Low cost modular architecture for piloting an aerodyne operating with high level of security

A modular architecture for electronic equipment. Data-concentration modules, processing modules and display devices are interconnected by data-transmitters with sensors, measuring instruments and detectors. The data-concentration modules concentrate only the data which is not critical for the industrial process. This data is transmitted to other modules by a multi-receiver serial bus. The other modules directly receive the critical data which is routed by separate, respective serial digital links between, on the one hand, display devices and functions controlling the processes which are distributed in the process modules, and, on the other hand, sensors, measuring instruments and actuators.
