1引言多功能传感器实验箱集各种被测体于一身,包含电容传感器、电感传感器、光电传感器、霍尔传感器、电涡流位移传感器、压阻式传感器、压电式传感器、温度传感器等功能。LABVIEW是一种图形化的编程语言,利用它可以方便地建立自己的虚拟仪器,为实现仪器编程和数据采集系统提供了便捷途径。LABVIEW支持NI公司的硬件,提供驱动程序库,但硬件价格相对较贵。但LABVIEW提供了CLF(CallLabrary Function Node)节点,使用户可以通过CLF节点调用外部的DLL动态链接库文件,从而解决了在LABVIEW环境中应用国产硬
1 INTRODUCTION The multi-function sensor experiment box integrates various measured objects, including capacitive sensors, inductive sensors, photoelectric sensors, Hall sensors, eddy current displacement sensors, piezoresistive sensors, piezoelectric sensors, temperature sensors and other functions. LABVIEW is a graphical programming language that makes it easy to build your own virtual instruments and provides a convenient way to implement instrumentation and data acquisition systems. LABVIEW supports National Instruments hardware, providing a driver library, but the hardware is relatively expensive. But LABVIEW provides CLF (CallLabrary Function Node) node, so that users can call external DLL dynamic link library file through the CLF node, thus solved the LABVIEW environment in the application of domestic hard
