基于Web的船舶操纵训练系统研究

Study on Web-based Shiphandling Training System

针对目前船舶操纵训练系统费用开支大、开发周期长、训练场地固定、训练人数和训练时间受限制的弱点,引入了Web仿真训练的理念,设计并实现了基于Web的船舶操纵训练原型系统,并对系统特征、体系结构、三维模型的建立与优化、系统交互等关键问题进行了研究。该系统依托Java构建体系结构开放、兼容能力强的Web三层体系模式的仿真应用,借助VRML营造交互、沉浸表现效果的虚拟船舶操纵训练环境,允许多用户随时随地的进行船舶操纵和决策等方面的学习和训练,从而为航海教育和培训提供了一种轻便灵活的学习平台。

Based on Web-based simulation theory, a prototype of the web-based shiphandling training system was designed and implemented, which aims at overcoming the weakness of high expenditure, long developing period and the limited accessibility of numerous marine simulation systems. The research focuses on the feature, architecture, 3D modeling, interaction and integration of this system. This system adopts Java to construct a web-based three-level architecture, which is open and strong compatible. The system creates an interactive and immersible virtual navigation world by using VRML. As a result, it allows many users to perform shiphandling and decision-making training online from anywhere, anytime. This training platform provides a portable and flexible training paradigm for maritime education and training.
