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。 This article describes the design and development of a car black box built on an embedded system platform with a 32-bit Samsung S3C44B0X microprocessor as its core. The system to solve the problem is: 1. On the car driving signal data collection and processing. 2.USB interface design, so that the data recorded in the black box through the USB interface to communicate with the PC or PDA. Finally through the system integration, the system can be very good run. In addition, the system design also uses embedded operating system uClinux, and to do some research on its migration process.
