Wireless Communication Unit for Aerial Engine Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently transferring engine data from aerial vehicles to ground systems, particularly due to the difficulty in accessing and utilizing data stored on electronic engine controllers (EECs) within the vehicles.
Innovation Solution
A wireless communication unit (WCU) is integrated with aerial vehicles, capable of accessing transmission parameters such as airport location and available networks, selecting an optimal wireless network, and transmitting engine data to a ground system via that network, using interfaces like TIA-485 or ARINC 664, and communicating with a portable maintenance access terminal for maintenance purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual data retrieval is used to access engine data from EECs, then data can be obtained, but the process is difficult and time-consuming
Solution Approach 1:
The wireless communication unit automatically performs data transfer operations without requiring manual intervention. The system self-manages network selection, connection establishment, and data transmission to the ground system, eliminating the need for manual data retrieval processes
Solution Approach 2:
The patent replaces manual mechanical data retrieval processes with automated electronic wireless communication. The wireless communication unit uses electronic interfaces (TIA-485, ARINC 664) and wireless networks to transfer data automatically, substituting the manual mechanical approach with an automated electronic system
2Loss of information
If automated wireless data transfer is implemented, then data availability at ground system increases, but device complexity increases due to wireless network selection requirements
Solution Approach 1:
The wireless communication unit acts as an intermediary device between the EEC and the ground system. It manages the complexity of wireless network selection, connection establishment, and data transmission protocols, shielding the ground system from these complexities while ensuring reliable data transfer
Solution Approach 2:
The wireless communication unit is designed with multi-functionality to handle various wireless network protocols and selection criteria. It can automatically evaluate multiple networks, select the optimal one, and manage communications across different interfaces (TIA-485, ARINC 664, wireless), consolidating multiple functions into a single device
