A block diagram showing the configuration.

2 and 3, an ETCS system providing a multi-lane service according to the present invention includes a vehicle-mounted device (On Board Unit: hereinafter referred to as 'OBU') 10, a roadside device (Radio Frequency Control Unit): (Hereinafter referred to as 'RFCU') 20, toll collection unit (Secure Application Module: referred to as 'SAM') 30, User Display Equipment (hereinafter referred to as 'UDE') 40, vehicle Separator (Advanced Optical Vehicle Detector: hereinafter referred to as 'AOVD') (50), Violation Car Photograph Equipment (hereinafter referred to as 'VCPE') (60), RFID Tag (70), Lane Sorter ( Lane Selection Equipment (hereinafter referred to as "LSE") (80), and a central control unit (Central Control Unit: referred to as "CCU") is characterized in that it comprises a 90.

The OBU 10 is mounted on each vehicle driving a toll road having one or more lanes, and stores vehicle information including identification information (ID), vehicle model information, a toll collection method, and the like, and the DSRC. As a device having a wireless communication means, the vehicle information transmission and fee settlement procedure is performed through the DSRC wireless communication with the RFCU (20). In particular, the OBU 10 includes a smart card (IC Card) in which personal information is registered in advance, and the smart card is unique to the vehicle owner through a website or offline visit such as the Korea Highway Corporation. It can be used by registering an RFID identification number, a vehicle registration number, and a use card number. When the OBU 10 receives the charging information from the RFCU 20, the charging information is assigned to the personal information of the smart card. The processing to withdraw from the balance is performed.

The RFCU 20 receives the vehicle information and the personal information of the OBU 10 through the DSRC wireless communication with the OBU 10 using the charging antenna 21 in the ETCS using the RF-DSRC scheme or the OBU. In step (10), the billing charge is transmitted.

The SAM 30 plays a role of initializing and approving the smart card mounted in the OBU 10 in the toll collection process under the control of the CCU 90, and the UDE 40 is one or more in each lane. It is installed to display the result of the toll collection process to each OBU 10 user under the control of the CCU (90).

The AOVD 50 serves to classify vehicle types by measuring the width and length of a vehicle passing through one or more lanes in each lane, and one or more VCPEs 60 are installed in each lane. If the vehicle model classified by 50 and the vehicle model of the OBU 10 obtained through the DSRC communication are different, the vehicle is determined to be a violating vehicle and serves to photograph the violating vehicle.

The RFID tag 70 is mounted on each vehicle driving a toll road having one or more lanes, and stores vehicle identification information including the vehicle number, and uses a CCU (RFID reader) installed in each lane. 90). In the above-described embodiment of the present invention, the RFID tag 70 is configured separately from the OBU 10 and is mounted on the vehicle. However, the RFID tag 70 may be integrally formed with the OBU 10. have.

The LSE 80 includes an RFID reader installed in each lane of a road to recognize an RFID tag 70 located in a predetermined communication area and receive vehicle information from the RFID tag 70. And transmitting the corresponding lane information to the CCU (90). In particular, the communication area of the RFID reader causes interference between a plurality of vehicles running in parallel between neighboring lanes or running with a tail in one lane. In order to prevent the problem, it is preferable to set the communication radius to an area shorter than the length of one vehicle and narrower than the width of one lane so as to cover only one lane. That is, the RFID applied to the present invention avoids interference between lanes by using 908.5-914 MHz, which is a different frequency band from 5795-5815 MHz and 5835-5855 MHz, which are used by DSRC. Since the area is limited, it can be used for lane separation.

The CCU (90) is connected to each of the components constituting the present invention determines the vehicle information and lane information of each vehicle passing through a plurality of lanes, whether or not illegal traffic, and performs a toll collection procedure in the case of a normal vehicle In case of a fraudulent vehicle, the vehicle controls a function of notifying the user by photographing the vehicle.

Therefore, the automatic toll collection system (ETCS) providing the multi-role service according to the present invention configured as described above is to summarize the main technical thoughts to start the automatic toll service by starting the DSRC communication between the OBU 10 and RFCU (20) Unlike the conventional ETCS service that performs the first, the LSE (80) installed in each lane is connected to the CCU (90) to obtain the vehicle number from the RFID tag 70 attached to the vehicle entering the lane in the toll processing process After acquiring the data including the vehicle number and the corresponding lane number information to the CCU 90, the second RFCU 20 receives the vehicle information from the OBU 10 of each vehicle and the CCU 90. Will be sent to. Subsequently, the CCU 90 compares the vehicle number and lane number inputted through the LSE 80 with the information of the OBU 10 inputted through the RFCU 20 to determine which lane the vehicle enters, and then, The automatic toll collection procedure is performed in conjunction with the other devices in one ETCS, thereby providing ETCS services in multiple lanes. At this time, the data code format input and output between the LSE 80 and the CCU 90 is configured as shown in FIG.

5 is a flowchart illustrating a detailed flow of an embodiment of an ETCS service method for providing a multi-car service according to the present invention.

Referring to FIG. 5, in a situation in which two or more vehicles enter a toll gate simultaneously through a plurality of lanes on a toll road such as a highway, first, an RFID tag (LSE 80 installed in each lane) is installed in each vehicle. When the vehicle number is obtained from 70) and the data including the vehicle number and the corresponding lane number information is transmitted to the CCU 90, the CCU 90 stores the data once (S501 to S502).

Subsequently, when the RFCU 20 receives vehicle information through the OBU 10 of each vehicle and the DSRC communication and transmits the vehicle information to the CCU 90 (S503 to S505), the CCU 90 transmits the LCU 80 through the LSE 80. By comparing the vehicle number and lane number input with the information of the OBU 10 input through the RFCU 20 to determine which lane each vehicle entered (S506), the CCU 90 according to the determination result Interaction with various devices such as AOVD (50), UDE (40), VCPE (60), RFCU (20) in the lane that matches the vehicle number to perform a processing procedure for toll collection (S507 ~ S525) In addition, the toll collection procedures S506 to S525 are well-known techniques in which the ETCS application interface standard is specified, and thus detailed description of the toll collection procedure will be omitted.

After the fare collection procedure is completed, the CCU 90 compares the vehicle type classification information input from the AOVD 50 and the vehicle information input from the OBU 10 in step S510 to determine whether the vehicle is fraudulent (S526). As a result of the determination, if a fraudulent vehicle occurs, the CCU 90 controls the VCPE 60 of the corresponding lane to photograph the violating vehicle (S527 ~ S528), and the UDE 40 installed in each lane is used. By notifying the user through the violations (S529 ~ S530) and all transactions are terminated (S531 ~ S532) and at the same time the communication between the RFCU 20 and the OBU (10) is terminated (S533).

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
