基于二线能坡法的自动测流系统设计与应用研究

Research on design and application of automatic flow measurement system based on two-lines energy slope method

主要研究了基于二线能坡法的自动测流系统的设计,并在小许庄水文站进行应用。该方法通过2台ADCP分别获取2条实测垂线流速,再通过实测垂线流速获取能坡参数,以流速～面积法计算断面流量。系统可以实现自动采集、储存、传输、实时在线查询和误差分析等功能,为实现"少人看管,无人值守"水文测站管理模式提供了条件。

Design of automatic flow measurement system based on two-lines energy slope method is mainly studied, which has been applied in Xiaoxu Village hydrological station. The method obtains two measured vertical velocity by two ADCP, then gets the slope parameters, and lastly calculates the section discharge by the velocity-area method. The System can achieve automatically collecting, storing, transmitting, real-time querying, error analyzing and other functions, which provides a condition for hydrological station management model of ＂few people care, no people on duty＂
