Indicating method and system for nuclear power plant back-up control panel

Abstract

The invention relates to an indicating method for a nuclear power plant back-up control panel, comprising the following steps of: S1, receiving an equipment control signal of a nuclear power plant; S2, carrying out logic processing on the equipment control signal to generate a logic processing result; and S3, outputting an indicating signal of the logic processing result. The invention also relates to an indicating system for the nuclear power plant back-up control panel, comprising a receiving module, a logic processing module and an outputting module, wherein the receiving module is used for receiving the equipment control signal of the nuclear power plant; the logic processing module is used for carrying out logic processing on the equipment control signal to generate the logic processing result; and the outputting module is used for outputting the indicating signal of the logic processing result. By adopting the indicating method and system for the nuclear power plant back-up control panel, provided by the invention, the comprehensive indicating function is realized, the reliability of a nuclear power plant operating function is improved, the equipment fault and the circuit fault are found out in time, the equipment failure operation rate is reduced and the safety is enhanced.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant operation, and more specifically relates to an indicating method and system for a control panel of a nuclear power plant. Background technique [0002] At present, in the nuclear power plants that adopt digital control system as the control method in the world, the computer-based control method is adopted. Although the digital control system adopts sufficient redundancy and has high reliability, there is still a problem of losing computerized control means. possibility. Therefore, the main control room of the nuclear power plant that adopts the computerized workstation as the main control method is generally equipped with a backup control panel. This backup control panel is equipped with hardware devices such as conventional indicator lights, alarm windows, and operation switches (with indicator lights). , in order to prevent immediate shut down due to loss of monitoring when the comp...
