Security knowledge graph construction method and system for smart power plant

Abstract

The invention discloses a safety knowledge graph construction method and a system for a smart power plant. The method comprises the following steps: firstly, collecting data and constructing a knowledge model, and classifying, cleaning and storing the data according to the knowledge model; performing knowledge extraction on the unseparated data of the entity, and constructing a knowledge graph by using a knowledge extraction result and the separated data of the entity; and finally, applying the constructed knowledge graph to different scenes. The invention further discloses a system using the method. Compared with the prior art, the knowledge extraction method based on the features can perform entity extraction more accurately, and relationship extraction can be performed more quickly and accurately by encoding entities and sentences and utilizing a CNN method. The knowledge graph constructed by the invention comprehensively considers the current application situation and demand of safety management of the power enterprise, can effectively reduce the safety risk of the production link of the power plant, is convenient for the enterprise to realize intelligent management in power production, and guarantees the production safety of the power plant.

Description

AI Technical Summary

Problems solved by technology

For example, the safety responsibility management system is not perfect, the safety awareness of the staff is not strong, and the specific responsibility requirements of the post are not clear, etc.

These problems not only affect the safe production of electric power enterprises, but also pose a certain threat to the personal safety of staff.
