Description
EAST facility aims to support high-performance steady-state operation. EAST data acquisition system has been established to provide unified data acquisition and long-term data storage for various diagnostic systems, which is for offline data analysis. With the use of technologies such as digital twin and artificial intelligence, the demand of real-time data access in long-pulse operation is urgent. The exploration aiming at long-pulse real-time data publishing within the framework of EAST data acquisition system is ongoing and a prototype system has been established. The prototype system adopts ZeroMQ to transfer data. The DAQ unit acquires diagnostic data in real-time and transmits the data in time-sliced data format to the server with request/reply pattern. The server immediately publishes the data with publish/subscribe pattern and stores the data for long-term storage. Users which subscribe to signals can obtain real-time data for data visualization or data analysis. Tests are currently underway.
