Description

Method for Data Lighter Processing and Effective Visualization in a 3D Digital Twin of Nuclear Facility and Electronic Device Using the Same The embodiments of the present disclosure relate to a data lightweighting and efficient visualization method for effectively implementing a 3D digital twin of a nuclear reactor facility (specifically, nuclear facilities and radiation-related facilities) and an electronic device using the same. More specifically, the invention relates to a system that optimizes data transmission speed and enhances visualization by adaptively adjusting the resolution of objects within a nuclear reactor facility to lightweight the data. Digital twin technology may be necessary to transmit and receive radiation dose data in real time to display radiation exposure levels at nuclear reactor facilities. A digital twin is a technology that creates a virtual environment identical to a physical reactor to monitor and simulate radiation levels; by collecting real-time data from various sensors within the reactor, it enables the prediction and response to radiation exposure risks. Through this, managers of nuclear reactor facilities can immediately identify changes in radiation levels, ensure the safety of radiation workers, and establish efficient operational plans. However, transmitting radiation data in real time from a digital twin requires handling a massive amount of data, which leads to a significant increase in communication costs and network load. Therefore, data lightweighting may be essential to optimize system performance and communication speed. Data lightweighting can efficiently transmit necessary information, reduce communication costs, and increase response speed by reducing the complexity of 3D models or optimizing transmission cycles. Through this, there may be a need for a method to support efficient operation while maintaining system stability, even while monitoring radiation data from reactor facilities in real time.
