沉浸式虚拟EAST中部件安装方案生成技术研究

In the EAST experiment, the properties and states of the plasma, and the engineering parameters of the EAST device are measured and analyzed by a variety of diagnostic methods. With the operation of the experiment, the approaches of diagnosis and measurement are constantly updated, and the diagnostic systems need to be updated accordingly. However, the position conflicts would inevitably occur due to the traditional diagnostic marker from diagnosis personnel according to the installation location of the part drawing, leading to modification after the re-discussion with other diagnosis personnel. Additionally, the confined environments of EAST also bring inconvenience for installation. Therefore, the technology of scheme generation of an immersive component installation should be urgently pursued. Aimed at the actual requirements of physical experiments, the digital technology of component installation and design process based on multi-user and multi-detail of level, as well as the technology of virtual installation and cooperative discussion base on hierarchical collision detection are proposed. Starting from the diagnosis of electromagnetic measurements, the scheme generation system of immersive virtual EAST component installation is established to provide a reference for researchers to access the real installation process, reduce the conflict of component positions, and improve the installation efficiency of the components. Furthermore, the results of this study can also be applied to other nuclear fusion devices.

在EAST实验运行过程中，等离子体的性质、状态和装置的工程参数等是通过多种诊断方式测量并分析推算得出的。而随着实验的运行，诊断和测量方式不断更新，诊断部件也相应的需要更新，传统的各诊断组独立的根据图纸标记诊断部件安装位置的方式难免会引起位置冲突，从而需要与相关各诊断组进行讨论并修改；另外，EAST装置真实环境情况复杂也给部件安装过程带来不便，因此迫切需要研究一种沉浸式部件安装方案生成技术。本项目以EAST托卡马克装置为研究平台，针对EAST物理实验的实际需求，提出“基于多用户多细节层次的部件安装过程数字化技术”及“基于分等级碰撞检测的虚拟安装与协同讨论技术”，并以电磁测量等诊断入手初步建立沉浸式虚拟EAST部件安装方案生成系统，为科研人员提供一个虚拟化平台，为进入真实安装过程提供参考，减少部件位置冲突，提高部件安装效率。此外，这项研究的成果也可应用于其他核聚变装置中。
