High Intensity heavy-ion Accelerator Facility (HIAF) is a national important scientific and technological infrastructure being built by Institute of Modern Physics (IMP), Chinese Academy of Sciences. The Large-scale Accelerator Complex Control System (LACCS) developed by IMP will be used as the control system of HIAF. LACCS is divided into user layer, physical layer and device layer. In this paper, the power supply control system is described, which is used as the hardware driver of LACCS, provides full-function control interface for upper layers, and realizes remote control and reading back of power supplies. A large number of different types of power supplies are placed in many rooms, and each power supply room is equipped with a service host (called “local monitor”), which is integrated into the control system as a LACCS node. The power supply control system adopts multi-thread programming, communicates with upper LACCS nodes through CVLink protocol, and communicates with digital controllers of power supplies through self-defined protocol. Controllers send read back data via SFP to a self-defined FPGA card (called “data card”) and local monitor get data from data card via PCIe interface. The power supply control system can run stably and meet the control and reading back requirements.

摘要

High Intensity heavy-ion Accelerator Facility (HIAF) is a national important scientific and technological infrastructure being built by Institute of Modern Physics (IMP), Chinese Academy of Sciences. The Large-scale Accelerator Complex Control System (LACCS) developed by IMP will be used as the control system of HIAF. LACCS is divided into user layer, physical layer and device layer. In this paper, the power supply control system is described, which is used as the hardware driver of LACCS, provides full-function control interface for upper layers, and realizes remote control and reading back of power supplies. A large number of different types of power supplies are placed in many rooms, and each power supply room is equipped with a service host (called “local monitor”), which is integrated into the control system as a LACCS node. The power supply control system adopts multi-thread programming, communicates with upper LACCS nodes through CVLink protocol, and communicates with digital controllers of power supplies through self-defined protocol. Controllers send read back data via SFP to a self-defined FPGA card (called “data card”) and local monitor get data from data card via PCIe interface. The power supply control system can run stably and meet the control and reading back requirements.
