摘　　要：采用3个监测通道、局部符合逻辑、2级三取二表决、现场可编程门阵列和微处理器2种并行技术研制了绵阳研究堆全数字化保护系统。对该系统的可靠性分析结果表明,任何单一故障的出现,都不会妨碍其执行安全保护功能,拒动概率小于10-5。经过4年多的运行证明该系统满足绵阳研究堆的使用要求。The digital protection system of China Mianyang Research Reactor has been developed, which is based on the parallel processing of MCU and FPGA, three checking channels, the partial logical, double judge. The analysis of the system shows that it is reliable and safe, any single fault can not hinder the implementation of the system's safety function, and the failure probability is less than 10-5. It has been running for four years to prove that it meets the requirement of China Mianyang Research Reactor.
