雷达波在线测流系统在屯溪水文站的应用

Application of radar online flow measurement system in Tunxi Hydrological Station

针对传统流量测验方式存在的自动化水平低、高洪流量测验困难、难以适应当前水文测验新形势等问题,屯溪水文站安装了定点雷达波在线测流系统。本文介绍了屯溪水文站定点雷达波在线测流系统的组成、工作原理、仪器安装等情况,同时对该系统的分析率定、误差分析、成果验证进行了分析。结果表明,雷达波测流系统在中高水时各项测量指标符合《河流流量测验规范》(GB 50179—2015)的要求,解决了中高水测验困难的问题,减轻了劳动力,提高了预警预报的时效性,可以在其他水文测站推广与应用。

In view of the low level of automation of traditional flow measurement methods,the difficulty of high flood flow measurement and the difficulty of adapting to the new situation of current hydrological measurement,the fixed-point radar wave online flow measurement system was installed in Tunxi Hydrological Station.This paper introduces the composition,working principle,instrument installation and analysis calibration of the fixed-point radar wave online current measurement system at Tunxi Hydrological Station.The conclusion shows that the indicators of radar wave flow measurement system meet the requirements of Code for River Flow Measurement(GB 50179—2015)at medium and high water measurement,which solves the difficulty of medium and high water measurement,reduces the labor force and improves the timeliness of early warning and forecasting.It can be popularized and applied in other hydrological stations.
