, so as to make it possible subsequently to identify the location of the module from its identifier, independently of its position in the network; and
when sending a message over the network to a module and/or to the central unit, recognizing and/or validating the message in the modules that are connected to the network and that are suitable for receiving the message, and systematically and synchronously repeating the message over the network by means of those modules that have recognized and/or validated the messages, this repetition of messages enabling other modules to become able to receive the message, and after recognition and/or validation, of resending the message in turn, such that from each repetition, other modules understand the message and are in a position to repeat it again, this process repeating until the message has been sent over the entire network and all of the modules have received the message and retransmitted it at least once.

Abstract
The method of the invention comprises firstly prior allocation of an identifier to each module that might be concerned by the messages transmitted over the network, and when the module is installed on the network, associating said identifier with data relating to the geographical position of the location where the module is installed, in such a manner as subsequently to be able to identify the location of the module independently of its position in the network, and secondly, when sending a message over the network to a module, the modules that are capable of receiving the message, recognizing said message, and modules that have received the message systematically and synchronously repeating said message until the message has been transmitted over the entire network and all of the modules have received and re-sent the message at least once.
