基于C8051F020单片机的虚拟仪器测试系统

Measuring System of Virtual Instrument Based on C8051F020 MCU

研制了一种新型的虚拟仪器液压与气动测试系统,该系统由数据采集子系统和数据处理分析子系统两部分组成。数据采集子系统以C8051F020单片机为核心,数据通讯处理分析子系统以VB6.0和MATLAB7.0为平台设计。两子系统通过标准RS-232C串口进行数据通讯。该虚拟仪器数据采集分析系统摆脱了虚拟仪器开发对LabVIEW等软件平台的依赖和PCI总线等数据采集板卡的束缚。

A new measuring system of virtual instrument is designed,which contains the subsystem of data sampling and the subsystem of data transacting and analyzing.The subsystem of data sampling has C8051F020 MCU as the core.The subsystem of transacting and analyzing is designed by VB6.0 and MATLAB7.0,communicating with the subsystem of data sampling through RS-232C serial part.The new system brakes away from the restrict of LabVlEW developing environment of Virtual Instrument.
