Abstract

Abstract Translated from French L'installation industrielle comporte une zone active (III) à laquelle sont associés des moyens de mesure et de commande et un poste de conduite (I) séparé de la zone active. On alimente en rayonnements lumineux des moyens de mesure, de contrôle et de commande (15) situés dans la zone active, depuis le poste de conduite, grâce à une fibre optique (8) joignant la zone active au poste de conduite. Un rayonnement à large bande spectrale est envoyé dans la fibre (8) depuis le poste de conduite (1) puis fractionné en rayonnements unitaires pour alimenter chacun des moyens (15). L'invention s'applique à de nombreuses installations industrielles et en particulier aux réacteurs nucléaires. The industrial installation comprises an active zone (III) with which are associated measuring and control means and an operator's station (I) separated from the active zone. Light radiation is supplied to measurement, control and command means (15) located in the active zone, from the driving position, by means of an optical fiber (8) joining the active zone to the driving position. Radiation with a wide spectral band is sent into the fiber (8) from the driving position (1) then split into unitary radiations to supply each of the means (15). The invention applies to numerous industrial installations and in particular to nuclear reactors.
