Simulation System For Ship Navigate

In the prolegomenon, there mainly introduced the source, the research purpose and the significance of the project, the study states of domestic and international research and the framework of the thesis.In the second chapter, the basic technologies are introduced. First, it describes the conception of the three-dimensional graphic interface —OpenGL, interpretes it's design process, workflow, and the methods with VC compiling, and points out the key technologies and how to.implement these technologies. Second, the designing relevant programming knowledge has been expounded. It explains the computer simulation technologies, the computer visualization technologies, which has described the conception, characteristic and model separately.In the third chapter, it mianly introduced the mathematics models of the shipping driving. According to the design method and combining the basic shipping driving principle with the vision simulation technological, building up models, it has given the related formular, which is used directly in the system. The thesis primary interpreted the shipping propulsive force, shipping obstruction force, shipping manoeuvre and steady modeling especially, and interpreted the principle of PID control algorithm properly. It can calculate and draw the moving characteristic in real time, such as speed, acceleration and drinking water lines. Then it shows the results in the form of chart and export.In the forth chapter, the sequential system simulation technology is introduced. According to the characteristic of this system, it analysed the technology that the system needed to be used while realizing the real-time calculation. It explained thedifferential equation and the high precision calculation arithmetic-----Runge-Kutta,which is carried out in the detail design.The next two following chapters are overall design and detail design. It has explained the development environment from software and hardware respectively, It also expounds the basic function and the system data flow chart and work frame chart, then point out the items that should be paid attention in design, provided theexplanation the concept of the feedback results finally. In detail design part, implementation of the key method of function in detail and the key data structure are introduced.The last chapter summarizes the thesis and prospects the future work of the system. It explained the metrits and the defects, then given the following work notice problems and the next work to be developed.
