Multi-channel data acquisition system and method suitable for EAST diagnosis

Abstract

The invention discloses a multi-channel data acquisition system and method suitable for EAST diagnosis, and the system is provided with a man-machine interaction main interface which comprises a shot number monitoring module, a multi-channel data acquisition module, a data backward-reading module, and a state recording module. The shot number monitoring is composed of a manual shot number sending analysis module and a general control system shot number sending analysis module; the multi-channel data acquisition module is composed of a channel integration module, an acquisition parameter configuration module and an acquisition data drawing module; the data read-back module is composed of a read-back data analysis module, a read-back process control module and a read-back data drawing module; the state recording module is composed of a message display character string; according to the system program, automatic operation of the system program can be realized by reasonably controlling functional programs such as the shot number monitoring module, the multi-channel data acquisition module and the data read-back module.

Description

technical field [0001] The invention belongs to the technical field of EAST tokamak devices, and in particular relates to a multi-channel data acquisition system and method that can be adapted to EAST diagnosis. Using LABVIEW as a development platform to meet the requirements of the EAST tokamak device discharge experiment, it can realize the design of the multi-channel data acquisition system and method suitable for EAST diagnosis. Background technique [0002] In the experimental research of controlled nuclear fusion, the EAST tokamak device is one of the typical fully superconducting tokamak magnetic confinement devices. In the normal discharge process of the EAST device, in order to be able to study the relevant information of the magnetically confined plasma, it is necessary to establish different EAST diagnostic data acquisition systems. During the construction of the system platform, the number of detectors involved, the position distribution and the measured physical...

Problems solved by technology

[0003] Under the Window system, most of the existing EAST-related acquisition programs developed by non-professionals have the following deficiencies in the following aspects. First of all, in terms of function calling, the "static calling" method is basically used to load program functions during the function calling process. Modules, that is, no matter whether the program function modules are used or not, as long as the system program runs, all the function modules will be added to the computer memory, which will consume a lot of computer memory resources; secondly, in terms of scalability and stability, due to the lack of certain Hierarchical structure, expansion of new functional modules and modification time-consuming and laborious, the effect is not ideal, in the complex electromagnetic environment, it is easy to cause abnormal operation of computer programs; moreover, in terms of portability, most of the existing non-professional development The EAST diagnostic collection programs are all executable files, and the versatility and portability are basically non-existent. When there are different channels and physical quantities for collection and processing requirements, they need to be redeveloped, resulting in a waste of resources and energy.
