【摘要】：随着国内航空产业的不断发展,机载设备的研制受到了越来越多的重视,考虑到设备的安全性以及飞机供应商以及适航取证时间的影响,造成了航空机载设备研制周期长问题。因此在设备研制之初,根据系统研制周期,设备厂商都会采用模拟器的方式对技术的探索以及便于主机厂的系统接口的联调。本课题根据C919大飞机项目信息系统驾驶舱打印机研制项目产生,驾驶舱打印机是项目信息系统的重要组成设备之一,打印机通过以太网总线和429总线与外部系统交联。主要为飞机的机载航电系统(数据链系统,综合维护管理系统,飞行管理系统等)及机载信息系统成员设备(电子飞行包,文件服务器驻留的应用程序)提供数据打印数据服务。由于驾驶舱打印机的需求量少,投入资金多,收益慢等原因,国内并没有相关的企业负责研制驾驶舱打印机设备,国内相关的企业只负责为航空公司提供打印机所需要的耗材服务,其附加值并不高。而打印机设备的维修,售后服务等高附加值服务都被国外供应商占据。本论文研究的主要内容包括:论文首先介绍了驾驶舱打印机的相关背景,涉及到的技术协议,参考机载软件开发所采用的机载软件开发标准DO-178的定义了本软件开发模型,定义打印机模拟器设计开发过程中涉及到的需求分析,设计,编码,测试工作。其次,通过使用UML用例图的方式呈现软件需要实现的功能,软件的架构设计通过使用UML顺序图以及类图的方式表示。再次,软件的实现部分重点说明软件涉及到的主要代码部分。最后,测试部分通过使用专业的测试Parasoft C++Test工具对代码进行单元测试,通过手动方式实现功能测试。通过开发一款驾驶舱打印机模拟器软件,既可以基本满足驾驶舱打印机技术功能要求又可以为公司和企业节约研发成本,具有较高的工程应用价值。
[Abstract]:With the development of domestic aviation industry, more and more attention has been paid to the development of airborne equipment. Considering the influence of equipment safety, aircraft suppliers and airworthiness time, the development period of airborne equipment is long. Therefore, at the beginning of the equipment development, according to the development cycle of the system, the equipment manufacturers will adopt the way of simulator to explore the technology and facilitate the connection of the system interface of the host plant. According to the project of C919 aircraft project information system cockpit printer, cockpit printer is one of the important components of the project information system. The printer is cross-linked with the external system through Ethernet bus and 429 bus. It mainly consists of airborne avionics system (data link system, integrated maintenance management system, flight management system, etc.) and airborne information system member equipment (electronic flight package, etc.) File server hosted application) provides data printing data services. Because of less demand for cockpit printers, more investment and slow returns, there are no domestic enterprises responsible for developing cockpit printer equipment. Domestic enterprises are only responsible for providing printer service for airlines, and their added value is not high. And the maintenance of printer equipment, after-sales service and other high-value services are occupied by foreign suppliers. The main contents of this thesis are as follows: firstly, this paper introduces the background of cockpit printer, the technical protocol involved, and defines the software development model according to the airborne software development standard DO-178, which is used in airborne software development. Define the requirements analysis, design, coding and testing involved in the design and development of printer simulator. Secondly, the function of the software is presented by using the UML use case diagram, and the software architecture design is expressed by using the UML sequence diagram and the class diagram. Again, the software implementation part focuses on the software involved in the main part of the code. Finally, the testing part carries on the unit test to the code by using the specialized test Parasoft C Test tool, realizes the function test through the manual way. By developing a cockpit printer simulator software, it can not only meet the technical requirements of cockpit printer, but also save R & D costs for companies and enterprises. It has high engineering application value.
