在工业及航空航天测控领域,实时数据采集存储是一个基本而且重要的环节.如何提高数据采集存储的实时性一直是技术人员所关心的问题.结合32位高速数据采集板7300A在星载干涉成像光谱仪高速数据采集记录系统的应用,阐述了在WindowsNT下用vc6.0实现高速数据采集、存储与实时显示过程.在实现过程中采用了多线程、定时器、双缓存和同步对象等技术,有效保证了光谱数据采集、存储与显示的稳定性、实时性,用高速数字采集卡实现了高速数字图像采集卡的功能.

Real-time data acquisition is a basic and important link on industry and aviation measure and control realm.How to increase the real-time quality of data collection and saving is a problem concerned by technical personnel.A high speed data acquisition system which has been used recording the secondary planet interferespectrometer imaging based on 32 bit high speed data collection card ADLINK PCI 7300A is described. The realization of high-speed data collection, saving and real-time displaying based on vc6.0 and Windows NT is elaborated.In the process the multithreading,timer,doublebuffer and synchronous object etc have been used, the system stability and real-time quality are effectively assured, the function of high speed digital image card is realized by digital I/O card.
