Research And Realization Of Beidou Compatible Vehicle Terminal

With continuous increase of domestic car ownership, the difficulty of the traffic management has been also gradually increased, all kinds of traffic violation events have emerged endlessly, Travel security of the residents has been influenced seriously. With the use of the vehicle data recorder, not only it can be largely specification driving people’s behavior, thus reducing the occurrence of all kinds of traffic violation events, and it can also provide the analysis and identification of road traffic accidents to provide important basis. Since the development of vehicle data recorder, has from pure driving records data for the GPRS, BD2 / GPS car terminal.In this paper, based on this background, based on the concept of software engineering design and development, designing and developing a set of Beidou compatible vehicle terminal system, and completed the system design and implementation of the work, in this paper, the main work content of this paper can be summarized as four aspects: first, this paper expounds the function and structure of vehicle terminal, it gives the overall design scheme of vehicle terminal; Secondly, taking design and implementation of the car terminal hardware module, including microprocessor and its peripheral circuit, positioning module, GPRS communication module; Again, completed the software design and implementation of vehicle terminal, including BD2 / GPS module, Beidou satellite positioning automatic calibration coefficient of pulse application, electronic fence monitoring procedures. Finally, the application of car terminal network spreading were discussed and analyzed.
