| The main engine remote control system is a typical complex system.Because of its complex structure and many modules,once there is a fault,it is difficult to judge and deal with it.The ship stops shipping and even has a major collision accident due to the fault of the remote-control system.Therefore,strengthening the training and training of the crew on the main engine remote control system is an important part of modern engine management.With the continuous development of ship control system,a variety of main engine remote control systems have emerged.Nabtesco main engine remote control produced in Japan is widely used in commercial ships because of its stable performance and convenient operation.In the existing marine simulation training system,the main engine remote control system is mainly Autochief 4 and ACC20,which has been unable to meet the training and training requirements of the host remote control system.In order to further improve the existing marine simulation training system,it is urgent to develop a set of Nabtesco main engine remote control simulation system suitable for training.First of all,in order to solve the problem that the main engine remote control system type of the existing marine simulator is not complete,this paper takes the RTA diesel engine propulsion system as the research object,aiming at the composition of the system and the requirements of the simulator main engine remote control system training program,using the modular modeling method,respectively established the Nabtesco main engine remote control system,the RTA48T-B main engine pneumatic control system and the propulsion device mathematical model.VC++is used to program and calculate the mathematical model,the simulation experiment shows that the simulation model can reflect the real-time change rule and control function of the actual system,and can meet the training requirements of the crew training institutions.Secondly,in order to further improve the existing visual operating environment of the marine simulator,by using VC++software development tools and unity3d engine,the visual operation interfaces of telegraph system,2D and 3D visual operation interface of Nabtesco main engine remote control system and RTA48T-B main engine pneumatic control system are developed.The simulation results show that the visual operation interface has low requirements for computer configuration,smooth operation,consistent with the actual system operation and display functions,It can dynamically display the real-time state changes of operators after various operations,so as to improve the effect of training and operation training;in addition,the visual operation interface can not only reproduce the phenomenon after failure,but also provide the visual operation environment for operators to troubleshoot,so as to meet the training requirements of troubleshooting and emergency operation;Finally,in order to realize the automatic evaluation function of the system,this paper studies the automatic evaluation reasoning algorithm.According to the requirements of the evaluation algorithm and related evaluation specifications,it compiles typical operation and troubleshooting test questions,and tests the test questions on the platform.The test results meet the requirements of the evaluation specifications and verify the correctness of the evaluation algorithm.The visual simulation system of Nabtesco main engine remote control developed in this paper realizes the automatic adjustment of interface size according to the change of display resolution;the simulation model can reflect the change rule of the actual system in real time,and can meet the training requirements of crew training institutions for crew members. |
