Traditional warehousing cannot meet the growing logistics demand and scale, and digital twin technology has become a key enabling technology for digital warehousing, which is of great significance to improve efficiency, reduce costs and ensure safety. This paper aims to study the intelligent storage workstation system for digital twin technology. Firstly, discuss the application architecture of digital twin technology, use Process Simulate (PS) software for ontology modeling, kinematic analysis and simulation prediction of intelligent storage workstation, and use TIA Portal V16 to realize PLC (Programmable Logic Controller) programming control. The twin model is constructed by OPC UA (OLE for Process Control Unified Architecture) to communicate with the actual work station, then the design of intelligent storage workstation is completed. This design provides a new solution for the intelligence, automation and high efficiency of logistics storage equipment.
