Abstract :

The control system of Neutral Beam Injector (NBICS) is developed in accordance with the experimental operational characteristics of the EAST-NBI system. NBICS is based on the computer network technologies and classified according to the control levels, consists of three levels: a remote monitoring level, a server control level, and a field control level. The 3-layer architecture is capable of extending the system functions and upgrading devices. The chosen platform is a CPCI-based and PXI-based computerized network system. In each beam-line, there are three PXI/CPCI crates housing several boards for performing analogue signal acquisition, analogue voltage generation, signal conditioning, digital input detection and digital output generation. NBI Data Acquisition System consists of field instrument and measurement devices, servers and remote data processing terminals. Two server computers running CentOS 6.3 operating system act as control server and data server respectively. A virtual instrument for the timing system is developed with LabVIEW 2010 on the PXI-based platform. Both of the ion sources of a beam-line are designed to operate independently. Experimental results demonstrate that the visualization and automation of NBI experimental operations are successfully implemented by using the functions of remote monitoring, interlock protection, and data processing.
