桂林电子科技大学本科毕业论文_基于LabVIEW的自动测试系统实验平台
Abstract
With the development of science and technology, the requirements of Electronic Measurement and Instruments is been more and more important, thus the Automatic Test System is emerged and is developing rapidly. Automatic Test System（ATS）is the main course in the major of measurement&control technology and instrumentation. The experiment of ATS includes software development&formation and is of great importance to theoretical study. The ATS experimental platform is based on Local area network, which makes equipments be shared in the terminal. In addition, the ATS experimental platform also saves the experiment cost as well as improves the efficiency.
To meet the needs of the experiment item of ATS，the ATS experimental platform is designed，based on the study of LabVIEW which is a kind of graphical tools and virtual instrument driver which is developed by VISA. It consists of hardware system and test software. The hardware system includes computer, gateway, GPIB instruments, VXI box & module and multi-functional Panel. The test software consists of virtual profile generator, virtual oscilloscope, virtual multimeter and some lab tests programs. As the tested objects, the multi-functional experimental board can be seted flexibly on the basis of different requirements. This platform accomplish measurements of AC or DC voltage, resistance, amplitude, frequency, cycle, phase and other basic parameters as well as experiment item. The test results show that it achieve the expected goals and can be applied to the Automatic Test System experiment.
