Establishment method and system of network semantic model of target system

Abstract

The embodiment of the invention discloses an establishment method and system of a network semantic model of a target system. The method comprises the following steps: establishing the network semanticmodel of a similar network according to the network topology of the similar network of the target system; mapping the network semantic model of the similar system as the initial network semantic model according to a mapping rule between the target system and the similar system; and modifying and verifying the initial network semantic model according to the predicable information in the target system to obtain a verified network semantic model, and taking the verified network semantic model as the network semantic model corresponding to the network topology of the target system. Through the technical scheme disclosed by the embodiment of the invention, the network semantic model which cannot be obtained by the network topology and is applied by the system application can be portably and efficiently established.

Description

technical field [0001] The invention relates to the field of system model construction, in particular to a method and system for establishing a network semantic model of a target system. Background technique [0002] At present, some network applications work based on their own network topology, such as network routing optimization, system network fault location and other applications. For example, in the fault location and recovery of the system, the loss of the system can be minimized based on the network topology. Taking the power system as an example, wire grounding is a common fault in the power system. When a wire is grounded, the line current rises sharply and trips electronic devices on the network, such as circuit breakers. At this time, key circuit breakers of the power supply network can be quickly identified and shut down based on the network topology to reduce losses and protect other parts of the system. [0003] But in fact, the network topology of some net...

Problems solved by technology

The original network topology map corresponding to the water network distribution system may be cut off by the on-site construction workers without accurate WDS information due to unfavorable preservation, changes during the construction process, or failure to obtain it. This will affect life and water supply in that area

[0004] At present, for system applications where the network topology cannot be obtained, the network topology can only be manually determined by experts in the field or experienced system operators after reasoning based on the background information collected during on-site inspections.

When the network topology changes, the work needs to be done again, which is inefficient
