Abstract
The invention discloses a real-time vehicle navigation method based on a wireless data network. In the method, (1) destination information is input into a vehicle-mounted end by a user, positioning information is acquired by a GPS (Global Position System) positioning module and sent to the vehicle-mounted end, and the positioning information, the destination information and a vehicle identification code are sent to a server end through the wireless network by the vehicle-mounted end; (2) the sever end receives the information sent by the vehicle-mounted end, respectively extracts the positioning information, the destination information and the identification code information, works out a navigation path according to GIS (Geographic Information System) data, a digital map and traffic condition information, and marks a vehicle position on the path in real time and finally stores the vehicle position into a database at the server end; and (3) the positioning information, the map and the path information of the vehicle can be checked from a screen at the vehicle-mounted end through web access or use of special software by the vehicle-mounted end and automatic identification by the server end, thereby the real-time navigation of the vehicle can be realized. The invention can acquire real-time traffic conditions, can update GIS and a digital map at real time, thereby realizing real-time navigation and improving vehicle running efficiency.
Description
Technical field
The invention belongs to areas of information technology, relate to vehicle mounted guidance, especially based on the automobile navigation method of radio data network.
Background technology
In the last few years, the technical development of vehicle mounted guidance is very fast, obtaining of relevant traffic information is also very convenient, but general in-vehicle navigation apparatus all is based on and uses under the off-line state, be about to electronic chart and be installed to car-mounted terminal in advance, then by receive GPS information with the location mark of vehicle on map, by the input destination-address, terminal is sought a paths automatically on map, the shortcoming of this series products mainly contains two aspects, at first be to need often to upgrade map, the map renewal frequency of general this series products in half a year even annually, because urban development is maked rapid progress, this renewal speed has not caught up with the step that urban road construction changes, and adopts out-of-date map can cause the accuracy of navigating and seriously influences; Next is that real-time road can not obtain, because what adopt is that the best guidance path of its planning of navigation under the off-line state is not consider real-time traffic according to the physical pathway on the map, therefore in the time of the urban transportation peak, the traffic route that navigational system is cooked up minimum circuit not necessarily consuming time, use this system may additionally increase the oil consumption and the time cost of trip peak period, the requirement in the energy-saving city of construction that this and current social are advocated is not inconsistent.
Method of the present invention has solved above two shortcomings (be map obtain with traffic obtain) effectively, and has showed three kinds characteristics: 1, can obtain free GIS, digital map information; 2, can realize GIS, digital map information real-time update; 3, can obtain real-time traffic information.
Summary of the invention
The object of the present invention is to provide a kind of real-time vehicle navigation method, utilize the method for radio data network and server exchange data to realize the vehicle real time navigation function, make vehicle-mounted end can obtain the real-time navigation service based on radio data network.
For reaching above purpose, solution of the present invention is:
A kind of method of real-time vehicle navigation, the user is to vehicle-mounted end input destination information, and vehicle-mounted termination is received GPS module locating information, with destination information, preallocated vehicle identification code, by wireless network, is sent to server end after treatment.
Server end receives the data that vehicle-mounted end sends, extract location, destination, information of identification code respectively, according to GIS information (server is taken from numerical map by network in real time), numerical map (server end is taken from numerical map supplier by network in real time), traffic information (server is taken from traffic information center by network in real time), the guidance path with planning deposits the service end database in after treatment.
Vehicle-mounted end through web visit or use special software, through the server end automated validation, just can view this vehicle location information by radio data network on vehicle-mounted end screen, map, routing information can carry out this car navigation work.
Owing to adopted such scheme, the present invention has following characteristics: this method is based on radio data network, utilize web visit or special software to obtain the real-time navigation service, solved the numerical map charging problem effectively, real-time traffic, GIS information are obtained problem.
Embodiment
The present invention is further illustrated by the following examples.
When the needs navigation Service, start vehicle-mounted end, the user import destination information, by the GPS locating module obtain locating information and with preallocated vehicle identification code by wireless communication module and the Internet, send to server end.
After server end receives the information of vehicle-mounted end transmission, extract information such as location, destination, identification code respectively, calculate guidance path according to GIS data (server end is taken from numerical map by network in real time), numerical map (server end is taken from numerical map supplier by network in real time), traffic information (server end is taken from traffic information center by network in real time), and vehicle location is marked on the path in real time, deposit the service end database at last in.
Vehicle-mounted end open any browser or special software can be checked the current every information of this vehicle by radio data network Connection Service device behind the server end automated validation, comprise location, road conditions and guidance path.
The present invention has utilized radio data network, has accomplished the real-time update of GIS, numerical map, traffic, has solved GIS, the copyright charging problem of numerical map, traffic effectively and has obtained problem, the replacement problem of GIS, numerical map and traffic.Because core data is handled to merge and all finished at server end, therefore the work of treatment of vehicle-mounted end has seldom reduced vehicle-mounted hardware cost.Because the development of wireless communication networks (3G, 4G), the significantly lifting that the speed of wireless data transmission and stability obtain, therefore navigation real-time of the present invention can be continued to optimize and becomes and become better and better along with telecom operators' wireless network.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
