Automated Fault Data Transfer via Dynamic Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for transferring mobile platform metrics and fault data from electronic logbooks to ground-based systems are inefficient, labor-intensive, and prone to delays, especially due to varying communication connectivity options, which can inhibit timely maintenance and affect operational schedules.
Innovation Solution
A system and method for establishing a communication link between an onboard computer system (OCS) and a central computer system (CCS) using a communications management function (CMF) that configures data into a transmittable file and automatically selects suitable communication channels, establishing a secure link for data transfer using any available protocol, such as GPRS, VHF, or satellite networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual data entry from paper logbooks is used, then data transfer is simple, but the process is labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical data entry processes with an automated electronic system. The electronic logbook directly interfaces with the ground-based computer system through communication protocols, eliminating the need for manual copying and keying of data, thereby increasing productivity while managing system complexity through standardized electronic interfaces
Solution Approach 2:
The system enables self-service data transfer where the electronic logbook automatically initiates and completes data transmission to the ground-based system without requiring manual intervention. The automated interface handles data extraction, formatting, and transmission, allowing the system to serve itself rather than requiring labor-intensive manual processes
2Loss of time
If electronic logbooks are used, then data recording efficiency is improved, but data transfer still requires removal from mobile platform causing delays
Solution Approach 1:
The patent implements dynamic data transfer capabilities where the electronic logbook can communicate with ground-based systems in real-time or near-real-time while remaining on the mobile platform. The system adapts its communication method based on availability, allowing data to be transmitted whenever connectivity is established, thereby reducing time loss without restricting operational flexibility
Solution Approach 2:
The system introduces communication protocols and interfaces as intermediaries between the electronic logbook and ground-based systems. These intermediaries enable data transfer without requiring physical removal of the logbook, allowing seamless communication through wireless or wired connections while the logbook remains on the mobile platform
3Productivity
If automated data transfer is implemented, then productivity is improved, but communication connectivity issues arise
Solution Approach 1:
The system performs preliminary actions by pre-configuring communication parameters, protocols, and data formats before transfer is needed. The electronic logbook is pre-programmed with communication capabilities and data formatting rules, so when connectivity is available, data can be immediately transferred without delays for setup or configuration, thereby maintaining high productivity while preparing for potential connectivity issues

AI summary
A system and method are provided for establishing a communication link between an on onboard computer system (OCS) of a mobile platform and a central computer system (CCS) located remotely from the mobile platform. A message containing data to be downloaded from the OCS to the CCS is sent from a first portion of an electronic log book function (ELB1) of the OCS to a second portion of a communications management function (CMF2) of the OCS. The message is configured into a transmittable data file and placed into an outgoing queue of the CMF2. The CMF2 automatically selects at least one desired communication channel from a plurality of available communication channels utilizing a configuration file of the CMF2. The CMF2 establishes a secure link between the OCS and the CCS utilizing the automatically selected communication channel and sends the transmittable data file to the CCS, via the secure established link over the automatically selected channel.
