Description

번호판 인식을 이용한 전기 자동차의 충전 및 결제 시스템{ELECTRIC VEHICLE CHARGING AND VILLING SYSTEM USING LICENSE PLATE RECOGNITION}ELECTRIC VEHICLE CHARGING AND VILLING SYSTEM USING LICENSE PLATE RECOGNITION}

본 발명은 전기 자동차의 번호판 인식을 통해 등록된 사용자의 전기 자동차임을 판단하여 전기 자동차의 충전 및 결제가 이루어지는 번호판 인식을 이용한 전기 자동차의 충전 및 결제 시스템에 관한 것이다. The present invention relates to a charging and payment system for an electric vehicle using license plate recognition in which charging and settlement of the electric vehicle are performed by determining that the electric vehicle is registered by the license plate recognition of the electric vehicle.

전기자동차(EV;Electric Vehicle)란, 기존 자동차들이 엔진과 전기모터를 같이 쓰는 하이브리드와 달리 전기모터만으로 움직이는 순수 전기차로 배기가스와 소음, 진동이 적어 조용하고 쾌적한 운행이 가능한 친환경 차량이다. Electric vehicles (EVs), unlike hybrids in which existing cars share engines and electric motors, are pure electric cars that move only by electric motors.

기존의 전기자동차를 충전을 위해서는 완속, 급속, 휴대용 충전기 형태인 플러그인 충전방식이 있었으나 자계 커필링에 의한 파워전달이 가능하여 주차만으로 자동충전이 가능한 무선충전방식이 도입되고 있다. In order to charge the existing electric vehicle, there was a plug-in charging method, which is a slow, rapid, and portable charger type, but a wireless charging method that enables automatic charging only by parking is available because power can be transmitted by magnetic field filling.

이는 스마트폰의 무선충전방식처럼 자기공명에 의한 무선충전이 가능하여 충전케이블을 소지하고 다녀야하는 전기차 운전자의 불편함을 보완해주는 충전방식이다. This is a charging method that compensates for the inconvenience of the electric vehicle driver who has to carry a charging cable by enabling wireless charging by magnetic resonance like the wireless charging method of a smartphone.

또한, 외부 먼지나 눈 등에 의한 오염이 쉽고, 기온에 따라 뜨겁거나 차가운 플러그를 이용해야 하는 단점을 보완하며 여성이나 노약자가 다루기에는 다소 무게감 있는 플러그의 불편함을 해소해준다. In addition, it is easy to be polluted by external dust or snow, and to compensate for the disadvantage of using a hot or cold plug depending on the temperature, and eliminates the inconvenience of a rather heavy plug for women or the elderly.

이와 같은 무선충전 시스템은 도 1에 도시한 바와 같으며, 이는 장기적으로 쇼핑을 하는 도중에 주차장에서 충전이 가능해진다. Such a wireless charging system is shown in Figure 1, which can be charged in the parking lot during the long-term shopping.

그러나, 기존에 무선 충전을 통해 사용자의 편의를 제공하나 결제를 별도로 진행함으로써 사용자가 불편을 겪음에 따라 전기 자동차의 충전과 결제가 동시에 진행하여 사용자에게 편리함을 제공할 수 있는 시스템이 요구된다. However, in the past, a system for providing convenience to a user by providing a user's convenience through wireless charging but proceeding with a payment separately and having a user's inconvenience, while simultaneously charging and paying an electric vehicle is required.

판단부(230)는 추출된 전기 자동차의 번호를 데이터 베이스부(220)에 저장된 사용자 정보와 매칭하여 충전가능 여부를 판단한다. 즉, 추출된 전기 자동차의 번호가 기 등록된 사용자 정보에 포함되어 있는 전기 자동차인지 판단하여 충전 가능 여부를 확인한다.The determination unit 230 determines whether or not charging is possible by matching the extracted electric vehicle number with user information stored in the database unit 220. That is, it is determined whether the number of the extracted electric vehicle is the electric vehicle included in the pre-registered user information and whether it is possible to charge.

기등록된 사용자의 전기 자동차인 경우, 결제카드 정보를 포함하고 있으므로, 충전이 가능하나, 기 등록되지 않은 사용자의 전기 자동차인 경우 충전이 불가할 수 있으므로 이에 대한 정보를 사용자에게 전달한다. In the case of an electric vehicle of a registered user, since the payment card information is included, charging is possible, but in the case of an electric vehicle of an unregistered user, charging may be impossible.

이와 같은 이유로 충전이 불가한 경우 데이터 베이스부(220)에 등록되지 않은 정보이므로, 서버(200)는 충전 단말기(100)의 표시부(미도시)를 통해 해당 사항을 안내하고, 사용자 정보가 등록되면 충전 가능 상태로 전환될 수 있다. If charging is not possible for this reason, since the information is not registered in the database unit 220, the server 200 guides the corresponding information through a display unit (not shown) of the charging terminal 100, and user information is registered. Can be switched to a chargeable state.

또한, 전기 자동차와 사용자가 일치하는지 확인하기 위해 데이터 베이스부(220)에 저장된 사용자의 연락처로 인증 메시지를 전달하여 응답에 따라 전기 자동차의 충전 여부를 판단한다. In addition, in order to check whether the electric vehicle matches the user, an authentication message is transmitted to the contact information of the user stored in the database unit 220 to determine whether the electric vehicle is charged according to the response.

이때, 인증 메시지는 휴대 단말기(300)의 어플리케이션(310)을 통한 팝업창으로 전달 받을 수 있다. In this case, the authentication message may be delivered to the pop-up window through the application 310 of the mobile terminal 300.

제2 통신부(240)는 판단부(230)에서 판단된 정보를 충전 단말기(100) 및 사용자의 휴대 단말기(300) 중 어느 하나 이상으로 정보를 전달한다. The second communication unit 240 transfers the information determined by the determination unit 230 to any one or more of the charging terminal 100 and the user's portable terminal 300.

충전 단말기(100)로 충전 가능 정보가 전달되면 충전 단말기(100)는 전기 자동차 충전이 이루어지고, 휴대 단말기(300)로 전달된 정보를 통해 비용은 카드 승인으로 결제가 이루어지도록 한다.When the chargeable information is transferred to the charging terminal 100, the charging terminal 100 is charged with the electric vehicle, and the payment is made by the card approval through the information transmitted to the portable terminal 300.

휴대 단말기(300)는 서버(200)와 연동되는 어플리케이션(310)이 설치되어 있으며, 어플리케이션(310)을 통해 사용자 정보를 등록할 수 있으며, 나아가, 어플리케이션(310)을 통해 카드 결제 승인, 전기 자동차가 충전한 충전소 위치, 충전 시기, 및 충전 금액 중 어느 하나 이상을 포함하는 충전 정보를 모니터링할 수 있다.The mobile terminal 300 has an application 310 that is linked with the server 200 is installed, can register the user information through the application 310, further, through the application 310 card payment approval, electric vehicle The charging information including any one or more of the charging station location, charging time, and the amount of charge can be monitored.

상기와 같은 구성으로 번호판 인식을 이용한 전기 자동차의 충전 결제 방법은 도 3과 같다. The charging and charging method of the electric vehicle using the license plate recognition as described above is as shown in FIG.

먼저, 영상 입력부(110)를 통해 전기 자동차를 촬영하여 서버(200)에 전달한다(S100). 이때, 촬영된 전기 자동차는 번호판을 포함한 상태이어야 한다. First, the electric vehicle is photographed through the image input unit 110 and transmitted to the server 200 (S100). At this time, the photographed electric vehicle should be in a state including a license plate.

이어, 서버(200)에서 전기 자동차의 번호판을 인식한다(S200). 즉, 번호판을 포함한 전체 이미지에서 번호판을 추출하여 해당 숫자 및 문자를 인식한다. 이때, 전기 자동차의 번호판을 인식하는 방법은 도 4에 도시한 바와 같다. Subsequently, the server 200 recognizes the license plate of the electric vehicle (S200). That is, the license plate is extracted from the entire image including the license plate to recognize the numbers and letters. At this time, the method of recognizing the license plate of the electric vehicle is as shown in FIG.

로컬라이제이션부(211)를 통해 전기 자동차의 전체 이미지 중 특정 이미지를 추출한다(S210). 본 발명의 실시예에서 특정 이미지는 번호판에 해당되므로, 번호판 이미지를 추출한다. The localization unit 211 extracts a specific image from the entire image of the electric vehicle (S210). In the embodiment of the present invention, since the specific image corresponds to the license plate, the license plate image is extracted.

그리고, 레코그니션부(212)가 추출된 번호판 이미지 중 문자 및 숫자에 해당되는 글자를 이미지가 아닌 캐릭터(characters)로 인식한다(S220). In addition, the recording unit 212 recognizes letters corresponding to letters and numbers among the extracted license plate images as characters rather than images (S220).

그리고, 리어셈블리부(213)가 최종 필요한 정보로 글자를 재배열하여 전기 자동차의 번호판을 글자로 인식한다(S230). Then, the rear assembly unit 213 rearranges the letters with the last necessary information to recognize the license plate of the electric vehicle as the letters (S230).

여기서, 로컬라이제이션부(211)와 레코그니션부(212)는 합성곱 신경망(Convolutional Neural Network) 모델을 통해 딥러닝하여 전기 자동차의 번호판 이미지의 인식율을 높인다. Here, the localization unit 211 and the recording unit 212 deep learning through a convolutional neural network model to increase the recognition rate of the license plate image of the electric vehicle.

이어, 인식된 번호판과 사용자 정보를 매칭하여 충전 가능 여부를 판단한다(S300). 이를 통해 사용자를 인증할 수 있다. Subsequently, it is determined whether charging is possible by matching the recognized license plate with user information (S300). This allows you to authenticate users.

예컨대, 인식된 번호판의 번호에 따른 사용자 정보에 저장된 사용자의 연락처로 인증 메시지가 전달되는 경우, 사용자는 인증 메시지를 통해 사용자가 운전여부를 파악 할 수 있어 사용자가 인증 메시지에 대해 응답을 하는 경우 충전이 가능하나, 인증 메시지에 대한 응답이 없는 경우 사용자는 전기 자동차의 도난, 또는 위치를 파악할 수 있고, 이를 통해 충전이 가능하지 않을 수도 있다. For example, when the authentication message is delivered to the user's contact information stored in the user information according to the recognized license plate number, the user can determine whether the user is driving through the authentication message and the user charges when the user responds to the authentication message. This may be possible, but if there is no response to the authentication message, the user may determine the theft or location of the electric vehicle, and may not be able to charge it.

즉, 충전이 가능하지 않은 경우는 미리 등록되지 않은 사용자의 전기 자동차이거나, 인증 메시지에 대한 사용자의 응답이 이루어지지 않은 경우에 충전이 가능하지 않을 수 있다. That is, when charging is not possible, it may be an electric vehicle of a user who is not registered in advance, or charging may not be possible when a user's response to an authentication message is not made.

여기서, 사용자 정보는 사용자의 휴대 단말기(300)에 설치된 어플리케이션(310)을 통해 입력할 수 있으며, 휴대 단말기(300)에 설치된 어플리케이션(310)은 서버(200)와 연동된다.  Here, the user information may be input through an application 310 installed in the user's portable terminal 300, and the application 310 installed in the portable terminal 300 may be linked with the server 200.

즉, 휴대 단말기(300)를 통해 입력된 정보는 서버(200)의 데이터베이스부(220)에 저장된다. That is, the information input through the mobile terminal 300 is stored in the database unit 220 of the server 200.

이어, 충전 가능 여부 판단 정보를 충전 단말기(100) 및 사용자의 휴대 단말기(300)에 전달한다(S400). Subsequently, the charging determination information is transmitted to the charging terminal 100 and the user's portable terminal 300 (S400).

마지막으로, 충전 단말기(100)를 통해 전기 자동차의 충전이 이루어지고, 사용자의 휴대 단말기(300)를 통해 충전 비용을 결제한다(S500). Finally, the charging of the electric vehicle is made through the charging terminal 100, and the charging cost is paid through the user's portable terminal 300 (S500).

본 발명의 실시예에서 서버(200)와 휴대 단말기(300)가 연동되어 결제가 이루어지기 위해서 서버(200)가 온라인 결제 서비스(미도시)와 연계되어야 함은 자명함으로 이에 대한 상세한 설명은 생략 하도록 한다.
