基于虚拟仪器的多路电压测量的设计与实现

针对在电路测量中需要同时测量几处电压而没有足够的电压表、多点测量操作不便的问题,本文在利用虚拟仪器技术的基础上设计出了一种新型多路数字电压表。该多路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。其设计具有灵活性和可扩展性,有利于系统的集成。经过测试,该多路数字电压表性能稳定,能够很好的达到多路测量的目的。

Design and implementation of multi-channel voltage measurement based on the virtual instrument

Based on the measurement of the circuit does not have enough voltmeter and the inconvenience of multi-point measurement,based on the use of the virtual instrument technology designed on the base of a kind of new way more digital voltmeter.The more virtual digital voltmeter road in addition to data collection by DAQ realize outside,other functions are realized by software LabVIEW.The design has the flexibility and expansibility,be helpful for the integration of the system.Through testing,the digital voltmeter way more stable performance,can be good to achieve the purpose of multi-channel surveys.
