摘要
在嵌入式軟件開發技術快速發展的今天,我們身邊的嵌入式產品越來越多,基于嵌入式系統的應用程序大量出現。本文介紹了基于嵌入式系統的汽車行駛記錄儀數據采集軟件的開發過程。概述了UDP通信、串口通信的相關技術。結合eMbedded Visual C++ 4.0,Microsoft Visual C++ 6.0 等開發工具,使用Visual C++技術分析、設計和開發了針對傳統記錄儀的一些缺陷而改進的記錄儀數據分析軟件。論文主要闡述一個記錄儀數據分析軟件的開發過程和相關技術。
該數據分析軟件主要包括完成記錄儀的國家標準命令的實現,比如采集汽車速度,采集汽車疲勞駕駛等功能。還完成了無線局域網數據通訊功能,比如尋找地標,尋找警察,向警察發送數據等功能。

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
