摘　　要：虚拟测试场景在智能船舶评估中占有重要地位,数字孪生技术能够对现实环境进行描述、预测,实现智能现实环境与虚拟场景的交互映射。本文探索如何将数字孪生应用于智能船舶虚拟测试,构建船舶和环境数字孪生体来实现船舶在现实环境中如何获取数据、在哪获取数据,获取何种数据映射到虚拟测试场景中,并寻求更为准确的参数。初步构建出基于数字孪生的船舶虚拟测试场景架构,基于该架构进行虚拟测试前后以及船舶远程操作时延优化应用,该架构具有一定的有效性和可靠性。基于数字孪生技术能够提高智能船舶虚拟测试系统的效率和操作精度,增强实验结果的可靠性。Virtual test scenarios occupy an important position in the evaluation of smart ships.Digital twin technology can describe and predict the real environment and realize the interactive mapping of smart real environment and virtual scenarios.This paper explores how to apply digital twin to smart ship virtual test,constructs ship and environment digital twin to realize how and where the ship acquires data in real environment,what kind of data is acquired and mapped to virtual test scenes,and seeks more accurate parameters.Initially,a ship virtual test scenario architecture based on digital twin is constructed,based on which the application of virtual test before and after and ship remote operation delay optimization is carried out,and the architecture has certain validity and reliability.The digital twin-based technology can improve the efficiency and operation accuracy of the intelligent ship virtual test system and enhance the reliability of the experimental results.
