基于网络RTK的水面流速流向测量系统研究

The Research on Measure System Regarding Current Velocity and Direction Based on Network RTK

本文详细介绍了借助网络RTK、单片机等技术开发的一种自衡式跟踪浮标测量系统。该系统在已知点上架设测量基站,利用GPRS无线网络实现对跟踪浮标的实时动态高精度定位。通过系统软件实时显示测量浮标及施测船舶位置,并可实时绘制成果图。该系统能自动测量出水流表面的流速、流向及纵横比降,不受通视、通航、天气状况等条件的影响,具有较强工程实用价值。

In this paper, it introduces a self-balanced observing buoy in details, which is on a basis of some technologies such asnetwork RTK, SCM, etc. It sets up basic station for measure through given points, and employs GPRS to locate an observing buoy precisely, timely and dynamically. By using system software, it is able to display locations of measuring buoys and ship, and timely generate related graphics. This system, which is not affected by intervisibility, navigation and weather conditions, automatically measure velocity, direction and aspect ratio of current surface. It has practical value for projects.
