The virtual field system for the MASS mainly includes three sections: a numerical virtual scenario (including VR ship model and VR port model), a computing server (including core program, numerical ship model, and numerical port model) and a student operation console. The numerical ship model in the computing server can calculate the wave force, six degrees of freedom motion, etc., according to different ship types to simulate the actual attitude change of the real ship sailing on the water surface. The numerical port model includes the electronic chart data, shoreline mapping, tidal current grid map, and other parameters to simulate the operation of the ship in different waters.
The core program integrates the ship model and port model parameters, to provide real-time ship response calculation, and allows the autonomous ship developer to access the system through the Internet for data transmission. With the testing options provided by the program, including the built-in functions of the system or the control method pre-calculated by the user, the system can fully support the testing scenarios of various types of autonomous ships, create more convenient and rapid testing process to promote the domestic autonomous ship industry.
