Aiming at the lack of effective human-computer interaction methods and the low degree of visual monitoring of the real-time running status of the equipment in the production process of typical aviation product assembly production lines

a technical solution for operation status monitoring of processing equipment visualization and simulation analysis of processing equipment based on digital twin theory is proposed. The program includes model construction and optimization

NC program analysis and pre-processing simulation

software and hardware communication and data transmission

real-time data acquisition and simulation functions. Finally

it is verified on the assembly line of the aircraft engine external culvert assembly that the scheme can be used for NC program processing simulation analysis

online monitoring of equipment status during operation online monitoring of production line status information and real-time three-dimensional simulation.
