基于USB接口与LabVIEW的数据采集系统设计
Design of Data Acquisition System Based on USB Interface and LabVIEW
【摘要】 设计了基于USB接口与LabVIEW的数据采集系统。单片机将采集到的信号通过USB接口与串口间的桥接控制器——PL2303传输到PC机,通过LabVIEW进行分析处理。整个系统分为数据采集和数据处理2部分。实验证明,系统能实时精确地显示单片机采集的信号。
【Abstract】 A data acquisition system based on USB interface and LabVIEW was desig ned.Utilizing the USB to serial bridge controller——PL2303 chip,the data collected by MCU is transmitted to PC,then analyzed and processed by LabVI EW.The whole system is composed of two parts:one is data acquisition and t he other is data processing.The experiment proves that the system can displ ay the signal acquired by MCU precisely.
