摘　　要：先进托卡马克装置需要长脉冲放电实验运行,针对装置长脉冲放电实验的数据存储和交互技术是重要的研究内容之一。本工作设计了一种Web数据显示系统,系统采用ASP.NET架构和数据分段技术从MDSplus数据库读取分段数据,利用NI Measurement Studio控件库将数据显示在Web页面中。数据分段技术将长脉冲实验数据划分为多个较小的数据单元——数据段,用户可按需读取长脉冲实验数据中的部分数据段。同时系统制定了高效的分段读取策略,可准确、快速地显示用户所需的数据波形。Web数据显示系统在J-TEXT托卡马克上进行了测试,运行性能稳定,达到了系统的设计目标。Long pulse operation is the main character of advanced Tokamak , so the technology of data storage and human-data interaction are vital for dealing with the large data generated in long pulse experiment .The Web data display system was designed . The system is based on the ASP .NET architecture ,and it reads segmented-record data from MDSplus database by segmented-record technology and displays the data on Web page by using NI Measurement Studio control library . With the segmented-record technology ,long pulse data could be divided into many small units , data segments . Users can read the certain data segments from the long pulse data according to their special needs .Also ,the system develops an efficient strategy for reading segmented-record data ,showing the waveforms required by users accurately and quickly .The data-display Web system was tested on J-TEXT Tokamak ,and was proved to be reliable and efficient to achieve the initial design goal .
