先进超导托卡马克实验装置等离子体密度远程控制系统

Plasma Density Remote Control System of Experimental Advanced Superconductive Tokamak

在先进超导托卡马克实验装置实验阶段,与密度控制有关的实验数据和信息存储在实验现场的计算机系统中,对这些数据进行分析研究时需要到现场才能采集或获取。设计了托管控件,用于等离子体密度远程控制系统业务逻辑的封装,实现了增强型的B/S计算结构,解决了远程控制过程中复杂的科学计算,并实现了实验进程的同步监视。还在数据交换机制中部署了Web Services和Data File Services两层服务,有效地维护了数据传数链路的松散耦合特性。实验证明,它不仅实现了密度的远程控制功能;而且在目前的托卡马克实验情况下,具有较好的数据传输性能。

In Tokamak experiments, experimental data and information on the density control are stored in the local computer system. Therefore, the researchers have to be in the control room for getting the data. Plasma Density Remote Control System （DRCS）, which is implemented by encapsulating the business logic on the client in the B/S module, conducts the complicated science computation and realizes the synchronization with the experimental process on the client. At the same time, Web Services and Data File Services are deployed for the data exchange. It is proved in the experiments that DRCS not only meets the requirements for the remote control, but also shows an enhanced capability on the data transmission.
