Description

AUTOMATION TOLL COLLECTION METHOD AND SYSTEM USING PORTABLE TERMINAL EQUIPMENT}

The present invention relates to an intelligent traffic control system, and more particularly, to an automatic billing method and system using a portable terminal.

In general, the highway toll collection system uses a magnetic card to pay the toll directly.

In the conventional toll collection system, as shown in the operation flowchart of FIG. 1, when the driver enters the highway, the driver draws a card issued from the magnetic card ticket machine installed at the entrance of the toll gate, and when the driver enters the highway, the driver records the information recorded on the card at the exit of the toll gate. To pay the toll.

However, in the conventional toll collection system, the driver has to stop the vehicle at the ramp to draw a card and stop the vehicle at the toll gate to pay the toll when leaving the toll gate. There was a problem causing.

By the way, intelligent transport systems (ITS) have been proposed to enable services such as automatic toll collection, vehicle identification, vehicle management, and route guidance.

Intelligent transportation systems can use dedicated short range communication (DSRC) to provide services that automatically settle fees when using paid facilities such as highways and parking lots.

Short-range dedicated communication (DSRC) is a standard for transmitting and receiving desired information in both directions through a wireless medium between an on-board unit / equipment (OBU) and a roadside equipment (RSE).

The communication link between the roadside beacon and the vehicle is made up of short- and medium-range wireless links using radio frequencies, and includes automatic toll collection, vehicle identification, freight and used vehicle management systems, on-vehicle information systems, and route guidance systems. Used for communication.

A short-range link usually means a communication distance of about 10 meters, uses a directional antenna, and is mainly used for electronic toll collection (ETC) systems.

Medium-range link usually means a communication distance of about 70m and is used for providing traffic information and driving guidance.

In addition, the highway toll collection system using the IC card is configured to be equipped with a card controller that can read the IC card in the vehicle and a toll collection device for collecting tolls on the highway access road.

Therefore, the toll collection system reads the information on the card from the card controller mounted on the vehicle when the vehicle enters the highway and calculates the toll through the toll collection device and the wireless link.

In the toll collection system, the mobile terminal having the highway toll settlement function determines the position between the toll stations based on the unique data of the corresponding base station transmitted from each base station and calculates the tolls of the highway driving section by determining the position. Do it.

In addition, the highway, subway, national railway, parking lot, credit card bill payment service using a mobile phone, the existing ETC equipment and RF card in parallel to settle the highway fee, credit transaction method using a mobile phone, bus and subway using a mobile phone Is done in a way.

This service is provided by the mobile terminal and the separate terminal connected to the RS-232 port when the toll gate enters the target toll gate and transmits MIN information (mobile phone number) embedded in the mobile phone to the roadside base station (RSE). By storing the MIN information, the home memory of the mobile carrier is compared with the MIN information of both toll gates to calculate the highway toll and then charge the mobile phone usage fee.

However, in the case of adopting the DSRC method, the user must use an OBU and a card to install additional equipment such as the vehicle-mounted device in the vehicle. There is a disadvantage in that it is not suitable.

In addition, the toll collection system using the conventional IC card has the disadvantage of causing an economic burden by requiring an RF card controller connected to a separate smart card in the vehicle.

In addition, the conventional payment service using a mobile phone has a disadvantage in that a security problem occurs when the MIN information is leaked by transmitting the MIN information (mobile phone number) stored in the mobile phone to the roadside base station to pay a fee.

Accordingly, the present invention provides an automatic billing method using a portable terminal created to automatically pay a fee using the IC card for electronic money embedded / mounted in the portable terminal in order to improve the conventional problems and The purpose is to provide a system.
