Abstract
(EN)
[Problem] To provide a novel optical network which can be used as an in-vehicle optical backbone network and exhibits high capacity, low delay, low power consumption, low noise and low cost. [Solution] An optical network system, wherein: a signal processing unit 13 controls a light source 11, and generates an optical signal which includes an information portion to be read by one of the gateway units 5a, and a continuous light portion to be written thereby; a network control unit 15 generates an electrical signal which designates a gateway unit 5a and pertains to whether the information incorporated into the optical signal is to be read or written; and when designated by the electrical signal, each of the gateway units 5a transfers information to and from an electronic control unit 7, and reads information included in the corresponding optical signal or writes information in the continuous light portion, on the basis of the information included in the electrical signal about whether to read or write information.

La présente invention vise à proposer un nouveau réseau optique qui puisse être utilisé en tant que réseau de base optique à bord d'un véhicule et qui présente une capacité élevée, un faible retard, une faible consommation d'énergie, un faible bruit et un faible coût. À cet effet, l'invention concerne un système de réseau optique, dans lequel : une unité de traitement de signaux (13) commande une source lumineuse (11) et génère un signal optique qui comprend une partie informations devant être lue par une des unités passerelle (5a), et une partie lumière continue devant donc être écrite ; une unité de commande de réseau génère (15) un signal électrique qui désigne une unité passerelle (5a) et sert à déterminer si les informations incorporées dans le signal optique doivent être lues ou écrites ; lorsqu'elle est désignée par le signal électrique, chacune des unités passerelle (5a) transfère les informations vers et à partir d'une unité de commande électronique (7), et lit les informations contenues dans le signal optique concerné ou écrit les informations dans la partie lumière continue, sur la base des informations contenues dans le signal électrique et indiquant si les informations contenues dans le signal électrique doivent être lues ou écrites.
