  • It has a lot of strong interference signals in signals explored by transient electromagnetic method. If the strong interference signals ca'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 and function algorithm of LabVIEW platform to eliminate strong interference signal of the digital signal, so as to realize effective collection of transient electromagnetic data. The simulation result showed that the system can eliminate strong interference signal in transient electromagnetic data and ensures accuracy of collected data.
