摘要：
A plant protecting system is provided to improve reliability and operation performance by realizing perfect redundancy of a comparative logic control group and a simultaneous logic control group in a plant protecting system. A comparative logic control group(41) detects that a process variable reaches preset safety limit and outputs the state. A simultaneous logic control group(42) combines the trip state transmitted from another channel and the trip state of the own channel. An automatic test and associated processor(43) tests the soundness of the comparative logic control group and the simultaneous logic control group. A cabinet operator module(44) diagnoses the state of a nuclear protection system.
