Description

Apparatus and Method for Collecting Parking Fee using Wireless Local Area Network}

The present invention relates to a parking fee collection device using a wireless LAN and a method thereof, and more particularly, to a parking fee quickly using a wireless LAN, which is a broadband communication between a wireless LAN base station device and a vehicle-mounted terminal device equipped with a smart card interface. The present invention relates to a parking fee collection apparatus using a wireless LAN for collecting the same, and a method thereof.

There are two types of parking tolls where parking toll collection systems are used: open parking and closed parking. The open parking toll parking lot means that there is no change in the fare system according to the parking time, that is, the parking toll only needs to pay a certain parking fee regardless of time or vehicle type. On the contrary, the closed parking lot means a parking lot that changes the fare system according to the vehicle type or the parking time, that is, charges are differently set according to the time or the vehicle type. Therefore, the closed parking toll does not collect the parking fee when the vehicle enters the parking lot, but pays the parking fee when leaving the parking lot. When entering a parking lot, record only the information necessary to set a parking fee.

The existing parking fee collection system is classified into a method using a radio frequency ID tag, an active short distance communication (DSRC), and an infrared method between a roadside base station device and a vehicle mounting device. Since they are narrowband communication, there is a problem that the speed of providing is slow even when used for a limited purpose of processing only parking fee collection.

In addition, the existing parking fee collection system has a weak point in security because there is no mutual authentication process between the base station and the terminal.

The present invention has been proposed to solve the above problems, by providing a broadband wireless LAN communication link between a wireless LAN base station device and a vehicle-mounted terminal device equipped with a smart card interface to provide a parking fee collection service at a high transmission speed. It is an object of the present invention to provide a parking fee collection device and a method using a wireless LAN.
