摘要:
针对研究院所研制的产品具有多传感器和数据传输速度快等特点,提出一种基于面向仪器系统的外设部件互连标准扩展总线平台的实时高速数据采集系统的设计方法,用于实现对产品性能的检测.该系统通过现场可编程门阵列将多通道传感器信号调理成为单通道低电压差分信号供图像采集卡进行采集,在上位机中采用LabVIEW的编程环境中构建的测试软件对采集得到的图像信号进行解析和存储,并将解析的结果按照一定的显示形式在虚拟仪器的面板上显示.测试软件可以通过对解析结果分析被测产品是否出现故障,并对故障信息进行记录和定位,操作员可以通过回放存储的数据对出现故障进行深入分析其原因.实验结果表明,在对100帧/秒、每帧图像为128×128×16位的实验环境中,在LabVIEW强大的自动多线程的编译环境下,只需要很低CPU的使用率和内存占用率就可以保证系统的图像采集、分析、存储和显示等多个线程准确有序的并行运行.测试系统有效地实现了高速图像信号的实时采集和分析,并且为传输速度更快的图像采集系统提供了一种可能性.
Abstract:
A kind of realtime highspeed image data acquisition system based on peripheral component interconnect standard extensions for instrumentation bus platform design method was presented to inspect the performances of the product. In this system, multichannel sensor signal was transformed into the singlechannel low voltage differential signaling by using the field programmable gate array multichannel, and then the transformed signal was collected by the image acquisition card. In the host computer, the collected image signal was resolved and stored by the test software which was established on the LabVIEW programming environment, and then the resolved signal was displayed on the panel of the virtual instrument in a certain of form. The fault was detected, recorded and located by the results of analysis through the test software, the reason leading to the fault point was deeply analyzed in the way of operator watching the playback of the stored data. The experimental results show that, in the environment of the transmission rate of 100 frame persecond, the image size of 128×128×16 pixels per frame, and the powerful capabilities of LabVIEW automatic multithreading, the test software can run on low CPU and memory usage, which ensures the parallel thread of image acquisition, analysis, store and display operating orderly and accurately; the highspeed image acquisition and analysis system is embodied, which provides a possibility for the higherspeed image acquisition.
