北斗车载行驶记录仪设计与实现

The Design and Implementation of Vehicle Traveling Data Recorder Using BeiDou Positioning Module

提出一种以北斗(BD)模块为核心,采用GPRS/CDMA模块和WiFi模块两种通信方式的北斗车载行驶记录仪方案。高集成、高速率、低功耗的ARM处理器以及具有自主知识产权的国产北斗双模定位模块采集车辆信息,可用GPRS/CDMA模块通过基站与管理中心通信,也可在车场入口处使用WiFi采集器近距离通信。采用软硬件协同设计,提高了终端可靠性,适合于车载应用环境。

In this paper a Beidou（BD） module as the core, using the GPRS/CDMA module and WiFi module backup each other to communication mode of vehicle traveling data recorder scheme. Using home-made Beidou Positioning Module acquisition vehicle information with independent intellectual property rights, adopting high integration, high speed, low power of ARM processor, it can use GPRS/CDMA module of remote communications to the management center, but also in the parking lot at the entrance to WiFi close acquisition vehicle information. The of design hardware cooperate with software, improve the reliability of the terminal, suitable for Vehicle application environment.
