Water level data extension method, device, storage medium and equipment of river diversion outlet gate

Abstract

The present invention relates to a method, device, storage medium and equipment for water level data epitaxy at the gate of a river channel. The purpose of the present invention is to provide a method, device, storage medium and equipment for water level data epitaxy at the gate of a river channel. The technical scheme of the present invention is: a method for extending the water level data at the gate of a river channel, which is characterized in that: S1. Initialize a set support vector machine model, the set support vector machine model includes N individual support vector machine models, and the initialization content includes a set support vector machine model. The basic attribute information, adjustable parameter information and variable maximum delay information of the vector machine model; S2. During the monitoring period of the water level of the diversion gate, the relationship between the water level of the channel diversion gate and its associated elements is constructed based on the ensemble support vector machine model; S3, Simplify the ensemble support vector machine model; S4, in the period when the water level data of the diversion gate is missing, apply the simplified ensemble support vector machine model to carry out the extension of the water level data of the river diversion gate. The invention is applicable to the technical field of measurement and control.

Description

technical field [0001] The present invention relates to a method, device, storage medium and equipment for water level data epitaxy at the gate of a river channel. Applicable to the field of measurement and control technology. Background technique [0002] When the water in the river flows to the lower part of the terrain, it will break through the original shoreline under the action of floods or human activities to form a new distributary channel, and re-merge into the mainstream river downstream. After a long period of river bed evolution, the distributary channel may gradually develop or even replace the dominant position of the original channel, or it may gradually shrink or even cease to flow. Mastering information such as the water level at the mouth of a distributary channel is crucial to understanding the flow of the distributary channel and the evolution of the river bed. It also plays a very important role in river flood control, shipping, sewage outfall layout, a...

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.
