In the reactor control system prototype development of TMSR ( Thorium Molten Salt Reactor system , CAS) project, EPICS (Experimental Physics and Industrial Control System ) is adopted as Instrument and Con-trol software platform .For the aim of IOC ( Input/Output Controller ) redundancy and data synchronization of the system , the EPICS-based RMT ( Redundancy Monitor Task ) software package and its data -synchroniza-tion component CCE ( Continuous Control Executive ) were introduced .By the development of related IOC driv-er, redundant switch -over control of server IOC was implemented .The method of redundancy implementation using RMT in server and redundancy performance test for power control system are discussed in this paper .%在中科院钍基熔盐核能项目[1]（Thorium Molten Salt Reactor system， TMSR）的反应堆控制系统样机开发中，使用了EPICS （Experimental Physics and Industrial Control System ）[2]作为仪器与控制平台软件。为了实现控制系统的IOC （ Input/Output Controller ）级冗余及服务器间的数据同步，使用了基于EPICS环境的RMT（Redundancy Monitor Task）冗余软件包[3]及其数据同步组件CCE（Continuous Control Executive ）。通过开发相关的IOC驱动程序，实现了对服务器的IOC冗余切换控制。论文讨论了RMT冗余功能在服务器中的实现方法及在功率控制系统中的冗余性能实验情况。
