METHOD FOR UPDATING A PLURALITY OF VEHICLES AND ASSEMBLY FORMED BY A PLURALITY OF RAILWAY VEHICLES AND AN ASSOCIATED MANAGEMENT SYSTEM
First Claim
1. A method for updating a plurality of vehicles, each vehicle including an onboard server, a first electronic apparatus and at least one second electronic apparatus, the onboard server comprising a first memory and a radiofrequency communication module and each of the first apparatus and of the second apparatus comprising a controller and a second memory storing a set of initial data, each onboard server being connected to each of the first apparatus and of the second apparatus mounted in the same vehicle with a local internal communication network to the vehicle, wherein the method includes the following steps:
- transferring update data, through an extended radiofrequency communication network, from at least one server on the ground towards the onboard servers of the vehicles of said plurality, the updating data including modified data intended to be stored in memory by at least one of the first apparatus and of the second apparatus of each relevant vehicle,storing updating data in the first memory of each vehicle,wherein when the updating data have been stored in the first memory of each vehicle, the emitting through the extended network, by a server on the ground, an updating command intended for the onboard server of each vehicle, andtransmitting, for each onboard server having received the updating command, modified data to at least one of the first apparatus and of the second apparatus through the corresponding local network, the modified data replacing, in the second memory of said apparatus, the initial data.
