摘要： 本文利用Matlab设备控制工具箱,实现DGPS数据的导入与实时可视化,并用于ADCP断面走航观测。根据在舟山海域连续28 h的现场ADCP断面走航观测,该系统实时性较好,每秒钟更新1次航迹、当前船速与航向等信息,可满足实时可视化的要求。本系统的工作只需要准备1张导航底图,且操作简单、信号稳定,连续工作28 h均没有出现DGPS信号中断的情况。

关键词: Matlab, DGPS数据, 可视化, ADCP走航观测

Abstract: Based on the Instrument Control Toolbox in Matlab, DGPS signal data can be received via the serial port, so this technique can be used for real-time visualization in ship-mounted ACDP survey. The method was tested at Zhoushan sea area for 28-hour continuous ship-mounted ADCP observation. During the test, the real-time visualization system worked fine, tracks of DGPS, the speed of the vessel, and the direction of the vessel renewed automatically every second, which was satiable the requirement of real-time visualization. The only thing we need to do before the survey is to prepare one background map, the system is stable and is easy to use, and the most important, the system workes stably during the 28-hour observation.

Key words: Matlab, DGPS data, real-time visualization, ship-mounted ACDP survey
