Design And Implementation Of Data And Information Management System For ICRH On EAST

Ion Cyclotron Resonance Heating (ICRH) is one of the most important auxiliary plasma heating, which has been widely used in many tokamaks. On the EAST, the ICRH system has the capability of 12MW high power with many developments. So all the experiments data, information of the system developments and solution of technology problems can be arranged, Such a platform of the data and information management system should be established, which can realize the data sharing and unified management conveniently.In this thesis, basing on the experience of the data storage and inquiry management system in the present tokamak devices, an optimized platform management system has been designed for EAST ICRH system. The data and information management system includes data acquisition, data storage, data optimization, data service, and data interactive platform. The design and implementation of data acquisition, data storage, data optimization and data interactive platform are described in this paper.The present situation of ICRH data acquisition system is analyzed in this paper. In the thesis, the method of thread blocking, time division multiplexing and unified data transmission protocol will be arranged. Some solutions for the problems on the data transmission in different storage formats to the server cluster, the long pulse data acquisition and the large data transmission are presented.With the demand of the data storage and data optimization, a new database system for EAST ICRH has been designed. It solves the difficult problems of database storage capacity and the storage of different types of experimental data. The server cluster is established, in which three sub-servers compensation with each other and the data storage structure system is optimized.In order to meet with the requirements of the experiment, and to enhance real-time interaction, the tools of NET Framework development platform and object-oriented development are applied. In the cases of the software features, the system modular and the function realization, the platform of the interactive workstation and the remote access based on C/S and B/S architecture are established; The problem of the real-time information exchange and sharing of laboratory personnel between the experimental data are also solved.In the recent ICRH experiments on the EAST tokamak, the data and information management system is proved to be available and to be full with the requirements in real-time, interactive and scalability.
