新型汽车行驶记录仪设计

Design for new type data recorder of vehicle traveling

汽车行驶记录仪与飞行器中的记录仪发挥着同样的重要作用,近年来国内外都在推广其应用,有鉴于此,参照国家标准(GB/T 19056-2003),以及国内外近几年的研究成果,设计了在实时操作系统μC/OS_II下以ARM9微处理器芯片为核心的汽车行驶记录仪。设计的重点和难点是系统任务的合理调度,数据采集和处理,数据存储管理部分是。设计方法吸取了部分前人的研究成果,同时对软件和硬件部分进行了创新设计。数据分析软件使用了功能强大的MATLAB软件。最后进行初步的模拟试验,分析结果,以证实设计的可行性。

The traveling data recorder of vehicle and airplane play the same role in travelling,which becomes popular at home and abroad in recent years.Therefore ,a new design for the vehicle traveling data recorder is done in it based on the ARM9 core and the μC/OS-Ⅱ that is a kind of real time operation sys- tem according to the national standard of China after referring to the newest research at home and abroad these years.The key and difficult point of the design is to schedule the task ,collect and process data as well as store and manage the data.The new design is created in software and hardware based on the work of the former designers.MARLAB software with powerful function is applied in data analyzing.Finally some prima- ry simulation experiments are done to testify the feasibility of the design.
