Abstract:Aiming at the problems of high power consumption, poor global coverage and low efficiency of intelligent cold chain transportation system in the whole world, taking intelligent refrigerated container as the research object, this paper introduces an intelligent cold chain transportation terminal system based on LEO satellite and NB-IoT communication technology, and gives the system design, hardware design, software design, low power consumption design and test results of the intelligent cold chain transportation terminal system. The transport terminal system uses STM32 as the main controller and integrates temperature, humidity and location information sensors. It is compatible with LEO satellite and NB-IoT communication modes. The system can globally monitor the position, status and safety of refrigerated containers equipped with the intelligent terminal. Practical operation shows that the scheme is reliable and has certain popularization and application value.
