Title:
ELECTROMAGNETIC WAVE MEASURING APPARATUS FOR ELECTRIC DEVICE AND MEASURING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/023029
Kind Code:
A1
Abstract:
The present invention relates to an electromagnetic wave measuring apparatus for an electric device and a measuring method using the same, which accurately detect numerical values of the electric field and magnetic field of an electric device used in daily life and thus induce a preliminary perception of a user to prevent the user from being exposed to the danger of electromagnetic waves, and mixedly use different methods for the measurement, thereby having an accurate measurement despite the interference of external elements and a change in the measurement conditions. The present invention includes: a high-frequency oscillator for transferring, to a frequency counter and a first amplifier, an analog signal of electricity supplied from a power supply unit to which the power of the electric device is applied and oscillating a high frequency; and a first sensor unit that receives a signal from the high-frequency oscillator and includes a first to third electromagnetic induction sensors, which are installed in the X-axis, Y-axis, Z-axis directions from a center line of the electric device, to measure electromagnetic waves in the three directions using an electromagnetic induction method, respectively, wherein a measured modulation value and an electric signal amplified in the first amplifier are transferred to a computing unit, the measured modulation value being obtained by a magnetic field modulator by changing the electromagnetic wave values on the X-axis, Y-axis, and Z-axis measured by the first to third electromagnetic induction sensors of the first sensor unit, and are then calculated as the electric field (V) value and the magnetic field (G) value, thereby displaying a digital value, which has been converted from an analog electromagnetic value, in a display window. Therefore, the present invention enables the user to confirm the electromagnetic waves and ensures the user's safety.
