본 고안은 교통카드에 관한 것으로서, 보다 상세하게는 인피니온사의 SLE 66CL81P 집적회로칩을 포함하여 이루어지는 교통카드에 있어서, 안테나코일의 지름이 작고 권선수가 적은 경우에도 카드단말기와의 통신거리를 길게 확보할 수 있도록 하는 교통카드에 관한 것이다. The present invention relates to a traffic card, and more particularly, in a traffic card including an Infineon SLE 66CL81P integrated circuit chip, even if the diameter of the antenna coil is small and the number of turns is small, the communication distance to the card terminal can be secured. It's about a traffic card that lets you do that.

최근 버스나 전철 등의 교통수단을 이용함에 있어서 요금지불수단으로 알에프(RF: Radio Frequency) 방식의 교통카드가 널리 이용되고 있다. Recently, a radio frequency (RF) type of transportation card has been widely used as a means of paying a fare when using a transportation method such as a bus or a train.

알에프 방식의 교통카드는, 승객이 휴대하는 교통카드와 교통수단에 장착된 카드단말기 간에 발생하는 전자기유도현상을 이용하여 카드단말기로부터 전력을 공 급받는다. 따라서 교통카드에 별도의 전원을 포함하지 않고서도 교통카드와 카드단말기 간의 결제 프로세스를 비접촉식으로 수행할 수 있다는 장점이 있다. The RFID type transportation card receives electric power from the card terminal using electromagnetic induction generated between the passenger card and the card terminal mounted on the vehicle. Therefore, there is an advantage that the payment process between the transportation card and the card terminal can be carried out in a contactless manner without including a separate power source.

한편, 교통카드의 보급율이 충분히 높아짐으로써, 최근에는 단지 승차요금을 지불하는 기능을 수행하기 위한 물품이 아닌, 디자인을 강조한 패션 액세서리로서의 역할이 차츰 확대되고 있는 추세이다. On the other hand, as the penetration rate of traffic cards is sufficiently high, the role as a fashion accessory that emphasizes design is gradually expanding in recent years, not merely for carrying out a function of paying a fare.

도 3은 종래기술에 의한 교통카드의 전체적인 구성을 나타낸 도면이다. 3 is a view showing the overall configuration of a traffic card according to the prior art.

도 3에서 나타낸 바와 같이, 종래기술에 의한 교통카드는 교통카드칩(30)의 양 단자(301,302)에 안테나코일(31)의 양 단자가 접속되어 있고, 안테나코일(31)과 교통카드칩(30)은 신용카드형의 패키지(32)에 내장되는 형태가 일반적이다. As shown in FIG. 3, in the conventional traffic card, both terminals of the antenna coil 31 are connected to both terminals 301 and 302 of the transportation card chip 30, and the antenna coil 31 and the transportation card chip ( 30 is generally embedded in the credit card type package (32).

이 때에, 안테나코일(31)은 교통카드에 적정 전력을 공급하기 위하여 필요한 소정의 인덕턴스값을 얻을 수 있도록 크기 및 권선수(감은 횟수)가 결정된다. At this time, the antenna coil 31 is determined in size and number of turns (number of turns) so as to obtain a predetermined inductance value necessary to supply appropriate power to the traffic card.

만약 안테나코일(31)이 적절하지 않게 설계됨으로써 교통카드에 적정 전력을 공급할 수 없는 경우에는, 교통카드와 카드단말기 간의 통신가능거리가 짧아지므로, 정상적인 결제 프로세스를 수행할 수가 없게 된다. If the antenna coil 31 is not properly designed to supply adequate power to the traffic card, the communication distance between the traffic card and the card terminal is shortened, and thus, the normal payment process cannot be performed.

한편, 종래 기술에 의한 교통카드에서는 교통카드칩으로서 필립스사의 mifare MF1 IC S50 집적회로칩을 사용하여 왔다. 이 집적회로칩은 안테나코일의 지름과 권선수를 작게 하는 경우에도 교통카드와 카드단말기 간의 통신가능거리가 충분히 확보되므로, 도 2에서와 같이 고리형으로 성형한 케이스 내에, 가령 고리부(210)의 내부에 안테나코일을, 몸체부(220) 내부에 교통카드칩을 내장하는 식으로 패키징할 수도 있었다. 다만, 이 집적회로칩은 메모리 용량이 1kb에 불과하다는 한계가 있었다. On the other hand, in the conventional transportation card, Philips mifare MF1 IC S50 integrated circuit chip has been used as the transportation card chip. Since the integrated circuit chip has a sufficient communication distance between the traffic card and the card terminal even when the diameter of the antenna coil and the number of turns are reduced, the loop portion 210 is formed in a ring-shaped case as shown in FIG. The antenna coil in the interior, the body portion 220 could be packaged by embedding a traffic card chip inside. However, this integrated circuit chip has a limitation that the memory capacity is only 1kb.

이에, 메모리 용량이 8kb로 대폭 증가된 인피니온(Infineon technologies)사의 SLE 66CL81P 집적회로칩을 교통카드칩으로서 사용하고자 하는 시도가 최근 있었으나, 아래와 같은 문제점이 있었다. Thus, there have been recent attempts to use SLE 66CL81P integrated circuit chips of Infineon technologies, whose memory capacity has been greatly increased to 8 kb, as follows.

즉, 인피니온사의 집적회로칩을 교통카드칩으로서 사용하는 경우에는, 도 2에서 나타낸 바와 같이 사용자의 손가락 둘레 정도에 불과한 고리부(210) 내부에 수납될 정도의 지름 및 권선수를 가지는 안테나코일에 의해서는 교통카드의 동작에 필요한 전력을 충분히 공급받을 수 없게 된다. That is, in the case of using an integrated circuit chip of Infineon as a transportation card chip, as shown in FIG. 2, the antenna coil has a diameter and the number of turns enough to be stored in the ring portion 210 which is only about the circumference of the user's finger. By doing so, it is impossible to receive enough power for the operation of the transportation card.

교통카드는 카드단말기와 수 cm 정도 떨어져 있더라도 무리없이 동작할 필요가 있는데, 인피니온사의 집적회로칩에 의하게 되면 도 2에서 나타낸 바와 같은 고리형 패키지에 내장한 교통카드로는 통신가능거리가 그렇게 길게 확보되지 않으므로, 교통카드로서의 결제 프로세스를 정상적으로 행할 수 없는 문제점이 있었다. The traffic card needs to operate without difficulty even if it is several centimeters away from the card terminal. According to Infineon's integrated circuit chip, the communication card built in the annular package as shown in FIG. There is a problem that the payment process as a transportation card cannot be performed normally.

본 고안은 상기와 같은 문제점을 해결하기 위하여 착안된 것으로서, 인피니온사의 SLE 66CL81P 집적회로칩을 교통카드칩으로서 포함하여 이루어지는 교통카드에 있어서, 안테나코일의 지름이 작고 권선수가 적은 경우에도 카드단말기와의 통신거리를 길게 확보할 수 있도록 하는 교통카드를 제공하는 것을 목적으로 한다. The present invention is conceived to solve the above problems, in the traffic card comprising the Infineon SLE 66CL81P integrated circuit chip as a traffic card chip, even if the diameter of the antenna coil is small and the number of turns is small An object of the present invention is to provide a transportation card that allows a long communication distance.

상기와 같은 목적을 달성하기 위하여, 본 고안에 의한 교통카드는, 교통카드칩과, 안테나코일 및 커패시터를 포함하며, 상기 교통카드칩의 두 단자에 상기 안 테나코일의 두 단자 및 상기 커패시터의 두 단자가 병렬연결되어 이루어진다. In order to achieve the above object, a traffic card according to the present invention includes a traffic card chip, an antenna coil and a capacitor, and two terminals of the antenna coil and two terminals of the antenna coil at two terminals of the traffic card chip. The terminals are connected in parallel.

이하 도면을 참조하여 본 고안에 의한 교통카드를 더욱 상세하게 설명하기로 한다. With reference to the drawings will be described in more detail the traffic card according to the present invention.

도 1a는 본 고안에 의한 교통카드의 전체적인 구성을 나타낸 도면이다. Figure 1a is a view showing the overall configuration of the traffic card according to the present invention.

도 1a에서 나타낸 바와 같이, 본 고안에 의한 교통카드는 교통카드칩(10)과 교통카드칩(10)의 두 단자(101,102)에 두 단자가 각각 접속되는 안테나코일(12) 및 교통카드칩(10)의 두 단자(101,102)에 두 단자가 각각 접속되는 커패시터(11)를 포함하여 이루어진다. As shown in Figure 1a, the traffic card according to the present invention is an antenna coil 12 and a traffic card chip (12), each of which is connected to the two terminals (101, 102) of the traffic card chip 10 and the traffic card chip 10 ( And a capacitor 11 to which two terminals are connected to the two terminals 101 and 102, respectively.

도 1b는 도 1a의 교통카드칩을 더욱 자세히 나타낸 도면이다. FIG. 1B is a view illustrating the traffic card chip of FIG. 1A in more detail.

도 1b에서 나타낸 바와 같이, 본 고안에 의한 교통카드에 적용되는 교통카드칩인 인피니온사의 SLE 66CL81P 집적회로칩(10)은, 밀봉 패키징된 몸체(103) 안에 모든 회로가 구성되고, 단지 안테나코일의 두 단자와 접속되기 위한 RF 인터페이스의 두 단자(101, 102)만이 밀봉 패키징의 외부에 드러나 있음을 알 수 있다.As shown in Figure 1b, Infineon SLE 66CL81P integrated circuit chip 10, which is a traffic card chip applied to the traffic card according to the present invention, all the circuit is configured in the sealed package body 103, only of the antenna coil It can be seen that only two terminals 101, 102 of the RF interface to be connected with the two terminals are exposed outside of the sealed packaging.

도 1a의 안테나코일(12)은 안쪽 지름(Rin)과 바깥쪽 지름(Rout)을 갖도록 안테나 도선을 수 회 감아 이루어지는데, 도 1a의 실시예에서 본 고안에 의한 교통카드의 안테나코일은 안테나 도선을 n회 감는 경우에 n회의 권선수를 가지게 된다. 한편, 안테나코일은 3차원 공간에서 위로 감아 올려가는 이른바 "스프링형 코일"이 아니라, 2차원 평면상에서 안테나 도선이 안쪽 지름(Rin)으로부터 바깥쪽 지름(Rout)으로 서서히 커지도록 감아 나가는 이른바 "달팽이형 코일"이 된다. The antenna coil 12 of FIG. 1A is wound around the antenna lead several times to have an inner diameter Rin and an outer diameter Rout. In the embodiment of FIG. 1A, the antenna coil of the traffic card according to the present invention is an antenna lead If n is wound n times, it has n turns. On the other hand, the antenna coil is not a so-called "spring coil" that winds up in a three-dimensional space, but a so-called "snail" that winds up so that the antenna lead gradually grows from the inner diameter (Rin) to the outer diameter (Rout) on a two-dimensional plane. Mold coil ".

한편, 도 1a의 안테나코일(12)은 안쪽 지름(Rin)과 바깥족 지름(Rout)을 가 지는 완전한 원형이라야만 하는 것은 아니며, 타원 또는 찌그러진 원형으로 형성되더라도 안테나코일의 기능을 수행하는 데에는 큰 문제가 없다. 이 경우에도, 2차원 평면상에서 수 회 감아 나가는 달팽이형 코일의 형태로 성형하도록 하는 점은 마찬가지이다. Meanwhile, the antenna coil 12 of FIG. 1A does not have to be a perfect circle having an inner diameter Rin and an outer foot diameter Rout, and is large in performing the function of the antenna coil even when formed as an ellipse or a crushed circle. No problem. In this case as well, the point of forming in the form of a snail coil wound several times on a two-dimensional plane is the same.

도 1a의 실시예에서 본 고안에 의한 교통카드의 안테나 코일은, 지름이 약 0.15 내지 0.25mm인 도선을 약 3 내지 5회의 권선수를 갖도록 감아나가면, 안쪽 지름(Rin)이 약 20 내지 25mm, 바깥쪽 지름(Rout)이 약 23 내지 26mm가 된다. In the embodiment of Figure 1a, the antenna coil of the traffic card according to the present invention, when the winding of the wire having a diameter of about 0.15 to 0.25mm to have the number of turns about 3 to 5 times, the inner diameter (Rin) is about 20 to 25mm, The outer diameter Rout is about 23 to 26 mm.

본 고안에 의한 교통카드의 안테나 코일의 도선 지름과 안쪽 지름(Rin)및 바깥쪽 지름(Rout)은 반드시 저 수치를 가져야만 하는 것은 아니나, 본 고안에 의한 교통카드가 도 2와 같은 고리형 패키지의 내부에 장착되어야 한다는 점을 고려하여야 한다. 그렇다면, 고리부(210) 내에 안테나 코일이 포함되는 이상 일반인들의 손가락 굵기를 고려할 때, 안테나 코일의 안쪽 지름(Rin)과 바깥쪽 지름(Rout)은 위의 수치의 수 배 또는 수 분의 1 정도가 되도록 편차가 있도록 하지는 않는 것이 바람직하다. The conductor diameter, the inner diameter (Rin) and the outer diameter (Rout) of the antenna coil of the traffic card according to the present invention do not necessarily have low values, but the traffic card according to the present invention has a ring package as shown in FIG. Consideration should be given to the interior of the Then, in consideration of the finger thickness of the general public as long as the antenna coil is included in the ring portion 210, the inner diameter (Rin) and the outer diameter (Rout) of the antenna coil is several times or several times the above value. It is preferable not to make a deviation so that.

다음은, 교통카드칩(10)의 두 단자(101,102)에 안테나 코일(12)의 두 단자와 함께 접속되는 커패시터(11)에 대하여 살펴본다. Next, the capacitor 11 connected to the two terminals 101 and 102 of the transportation card chip 10 together with the two terminals of the antenna coil 12 will be described.

본 고안에 의한 교통카드에서, 커패시터의 용량은 교통카드와 카드단말기 간의 통신가능거리에 직접적인 영향을 미친다. 이는, 안테나 코일(12)과 커패시터(11)가 교통카드칩(10) 회로에 병렬로 연결됨으로써, 안테나 코일(12)의 인덕턴스값에 커패시터(11)의 커패시턴스값이 영향을 미치기 때문이다. In the traffic card according to the present invention, the capacity of the capacitor directly affects the communication distance between the traffic card and the card terminal. This is because the antenna coil 12 and the capacitor 11 are connected in parallel to the traffic card chip 10 circuit, whereby the capacitance value of the capacitor 11 affects the inductance value of the antenna coil 12.

표 1은 본 고안에 의한 교통카드에서 안테나 코일의 권선수와 커패시터의 용량 및 교통카드와 카드단말기 간의 통신가능거리와의 상관관계를 실험을 통하여 측정한 일실시예의 결과값을 정리한 표이다. Table 1 summarizes the results of one embodiment measured through the experiment the correlation between the number of windings of the antenna coil and the capacity of the capacitor in the traffic card according to the present invention and the communication distance between the traffic card and the card terminal.

(안테나코일의 도선굵기는 0.19mm, 안쪽 지름(Rin)은 약 22.5mm, 바깥쪽 지름(Rout)은 약24.1mm, 교통카드칩은 인피니온사의 SLE 66CL81P 집적회로칩, 커패시터는 액시얼 타입(axial type)의 커패시터이다.)(The wire diameter of the antenna coil is 0.19mm, inner diameter (Rin) is about 22.5mm, outer diameter (Rout) is about 24.1mm, Infinion's SLE 66CL81P integrated circuit chip, capacitor is axial type (axial type).)

Figure 112006093745109-utm00001
Figure 112006093745109-utm00001

표 1의 실험 1을 통하여, 교통카드칩의 두 단자에 안테나코일만 접속시키면 통신단말기는 교통카드를 단지 인식만 할 뿐, 정상적인 결제 프로세스를 할 수 없게 되는 종래 기술의 문제점을 확인할 수 있었다. Through experiment 1 of Table 1, when only the antenna coil is connected to the two terminals of the traffic card chip, the communication terminal can recognize the problem of the prior art that only recognizes the traffic card and cannot perform the normal payment process.

실험 2와 같이 권선수 4회, 커패시터 용량을 120pF으로 한 경우에 통신가능거리가 35 ~ 40mm 가량이 되는 가장 좋은 결과를 얻을 수 있었다. 이러한 통신가능거리는 일반적인 교통카드 사용환경에서 문제없이 결제 프로세스를 수행할 수 있는 거리이다.As shown in Experiment 2, the best results were obtained when the number of windings and the capacity of the capacitor were 120pF, and the communication distance was about 35 to 40mm. This communication distance is a distance in which a payment process can be performed without a problem in a general transportation card use environment.

커패시터 용량은 안테나코일의 도선굵기, 권선수, 안쪽 지름(Rin) 및 바깥쪽 지름(Rout)과 상관관계를 가지는데, 바람직하게는 100 내지 150pF의 범위 내에 속하도록 용량을 정하는 것이 좋다. The capacitor capacity is correlated with the conductor thickness of the antenna coil, the number of turns, the inner diameter Rin, and the outer diameter Rout. Preferably, the capacitance is set to fall within the range of 100 to 150 pF.

또한, 커패시터의 타입은 액시얼 타입(axial type)의 커패시터가 되도록 하는 것이 바람직하다. 다만, 본 고안에 의한 교통카드를 구성하기 위하여 사용되는 커패시터는 액시얼 타입만으로 한정되는 것은 아니다.In addition, it is preferable that the type of the capacitor be an axial type capacitor. However, the capacitor used to construct the traffic card according to the present invention is not limited to the axial type alone.

한편, 실험 3에서와 같이 권선수를 증가시켜 13 ~ 14회가 되도록 한 경우에는 오히려 통신가능거리가 20mm 이하로 떨어지게 되는 결과를 얻었다. 즉, 권선수를 증가시키는 경우에 통신가능거리가 오히려 짧아지는 역효과를 얻는 것이다. On the other hand, as in Experiment 3, when the number of turns was increased to 13 to 14 times, the result was that the communication distance fell to 20 mm or less. In other words, when the number of turns is increased, the adverse effect of shortening the communication distance is obtained.

도 1c는 본 고안에 의한 교통카드의 블록도이다. Figure 1c is a block diagram of a traffic card according to the present invention.
