Aircraft Data Link Router for Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft data communication systems face inefficiencies due to duplication of data transmission to multiple on-vehicle systems, leading to negative bandwidth and monetary impacts, and lack of data sharing or synchronization between devices without specific programming.
Innovation Solution
A data link communication system with a router, routing control logic, and conditional logic database that monitors and routes data based on defined datatypes, allowing for flexible and reconfigurable data forwarding without hardware or software updates, enabling efficient data distribution and synchronization among on-vehicle systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual uplink messages are transmitted to each on-aircraft system that needs the information, then each system receives the required data, but bandwidth utilization deteriorates and operational costs increase due to duplication
Solution Approach 1:
The patent merges multiple duplicate uplink message transmissions into a single centralized transmission. The Communications Management Unit receives one uplink message and automatically distributes it to all relevant on-aircraft systems through the aircraft data bus, eliminating redundant transmissions and optimizing bandwidth utilization while ensuring all systems receive the required data
Solution Approach 2:
The Communications Management Unit is designed with multi-functionality to handle various types of uplink messages and distribute them to different on-aircraft systems based on pre-configured routing rules. This universal approach allows a single system to serve multiple data distribution needs without requiring separate dedicated transmission paths for each system
2Reliability
If on-vehicle devices are specifically programmed to share and synchronize data, then data synchronization can occur, but device complexity and programming requirements increase
Solution Approach 1:
The patent introduces the aircraft data bus as an intermediary that facilitates automatic data sharing and synchronization between on-vehicle devices. The Communications Management Unit publishes data to the data bus, and other systems automatically subscribe and receive the data without requiring complex inter-device programming, thus reducing device complexity while enabling reliable data synchronization
Solution Approach 2:
The system implements self-service data distribution where the Communications Management Unit automatically routes uplink messages to relevant systems based on pre-configured rules, and on-aircraft systems automatically receive and process data from the data bus without requiring manual programming or intervention. This self-service mechanism simplifies device complexity while maintaining synchronization reliability

AI summary
Systems and methods for reconfigurable on-vehicle data routing are provided. In one embodiment, a data link communication system comprises: a router to communicate with at least one communication bus and at least one data bus, and monitor data communicated over the communication data buses, wherein the communication bus communicates data link messages with an off-vehicle service provider system, wherein the data bus transports data between the router and a plurality of on-vehicle systems; a routing control logic; and a conditional logic database, wherein the database comprises definitions of one or more datatypes and definitions for at least one data forwarding command; wherein, in response to receiving a first set of data associated with a datatype defined by the database, the logic executes the at least one data forwarding command to control the router to output a second set of data to one or more of the plurality of on-vehicle systems.
