[0002] The assembly production process in the military production environment is a typical complex discrete assembly, facing the problems of parallel scientific research and production, high process flexibility requirements, a wide variety of products, small and diverse batches, and high quality reliability requirements. Through the analysis of the assembly production process in the military production environment, it is found that there are many manual operations, difficulties in real-time collection, transmission and storage of production process information, the inability to summarize product inspection data in real time, and the lag of production data. At present, the personnel information, supporting data, assembly process, inspection results and other data of most production lines are transmitted by oral notes. This has caused problems such as low efficiency, easy errors, incompleteness, and asynchrony, which seriously affects the quality control of the production process, and it is impossible to achieve rapid traceability and analysis of products.
