Problems solved by technology

[0004] There are obvious defects in the above method: Engineers need to master special XML language or logical expression writing technology when writing in XML language or logical expression, which has a high technical threshold, increases their mental load, and is prone to human error; in addition, Since XML files or logical expressions are stored in plain text files, there is no encryption feature
[0005] The above implementation methods, after the program is designed, generally can only be modified by experienced engineers, and it is difficult for users to modify the existing security functions according to new requirements

Embodiment

[0025] Such as figure 1 Shown, the method for state tree configuration of nuclear power plant key safety function based on visual model of the present invention, it comprises the following steps:

[0026] S1. Implement the module connection of the key safety function state tree by visualizing the basic logic modules, so as to realize the logical path of the key safety function state tree, the display and output of the result of the function state;

[0027] S2. Implement the logic in the basic logic module in a visual way;

[0028] S3. After the above steps are completed, a format can be output for storage and operation of the key safety function state tree;

[0029] The basic function module includes the path execution judgment logic of the key function state tree and the result display of the function state; the key safety function state tree includes reactor subcriticality, reactor core cooling, core waste heat discharge, reactor coolant system integrity, safety Shell inte...

Abstract

An object of the present invention is to disclose a method for configuring a critical safety function state tree of a nuclear power plant based on a visual model, compared with the prior art, Visual basic logic module is used to build the required state tree of key security functions. After you create the critical security feature status tree, the ability to store relevant state tree information in an encrypted format, Users only need to understand the functionality of the basic functional modules of visualization. According to the requirements, the required key safety function state tree canbe built and loaded into the system, thereby facilitating the development and confidentiality work, simplifying the development and maintenance work of the key safety function state tree, lightening the mental load of the configuration engineer, avoiding human error, improving the development efficiency, and realizing the purpose of the invention.

Description

technical field [0001] The invention relates to a method for configuring a key safety function state tree of a nuclear power plant, in particular to a method for configuring a state tree for key safety functions of a nuclear power plant based on a visualization model. Background technique [0002] With the continuous development of nuclear power plant digital instrument control system, the amount of information in the nuclear power plant instrument control network is also increasing. In order to help the operator obtain key information for monitoring and operating the power plant, it is necessary to use the information in the instrumentation and control network to display the key information required to the operator, so as to better support the operator to grasp the key status of the current power plant, which is unique to nuclear power plants The display of the key safety function status tree is one of the key display information in the main control room. [0003] In curre...
