Network radio station system for real-time broadcasting traffic information based on user position

Abstract

The invention relates to a network broadcasting station system for broadcasting traffic information in real time based on user location, which comprises an information release server, a broadcast client, a listen-in client, a control center, a map server and a transmitting gateway; the network broadcasting station system established by the invention needs no person for speech broadcast and completes the network broadcasting station broadcast of real-time traffic information. The broadcasting station system can acquire road condition textual messages in a certain region produced by an intelligent traffic system in real time through the broadcast client; the road condition textual messages are converted to the speech for broadcasting in the broadcasting station. The listen-in client acquires a user geographical position in real time through GPS position technology; through relevant calculations, an accurate network broadcasting station is chosen for listening to the real-time traffic information. When the user geographical position is changed, the system can always select a network broadcasting station in a proper region to provide positive real-time traffic information services forusers. The network broadcasting station system can have large-scale terminal access through a strategy of multi-gateway transmission and p2p technology and is an integrated real-time traffic information network broadcasting station.

Description

technical field [0001] The invention relates to a network radio system for broadcasting traffic information in real time based on user positions, and belongs to the technical field of intelligent traffic. Background technique [0002] With the rapid growth of the urban population, the urban road traffic situation is becoming increasingly tense, and the traditional traffic command mode can no longer meet the needs. The intelligent transportation system (ITS) technology has emerged as the times require. It can improve road use efficiency, save energy, protect the environment, reduce traffic jams, It has played a huge role in increasing the speed of vehicles and reducing traffic accidents. However, in the traditional intelligent transportation system, after the traffic information is collected, processed, and analyzed, it mainly provides real-time traffic information services to the vehicle navigation system through media media such as FM radio or light markers. Publish real-t...

AI Technical Summary

Problems solved by technology

For users such as drivers who are driving, they will not be able to obtain real-time traffic information services in time

The defects of the traditional ITS publishing system lead to the underutilization of the real-time traffic data generated by it

[0003] On the other hand, although traditional radio stations can broadcast traffic information so that people can obtain traffic information through sound in time, there are shortcomings such as low efficiency, high cost, very small coverage, manual broadcasting, and lack of pertinence and interaction. The frequency band it occupies is a poor resource, and traditional radio stations are far from meeting the needs of users when broadcasting traffic information

[0004] The scarcity of traditional radio frequency band resources, the rapid development and popularization of the Internet, and the development of streaming media technology provide a strong living space for the emergence and development of Internet radio stations, but there is no Internet station that provides real-time traffic information. The cost of collecting traffic information is too high
