【摘要】：当今计算机技术发展十分迅猛,各种各样的互联网技术被不断的应用到人们的日常生活中。与此同时,自动测试系统的发展也迎来了机遇,网络技术与自动测试技术的相结合正不断受到人们的关注。而自动测试标记语言(ATML)标准的出现正成为现在仪器测试领域的方向,该标准采用的是可扩展标记语言(XML)来对自动测试系统的测试信息进行标准化的描述。ATML标准引用的是IEEE1641协议中面向信号的测试需求,避免了传统自动测试系统面向仪器的弊端,让自动测试系统在走向通用化的道路上成为了可能。本论文重点研究的是在局域网中实现网络仪器的组建,开发基于ATML的面向信号的自动测试系统,把示波器、信号源、万用表这些仪器的IVI驱动提高到IVI-Signal驱动,并编写网络程序将仪器组建成自动测试系统。论文的主要研究内容为以下:(1)研究基于ATML标准的描述方法。ATML标准定义了一组信号组件的基本交换格式,用于表达对仪器设备被测对象的描述及测试结果等ATS相关信息,该标准能够提高测试系统软件的通用性和开放性,以及软硬件之间的交互的能力。(2)研究示波器、信号源等仪器驱动,并将这些仪器的驱动提升到信号级,把自动测试系统中原先的仪器控制命令转化为对测试信号需求的方法,从而实现更高层次的仪器互换。在面向信号的自动测试系统里面,各种测量仪器能够激发被测件模块以此使得测试数据可以呈现出来,所以,对仪器设备的驱动技术进行研究是必要的不可缺少的环节。(3)研究网络仪器的软件结构和需求,并使得能在网上颁布自己的能力和仪器功能。其中,最基本的功能为测试功能、输入输出功能、信息交换功能以及资源共享功能。编写软件识别仪器功能,并且让软件组建测试系统。
[Abstract]:With the rapid development of computer technology, a variety of Internet technologies have been continuously applied to people's daily life. At the same time, the development of automatic test system also ushered in an opportunity, the combination of network technology and automatic testing technology is getting more and more attention. However, the emergence of the (ATML) standard is becoming the direction of the instrument testing field. In this standard, extensible markup language (XML) is used to standardize the test information of automatic test system. The standard refers to the signal-oriented test requirement of IEEE1641 protocol, which avoids the shortcoming of traditional automatic test system. It is possible to make automatic test system on the way to generalization. This paper focuses on the establishment of network instruments in LAN, develops a signal-oriented automatic test system based on ATML, and improves the IVI driver of oscilloscope, signal source and multimeter to IVI-Signal driver. And write the network program to build the instrument into an automatic test system. The main contents of this paper are as follows: (1) A description method based on ATML standard. ATML-based standard defines a set of basic exchange format of signal components, which is used to express the information about ATS, such as the description of the object under test and the test result. This standard can improve the generality and openness of the test system software and the ability of interaction between software and hardware. (2) study the driving of oscilloscope, signal source and other instruments, and raise the driving of these instruments to signal level. The original instrument control command in the automatic test system is transformed into the method of demanding the test signal, and the instrument interchange is realized at a higher level. In the signal-oriented automatic test system, various measuring instruments can excite the module of the tested parts so that the test data can be presented, so, It is necessary and indispensable to study the driving technology of instrument and equipment. (3) to study the software structure and requirement of network instrument, and make it possible to promulgate its own capability and instrument function on the net. Among them, the most basic function is testing function, input and output function, information exchange function and resource sharing function. Write the function of the software identification instrument, and let the software set up the test system.
