Abstract:

Supervisory control and data acquisition (SCADA) framework of bottom layer and top layer, interlock protection, operational mode and system implementation were described. In bottom layer, vacuum pumping system and fuelling system are adopted to two different topological structures of optical fiber ring network. The top layer uses the experimental physical and industrial control system (EPICS) architecture to meet the requirements of the large-scale scientific facility. The topological structure of optical fiber ring network and EPICS framework are combined to develop the largely distributed SCADA system. Test results show that the control system is stable and reliable. The SCADA system provides not only reliable support for EAST, but also a good reference for developing other SCADA system of large-scale scientific facility in the future.
