针对市面上电场传感器只能探测一维电场垂直分量且电场测量结果存在一定的误差,为了更加精确地测量大气电场强度,提高雷暴云预警的准确率,提出一种场磨式三维大气电场传感器,传感器主要结构由屏蔽罩、感应电极、光电开关、叶片和电机组成,电路设计主要包括I-V转换电路、差分放大电路、峰值检测电路和滤波电路等,进行传感器实地电场测量实验并整理实验数据;实验结果表明,该传感器能够对环境电场进行水平和垂直分量测量,有效反映了环境电场特征,验证了场磨式三维大气电场传感器结构设计和电路设计的有效性。

In view of the fact that the electric field sensor in the market can only detect the vertical component of one-dimensional electric field,and there are some errors in the electric field measurement results,in order to measure the intensity of atmospheric electric field more accurately and improve the accuracy of thunderstorm cloud early warning,this paper proposes a field-grinding three-dimensional atmospheric electric field sensor.The main structure of the sensor is composed of a shield,an induction electrode,a photoelectric switch,a blade and a motor.The circuit design mainly includes an I-V conversion circuit,a differential amplifier circuit,a peak detection circuit and a filter circuit,etc.,and the field electric field measurement experiment of the sensor is carried out and the experimental data are sorted The experimental results show that the sensor can measure the horizontal and vertical components of the environmental electric field,which effectively reflects the characteristics of the environmental electric field,and verifies the effectiveness of the structural design and circuit design of the field grinding three-dimensional atmospheric electric field sensor.
