Simulation Of Nabtesco ME Remote Control System

In this paper,the selection of content is based on the virtual simulation VLCC ship,the simulation system adopts the diesel engine which is MAN B&W 7S80ME-C9.2,the Main engine remote control system is M-800-V series produced by NABTESCO company.On this basis,and based on the related theory and the composition and characteristics of 7S80ME Electronic injection diesel engine,the control principle and the study of the main engine remote control system,we introduce the structure of the M-800-V in detail,complete the starting control logic,reversing control logic,parking control logic,load change and control of motor speed control logic of the M-800-V main engine remote control system.In order to intuitively understand the control logic of the system more clearly and simply,the simulation interface of the system logic control is designed and the running code is wrote to complete the remote control system of the diesel engine control function.Briefly describe the system structure and working principle of MG-800 governor which 7S80ME diesel engine,its core adjustment is the PID control.Based on the diesel engine steady state,according to the operation condition of diesel engine,the governor mathematical model,the actuator mathematical model and the diesel engine operating mathematical model is established,and then based on the established mathematical model,use the MATLAB simulation software,set up 7S80ME Simulink model of diesel engine speed regulation.Then we get the simulation curve of rotate speed about diesel engine under different conditions,after compared with the practical operation of the diesel engine,we know the accuracy of the simulation results of rotate speed.This article mainly in Visual Studio C#compiler environment,using its better graphics and powerful coding,design can be more realistic and operational functions of the simulation interface,graphics and the background code effectively combined,the virtual simulation system of the ship finally is completed.In this paper,the WPF tool is used to design the M-800-V pneumatic manoeuvring system of main engine remote control system,bridge operation panel and central control room operation panel.This article also design the bridge,central control room telegraph,and the different local telegraph;We complete the logical control of slow down and shut down of security and protection system about the main engine remote control system,according to its conservation project,I design the security system interface.
