7 is a view of an embodiment showing an NFC antenna coil and a wireless charging antenna coil.

When the smart phone 30 or the portable terminal is placed on the charging table 20 of the present invention in a close contact state, it is possible to wirelessly charge the portable terminal, but short-range communication may also be possible. In this case, It is possible to further include an NFC 61b coil around the radio coil 61 connected to the radio output part 20 of the base station 20.

The charging table 20 transmits advertisement data to the smartphone 30 through the NFC 61b coil.

The coil may be a coil formed by printing an antenna loop coil on a PCB substrate (or a resin substrate) instead of a spiral coil by reducing the inductance value of the coil.

By forming a coil on the substrate, it is advantageous in mass production and can reduce the cost.

On the other hand, the number of turns is a number referred to as a standard to be applied to a mobile phone device. In general, a mobile phone device is a number generally calculated when the area is within a maximum of 100 cm square.

Although the substrate is not shown in the drawings, it is a matter of course that a multi-coil is provided on a flexible resin substrate or a general substrate (for example, a plastic substrate, a plastic substrate, or a metal substrate).

8 is a configuration diagram of the charging system in the wireless charging table.

The microcomputer 60 has various functions as shown in the figure and can receive data from the data receiver 60-1 according to various functions of the microcomputer and can receive data through the transmission status indicator 60-2 And can also output sound through the speaker 60-3. And through the current sensing unit 62c. And controls the operation of the frequency oscillator 62.

The new method is a technique capable of transmitting a higher power with a smaller area by raising the power transmission frequency, and the embodiment is carried out at a frequency of 7.2 Mhz.

Here, the most significant difference from the conventional method is that the power transmission frequency can be increased and higher power can be transmitted even in a small area. The frequency of the embodiment is 7.2 MHz.

The primary side coil part is configured to be able to transfer power to 7.2 Mhz, and it is different from the conventional technology to generate high frequency from the microcomputer and to transfer the power to the primary coil at a frequency of several Mhz units placed in the frequency oscillator have. A multiplexing coil is constructed and charged using a large area for free charging.

To summarize this, the following procedure is used.

Step 1: Portable device

In a first step, the portable receiver is placed on a charging plate consisting of multiple coils of a fixture transmitter.

Step 2: Power is supplied to the secondary coil of the portable device.

In the second step, the portable device is brought close to the primary coil in the fixing device. At this time, electric power is induced from the primary side and power is transferred to the secondary side, so that the portable device is powered and the microcomputer is revived.

Step 3: Portable device

Portable device The microcomputer is powered by the power supplied from the fixing device, and the charging circuit is activated to charge the battery.

Step 4: Fixing device current sensing part

The fixture detects that current is flowing from the current sensing circuitry to the portable device. That is, the fixing device knows that the portable device is mounted.

Step 5: Portable secondary coil

The portable device generates a pulse signal to apply a pulse signal to the secondary side indicating that it is being charged and shake the secondary side voltage.

Step 6: Fixing device primary coil

The voltage fluctuation of the secondary side pulse signal of the portable device is induced to the primary side, and the primary side voltage fluctuates according to the pulse signal at about 1V - 4V.

Step 7: Fixed Device Data Receiver

The fixed device data receiving unit receives the data transmitted from the portable device

Step 8: Fixed device microcomputer

And the data received from the fixing device microcomputer is processed. Then, it is recognized that the power receiver in the portable device is being charged.

However, if a metallic foreign substance is placed on the multiplexer coil of the radio transmission section, the following procedure is performed.

Step 1: Metallic foreign matter

In a first step, the metallic foreign object is placed on a charging plate composed of multiple coils of the fixing unit transmitter.

Step 2: The metallic secondary material is supplied to the secondary coil.

The metallic foreign substance is brought close to the primary coil in the fixing device. At this time, the electric power is induced in the primary side, and the electric current is induced by the metallic foreign substance.

Step 3: Fixed device current sensing unit

The fixture detects that current is flowing from the current sensing circuitry to the portable device. That is, the fixing device knows that the portable device is mounted. Although the electric current has flowed into the metallic foreign substance, it can not be known whether it is a portable device in the fixing device.

As a result of the test, the current of 30 mA for the coin case, 90 mA for the metal bar case, and about 180 mA when the metal plate was covered as much as possible, and a small current flow was experimentally confirmed.

Generally, the charging current is 700 mA, but it can be determined that the portable device is not charging due to the metal rod resistance. However, in the present invention, it is determined whether or not the portable device is based on data at the receiving portion of the portable device .

Step 4: Metallic foreign matter, no pulse signal is generated.

Step 5: Fixing device Primary coil,

There is no pulse signal with voltage fluctuation in the primary coil, which is a fixed device multiple coil.

Step 6: Fixed Device Data Receiver

Data can not be received from the fixed device data receiving unit.

Step 8: Fixed device microcomputer

Since there is no data received from the fixing device microcomputer, it is treated with a metallic foreign substance.

Step 9: Fixing device Microcomputer

The current is sensed to generate a charging current, but if the data is not received, it is determined as a metallic foreign matter, and the power is stopped without applying the power transmission frequency to the frequency oscillator corresponding to the current sensing coil group K.

Step 10: Fixing device Microcomputer, Speaker, Indicator LED

Foreign substance charge warning sound, indicator LED warning LED flashes.

Step 11: Fixed device multiple coil operation

The multiple coils extended to K without application of the frequency to the frequency oscillator corresponding to the current sensing negative coil group can apply the frequency to the continuous frequency oscillator and charge the extended other region. That is, the frequency is not applied to the power transmission frequency oscillator so that voltage is not applied to the primary coil so that only the position corresponding to the coil group where the charge current is leaked by the metallic foreign matter is leaked.

And the other extended coil group is configured to transmit electric power to the primary coil. So that it is charged.

The present invention relates to a configuration of a current sensing unit, which is related to a mounting position. When the current sensing part is directly connected in series to the coil end, the position is configured as follows in order to solve the impedance problems in each coil. The other end of the primary coil is connected to the opposite end of the coil group, and the ground GND1 is connected to the fixed power supply input terminal GND2, and the current sensing circuit is located between GND1 and GND2.

9 is a diagram showing a plurality of primary coils of the wireless charger transmitter.

(K1, K2, K3,,, Kn) may be present as a set of a plurality of coils (C1, C2, C3,,, Cn).

At this time, the specification used for manufacturing the wireless charger made of the coil is 6.78 MHz for the transmission frequency and 19V (300 mA) for the power. Of course, you can vary the frequency and frequency of the coil winding. For example, 6.5 Mhz may be used, and the outer coil may have a size of 38 mm x 42 mm and the inner coil arranged at the center may be 19 mm x 24 mm.

On the other hand, Kwon played two rounds on the outer rectangular quadrant with four turns and two turns on the middle small quadrant. As a result, the inductance of the coil has a value of 1 uH or less. At this time, it is natural that the player can do more than that.

Therefore, as a result, an insulating layer is provided between the first coil and the second coil and between the N-1 coil and the Nth coil, but a substrate may be provided. On the other hand, the insulating layer 33 is typically made of Sio2 (silicon oxide), resin, or the like. However, in the present invention, what is meant by the insulating layer is that the coating layer has characteristics that prevent electricity from flowing. The present invention is not an invention for an insulating layer, but a conventional insulating layer is applied to the present invention.

Of course, all N coils can be formed only on one side of the PCB (for example, front side or back side) of the PCB, and can be formed on the front side and the back side of the PCB.

More importantly, the outer coil and the inner coil form a pair, and the outer coil and the inner coil, which form the same pair, are formed on the same layer.

Of course, the inner coil formed in the outer coil need not necessarily be one, and two or more arbitrary N coils may be formed. In this case, one outer coil and N inner coils are paired together , One pair of coils are formed in the same layer.

10 shows a plurality of primary coil arrangement diagrams of a wireless charger transmission unit.

The purpose of the multiple superposition design of the primary coils is to enable wireless power transmission over a longer distance, and to provide a uniform field distribution over a large area so that wireless charging can be performed on any position of the charging plate.

As a result of constructing multiple primary side coils in multiple layers for longer distance transmission, it can be seen that sufficient charging power is transmitted even at intervals of 10 mm or more.

The purpose of superimposing the primary coils in multiple layers is to increase the strength of the magnetic flux by overlapping the magnetic fluxes generated by the mutual coils. As a result, the magnetic flux intensity is increased, Lt; / RTI >

In addition, as a result of superimposing a plurality of coils and coinciding magnetic fluxes generated between coils without increasing mutual attenuation, it is possible to construct a wide area power transmission device as well as wireless power transmission farther than the result, can do.

The principle that can perform this operation is the primary side coil structure diagram and the magnetic flux distribution. As a result of arranging a plurality of primary coils in a superimposed manner and constructing a coil structure with the same phase, the magnetic fluxes between adjacent coils are oriented in the same direction There was no attenuation, but rather the magnitude of the magnetic flux doubled.

As a result, the intensity of the magnetic flux was doubled by adding it to the magnetic flux of the adjacent coils, and the power transmission was possible to a far distance.

Test results are as follows

 _

 In the conventional method, when the distance is reduced by 1 mm, the wireless power can not be transmitted and wireless charging can not be performed. As a result, according to the present invention, 3.5 W, which is generally used in portable devices up to 10 mm, .

In the embodiment, the primary coil can be formed by using pcb or FPCB. In this embodiment, coils are formed by copper wire coated with enamel on the pc sheet and mounted.

FIG. 11 is a view showing an embodiment in which data is stored for each group and each portable terminal charger 100. In the database of the server 150 of the present invention, the time at which an advertisement is displayed for each charger 100 is stored.

For example, "00 area " refers to areas such as " Gangnam-gu ", and businesses existing in the Gangnam area are classified into " first group ", " second group "

In other words, if a plurality of portable chargers 100 are present in each branch, the number of each charger is divided into a number and an identification of each device, such as "Gangnam area" and "2nd group coffee shop" The code is distinguished.

Then, the charger 100 for all portable terminals is given an identification code, such as "No. 3 (identification code" lOOOO ") portable charger" of the "Gangnam area" and " The time at which the advertisement is displayed for each charger 100 is stored in the database of the server 150. [ At this time, the accumulated value may be given every time the advertisement is displayed, so that the accumulated value may be stored together with the type of the displayed advertisement.

FIG. 12 shows an embodiment in which advertisement information stored for each region is distinguished. In other words, restaurant is the most preferred advertisement in "00 area", and movie is the least preferred advertisement. The "0X area" is the most preferred advertisement for eating out, and the health care is the least preferred advertisement.

That is, in the server 150 of the present invention, the server 150 distinguishes a group or the like according to a restaurant or an area where the charger 100 for the portable terminal is located. In order to differentiate the types of advertisements transmitted from the server by each group, And related advertising preference information can be stored. Therefore, it is also possible to distinguish advertisement information transmitted from the server by region.

13 is a flowchart illustrating a method by which the server 150 transmits an advertisement. The server 150 receives the charging information transmitted from the portable terminal 100. This transfer process is performed through the steps of the embodiment of FIGS. 5 and 6. Then, the server stores charge start information for the portable charger that started charging (S160 - S165).

When the server 150 receives information indicating that fast charging is selected from the portable terminal 100, the controller of the server searches for the advertisement through the database and transmits the advertisement according to the method of the previous embodiment of the present invention. (S170 - S175)

Although the method of transmitting the advertisement is not described in the present invention, the advertisement method uses an ordinary method of sequentially transmitting the advertisement data in order.

The advertisement transmission time, the fast charging time, the charging time, etc. are stored for the unique identification number of the charger 100 for the portable terminal, respectively (S180 - S195)

When the charging is completed, the charging system for the portable terminal charger 100 is terminated (S200 - S205)

- Advertisement display algorithm -

A sensor 12 is further provided in the wireless output part 20 and the sensor 12 measures a voltage or a current value in the coil 61. [ The controller 10 senses the change of the current value or the voltage value through the sensor.

When the sensor is detected, the controller 10 transmits the advertisement data to the smartphone 30 through the NFC antenna coil. Then, the display of the smartphone displays advertisement data transmitted by the controller 10 .

Accordingly, when an advertisement is displayed on the display of the smartphone using the advertisement data received from the charging table, the time and advertisement information of the advertisement are stored in the database of the server.

FIGS. 14 and 15 are diagrams illustrating embodiments of a method of controlling an NFC antenna coil for transmitting advertisements and a wireless antenna coil for transmitting wireless power energy, respectively.

The process of supplying the power energy received from the coil 52 to the portable terminal 60 is similar to that of the previous embodiment. However, the data received through the NFC coil 51 is transmitted to the portable terminal 60 through a separate path.

As shown in the drawing, the receiving coil 52 and the NFC coil 51 are provided, and the two coils are separated in a circuit. Therefore, the control unit 110a for controlling the wireless power receiving unit and the NFC module 110b for controlling the NFC coil 51 are separately provided. In this case, the separate function means that the functions are separated, and thus the control unit 110a and the NFC module 110b may be separate components or functions may be distinguished from one component.

Therefore, the precise meaning of the two paths is that the connection line from the coil 51 to the control unit 110a and the connection line from the NFC coil 51 to the NFC module 110b are separated from each other.

The NFC module 110b is an NFC transmission module. The NFC transmission module includes an analog interface, an R / F level interface, a card mode detector, and the like. And the like.

In general, NFC is a non-contact type short-range wireless communication module that uses 13.56Mz frequency band as one of RFID tags and transmits data between terminals at a distance of 10cm. In addition to billing, NFC is used extensively in supermarkets and general stores for transporting travel information for goods information and visitors, as well as traffic and access control locks.

The switch 18 is further provided with a switch for blocking the connection under the control of the control unit 110a for controlling the coil. When the connection is blocked by the switch 18, the function of the NFC coil 51 Is stopped.

As a result, when the controller 110a controls the wireless power receiving coil to receive the wireless power receiving energy, the controller 110a turns off the switch to stop the NFC function.

On the other hand, when the wireless power reception energy is received, a method of stopping the NFC function may be other than the method disclosed in the present invention. Most importantly, when the control unit 110a controls the reception coil 51, it performs a control command to stop the NFC function.

14 is a diagram of another embodiment of the present invention. In this figure, the wireless power receiving coil 51 and the NFC coil 52 are provided in the main chip 110 (main chip: chip controlling the mobile terminal) .

15 also shows a control unit 110a and a NFC module 110b for controlling the wireless charging coil and a cellular phone control unit 110 so that the cellular phone control unit 110 also controls the control unit 110a and the NFC module 110b And when the coils suitable for the method are selected, the control unit 110a cuts off or connects the switch 18.
