摘 要:在水文测验过程中,起点距定位的准确性对流量测验精度至关重要。目前,常用的起点距定位方法在水文测验中存在诸多问题,如缆道计数器滑轮磨损影响精度、标志索人工读数误差大等问题。基于此,研究提出基于UWB技术的起点距定位方法;UWB是使用超宽带频率带宽的无线通信,主要特征是能够实现高精度定位,所开发的测验模块具有厘米级定位精度和几百米的测距范围。该项目研究成果在山路平、山里泉等水文站测试,测距精度符合水文测验规范要求;在丰收渠、引丹渠等农村河渠流量测验中试用,有效地提高了工作效率和测验精度。In hydrology tests,the accuracy of starting distance location is crucial to the accuracy of flow test.At present,there are many problems in the common starting distance positioning methods,such as the fact that wear of the cable counter pulley affects the accuracy,and the manual reading error of the marker cable is large.In this paper,a starting distance positioning method based on UWB technology is proposed.UWB is a wireless communication using ultra-wideband frequency bandwidth,and its main feature is that it can realize high-precision positioning.The developed module has centimeter-level positioning accuracy and a range of several hundred meters.The results of the project have been tested in the hydrographic stations such as Shandaoping and Shanchun,and the ranging accuracy is in line with the standard requirements.The experiment was conducted in the flow measurement of Fengshou Canal and Yindan Canal in rural areas,and the work efficiency and test accuracy were effectively improved.
