Abstract
A decentralized trust assessment system, comprising a neural network, a trust module, and a local subsystem, wherein the trust module controls whether a plurality of inputs to the local subsystem are trustworthy. The decentralized trust assessment system provides rotorcraft and tiltrotor aircraft with airborne systems able to detect bad and spoofed data from a wide variety of data streams.
Claims20
A decentralized trust assessment system, comprising:
- a data bus comprising at least one bus channel;
- a flight control computer configured to receive information from the data bus;
- a neural network;
- a trust module;
- and
- a local subsystem;
- wherein the trust module controls whether a plurality of inputs to the local subsystem are trustworthy as a function of at least one of (1) detecting a failure of the at least one bus channel, (2) detecting that the at least one bus channel is providing data outside a predetermined max window, and (3) identifying an occurrence of an odd-numbered bus channel cycling between a minimum value and maximum value.
4 more elements
A method of decentralizing trust assessments, comprising:
- training a neural network to create a trained neural network;
- programming a trust module to review a data stream for a condition;
- reviewing the data stream with the trust module for the condition;
- and
- analyzing the data stream for a pattern with the trained neural network
- wherein the condition comprises at least one of (1) detecting a failure of a bus channel in communication with a flight control computer, (2) detecting that the bus channel is providing data outside a predetermined max window, and (3) identifying an occurrence of an odd-numbered bus channel cycling between a minimum value and maximum value.
3 more elements
A decentralized trust assessment system of an aircraft, comprising:
- a data bus comprising at least one bus channel;
- a flight control computer configured to receive information from the data bus;
- at least one input data stream from the flight control computer;
- a local subsystem in the aircraft, the local subsystem configured to act upon the at least one input data stream;
- a trained neural network;
- and
- a trust module configured to analyze the at least one input data stream;
- wherein the trust module controls whether the at least one input data stream to the local subsystem is acted upon by the local subsystem;
- and
- wherein the trust module makes the determination as a function of data of the input data stream as a function of at least one of (1) detecting a failure of the at least one bus channel, (2) detecting that the at least one bus channel is providing data outside a predetermined max window, and (3) identifying an occurrence of an odd-numbered bus channel cycling between a minimum value and maximum value.
