摘　　要：基于IEC60870-5-103规约和嵌入式ucLinux平台,设计了一种应用于电力系统保护测控装置的冗余网络通信方案。该方案在硬件设计上采用双以太网口,两个网口互为备用,在软件设计上利用嵌入式ucLinux系统中的socket编程和数据的共享或备份实现了保护装置针对多个上位机的冗余网络通信功能。对103规约的基本应用功能进行了分析,并针对冗余网络通信中应用功能遇到的特殊问题,提出了应用功能实现的方法。经过在保护装置中的应用,表明该方案能有效地提高通信的可靠性。This paper designs a scheme of redundant network communication based on IEC60870-5-103 transmission protocol and embedded ucLinux platform, which is applied to microcomputer-based relay protection devices. The scheme adopts a pair of Ethernet ports, one of which is the other’s standby in hardware design, and makes use of socket programming in Linux system and data sharing or backup to achieve redundant network communication aiming at several host computers in software design. The basic application function of protocol 103 is analyzed, and aiming at the special problem about the application function in redundant network communication, the solutions to the practice of application function are proposed. The application in protection devices indicates that the scheme can improve the reliability of communication.
