By sorting out the process data requirements of the intelligent workshop manufacturing execution system or intelligent processing production line, the key technologies of process data digitalization management are broken through to form the specification requirements of multisource data. The data extraction and organization based on the data specification are studied, and the process data is applied to practical uses. Through the digital management of process data, the manufacturing execution control system of workshop can be better implemented, so as to promote the engineering application of shipbuilding processing intelligent manufacturing equipment for shipyard.
