Problems solved by technology

It is difficult for field maintenance personnel to analyze and locate faults efficiently only by relying on personal experience and knowledge, and it is necessary to rely on fault case information and the knowledge support of designers
Existing fault data are mostly stored in files or databases, but they cannot be effectively used for fault analysis and assist in the maintenance and support of avionics systems

Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The fault analysis method of avionics system based on graph database includes the following steps:

[0039] Step 1: According to the design information of the avionics system, abstract the avionics system architecture to generate a networked data model; and based on the data model, generate a graph database in the field of avionics architecture;

[0040] Step 2: According to the existing failure case data, summarize and summarize the typical failure modes; and establish the relationship between the failure cases, failure modes and architectural entities, and establish a graph database of avionics failures;

[0041] Step 3: Retrieve, query, count and ...

Abstract

The invention belongs to the technical field of avionics system maintenance and guarantee. The invention discloses an avionics system fault analysis method based on a graph database And the method comprises the steps of utilizing an avionics system design document and fault case data; creating a graph database according to the modeling method; according to the method, modeling definition is performed on an architecture entity, a fault mode, a fault case and a relationship respectively, and setting related attribute information to store system design knowledge and fault data, so that a retrieval function for query, statistics and interpretation can be conveniently created by subsequent applications, and the method is applied to interactive query of graph data to assist fault maintenance guarantee work of an avionic system.

Description

technical field [0001] The invention belongs to the technical field of avionics system maintenance and guarantee, in particular to an avionics system failure analysis method based on a graph database. Background technique [0002] Graph databases are typical non-relational databases, which represent and store data in a graph structure of nodes and edges. Nodes represent "entities" in the real world, and edges represent "relationships" between entities. Graph databases improve the description and retrieval capabilities of graph models by adding the concepts of attributes and labels. Compared with traditional relational databases, graph databases have a closer relationship between the logical model obtained from domain modeling and the original physical model of the domain, and are a natural way of expressing the actual existence of things and their relationships. In addition, graph databases are more scalable, and can naturally add new domain entities and connection relation...
