The Research On Collaborative Training System Of Marine Engine Room Simulator Based On Internet

In recent years,with the development of international shipping industry and the progress of science and technology,and constantly improvement of the level of ship automation,large ships and fully automated ship operation difficulty increases,proposed to the ability of ship management personnel and technical personnel of the marine engine more stringent requirements.In addition,the Manila Amendment has made it clear to the engine room resource management as the mandatory standards of competency,and add the use of leadership and team work skills(operational level)and the use of leadership and management skills(management level)mandatory competence.The traditional marine engine room simulator software is used to simulate various systems in the engine room and equipment principle,which is suitable for single training and examination.It is difficult to use in teamwork training and have a lot of limitations.This thesis takes the cooperative training system of marine engine room simulator based DMS series VLCC marine simulator as the research object,completed following tasks mainly:1.To establish a centralized architecture based on C/S.The client realizes the cooperation training among users in the form of virtual ship.To analyze the Computer Supported Cooperative Work.To solve the inconsistency of the operation information transmission time sequence and the concurrent conflict in cooperative training.2.To design the database structure of collaborative training system,to build the user information database and virtual ship status file management database based on SQL Server 2012 database,accomplish database access by ADO.NET technology,to establish dynamic database of evaluation system,and to accomplish the conversion between ADO.NET and XML documents in dynamic database.3.To use network programming technology to realize the data communication between the server and the database,the server and the client,the client integrated management platform and the marine engine room simulator.To write the client and server program to achieve the start and stop control of the simulator,the dynamic management of the members of the cooperative group,the jurisdiction of the arbitration,the scene of the session,the status of the file upload and upload functions.
