【摘要】：随着网络技术持续高速的发展，一种新型的网络化仪器总线技术LXI应运而生，LXI总线技术即以太网技术在仪器领域的扩展。LXI技术自2005年提出以来，各种多功能的LXI仪器已经上市，随着技术的发展，将会有越来越多的LXI仪器出现。本文对LXI技术做了深入的研究，，在LXI的B类仪器中，需要支持IEEE1588精密时钟同步协议。本文研究的LXI主时钟模块的核心功能就是实现LXI设备之间的精密时钟同步，所以本论文的重点就在于研究IEEE1588精密时钟同步协议的实现方法。本文研究的内容是基于FPGA的LXI主时钟模块。本论文从硬件与软件两个方面提出完整设计方案，并详细描述了软硬件实现过程。在硬件设计部分，硬件电路采用核心板和底板方式设计。核心板包括FPGA核心板和ARM9核心板，底板包括电源管理部分、核心板接口和LAN网络通信部分。软件设计部分，软件包括FPGA IP设计和嵌入式Linux操作系统软件设计，前者主要完成硬件实现IEEE1588精密时钟同步协议，后者主要完成LXI接口功能。最后，本论文总结了基于FPGA的LXI主时钟模块的完成情况，并针对进一步的研究提出了设想和计划。
[Abstract]:With the continuous and rapid development of network technology, a new type of networked instrument bus technology (LXI) has emerged as an extension of Ethernet technology in the instrument field. Since 2005, a variety of multifunctional LXI instruments have been put on the market. With the development of technology, more and more LXI instruments will appear. In this paper, the LXI technology is deeply studied. In the LXI class B instrument, it is necessary to support the IEEE1588 precision clock synchronization protocol. The core function of the LXI master clock module studied in this paper is to realize the precision clock synchronization between LXI devices. Therefore, the emphasis of this paper is to study the implementation method of IEEE1588 precision clock synchronization protocol. The main LXI clock module based on FPGA is studied in this paper. This paper presents a complete design scheme from two aspects of hardware and software, and describes the implementation process of hardware and software in detail. The core board includes FPGA core board and ARM9 core board, and the bottom board includes power management part, core board interface and LAN network communication part. The software includes FPGA IP design and embedded Linux operating system software design. The former mainly completes the hardware implementation of IEEE1588 precise clock synchronization protocol, the latter mainly completes the LXI interface function. Finally, this paper summarizes the completion of LXI master clock module based on FPGA, and puts forward some ideas and plans for further research.
