Design of a Lightning and Ground Electric Field Monitoring Integration

A lightning and ground electric field monitoring integration is designed,which includes the ground electric field monitoring unit,lightning detection unit and signal and data processing unit.Ground electric field monitoring unit consists of MCU module,field instrument,amplifiers,filters and self-test/self-calibration module.Lightning detection unit inculdes the antenna assembly,three preamplifier circuits,three signal conditioning circuits,waveform discrimination circuit,photoelectric cell and lighting detection module.Signal and data processing unit is used for processing the received signal on the preceding,and transmitted to the computer for display via the communication interface.Because the lightning prediction and lightning location functions are integrated in one,the shortcomings of a single device such as not easy to carry and low detection accuracy,are overcome,so the precision and accuracy of the lightning monitoring are improved.
