Abstract
A computer implemented method including: receiving a history database file and a public key of a public/private key pair from an external server; generating aircraft maintenance and operations data using one or more onboard sensors that are configured to sense one or more characteristics of aircraft maintenance and operations systems; classifying the generated aircraft maintenance and operations data as selected data and unselected data based on a comparison of the sensed aircraft maintenance and operations data with stored aircraft maintenance and operations data of a trained aircraft data model; storing the selected data in the received history database file; encrypting the received history database file using the received public key of the public/private key pair to generate an encrypted history database file including selected data; transmitting the encrypted history database file including the selected data to an external server.
Core Innovation
The invention deploys an onboard data gateway that stores a context-based data analyzer, a trained aircraft data model, and a cryptographic data synthesizer, and establishes communication with an external server. The data gateway receives a history database file and a public key of a public/private key pair from the external server.
The data gateway generates aircraft maintenance and operations data in real-time using one or more onboard sensors configured to sense one or more characteristics of aircraft maintenance and operations systems. The context-based data analyzer classifies the generated aircraft maintenance and operations data as selected data and unselected data based on a comparison of sensed aircraft maintenance and operations data with recommended ranges of stored aircraft maintenance and operations data of the trained aircraft data model.
The selected data is included in the received history database file, and the data gateway stores the selected data in the received history database file. A cryptographic data synthesizer encrypts the received history database file using the received public key of the public/private key pair to generate an encrypted history database file including the selected data, and the encrypted history database file including the selected data is transmitted to the external server.
Claims Coverage
The document provides two independent claims, which share the same overall inventive workflow and architecture: onboard real-time sensing, context-based classification into selected and unselected data using recommended ranges from a trained aircraft data model, selection storage in a history database file, and encryption of the history database file with a public key followed by transmission to an external server.
Onboard data gateway with context-based classification and cryptographic data synthesis
Deploying a data gateway onboard to establish communication with an external server, wherein the data gateway stores at least a context-based data analyzer, a trained aircraft data model, and a cryptographic data synthesizer; generating aircraft maintenance and operations data using one or more onboard sensors configured to sense one or more characteristics of aircraft maintenance and operations systems in real-time; classifying, by the context-based data analyzer, the generated aircraft maintenance and operations data as selected data and unselected data based on a comparison with recommended ranges of stored aircraft maintenance and operations data of the trained aircraft data model; encrypting, by the cryptographic data synthesizer, the received history database file using the received public key to generate an encrypted history database file including the selected data; and transmitting the encrypted history database file including the selected data to the external server.
System for analyzing aircraft-generated data using a ground simulator-trained data analysis model at a data gateway
A system for analyzing aircraft-generated data for criticality and sensitivity at a data gateway using a ground simulator-trained data analysis model, comprising at least one processing device and a memory storing machine-readable instructions that cause the processing device to deploy data gateway onboard to establish communication with an external server; receive, by the data gateway, a history database file and a public key of a public/private key pair from the external server; generate aircraft maintenance and operations data using one or more onboard sensors configured to sense one or more characteristics of aircraft maintenance and operations systems in real-time; classify, by the context-based data analyzer, the generated aircraft maintenance and operations data as selected data and unselected data based on a comparison with recommended ranges of stored aircraft maintenance and operations data of the trained aircraft data model; store the selected data in the received history database file; encrypt, by the cryptographic data synthesizer, the received history database file using the received public key to generate an encrypted history database file including selected data; and transmit the encrypted history database file including the selected data to the external server.
Across the independent claims, the main inventive contribution is an onboard data gateway workflow that generates aircraft maintenance and operations data from onboard sensors, uses a context-based data analyzer with a trained aircraft data model containing recommended ranges to classify the data as selected versus unselected, stores the selected data in a history database file, encrypts that history database file using a received public key, and transmits the encrypted file to an external server.
