| Abstract |
Power subsystem has been upgraded for energy improvement of the BEPCII Linac. As a result, new control system was in need. This paper proposes the designing and implementation about the power-supply control system. There are 156 sets of power supply in the system, which is divided into 6 parts, according to function. The control system is intended to make operations more convenient and efficient in beam regulation, which provides functions to meet such situations, like single regulation; restore the beam configures from data files; one-button to switch the electronic polarity (E-/E+). What’s more, the software provides a method of slow-change to protect the power supplies, when value change is too steep. Compare to the old system, this new software is more maintainable and extensible. This software is based on Qt, the GUI library for C++, and connects to the control box through the EPICS (Experimental Physics and Industrial Control System). The whole 156 sets of power supply are controlled by control boxes, which is ARM+FPGA (CPLD)-Structure front-end IO. This control system has assembled in BEPCII LINAC in September, which plays an important part in the following working.
