多类型多通道的数据采集系统设计

在某型测试设备信号采集过程中,信号种类和采集通道多,数据量大。为此,本设计以凌华公司PXI总线控制机箱以及数据采集卡为硬件平台,以当前流行的虚拟仪器软件LabVIEW为运行平台,运用多线程,循环缓存与高速磁盘流等技术开发数据采集系统软件,实现了对信号的实时采集、存储与回放。实验结果表明,该软件运行稳定可靠,达到了预期的效果。

The Design of Signal Acquisition System with excessive styles and channels

In the course of the signal acquisition of certain test equipment,the sort of the signal and the acquisition channels are excessive and the amount of the data is also very large.Aiming at these features,this paper designs an signal acquisition system using the chassis and the data acquisition cards of Adlink as its hardware platform and LabVIEW as its software platform.To accomplish the real time acquisition,storage and playback of the signal,It uses the multithreading,circular buffer,the high speed disk cu...
