Abstract

The invention discloses a three-dimensional alternating electric field sensor calibrating device. The calibrating device includes a voltage regulator circuit unit, a sensor position control unit, a sensor output detection unit, and a calculation unit, the voltage regulator circuit unit is used for generating an alternating electric field between the upper electrode and the lower electrode of an electrode structure unit and for outputting the generated alternating voltage to the calculation unit, the sensor position control unit is used for controlling the position of a sensor according to the preset position, the sensor output detection unit is used for receiving the electric field output value detected by the sensor and sending the electric field output value to the calculation unit, the calculation unit is connected with the voltage regulator circuit unit and the sensor output detection unit and is used for simulating a three-dimensional alternating electric field, for calculating the different preset positions under different electrode structures and the corresponding actual electric field values under different voltages according to the simulated three-dimensional alternating electric field, and for calculating the calibration coefficient based on the linear relationship between the actual electric field value and the electric field output value. The calibration coefficients can be calculated automatically based on the sensor output value and the actual value of the electric field intensity under the different electrode structures, sensor positions and voltage conditions.

Description

Technical field [0001] The present invention relates to the field of electric field measurement, and more specifically, to a calibration device and method for a three-dimensional AC electric field sensor. Background technique [0002] At present, most of the electric field sensor calibration devices have a parallel electrode plate structure, which can only generate a uniform electric field between the electrodes, and the electric field type is single, which is only suitable for calibrating electric field sensors for measuring uniform electric fields. Moreover, there is currently no calibration device for calibrating electric field probes with non-uniform electric fields and distorted electric fields, and no device for calibrating spatial three-dimensional electric field sensor probes. In addition, the position of the electric field sensor cannot be adjusted flexibly, and the sensor calibration coefficient needs to be calculated manually. These factors make it impossible to calib...
