Etude et implémentation d'un système de contrôle en temps réel d'un procédé industriel via une architecture client/serveur

Abstract

The use of real-time data processing in the implementation of automated systems took a considerable rise in the industrial world. The correct operation of such system does not depend only on a correct logic of calculations, but also of instants when these results are produced. In this work, we propose a real-time control model of an industrial process based on client/server architecture. The server is implemented under the real-time operating system RTLinux. The role of this OS is to control our process by respecting its specific time constraints. The client in our model is equipped with functionalities necessary to observe and act on the distant process. The two units, client and server, are connected through a point-to-point network, using the programming interface socket TCP/IP. A concrete application of this model is implemented. It is a control system of an irradiation device for silicon doping by neutron transmutation in a nuclear reactor. This control takes into account all aspects related to irradiation conditions in order to meet requirements needed by this technique of doping.
