【摘要】 本文将虚拟现实技术、计算机仿真技术、人工智能技术引入大型复杂装备维修训练，开发了大型复杂装备虚拟维修训练平台，为大型复杂装备维修训练提供了一种新的途径和方法。 本文在对大型复杂装备虚拟维修训练需求进行深入研究的基础上，以大型复杂装备维修训练过程仿真模型为切入点，结合HLA标准提出了大型复杂装备虚拟维修训练平台的新构想，构建了支持这一构想的通用性强的技术框架，对框架涉及的一些具体技术问题进行了深入研究，提出了基于MKDN(Maintenance Knowledge Description Net)的维修知识描述方法；建立了学生模型的评估数学模型；采用面向Agent的方法进行了系统设计；提出了一种柔性线缆建模的新算法。论文最后应用上述技术完成了某型导弹地测发控系统虚拟维修训练系统的开发。 论文主要研究内容包括： 一、首次从虚拟维修训练出发，对大型复杂装备虚拟维修的需求进行了全面的研究，不仅从宏观上对大型复杂装备虚拟维修系统的特点、需求进行了分析，而且还研究了电子、机械、液压等子系统和人体维修活动需求。 二、对大型复杂装备虚拟维修训练系统通用框架进行了研究。首先提出了单维修人员虚拟维修训练系统过程仿真模型，在此基础上结合HLA特点提出了大型复杂装备虚拟维修训练系统过程仿真模型和结构框架。建立了HLA联邦与虚拟维修训练的通用映射关系，提出了联邦成员结构和功能流程。 三、对大型复杂装备虚拟维修训练系统维修知识描述方法进行了深入研究，提出了基于MKDN的维修知识描述方法。MKDN是对Petri网的功能扩充，使其适合描述层次多、关系复杂的维修知识。文中对MKDN的定义、分析方法、基于MKDN虚拟维修想定建模、基于MKDN对象行为建模进行了深入研究，并证明了MKDN保持了Petri网的有界性、活性、安全性和可逆性。 四、对智能辅助训练技术进行了深入研究。采用面向对象基于框架的知识表示方法表示领域知识，将领域知识分为原理库和案例库，采用基于案例的推理机制，根据案例的相关原理属性，计算案例间相似度；通过建立学生模型的评估数学模型和评估指标体系，实现了对受训者的知识水平和维修能力的评估；根据学生模型确定了训练策略，控制实例模块选择补救的案例或新的案例对受训者进行训练，从而达到适人化训练的目的。 五、对面向Agent大型复杂装备虚拟维修训练系统设计方法进行了研究。将系统划分为维修训练Agent和虚拟样机Agent两大类进行设计，重点研究了维修训练Agent的设计方更多还原

At the last of the paper, the virtual maintenance training system of certain missile luaunch control system is developed with the above technologies.The main contents involved in this paper are:1. Firstly make a full-scale research on the requirement of large complex equipment virtual maintenance from the view of virtual maintenance training. Not only the characteristic and requirement of virtual maintenance training system are analyzed, but also the requiprments of electronic, mechanical, hydraulic sub-system and people maintenance action are studied in the virtual maintenance environment.2. Make the study on the general framework of large complex equipment virtual maintenance training system. Firstly put out the process simulation model of single maintenance man of the virtual maintenance training system, and based on which, the process simulation model and framework of large complex equipment virtual maintenance training system are put forward combim’ng with the characteristics of HLA. The general mapping relation between HLA federation and virtual maintenance training system is established, and the structure and flow of federates are given.3. Make the study on the maintenance knowledge description method in the large complex equipment virtual maintenance training system, and bring out a new description method based on MKDN. MKDN is realized through the function expansion of Petri Net which is suitable for describing the maintenance knowledge with many administrative levels and complex relation.更多还原
