【摘要】 对于国内各航空公司而言，维修工程直接关系到其生存和发展。长期以来，国内民机的维修信息管理工作主要停留在人工上，效率低，成本高，航空公司内部及各个航空公司间的维修资料航材、设备、维修经验没有很好的实现资源共享，而且对信息资源没有很好的信息处理系统，同时停机坪一线飞机维修故障排除工作存在信息需求量大与处理效率低之间的矛盾，从而导致航班经常性的延误，造成机队整体飞行可靠性不高。 在参照美国军方最新提出的飞机维修数字化技术方案，针对国内民机维修信息管理中存在的问题，结合中国东方航空武汉有限公司的具体工程需求与实践，本文提出一种新的民机维修信息支持系统——数字化综合维修支持信息系统。该系统将计算机网络、数据库、通信工程、软件工程等技术有机结合，首先用Internet／Intranet技术构建企业局域网，然后将飞机维修最原始的资料——维修手册电子化录入到主机系统，达到在各终端的快速信息访问，并针对停机坪维修的特点，将有线网进行延伸，在机场搭建基于无线局域网技术的便携式飞机维护助手PMA，提高飞机的故障排除速度与派遣放行率。最后在此基础上，开发维修部门内部各单位的综合信息处理系统以对维修行为与决策提供信息支持。 本论文研究了多层应用体系结构在开发基于Internet／Intranet的企业信息系统中的应用；探讨了网络数据库访问技术；简析了代理服务器与网络安全技术；利用无线局域网可灵活延伸的优点解决企业局域网的特殊区域延伸与高成本的问题。针对很多企业开发Web应用方面遇到的专业“瓶颈”——网页制作的高度专业性和不普及，利用Office软件建立基于Web的Intranet网络，研究了应用OFFICE实现客户端一般应用开发。最后，应用SOL SERVER，ACTIVEX和ASP的集成开发了一个维修信息综合管理系统——航材网上管理系统。更多还原

【Abstract】 To most of domestic airlines,the maintainance engineering is concerned to their survivals and development . For long times ,most of the airlines are still in the primitive stage of manual management on maintenance information.Especially in the work of troubleshooting on the civil aircraft ,there are difficulties of efficient engineering information support in the field of the airport .Therefore, the delays of the flights always happen ,and it cost big loss of money to the airlines.Referring to the newest proposal on aircraft maintenance of the military of U.S.A and aimming at the problems of the information management system of traditional civil aviation maintainence engineering, this thesis came up with a new system - digital integrated maintenance and support information system (DIMSIS), which is made up by the technologies of computer network, database, communication engineering, software engineering and etc.After its building,most of the requirements of the domestic airlines on information technologies will be met.Based on the case of the practice in China Eastern Airlines Wuhan Limited, this thesis firstly studied several layers application model on Intranet of enterprises development. In the model of DIMSIS, three layers application model on network was used, including the three layers form of Client/Server constructure ;then the access technology of database on Intranet network was analyzed; meanwhile, the proxy server technology with the security technology of the networks was studied.Following these items , the technology of Wireless Local Area Network was put forward and the possibility of it was discussed. At the end of this thesis the information management system of spares of civil aviation based on SQL server ,Active X and ASP technology was developed.更多还原
