Traffic information generation / provision system using internet and method of generation / provision thereof {CREATI0N / PROFFER APPARATUS OF TRAFFIC INFORMATION USE INTERNET AND THE METHOD CREATI0N / PROFFER METHOD THEREOF}

The present invention relates to a system for generating / providing traffic information using the Internet and a method of generating / providing the same, and in particular, by using a communication network of a mobile telephone already equipped with location information of a vehicle transmitted from a mobile telephone carried by anyone. The present invention relates to a system for generating / providing traffic information using the internet and generating / providing the same by generating traffic information through the internet.

As a conventional example of this kind, there is a traffic information providing apparatus using a mobile communication network disclosed in Korean Patent Registration No. 0169045 (Registration Date; October 8, 1998).

The traffic information providing apparatus using the mobile communication network disclosed in the Korean Patent Publication is installed in the vehicle 100 as shown in FIGS. 1 and 2, and has its own ID code and trajectory from the NAVSTR GPS satellite 10. A first GPS receiver 11 for receiving position and time information and calculating position data, and the first GPS receiver 11 receives an ID code, an orbit position, and time information of the NAVSTR GPS satellite 10, and receives the first GPS receiver 11. 1 A mobile communication device for calculating a current position of the vehicle based on information input from the GPS receiver 11 and time information input from a reference time pulse generator, and transmitting the position data using the public communication network 200. (12), a vehicle monitor (13) for receiving and displaying traffic information from the mobile communication device (12), and receiving information from the mobile communication device (12) and outputting the plurality of control centers (300). Public network (20 0), a public communication network connection unit 14 installed at a control center 300 remote from the vehicle and connected to the public communication network, and a public communication network connection unit 14 installed at the control center 300. The ID code of the NAVSTR GPS satellite transmitted by the mobile communication device 12, orbital position, and time information are processed to calculate the current position and longitude of the vehicle, and the traffic information is generated from the calculated data. A central processing unit 15 for transmitting to the mobile communication device 12 of the vehicle and a monitor 16 for receiving and displaying current position and hardness data of the vehicle 100 from the central processing unit 15. And a second GSP receiver 17 which is installed in the control center 300 and receives the satellite's own ID code, orbit position and time information from the NAVSTR GPS satellite 10 and calculates position data.

In the traffic information providing apparatus using the conventional mobile communication network configured as described above, since 24 NAVSTR GPS satellites are orbiting about 20,000 km orbit at a cycle of 12 hours, the NAVSTR GPS satellites 10 have their own ID codes. When the orbit position and time information are transmitted, the first GPS receiver 11 installed in the vehicle 100 receives information emitted from the satellite 10 and outputs the information to the mobile communication device 12, and the mobile communication device 12. ) Measures the delay time of the radio wave from the information obtained from the first GPS receiver 11 and obtains the current position from the distance from the orbit of the GPS satellite 10.

In other words, the reference time pulse generator circuit 121 of the mobile communication device 12 installed in the vehicle 100 is provided with a crystal oscillator (not shown) and is a world standard time based on information output from the GPS receiver 11. Generates a clock pulse synchronized with the clock signal. The clock pulse is input to the main controller 122, and the delay time is increased by the difference between the time received by the first GPS receiver 11 and the time transmitted by the GPS satellite 10. The measured and measured delay time considers the trajectory of the GSP satellite 10, and the main controller 122 calculates the current position of the first GPS receiver 11. The calculated position information of the vehicle 100 (that is, position information of the GSP receiver 11) is transmitted to the public communication network 200 through the transceiver 123.

Traffic information such as the location information of the vehicle through the public communication network 200 is transmitted to a plurality of control center 300, the control center 300 receives the location information of the vehicle by the public communication network connection 14 The received position information of the vehicle is input to the central processing unit 15 and compared with the position information of the control center 300 to calculate the absolute position and the relative position of the vehicle, and then processed by the traffic information processing algorithm as traffic information. It is generated and transmitted through the public network connection 14 to the mobile communication device 12 of each vehicle. The location information of the control center 300 is output by the second GPS receiver 17 receives the location information from the GSP satellite 10 to the public communication network connection unit 14.

Such a location information calculation process is performed periodically or irregularly and processed by an algorithm for calculating traffic information, and used to determine the degree of congestion. It is transmitted to the mobile communication device 12 of 100 and displayed on the vehicle monitor 13 installed in the vehicle 100 and provided to the driver.

However, although the traffic information providing apparatus using the conventional mobile communication network configured as described above is not shown, since a separate wireless modem is used and the first and second GPS receivers 11 are used, the vehicle terminal is expensive. In addition to this, there is a problem in that signals received from a traffic information providing apparatus using a mobile communication network installed in a vehicle are received by the NAVSTR GPS satellite 10, and these signals are processed to read the speed of the vehicle. There are various problems that it is impossible to read the driving speed of the vehicle unless the vehicle is equipped with a traffic information providing apparatus using a mobile communication network.
