POLARITY OF THUNDERCLOUD AND GROUND LEVEL ELECTRIC FIELD OBSERVATION DEVICE

摘要

An object of the present invention is to provide an apparatus for observing the polarity of a thundercloud and an apparatus for measuring an earth's magnetic field, which is capable of measuring the amount of electric charge generated when an electric field generated by thunderclouds is incident on an observing device and measuring the polarity of the thunderstorm and the magnitude of the earth electric field. To this end, the present invention provides a vacuum cleaner comprising: a housing having a hollow therein; A plurality of sensor units installed in the housing to detect an incident electric field; A shielding unit installed in the housing and periodically blocking an electric field incident on the sensor unit; A motor unit installed in the housing and rotating the shielding unit at a constant speed; A photo interrupt for detecting a position of the shield; A signal processing unit for calculating a charge amount value induced in the sensor unit from an electric field incident on the sensor unit, removing the noise from the calculated charge amount value, and outputting the removed noise signal as a digital signal; And a control unit for controlling the operation of the motor unit and analyzing the position signal of the shielding unit detected by the photointerruption and the waveform signal of the sensor unit output through the signal processing unit to determine the polarity of the thundercloud. Therefore, the present invention is advantageous in that the polarity of the thundercloud and the size of the ground electric field can be calculated more accurately by measuring the amount of electric charge induced when the electric field generated by thunderclouds is incident on the observation device.
