Virtual instrument testing system based on data acquisition equipment USB-4704 and LabVIEW

论文介绍了一种基于研华USB-4704数据采集板卡和图形化编程软件Lab VIEW的虚拟仪器测量系统,该系统实现了对薄膜压力传感器(Flexiforce Sensors A201)调理电路中电压信号的实时采集、处理、存储,从而可以有效的测量施加在薄膜压力传感器的法向载荷。测试系统主要由薄膜压力传感器、传感器调理电路、数据采集板卡USB-4704、应用开发软件Lab VIEW组成。

Paper introduced a virtual instrument testing system based on data acquisition equipment of Advantech USB-4704 and graphical programming software Lab VIEW. The system achieved the real-time collection, processing and storage of voltage signal from the conditioning circuit of the Flexiforce Sensors A201, which can effectively measure the normal load in the Flexiforce Sensors A201. Test system is mainly composed of Flexiforce Sensors A201, the sensor conditioning circuit, USB-4704, application development software Lab VIEW.
