Remote Video Analytics for Mobile Asset Incident Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data acquisition and recording systems in high value mobile assets, such as locomotives and aircraft, often require physical access to retrieve data after an incident, which can be impractical or impossible in certain situations.
Innovation Solution
A real-time data acquisition and recording system (DARS) that streams data, including video, audio, and operational data, to a remote data repository prior to, during, and after an incident, allowing for real-time or near real-time access and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored locally in onboard recorders, then data security and integrity are maintained, but real-time remote access is lost
Solution Approach 1:
The system performs preliminary actions by continuously streaming and storing data in both local onboard recorders and remote cloud repositories simultaneously before any incident occurs. This dual-storage approach ensures that data is already available in remote locations, eliminating retrieval delays while maintaining data integrity through redundant storage.
Solution Approach 2:
The patent introduces a communication module as an intermediary that continuously transmits data from the onboard recorder to remote servers via cellular, satellite, or other wireless networks. This intermediary channel enables real-time remote access to data without requiring physical access to the vehicle or device.
2Reliability
If physical access to data recorder is required, then data authentication is ensured, but incident investigation efficiency decreases
Solution Approach 1:
The system performs preliminary authentication and validation of data during the streaming process, digitally signing data packets and verifying integrity before transmission. This preliminary authentication ensures that remotely accessed data is verified and trustworthy, eliminating the need for physical verification while maintaining security.
Solution Approach 2:
The patent creates authenticated copies of the original data and stores them in remote repositories. These copies contain digital signatures and verification data that authenticate their origin, allowing investigators to access verified data remotely without needing to physically access the original recorder.
3Loss of time
If data streaming is implemented, then real-time access is achieved, but network dependency increases
Solution Approach 1:
The system implements local quality by maintaining different data storage characteristics in different locations: the onboard recorder provides secure, authenticated local storage with crash-survivable memory, while remote servers provide accessible cloud storage. Each location has optimized properties for its specific function, and the system adapts to network availability by relying on local storage when networks are unavailable.

AI summary
A video content analysis system for mobile assets that includes track detection and infrastructure monitoring component. The track detection and infrastructure monitoring includes a reinforcement learning component, an object detection and location component, and an obstruction detection component to analyze video data, audio data, vehicle data, weather data, and route/manifest data to determine internal and/or external conditions relating to an the asset. A data acquisition and recording system uploads the data, internal and/or external condition information, object detection information, object location information, and obstruction detection information to a remote memory module and provides streaming video data in real-time to a remotely located user. Remotely located users can view the data in various view modes through a web browser or virtual reality device, which provides for quicker emergency response, validates the effectiveness of repairs and rerouting, and monitors crew performance and safety.
