雷达波在线测流系统在群库勒水文站的应用分析

Application of radar wave online flow measurement system at Qunkule hydrological station

由于山区河流洪水流速大,涨落快,水流挟带大量漂浮物,采用常规水文测验设备抢测洪水耗时费力,也会对测验设备带来安全风险。雷达波在线测流系统是一种便于快速抢测洪水数据的非接触式测验设备,具有测验时间短、测验设备不被洪水漂浮物挂住等优势。通过对比分析用常规缆道流速仪与雷达波在线测流系统同步实测流量数据,从设备的稳定性和数据的误差分析可知:雷达波在线测流设备在群库勒水文站采集数据精度满足水文规范要求,测验过程中设备稳定性好,满足中小河流无人值守的自动化要求。

Due to the high flow velocity and rapid fluctuation of floods in mountainous rivers,as well as the large number of floating objects carried by floods,it is time-consuming and laborious to apply conventional hydrological measuring equipment to measure floods,which also poses a threat to the safety of the measuring equipment itself.The radar wave online flow measurement system is a non-contact measuring equipment that is convenient for quickly measuring flood data,with advantages of short measuring time and avoiding floating objects in floods.In this study,by comparing and analyzing the flow data measured synchronously by the conventional cableway current meter and the radar wave online flow measurement system,it can be seen from the stability of the equipment and the error analysis of the data,that the radar wave online flow measurement equipment has a higher accuracy and better stability in the data collected at Qunkule hydrological station,which meets the hydrological measurement specifications and the unattended automatic requirements of flow measurement in both small and medium rivers.
