Design And Research On Submarine Navigational Training Simulator Management Platform

With the progress of science and technology, more and more navigational training simulator is developed and used for sailing, space, etc. Submarine voyage training simulator is based on submarine movement simulation model, which combined with the ships of the manipulation of the specific process and the use of the computer system simulation technology, and simulate the use of the ships which can reproduce the rough seas, rudder, water, gas or rudder card and the other emergency control in different waters. As compared with the real training, the voyage training simulator has the high efficiency, low cost, small loss and high safety coefficient advantages.Navigational training simulator management platform is used to train personnel of submarine manipulate basic device, which ensure navigational training simulator can accurate simulation of the normal operation of submarine. Based on the navigational training simulator management platform as research object, the paper design and realize submarine manipulate dynamics simulation unit. Through researching the characteristics of submarine manipulate dynamics simulation unit with project situations, the system scheme of the unit is reasonably advanced in this paper. The system structure, the structure of infonnation flow exchanging with the outside devices of navigational training simulator test platform, the system model structure, the software structure are also built, the functional modules are achieved by VC++ and MATLAB mixing programming.The relatively rounded model calculation necessary to simulate motion of submarine are presented in this paper. By the study of ordinary differential equation for calculating methods and real-time simulation system simulation algorithm, the paper converts submarine space six degrees of freedom movement equation to submarine simulation execution equation, and the submarine spatial movement mathematical model is simulated.According to the program's request combined with the relevant technology of software engineering, the navigation training simulator management platform is designed, and network communication module, historical records and playback technology is also studied. The network communication is realized by adopting UDP communication protocol and using socket.Finally, this paper introduces the system test method. Based on the research of the basic software, according to the unit test, integrate testing, system testing, these three steps, combining with box testing, block box testing and performance testing method respectively. This paper tests every modules of navigational training simulator management platform. And it is proved that the navigational training simulator management platform can satisfy the system requirements.
