Research Of Virtual Simulation And Intelligent Assessment On Marine Power Station And Load Based On Web3D

Marine power station is a necessary equipment for modern navigation education,which is placed in the rank of evaluated items by the Maritime Affairs Bureau of China. Considering the limitation of traditional evaluation, to develop the technology of the third generation and intelligent assessment system in the marine engineering simulator with new type and more functions should be strengthened. The development of virtual interactive simulation technology and internet technology makes it possible for the research advance of the third generation in the marine engineering simulator, Ship power station and load system is an important equipment in the ship and one of the most important parts in the marine engineering simulator.Therefore,it is of great significance to virtual simulation of marine power station and load system and intelligent assessment system.Objective to marine power station and load system, the virtual simulation modeling based on Web3D and research of the intelligent assessment system are established. The software schematic design of development model is achieved and the design of the third generation marine engineering simulator is created. The main research work shows as follows:In view of this, it is proved that using 3D digital modeling method to establish its external characteristic simulation, which was achieved in the MATLAB/Simulink software, the record data of the simulation was measured to realize the nested and communicated software between the net and database file, through the model interfaces, the database file can directly drive the three-dimensional virtual simulation model to achieve the fast, accurate and fidelity virtual simulation.And,the way of the building of the 3D modeling system in the marine power station and load system was put forward.Using VRML and Web3D technology to establish the modeling of the marine power station and load system,and using PHP+MySQL+Apache technology to project the database system based on B/S structure, both can prove the active and reality simulation be showed with embedded-interactive technology.Then,gives an example of modeling and virtual simulation of marine power station and load system based on Web3D to explain the process of the simulation.Finally, the database system and modeling system was used, the paper discusses several possible architectures of the intelligent assessment system with an expert system and an intelligent evaluation model based on Web3D platform. The virtual simulation of marine power station and load system and intelligent evaluation were established successfully. The main advantages of rich research results was obtained in the actually intelligent evaluation,The new achievements of studies and methods suggest some important principles and techniques for counseling practice to follow.
