AUTOMATED SECURITY SYSTEM OF AN INDUSTRIAL PLANT

摘要

The invention relates to an automated safety system of an industrial installation comprising a plurality of sensors for taking measurements of an industrial process, a plurality of actuators intended to perform operations that depend on measurement signals delivered by said sensors. at least one first processing line and at least one second processing line connecting the sensors and the actuators. This system is characterized in that the first processing chain comprises at least a first processing unit implementing a first technology while the second processing chain comprises at least a second processing unit implementing a second technology different from the first technology so as to provide a partial redundancy of at least one critical safety function of the industrial plant.
