River flood forecasting scheme construction method based on thematic knowledge graph

Abstract

The invention discloses a river flood forecasting scheme construction method based on a thematic knowledge graph. The method comprises the following steps: constructing a river forecasting thematic knowledge graph; inputting and analyzing the construction intention of the user; reasoning a river flood forecasting scheme; generation of a final forecast scheme. The method is efficient and accurate;the river system forecasting special knowledge graph can be used repeatedly after being constructed once, and when engineering in a river system changes, the changed engineering can be updated; according to the method, the river system flood scheme construction mode is flexible, and the river system flood forecasting scheme of any section in the drainage basin can be constructed as required. The method can be applied to various flood forecasting application systems and is not limited by programming languages.

Description

technical field [0001] The invention belongs to the technical field of flood forecasting, and in particular relates to a river system forecasting topic knowledge graph and river system flood forecast calculation, and specifically relates to a method for constructing a river system flood forecasting scheme. Background technique [0002] River system flood forecasting realizes the simultaneous flood forecast calculation of multiple sections in the basin. Compared with the flood forecast of a single section, the river system flood forecast needs to consider the topological relationship of each forecast section, because the forecast results in the upper reaches of the same river system will be different. If it has an impact on the downstream, the forecast calculation of the upstream section needs to be carried out first, and then the forecast calculation of the downstream section, so the construction and calculation process of the river system flood forecast is also more complica...

Problems solved by technology

[0004] The existing traditional manual method for the river system flood forecasting program to build corresponding software tools needs to deal with the relationship and attributes of various projects, and the corresponding development is difficult; the manual method for building the river system flood forecasting program has high requirements for staff and needs to be very skilled Master the relevant information in the river basin, and the construction of the scheme requires a large workload and is prone to errors, and it is impossible to verify the artificially modified river system flood forecast scheme; the existing river system flood forecast scheme construction method is not flexible and efficient enough, and cannot According to the actual flood control situation, a new river system flood forecasting scheme needs to be quickly constructed
