摘要
针对现代生活中快递在运输过程中出现的丢失、损坏,客户对重要包裹在运送途中的担心等问题,提出一种基于全球卫星导航系统(GNSS)的物流信息跟踪系统设计。基于嵌入式实时操作系统,以STM32L151RCT6单片机为主控模块,驱动传感部分(GNSS位置传感器、温湿度传感器、加速度传感器)采集包裹的各项物流信息,并通过窄带物联网(NB-IoT)通信将物流信息传输至快递公司的物联网云平台;用户通过Web网页即可查询包裹的物流信息,包括精确位置、温湿度、运动状态等。测试结果表明,该系统能够完成对包裹信息的跟踪和稳定上传,其定位跟踪精度在2.5 m以内,能够实现对快递包裹的集中化、规模化管理。
Aiming at the loss and damage of express delivery in the transportation process in modern life,and the customer’s worry about important packages in transit,a logistics information tracking system design based on the Global Navigation Satellite System(GNSS)was proposed.Based on the embedded real-time operating system,the STM32L151RCT6 single-chip microcomputer was the main control module,which drived the sensing part(GNSS position sensor,temperature and humidity sensor,acceleration sensor)to collect various logistics information of the package,and logistics information was transmited to the cloud platform of the internet of things of the express company through the Narrow Band Internet of Things(NB-IoT)communication.Users could query the logistics information of the package through the web page,including the precise location,temperature and humidity,and movement status.The test results showed that the system could complete the tracking and stable upload of package information,and its positioning and tracking accuracy was within 2.5 meters,which could realize centralized and large-scale management of express packages.
