The invention provides a buoy and method for measuring flow velocity and water level and drawing thalweg based on RTK. The buoy comprises a sealing spherical shell, a fixing support is arranged in the sealing spherical shell, an RTK measuring module is arranged on the fixing support, a positioning unit is arranged on the RTK measuring module, and the positioning unit is used for detecting real-time position information of the buoy. Forming a thalweg line; and the RTK measurement module transmits a signal to the RTK base station and feeds back water level information and flow velocity information. The sealed spherical shell made of plastic is adopted, the RTK measuring module is arranged in the sealed spherical shell, the floating track of the buoy is jointly determined by means of position information fed back by the positioning unit in real time and flow velocity and water level information detected by the RTK measuring module, the on-way flow velocity of the thalweg can be drawn while the thalweg of the river channel is drawn, and the measurement accuracy is improved. The problems that in the prior art, drawing of the thalweg needs pure manual work, the labor cost and the time cost are high, and the efficiency is low are solved.
本发明提供一种基于RTK测量流速和水位并绘制深泓线的浮标及方法,所述浮标包括密封球壳,所述密封球壳中设置有固定支架,固定支架上设置有RTK测量模块,RTK测量模块上设置有定位单元,所述定位单元用于检测浮标的实时位置信息,形成深泓线;RTK测量模块向RTK基站发射信号,反馈水位信息和流速信息。本发明采用塑料制成的密封球壳,密封球壳内设置有RTK测量模块,浮标的漂浮轨迹依靠定位单元实时反馈的位置信息、以及RTK测量模块检测到的流速和水位信息共同确定,既能在画出河道深泓线的同时,也能画出深泓线处的沿程流速,又能画出深泓线的沿程水位,解决了现有技术中深泓线的绘制需要纯手工、人工成本和时间成本较高、效率较低的问题。
