摘要
本文介绍了建立在以32位三星的S3C44B0X微处理器为核心的嵌入式系统平台上的汽车黑匣子的设计和开发。本系统主要解决的问题是:1.关于汽车行驶状态信号数据的采集和处理。2.USB接口的设计,使黑匣子中记录的数据能够通过USB接口与PC或者PDA进行通信。最后经过系统集成,本系统可以很好的运行。另外在本系统设计中还采用了嵌入式操作系统uClinux,并对其移植过程做了一定的研究。
In this paper a vehicle black box based on the embedded system, which takes 32 bit microprocessor of Samsung＇s S3C44bOX as nucleus, is presented. The mainly matters solved are the collection and processing of the vehicle＇s signal and the design of the interface of USB by which the recording data in the black box can communicate with PC or PDA. Finally the system, which be integrated, can be very good operation. In addition, μClinux is adopted in the system, and some research works for μClinux porting have been done.
