Tamper-Proof Flight Recorder for Remote Vehicle Command History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing approaches for data recordation in unmanned vehicles are inadequate, often failing to provide a complete operation history, which limits accurate analysis of events and can lead to discrepancies in command transmission and execution.
Innovation Solution
A system and method for recording user operation data and vehicle operation data, including outgoing and incoming commands, along with vehicle status data, using a user operation data recorder and vehicle operation data recorder, which are integrated with the remote controller and vehicle, respectively, to ensure tamper-proof and secure data storage, and analysis of discrepancies to determine the cause of vehicle behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing data recordation approaches are used in unmanned vehicles, then the system complexity is low, but the completeness and accuracy of operation history is insufficient
Solution Approach 1:
The patent divides the recordation system into two separate recorders: a user operation data recorder in the remote controller and a vehicle operation data recorder in the unmanned vehicle. Each recorder captures specific types of data independently, ensuring complete operation history without requiring a single complex centralized system.
Solution Approach 2:
The patent combines data from both recorders to create a complete operation history. By merging user commands with vehicle responses and status data, the system achieves comprehensive recording capability while maintaining relatively simple individual recorder designs.
2Measurement precision
If detailed operation data is recorded for accurate event analysis, then the measurement precision is improved, but the data storage requirements and processing complexity increase
Solution Approach 1:
The patent applies local quality by having different recorders capture different types of data with appropriate detail levels. The user operation data recorder captures command information while the vehicle operation data recorder captures status and response data, optimizing storage usage by recording only relevant information at each location.
3Ease of operation
If the recorded data is made accessible for modification, then the ease of operation is improved, but the reliability and integrity of operation history is compromised
Solution Approach 1:
The patent implements preliminary action by establishing secure, write-protected storage mechanisms in both recorders before data is potentially accessed or analyzed. This ensures data integrity is maintained from the moment of recording, while still allowing authorized reading and analysis of the operation history.
Data Source
AI summary
A device for recording user operation data for a remotely controlled vehicle includes a memory off-board the remotely controlled vehicle and a housing receiving the memory. The memory is configured to record user operation data comprising outgoing operation commands that affect operation of the remotely controlled vehicle. The outgoing operation commands are received via a remote controller of the remotely controlled vehicle and transmitted to the remotely controlled vehicle. The housing is removable from the remote controller and more resistant to destruction than the rest of the remote controller.
