Research on Key Technologies of Smart Logistics Dynamic Positioning Based on NB-IOT

Abstract

Abstract This study takes the large-scale freight yard in The free trade zone of Xinjiang and cargo reloading in international railway transit as the prototype scene, and takes NB-IoT network as the core to realize dynamic positioning electronic tags for people, vehicles and containers through Beidou positioning module and RTK technology.Finally, the positioning information will be transmitted to the command center through integrated NB-IoT communication function, and the three-dimensional simulation of the freight yard will be realized by using Threejs to build the intelligent logistics cargo dynamic real-time positioning system with the advantages of low power consumption, low cost, wide and deep coverage, massive connectivity, and precise positioning, so as to realize the role of reducing cost and improving logistics efficiency in intelligent logistics.
