基于BDS和GPRS的公交车车载终端的设计

Design of Bus Terminal Based on BDS and GPRS

为了解决传统公交车车载终端信息闭塞的问题,迎合智能交通的发展需求,通过北斗卫星定位系统和GPRS无线通信技术,设计了一种智能化的车载终端。其中,硬件部分以三星S3C2440A为主控芯片,对TD3026北斗定位模块、TSINTEC M66 GPRS通信模块及电源模块进行了电路设计;软件部分以Linux系统为平台编写了功能程序并进行了移植。最后,通过实车测试实现了车辆定位及车载终端与后台系统的数据通信。

To solve the problem of information block of traditional bus terminals and meet the development needs of intelligent transportation,this paper designs an intelligent vehicle terminal through BeiDou Navigation Satellite System and GPRS wireless communication technology.In the hardware part,Samsung S3C2440A is used as the main control unit and the circuits of TD3026 BeiDou positioning module,TSINTEC M66 GPRS communication module and power module are designed;in the software part,Linux system is used as the platform to write and transplant the function program.Finally,the data communication between the vehicle terminal and the background system and vehicle location is realized through real vehicle test.
