Nuclear power plant safety level display device

Abstract

The invention discloses a nuclear power plant safety level display device, which comprises a human-machine input device, a graph and communication processing module, a power supply module and a display screen, and reserves a maintenance interface. The nuclear power plant safety level display device is applied in a nuclear power plant for providing various safety related parameter information related to a reactor protection system, a post-accident monitoring system and the like to an operator, and supporting the operator to send a control command to a related safety system through the device at the same time. According to the nuclear power plant safety level display device provided by the invention, through the manners such as adopting a simple system structure, selecting low-power consumption components and parts, and optimizing a network topology, the complexity of the nuclear power plant safety level display device is reduced, the power consumption of the whole device is reduced, and a connecting manner of the nuclear power plant safety level display device and a non-safety level system is more reasonable; through a method of combining off-line configuration and on-line running software, all static page processing is put in an off-line configuration part, the calculation processing load of the device is reduced, and the response speed of the device is improved.
