METHOD AND PROCESS CONTROL SYSTEM FOR CONTROLLING, MONITORING AND REGULATING IN PARTICULAR COMPLEX INDUSTRIAL PROCESSES, SUCH AS FOR EXAMPLE IN A NUCLEAR POWER STATION
Complex industrial processes are involved for example in the operation of a nuclear power station, in particular in emergency situations. A digital computer which implements by means of its program so-called automatic agents which interact with sensors or regulators is a prerequisite. Process information is obtained or the process is influenced by the activities of the automatic agents (programmable controllers) and operators, progress in carrying out activities being marked by actions. In detail: a) information supplied by the programmable controllers and operators is collected in a protocol of the computer (both the history of plant behaviour and that of actions are acquired in the protocol); b) a number of specifications of activities contain process descriptions which describe which actions in which types of situations (situation types) can be triggered when carrying out the activity concerned; c) a comparator unit compares the situation types with the real situation indicated by the protocol and ascertains whether the given situation corresponds to a situation type from which action possibilities are derived; d) each specification of an activity contains a number of references to information for carrying out the activities (implementation information), aimed at the programmable controllers or operators. A process control system for implementing such a method is disclosed.
