【摘要】:隨著網(wǎng)絡(luò)技術(shù)持續(xù)高速的發(fā)展,一種新型的網(wǎng)絡(luò)化儀器總線技術(shù)LXI應(yīng)運(yùn)而生,LXI總線技術(shù)即以太網(wǎng)技術(shù)在儀器領(lǐng)域的擴(kuò)展。LXI技術(shù)自2005年提出以來(lái),各種多功能的LXI儀器已經(jīng)上市,隨著技術(shù)的發(fā)展,將會(huì)有越來(lái)越多的LXI儀器出現(xiàn)。 本文對(duì)LXI技術(shù)做了深入的研究,,在LXI的B類儀器中,需要支持IEEE1588精密時(shí)鐘同步協(xié)議。本文研究的LXI主時(shí)鐘模塊的核心功能就是實(shí)現(xiàn)LXI設(shè)備之間的精密時(shí)鐘同步,所以本論文的重點(diǎn)就在于研究IEEE1588精密時(shí)鐘同步協(xié)議的實(shí)現(xiàn)方法。 本文研究的內(nèi)容是基于FPGA的LXI主時(shí)鐘模塊。本論文從硬件與軟件兩個(gè)方面提出完整設(shè)計(jì)方案,并詳細(xì)描述了軟硬件實(shí)現(xiàn)過(guò)程。在硬件設(shè)計(jì)部分,硬件電路采用核心板和底板方式設(shè)計(jì)。核心板包括FPGA核心板和ARM9核心板,底板包括電源管理部分、核心板接口和LAN網(wǎng)絡(luò)通信部分。軟件設(shè)計(jì)部分,軟件包括FPGA IP設(shè)計(jì)和嵌入式Linux操作系統(tǒng)軟件設(shè)計(jì),前者主要完成硬件實(shí)現(xiàn)IEEE1588精密時(shí)鐘同步協(xié)議,后者主要完成LXI接口功能。 最后,本論文總結(jié)了基于FPGA的LXI主時(shí)鐘模塊的完成情況,并針對(duì)進(jìn)一步的研究提出了設(shè)想和計(jì)劃。
[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.
