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。
In the field of industrial and aerospace monitoring and control, real-time data acquisition and storage is a basic and important part. How to improve the real-time data acquisition and storage has always been a concern of technical staff. Combined with the application of 32-bit high-speed data acquisition board 7300A in high-speed data acquisition and recording system of spaceborne interferometric imaging spectrometer, the high-speed data acquisition, storage and real-time display process using vc6.0 in Windows NT are described. Multi-threading, timers, double buffering and synchronization objects are used in the implementation process to effectively ensure the stability and real-time performance of spectral data acquisition, storage and display. High-speed digital capture card is used to realize high-speed digital image capture card Features.
