Research on Intelligent Cold Chain Transportation Monitoring System Based on Computer Internet of Things

Using STM32 as the main control chip, it fuses temperature, location and other data together. It is compatible with communication modes such as low-orbit satellites and NB-IoT to monitor refrigerated containers around the world in real time. Then, a 3D image dense matching method based on weighted SAD is proposed. The actual operation shows that the scheme has reliable performance and stable data transmission.
