도 1은 ETC 시스템의 구성을 나타낸 블록도이다.1 is a block diagram showing the configuration of an ETC system.

도 1을 참조하면, 차량에 탑재되어 무선신호를 송수신할 수 있는 차량탑재장치(110)와, 상기 차량탑재장치와 무선으로 통신하기 위하여 톨게이트 및 도로 주변에 설치되는 노변기지국(RSU; Road Side Unit)(120)과, 톨게이트를 통과하는 차량의 높이, 길이, 폭을 스캔하여 차종을 감지하는 차종감지기(130)와, 상기 차종검지기(130) 및 노변기지국(120)과 연결되어 차량의 결제를 위하여 차량탑재장치로부터의 정보를 가공하고 데이터베이스화시키는 차선제어기(140)와, 상기 ETC 시스템을 통과하는 차량 중에서 결제가 되지 않거나 위반되는 차량을 촬영하기 위한카메라(150)와, 자동 결제를 마치고 그 결과를 차량운전자에게 제공하기 위한 요금정산결과 표시기(160)와, 상기 차선제어기(140)와 네트워크로 연결되어져 전체 차선제어기(140)로부터의 정보를 데이터 베이스화하고 모든 운영자 서버와 연계되어 관리하는 로컬서버(170)와, 신용카드를 이용한 요금정산시에 연결되어 인증절차 및 신용카드정보를 제공하는 신용카드 결제 시스템(180)을 포함하여 구성된다.Referring to FIG. 1, a vehicle mounting apparatus 110 mounted on a vehicle to transmit and receive a radio signal, and a roadside base station (RSU) installed around a toll gate and a road to wirelessly communicate with the vehicle mounting apparatus 120, a vehicle detector 130 for detecting a vehicle type by scanning a height, a length, and a width of the vehicle passing through the toll gate, and a vehicle detector 130 and a roadside base station 120 connected to the vehicle for payment In order to process and database the information from the onboard device to the lane controller 140, a camera 150 for photographing a vehicle that is not paid or violated from the vehicle passing through the ETC system, and the automatic payment after the result Is connected to the lane controller 140 and the network, the information is from the total lane controller 140 to the database And the local server (170) for managing all operators in conjunction with a server, connected to the settlement fee by credit card is configured to include a credit card payment system (180) for providing an authentication procedure, and credit card information.

상기와 같은 시스템에서의 통행요금 결제방식은 다음과 같은 순서로 이루어진다.Toll payment method in the above system is made in the following order.

도 2는 종래의 ETC 시스템에서의 결제방법의 데이터 흐름을 나타낸 흐름도이다.2 is a flowchart illustrating a data flow of a payment method in a conventional ETC system.

도 2를 참조하면, 차량이 유료도로의 톨게이트에 진입하여 노변기지국(120)의 통신영역에 들어서면, 노변기지국(120)에서 방송하는 초기화요구 메시지를 수신하여(S201), 응답메시지와 함께 차량탑재장치(110)의 일련번호 및 차량정보 등을 노변기지국(120)로 전송한다(S202).Referring to FIG. 2, when the vehicle enters the toll gate of the toll road and enters the communication area of the roadside base station 120, the vehicle receives an initialization request message broadcasted by the roadside base station 120 (S201), and the vehicle together with the response message. The serial number and vehicle information of the payload device 110 are transmitted to the roadside base station 120 (S202).

또한, 차량이 톨게이트에 진입하면, 차종감지기(130)에서는 차량의 길이, 높이, 폭 등을 스캔하여 차종을 조회하고, 조회된 차종정보를 차선제어기(140)로 전송한다(S203).In addition, when the vehicle enters the toll gate, the vehicle model detector 130 scans the length, height, width, and the like of the vehicle to inquire the vehicle model, and transmits the inquired vehicle model information to the lane controller 140 (S203).

또한, 상기 단계 S202에서 차량탑재장치(110)에서 전송한 차종정보를 차선 제어기(140)로 전송한다(S204).In addition, the vehicle type information transmitted from the vehicle mounting apparatus 110 in step S202 is transmitted to the lane controller 140 (S204).

상기 차종감지기(130)와 노변기지국(120)에서 전송하는 차량정보를 수신한 차선제어기(140)는 두 차량정보가 일치하는가를 확인한다(S205).The lane controller 140 receiving the vehicle information transmitted from the vehicle type detector 130 and the roadside base station 120 checks whether the two vehicle information is identical (S205).

또한, 상기 노변기지국(120)은 차량탑재장치(110)에 요금 결제를 위한 결제정보를 요청하고(S206), 응답메시지로 결제정보를 수신한 후(S207), 차선제어기 (140)로 전달한다(S208). 이때, 상기 결제정보에는 차량탑재장치(110)에 삽입되어 있는 스마트카드의 잔액정보와 개인정보 등을 포함한다.In addition, the roadside base station 120 requests the payment information for the payment on the vehicle mounting apparatus 110 (S206), after receiving the payment information in a response message (S207), and transmits to the lane controller 140. (S208). At this time, the payment information includes balance information and personal information of the smart card inserted in the vehicle-mounted device 110.

상기 결제정보를 수신한 차선제어기(140)는 스마트카드 잔액에서 결제요금을 차감하여 요금을 정산하고(S209), 정산결과를 노변기지국(120)에 전송하여(S210), 차량탑재장치(110)에 전달하도록 한다(S212). 또한, 차선제어기(140)의 데이터베이스에 요금정산결과를 업데이트하여 저장하도록 한다(S211).The lane controller 140 receiving the payment information settles the fee by subtracting the payment fee from the smart card balance (S209), and transmits the settlement result to the roadside base station 120 (S210). To be delivered to (S212). In addition, to update and store the result of the fare settlement in the database of the lane controller 140 (S211).

그리고, 상기 정산결과를 수신한 차량탑재장치(110)는 스마트카드의 잔액정보를 변경하여 업데이트하고(S213), 응답메시지를 노변기지국(120)로 전송하여 요금결제를 완료하도록 한다(S214).In addition, the vehicle mounting apparatus 110 receiving the settlement result changes and updates the balance information of the smart card (S213), and transmits a response message to the roadside base station 120 to complete the payment (S214).

상기 스마트 카드는 충전식 선불카드로써, 미리 일정 금액을 충전하고, 차량탑재장치(110)에 삽입하여 정산될 때마다 잔액을 차감하고, 잔액이 부족할 경우 지정된 장소에서 충전하여 반영구적으로 사용할 수 있다.The smart card is a rechargeable prepaid card, and charges a predetermined amount in advance, and the balance is subtracted each time it is inserted into the vehicle mounting apparatus 110, and when the balance is insufficient, the smart card can be charged semi-permanently.

그러나, 스마트카드를 이용하여 결제를 하는 방식은 우선 차량탑재장치에 스마트카드 삽입을 위한 장치가 추가로 구성되어야 함으로 차량탑재장치의 소형화에 한계가 있으며, 사용자가 잔액을 확인하여 충전해주어야 하는 불편함이 있다.However, the payment method using the smart card is limited to the miniaturization of the vehicle loading device because the device for inserting the smart card should be additionally configured in the vehicle loading device, and the user has to check the balance and recharge it. There is this.

따라서, 상기 스마트카드 대신에 이동통신 단말기를 이용하여 신용카드 결제를 하는 방식을 사용하기도 한다.Therefore, a method of making a credit card payment using a mobile communication terminal instead of the smart card may be used.

즉, 이동통신 단말기를 차량탑재장치에 연결하여, 톨게이트에 진입할 때, 이동통신 시스템 기지국과의 통신을 통하여 신용카드 결제 시스템(180)과 연계하여 사용자가 이동통신 단말기를 통해 버튼조작을 함으로써, 신용카드 결제 인증을 받아 요금을 정산하도록 하는 것이다.That is, when the mobile communication terminal is connected to the on-vehicle device and enters the toll gate, the user operates a button through the mobile communication terminal in connection with the credit card payment system 180 through communication with the mobile communication system base station. The credit card payment authorization is to be settled.

그러나, 상기와 같이, 이동통신 단말기를 이용한 신용카드 결제방식은 우선 톨게이트에 이동통신 시스템이 있어야만 하며, 신용카드 결제 시스템과의 사용자 인증과정이 복잡하며, 그 시간이 오래 걸리는 문제가 있다.However, as described above, the credit card payment method using the mobile communication terminal must first have a mobile communication system in the toll gate, and the user authentication process with the credit card payment system is complicated and takes a long time.

상기와 같은 문제를 해결하기 위해서, 본 발명은 ETC 시스템에서의 요금 정산을 하기 위하여 개인정보 및 차량정보와 신용카드 정보 등을 미리 차량탑재장치에 저장하고, 인증을 위한 특정 인증서 정보를 저장할 수 있도록 함으로써, 무선 공개키 인증방식을 이용하여 신속하게 결제를 할 수 있도록 하며, 차량탑재장치에 스마트 카드를 장착하지 않아도 되도록 하여 소형화를 이룰 수 있도록 하는 무선 공개키 기반 ＥＴＣ 결제방법을 제공함에 그 목적이 있다.In order to solve the above problems, the present invention is to store the personal information, vehicle information and credit card information, etc. in advance in the vehicle on-board device, and to store specific certificate information for authentication in order to settle the charge in the ETC system By providing a wireless public key-based ETC payment method that enables users to make a payment quickly by using a wireless public key authentication method and to achieve miniaturization by not having to install a smart card on a vehicle-mounted device. have.

이때, 상기 인증정보비교는 미리 정해진 인증서저보를 차량탑재장치 및 노변기지국에 저장하여 서로 같은 인증서인가를 확인하는 것으로, 무선 공개키 인증방식에 의한 것이다. 상기 인증서가 같으면 일단은 정상적인 사용자로인증을 하여 바로 결제 및 그 밖에 인증에 따른 동작을 수행할 수 있으며, 실제 결제는 나중에 처리하는 방식을 이용할 수 있다.At this time, the authentication information comparison is to store the predetermined certificate information in the vehicle-mounted device and the roadside base station to confirm whether the same certificate, by the wireless public key authentication method. If the certificate is the same, once the user is authenticated as a normal user, the payment and other operations can be performed according to the authentication, and the actual payment can be used later.

즉, 그 후에, 상기 노변기지국(120)에서 전송한 신용카드정보와 개인정보를 이용하여 차선제어기(140)에서는 신용카드 결제 시스템(180)에 접속하여 실제로 통행요금 이체 또는 결제를 완료하고(S313), 그 결과를 다시 노변기지국(120)을 통해 차량탑재장치(110)에 전송하여 알리고(S314), 상기 차량탑재장치(110)에서 응답메시지를 노변기지국(120)에 전송하여(S315), 요금정산을 마친다.That is, after that, by using the credit card information and personal information transmitted from the roadside base station 120, the lane controller 140 accesses the credit card payment system 180 to actually complete the toll transfer or payment (S313). ), And transmits the result back to the vehicle mounting apparatus 110 through the roadside base station 120 (S314), and transmits the response message from the vehicle mounting apparatus 110 to the roadside base station 120 (S315), Finish payment.

만약, 상기 노변기지국(120)에서 차량탑재장치(110)로부터 전송된 인증정보를 비교한 결과, 서로 일치 하지 않으면, 불법차량으로 간주하게 되며, ETC 시스템에 포함되어 구성되는 촬영수단인 카메라(150)를 이용하여 차량번호를 촬영하여 후에 과태료를 물도록 한다.If the roadside base station 120 compares the authentication information transmitted from the vehicle-mounted device 110 and does not match each other, it is regarded as an illegal vehicle and is a camera 150 which is a photographing means included in the ETC system. ) To take a picture of the car number and pay a penalty later.

이상에서 설명한 바와 같이, 본 발명에 따른 무선 공개키 기반 ＥＴＣ 결제방법은 ETC 시스템에서의 결제를 스마트카드가 없이 가능하도록 하여 차량탑재장치의 소형화를 가능하게 하며, 무선 공개키 기반의 인증방식을 이용하여 노변기지국 및 차량탑재장치간의 인증정보가 일치하기만 하면, 우선적으로 통행요금 정산결과를 사용자에게 알리고, 나중에 실제 신용카드정보를 이용한 정산을 하도록 함으로써 요금정산의 시간을 줄일 수 있는 효과가 있다.As described above, the wireless public key-based ETC payment method according to the present invention enables the vehicle-mounted device to be miniaturized by enabling payment in an ETC system without a smart card, and using a wireless public key-based authentication method. As long as the authentication information between the roadside base station and the vehicle-mounted device is identical, the toll settlement result is first notified to the user, and later, the settlement using the actual credit card information can reduce the time for the settlement of the fee.
