A system to communicate via modulated optical signals of the Li-Fi signal type to transmit data to and from a plurality of defined privileged spaces. The communicating system includes a plurality of first light sources, each first light source emitting, in the infrared, a first modulated optical signal. A plurality of optical fibers, each optical fiber guiding the first modulated optical signal from a single first light source in the direction of an optical interface. The optical interface transmitting the first modulated optical signal into a defined privileged space. Each optical fiber also transporting a second modulated optical signal from the associated defined privileged space in the direction of a device configured to acquire the second modulated optical signal.

System for communicating via signals of Li-Fi type

A data management structure () on board a transportation device, incorporating a cabin () provided with seats (), includes a data resource block () incorporating audiovisual transmission system units (to), outward communication systems () and/or cabin systems, a standardised data distribution architecture (), and devices (Eto E) for operating said systems. In the structure (), the standardised architecture () includes a concentration box () for the bidirectional transfer, on the one hand, of base signals with the resource block () and, on the other hand, optical signals with the devices (Eto E) of the cabin () on at least one optical fibre (). This concentration box () houses units for processing (to) by signal switching, bidirectional conversion into optical signals, and optical signal management by wavelength allocation and distribution of downstream (F) and upstream (F) optical flows. This concentration box () is connected to the devices (Eto E) of said systems via intermediate boxes () also housing processing units (to) according to the devices (Eto E) to which they are connected.

Method for managing data in a transportation cabin and standardised implementation architecture

The invention relates to the on-board electric power network architecture of a vehicle cabin using domestic devices, in particular of an aircraft cabin, including primary networks () connected in parallel to a single domestic network () of the cabin for powering domestic devices via converter units (). Measurement sensors () are arranged at the output of each converter unit () and the measurements are transmitted (L) to a regulating device () for sharing the supply of the domestic network () according to the available power, each converter unit () comprises an upstream processing stage (E) and a downstream processing stage (E), each including an anti-disturbance device (D, D), linked (B, B) with the primary network () and linked (B, B) with the domestic network (), respectively. The anti-disturbance devices (D, D) are coupled with a set () of domestic level adapters () distributed in the processing stages (E, E), the set of adapters () likewise including a neutral-line separator ().
