According to the principle of aero-transient electromagnetic method and its signal characteristics, according to the requirements of long-time continuous acquisition and storage, an airborne transient electromagnetic data acquisition system based on LabVIEW is designed. System hardware platform with NI PXIe-4492 Dynamic signal acquisition card as the core, with Ni pxie-6674t and NI pxi-6682h and other auxiliary board to build; the software part uses LabVIEW to write, using producer/consumer mode, combined with user event processing loop and queue Message processor, realizes the function of data continuous collection, storage, real-time processing and display, and resolves the issue that the transmit and receive clocks are out of sync. Finally, the experiment shows that the system can be collected stably for a long time, and the performance satisfies the design requirements.
