摘　　要：采用嵌入式Linux与S3C2440处理平台,提出了基于事件触发的车载视频采集存储系统实现方案。视频采集存储模块各单元由USB高速接口衔接,保证了采集、存储的速度匹配。8051F040单片机判别模块与视频采集存储模块通过串口传递控制信息,协调地进行视频采集和存储。实验结果表明该方案可对各种不规范驾驶行为进行准确判断并分别进行高速、可靠的视频采集存储。方案实现成本低廉,便于大规模推广使用。The method for onboard video capturing and storing based on embedded Linux and S3C2440 was proposed. The storing was triggered by 8051F040 processing module. The different units of the storing module were connected through USB, which made it possible that the device could store as fast as capture. The 8051F040 processing module communicated with video capturing and storing module through serial port. The results showed that according to different situation, the video could be captured and stored reliably at a high speed. This method can be realized with low cost, thereby it can be popularized on a large scale.
