摘要
讨论了在Windows平台下建立信号连续采集实时分析系统的原理和方法 ,采用虚拟设备驱动程序 ,将数据采集卡数据存储到计算机内存缓冲区 ,信号分析处理模块从内存缓冲区中读取数据 ,同时采用多线程技术 ,提高了系统的工作效率 ,实现了数据的连续采集和实时分析。文中还对系统的一些关键问题和系统性能作了分析 ,并进行了实际应用。
A practical continuous acquisition and real-time signal analysis method based on Windows system is introduced. With VXD and memory block in computer,the system can also obtain all signal data during the test process,and analysis in lab.With multi-thread,the signal characteristics can be obtained the while sampling.The method is especially helpful to those tests which can not be repeated or the transient state vibration.
