Real-Time Data Acquisition System for Mobile Assets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data acquisition and recording systems in high-value mobile assets require physical access and proprietary software for data extraction and analysis after an incident, which is inefficient and delays investigation and analysis.
Innovation Solution
A real-time data acquisition and recording system that uses 360-degree cameras, microphones, and a multimedia management system to encode and store data, allowing for real-time or near real-time access and streaming of event, operational, video, and audio data to remote users via a web server, eliminating the need for physical access and proprietary software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical access and proprietary software are used for data extraction, then data security and system integrity are maintained, but data access time and operational efficiency deteriorate
Solution Approach 1:
The patent creates a copy of the recorded data from the black box system and transmits it to a remote server, allowing investigators to access the copied data remotely without needing physical access to the original system. This resolves the contradiction by maintaining the integrity of the original stored data while enabling fast remote access to copies.
Solution Approach 2:
The patent introduces a communication module and remote server as intermediaries between the black box system and investigators. The communication module extracts and transmits data, while the remote server stores and provides access to the data, eliminating the need for direct physical access to the black box while maintaining data security through controlled access protocols.
2Productivity
If real-time data transmission is implemented, then operational efficiency and response time improve, but system complexity and data transmission requirements increase
Solution Approach 1:
The patent extracts the data transmission function from the core black box recording system by adding a separate communication module. This module handles all real-time data extraction and transmission tasks, allowing the main recording system to remain simple while the communication handling is separated and managed independently.
3Ease of operation
If remote access capability is added, then ease of operation and investigation speed improve, but device complexity and power consumption increase
Solution Approach 1:
The communication module is designed to perform multiple functions: it can extract data from the black box, transmit data to remote servers, receive commands from remote users, and manage data formatting. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in overall device complexity while providing comprehensive remote access capabilities.
Data Source
AI summary
A data acquisition and recording system (DARS) and viewer for mobile assets that includes a data encoder, onboard data manager, and at least one local memory module. DARS processes video data from at least one 360 degree camera and stores a compressed record of the data at least once per second in the local memory module. DARS is designed to run in near real-time mode, storing a full record comprising five minutes of data to a remote memory module every five minutes, and in real-time mode, streaming video data to the remote memory module by uploading a record of data at least once per second and up to once every tenth of a second. Remotely located users can view video, audio, and data in various view modes through a web browser or virtual reality device, which provides for quicker emergency response, validate the effectiveness of repairs and rerouting, and monitor crew performance and safety.
