Aircraft BITE Data Retrieval Through Voice Command and Audio Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analyzing and decoding Built-in Test Equipment (BITE) data for aircraft maintenance is time-consuming due to binary and hexadecimal formats, requiring manual effort from maintenance personnel.
Innovation Solution
A voice processing system that translates spoken commands into executable commands to retrieve BITE data, allowing maintenance personnel to use voice commands in their native language to fetch and display or audibly receive failure information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If maintenance personnel manually decode and analyze BITE data in binary and hexadecimal format, then they can obtain failure information, but the process takes a lot of time and effort
Solution Approach 1:
The patent replaces the manual mechanical decoding process with an automated voice recognition and natural language processing system. The system converts spoken commands into executable search queries that automatically retrieve and decode BITE data, eliminating the time-consuming manual decoding of binary and hexadecimal formats while maintaining accurate failure data extraction
Solution Approach 2:
The patent introduces a voice processing system as an intermediary between the maintenance personnel and the BITE data storage system. This intermediary automatically translates voice commands into database search queries, retrieves the requested failure information, and presents it in a readable format, thereby eliminating the need for personnel to manually decode binary data
2Ease of operation
If maintenance personnel read data from a particular memory location in NVM, then they can access BITE failure data, but the process requires significant manual effort
Solution Approach 1:
The patent replaces the manual process of navigating to specific memory locations with an automated voice-command-driven system. The voice processing system automatically translates natural language requests into the appropriate memory access commands and data retrieval operations, eliminating the need for personnel to manually locate and read data from specific NVM addresses
Solution Approach 2:
The system enables self-service data retrieval where the maintenance personnel simply speak their information need, and the system autonomously performs the entire data access process including locating the memory address, reading the data, decoding it, and presenting the results without requiring manual intervention at each step
Data Source
AI summary
A voice processing system for obtaining data from built-in test equipment of an aircraft which includes an audio device adapted and configured to receive spoken instruction of a user, a voice processor adapted and configured to process the audio input and to translate the audio input into command terms and a memory having a command database programmed with command terms. The memory is adapted and configured to receive translated command terms from audio input, search the command database for translated command terms, map the translated command terms to programmed command terms, and output a command message for retrieval. The system also includes a command processor adapted and configured to receive the command message from the memory and to perform the command by searching stored built-in test equipment failure data in accordance with the command message.
