Technical state control technology of aerospace product in production process based on Internet of manufacturing-related things

To solve the problem that information collection was not timely and information accuracy guarantee was costly because of gathering and recording on-site technical state in the production process with a manual manner, a technical state control technology based on Internet of manufacturing-related things was proposed. Through four-layer processing structure of information identification-data cleansing-data fusion-state evaluation, the technical state control model of aerospace product in production process based on Internet of manufacturing-related things was built. Aiming at the inaccuracy of collected data, a data cleaning method was put forward. A data fusion method based on rough set and D-S evidence theory was put forward to acquire technical state real-timely and accurately. The migration of technical state would be grasped through evaluation between physical state and target state. A space factory was taken as the application object to verify the feasibility of proposed technology.
