Abstract: One of the project missions of the whole superconducting tokamak EAST is the realization of 1 000 second plasma discharge. Correspondingly, it’s necessary to construct a high speed distributed Real-Time Data System(RTDS) with the capacity of real-time data transmission, storage and distribution. This paper describes the hardware structure of the EAST RTDS from the aspects of function structure and realization method. Its interfaces and realization methods based on time slice mechanism are also analyzed at length.

Key words: EAST tokamak, distributed, real-time, data system, time slice
