Problems solved by technology

[0005] At present, there are existing patented technologies on how to improve the quality of ship segmented construction, such as patent CN105785944 B disclosing a "hull construction precision control process method and system", Patent CN 103434611 A discloses a "high-precision control construction method for large ships". The two patents manage and analyze the data that affects the quality of the construction process, and perform quality control by comparing or setting compensation amounts, but only for The quality control of the processed components cannot predict the components to be processed in advance, which is passive control; patent CN 105808891 B discloses "a system precision control method for segmental digital manufacturing of ships". In this patent, there is no analysis and simulation The construction process technology still fails to predict the quality to be processed in advance

Abstract

The invention discloses a twin data-driven ship assembly product quality management and control system and a configuration method. The system is composed of intelligent construction equipment, a dataacquisition module, a wireless transmission module and a construction quality management and control module. The intelligent construction equipment forms an assembly product manufacturing production line according to a construction process, the data acquisition module acquires assembly product process data and equipment current operation state data in real time, and the wireless transmission module is used for communication between the data acquisition module and the construction quality control module. The construction quality management and control module firstly fuses process data, equipment state data and historical data to form twin data. Secondly, a multi-digital twinning model is established and simulated to obtain process parameters to be optimized, the process parameters are optimized according to a deep neural network algorithm, and finally the process parameters are converted into an instruction which can be recognized by intelligent construction equipment, thereby finishingquality control of a ship assembly product. The invention further provides a configuration method of the system, and the operational feasibility of the system is further explained.
