Cooperative Driving Recorder Video Collection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving recorders require manual effort to locate specific video files for accident evidence, are prone to file corruption, and lack coverage for side or rear collisions due to single recorder setups.
Innovation Solution
A system of multiple driving recorders with communication units, image capturing units, and processors connected to a video file server, enabling cooperative video data collection and encryption, with a database for registration and management of devices, facilitating efficient video file sharing and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single driving recorder is mounted on a vehicle to record front view, then the device complexity is low, but the coverage of video evidence is insufficient for lateral or rear collisions
Solution Approach 1:
The patent combines multiple driving recorders mounted on different vehicles into a cooperative system where they share video data through wireless communication. This merging approach allows a single vehicle accident to be captured by multiple recorders from different vehicles, providing comprehensive coverage without requiring multiple recorders on each individual vehicle.
Solution Approach 2:
The driving recorder system is designed to serve multiple functions: it records video for the host vehicle, detects accidents, broadcasts accident information wirelessly, and receives video data from other recorders. This multi-functionality allows a single recorder to provide comprehensive accident evidence coverage without requiring additional dedicated devices.
2Reliability
If numerous video files are stored in the memory card to ensure complete recording, then the reliability of video evidence is improved, but the time and effort required to manually search for specific accident files increases
Solution Approach 1:
The system implements automatic feedback mechanisms where the driving recorder continuously monitors for accident conditions (through sensors detecting sudden deceleration, airbag deployment, etc.), automatically identifies accident-related video segments, and triggers wireless transmission of relevant video data to authorities or cloud storage, eliminating manual search processes.
Solution Approach 2:
The driving recorder system performs self-service by automatically detecting accidents through integrated sensors, autonomously identifying relevant video footage, and initiating transmission of accident evidence without requiring user intervention. This automation significantly reduces the time and effort needed to locate and submit specific accident video files.
3Reliability
If video files are transmitted and stored across multiple devices and servers, then the risk of file corruption is reduced, but the complexity of data management and communication increases
Solution Approach 1:
The patent segments video data into multiple separate files recorded by different driving recorders, each stored independently in different devices. This segmentation ensures that if one file or device fails, other segments remain intact and can be reassembled to reconstruct complete accident evidence, thereby reducing the impact of single-point failures.
4Adaptability or versatility
If multiple driving recorders cooperatively collect and share video data, then the comprehensive coverage of accidents is improved, but the communication and coordination overhead increases
Solution Approach 1:
The system introduces a cloud server or authority server as an intermediary that coordinates communication between multiple driving recorders. The server receives video data from various recorders, manages storage, and handles data retrieval requests, thereby simplifying the communication architecture and reducing direct coordination overhead between individual recorders while maintaining comprehensive data collection capabilities.
Data Source
AI summary
A method for cooperatively collecting video data from driving recorders includes steps of: by a driving recorder serving as a requesting device, broadcasting a video request; by another driving recorder serving as a cooperative device, generating a video file in response to receipt of the video request, encrypting the video file to result in an encrypted file, and transmitting the encrypted file to a video file server; by the video file server, decrypting the encrypted file to result in the video file, storing the video file, and sending a success notification of video data collection to a user device based on contact information contained in pre-stored registration data.
