Pre-placed Messages for Unmanned Vehicle Bandwidth Degradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned vehicles, particularly those using the STANAG 4586 communication standard, face challenges with severe bandwidth degradation in wireless links due to environmental factors and jamming, leading to incomplete or delayed control messages, which can result in improper actions.
Innovation Solution
A communication enhancement module that intercepts and modifies messages to utilize pre-placed messages stored in the device, reducing bandwidth requirements by sending a single activation message to activate a set of pre-placed messages, ensuring timely and reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple control messages are sent sequentially over a degraded wireless link, then the overall action can be completed, but the messages may be delayed or lost resulting in incomplete instructions
Solution Approach 1:
The patent pre-loads complete sets of control messages into the unmanned vehicle's memory before transmission is needed. When bandwidth degradation occurs, the controller can immediately transmit a single activation message that triggers playback of the pre-loaded message set, eliminating sequential transmission delays and ensuring complete instructions are delivered without loss or delay.
2Quantity of substance
If a single activation message is sent to trigger pre-placed messages, then bandwidth requirements are reduced, but the system complexity increases
Solution Approach 1:
The system pre-loads complete control message sets into the unmanned vehicle's memory during periods when bandwidth is available. The communication module is enhanced with message storage and activation capabilities, allowing a single activation message to trigger playback of pre-loaded messages, dramatically reducing real-time bandwidth consumption while the added complexity is confined to the communication module.
3Speed
If control messages are transmitted in real-time over degraded bandwidth, then timely communication is attempted, but message completeness cannot be guaranteed
Solution Approach 1:
Complete sets of control messages are pre-loaded into the unmanned vehicle's memory before they are needed. When real-time transmission is attempted over degraded bandwidth, a single activation message triggers the playback of the complete pre-loaded message set, ensuring message completeness is guaranteed while maintaining timely delivery.
Data Source
AI summary
Embodiments for a communication enhancement module for a first communicating device are disclosed. The communication enhancement module includes instructions thereon. The instructions cause the communication enhancement module to receive an activation message from a data terminal of the first communicating device. The activation message is sent from a communication enhancement module of a second communicating device. In response to receiving the activation message, a set of pre-placed messages is identified to which the activation message is assigned. A set of messages is generated corresponding to the set of pre-placed messages. Each message in the set of messages conforms to a communication protocol used by the second communicating device for messages sent to the first communicating device. The set of messages indicate that the set of messages originated at the second communicating device. The set of messages is sent to a main processing module of the first communicating device.
