Water level data extension method and device for river diversion port door, storage medium and equipment

Abstract

The invention relates to a water level data extension method and device for a river diversion port door, a storage medium and equipment. The invention aims to provide the water level data extension method and device for the river diversion port door, the storage medium and the equipment. According to the technical scheme, the method is characterized by comprising the steps that S1, initializing aset support vector machine model, wherein the set support vector machine model comprises N individual support vector machine models, wherein the initialization content comprises basic attribute information, adjustable parameter information and variable maximum lag time information of the set support vector machine model; S2, in a water level monitoring period of the diversion port door, constructing a relationship between the water level of the river diversion port door and associated elements thereof based on the set support vector machine model; S3, simplifying the set support vector machinemodel; and S4, in the water level data missing period of the diversion port door, performing river diversion port door water level data extension by applying the simplified set support vector machinemodel. The invention is suitable for the technical field of measurement and control.

Description

technical field [0001] The invention relates to a water level data extension method, device, storage medium and equipment of a diversion outlet gate of a river channel. Applicable to the field of measurement and control technology. Background technique [0002] During the flow of water in the river channel to the lower terrain, it will break through the original shoreline under the action of flood or human activities to form a new distributary channel, and rejoin the main stream channel downstream. After a long period of river bed evolution, the distributary channel may gradually develop or even replace the original channel's dominance, or may gradually shrink or even stop flowing. Mastering information such as the water level of the distributary channel mouth is very important for understanding the water flow movement of the distributary channel and the evolution of the river bed. [0003] Under the existing river hydrological monitoring system, there will be a phenomenon...

AI Technical Summary

Problems solved by technology

This method has a physical basis, and the calculation results are relatively accurate. However, its shortcomings are also very obvious, that is, it needs to collect the underwater terrain of the river channel, and the calculation performance is relatively high.
