摘要
设计了一种针对危险品运输车辆的智能车载终端,在STM32平台上实现车辆定位、车况监控、自动报警等功能,具有友好的人机交互界面。文章简要介绍系统的硬件结构,详述了车载终端软件系统驱动层和应用层的实现过程,对设定加速度传感器中断阈值做了从理论到实际的具体说明,并通过自主搭建的实验平台加以验证。该车载终端智能化程度高,具有较好的实际应用价值,尤其适用于危险品运输车辆的追踪监控管理需求。
The design and realization of an intelligent logistic vehicle terminal is described in this paper.Based on STM32-series platform,this terminal can locate the car,monitor its condition and alarm automatically,with friendly user interface as well.The composition of its hardware system is briefly introduced.The realization process of its software system both in driver and application layer is also elaborated;setting threshold for accelerometer＇s interruption is particularly explained from theory to practice,and verified by autonomous-setup experiment platform.The advantages of this terminal are intelligence in practical applications,which fits especially to dangerous chemical transporters.
