카지노 테이블에서 카지노 칩 판독 안테나 및 카지노 칩 판독장치Casino chip readout antenna and casino chip reader at casino table
본 발명은 카지노 테이블(casino table)에서 카지노 칩 판독 안테나 및 카지노 칩 판독장치에 관한 것으로, 특히 RFID(Radio Frequency Identification) 방식의 카지노 테이블에 안착된 복수의 카지노 칩을 읽어들이는 안테나 간의 상호 간섭을 최소화하고, 배팅 영역의 카지노 칩 존재 유무에 따라 카지노 칩이 존재하는 배팅 영역만을 판독함으로써 배팅 영역 판독시간을 단축하도록 한 RFID 방식의 카지노 테이블에서 카지노 칩 판독 안테나 및 카지노 칩 판독장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a casino chip reading antenna and a casino chip reading device in a casino table. In particular, the present invention relates to mutual interference between antennas for reading a plurality of casino chips mounted on a radio frequency identification (RFID) casino table. The present invention relates to a casino chip reading antenna and a casino chip reading apparatus in an RFID-type casino table which minimizes and shortens the betting area reading time by reading only the betting area in which a casino chip exists according to the presence or absence of casino chips in the betting area.
RFID(Radio Frequency Identification) 기술은 사물에 각각의 태그(Tag)를 부착하고, 이를 무선으로 인식하여 획득한 데이터를 이용하여 사물 간의 정보 등을 교환하는 기술이다. 사용하는 주파수는 125khz ~ 5.8Ghz까지 다양한 주파수를 사용하고 있다. RFID (Radio Frequency Identification) technology is a technology that attaches each tag to a thing, and exchanges information between things using data acquired by recognizing it wirelessly. The frequency used is from 125khz to 5.8Ghz.
최근의 RFID 기술은 일대일 통신방식에서 태그가 다량으로 밀집된 환경, 예를 들어, 선반에 진열된 제품, 책꽂이에 비치된 도서, 카지노 테이블 위에 있는 다량의 태그(Tag) 등 동시에 다량의 태그를 인식하는 방향으로 발전하고 있으며, 이 경우 리더와 태그, 태그와 태그 상호 간의 간섭으로 인하여 단일 태그를 인식하는 것보다 태그의 인식 성능이 크게 저하된다. 따라서 리더 및 태그의 상호 전기적 특성을 고려한 리더 및 안테나의 개발이 점차 필요하다.Recent RFID technology recognizes a large number of tags simultaneously in a one-to-one communication, such as an environment where a large number of tags are arranged, for example, products displayed on shelves, books on a shelf, and a large number of tags on a casino table. In this case, due to the interference between the reader and the tag, and the tag and the tag, the recognition performance of the tag is much lower than that of the single tag. Therefore, it is necessary to develop a reader and an antenna considering the mutual electrical characteristics of the reader and the tag.
그 중 RFID 방식을 이용하는 카지노 테이블에는 트레이 영역에서와 배팅 영역에서 다수의 안테나를 이용하여 태그를 판독한다.Among them, a RFID table reads a tag using a plurality of antennas in a tray area and a betting area.
예컨대, 도 1은 카지노 테이블의 트레이 영역에서의 안테나 배치 상태도로서, 매칭회로(11)와 급전을 위한 도체(12)를 구비한 제1안테나(10)와, 매칭회로(21)와 급전을 위한 도체(22)를 구비한 제2안테나(20)가 근접 및 적층된다. 이로 인해 안테나 간의 상호 간섭으로 정확한 안테나 매칭이 어려워지는 문제점을 유발하였다.For example, FIG. 1 is a diagram illustrating an antenna arrangement in a tray area of a casino table, the first antenna 10 having a matching circuit 11 and a conductor 12 for feeding, a matching circuit 21 and a feeding The second antenna 20 with the conductor 22 is adjacent and stacked. As a result, accurate antenna matching is difficult due to mutual interference between antennas.
도 2는 카지노 테이블의 배팅 영역에서의 안테나 배치 상태도로서, RFID 태그가 부착된 카지노 칩들(31 ~33, 41 ~ 43, 51 ~ 53)을 판독하는 복수의 리더기의 안테나(61 ~ 63)가 구비된다. 이 경우, 제1 안테나(61)와 제2안테나(62)의 거리가 근접되어, 제1안테나(61)의 동작시 유기되는 자장으로 제2안테나(62)도 동작한다. 이로 인해 카지노의 배팅 영역에서는 제1안테나(61)의 동작시에는 제1안테나(61)의 상부에 적층된 카지노 칩들(31 ~ 33)만 동작해야 하는 데, 제2안테나(62)의 동작으로 그 위에 적층된 카지노 칩들(41 ~ 43)도 동작하기 때문에, 실제 업무에 적용하기가 불가능한 단점이 있다.FIG. 2 is a diagram illustrating antenna arrangement in a betting area of a casino table, and includes antennas 61 to 63 of a plurality of readers that read casino chips 31 to 33, 41 to 43, 51 to 53 with RFID tags. do. In this case, the distance between the first antenna 61 and the second antenna 62 is close, and the second antenna 62 also operates as a magnetic field induced when the first antenna 61 is operated. Therefore, in the casino betting area, only the casino chips 31 to 33 stacked on the first antenna 61 should be operated when the first antenna 61 is operated. Since casino chips 41 to 43 stacked thereon also operate, there is a disadvantage that it is impossible to apply to actual work.
또한, 도 2와 같은 RFID 방식의 카지노 테이블에서 배팅 영역의 카지노 칩 태그 정보를 판독하는 방식은, 복수의 안테나(61 ~ 63, 실제로는 더 많은 안테나가 존재함)가 존재할 경우, 첫 번째 안테나(예를 들어, 61)부터 마지막 안테나(예를 들어, 63)까지 순차로 판독을 하여, 각각의 배팅 영역의 카지노 칩 태그 정보를 판독한다.In addition, the method of reading the casino chip tag information of the betting area in the RFID table of the RFID method as shown in FIG. 2 is based on the first antenna (if there are a plurality of antennas 61 to 63 (in fact, more antennas exist). For example, reading is sequentially performed from 61 to the last antenna (for example, 63) to read casino chip tag information of each betting area.

도 3은 본 발명이 적용되는 카지노 테이블의 개략 구성도이다.3 is a schematic configuration diagram of a casino table to which the present invention is applied.
본 발명이 적용되는 카지노 테이블(100)은 딜러(D) 쪽에 위치한 트레이 영역(110), 게임자(P) 쪽에 위치한 배팅 영역(120)이 구비된다.The casino table 100 to which the present invention is applied is provided with a tray area 110 located at the dealer D side and a betting area 120 located at the player P side.
딜러(D)는 게임자로부터 회수하거나 게임자에게 제공할 카지노 칩을 트레이 영역(110)에 놓게 되고, 게임자(P)는 배팅 시 배팅 영역(120)에 배팅할 카지노 칩을 올려놓게 된다.The dealer D puts casino chips to be collected from the player or provided to the player in the tray area 110, and the player P places the casino chips to bet on the betting area 120 when betting.
도 4는 본 발명에 따른 카지노 테이블(100)에서 카지노 칩 판독 안테나의 구조도로서, 트레이 영역(110)이 하부에 구비되어, 카지노 칩에 설치된 RFID 태그 정보를 판독하는 복수의 안테나(130, 140)를 도시한 것이다.4 is a structural diagram of the casino chip read antenna in the casino table 100 according to the present invention, the tray area 110 is provided at the bottom, a plurality of antennas (130, 140) for reading the RFID tag information installed in the casino chip It is shown.
트레이 영역(110)에는 다수의 카지노 칩 태그 판독 안테나가 마련되는 데, 이렇게 마련되는 다수의 카지노 칩 태그 판독 안테나는 근접 및 적층 형태로 구성된다.The tray area 110 is provided with a plurality of casino chip tag read antennas, which are provided in proximity and stacked form.
따라서 복수 안테나의 근접 및 적층에 의해, 안테나 간의 상호 간섭이 발생하고, 이로 인해 정확한 안테나 매칭이 어려워, 트레이 영역 내의 분할된 영역에 안착된 카지노 칩을 정확하게 판독하는 것이 어려워지게 된다.Thus, proximity and stacking of multiple antennas cause mutual interference between antennas, which makes it difficult to accurately match antennas, making it difficult to accurately read casino chips that are seated in divided regions in the tray area.
본 발명은 상기와 같은 문제점을 개선하기 위해서, 도 4에 도시한 바와 같이, 트레이 영역(110)의 하부에 설치되는 매칭 회로(131, 141)와 급전을 위한 도체(132)(142)로 기본적으로 구성되는 각각의 안테나(130, 140) 중 도체(131, 142)의 일부에 단락 회로(133, 143)를 설치한 것이다.In order to solve the above problems, the present invention basically includes matching circuits 131 and 141 installed below the tray area 110 and conductors 132 and 142 for feeding. The short circuits 133 and 143 are provided in a part of the conductors 131 and 142 among the antennas 130 and 140 constituted by the antennas.
본 발명에서는 2개의 안테나(130, 140)를 예시로 설명하였으나, 본 발명은 이것에 한정되는 것은 아니다. 실제 트레이 영역(110)에는 많은 수의 안테나가 설치되며, 각각의 안테나의 구성 및 동작은 상기 2개의 안테나와 동일한 구성과 동일한 작용을 한다. 따라서 도면의 간소화와 설명의 명료화를 위해 단지 2개의 안테나에 대해서만 예시로 표시한 것이다.In the present invention, two antennas 130 and 140 have been described as an example, but the present invention is not limited thereto. The actual tray area 110 is provided with a large number of antennas, the configuration and operation of each antenna has the same operation and the same configuration as the two antennas. Therefore, only two antennas are shown as examples for the sake of simplicity and clarity of description.
여기서 단락 회로(133, 143)는 내부적으로 양단을 연결 및 차단하기 위한 단락 스위치(S/W)를 포함한다.Here, the short circuits 133 and 143 include a short switch S / W for connecting and disconnecting both ends internally.
그리고 상기 단락 회로(133, 143) 제어를 위한 안테나 제어기(190)가 별도로 구비된다.In addition, an antenna controller 190 for controlling the short circuits 133 and 143 is provided separately.
안테나를 이용하여 트레이 영역(110)의 카지노 칩 태그 정보를 판독할 경우, 먼저, 정해진 순서에 따라 안테나 제어기(190)는 상기 단락 회로(133, 143) 내의 단락 스위치(S/W)를 제어한다. When reading the casino chip tag information of the tray area 110 using an antenna, first, the antenna controller 190 controls the short switch S / W in the short circuits 133 and 143 in a predetermined order. .
예컨대, 제1안테나(예를 들어, 130)를 이용하여 특정 트레이 영역의 카지노 칩의 태그 정보를 판독할 때, 제1안테나(130)의 단락 회로(133) 내의 단락 스위치는 온(on)하고, 제2안테나(예를 들어, 140)의 단락 회로(143) 내의 단락 스위치는 오프(off)시킨다. 그러면 제1안테나(130)는 안테나 루프(loop)가 형성되나, 제2안테나(140)는 안테나 루프가 오프가 되어, 안테나의 특성이 제거된다. 즉, 안테나로서 작용할 수 없게 된다. 이로써 2개의 안테나 간의 상호 간섭을 제어함으로써, 제1안테나를 주변 안테나의 영향 없이 정확하게 자신의 영역에 위치한 카지노 칩의 태그 정보를 판독하게 되는 것이다. 마찬가지로, 제2안테나(140)를 이용하여 해당 트레이 영역의 카지노 칩의 태그 정보를 판독할 경우, 단락 회로(133)의 단락 스위치는 오프(off)하고, 단락 회로(143)의 단락 스위치는 온(on)한다. 이로써, 제2안테나(140)만 안테나로서 동작하도록 하고, 제1안테나(130)는 안테나 특성을 제거하여, 제2안테나(140)에서 주변 안테나의 간섭없이 정확하게 해당 트레이 영역의 카지노 칩의 태그 정보를 정확하게 판독하게 되는 것이다.For example, when reading tag information of a casino chip in a specific tray area using the first antenna (eg, 130), the short switch in the short circuit 133 of the first antenna 130 is turned on. The short switch in the short circuit 143 of the second antenna (eg, 140) is turned off. Then, an antenna loop is formed in the first antenna 130, but the antenna loop is turned off in the second antenna 140, and the characteristics of the antenna are removed. In other words, it cannot function as an antenna. As a result, by controlling mutual interference between the two antennas, the first antenna can accurately read the tag information of the casino chip located in its area without the influence of the surrounding antennas. Similarly, when the tag information of the casino chip in the tray area is read using the second antenna 140, the short switch of the short circuit 133 is turned off and the short switch of the short circuit 143 is turned on. (on) As a result, only the second antenna 140 operates as an antenna, and the first antenna 130 removes the antenna characteristic, so that the tag information of the casino chip in the tray area can be accurately corrected without interference of the surrounding antennas in the second antenna 140. Will be read correctly.
여기서 각각의 안테나(130, 140)는 전체 트레이 영역(110)을 다시 영역 분할한 분할된 트레이 영역의 카지노 칩 태그 정보를 판독하는 역할을 한다.Here, each of the antennas 130 and 140 serves to read casino chip tag information of the divided tray area obtained by re-dividing the entire tray area 110.
한편, 도 5는 본 발명에 따른 카지노 테이블(100)에서 배팅 영역(120)에 올려지는 카지노 칩의 태그 정보를 판독하기 위한 카지노 칩 판독 안테나의 구성이다.5 is a configuration of a casino chip read 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.
카지노 테이블(100)의 각각의 배팅 영역의 하부에는 해당 배팅 영역에 올려지는 카지노 칩의 RFID 태그 정보를 판독하기 위해 복수의 안테나(161, 162, 163)가 설치된다. 여기서 본 발명에서는 3개의 안테나에 대해서만 도시 하였으나, 본 발명은 이것에 한정되는 것은 아니고 더 작거나 더 많은 개수의 안테나에 대해서도 동일하게 적용된다.A plurality of antennas 161, 162, and 163 are provided below the batting area of the casino table 100 to read RFID tag information of the casino chip placed on the batting area. Herein, although only three antennas are shown in the present invention, the present invention is not limited thereto, and the same applies to a smaller or larger number of antennas.
각각의 배팅 영역의 하부에 설치된 안테나(예를 들어, 151)는 매칭 회로와 급전을 위한 도체를 포함한다.An antenna (eg, 151) installed below each batting area includes a matching circuit and a conductor for feeding.
실제 카지노 테이블에는 많은 수의 배팅 영역이 존재한다. 카지노 테이블의 사이즈에 따라 그 개수는 상이할 수 있다. 게임 시 배팅 영역에 게임자가 카지노 칩을 올려놓으면 해당 배팅 영역의 하단에 마련된 안테나(151)에서 배팅 영역에 올려진 카지노 칩(예를 들어, 31 ~ 33)의 태그 정보를 읽어들인다. 이때, 상기 배팅 영역에 근접한 다른 배팅 영역의 하단에 마련된 안테나(152)도 해당 배팅 영역에 올려진 카지노 칩(예를 들어, 41 ~ 43)의 태그 정보를 읽어들인다.There are a large number of betting areas on the actual casino table. The number may vary depending on the size of the casino table. When a player places a casino chip in a betting area during a game, tag information of a casino chip (eg, 31 to 33) placed on the betting area is read from the antenna 151 provided at the bottom of the betting area. At this time, the antenna 152 provided at the lower end of the other batting area adjacent to the batting area also reads tag information of the casino chips (for example, 41 to 43) placed on the batting area.
이때, 제1안테나(예를 들어, 151)와 제2안테나(예를 들어, 152) 간에는 가지노 칩을 판독하기 위한 자장이 발생하는 데, 이때 각각의 안테나가 근접하게 설치되어, 각각의 안테나에서 발생한 자장이 근접한 안테나로 유기된다. 이로 인해 실제 카지노 칩이 없는 안테나도 동작을 하면, 아울러 카지노 칩은 다른 안테나로부터 발생한 자장에 의해 오동작을 하는 경우도 발생한다.At this time, a magnetic field for reading a gagnono chip is generated between the first antenna (for example, 151) and the second antenna (for example, 152), and each antenna is installed in close proximity to each antenna. The magnetic field generated by is induced by an adjacent antenna. As a result, when an antenna without an actual casino chip operates, the casino chip may also malfunction due to a magnetic field generated from another antenna.
따라서 이러한 문제점을 개선하기 위해서 본 발명은 도 5에 도시한 바와 같이, 각각의 안테나(151, 152, 153)에 각각 구비되는 도체의 주변에 자장을 차단하기 위한 자장 차단재(161, 162, 163)를 마련한다. Therefore, in order to improve such a problem, the present invention, as shown in Figure 5, the magnetic field shielding material (161, 162, 163) for blocking the magnetic field around the conductor provided in each of the antenna (151, 152, 153) To prepare.
여기서 자장 차단재(161, 162, 163)는 각각의 안테나에 마련되는 도체의 외주 면을 감싸도록 도체의 형상과 동일한 형상으로 설치되는 것이 바람직하다. The magnetic field shields 161, 162, and 163 are preferably installed 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.
상기 자장 차단재는 자장 유기를 차단할 수 있는 금속, 페라이트, 연자성체 중 어느 하나를 이용할 수 있다. 여기서 언급한 것 이외에 자장 차단이 가능한 알려진 모든 자장 차단재를 이용할 수 있다.The magnetic field blocking material may use any one of metal, ferrite, and soft magnetic material capable of blocking magnetic field organic matter. In addition to those mentioned here, any known magnetic barrier that can be shielded can be used.
자장 차단재와 도체는 자장 차단재 내부에 안테나가 삽입될 수 있는 형태로 하여, 자장 차단재 내부의 안테나에서 발생한 자장이 안테나 외부로 유출되어, 주변 안테나로 유기되는 것을 차단하거나 영향이 없는 범위 내로 최소화한다.The magnetic field shielding material and the conductor are formed in such a manner that the antenna can be inserted into the magnetic field blocking material, and the magnetic field generated by the antenna inside the magnetic field blocking material flows out of the antenna, thereby minimizing the induction into surrounding antennas or in an ineffective range.
