Research On The Main Engine Starting System Of The Z-propeller Tug Driving Simulator

It is the key that marine power plant starts safely and reliably to ensure normal shipping. Among them, standing by engine before marine starting is the premise to marine power system normal starting. In order to ensure standing by engine successfully and normal shipping, all diesel engine starting systems set diesel engine starting simulation training system to train the operating accuracy of standing by engine and starting. Usually, diesel engine control system and simulation training system of ships share a set of instrument and operating switches. The switchover between simulation and practical operating is realized through a switch. At the same time, in order to train qualified seamen preferably, the kind of system for training seamen is established in shipping school and the center for seamen examination and training to reach the purpose of accumulating driving experience. However, z-propeller tug(hereinafter referred to as tug) bears to tow and emergency rescue for entering the port of ship acting as a harbor launch working in narrow fairway. Therefore, the requirements of driving operation ability are more stringent and it is needed to train concurrent operation of different positions of seamen at the same time. For this purpose, Power system for standing by engine and equipments of tug is realized operation training in spatial separation and time synchronization in this paper by using Visual Studio 2008, OpenSceneGraph(OSG), SQL Server 2000 and LabVIEW which can structure together the tug engine room scene established by Multigen Creator and the diesel engine model structured by Matlab/Simulink with data gloves and position trackers.In this paper, the implement method of the two standby engine environments operation process of the engine standing by of tug is discussed. 1. The virtual engine room established by Multigen Creator is entering by OSG. 2. The intrusive control to the hand wheel of turning gear, the valves of lubricating oil pump and air compressor, and the valves of fuel system, lubricating oil system and air system is realized by position trackers which trace the position and action of data gloves. 3. The controlled command of semi-physical platform and data gloves in virtual scene is received by ADO and is saved in the database. The simulation results of main engine lubricating oil system structured by Matlab/Simulink are saved in the database by communication protocol UPD. 4. The control instruction and the simulation results are output to human-computer interface on the semi-physical platform by using the communications Toolkit of LabVIEW SQL data to realize virtual real-time monitoring to fuel system, lubricating oil system and air system. The unity of time and space of standing by engine of tug is realized. The purpose of training different positions of seamen in the cockpit and cabin is also reached.
