Method and architecture for critical systems utilizing multi-centric orthogonal topology and pervasive rules-driven data and control encoding
The present disclosure relates to novel and advantageous systems and methods of processing and managing data in critical or large-scale systems, such as airliner, automobile, space station, power plant, and healthcare systems. Particularly, the present disclosure relates to a rules-driven data and control method mapped onto complementary physical architecture for a more reliable operational system. By maintaining an algebraic encoding of control and application data at fine granularities, whether static or in transit, it is possible to detect, isolate, and correct many errors that would otherwise go undetected. This more dynamic and precise method addresses cases where deteriorating conditions or cataclysmic events affect much of the system simultaneously, including the control system itself.
1. A system comprising:
two control centers communicably coupled over a network; and
at least one sub-network arranged orthogonal to the network, the sub-network communicably coupling each of the control centers to each of:
a sensor receiving sensed data; and
a controller controlling one or more operations based on the sensed data;
wherein the sensor and controller are communicably coupled together over the at least one orthogonal sub-network; and
an archive storing as non-transitory computer readable media:
a configuration table storing configuration data for each of the control centers, sensor, controller, and archive, wherein the configuration data includes a preferred error correction code, and at least one preferred error correction procedure; and
a real-time time log of events storing actions performed by the control centers, sensor, controller, and archive.
