[0002] In the simulation model of the nuclear power plant design verification platform, the number of I&C system function diagrams is about 5,000 pages (taking Fuqing No. 5 and No. 6 power plants as an example). Due to the large number of function diagrams, the huge amount of signal transmission between drawings and frequent upgrade , so the simulation modeling of the I&C system is also the most time-consuming and labor-intensive part in the modeling process of the design verification platform

Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] The flow of the exemplary verification platform-based instrument control product file import modeling method of the present invention is as follows: figure 1 shown, including the following steps.

[0027] 1. Export the visio file of the functional diagram to a source xml file with a fixed format, and then perform format check and consistency check on the source xml file

[0028] DOM is the abbreviation of (Document Object Model), which is mainly used to establish a bridge between script and programming language, and is an application program interface for XML. DOM plans the xml data document into a document composed of multiple interconnected node levels. Each part in the document can be regarded as a derivative of Node, and the collection of nodes is regarded as a node tree (Tree).

[0029] Based on the DOM model, the mo...

Abstract

The invention, which belongs to the technical field of design verification of nuclear power plants, relates to a verification-platform-based method for inputting and modeling of an instrument-controlled finished product file. The method comprises the following steps that: step one, a function map visio file is outputted to be a fixed-format source xml file and then format checking and consistencychecking are carried out on the source format xml file; step two, consistency checking of the source xml file is not done successfully, a designer modifies the function map and then the step one is performed again; if consistency checking of the source xml file is done successfully, the source xml file is converted into a target xml file; step three, according to a visio mold library file, a control algorithm module library is created on a simulation platform; and step four, the simulation platform carries out sub-module division on a configuration drawing file and carries out automatic allocation on a drawing task number, and compiling down-loading of simulation sub modules is carried out to form an instrument-controlled finished product file. According to the invention, the method is implemented rapidly and accurately without human intervention. The verification-platform-based method is suitable for simulated modeling on various stack types of design verification platform instrumentcontrol systems.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant design verification, and relates to a modeling method for importing instrumentation and control finished product files based on a verification platform. Background technique [0002] In the simulation model of the nuclear power plant design verification platform, the number of I&C system function diagrams is about 5,000 pages (taking Fuqing No. 5 and No. 6 power plants as an example). Due to the large number of function diagrams, the huge amount of signal transmission between drawings and frequent upgrade , so the simulation modeling of the I&C system is also the most time-consuming and labor-intensive part in the modeling process of the design verification platform. [0003] The instrument and control product documents published in the past few years did not use the standard block design method to produce drawings, and the drawings did not meet the conditions for computer code analysi...
