Research on control system of aircraft structural component measurement equipment based on digital twins

Abstract Background. The coordinate measuring machines have been widely used in aircraft production measurement. However, the current level of intelligence of three coordinate measuring machines is low. Operators need to operate the equipment on site and read the measurement data, which restricts the improvement of detection efficiency. Methods . Applying digital twin technology to remote control of aviation structural component measurement equipment provides a new approach to solving the above problems. A control system for aviation structural component measurement equipment was developed based on digital twin technology. A digital twin of the measurement equipment was constructed in a virtual space, and the digital twin control system was constructed using the virtual real mapping method. Results . The system was tested for virtual real interaction to verify the rationality of the design of the control system for aviation structural component detection equipment, and experiments were conducted on virtual-real interaction communication testing. The experiment results shows that the communication delay is basically the same as the network delay, with an average of 25.1 ms, which can meet the real-time requirements of the digital twin system. Conclusions . The digital twin control system developed in this paper can be applied to remote control of detection equipment, which has a positive significance in shortening detection time and improving system response speed.
