Research and Realization of Virtual-Real Control of Robot System for Off-Heap Detector Assisted Installation Based on Digital Twin

In order to explore the application of digital twin technology in the operation and maintenance of nuclear equipment, based on the installation and replacement of out-of-core detectors in the nuclear power plant of the Guohe No. 1 demonstration project, a digital twin system of robots for auxiliary installation of out-of-core detectors based on digital twins is proposed. Taking the process of the robot transporting the out-of-core detector as the research object, a digital twin of the robot is established, and the two-way interaction between the twin model and the control system is realized by using the ADS (Automation Device Specification) communication protocol. The experimental results show that the system has high feasibility and can provide a basis for the transparent and real-time visualization of the robot operation process. Therefore, the application method of digital twin technology proposed in this paper can serve the operation and maintenance of nuclear power, and is of great significance to promote the digital transformation of nuclear power in my country.
