A multi-protocol network message association analysis and display method based on business chain

Abstract

The invention discloses a service-chain-based multi-protocol network message associated analysis and display method. To be specific, according to typical service characteristics and a flow of a powermonitoring system, equipment, communication links and all link communication protocols that are related to a service chain are identified automatically and thus a service chain is formed; an automaticassociation analysis is carried out on various communication protocols of all links of each service chain and execution information or operation states of all links is / are evaluated; and the execution information or operation states of all links is / are displayed and warned in a unfired manner at an interface by means of a service chain. With the method disclosed by the invention, the associated analysis and displaying of various communication protocols related to each service chain are realized; the service execution information of the transformer substation is displayed visually; and when anetwork becomes abnormal or the service is performed unsuccessfully, the problem link is located directly and thus the problem is handled quickly.

Description

Technical field [0001] The invention relates to a multi-protocol network message association analysis display method based on a service chain, and belongs to the technical field of network communication intelligent monitoring. Background technique [0002] In order to ensure the normal operation of the communication network, network message analysis equipment (such as network message analysis equipment) needs to be used in the smart substation to collect and analyze network messages in real time. The networking method is as follows figure 1 Shown. The network message analysis equipment accesses the IEC60870-5-104 (hereinafter referred to as 104) message of the dispatch telecontrol communication, the MMS message of the station control layer, the GOOSE message and the SV message of the process layer through the collection port. [0003] One of the main functions of the power monitoring system is to monitor and control primary equipment such as circuit breakers and isolation switches ...

AI Technical Summary

Problems solved by technology

Current network packet analysis equipment can perform real-time analysis and alarms on protocols such as 104, MMS, GOOSE, and SV. However, packet analysis mainly focuses on the analysis of the legality of the packet format of a single communication protocol. It is not intuitive, and it is impossible to display the operation status of the substation from the business level; and when the network abnormality occurs, there is often a large amount of alarm information, which is not conducive to the substation operation and maintenance personnel to quickly locate the problem link and troubleshoot the network fault
