Research of Data Server Application Software for NBI Mechanical Control on EAST

A set of data processing software is presented in this paper for processing NBI spectroscopic data. For better and more scientific managment and querying these data, they are managed uniformly by the NBI data server. The data processing software offers the functions of uploading beam spectral original and analytic data to the data server manually and automatically, querying and downloading all the NBI data, as well as dealing with local LZO data. The set software is composed of a server program and a client program. The server software is programmed in C/C++ under a CentOS development environment. The client software is developed under a VC 6.0 platform, which offers convenient operational human interfaces. The network communications between the server and the client are based on TCP. With the help of this set software, the NBI spectroscopic analysis system realizes the unattended automatic operation, and the clear interface also makes it much more convenient to offer beam intensity distribution data and beam power data to operators for operation decision-making.

“…The working mode of transferring data from the DAQ device to the data server is based on standard TCP protocol. For convenient and effective network communication between different devices on EAST NBI control system, unified data transmission structure must be harmonized [5] . The definition of data header structure is shown in Fig.…”

One of the most important project missions of neutral beam injectors is the implementation of 100 s neutral beam injection (NBI) with high power energy to the plasma of the EAST superconducting tokamak. Correspondingly, it's necessary to construct a high-speed and reliable computer data processing system for processing experimental data, such as data acquisition, data compression and storage, data decompression and query, as well as data analysis. The implementation of computer data processing application software (CDPS) for EAST NBI is presented in this paper in terms of its functional structure and system realization. The set of software is programmed in C language and runs on Linux operating system based on TCP network protocol and multi-threading technology. The hardware mainly includes industrial control computer (IPC), data server, PXI DAQ cards and so on. Now this software has been applied to EAST NBI system, and experimental results show that the CDPS can serve EAST NBI very well.

“…Considering that different devices need network communication, an appropriate protocol and data package structure must be unified. Based on normal TCP (Transmission Control Protocol), an EAST NBI TCP protocol [5] is applied for the interaction between terminal devices in the NBI control network. In addition, to implement the communication of the data package safely and reliably, when a terminal receives a data package from another one, the first thing that must be performed is a cyclic redundancy check (CRC).…”

Neutral beam injection (NBI) heating is one of the most efficient auxiliary plasma heating methods for fusion devices. The data acquisition control system (DACS) with PXI (peripheral component interconnect extensions for instrumentation) data acquisition card for the first NBI system in the experimental advanced superconducting tokamak (EAST) is presented in this paper. As an important subsystem , DACS is designed to obtain physical measurement signals in the EAST NBI system and to deal and store these data with the Lempel-Ziv-Oberhumer (LZO) lossless data compression algorithm, as well as offer convenient data call-back and access interfaces to the user for examining and analyzing the data. Experimental results show that accurate data will ensure that researchers correctly analyze it and then properly adjust the experimental parameters or operation, so DACS should take a large step in improving experimental efficiency. The hardware and software sections are briefly presented in this paper, and now this system has been tested to be able to work reliably and steadily.
