摘要
在嵌入式軟件開發(fā)技術(shù)快速發(fā)展的今天,我們身邊的嵌入式產(chǎn)品越來越多,基于嵌入式系統(tǒng)的應(yīng)用程序大量出現(xiàn)。本文介紹了基于嵌入式系統(tǒng)的汽車行駛記錄儀數(shù)據(jù)采集軟件的開發(fā)過程。概述了UDP通信、串口通信的相關(guān)技術(shù)。結(jié)合eMbedded Visual C++ 4.0,Microsoft Visual C++ 6.0 等開發(fā)工具,使用Visual C++技術(shù)分析、設(shè)計(jì)和開發(fā)了針對(duì)傳統(tǒng)記錄儀的一些缺陷而改進(jìn)的記錄儀數(shù)據(jù)分析軟件。論文主要闡述一個(gè)記錄儀數(shù)據(jù)分析軟件的開發(fā)過程和相關(guān)技術(shù)。
該數(shù)據(jù)分析軟件主要包括完成記錄儀的國家標(biāo)準(zhǔn)命令的實(shí)現(xiàn),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(wǎng)數(shù)據(jù)通訊功能,比如尋找地標(biāo),尋找警察,向警察發(fā)送數(shù)據(jù)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
