Description

INTERNET INFORMATION SERVICE APPARATUS USING DEDICATED SHORT RANGE COMMUNICATION NETWORK}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to intelligent transport systems (ITS), and more particularly, to an Internet information service apparatus using a short-range wireless dedicated communication network.

As the number of vehicles increases, wireless communication technology is integrated into traffic-related systems in order to suppress traffic congestion and the increase in logistics costs.

Conventionally, FM-DARC wireless communication, beacon wireless communication, cellular wireless communication, IMT-2000 wireless communication, and the like have been proposed as wireless communication technologies for incorporating traffic-related systems.

The FM-DARC wireless communication method is a method of transmitting digital data using an existing FM broadcast channel. Since the transmission speed is up to 16kbps and the communication cell size is several tens of Km, the digital transceiver is implemented because it uses a wide area service and an existing broadcast channel. There is an easy advantage.

The beacon wireless communication method can provide convenience to the user through automatic parking fee settlement and parking available location designation when using the parking service because the two-way communication between the vehicle terminal and the roadside base station is possible.

The cellular wireless communication method uses a circuit communication method for providing a voice service to a vehicle driver even when moving.

The IMT-2000 wireless communication method is being developed as a communication method capable of providing a packet data service as well as a voice service.

However, the conventional technology using the FM-DARC wireless communication method is limited by the one-way service provided only downlink because it uses a broadcast channel, and the technology using the beacon wireless communication method supports multiple vehicle terminals and multiple accesses. Therefore, when two or more terminals simultaneously access a wireless channel in a cell, a link setup is not performed.

In addition, the technology using the conventional cellular wireless communication method increases the service cost because the user must keep the call state to receive information, and the technology using the IMT-2000 wireless communication method has a frequency bandwidth according to the service provided There is a problem that the frequency should be changed according to the service desired by the user.

In order to improve the above problems, an intelligent transport system (ITS) has been proposed, and it can be classified into public transportation system, traffic management system, cargo transportation system, traffic information system, vehicle and road system according to the application field. have.

The intelligent traffic system implements a dedicated system to provide various services through collecting and distributing traffic information in real time, and a DSRC system is proposed as an example.

The DSRC system can accommodate various traffic services in one vehicle terminal, provide high speed packet communication by providing a stable data channel, communication in a narrow communication area and efficient use of radio resources, and voice synthesis. It provides a simple user interface for short text / image display, keypad input devices, and IC cards.

For example, the vehicle safety information using the DSRC system, if the information related to the traffic flow is provided to the driver can ensure the driver's safety.

However, the current DSRC system has a disadvantage in that service information is limited because it provides only specific information using a dedicated network.

Accordingly, an object of the present invention is to provide an Internet information service apparatus using a short-range wireless dedicated communication network created to service information to a driver in connection with various information providers connected to the Internet network in order to alleviate the above disadvantages.

In order to achieve the above object, the present invention provides an information providing server for providing information connected to an Internet network, transmitting vehicle registration information and a driver's information request signal, and receiving and displaying information requested by a driver on a display device. A BIS terminal for communication, a DSRC base station installed in an arbitrary area for two-way wireless communication with the BIS terminal, and collecting and analyzing transmission information from the DSRC base station, and requesting information from the information providing server when specific Internet information is required. It is characterized in that it comprises a DSRC server for searching and providing to the BIS terminal through the DSRC base station, and a router for connecting the DSRC server to the information providing server through the Internet network.

The DSRC server is configured to receive information from the information providing server using the TCP / IP protocol, convert the received information into a data form that can be recognized by the BIS terminal using the DSRC protocol, and then provide the information to the DSRC base station. It is characterized by.

The BIS terminal has a web browser function for retrieving a web page from an information providing server.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram of an information providing apparatus for an embodiment of the present invention, as shown in FIG. 1, an information providing server 300 for providing information by being connected to an Internet network, and vehicle-related information and a driver mounted on a vehicle. BIS terminal 100 for transmitting the Internet service information of the user and receiving the Internet service information requested by the driver and displaying it on a display device (not shown), and is installed in an arbitrary area and bidirectionally wirelessly connected with the BIS terminal 100. The information providing server 300 collects and analyzes the DSRC base station 211/212 for communication and the transmission information from the DSRC base station 211/212 through the DSRC-dedicated network 220, and requests the Internet service information.
