海上无线通信虚拟仿真实训平台建设研究

Rsearch on the Construction of Virtual Simulation Training Platform for Maritime Wireless Communication

为应对新冠疫情对实验教学的影响,并解决海上无线通信教学中存在海试实验危险性大、费用高、周期长等实际问题,本文将虚拟仿真技术融入实验教学,突破实验教学受地域环境、实验设备和安全因素等限制,设计了一种海上无线通信虚拟仿真实训平台。首先,本文阐述了平台建设目标与特色。其次,以“认知实验-典型系统实验-综合场景实验”为主线,详细介绍平台的功能模块。学生可从海上通信设备操作、海上通信系统设计和海上通信组网仿真进行实验。之后,本文介绍了基于3ds Max和Unity 3D相结合的平台开发关键技术。最后,本文分别介绍了三大实验模块的应用案例。该平台涵盖了海上无线通信学科相关课程实验,将为海洋信息人才的实践能力培养发挥积极作用。

In order to deal with the impact of the COVID-19 on experimental teaching,and solve the practical problems of high risk,high cost and long cyclein the sea trial experiments of maritime wireless communication,this paper has integrated the virtual simulation technology into experimental practice teaching,and designed a virtual simulation training platform for maritime wireless communication which break through the limitations of experimental teaching restricted by geographical environment,experimental equipment and safety factors.Firstly,this paper has expounded the construction objectives and characteristics of the platform.Then,this paper has introduced the modules of the platform in detail,which taking the“cognitive experiment-typical system experiment-integrated scene experiment”as the master stoke.Students can do experimental practice,which involve the operation of maritime communication equipment,the design of maritime communication system,and the simulation of maritime communication network.Then,this paper has introduced the key technologies for the platform development based on the combination of 3ds Max and Unity 3D.Finally,this paper has introduced the application cases of the three experimental modules separately.The platform has covered the experiments of maritime wireless communication courses,which will play an active role in cultivating the practical ability of marine information talents.
