Edge computing based airplane auxiliary power unit health monitoring system

Abstract:

A processor implemented method in an aircraft-mounted edge computing device configured for real-time monitoring and analysis of APU health information onboard an aircraft is provided. The method comprises: receiving raw APU data from an electronic control unit associated with an APU; downloading one or more tuning parameters from a cloud-based health monitoring system, wherein the one or more tuning parameters includes a threshold level that is adjustable by the cloud-based health monitoring system based on analyzed APU health information; analyzing the raw APU data using the one or more tuning parameters to capture elements of the raw APU data that indicate an APU health concern; reducing the amount of raw APU data in the captured elements by removing raw APU data indicating intermittent or false-positive APU health concerns; and transmitting the captured elements indicating an APU heath concern using an Internet of things protocol to the cloud-based health monitoring system.
