Design and implementation of EAST diagnostic data acquisition management system

To address the low degree of automation in configuring acquisition devices and the lack of fault monitoring mechanism in the diagnostic data acquisition system of the EAST (Experimental Advanced Super-conducting Tokamak), a B/S architecture-based EAST diagnostic data acquisition management system is designed. This system utilizes Mycat and MySQL to build a distributed storage environment, supports remote configuration and management of acquisition devices, and adopts EPICS framework and WebSocket protocol to realize real-time monitoring and alarm of data acquisition units. Experimental tests have demonstrated that the system can run stably and meet the requirements of EAST experiments.
