Vehicle Video Storage Switching Under High Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems for vehicles face challenges in properly storing video data captured by cameras, particularly due to temperature limitations of external storage media, which can lead to data loss or corruption when the system's temperature exceeds the media's heat-resistant threshold.
Innovation Solution
A video processing apparatus mounted on a vehicle that includes a processor and memory, which dynamically switches between storing video data in an external storage medium when the temperature is below a threshold and in an internal, heat-resistant memory system when the temperature rises, ensuring continuous video recording and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video is stored in external storage medium, then storage capacity is improved, but reliability deteriorates when temperature exceeds threshold
Solution Approach 1:
The system dynamically switches between external storage medium and internal storage device based on temperature conditions. When temperature is below threshold, external storage is used for high-capacity storage; when temperature exceeds threshold, the system automatically switches to internal storage to ensure data reliability, thus resolving the contradiction between storage capacity and reliability under varying thermal conditions
Solution Approach 2:
The temperature detection unit acts as an intermediary that monitors storage medium temperature and triggers automatic switching between storage destinations. This intermediary mechanism enables the system to transition from external to internal storage when temperature becomes harmful, maintaining both high storage capacity utilization and data reliability
2Reliability
If temperature monitoring and automatic switching is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The system performs self-service through automatic temperature monitoring and autonomous switching between storage destinations without requiring manual intervention. The temperature detection unit continuously monitors conditions and the storage control unit automatically executes switching decisions, improving reliability while keeping the control logic relatively simple and maintainable

AI summary
A video processing apparatus is mounted on a vehicle and stores a video from a camera that captures at least one of outside or inside of the vehicle. The video processing apparatus includes a memory that stores therein a computer program; and a processor that is connected to the memory. The processor performs processing by executing the computer program. The processing includes receiving the video; and storing the video in an external storage medium in a case where a temperature of the video processing apparatus is less than a predetermined threshold, and storing the video in a storage device incorporated in the video processing apparatus in a case where the temperature is equal to or higher than the threshold.
