4 shows a settlement system using a board unit applied to the present invention, the GPS module 140, the cellular module 150, or the DSRC module 110 can know the position and the traveling direction of the vehicle. When the gantry detects the passage through the virtual toll gate based on the location information, the fee is settled using the mobile communication network.

Information for settlement is sent to the VAN network for settlement of fees. At this time, the toll collection fee will be settled in the SIM card or IC card in the board unit 100.

In addition, the DSRC / RF module 110 is provided for compatibility with the existing toll collection system (high pass or TCS).

The operation of the settlement system using the vehicle board unit 100 as described above will be described with reference to the flowchart of FIG. 5.

First, after mounting the board unit 100 on which the GPS module 140 and the cellular module 150 are mounted in the vehicle, and then entering the vehicle in the communication area where the gantry is installed, the RSE unit (not shown) installed in the gantry (Gantry) The mutual authentication and passage information is confirmed by wireless communication using the DSRC / RF 110 or the Bluetooth module 120 between the vehicle and the board unit 100 of the vehicle.

In this case, when the remaining amount accumulated in the IC card of the board unit 100 is insufficient, it is recognized as a violation vehicle and put on the blacklist for separate management or processing.

FIG. 6 is a diagram illustrating a method of determining vehicle progress using the GPS of FIG. 3. The GPS module 140 is a device for identifying a position of a vehicle using longitude and latitude within a range of several meters. Using the module 140, the location of the vehicle is always determined, and after passing through the pre-stored entrance toll gate, the location coordinate is determined. You pay the toll through.

For example, if it is determined that the vehicle has moved to the C region through the A region using the GPS module 140 embedded in the board unit 100, the vehicle is considered to have passed through the toll gate A. If it is found that the vehicle moves from the D region to the F region through the E region, the vehicle is considered to have passed through the toll gate B and pays the toll through the mobile communication network.

The payment method using the mobile communication network may be charged in the form of postpay through the mobile communication network or may use a separate mobile communication payment means such as financial information embedded in the SIM module 130. Therefore, the location of the vehicle or the passage of the toll gate is determined by the coordinate calculation by GPS, and the payment of the toll is made through a mobile communication network separate from the GPS.

On the other hand, Figure 7 is shown to explain the vehicle progress determination method using the mobile communication network of Figure 3, unlike the above-described method using the GPS is a wireless communication unit of the mobile communication network for mobile communication Take advantage of the fact that it consists of cells.

As shown in the figure, the mobile communication network is composed of a plurality of adjacent cells. As the vehicle crosses the boundary between the cells, a handover occurs and the information indicates the direction of the vehicle.

For example, if the vehicle is moved between the cells A42, A32, A12, A21, etc. facing the road in FIG. 7, it can be seen that the vehicle has passed through the toll gate A. Also, if the mobile communication network can know that the cell has passed through the cells B33, B13, B22, etc., the vehicle may be considered to have passed through the toll gate B.

In addition, the past route of the vehicle by the mobile communication network is stored in the VLR (Visitor Location Register), so it is easy to know where the vehicle has passed and where it started.

In FIG. 8, a mobile communication network is illustrated. Cell information that a vehicle has passed so far is stored in a VLR (Visitor Location Register). Therefore, you can collect a fee based on the information passed by the vehicle.

9 and 10 illustrate a method of paying a toll using a mobile communication network. The collection of tolls is payable from a prepaid amount stored in an IC card in the board unit 100 as in the existing system and a proposed SIM. There is a method using module 130.

The present invention provides a method of imposing a toll on a board unit 100 user in a postpaid form with an ID or a unique number of a mobile communication subscriber stored in a SIM module 130 module.

According to the contract between the toll collection agency and the mobile telecommunication company, the mobile telecommunication company issues the SIM module 130 to the subscriber for the purpose of collecting the toll only, and then transfers the SIM module 130 to the proposed board unit 100. Mount it. The SIM module 130 stores IDs or unique numbers of mobile subscribers or financial data for electronic payment using mobile communication.

Of course, if the SIM module 130 is not used, such subscriber information may be stored in the CPU memory area of the board unit 100.

Toll collection is the board unit 100 first calculates the toll, read the user information stored in the SIM module 130 (2), or read the user's unique number stored in the memory area of the central processing unit 180 ( 2 '), when the user information and the toll amount information are transmitted to the mobile communication company through the mobile communication network using the cellular module 150 (3), the mobile communication company transmits the information to the subscriber as well as the mobile communication fee based on this information. Tolls will be charged in the form of postpay (4). Once the tolls charged are collected (4), the mobile carrier will forward them to the toll collector (5). Alternatively, the toll may be paid in real time instead of postpay using financial information embedded in the SIM module 130.

The cellular module 150 and the SIM module 130 used in the proposed board unit 100 are used only for toll payment, not the role of a mobile communication terminal (ie, a voice communication device such as a mobile phone). Therefore, the mobile communication company does not assign a mobile communication phone number to the SIM module 130 or the board unit 100, but manages by assigning a unique number or a special identification number.

In addition, the board unit 100 should determine whether to pay by using mobile communication or the amount stored in the built-in IC card or request the user to determine.

FIG. 11 is a view illustrating a vehicle progress determination method and a toll collection method using communication with an RSE. In the current toll collection system, the board unit 100 uses RF communication with an antenna of a gantry structure installed on a toll gate. Data exchange and toll collection take place.

However, this method has the disadvantage of expensive structure installation cost and antenna. To compensate for this, a device called RSE or Beacon is installed near the toll gate so as to communicate with the board unit 100. The board unit 100 receives the location information from the RSE installed in the entrance toll gate currently passing through and compares the location information received from the RSE of the exit toll gate to grasp the information of the road through which the vehicle passed, thus calculating the toll. It is possible. The roadside RSE is communicated with the board unit 100 using the DSRC / RF module 110 or the Bluetooth module 120. The Bluetooth module 120 is a short-range wireless communication module, may be included in the cellular module, or may be embedded in the board unit 100 as a separate module.

The tolls calculated while passing between each RSE are paid at the prepaid amount embedded in the IC card through the exit RSE, charged in the form of post-paid through the mobile communication network, or additional mobile communication such as financial information embedded in the SIM module 130. Payment means can be used.

Meanwhile, as a method of downloading various traffic information, information in IDS (Information Database System) is transmitted to the VAN. The information stored in the VAN is sent to the cellular base station to which the vehicle currently belongs, and the base station transmits the information to the cellular module 150 of the board unit 100 installed in the vehicle. The board unit 100 receives the information in real time by sending the information to the display device.

The usage fee for the provided traffic information may be charged in the form of postpay through a mobile communication network or a separate mobile payment means such as financial information embedded in the SIM module 130 may be used.

While specific embodiments of the present invention have been described and illustrated above, it will be apparent that the present invention may be embodied in various modifications by those skilled in the art. Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, but should fall within the claims appended to the present invention.
