摘要
采用我国北斗(BD)定位系统,基于多种通信回传模式,设计开发了一种应用于物联网环境的物流定位跟踪通信终端。以ARM11处理器为核心,运用北斗二代卫星定位系统,与多种回传通信模块相结合,通过RFID采集相关物流信息,实现对物流的定位追踪。软件平台基于嵌入式Linux操作系统。在QT平台上实现对物流定位信息的采集和显示,并采用多模式的信息回传方式与中心站进行通信。实验表明,该终端可以满足物流环境下的应用需求。
In this paper,a multi-mode of logistics positioning and tracing terminal is designed based on BD positioning. The terminal positions and traces logistics is based on BD2 satellite positioning system ,and the invocations of logistics are collected through RFID which is based on combination of ARMll processor and multiple communication modules in logistics fields. The soft- ware platform is based on embedded Linux system. The system collects and displays the positioning information of linguistics, and sends the collected data to central control station by multi-mode of information transmission. The experiments show that the termi- nal meets the application requirement in logistics fields.
