基于CAN总线技术的PSM电源远程控制通信系统

摘要

In order to enhance the operation efficiency and manipulation reliability of the pulse-step-modulated (PSM) high voltage power supplies of the auxiliary heating system on the HL-2A tokamak a remote communication system based on CAN bus technology is designed and realized. This network system uses a PCI board with a SJA1000 CAN bus controller and several TMS320F2812 digital signal processors as the host node and guest nodes respectively. Combined with a user interface program, the communication system can achieve the function of remote control of the PSM power supplies and hence improve its controllability and operation effectiveness.%为提高HL-2A装置辅助加热系统脉冲阶梯调制(PSM)电源的运行效率和操作可靠性，设计并实现了一种基于 CAN 总线技术的远程控制通信系统。该系统采用载有 SJA1000CAN 总线控制器的 PCI 板卡以及TMS320F2812微处理器分别作为上位机和下位机的通信终端，结合用户界面程序，实现了HL-2A受控核聚变装置辅助加热电源的远程控制，提高了其整体控制性能和操作效率。
