Patent ID: 7631113

Claim:
A control system for a railway system rendered secure through diversification comprising: at least two processors processing commands for the railway system, the processors arranged in parallel to receive identical input data on a corresponding input, each processor receiving a first and second set of instructions, each processor calculates and delivers identical output data at different outputs with respect to the identical input data, the first set of instructions being different than the second set of instructions, a command selection component including at least two inputs and a command output, each input connected to an output of a processor, the command output delivering a command signal selected from the processor output data, based on predetermined criterion, the first and second set of instructions corresponding to each processor running at least two modular application automatic systems, the modular application automatic systems being identical for the first and second sets of instructions, the first and second sets of instructions corresponding to each processor being specific to creating a subsequent activation sequencer for the modular application automatic systems in an associated sequence, each sequencer differing from other sequencers by the specific associated sequence.
