Abstract
A voter configured for in-flight tuning based on flight phase and operational scenario receives sensor signals and applies adaptive tolerances. The voter allows integration of high-integrity sensors with less accurate, low-integrity sensors, or even sensors that are susceptible to noise, dropouts, interference or sabotage without compromising the voted signal integrity or availability. The voter composites low-integrity sensor signals to produce a quasi-high-integrity sensor signal suitable for inclusion in a golden signal and provides sensor fusion.
Claims20
A computer apparatus comprising:
- at least one processor in data communication with a memory storing processor executable code for configuring the at least one processor to:
- receive a plurality of sensor signals;
- perform failure scenario analysis in real-time to determine a combination of failures that would affect signal integrity and availability for specific operational scenario;
- apply a set of operational scenario specific tolerances to the plurality of sensor signals, each of the sensor tolerances corresponding to at least one of a monitor threshold, a fault detection time, signal correction amount, signal correction rate, a signal equalization amount, a signal equalization rate, a signal centering amount, and a signal centering rate;
- apply a voting algorithm to the plurality of sensor signals;
- and
- identify one or more of the plurality of sensor signals outside the set of operational scenario tolerances.
