船艇机舱综合模拟训练系统的设计研究

51卷第2期(总第190期)中国造船V ol.51 No.2 (Serial No. 190) 2010年6月 SHIPBUILDING OF CHINA June. 2010 文章编号:1000-4882 (2010) 02-0184-06 船艇机舱综合模拟训练系统的设计研究 余世林1,陈辉2,宁海强1,王术新1 (1.镇江船艇学院,镇江,212003; 2.武汉理工大学能动学院,武汉,430063) 摘要 从船艇机舱装备的使用管理要求出发,结合船队实际训练需要,吸收各种轮机模拟训练器研究的成功经验,综合运用虚拟技术、故障诊断技术和网络技术等,开发船艇机舱综合模拟训练系统。具体介绍了系统结 构、系统组成和功能、系统设计和实现方法,提出了一种集船艇机舱装备的操作使用和管理、监控报警、故 障诊断、虚拟维修、考核评分等功能的综合模拟训练系统。经实践证明,该系统功能全面,结构设计合理, 实现方法简便可行,可替代实船开展机电人员培训,效率高、周期短、成本低。 关键词:船艇机舱;综合模拟;故障诊断;虚拟维修 中图分类号:U676.4 文献标识码:A 0 引言 随着计算机软硬件技术、图形显示技术、通讯技术、人工智能等相关技术的发展,虚拟现实技术也取得了突破性进展,并广泛应用于军事、机械、建筑等领域[1]。利用虚拟技术开发的各种轮机训练模拟器、虚拟维修训练系统已应用于实际,取得了良好的使用效果。 船艇机舱设备复杂,涉及学科领域广泛;尤其在浅滩、大风浪等特殊工况下,管理要求高,故障诊断难度大,维修困难。因受装备条件、地理条件、气候条件等方面的限制,利用实船进行训练很难实施;这样就导致许多训练课目难以达到训练要求。因此,必须综合应用先进仿真技术、研制船艇机舱综合模拟训练系统、替代实装进行机舱综合训练、改善当前船艇机舱综合训练现状、丰富培训手段和方法、降低训练成本、提高训练效果,从而对培养高水平船艇机电管理专业技术人才,提高船艇机舱的综合保障水平具有重要意义。 1 系统结构和工作流程 1.1系统结构 船艇机舱综合模拟训练系统的结构示于图1,该系统的核心是实时仿真支撑平台,由支撑平台进行集中管理和调度各个功能子系统,实时反映各子系统的运行状态和训练过程。该系统主要由船艇机舱仿真系统、操作管理模拟平台、故障模拟系统、监控报警系统、虚拟拆装系统和考核评分系统组成。 收稿日期:2009-08-28;修改稿收稿日期:2010-04-26 基金项目:某总部科研项目(2007YY037)
