【摘要】：航空数据总线技术作为现代飞机电传操作系统和航空电子现代化的核心技术,决定着飞机的性能。近年来随着国内外网络技术、微电子技术和通信技术等飞速发展,航空电子系统也发生了巨大的变化。AFDX(Avionics Full Duplexes Switched Ethernet,航空电子全双工分组交换以太网)作为新一代航空电子系统发展的方向,得到越来越多的重视。它基于比较成熟的以太网技术,使得航电系统与地面通信更为简单,终端系统采用星型结构能级联多个子系统,并且彼此之间通信互不干涉,同时低成本、高速率、易扩充等特性使其得到更多领域的应用。本课题根据以上需求,设计了AFDX总线的ICD(Interfaced Control Document)管理软件,方便试验人员对总线上的数据进行解析和分析。具体来说,论文的主要工作总结如下:(1)本文首先概述了AFDX总线的协议标准、网络组成、数据结构和终端系统的通信原理;其次论述了ICD的组成、作用和功能模块划分;再次,设计了一款ICD软件,通过配置文件和数据库的操作,为总线数据解析和分析提供参考标准;最后,在ICD软件的基础上,设计了基于AFDX总线的ICD管理软件,二者通过数据的交互,可以实时准确的对AFDX总线上的数据进行接收、解析、分析、存储、发送等。本系统在Microsoft Visual Studio 2008环境下运行,ICD管理软件的编程语言为C#,AFDX总线管理软件以C++为设计语言,采用基于对话框编程技术设计出该系统。(2)本系统通过ICD软件数据的配置进行仿真试验和故障模拟注入,可以自动对AFDX终端子系统的通信状态进行判断,减少了试验成本和次数。另外本系统在设计过程中增加一个预留接口:报文类型,使得ICD管理软件能在其它领域取得应用。测试表明,该系统能够实时准确的解析和分析总线上传输的信息,并能够检测子系统的一些常规通信状况,具有抗干扰性强、扩展性好、应用前景广阔等特点。
[Abstract]:As the core technology of modern aircraft telex operating system and avionics modernization, aeronautical data bus technology determines the performance of aircraft. In recent years, with the rapid development of network technology, microelectronics technology and communication technology at home and abroad, Avionics Avionics full Duplexes switched Ethernet (avionics full Duplex switched Ethernet) has been paid more and more attention as a new generation of avionics systems. It is based on the more mature Ethernet technology, which makes the avionics system and ground communication easier. The terminal system can cascade multiple subsystems with star structure, and the communication between them is non-interference, at the same time, the communication is low cost and high speed. Easy to expand and other characteristics make it more and more fields of application. According to the above requirements, this paper designs the ICDX Interfaced Control document management software of AFDX bus, which is convenient for the tester to analyze and analyze the data on the bus. Specifically, the main work of this paper is summarized as follows: (1) this paper first summarizes the protocol standard, network composition, data structure and communication principle of terminal system of AFDX bus; secondly, discusses the composition, function and functional module division of ICD; thirdly, An ICD software is designed to provide the reference standard for bus data analysis and analysis through the operation of configuration file and database. Finally, the ICD management software based on AFDX bus is designed based on ICD software. The data on AFDX bus can be received, parsed, analyzed, stored and sent in real time and accurately. The programming language of this system running ICD management software in Microsoft Visual Studio 2008 is C#AFDX bus management software and C is the design language. The system is designed by using dialog programming technology.) the system can automatically judge the communication state of AFDX terminal subsystem by the configuration of ICD software data and fault simulation injection, thus reducing the test cost and times. In addition, this system adds a reserved interface in the design process: message type, which makes ICD management software can be applied in other fields. The test results show that the system can analyze and analyze the information transmitted on the bus in real time and accurately, and can detect some conventional communication conditions of the subsystem. The system has the characteristics of strong anti-interference, good expansibility and wide application prospect.
