基于STM32单片机及NB-IoT的智能快递包裹箱设计

Design of intelligent express packing box based on STM32 SCM and NB-IoT

为解决快递行业存在的包装物浪费、污染和保护个人隐私问题,设计了一款可重复使用的智能快递包裹箱.箱体内采用NB-IoT模块传送信息,采用GPS模块实时记录快递的地理位置,稳压模块用于给箱体提供稳定的直流电源;箱体上采用二维码记录收发件信息;箱体外采用无线方式充电.该设计可以帮助学生掌握通信、电路、电子设计和单片机等方面的知识,提升学生的工程实践能力和创新能力.

In order to solve the problems of waste, pollution and privacy protection in the express industry, a reusable intelligent express package box is designed. The NB-IoT module is used to transmit information, GPS module is adopted to record the geographical position of express delivery in real time, and voltage stabilization module is used to provide the stable DC power supply for the box. The two-dimensional code is applied to record the sending and receiving information on the box body, and wireless charging is used outside the box body. This design can help students to master the knowledge of communication, circuit, electronic design, SCM, etc., and improve their engineering practice and innovation ability.
