Port wireless asset management system based on ZigBee

The port is a gathering point and hub for water and land transportation, and a distribution center for industrial and agricultural products and foreign trade import and export materials. Due to the frequent movement of goods in and out of the port,Relying on traditional human resources for material management is not only easy to make mistakes, but also has poor real-time performance.HelicommexistZigBeeBased on technologyDeveloped a port wireless material management system and successfully applied it to a port in South Korea, which was recognized by customers.

solution
　The system architecture is shown in the figure, and the whole system isZigBeeSelf-organizing wirelessmeshThe network is the medium of information transmission.Sea entrance at the container yardAnd land entrances to wear tags for containers,2No,5After the No. base station detects the container, the system will automatically register the container into the warehouse, and at the same timemesh It locates it in real time within the network and stores the data in the database at the central end; when the container is shipped from sea or land,1No,6NoThe base station will detect the container, the system will automatically delete the cargo record, store the cargo path and other information in the central database, and then workThe staff reclaimed the tags and the whole process was announced. From entering the port to exiting the port, the entire process of the container is monitored by the system.High real-time of the systemThis not only improves the work efficiency of port staff, but also provides more reliable data protection for the port’s asset management system.
