Reverse self-organization signal flow chart generation method for control system of nuclear power plant

Abstract

The invention belongs to the technical field of DCS control of nuclear power plants, and particularly relates to a reverse self-organization signal flow chart generation method for a control system ofa nuclear power plant. The method comprises the following steps of (1) establishing a framework of a system; (2) collecting and processing data; (3) drawing a signal flow chart; and (4) connecting adesktop or mobile query service terminal with a network server, inputting a query signal, analyzing a request of the terminal by the server, returning a query result image or form, and performing display in the form of an overview chart and a detail chart in the terminal. The invention relates to integration analysis, relationship reconstruction and graphic display of DCS configuration data; the purposes of freely querying a signal flow topology relationship by a user, friendly displaying the topology relationship and performing state marking on a key link in the topology relationship are achieved; and especially for a functional drawing problem, when an important logic relationship is missing or omitted, remediation can be performed in time to avoid human errors.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant DCS control, and in particular relates to a method for generating a reverse self-organizing signal flow graph of a nuclear power plant control system. Background technique [0002] At present, nuclear power plants generally use the distributed control system DCS to realize the control of nuclear power plants, because the DCS system undertakes most of the control functions of the entire plant, the configuration data of the entire DCS system is very large, and the internal logical relationship is complex, which needs to be consulted when performing risk analysis With a large amount of drawing materials, it is a major difficulty to find the reference relationship between drawings. [0003] There are complex reference relationships in the DCS configuration data. Due to the limitations of the configuration software itself, there are also great limitations in viewing the link relationship be...
