摘要
介绍了一种用DIAMOND-MM-16-AT采集卡构建的基于PC 104总线的高速数据采集系统采集交流信号的方法,详细说明了采集卡的设置及初始化方法、变量定义及利用多线程、双缓冲区技术实现数据的高速采集和存储的方法,最后给出了滤波和计算交流有效值的算法。
The sampling method of AC signal in a high-speed sampling system based on the PC/104 bus composed by the sampling card DIAMOND-MM-16-AT is introduced. The methods of the sampling card setup, variables definition and high-speed data sampling and storage by multithreading and double buffers technology are explained in detail, and algorithms of the filter and the calculating method of AC rms are given in the end.
