이하, 본 발명의 일실시예에 따른 RFID 리더기가 구비된 쇼핑 카트를 이용한 가격 정산 시스템의 정산 방법을 도 1 및 도 2를 참조하여 설명하도록 한다.Hereinafter, a method of calculating a price settlement system using a shopping cart equipped with an RFID reader according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
우선, 카트 본체(11)의 측면 개구(113)가 개방된 상태로 카트(1)가 매장 입구에 진입되면 제 1 스위칭 제어부(2)는 카트 진입을 감지하여 안테나(16)를 통해 스위치(15)로 개구 폐쇄 신호를 전송한다. First, when the cart 1 enters the store entrance with the side opening 113 of the cart body 11 open, the first switching controller 2 detects the cart entry and switches the switch 15 through the antenna 16. Transmits an opening closure signal.
스위치(15)는 수신된 개구 폐쇄 신호에 따라 차폐판 구동부(14)에 차폐판 이동 제어 신호를 출력하고, 차폐판 구동부(14)는 입력된 제어 신호에 따라 차폐판(13)을 이동시켜 차폐판(13)이 개구(113)를 폐쇄하도록 함으로써, 카트 본체(11) 내부의 상품 수납부(111)가 외부와 RF 통신이 이루어지지 않는 차단 상태가 되도록 한다. The switch 15 outputs a shield plate movement control signal to the shield plate driver 14 according to the received opening closing signal, and the shield plate driver 14 moves the shield plate 13 according to the input control signal to shield the shield plate. By allowing the plate 13 to close the opening 113, the product accommodating part 111 inside the cart body 11 is in a blocking state in which RF communication with the outside is not made.
이후, 구매자는 매장 내를 이동하면서 구매 상품을 상품 수납부(111)에 수납하게 되고, RFID 리더기(12)는 상품 수납부(111)에 수납되는 상품의 RFID 태그(T) 정보를 판독하여 태그 정보로부터 상품 정보를 검출하고, 설정된 시간이 지나면 검출된 상품 정보를 안테나(16)를 통해 정산 장치(4)로 전송한다. Subsequently, the purchaser stores the purchased product in the product storing unit 111 while moving in the store, and the RFID reader 12 reads the RFID tag T information of the product stored in the product storing unit 111 and tags the tag. The product information is detected from the information, and when the set time passes, the detected product information is transmitted to the settlement device 4 through the antenna 16.
이때, 카트 본체(11)의 측면에 형성된 개구(113)가 차폐판(13)으로 폐쇄되어 있기 때문에 카트 본체(11)의 하단에 설치된 RFID 리더기(12)는 카트 본체(11) 외부의 RFID 태그 정보는 판독하지 않게 됨으로써 가격 정산의 오류가 방지된다.At this time, since the opening 113 formed at the side of the cart body 11 is closed by the shield plate 13, the RFID reader 12 installed at the bottom of the cart body 11 is an RFID tag outside the cart body 11. By not reading the information, errors in price settlement are prevented.
정산 장치(4)는 안테나(16)를 통해 수신되는 각각의 상품 정보로부터 가격 정보를 추출하여 결제 금액을 1차 산출한다.The settlement device 4 extracts price information from each product information received through the antenna 16 to calculate the settlement amount first.
한편, 상품 구매를 마친 구매자가 쇼핑 카트(1)를 계산대로 이동시키면 제 2 스위칭 제어부(3)가 카트의 진입을 감지하여 안테나(16)를 통해 스위치(15)로 개구 개방 신호를 전송한다.On the other hand, when the purchaser who has finished purchasing the product moves the shopping cart 1 to the checkout, the second switching controller 3 detects the entry of the cart and transmits an opening opening signal to the switch 15 through the antenna 16.
그러면, 스위치(15)는 수신된 개구 개방 신호에 따라 차폐판 구동부(14)에 차폐판 이동 제어 신호를 출력하고, 차폐판 구동부(14)는 입력된 제어 신호에 따라 차폐판(13)을 이동시켜 차폐판(13)이 개구(113)를 개방시켜, 카트 본체(11) 내부와 외부 사이의 RF 통신 차단이 해제 되도록 한다. Then, the switch 15 outputs the shield plate movement control signal to the shield plate driver 14 according to the received opening opening signal, and the shield plate driver 14 moves the shield plate 13 according to the input control signal. The shield plate 13 opens the opening 113 so that the RF communication blockage between the inside and the outside of the cart body 11 is released.
이후, 정산 장치(4)는 카트 본체(11) 내부의 상품 수납부(111)에 수납된 상품의 태그 정보를 판독하고, 판독된 태그 정보로부터 상품 정보를 검출하여 결제 금액을 정산한다. 이때, 정산 장치(4)는 카트에 설치된 RFID 리더기(12)와의 통신은 중지하여 가격의 중복 정산을 방지한다.Thereafter, the settlement device 4 reads the tag information of the goods stored in the product accommodating portion 111 inside the cart main body 11, detects the product information from the read tag information, and calculates the settlement amount. At this time, the settlement device 4 stops communication with the RFID reader 12 installed in the cart to prevent the double settlement of the price.
또한, 정산 장치(4)는 RFID 리더기(12)로부터 전송된 상품 정보와 RFID 리더부(41)에서 검출된 상품 정보가 서로 일치할 경우에는 결제 금액을 정산하고, 일치하지 않을 경우에는 상품 정보 불일치 신호를 생성하여 이를 알린다.In addition, when the product information transmitted from the RFID reader 12 and the product information detected by the RFID reader unit 41 coincide with each other, the payment device 4 setstles a payment amount, and if it does not match, the product information mismatch. Generate a signal to advertise it.
또한, 본 발명의 다른 실시예에 따르면 제 1 스위칭 제어부(2)를 동작시키지 않고 개구(113)를 항상 폐쇄된 상태로 유지하여 상품 구매 동안에 카트(1) 내부의 상품 태그만이 판독되도록 하고, 계산대에 진입하면 구매자가 스위치를 수동으로 조작하여 개구(113)를 개방하도록 변형하여 실시할 수도 있다.Further, according to another embodiment of the present invention, the opening 113 is always kept closed without operating the first switching control unit 2 so that only the product tag inside the cart 1 is read during the product purchase. Upon entering the checkout counter, the purchaser may manually manipulate the switch to deform to open the opening 113.
비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정이나 변형을 하는 것이 가능하다. 따라서 첨부된 특허청구의 범위는 본 발명의 요지에서 속하는 이러한 수정이나 변형을 포함할 것이다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
