Process and apparatus for control and monitoring of installation by transmission of information and of commands by optical means

Inventors: Meyer, Jacques; Bouchet, Jean M.; Lande, Jean P.;
Assignee: Framatome (Courbevoie, FR)

The industrial installation comprises an active zone (III) with which there are associated means for measurement and for command and a control position (I) separated from the active zone. Means for measurement, for control and for command (15) located in the active zone are supplied with luminous radiations, from the control position, through an optical fibre (8) joining the active zone to the control position. Radiation having a broad spectral band is emitted in the fiber (8) from the control position (I) and then divided in order to obtain unitary radiations for supplying each of the means (15). The invention applies to nuclear reactors. |

DETAILED DESCRIPTION The object of the invention is thus to propose a process for the control and for the supervision of an industrial installation by transmission of information and of orders by optical means, the industrial installation comprising an active part with which means for measurement, for control and for command are associated and a control and supervision position separated by a large distance, from the zone in which the active part is situated, at least one optical fiber providing for the transmission of the information and of the orders between the active part of the installation and the control position.
The process permits the derivation of maximum benefit from the advantages of an optical transmission, with the avoidance of any presence of sources of electric current within the active part of the installation, and with the provision of a perfectly identified optical radiation associated with each one of the means for measurement, for control or for command.
In order to achieve this object, the means for measurement, for control and for command situated in the active part of the installation are supplied with unitary luminous radiations, from the supervision position and through the optical fiber, by directing in this optical fiber, from the supervision position, a luminous radiation having a broad spectral band and by dividing this luminous radiation in order to obtain unitary radiations for supplying each of the means for measurement, control and command with a luminous radiation.
The invention likewise relates to a device for control and for supervision of an industrial installation permitting the transmission of information and of orders by optical means.
