基于Windows数据连续采集实时分析的实现及应用

A Continuous Acquisition and Real-time Analysis Method Based on Windows System

讨论在Window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 ,提高系统的工作效率 ,实现数据的连续采集和实时分析。采用该系统 ,可以在连续采集信号的同时进行信号分析 ,并且由于采用软件进行信号分析 。

The principlea and method of establishing 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 in the test process.With multi thread technology,the signal characteristics can be obtained the while sampling.The method is especially helpful to those tests which can not be repeated on the transient state vibration.Because signal analysis is implemented by software,the system can be easily expanded and configured.
