The Development Of The Lightning Radiation Field Data Acquisition System

In this paper, based on lightning monitoring system widely used in China's electric power system,use high-speed data acquisition card,Counter/Timer and Lumped controller, and take advantage of the data acquisition and control software weaved based on the virtual instrument, realized the electromagnetic field data collection, time Calibration and record. The hardware is mainly composed of GPS receiver, PXI6608 Counter/Timer and PX5105 Data Acquisition Card made by America NI Company, as well as the lightning detection stations. Virtual instrument is controlled using the software programmed by LabVIEW Through the PCI-e interface realized the control of the hardware system, realized the display, storage and time calibration of data collection, and even confirmed the system's reliability and accuracy by simulating lightning signal's long-term experiment.
