Description

[0002] Casino chips reading apparatus in casino tables [0003]

The present invention relates to a casino chip reading apparatus in a casino table, and more particularly to a system and method for minimizing mutual interference between antennas reading a plurality of casino chips placed on a casino table of an RFID (Radio Frequency Identification) To a casino chip reading apparatus in a casino table of an RFID system in which a betting area reading time is shortened by reading only a betting area in which a casino chip exists according to presence or absence of a casino chip.

RFID (Radio Frequency Identification) technology is a technology for attaching tags to objects and exchanging information between objects using data obtained by recognizing the tags wirelessly. We use various frequencies from 125kHz to 5.8Ghz.

Recently, RFID technology has been widely used in a one-to-one communication environment in which a large number of tags are concentrated, for example, a product on a shelf, a book on a bookcase, and a large number of tags on a casino table. In this case, recognition performance of tag is significantly lower than recognition of single tag due to interference between reader, tag, tag and tag. Therefore, it is necessary to develop a reader and an antenna considering the mutual electrical characteristics of the reader and the tag.

Among them, a casino table using an RFID method reads a tag using a plurality of antennas in a tray area and a bet area.

For example, FIG. 1 shows an antenna arrangement state in a tray area of a casino table. FIG. 1 shows a first antenna 10 having a matching circuit 11 and a conductor 12 for power supply, a matching circuit 21, A second antenna 20 with conductors 22 is proximate and laminated. This leads to a problem that accurate antenna matching becomes difficult due to mutual interference between antennas.

FIG. 2 is a state diagram of an antenna arrangement in the betting area of the casino table. FIG. 2 is a view showing the state of the antennas 61 to 63 of the readers reading the casino chips 31 to 33, 41 to 43, 51 to 53, do. In this case, the distance between the first antenna 61 and the second antenna 62 is shortened, and the second antenna 62 also operates with a magnetic field induced in the operation of the first antenna 61. Therefore, in the betting area of the casino, only the casino chips 31 to 33 stacked on the first antenna 61 need to operate during the operation of the first antenna 61. In the operation of the second antenna 62, The casino chips 41 to 43 stacked thereon also operate, which makes it impossible to apply them to actual business.

The method of reading the casino chip tag information of the betting area in the RFID system casino table shown in FIG. 2 is a method of reading the casino chip tag information of the betting area by using the first antenna (61 to 63, actually more antennas are present) For example, 61) to the last antenna (for example, 63), and reads the casino chip tag information of each betting area.

On the other hand, a conventional technique for reading a tag from an RFID casino table is disclosed in Patent Documents 1 to 3 below.

The prior art disclosed in Patent Document 1 is a smart casino table including a control unit for recording a batting liquid read by an RFID and a central checking unit in which a central antenna for RFID is mounted inside, By calculating the ratio between the amounts read, the casino business will be able to prevent overpayment and implement account management for the entire casino business in real time.

The conventional technology disclosed in Patent Document 2 enables the game chip to detect identification information of a game chip by using a game chip having an RFID tag embedded therein for each game table, By allowing the dealer to set the information management terminal device so as to monitor and manage the distribution of the game chip according to the progress of the game. Thus, the apparatus and the rolling chip for preventing the casino game table cheating are distributed according to the rules of the game Provides an effective casino table game chip management system for chip distribution management.

Through this, a casino table game chip management is realized in a rolling game operated in a casino using a casino chip having an embedded RFID tag.

In addition, in the conventional technology disclosed in Patent Document 3, a casino device, a casino table, and a casino game room are provided in such a manner that a dealer can purchase all chips that are exchanged between a dealer and a customer at the time of cache and chips handling such as chip purchase, chip refund, It stores contents in real time and can be checked in real time to dealers, customers and managers.

Hereinafter, an antenna for reading a casino chip in a casino table according to a preferred embodiment of the present invention and a casino chip reading device will be described in detail with reference to the accompanying drawings.

3 is a schematic block diagram of a casino table to which the present invention is applied.

The casino table 100 to which the present invention is applied is provided with a tray area 110 located on the dealer D side and a betting area 120 located on the player side P side.

The dealer D places the casino chip to be collected from the player or to be provided to the player in the tray area 110 and the player P places the casino chip to be bet on the betting area 120 at the time of betting.

FIG. 4 is a structural view of an antenna for reading a casino chip in a casino table 100 according to the present invention. A tray area 110 is provided below the plurality of antennas 130, 140, respectively.

An antenna for reading a plurality of casino chips is provided in the tray area 110. An antenna for reading a plurality of casino chips provided in this manner is formed in a close-up and laminated form.

Therefore, due to the proximity and stacking of the plurality of antennas, mutual interference occurs between the antennas, which makes it difficult to accurately match the antenna, making it difficult to accurately read the casino chips seated in the divided areas in the tray area.

4, the matching circuits 131 and 141 provided at the lower portion of the tray region 110 and the conductors 132 and 142 for feeding are basically identical to the basic circuit shown in FIG. Short circuits 133 and 143 are provided in a part of the conductors 131 and 142 of the antennas 130 and 140, respectively.

Although two antennas 130 and 140 have been described in the present invention, the present invention is not limited thereto. A large number of antennas are installed in the actual tray area 110, and the configuration and operation of each antenna have the same configuration and operation as those of the two antennas. Therefore, for simplification of the drawing and clarification of the description, only two antennas are shown as an example.

Here, the short circuits 133 and 143 internally include a short-circuit switch S / W for connecting and disconnecting both ends.

And an antenna controller 190 for controlling the short circuits 133 and 143 are additionally provided.

When reading the casino chip tag information of the tray area 110 using the antenna, the antenna controller 190 controls the short-circuit switch S / W in the short circuits 133 and 143 according to a predetermined order .

For example, when the tag information of the casino chip of a specific tray area is read using the first antenna (for example, 130), the shorting switch in the short circuit 133 of the first antenna 130 is turned on , The shorting switch in the short circuit 143 of the second antenna (for example, 140) is turned off. Then, the antenna loop is formed in the first antenna 130, but the antenna loop is turned off in the second antenna 140, so that the characteristic of the antenna is removed. That is, it can not function as an antenna. Thus, by controlling the mutual interference between the two antennas, the tag information of the casino chip located in the area of the first antenna can be accurately read without affecting the peripheral antenna. Similarly, when the tag information of the casino chip of the tray area is read using the second antenna 140, the shorting switch of the shorting circuit 133 is turned off and the shorting switch of the shorting circuit 143 is turned on (on). Thus, only the second antenna 140 is operated as an antenna, and the first antenna 130 removes the antenna characteristic, so that the tag information of the casino chip of the corresponding tray area can be accurately detected without interference of the peripheral antenna by the second antenna 140 Is accurately read.

Herein, each of the antennas 130 and 140 serves to read the casino chip tag information of the divided tray area obtained by dividing the entire tray area 110 again.

5 is a configuration of a casino chip reading antenna for reading tag information of a casino chip placed on the betting area 120 in the casino table 100 according to the present invention.

A plurality of antennas 161, 162, and 163 are installed below the respective betting areas of the casino table 100 to read RFID tag information of the casino chip placed on the betting area. Although only three antennas are illustrated in the present invention, the present invention is not limited thereto, and the same applies to a smaller or larger number of antennas.

An antenna (for example, 151) provided at the bottom of each batting area includes a matching circuit and a conductor for feeding.

There are a large number of betting areas in the actual casino table. The number may vary depending on the size of the casino table. When the player puts the casino chip in the betting area at the time of game, the tag information of the casino chips (for example, 31 to 33) loaded on the betting area is read by the antenna 151 provided at the lower end of the betting area. At this time, the antenna 152 provided at the lower end of the other betting area close to the betting area also reads the tag information of the casino chips (for example, 41 to 43) placed on the betting area.

At this time, a magnetic field is generated between the first antenna (for example, 151) and the second antenna (for example, 152) The magnetic field generated by the antenna is induced to the adjacent antenna. As a result, if an antenna without an actual casino chip is operated, a casino chip may malfunction due to a magnetic field generated from another antenna.

In order to solve such a problem, the present invention is characterized in that magnetic field shielding members 161, 162 and 163 for shielding a magnetic field are formed around conductors provided in the respective antennas 151, 152 and 153, .

Here, the magnetic field shielding members 161, 162, and 163 are preferably provided in the same shape as the shape of the conductor so as to surround the outer circumferential surface of the conductor provided in each antenna.

The magnetic field barrier material may use any one of metal, ferrite, and soft magnetic material capable of blocking the magnetic field. In addition to what is mentioned here, all known magnetic field shielding materials capable of magnetic field shielding can be used.

The magnetic field barrier material and the conductor are formed in such a way that the antenna can be inserted into the magnetic field shielding material so that the magnetic field generated by the antenna inside the magnetic field shielding material flows out to the outside of the antenna.

6 is a configuration diagram of a casino chip reading apparatus in a casino table for reading out a plurality of antennas formed as shown in FIG.

A plurality of antennas 161, 162, and 163 for reading tag information of the casino chips 31 to 33, 41 to 43, 51 to 53 placed in a plurality of betting areas; A casino chip sensing unit (171-173) for sensing whether a casino chip exists in the plurality of betting areas; And determines whether or not there is a casino chip in the betting area in cooperation with the casino chip detecting units 171 to 173 and determines whether or not there is a casino chip in the betting area through reading control of the plurality of antennas 161 to 163 based on the determined presence / And a read controller 180 that shortens the casino chip information reading time of the casino chip.

Here, the casino chip sensing units 171 to 173 are provided below the betting area 120 provided in the casino table 100, and use a weight sensing sensor for sensing the presence or absence of a casino chip through weight sensing, A light sensor for detecting the presence or absence of a casino chip can be used. It is also possible to use all known sensors capable of detecting the presence or absence of a casino chip in addition to the weight detection sensor and the light detection sensor.

The operation of the casino chip reading apparatus in the casino table according to the present invention will be described in detail as follows. At the time of the game, the player P places the casino chip he bet on the betting area. Here, the betting area is formed in various numbers depending on the size of the casino table and the like.

When the game is started, the casino chip sensing units 171 to 173 provided below the respective betting areas detect the presence or absence of the casino chips in the betting area. The method of detecting the presence or absence of a casino chip is performed by installing sensors such as light, weight, electric field, magnetic field, and the like on the basis of the change in load when the casino chip is loaded, It is possible to use a method of judging the presence of a chip, a method of detecting an electric field and a household, receiving light when the light is radiated and reflected by the casino chip, and determining that the casino chip exists. When light is used, the casino table can be applied to a glass table which is formed in a transparent glass form.

The determination result of the presence or absence of a casino chip detected by each of the casino chip sensing units 171 to 173 is transmitted to the read controller 180 in real time.

At the start of the game, the read controller 180 controls the casino chips using only the antenna located in the betting area detected as the existence of the casino chip, based on the determination result of the presence / absence of the casino chip that is generated in each of the casino chip sensing units 171 to 173 And the antenna located in the betting area detected as having no casino chip controls the antenna reading in such a way as to skip the reading of the casino chip information.

For example, the read controller 180 determines whether or not the casino chip is present based on the determination result of the presence / absence of a casino chip in the bet area detected by the casino chip detectors 171 to 173, And controls the betting area reading so as to skip the reading of the casino chip information for the betting area where the casino chip does not exist.

By controlling the reading of the antenna in this manner, the casino chip reading time for the entire betting area of the casino table can be shortened compared with the conventional method.

Especially, as the size of the casino table is large, the more the betting area is, the shorter the reading time of the casino chip becomes, and the power consumption for reading the casino chip can be reduced by shortening the reading time of the casino chip.

7 is a block diagram of another embodiment of a casino chip reading apparatus according to the present invention.

An antenna 181 for reading tag information of the casino chips 301 to 303 placed in a plurality of betting areas 191 and 192; A casino chip sensing unit (200) for sensing which of the plurality of betting areas a casino chip is present in; And a read controller 201 that interlocks with the casino chip detector 200 to identify a betting area where a casino chip is present and to read casino chip information through the antenna 181. [

In another embodiment of the casino chip reading apparatus, the casino chip detecting unit 200 is installed in only one of a plurality of betting areas.

Then, in a game, the player places a casino chip on a betting area among a plurality of betting areas 191 and 192 provided on one antenna 181 to bet.

Then, the casino chip sensing unit 200 reads the presence or absence of the casino chip by any one of light, weight, electric field, and magnetic field. At this time, the casino chip sensing unit 200 is installed in a specific area, The presence or absence of a casino chip in the betting area is detected. Assuming that the casino chip sensing unit 200 is installed below the betting area 191, the casino chip sensing unit 200 senses the casino chip sensing unit 200 only when the player places the casino chip on the betting area 191, To the controller (201).

The read controller 201 determines that the casino chip is loaded in the betting area 191 when the casino chip sensing signal is transmitted by the casino chip sensing unit 200 and the casino chip sensing unit 200 If the casino chip detection signal is not transmitted, it is determined that the casino chip is bet on the betting area 192.

The tag information of the casino chip placed on the betting area is read through the antenna 181 to determine the bet amount.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to a technology for improving the antenna performance of the tray area and the betting area in the RFID system, and for shortening the time for reading the casino chip using the antenna.
