The Research and Application of Discharge Algorithm Model in Natural River Course Based on 2D Flow Measurement

水文流量监测新技术在我国应用越来越广泛,但实用效果良好的系统较少。本文基于二维面上流速测量方式对流量算法模型做研究。从流量本身的特性,到流量相关参数获取,对二维测流方式下的流量算法模型进行了分析,包含指标流速法和传统流速面积法两种模型算法。该模型系统具有统一性的架构体系,标准化的数据接口,自主化的模型选择、实时性的参数校正,同时在实际应用过程中结合不同的应用场景进行了相关适应性研究。

The new technology of hydrological flow monitoring is more and more widely used in my country,but there are fewer systems with good practical effects.This paper studies the flow algorithm model based on the two-dimensional surface velocity measurement method.From the characteristics of the flow itself to the acquisition of flow-related parameters,the flow algorithm model under the two-dimensional flow measurement mode is analyzed.The model includes two model algorithms:the index velocity method and the traditional velocity area method.The model system has a unified architecture system,standardized data interface,independent model selection,and real-time parameter correction.At the same time,the model combines different application scenarios in the actual application process to carry out related adaptability research.
