【摘要】：MIL-STD-1553B(Military Standard 1553Bus)是以数字式时分制指令/响应型多路传输的数据通信总线而体现出来的,并通过数据总线终端或者数据总线子地址终端的接口组成。通常以分时传输的方式,实现系统中任意两个终端之间的信息传递功能。同时这种总线具有线性局域网络的结构、冗余容错能力、高水平电器保障性能和保证实时可确定性等特点,因此该总线已经广泛用于飞机综合航电系统、火箭和载人飞船系统,并进一步扩展到坦克、舰船、航天等其他领域中。MIL-STD-1553B总线服务于物理层和数据链路层协议上,1553B标准中规定了具备强大的64byte的消息交互能力,但是却不具备包含规定复杂的数据流应用在控制方法和存储容量等方面的大型数据结构中的功能,由于不支持更高层的通信服务方法,因此使得整个通信过程的传输效率低下。针对以上存在的问题,论文主要研究解决了:(1)循环冗余校验算法的改进,通过查表的方法避免了大量的移位运算,减少了处理器的运算时间,提高了运算效率;(2)通过对数据监视模块的设计,完成了把CDP(Common Data Packet)数据参数转换成多信息文本格式,从而改善了解析CDP参数的方法,可以动态的显示各参数的变换状态;(3)完成了对子地址终端的设置,提出了采用增加的三种变换规律来模拟仿真数据的测试;(4)设计完善数据结构体系和接口数据内容。1553B总线监视与仿真软件的开发以Visual Studio 2013开发平台为依托,使用MFC图形库作为设计主框架,采用了具有面向对象编程和泛型编程的C++语言为开发工具,在Windows操作系统上予以实现。软件完成了一个总线监视器、一个总线控制器和32个远程终端的主界面检测功能,实现了同时监测多个远程终端以及查看所有子地址消息内容的通信。研究人员可以在总线监视器下,对消息的内容进行查询和回放,也可以在总线控制器下对消息进行增加和修改,同样也可以在远程终端下对仿真状态、状态字和服务请求编码进行设置。论文还通过严格的测试用例对监视和仿真等核心功能进行了全面的测试,验证了该软件在仿真模拟1553B总线的通信功能中,具有友好的图形界面和良好的稳定性能。
[Abstract]:MIL-STD-1553B (military Standard 1553Bus) is composed of a digital time division instruction / response multiplexing data communication bus, which is composed of a data bus terminal or a data bus sub-address terminal. The information transfer function between any two terminals in the system is usually realized by time-sharing transmission. At the same time, the bus has the characteristics of linear local area network, redundant fault tolerance, high level electrical support performance and real-time certainty, so it has been widely used in aircraft integrated avionics system, rocket and manned spaceship system. And further extended to tanks, ships, spaceflight and other fields. MIL-STD-1553B bus serves the physical layer and data link layer protocol. However, it does not have the function of large data structure which includes complex data flow application in control method and storage capacity. Because it does not support higher-level communication service methods, the transmission efficiency of the whole communication process is low. In view of the above problems, the thesis mainly studies and solves the following: (1) the improvement of the cyclic redundancy check algorithm, which avoids a lot of shift operations and reduces the processor operation time by the method of table searching. (2) through the design of data monitoring module, the CDP (Common data packet) data parameters are converted into multi-information text format, and the method of resolving CDP parameters is improved. Can dynamically display the changing state of each parameter; (3) completed the setting of the sub-address terminal, Three kinds of transformation laws are proposed to simulate the test of simulation data. (4) the design and improvement of data structure system and interface data content .1553B bus monitoring and simulation software is based on Visual Studio 2013 development platform. MFC graphics library is used as the main frame of the design. C language with object-oriented programming and generic programming is used as the development tool. It is implemented on Windows operating system. The software has completed a bus monitor, a bus controller and 32 remote terminals' main interface detection function, and realized the communication of monitoring multiple remote terminals and checking all sub-address message content simultaneously. Researchers can query and play back the contents of messages under the bus monitor, add and modify messages under bus controllers, and also simulate the state of the messages at remote terminals. Status words and service request encoding are set. The core functions, such as monitoring and simulation, are tested by strict test cases, and it is verified that the software has friendly graphical interface and good stability in the communication function of simulation 1553B bus.
