Design And Implementation Of Vehicle Traveling Data Recorder And Background Data Analysis Software

Vehicle Traveling Data Recorder is a digital electronic record set which can collect and store vehicle's running velocity, time , distance and other state information related, and it can transmit data via interface. Vehicle Traveling Data Recorder not only can hold out traffic violations, restrict driver's bad drive habit, but also can prevent traffic accidents from happening, and provide scientific, veritable origin datum for tipstaffs to analyze and dispose of accidents. It plays a very important role in transportation management.The data analysis software of Vehicle Traveling Data Recorder can analyze original datum which are recorded by the recorder according to the national standard. It can read original datum of the recorder, and be provided with query, statistic, schematics, parameter setting, purview management and other functions.According to the national standard of Vehicle Traveling Data Recorder and concrete practical criterion of Shaanxi, the article introduces process of research and development in Vehicle Traveling Data Recorder system, including recorder host and data analysis software. In this article, general situation of the subject is presented, system design and functions of the recorder are briefly described. On the basis of it, combined with work experience, process of design and realization to data analysis software is emphatically depicted; furthermore, embedded USB host in the recorder on the base of SL811HS chip is discussed. After the rigorous testing, Vehicle Traveling Data Recorder works well, and its performance measures up. Data Analysis Software with graphs and texts is developed by Visual C++, and Its interface is friendly and easily operated.
