多模式船舶主机及其控制系统仿真器设计

The Design of Multi-Mode Simulators for Ship Engine and Its Control System

由上海海运学院研制的船舶主机及其控制系统仿真器有三种模式。第一种是单机模式,主机模型、控制系统及其操作界面都在一台计算机中。第二种是主从模式,上位机采用PC机实现人机操作界面,下位机采用单片机作为控制器通过模拟操作台实现对模拟主机的控制。第三种模式是网络模式,作为大型轮机模拟器的一个核心部分。主机模型采用基于动态优化的BP神经网络,控制系统的软件采用实时多任务操作系统。该仿真器已经在多所海运院校和企业用于学生和在职船员培训。

The Simulators for Ship Engine and its Control System, developed by Shanghai Maritime University (SMU), have three operation modes. The first mode is a single-computer system, in which both engine model and control system are simulated on one computer. The second mode is a distributed control system, in which the upper computer is a PC with human-machine interface, and the lower computer is a micro-controller to control the engine model through simulation console. The third mode is worked as a key part of the large marine engine room simulator developed by SMU. A dynamic optimal BP neural network is used as the engine model, and the software of control system is designed based on real-time multi-task operating system. The simulators have been used for training of students and seamen at several maritime colleges in China since 2000.
