Safety control knowledge graph construction method for whole process of electric power operation

Abstract

The invention relates to a safety control knowledge graph construction method for the whole process of electric power operation. The method comprises the following steps: firstly dividing collected information into dynamic data and static data based on a knowledge graph and a cause graph, and carrying out knowledge extraction; establishing an electric power event cause map by using four logic relationships; establishing a static knowledge graph; and finally, connecting the knowledge graph and the cause graph through a common entity. According to the invention, the relevance between people andequipment is utilized, dynamic and static relevance analysis is carried out, and the improvement of the safety control level of power operation is facilitated.

Description

technical field [0001] The invention belongs to the field of electric power operation safety management and control, and in particular relates to a safety management and control method for the whole process of power system operation based on a knowledge graph. Background technique [0002] With the expansion of power grid scale, power safety problems appear more frequently and the types of faults become more complex. The occurrence of safety production accidents will affect the normal operation of the equipment in the slightest, and cause personal injury or death in severe cases. [0003] The current security management and control methods, one is to rely on online and offline safety training for operators, and the other is to use target detection algorithms to conduct dress checks and identity authentication for staff. The current security management and control has the following problems: (1) Only the "both ends" of the operation are detected, and the security control of ...

AI Technical Summary

Problems solved by technology

The current security management and control has the following problems: (1) Only the "both ends" of the operation are detected, and the security control of the main body of the operation is lacking, that is, it is limited to monitoring the preparation work and aftermath work with target detection and face recognition , lack of risk assessment and correlation analysis of illegal operations in formal operations

(2) There is a lack of dynamic interaction analysis between people and equipment. Human-computer interaction is limited to monitoring the spatial distance of operators relative to live equipment, and the state detection data of live equipment often cannot be fed back to the operation site in time, and cannot assist relevant personnel in construction operations
