基于虚拟仪器的直流电压表设计

随着电子科学技术的发展,电子测量成为广大电子工作者必须掌握的手段,同时对测量仪器的精度和功能的要求也越来越高,而对电压量的测量要求更为突出。在参阅了大量前人设计的数字电压表的基础上,本文利用虚拟仪器技术构建了一个直流数字电压表。硬件设计采用DAQ体系结构并采用LabVIEW8.2软件平台进行软件设计。经过分析系统性能可靠,测试灵活,人机交互性强,可以达到测试者的要求。

Design of DC voltmeter based-on Virtual Instruments

With the development of electronic science and technology, electronic measurement becomes means which the workers must master. The accuracy and functional requirement have become more sophisticated, and the voltage measurement is highlighted. Based on a large number of previous digital voltage meter（DVM）, a DC DVM is designed used of virtual instruments, and which can achieve the requirements of the test with reliable performance、Strong human-computer interaction and flexibility test after being analyzed.
