The second model is from intelligent manufacturing production units (equipment and products) to smart factories. In the discrete manufacturing fields of machinery, automobile, aviation, shipbuilding, light industry, household appliances and electronic information, the core purpose of enterprise development of intelligent manufacturing is to expand the product value space, focusing on single equipment automation and product intelligence, based on production efficiency. And the improvement of product performance achieves value growth.
Therefore, its intelligent factory construction mode is as follows:
First, to promote the intelligentization of production equipment (production line), to establish a workshop-level intelligent production unit based on CPS system by introducing various intelligent equipments that meet the production requirements, and to improve the precision manufacturing and agile manufacturing capabilities.
The second is to expand the value-added services based on product intelligence, use the intelligent devices of the products to achieve interoperability with the CPS system, support remote fault diagnosis and real-time diagnosis of products;
Third, promote the integration of workshop-level and enterprise-level systems to achieve production and Seamless integration of operations and information sharing between upstream and downstream enterprises, and collaborative innovation based on horizontal value networks.
The fourth is to promote the integration of production and service, to achieve service transformation based on smart factories, and to improve industrial efficiency and core competitiveness.
For example, Sany Heavy Industry's No. 18 plant is a final assembly workshop with multiple assembly lines such as concrete machinery, road machinery, port machinery, etc., and through the establishment of a “component work center island” in the production workshop, that is, unitized production, each type of component is All processes from production to offline are concentrated in one area, as if all production was completed in a separate “island”. This kind of organization breaks the shortcomings of the traditional process production line in a straight line arrangement. Under the condition that the manufacturing process of the structural parts is not changed and the production personnel are not increased, the purpose of reducing the floor space, improving the production efficiency and reducing the running cost is achieved. . At present, Sany Heavy Industry has built intelligent systems such as workshop intelligent monitoring network and tool management system, public manufacturing resource positioning and material tracking management system, planning, logistics, quality control system, production control center (PCC) central control system, etc. The unit has jointly developed intelligent loading and unloading robots, intelligent monitoring network for workshop equipment based on DNC system, intelligent warehouse and AGV transportation software and hardware systems, material and resource tracking and positioning system based on RFID equipment and wireless sensor network, and advanced planning and scheduling. Key core intelligent devices such as system (APS), manufacturing execution system (MES), logistics execution system (LES), online quality inspection system (SPC), and production control center management decision system, which realize the tracking of manufacturing resources and the monitoring of production processes. Balanced mixed flow production under the control of planning, logistics and quality integration.
