It may include a program designed to stop and power up by

The PCB circuit board unit 330 detects a grounded line among the 110V or 220V/50Hz power lines supplied for home use, and if the grounded line is not detected, a virtual neutral grounding circuit inside the earthing controller 300 It is configured to provide an ideal grounding state by inducing the grounding antenna 360 to be grounded with the ground surface.

In addition, the PCB circuit board unit 330 can independently configure a bypass circuit so that the impedances are the same to AC1 and AC2 of the supply power, and also switch to the triacs (TH2, TH1) of the microcomputer 380. It can be configured to sequentially detect three states of VCC, that is, REL1 (332), REL2 (334), and REL3 (336) at regular time intervals.

Here, the microcomputer 380 is induced from the ground surface to the ground antenna 360 in the state of REL1 (332), REL2 (334), and REL3 (336) detected through the detection relay unit 350 by 50 to 60 Hz electric field. It is configured to convert the voltage into AC, and to store the voltages of the REL1 ( 332 ), REL2 ( 334 ), and REL3 ( 336 ) states as digital data signals, respectively.

For example, when VCC is connected to REL1(332) (TH2 ON) by selecting the lowest value among REL1(332), REL2(334), and REL3(336) states, if it is the lowest value, TH2 is ON and TH1 is OFF. is to keep In addition, if VCC is connected to REL2 (334) is the lowest value, TH2 is OFF and TH1 is ON. is formed so that

That is, the structure is formed so that the ground antenna 360 is grounded with the ground by finding the lowest value (lower value) among the states of REL1 ( 332 ), REL2 ( 334 ), and REL3 ( 336 ).

At this time, it is preferable that the microcomputer 380 is configured such that VCC and VSS alternately maintain a low impedance, and VCC and VSS are identical. This is to configure the grounding antenna 360 to ground the lowest value selected by the microcomputer 380 by the ground surface.

More specifically, when the surface of the electrostatic switch 390 is depressurized, the grounding antenna 360 generates a grounding potential signal to the grounding antenna 360 installed around the grounding potential circuit while passing a current for power operation.

After measuring and if the ground potential does not occur, REL2 (334) and REL3 (336) are driven in order to differentiate and fix the ground potential. When the finger is removed from the electrostatic switch 390, the potential identification program is stopped and configured to operate the power supply.

At this time, the power is not turned on if you release your finger while the electrostatic switch 390 is being pressed before the detection of the ground potential is completed. The process may be omitted and a program designed to be applied with power immediately may be included.

In the above program, the ground potential signal detection operation of the ground antenna 360 is performed only in the initial screening process when the first power is applied, and the ground potential signal detection operation is performed when the power cord 320 of the earthing controller 300 is always connected to the outlet. Skip it and allow the power to be applied immediately.

In addition, the ground antenna 360 may include a program designed so that the power is not operated while the electrostatic switch 390 is changed from the reduced pressure state to the non-decompressed state before the ground potential signal is detected.

That is, the power should not be turned on while the electrostatic switch 390 is being pressed, and the power should not be turned on if the hand is released before the detection of the ground potential is completed.

At this time, the above process should be repeated until the power is turned on again. And until the power is disconnected, the power can be turned on immediately, and the driving of the potential identification program in the above process is omitted.

In addition, when the power cord is unplugged and plugged in again, the above process is initialized and the potential identification program is restarted.

In particular, in the process of performing the above operation, the carbon grounding member 370 is capable of attenuating the electromagnetic wave generated by the earthing controller 300 due to the characteristic having conductivity, and organically works with the grounding antenna 360 and the microcomputer 380. Accordingly, most of the electromagnetic waves can be discharged to the ground so as not to affect the human body.
