Vehicle Video Recorder Backup via Impact-Triggered User Terminal Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle video record systems face challenges in accessing accident videos when the system is damaged or data is lost due to fires, making it difficult to identify the cause of accidents.
Innovation Solution
A video record system equipped with an impact sensor, camera module, memory, and controller that determines significant impacts, attempts communication to a user terminal, and transmits video data using a capacitor-powered connection to ensure data transfer even in power failures or system damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the video record system is built into the vehicle before release, then the system is integrated and stable, but the recorded video data may be lost due to fire or power system damage
Solution Approach 1:
The patent introduces a communication module as an intermediary between the video record system and external devices. When an impact is detected by the impact sensor, the communication module automatically transmits the recorded video data to an external device (smartphone, tablet, or server), creating a backup copy that is safe from fire damage in the vehicle. This mediator enables data evacuation without requiring manual intervention.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring impact levels and preparing video data for transmission. The impact sensor is always active, and when a threshold is exceeded, the system proactively initiates the data transmission process before the fire can destroy the evidence. This preliminary detection and preparation ensures data is saved in advance of the catastrophic event.
2Loss of information
If the system attempts to transmit video data after an accident, then data can be saved externally, but power supply problems may prevent transmission
Solution Approach 1:
The patent incorporates a capacitor as an emergency power source that is charged in advance during normal operation. When an accident occurs and the main power supply fails, the pre-charged capacitor provides the necessary energy to power the communication module and transmit the video data. This beforehand cushioning ensures that power availability is not a barrier to data transmission during critical moments.
3Loss of time
If automatic transmission is enabled, then data is saved quickly, but user consent cannot be obtained
Solution Approach 1:
The patent implements a dynamic transmission strategy where the system adapts its behavior based on the situation. In normal operation, the system operates in automatic mode, immediately transmitting data when impact is detected, without requiring user consent. This dynamic adjustment prioritizes speed and ensures data is saved even if the user is incapacitated. The system flexibly switches between automatic and manual modes depending on the urgency of the situation.
Data Source
AI summary
A video record system, a method of controlling the video record system, and a user terminal may be implemented in a vehicle. The method of controlling the video record system includes: an impact sensor or a microphone; a camera module; a first memory that stores a video transmitted from the camera module; and a controller including a second memory that stores a computer program for controlling storage of the video, and a processor that executes the computer program, such that by executing the computer program, the processor may determine whether an impact is equal to or greater than a set value based on a signal obtained by the impact sensor or the microphone and attempt to be connected to a user terminal and transmit the video to the user terminal when it is determined that the impact is equal to or greater than the set value.
