Open-loop and closed-loop control unit
First Claim
1. An open-loop and closed-loop control unit for a safety-relevant apparatus, comprising:
- a computer unit having a number of computer inputs and computer outputs;
signal input lines;
a decision making unit; and
a circuit unit having a number of circuit inputs and circuit outputs, said circuit unit having hardware components for simulating some logic operations being carried out in said computer unit, said circuit inputs and said computer inputs corresponding to one another with respect to the logic operations being connected in parallel to a respective one of said signal input lines, said computer outputs and said circuit outputs corresponding to one another with respect to the logic operations are each connected to said decision-making unit;
said decision-making unit outputting an output signal for open-loop control of the safety-relevant apparatus in dependence on a correspondence between signals from said computer outputs and from said circuit outputs.

Abstract
An open-loop and closed-loop control unit for a safety-relevant apparatus, in particular for aviation applications, has a computer unit with a number of computer inputs and computer outputs, and a circuit unit with a number of circuit inputs and circuit outputs. The circuit unit has hardware components for simulating some of the logic operations that can be carried out in the computer unit. The circuit inputs and computer inputs that correspond to one another with respect to the simulated logic operations are each connected in parallel to a signal input line. The computer outputs and circuit outputs which correspond to one another with respect to the simulated logic operations are each connected to a decision-making unit, by which an output signal for open-loop control of the safety-relevant apparatus can be emitted as a function of the correspondence between the signals from the computer output and from the circuit output.
