Abstract: In order to ensure intelligent welding process is suitable for production of structural member of support, improve equipment utilization rate, guarantee welding quality, and give full play to advantages of intelligent welding workshop, production information management system of intelligent welding workshop for hydraulic support based on MES was studied. The overall system model and its network architecture were established, functional requirements of the system were analyzed, and the system database model was established. The design of data acquisition module of intelligent welding workshop production information was introduced. The module realizes comprehensive collection of scene information of workshop. The practical application results show that the system realizes effective data communication between enterprise decision-making level and production site, and ensures production quality and efficiency of hydraulic support.
