Abstract

A value-taking analysis method for a default value of a signal of a nuclear power station control system, and a terminal device. The value-taking analysis method comprises: acquiring at least one preset default value of a target signal, and failure association data capable of representing actions correspondingly executed by a control system after the target signal fails (S10); on the basis of the failure association data, performing influence degree analysis processing on each preset default value, so as to obtain a discovery difficulty score, an influence degree score and a redundancy degree score (S20); and on the basis of the discovery difficulty score, the influence degree score and the redundancy degree score which correspond to each preset default value, determining a total score corresponding to each preset default value, and determining a settable default value of the target signal on the basis of all total scores (S30). The value-taking analysis method and the terminal device can help a worker to rationally evaluate the rationality of each preset default value of a control signal, and recommend the most rational default preset value to the worker as a recommended value of a default value.
