文中以H-ADCP测流技术以及最小二乘法为基础,提出了在一定水位及指标流速范围下的回归方程拟合系统的系统结构。结合H-ADCP的特点及实际需求,以及。 NET开发环境设计开发了H-ADCP回归方程拟合及应用系统。系统根据H-ADCP采集的单元流速,通过函数计算得到指标流速。在不同的水位及指标流速范围下利用最小二乘法以及回归方程的计算与分析可以确定,H-ADCP的指标流速与断面平均流速的一元二次性关系,从而拟合出指标流速与断面平均流速的回归方程。结合相关系数选择合适的回归方程应用于流量的计算,借助指标流速与断面平均流速的相关系数分析进行推求相应的断面流量。系统的建设不仅给实际的断面平均流量的计算提供了有效方法,而且对测流及资料整编等方面提供了重要的技术支持。

Based on H-ADCP technology in flow measurement and least square method,propose a system structure of the regression e-quation system in a certain level and the index of the velocity range. Combined with the characteristics of H-ADCP and the practical needs,and the . NET development environment,H-ADCP regression equation fitting and application system is designed and developed. According to the H-ADCP acquisition unit flow and the function,the system obtains index velocity. It fits regression equation of mean velocity and cross section velocity index. The appropriate regression equation is selected by the correlation coefficient for flow calcula-tion. The system construction not only provides an effective method of calculating system construction to the actual average section flow, but also provides important technical support for the flow measurement and data compilation.
