【摘要】 将飞机、舰船、战车等武器平台上的电子设备按照一定的协议联网加以有效综合,从而提高武器系统的作战能力已成为现代武器系统一个重要的发展方向。1553B总线标准是全球军事大国在这些武器平台综合化中广泛采用的通信标准。为此,开展了基于国内某研究所自主开发的1553B协议芯片的嵌入式1553B总线通信卡的设计与研究工作。论文的研究内容是:基于国内某研究所自主开发的1553B协议芯片设计嵌入式1553B总线通信卡。首先,论文系统阐述了1553B总线的基本知识,包括1553B总线的特点,1553B总线系统的组成,1553B消息传输的机制等。接着,针对设计需求,提出并论证了嵌入式1553B总线通信卡的设计方案。在此基础上,详细介绍了嵌入式1553B通信卡的软硬件设计。该板卡的硬件部分主要是嵌入式最小系统和1553B协议处理两大模块,最小系统的核心采用三星的S3C44BOX处理器,1553B协议处理部分的核心是1553B BCRTM芯片。软件部分主要包括S3C44BOX的U-boot移植,1553B BCRTM驱动和基本的嵌入式1553B总线通信卡测试程序的设计。最后,介绍了对所设计的嵌入式1553B总线通信卡进行总体联调和试验的情况,并对结果进行了分析。研究结果表明:以S3C44BOX处理器和1553B BCRTM为核心的嵌入式1553B总线通信卡的设计方案正确,设计完成的硬件满足1553B标准要求,为后续的软件为主的进一步开发打下了基础。更多还原

【Abstract】 It has become a significant development direction of improving combat capacity of weapon systems by means of integrating electronic devices on weapon platforms(such as the aircrafts,the ship,and the chariot and so on)in accordance with internet protocols. The MIL-STD-1553B is a widely-used communication standard among their integrated weapon platforms of global military powers.Based on the 1553B BCRTM developed by a domestic research institute,the research on 1553B bus communication board is presented in this paper.Firstly,the basic knowledge of 1553B bus,including its features,components and the transmission mechanism and so on,is described in this paper.And then,according to requirements of design,the design proposal of the embedded 1553B bus communication board is proposed and dcmonstratcd.The next is to introduce the design of the hardware and software in detail.The hardware mainly consists of two modules,one of which is the embedded system and the other is 1553B protocol processing system.The embedded system is mainly consisted of the Samsung’s S3C44BOX,and the 1553B protocol processing system is mainly made up of 1553B BCRTM.The software is composed of the U-boot transplantation of S3C44BOX、the development of the driver for 1553B BCRTM and the basic testing program for 1553B bus.In the end,some debugging situations is introduced about internet of embedded 1553B communication board with commercial board and the result is analyzed.The results of the research present that the design proposal of embedded 1553B bus communication board is correct.The hardware design meets the requirements of the 1553B standard.Based on this board,the further design can be carried out.更多还原
