Real-time Data Streaming for Mobile Asset Incident Investigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data acquisition and recording systems in high-value mobile assets require physical access and manual download of data after incidents, making real-time data access and sharing challenging, especially when the system is unavailable or damaged.
Innovation Solution
A real-time data acquisition and recording system that streams data to a remote repository prior to, during, and after incidents, enabling real-time or near-real-time access via a web browser, using 360-degree cameras and video analytics for incident investigation and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored only on onboard data acquisition and recording systems, then data security and integrity are maintained, but real-time data access and sharing are impossible when the system is unavailable or damaged
Solution Approach 1:
The system performs preliminary actions by continuously streaming data from the onboard data acquisition system to a remote repository before incidents occur. This advance preparation ensures that data is already available in the cloud when needed, eliminating the need for physical recovery of the onboard system and enabling immediate access during incident investigations.
Solution Approach 2:
A remote repository acts as an intermediary between the onboard data acquisition system and investigators. The repository receives, stores, and manages data streams, providing a reliable intermediate storage location that ensures data availability even when the original onboard system is unavailable or damaged.
2Reliability
If physical access to the data acquisition system is required for data extraction, then data security is maintained, but rapid data access during incidents is prevented
Solution Approach 1:
The system creates and maintains a copy of the onboard data acquisition system's data in a remote repository. This copy can be accessed immediately during incidents without requiring physical access to the original system, while security is maintained through controlled access protocols to the remote repository.
Solution Approach 2:
The system replaces the mechanical process of physically accessing and extracting data from onboard systems with an electronic/digital process. Data is transmitted electronically to a remote repository and can be retrieved through digital means, eliminating the need for physical system access while maintaining security through electronic access controls.
3Loss of time
If data is transmitted in real-time to a remote repository, then immediate data access is enabled, but network dependency and data transmission vulnerabilities are introduced
Solution Approach 1:
The system prepares for potential network failures by implementing beforehand cushioning measures. Data is continuously streamed to the remote repository during normal operation, building up a buffer of available data. This ensures that even if network connectivity is lost or the system becomes unavailable, data that has already been transmitted remains accessible in the repository.

AI summary
The real-time data acquisition and recording data sharing system works in conjunction with a real-time data acquisition and recording system and a viewer which provides real-time, or near real-time, access to a wide range of data, such as event and operational data, video data, and audio data to remotely located users such as asset owners, operators and investigators. The data sharing system allows the user to share data obtained from the data acquisition and recording system to remotely located users. The user can share data with remote recipient end users that have internet access and a modern web browser in a secure, controlled, tracked, and audited way. The user, instead of sharing files, shares a URL to the data. URL based data sharing enables the user to control, track, and audit sensitive data.
