Research On Scene Management System Of Navigation Simulator Based On Real Environment Field

Navigation simulators are widely used in the field of crew training and port and shipping engineering demonstration,and its simulation accuracy determines the effectiveness of crew training and the credibility of port and shipping engineering demonstration.The existing simulation scenarios of navigation simulators have three problems: natural environment settings,simulated traffic flow settings,and target ship operation are inconsistent with the real environment,and most scholars only conduct research on a single element,there are few researches on the overall conformity of the simulation scene with the real environment.To solve this problem,it is necessary to study the simulation scene of the navigation simulator.This paper takes the advanced architecture as the overall structure,and builds the scene management system of the navigation simulator based on the real environment field.The main tasks completed in this paper are as follows:(1)Analyzed the requirements of the navigation simulator scene management system.The system composition and work flow of the navigation simulator are described,which provides a foundation for the research scene management system.Combined with the simulation scene preparation process,the components of the environmental field are determined,and specific requirements are put forward for each component.(2)The key technologies supporting the realization of navigation simulator scene management system are analyzed.The environmental field model construction technology is determined to provide technical support for improving the authenticity of simulation scenes.A traffic condition matching method based on historical AIS data and a comprehensive control method of the target ship model were proposed to solve the problem of generating simulated traffic flow combining with real traffic flow and the problem of controlling and managing the target ship model movement after running(3)Designed the navigation simulator scene management system.The main functions and components of the system are determined,the components of the system are modularly designed based on the High Level Architecture,the data composition and structure of the system are analyzed,and the specific realization process of the system functions is planned.(4)The navigation simulator scene management system is implemented and verified.The system is based on the navigation simulator of Wuhan University of Technology,and the system interface is designed by referring to the layout of the coach station.The Yangtze River Estuary is taken as the test area,and the main functions of the system are verified by using real natural environment and traffic environment data.The research in this paper improves the authenticity of simulation scenarios of navigation simulators,reduces the amount of simulation scenarios for trainers,improves the effectiveness of crew training and the credibility of port and shipping engineering demonstrations,and realizes automation and intelligence for crew training and engineering demonstrations provides the foundation.
