摘要
在嵌入式软件开发技术快速发展的今天，我们身边的嵌入式产品越来越多，基于嵌入式系统的应用程序大量出现。本文介绍了基于嵌入式系统的汽车行驶记录仪数据采集软件的开发过程。概述了UDP通信、串口通信的相关技术。结合eMbedded Visual C++ 4.0，Microsoft Visual C++ 6.0 等开发工具，使用Visual C++技术分析、设计和开发了针对传统记录仪的一些缺陷而改进的记录仪数据分析软件。论文主要阐述一个记录仪数据分析软件的开发过程和相关技术。
该数据分析软件主要包括完成记录仪的国家标准命令的实现，比如采集汽车速度，采集汽车疲劳驾驶等功能。还完成了无线局域网数据通讯功能，比如寻找地标，寻找警察，向警察发送数据等功能。

ABSTRACT
In computer technology fast developing today, the embedded products surrounded us is more and more. Application based on embedded massively appearances. This article applies the implementation process of a software of vehicle data recorder based embedded system, and has outlined related technology of the UDP, Serial Communication. The system is developed the onstage applying software like embedded Visual C++ 4.0，Microsoft Visual C++ 6.0, and using the Visual C++ programming technology analyze, design and develop a software of data vehicle data recorder aim at the bug of tradition vehicle data recorder. The paper mainly elaborates developed process and some related technologies of a software of vehicle data recorder.
The software of vehicle data recorder mostly complete the country’s standard function of the vehicle data recorder, like gather the speed of the vehicle, gather the tired data of the vehicle. And complete the function of data communication of the WLAN, like find mark of the road, find the police, send the data to the police.
Keywords：Embedded System, Network Communication, Serial Communication, Vehicle Data Recorder
