Abstract: Aiming at the problems of low material distribution efficiency, confusing coding and identification, and low degree of visualisation in special transformer manufacturing workshop, on the basis of analysing the transformer manufacturing process and logistics mode, a workshop material identification and coding system based on identification resolution is established, and the collection and modelling method of material information in the transformer workshop is researched. A framework of cooperative distribution system for workshop materials based on digital twin is proposed, and a digital twin scheduling model for material distribution with the goal of cost minimisation is constructed. Finally, a collaborative intelligent material distribution digital twin prototype system for special transformer manufacturing workshop is developed in combination with the actual production process, which realises the intelligent distribution and management of materials, and verifies the reasonableness and effectiveness of the method.

Key words: digital twin, material distribution, special transformer manufacturing workshops, identity resolution
