A security-level display module graphic configuration simulation system and its simulation method

Abstract

The invention discloses a security-level display module graphic configuration simulation system and a simulation method thereof. The system includes an SVDU application simulation module, a board-level support package BSP and an SVDU hardware simulation module. The SVDU application simulation module is used to realize the "SVDU application" simulation. The board-level support package BSP and the SVDU hardware simulation module are used to provide simulation hardware and corresponding hardware interfaces for the SVDU application simulation module. The board-level support package BSP provides a function package for the upper-layer SVDU application driver to access hardware device registers; the SVDU hardware simulation module uses the intelligent continuous memory allocation technology to realize "SVDU hardware" simulation. The invention can realize that before downloading the graphic configuration, the graphic configuration simulation is carried out first, and the corresponding configuration effect is realized by simulating the actual hardware, so as to ensure that the graphic configuration effect meets the safety and reliability requirements of the nuclear power safety level.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a security-level display module graphic configuration simulation system and a simulation method thereof. Background technique [0002] The safety video display unit (Safety Video Display Unit, SVDU) is an important part of the safety digital control system (Digital Control System, DCS) of a nuclear power plant. Its main function is to provide the operator with received safety-related parameter information, At the same time, it supports the operator to send necessary control instructions to the relevant safety system through SVDU. Graphical configuration software is an important part of SVDU. In order to realize the functions of SVDU-related safety parameter display and necessary control command transmission, it is necessary to use graphic configuration software for configuration. [0003] SVDU belongs to the safety level in the nuclear power instrument and control system, and requir...

Problems solved by technology

At present, in order to ensure the safety and reliability of the configuration results, before the actual application, repeated unit tests and integration tests are carried out on the graphic configuration content. It is necessary to repeatedly modify, erase, and download the actual equipment, which will easily damage the equipment and shorten its life. Short, time-consuming and labor-intensive, inefficient

The current graphics configuration simulation in the industry is mostly used in the general industrial field, which cannot meet the safety, reliability, and accuracy requirements of the nuclear power field. However, many SVDU graphics configuration software in the nuclear power field are not equipped with simulation functions, and some graphics groups equipped with simulation functions The state method only supports part of the function simulation; or the operation is cumbersome and inconvenient to use; or the consideration of the actual hardware logic and the calculation performance verification are lacking after the Window computing kernel is adopted, and the simulation effect and speed are far from the actual requirements, etc.
