摘　　要：为了提高反应堆及其他高安全等级控制系统的安全可靠性,设计了一种基于Heartbeat软件和Autosave软件的EPICS IOC冗余测试平台。在此测试平台中,Heartbeat用于心跳监测,实现IOC的冗余切换;Autosave动态保存IOC记录的域到网络文件系统(NFS)服务器中,以实现数据同步。经测试,该系统运行良好,可快速实现IOC的冗余切换和数据信息同步。基于Heartbeat和Autosave的EPICS IOC冗余技术可在高可靠性等级控制系统得到进一步应用。With the purpose of improving the safety and reliability of the reactors and other control systems in high security level, the EPICS IOC redundant test plattbrm based on Heartbeat software and Autosave software has been designed. In this test platform, Heartbeat software is used for heartbeat monitoring, and implementing redundant switchover; Autosave software is used for dynamically saving the domains of IOC records into network file system（ NFS） server to implement data synchronization. The tests show that the system runs well, and quickly carries out redundant switchover and data information synchronization. Thus the EPICS IOC redundant technology based on Heartbeat and Autosave can be applied in control systems with high reliability level.
