specific Embodiment

[0059] 1. Variables and variable logical relationship extraction

[0060] Taking the interlocking data of our company as an example, the interlocking data of our company can be stored and viewed in text form, and multiple related files in the BOOL data package can be extracted through the python language to obtain the list of interlocking variables and the relevant attributes of each variable .

[0061] The key operation of interlocking variable relationship extraction is to figure 1 Interlocking logic expressions of the form convert to figure 2 The interlocking logical expression in the format, so that the logical expression including the relationship between and, or, and parentheses can be simplified into a logical expression with only the relationship between and, or, so that the logical expression relationship can be transformed into a two-level form. The first level is The OR relationship of multiple intermediate variables, and the second level is the AND relationship ...

Abstract

The invention relates to an interlocking logic relationship visual information processing method based on a knowledge graph. According to the method, an interlocking logic expression relation stored in a text file is read through a python language, a triad module is extracted, triads are variables, relations among the variables and variables, the triads are stored in a graphic database, and an interlocking logic relation graph database is formed and used for inquiring the interlocking variables and logic relations. Compared with the prior art, the mapping knowledge domain technology is used inthe railway signal industry for the first time and is applied to visual expression of the interlocking logic relationship in the interlocking system for the first time, and reference is provided forapplication of the interlocking system and other aspects of the railway signal industry.

Description

technical field [0001] The invention relates to a computer interlocking system for rail transit, in particular to a method for processing visual information of interlocking logical relationships based on knowledge graphs. Background technique [0002] The interlocking logic relationship is the core and most critical part of the computer interlocking system. In the industry, there has been no intuitive and visual representation of the complex interlocking relationship, which also reduces the comprehensibility and transparency of the interlocking relationship. The existing interlocking logical relationship query method is to search and analyze the logical expressions of the interlocking variables in the text file, which cannot comprehensively and conveniently query the logical relationship between the interlocking variables. Knowledge graph is an important branch of artificial intelligence technology. It is a graph-based data structure that conforms to human thinking mode and ...
