【摘要】 自20世纪70年代前后开始起步并用于航海教育的计算机仿真教学培训设备——船舶操纵模拟器,无论在种类、功能及技术性能方面目前都处于一个崭新的阶段,在海员培训和适任评估中起着重要的作用。 航海是个国际性活动,同一海域有多个国家的船舶在航行并发生交互行为,对于不同国家地区的船员,他们的做法、技术水平或航行习惯有相当大的差异,能够理解对方的航行意图对于驾驶员来说是很重要的知识和经验,需要在实船上长期的学习积累。纵观各国的操纵模拟器训练系统,大都封闭独立,受训船员只能与同组学员进行船舶操纵互动练习,这与实际航行环境是不符的。 基于以上的考虑,我们从船舶操纵培训的国际化交互出发,向世界海事大学联合会(IAMU)提出“基于互联网的多船舶操纵模拟器集成”项目的研究申请并获得立项和资金支持。通过该项目的研究,建立基于广域网络的多操纵模拟器集成系统,将世界各地孤立的船舶操纵模拟器集成起来,通过网络的通信来实现相互之间的交互。 本文结合了Agent/多Agent系统技术,利用JADE开发平台,设计并基本实现了基于多Agent系统的多船舶操纵模拟器集成原型系统。主要完成的工作有:(1) 描述了集成系统的服务和约束,对本文要实现的集成系统进行了需求分析。针对系统需求,较详细的比较了目前可以采用的技术,对于基于互联网的船舶操纵模拟器集成系统所适用的技术路线进行了论证。(2) 基于航海操作的特性以及模拟器间交互信息的需要,设计并实现了一个多Agent系统中的本体库,该库中包含了交互信息所用到的船舶、船舶操纵模拟器、虚拟海域等各种对象数据的定义,保证了在整个集成系统平台上的知识共享。(3) 从系统结构设计出发,构建了该MAS中基本的Agent类型,主要有SHS Agent、Facilitator Agent、VHF Agent等,对它们之间的交互行为进行了详细的定义和设计,以及在本体的基础上定义了Agent间交互的数据格式。(4)定义和实现了模拟器端Agent与船舶操纵模拟器的接口,通过该接更多还原

【Abstract】 Ship-handling simulators, developed around the 1970s and applied to computer-simulative training in navigation education, assuming an important role in training and qualification evaluation of sailors, has entered a new development stage in terms of category, function and performance.Navigation is an international activity, with ships from different countries sailing and interacting with each other in the same maritime space. Sailors from different countries or regions differ substantially in their practices, techniques and navigational habits. Therefore, important as it is, to understand navigational intention of other ships requires plenty of practical experiences. Across the world, all the ship-handling simulators are independent, merely enabling trainees to carry out interaction practice with those in the same group even after the realization of interaction between multi-ownship in the local area network, which, of course, does not accord with real navigation environment.Therefore, we apply to International Association of Maritime Universities (IAMU) for the initiation of and financial support for the project of Internet Integration of Ship-handling Simulators Based on MAS, so as to establish such an integration system realizing integration of and interaction among all independent simulators across the world through Internet communication.Utilizing Agent/MAS technology and JADE development platform, this paper designs and basically implements a prototype integrated system of multi-ship-handling simulators based on MAS. Main accomplishments are listed as follows:(1) Describes services and restrictions of integration system, analyzes the requirements of the system, compares availabletechnologies based on the demand, and demonstrates the technology route of integration system of ship-handling simulators based on MAS.(2) Implements an Ontology Library of MAS based on properties of navigation handling and the demand for information interaction among simulators, which gives out definitions of ship, ship-handling simulator, virtual sea area and other object data to ensure knowledge sharing based on the system.(3) Designs and implements SHS Agent, Facilitator Agent, VHF Agent, and so forth to be basic agents in MAS, and provides the detailed definition and design for the interacted protocols among them, including the definition for format of interchanged data based on Ontology.(4) Defines and implements an interface between simulator terminal Agent and ship-handling simulator for information exchange. Develops a simple SHS system for testing and debugging in place of real SHS and to facilitate a two-dimensional interface reflecting the interaction at the disposal of system administrators.(5) Implements the communication among Agents through Internet, and tests the developed software.The realization of the integration prototype system will provide a platform for long-distance interaction between handling simulators. Meanwhile, international integration of handling simulator training will improve the factuality of ship-handling simulation and in turn substantially enhance the technical level and professional qualification of trainees.更多还原
