基于BU-64843的MIL-STD-1553B 总线远程终端的设计

Design of MIL-STD-1553B Bus Remote Terminal Based on BU-64843

摘要:

为了研究MIL-STD-1553B总线协议在某航空机载设备中的使用方法，提升1553B总线远程终端的性能，通过分析1553B总线的结构和特点，提出了采用DSP作为处理器，以BU-64843作为协议芯片实现远程终端（RT）的方案，并进行了硬件和软件的详细设计。相比传统以BU-61580为协议芯片的RT，简化了硬件设计，提高了数据处理能力。对设计的RT进行了1553B总线消息的接收、发送测试，结果表明其能够可靠地实现总线数据的传输，在高性能嵌入式设备的研制中具有一定的工程应用前景。

Abstract:

For the research on the methods of using MIL-STD-1553B protocol in a project, the structure and the characteristics of 1553B bus are analyzed, then a scheme which adopts DSP as the processor, using BU-64843 as the protocol chip for remote terminal is brought forward. Compared to the traditional BU-61580 as the protocol chip RT, which simplifies the hardware design, improves data processing ability. The test results show that the designed RT can receive and transmit reliably bus messages, thus it has certain engineering application prospect in the development of embedded equipment.
