基于MMG模型的船舶动态扇形自动搜寻模式

Automatic Search Mode of Ship's Dynamic Sector Based on MMG Model

为提高海上搜救效率,提出一种基于船舶操纵运动数学模型研究小组(Ship Manoeuvring Mathematical Model Group,MMG)模型的船舶动态扇形自动搜寻模式。在充分考虑风、流等外界扰动影响的基础上,不需要额外进行风、流等漂流模型的推算,以Matlab软件中Simulink模块为工具进行仿真。仿真结果表明:在不依赖GPS船位的前提下,船舶的航向、舵角、航速均符合航海实践要求。该搜寻模式可提高应对海上突发事故的搜救能力,从而减少突发事故中的人员伤亡和财产损失。

In order to improve the efficiency of search and rescue at sea,a dynamic search model of ship′s dynamic sector based on the maneuvering Modeling Group(MMG)model is proposed.This model is based on the consideration of the influence of external disturbances such as wind and flow.It does not need to extrapolate wind,flow,and other drift models,and it is simulated by using simulink module in Matlab software.The simulation results show that the ship′s heading,rudder angle,and speed all meet the requirements of navigation practice without relying on GPS position.The search mode can improve the search and rescue capabilities in response to accidents at sea,thereby reducing casualties and property losses in emergencies.
