【摘要】:LXI是以太網(wǎng)技術在儀器領域的拓展,是一種新型儀器總線技術,,它兼具GPIB、VXI、PXI等儀器總線技術的優(yōu)點,并結合了應用最廣泛的以太網(wǎng)技術,它的出現(xiàn)推動了自動測試系統(tǒng)向網(wǎng)絡分布式系統(tǒng)方向發(fā)展。本課題的主要任務是以LXI數(shù)據(jù)采集器為研究對象,設計并實現(xiàn)符合LXI規(guī)范的C類儀器。 本文首先介紹了測試總線的發(fā)展歷史和LXI總線技術的出現(xiàn),分析了數(shù)據(jù)采集系統(tǒng)的國內(nèi)外研究現(xiàn)狀,確定了本課題LXI數(shù)據(jù)采集器所要實現(xiàn)的功能和技術指標。其次,對LXI規(guī)范的關鍵技術和數(shù)據(jù)采集器的技術指標進行了詳細的分析。在此基礎上,提出了基于MSP430單片機的軟硬件設計方案。再次,根據(jù)總體方案,設計了LXI數(shù)據(jù)采集器的硬件平臺并調(diào)試。在軟件設計中,移植了TCP/IP協(xié)議棧,在嵌入式系統(tǒng)中實現(xiàn)了Web服務器,編寫了LXI儀器的內(nèi)置網(wǎng)頁,然后編寫了SCPI命令翻譯器,設計了LXI模塊間通信。最后,完成了CS8900A驅(qū)動程序設計以及數(shù)據(jù)采集功能程序設計。
[Abstract]:LXI is an extension of Ethernet technology in the field of instruments, is a new type of instrument bus technology, it has the advantages of GPIB,VXI,PXI and other instrument bus technology, and combines the most widely used Ethernet technology. It promotes the development of automatic test system to network distributed system. The main task of this paper is to design and implement C class instruments which accord with LXI specification, taking LXI data collector as research object. This paper first introduces the history of test bus and the appearance of LXI bus technology, analyzes the research status of data acquisition system at home and abroad, and determines the function and technical index of LXI data acquisition device. Secondly, the key technology of LXI specification and the technical index of data collector are analyzed in detail. On this basis, the hardware and software design scheme based on MSP430 single chip computer is put forward. Thirdly, according to the overall scheme, the hardware platform of LXI data collector is designed and debugged. In the software design, the TCP/IP protocol stack is transplanted, the Web server is implemented in the embedded system, the built-in web page of the LXI instrument is written, then the SCPI command translator is written, and the communication between the LXI modules is designed. Finally, the CS8900A driver and the data acquisition function are designed.
