| 摘 要： | 采用瞬变电磁法勘探到的信号中包含大量的强干扰信号,如不剔除强干扰信号,反演得到的计算结果误差较大。针对该问题,提出了一种基于LabVIEW的瞬变电磁数据采集及预处理系统的设计方案。该系统采用数据采集卡USB2089采集二次涡流场信号,并将其转换为计算机能处理的数字信号,然后通过LabVIEW平台的功能流程、功能算法剔除数字信号中的强干扰信号,从而实现对瞬变电磁数据的有效采集。仿真结果表明,该系统可剔除瞬变电磁数据中的强干扰信号,保证了数据采集的准确性。

| Abstract: | It has a lot of strong interference signals in signals explored by transient electromagnetic method.If the strong interference signals can't be eliminated,error of calculating result will be big.So the paper proposed a design scheme of collection and pretreatment system of transient electromagnetic data based on LabVIEW.The system uses data collection card USB2089 to collect secondary turbulence field signal and transfer the signal to digital signal that can be processed by computer,then uses function flow ... |
