【摘要】：MIL-STD-1553B是一种集中控制式、时分命令/响应型多路串行数据总线标准，具有互连简单、高可靠性和灵活性等特性，最早应用于航空机载系统设备的互联，现已广泛地应用于航空航天等领域，并逐渐在更广泛的领域中应用。在国内1553B总线应用已开展多年，随着GJB289A-97标准的推广普及，各种新型装备的设计普遍选用了1553B总线，对于已安装在飞机等装备上的1553B总线，要在设备外场进行调试和检查维护，还没有功能较全面、使用很方便的相关测试设备。本文的研究目标是采用当前流行的嵌入式计算机开发方法，设计一款完全符合1553B协议，可模拟仿真BC、RT和MT多种模式，满足设备外场测试使用要求的便携加固式1553B总线现场测试仪。论文首先介绍了1553B总线技术及其应用背景，分析了1553B总线系统在设计、使用过程中对测试设备的需求，针对外场测试的特殊要求，提出了该现场测试仪的硬件设计和软件解决方案。该测试仪的外形特征类似于一台加固型笔记本电脑，扩展了1553B总线连接接口。硬件设计采用子母板结构，，主板采用基于ARM处理器的S3C2440A核心板，扩展子板上设计了以BU-61580为核心的1553B接口模块，利用CPLD器件实现核心板与1553B接口电路的控制逻辑。软件设计上，采用嵌入式Linux操作系统，在S3C2440A主板上移植Linux操作系统内核和相应的BSP，在Linux下开发1553B总线专用应用软件，并设计开发应用测试人机界面；在完成整个测试系统的硬件、软件设计、调试后，结合应用实例，对设计进行了测试验证和现场试用，验证结果表明，该测试仪硬件系统运行稳定，软件运行正常，具有较大的实用价值，达到了预期的设计目标；论文最后总结了设计工作，并对1553B总线测试设备将来进一步的发展提出了展望。
[Abstract]:MIL-STD-1553B is a centralized control, time division command / response multiplex serial data bus standard with the characteristics of simple interconnection, high reliability and flexibility. Has been widely used in aerospace and other fields, and gradually in a wider range of applications. 1553B bus has been applied in China for many years. With the popularization of GJB289A-97 standard, 1553B bus is widely used in the design of various new equipment. For the 1553B bus, which has been installed on aircraft and other equipment, it is necessary to debug and inspect and maintain the 1553B bus in the field of equipment. There is no functional and easy to use related testing equipment. The research goal of this paper is to design a kind of embedded computer development method, which conforms to 1553B protocol completely, and can simulate many kinds of models of BCU RT and MT. This paper introduces the 1553B bus technology and its application background, and analyzes the requirements of the 1553B bus system in the design and use process. According to the special requirements of the field test, the hardware design and software solution of the field tester are presented. The shape of the tester is similar to that of a reinforced notebook computer. The 1553B bus connection interface is extended. The hardware design adopts the sub-motherboard structure, the motherboard adopts the S3C2440A core board based on the ARM processor, and the 1553B interface module with BU-61580 as the core is designed on the extension sub-board. The control logic between the core board and 1553B interface circuit is realized by using CPLD device. In software design, the embedded Linux operating system is adopted, the kernel of Linux operating system and the corresponding BSPs are transplanted on the S3C2440A motherboard, and the 1553B bus special application software is developed under Linux. After the hardware, software design and debugging of the whole test system are completed, the design is tested and tested with an application example. The verification results show that, The hardware system runs stably and the software runs normally, which has great practical value and achieves the expected design goal. Finally, the paper summarizes the design work, and puts forward the prospect for the further development of 1553B bus test equipment in the future.
