摘要
介绍虚拟仪器技术及虚拟仪器程序设计的LabVIEW图形化集成开发平台、高精度数据采集卡PX I-6132在自动测试系统中用于数据采集程序的开发方法,以及利用PX I-6132数字I/O端口产生数字信号,实现对多路电源选择电路进行控制的实现方法和控制程序流程。实际开发证明,在LabVIEW开发环境下,利用PX I-6132可满足自动测试系统数据采集的需求,实现对多路电源选择电路的有效控制,缩短开发周期,提高开发效率。
Virtual Instrument technology and its development platform LabVIEW are introduced in the article. The development of a high accuracy data acquisition card PXI - 6132 is described. The digital I/O port is used to control the power selection circuit. Based on LabVIEW platform, PXI-6132 can meet the demand of data acquisition in the auto test system. And it can control the multi-path power selection circuit effectively. The development time is shorten as well as the efficiency is increased.
