摘要
本文实现了基于嵌入式音像信号处理技术来实现新型长途客车运营状态记录仪。介绍了系统设计的总体结构及软硬件组成,在软件层技术中移植了ARM-Linux操作系统,选取Cramfs+jffs2组合作为的嵌入式文件系统,重点研究了音频采集和图像压缩的实现机理,成功地实现了智能记录功能。
The record analyzer for the operation of new vehicle is designed by the embedded sound and image processing technology. The whole framework, the design of software and hardware of the system are introduced. The ARM-Linux operation system is ported in the software technology. The embedded system selects the Cramfs combined with jffs2 . The theory of sound ＆ image acquisition, and image compression is analyzed. The intelligent ability of record is success- fully realized.
