摘　　要：在现代物流的各个环节中,分拣系统是其中关键的一环。目前,并不能保证分拣机构精准高效地运行,时常会发生分拣错误,给物流及其相关领域带来了巨大的损失。文中设计了一种基于嵌入式技术的物流复检系统,以达到修复分拣错误的目的。该研究中针对目前常见的以条码作为分拣识别的分拣系统,在分拣的末端下线口处使用终端节点采集条码信息。终端节点移植实时操作系统RT-Thread作为软件平台,同时使用新型的Cortex-M7处理器来提供物质保障。终端节点使用高可靠性的CAN总线与主控节点交互。主控节点使用ARM-Linux架构,在研究中主要完成ARM-Linux的交叉编译开发环境的搭建、各种库和文件系统的制作、Linux内核的移植和所需驱动的开发,最终实现既定研究目标。In every link of modern logistics,sorting system is a key link.At present,it can not guarantee the precise and efficient operation of sorting institutions,and sorting errors often occur,which brings huge losses to logistics and related fields.This paper designs a logistics reexamination system based on embedded technology to repair the shortboard of sorting errors.In this study,aiming at the current common sorting system using bar code as sorting recognition,the terminal node is used to collect bar code information at the terminal offline port of sorting.Terminal node transplants RT-Thread as a software platform and uses a new Cortex⁃M7 processor to provide material support.The terminal node uses a highly reliable CAN bus to interact with the main control node.The main control node uses the ARM⁃Linux architecture.In the research,it mainly completes the construction of the cross⁃compiler development environment of ARM⁃Linux,the production of various libraries and file systems,the transplantation of the Linux kernel and the development of the required drivers,and finally achieves the established research objectives.Sorting plays an important role in the modern logistics in order to ensure the accuracy.
