Study of Intelligent Express Box based on NB-IoT

摘要

In order to solve the problem of inconvenience of delivery and delivery of express delivery in today's society, this paper puts forward the design of intelligent express box system, which has the functions of positioning, intelligent lock, real-time monitoring, logistics tracking and so on. Location is realized by NB-IoT enhanced positioning mode, namely OTDOA positioning, which facilitates users to quickly find the required express box. Intelligent lock is implemented by STM32 and NB-IoT communication module. When the password matches, the NB-IoT communication module receives the unlock command from the cloud platform, and the unlock is controlled by STM32. During the user's use of a smart express box, owning the ownership of the express box, the logistics status and the switch status of the lock can be monitored in real time on the APP. "Intelligent Express Box" is a new way of delivery, dedicated to providing more convenience for the masses.
