Description
DESCRIPTION
RADIO POWER SUPPLY TERMINAL
FIELD OF THE INVENTION
The present invention relates to the way of supplying electricity by using electromagnetic wave.
BACKGROUND OF THE INVENTION
Radio power has been supplied as media doing remote communication like RFID. However, it's not fully supplied due to the influence on human body cased by frequency characteristic.
Power supply is necessary in case of using electric circuit. Therefore, as it stands, power is supplied by installing battery in media that places emphasis on functions. Also, there are a few radio communication media (that is not
RFID) that supplies electricity by connecting to power code.
Using power code violates the value of radio in radio communication media.
It is a problem whether to use radio power with limited function or give priority to function with the physical way of power supply.
Also, the power supply method incurs cost of manufacturing and maintenance. Therefore, it is not accepted in
RFID although there is infinite of possibility applied for logistic system.
SUMMARY OF THE INVENTION
The subject of the present invention is to supply electricity in long distance by using the band of ELF or VLF.
The present invention is to solve the above-mentioned subject.
The present invention is ideal for a) supplying power by inductive coupling in magnetic field using long wave like ELF or VLF. b) getting resonant frequency required for radio wave from like a crystal oscillator. c) getting resonant frequency required for radio wave by mixing required frequency in AC power source like AC outlet in advance.
The present invention makes possible to supply much electricity than the existing radio electric power supply. Moreover, it prevents for bad influence caused by resonating with human body like high frequency band. This is because it is physically impossible to resonate with human body due to wavelength in long wave band gets extremely long as several kilo-meter.
The invented radio power supply terminal is to supply power by inductive coupling using ELF or VLF band.
BRIEF DESCRIPTION OF THE DRAWING
Figure 1 is represents the embodiment 1 of radio power supply terminal.
Figure 2 represents the embodiment 2 of Radio power supply terminal.
DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the invention is represented by Figure 1.
AC power (4) is connected to AC outlet or distribution equipments. It is possible AC power (4) to be used as power for electric circuit by converting into DV internally. Oscillating frequency signal required for output resonant circuit (1) is extracted out of AC power (4) by resonating frequency extraction circuit (2). This is the same technology as power line communication in terms of mixing and extracting this oscillating frequency.
However, that is one of the peripheral technologies, and does not relate to the subject of the presented invention to be solved. The signal comes from resonating frequency extraction circuit (2) through transistor (3) is sent to output resonant circuit (1). Electromagnetic wave is generated by output resonant circuit (1). Power receive device equipped close to radio electric power terminal gets power by inductive coupling. The power receive device as mentioned above has the same power receive function with resonating frequency as Radio power supply terminal. WHIe Figure 1 shows the method to receive resonating frequency signal through AC power (4),
Figure 2 shows the method to regard as oscillating source of output electromagnetic wave by installing oscillating circuit like crystal oscillator (7).
In this way, it becomes possible to output electromagnetic wave for electric power supply without converting distribution equipments like power communication technology. hi relation to the invented radio electric supply terminal, frequency band is not limited in using electromagnetic wave. However, long wave band like ELF or VLF has an advantage for use considering distance and the influence on human body.
As a example, magnetic field intensity at the point of 1 meter and 10 meters with random frequency is calculated as below.
Magnetic field intensity=I-N"RΛ2/2V~(RΛ2+xΛ2)Λ3
I = Current, N = Coil's number of turns, R = Coil's radius, x = distance from the center of coil
I= IOA, N = IOO, R=IOm, x= lm
10 * 100 * (10 * 10A-3) / 2π((10 * 10Λ-3)Λ2 + 1Λ2)Λ3 = 5m
As a result above, 5mA/m of magnetic field intensity is secured at the point of 1 meter.
At the point of 10 meters, 5 uA/m is seemed due to 6OdB reduced by being inversely proportional to 10 times
of distance.
This invention makes possible to install Radio power supply terminal easily.
As shown as Figure 1, the structure of the invention is very simple and it is impossible to realize.
Therefore, it is easy to assume it is possible to downsize.
