Preliminary implementation of the real-time data sharing system based on RFM for EAST

摘要

For EAST experiments, the plasma control system (PCS) needs a lot of diagnostic data produced by the distributed subsystems of EAST to meet the requirements of steady-state plasma control. But due to the factors of different sampling frequencies of the subsystems and the signal distortion caused by long distance transmission, it's difficult for the PCS alone to acquire all the diagnostic data in each control cycle. So the real-time data sharing system is designed to solve the problem of real-time data transmission between the PCS and the subsystems so as to realize data sharing among the distributed EAST systems.
