LHD（大型螺旋装置）数据处理系统的设计目的是为了处理每10 s短脉冲实验600∼900 MB的海量诊断数据。它于1998年3月准备了第一个等离子体实验。最近数据量的增加迫使采用完全分布式系统结构，该结构使用并行的多个数据传输路径并将所有计算机功能分类为客户端和服务器。每个诊断设备安装的基本元件由两种服务器计算机组成；数据采集PC/Windows NT和实时诊断控制VME/VxWorks。为了应对多样化的设备控制通道和诊断数据，本系统的开发完全采用面向对象的方法。它不仅减轻了开发负担，而且拓宽了软件的可移植性和灵活性。基于百兆FDDI的快速网络将重新集成分布式服务器计算机，使它们可以充当用户的一台虚拟宏机。 LHD数据处理系统所采用的网络方法完全基于TCP/IP互联网技术，它为远程协作者提供了与本地参与者相同的访问能力。
The LHD (large helical device) data processing system has been designed in order to deal with the huge amount of diagnostics data of 600∼900 MB per 10 s short-pulse experiment. It prepared the first plasma experiment in March 1998. The recent increase of the data mass obliged to adopt the fully distributed system structure which uses multiple data transfer paths in parallel and categorize all of the computer functions into clients and servers. The fundamental element installed for every diagnostic device consists of two kinds of sever computers; the data acquisition PC/Windows NT and the real-time diagnostics control VME/VxWorks. To cope with diversified kinds of device control channels and diagnostics data, the object-oriented methods are utilized wholly for the development of this system. It not only reduces the development burden, but also widen the software portability and flexibility. One hundred Mbps FDDI-based fast networks will re-integrate the distributed server computers so that they can behave as one virtual macro-machine for users. Network methods applied for the LHD data processing system are completely based on the TCP/IP internet technology, and it provides the same accessibility to the remote collaborators as local participants have.
