摘 要 根据飞机“黑匣子”的原理而研究的监控记录汽车实时运行状况的系统，俗称“汽车黑匣子”。汽车黑匣子，又称汽车行驶记录仪,是可以实时采集并记录汽车行驶状态的电子仪器,它对保证行车安全和发生道路交通事故后的责任分析等有着重要的作用。 本系统完全依照汽车行驶记录仪的国家标准而开发的，以MSP430超低功耗单片机作为主控器件、以FM24C04铁电存储器作为实时存储器,能够对汽车行驶时的转向灯、制动、超速超时告警、轮速信号等信息进行采集、处理、记录。记录仪利用RS232串口与PC机连接通讯，将这些记录数据通过数据分析处理软件对实时记录的数据进行后处理分析。 本文详细论述了汽车行驶记录仪系统主机模块软硬件的设计与实现，并且介绍了上位机管理分析软件的设计。论文首先介绍了课题的研究背景，并对国内外汽车行驶记录仪的研究现状进行了概括，在此基础上提出了本课题需要完成的目标。阐述了基于嵌入式系统的总体设计构思以及各个功能模块不同方案优劣的比较，并对最终方案进行了描述，此后详细介绍了各主要功能部件的特点及应用。最后，论文对整个系统的功能和特点进行了总结，并对下一步工作以及记录仪今后的发展进行了展望。 关键词：汽车黑匣子；MSP430；超低功耗 Abstract According to the aircraft black box principle and the study of real-time monitor the operation of motor vehicle records of the system, commonly known as car black box.Automobile black box, also known as Vehicle Traveling Data Recorder,which can be collected and recorded in real-time vehicle status with electronic devices, it is to ensure traffic safety and road traffic accidents occurred in the responsibility of the post-analysis plays an important role. This system is exploited completely according to National standard of vehicle traveling data recorder,uses MSP430 ultra-low power single-chip microcomputer as the master device, FM24C04 ferroelectric memory as a real-time memory.It is able to record ,collect , process the information of car lights, braking, speeding time-out warning and wheel speed.Recorder using RS232 serial communications with the PC connected to these records through data analysis data processing software for real-time data recorded in post-processing analysis. This thesis mainly describes hardware and software designing ofVTDR mainframe．VTDR developing background is first introduced．Then domestic and OVCIadeveloping actualities are summarized,and based Oil the sulnnlari?蜥on the aim ofVTDR developing is set forth．In the following part,the thesis discusses the designingconception of the whole system and different plans of each run．ion module．At last,the fmal designing plan is described in detail．In the last chapter
