本文智能仿真平台依据HLA联邦设计思路设计,以时间运行框架(RTI)为基础,利用海洋环境成员、船舶属性模型解算成员、船舶自动识别成员等获取船舶航行时的海浪、风向以及船舶自身航行参数等基础数据,并将该基础数据保存至仿真数据库成员内;仿真导演台调取仿真数据库成员内的船舶基础数据,使用该仿真导演台内的管理控制模块和三维态势显示模块构建船体数学三维模型、三维实体模型和海洋环境三维场景后,使用三维视景显示成员为用户呈现船舶海上航行仿真三维仿真场景。实验结果表明,该仿真平台在运行过程中具备较强鲁棒性的同时,还可以有效模拟船舶在海上航行状况和升沉运动情况,应用效果显著。
The simulation platform is designed according to the HLA Federation design idea, based on the time operation framework (RTI), and uses the marine environment members, ship attribute model solving members and ship automatic identification members to obtain the basic data such as wave, wind direction and ship navigation parameters during ship navigation, and save the basic data to the simulation database members. After the simulation director platform retrieves the basic data of the ship in the simulation database members, uses the management control module and three-dimensional situation display module in the simulation director platform to build the ship mathematical three-dimensional model, three-dimensional solid model and three-dimensional scene of marine environment, and uses the three-dimensional visual display member to present the three-dimensional simulation scene of ship navigation simulation to the user. The experimental results show that: while the simulation platform has strong robustness in the operation process, it can also effectively simulate the navigation and heave motion of ships in marine navigation, and the application effect is remarkable.
