Abstract


Marine Power Station Simulator is an important part of the engine room simulator, its students or crew training to enhance practical ability. With the rapid development of virtual reality technology, computer and network technology, Web-based simulation with its convenient, inexpensive, easy to upgrade and other advantages more and more users of all ages and in many at home and abroad have made the breakthrough. Turbine simulator, virtual reality technology not yet mature case for reference, to select ship power plant simulator for the study, designed to do the exploratory research. User to observe the three-dimensional images and real-time interaction through the Internet, because the data is not read from the local hard disk, the operating environment of the same traditional solutions only at the Web server to generate an image, and then a site to pass client due to network bandwidth limitations, this approach is difficult to meet the needs of the development of the online three-dimensional graphics. In this paper, three-dimensional scene of large-scale online virtual reality technology VRML (Virtual Reality Modeling Language), their interactions. The basic idea is: 1) making the cabin various mechanical and electrical equipment of the digitization of VRML vector three-dimensional model; 2) through the script interface to establish various mechanical and electrical systems control mathematical model, to drive three-dimensional virtual scene of action; 3) transmitted through the network model file After downloading a VRML browser on the local computer real-time rendering, interactive three-dimensional images and image animation. Subject to a 2700TEU container ship power station prototype VR (Virtual Reality) technology to produce a ship power station distribution panel and auxiliary diesel generator sets, emergency generators, shaft generator sets, three-dimensional visualization model using real mathematical model control of a three-dimensional scene, combined with multimedia such as sound, light, text annotation means of production of the Marine Engineering College of Jimei University Marine Power Station virtual operating system, and released by the Apache Web site on the Internet authentic reproduction of the ship power station simulation is the scene. Users anywhere login server, personal computer, to monitor for observation window, without the need for expensive special equipment (such as data gloves, helmet), only with the mouse and keyboard to control their own viewpoint and perspective on the whole virtual scene faceted browse and interact with the virtual scene dynamic roaming and real-time interaction. Introduced by means of supporting voice, text, video, image ship power plant system components, functions and operation of the assessment project, such as heavy-duty sound and light alarm, the cabin voice and the sound of the waves, seagulls . Some conventional operation steps are in the form of video and text hanging on a web page, the user can always see. Through the virtual scene database, the user can save all operation records, for teachers to check the operation of the user and the judge. System administrators and teachers Users can also be based on the actual situation anywhere online modification or production, to upload virtual scene and mathematical model, can also add various well wrl format virtual scene file and the mathematical model, the system has extended , functionality has stretchability.
