Digital backup panel for nuclear power plant

Abstract

The invention relates to a digital backup panel for a nuclear power plant. The digital backup panel comprises a security-level displayer, a security-level display processor, a non-security-level displayer and a non-security-level display processor. The security-level displayer is connected with a security-level field control equipment cabinet through the security-level display processor and used for displaying and processing security-level instrument control signals. The non-security-level displayer is connected with a non-security-level field control equipment cabinet through the non-security-level display processor and used for displaying and processing non-security-level instrument control signals. According to the digital backup panel, the digital displayer is adopted for changing the graphic display mode of an instrument control system in the traditional simulation technique, the equipment work state can be provided in a centralized mode, the overall occupied space is small, monitoring is centralized, the human-computer interface integration level is high, operators can look for monitoring targets conveniently, and the man-machine load is light. Meanwhile, the security-level displayer and the non-security-level displayer are arranged respectively, and therefore the independence of equipment operation between the security level and the non security level is guaranteed.
