In order to improve the assembly efficiency of the workshop, reduce the workload of workers, and achieve accurate collection and efficient management of product quality data, an intelligent control system with a four levels software framework for a certain assembly workshop was designed and implemented based on technologies such as digitization, Internet of Things, and data collection. The workshop intelligent control system receives production plans from the upper level manufacturing execution system, parses them, and distributes key information to the lower level systems such as production lines, AGV, and stereoscopic warehouses. Through internal and external interfaces, it realizes material distribution, task status monitoring, data perception, and other functions to efficiently complete workshop product assembly, while accurately and reliably obtaining its quality data, achieving intelligent control of the assembly process.
