摘　　要：为解决实验室建设中成本高、技术更新慢及维护等方面的困难,适应现代测量仪器系统发展的要求,本文在分析数字电压表原理的基础上,利用虚拟仪器技术设计了一种新型数字电压表。虚拟数字电压表除数据采集由DAQ实现外,其他功能均由软件LabVIEW实现。其设计具有较高的灵活性和可扩展性,有利于系统集成。经测试,此数字电压表性能可靠,能达到测试者的要求。To resole the difficulty of high cost , slow technical renovation , maintenance and etc in lab construction and to adapt to the develop trend of measuring instrument, a new type of digital voltage meter is designed based on Virtual In- strument technology in the paper through studying the principle of digital voltage meter. The functions are achieved by LabVIEW in addition to the data acquisition completed by DAQ. The virtual digital voltage meter has high flexibility and scalability and system integration. Testing in laboratory verify that the performance stabilization of this meter is dependable. It can achieve the requirements of the test.
