Method for determining a reliability parameter of a responsive system, and a corresponding signal processing system

摘要

A method and a responsive system for signal processing, particularly a system of the safety instrumentation and control of a nuclear power plant. A first database stores the association of the data processing units, data transmission units, and computer programs of the system, as well as a sequence of steps in the automatic signal processing in accordance with an integral processing specification. A second database stores in memory operating parameters and at least one reliability parameter of each data processing unit and each data transmission unit. The contents of the databases are utilized in a reliability module, which determines the reliability characteristic of the responsive system from the data of the first database and the second database. If and when the reliability parameters change, a transmission takes place to the reliability module, so that in each case an updated reliability parameter may be determined. As a result, the currently valid availability of the responsive system can be learned at any point in time, taking into account the high degree of detailing of the system.
