Kabinendruckkontrollsystem und Verfahren zum Ausführen von Hochgeschwindigkeitsabtasten und Mittelwertbilden zum Berechnen von Druckänderungen

摘要

An aircraft cabin pressure control system (100) and the method implement a technique that oversamples and filters a sensed cabin pressure signal, and then differentiates the oversampled and filtered pressure signal to generate cabin pressure rate-of-change. The oversampling and filtering technique removes circuit and sensor induced noise from the cabin pressure signal, and results in cabin pressure rate-of-change values with less noise than currently known systems and methods.
