摘要
为了实现对各类车辆的有效调度、协调控制和管理,提高物流运输的效率和安全性,针对物流系统应用环境,基于STM32微控制器设计开发了一种北斗导航与通信一体化的智能车载网络终端。该终端以STM32F103ZET6微控制器为核心,由北斗定位模块UM220、GPRS模块SIM900A和ZigBee无线网络模块组成。其中,UM220模块负责接收北斗卫星信号定位;SIM900A模块与物流中心通信;无线ZigBee模块用于传输车载物流相关信息。实验表明,该终端能自动完成车载网络数据的采集、处理和传输等功能,满足物流环境下的应用需求。
In order to implement effective commands, coordinated control and management of all kinds of vehicles, and improve transportation efficiency and security,an intelligent vehicle network terminal of Beidou positioning and communication integration based on STM32 is de- signed, in allusion to logistics system application environment. The microcontroller STM32F103ZET6 is used as the core. This terminal con- sists of three modules, which includes UM220 module, in charge of receiving beidou satellite positioning signals, SIM9OOA module, used for communicating with logistic center, and wireless ZigBee module, being responsible for transmitting logistic information. The experimental re- suits suggest that this terminal can automatically complete vehicle network data acquisition, processing and transmission, and other functions. It meets the application requirements of the logistic environment.
