摘　　要：为满足EAST极向场超导线圈电源控制的高可靠性要求,结合电源控制网络的特点,采用双网热备份冗余技术进行可靠性优化,并改进了相应软件。对比分析了优化前后控制网络的可靠性,结果表明软硬件优化提高了系统的可靠性,满足了电源控制的高要求。To meet the extremely high reliability requirements in the power supply control network for the superconducting coils of EAST poloidal field, a double - network hot backup based on redundancy technology was applied and the software for the power supply control was improved. The reliability of the control network before and after the optimization was analyzed. Moreo- ver, the obtained results show that the reliability of the network was improved by optimizing which could meet the high require- ments of the power supply control.
