Internet connected auxiliary power unit airline maintenance system

A computer-implemented system for generating maintenance recommendation for an auxiliary power unit (APU), the computer-implemented system comprising:

• a memory having processor-readable instructions stored therein;
• and
• at least one processor configured to access the memory and execute the processor-readable instructions, which when executed by the processor configures the processor to perform functions for:
• transmitting digitized APU data to an edge node;
• transmitting one or more tuning parameters from a computer-implemented cloud-based health monitoring system to the edge node, the one or more tuning parameters including a threshold level that is adjustable by the computer-implemented cloud-based health monitoring system based on the digitized APU data;
• applying, at the edge node, an algorithm that analyzes the digitized APU data using the one or more tuning parameters to capture only elements of the digitized APU data that indicate an APU health concern, wherein the algorithm is configured to remove digitized APU data indicating intermittent or false-positive APU health concerns, resulting in reduced time to capture and evaluate APU data;
• storing the digitized APU data that indicate the APU health concern in a buffer;
• applying a clustering technique including a support vector machine to the APU data in the buffer to distinguish a true APU health concern from intermittent or false-positive APU health concerns, wherein a stop timer is used to end the application of the clustering technique after a pre-determined time period has elapsed;
• and
• transmitting the captured elements indicating the true APU health concern to the computer-implemented cloud-based health monitoring system.

A non-transitory computer-readable medium containing instructions for generating maintenance recommendation for an auxiliary power unit (APU), the non-transitory computer-readable medium storing instruction that, when executed by at least one processor, configure the at least one processor to perform:

• transmitting, by one or more processors, digitized APU data to an edge node;
• transmitting, by the one or more processors, one or more tuning parameters from a computer-implemented cloud-based health monitoring system to the edge node, the one or more tuning parameters including a threshold level that is adjustable by the computer-implemented cloud-based health monitoring system based on the digitized APU data;
• applying, by the one or more processors at the edge node, an algorithm that analyzes the digitized APU data using the one or more tuning parameters to capture only elements of the digitized APU data that indicate an APU health concern, wherein the algorithm is configured to remove digitized APU data indicating intermittent or false-positive APU health concerns, resulting in reduced time to capture and evaluate APU data;
• storing, by the one or more processors, the digitized APU data that indicate the APU health concern in a buffer;
• applying, by the one or more processors, a clustering technique including a support vector machine to the APU data in the buffer to distinguish a true APU health concern from intermittent or false-positive APU health concerns, wherein a stop timer is used to end the application of the clustering technique after a pre-determined time period has elapsed;
• and
• transmitting, by the one or more processors, the captured elements indicating the true APU health concern to the computer-implemented cloud-based health monitoring system.
