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

Embodiment Construction

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following examples are used to further describe the present invention in detail.

[0040] "Network" in this article refers to a network-like interweaving relationship. For example, "network topology" refers to a distributed structure that extends like a network.

[0041] The meaning of "semantics" in this article is "meaning" or "meaning". Semantic model refers to a new type of data model that adds new data constructors and data processing primitives on the basis of relational model to express complex structures and rich semantics.

[0042] figure 1 It is an exemplary structural diagram of a method for determining a system model in an embodiment of the present invention. like figure 1 Said, the method includes the following steps:

[0043] Step 101 , establishing a network semantic model of a similar system of the target system according to the network topology...

Abstract

The embodiment of the invention discloses a method and a system for establishing a network semantic model of a target system. Wherein, the method includes: establishing a network semantic model of the similar system according to the network topology of a similar system of the target system; The semantic model is mapped to the initial network semantic model of the target system; and the initial network semantic model is corrected and verified according to the available information in the target system, and the verified network semantic model is obtained, and the verified network semantic model is obtained. The network semantic model of is used as the network semantic model corresponding to the network topology of the target system. The technical solution in the embodiment of the present invention can portablely and efficiently establish the network semantic model of the system application whose network topology cannot be obtained.

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 the wire is grounded, the line current will rise sharply and cause electronic equipment on the network, such as circuit breakers, to open. At this time, the key circuit breakers of the power supply network can be quickly found and turned off based on the network topology to reduce losses and protect other parts of the system. [0003] But in fact, the network top...
