Abstract
The invention provides a method for installing a TMC receiving apparatus to receive TMC data at a server terminal and transmitting the data to a guidance terminal through a wireless communication network. The method comprises the following steps: the real-time TMC data are to be obtained by the guidance terminal without independent installation of the TMC receiving apparatus; the guidance terminal can be wirelessly connected with the server provided with the TMC receiving apparatus; and the TMC data are obtained by the server through the TMC receiving apparatus and the TMC data are transmitted to the guidance terminal through wireless connection.
Description
The present invention relates to technical fields such as TMC technology and radio communication, particularly a kind of navigation terminal utilizes wireless network to obtain the method for TMC data by the server with TMC receiving equipment.
Background technology
TMC (report of Traffic Message Channel transport information) function is an information service in the FM frequency modulation Radio Resource system, is used to broadcast instant traffic and meteorological information.By the TMC receiving equipment is installed, navigation terminal can receive traffic information in real time, avoids the traffic congestion route, plans travel route more efficiently, improves the service efficiency of road and vehicle.
On the traditional approach, generally be to set up a radio station at the traffic control center in a city, the FM signal of emission transport information situation, i.e. TMC data; Newly-increased TMC receiving equipment can be separated the information that frequency modulation obtains traffic, and then traffic information is presented on the map of navigator on car navigation device.From with last, adopt traditional approach, need all navigation terminals to increase the TMC receiving equipment and receive the TMC data, this has not only increased the complexity of equipment, and causes the rising of navigation terminal cost.If obtain real-time traffic information but only a TMC receiving equipment is installed at server end, and then the TMC data are connected by wireless network deliver to navigation terminal, so just can save the cost of extensive interpolation equipment for each terminal equipment adds the TMC receiving equipment separately.
Summary of the invention
The object of the present invention is to provide and a kind ofly at server end the TMC receiving equipment is installed and is received the TMC data by disposable, navigation terminal is set up by wireless network and is connected to server end, obtain the new method of TMC data, this method has realized that numerous navigation terminals can not need to acquire the function that independent TMC receiving equipment can obtain TMC information, has solved numerous navigation terminals and need buy the problem that the TMC receiving equipment is installed for obtaining the TMC data.
For this reason, the invention provides following solution:
A, server end are installed the TMC receiving equipment, receive TMC data such as real-time traffic information and weather information.
B, navigation terminal and server end are set up wireless connections by wireless network.
C, server end connect the TMC data that receive and send navigation terminal to or navigation terminal obtains the TMC data by wireless network from server end by wireless network.
D, navigation terminal are presented at information such as real-time road on the navigation terminal according to the TMC data that obtain from server end, check for the user.
Brief Description Of Drawings
Accompanying drawing 1 is existing TMC function implementation structure schematic diagram.
Accompanying drawing 2 is TMC function implementation structure schematic diagram among the present invention.
Embodiment
Specify the present invention below in conjunction with accompanying drawing.
See also accompanying drawing 2, accompanying drawing 2 is realized the structural representation of TMC function for design among the present invention.Comprise:
TMC signal emitting-source: be responsible for FM signal such as broadcast transmission real-time road condition information and weather forecast, i.e. the TMC data.
TMC receiving equipment: the functional module of being responsible for the TMC data of reception TMC signal emitting-source emission.
Server end:, can receive the TMC signal of TMC signal emitting-source emission by the TMC receiving equipment is installed; Can set up radio communication by wireless network and navigation terminal and be connected, the TMC data are sent to navigation terminal or obtain the TMC data automatically by navigation terminal.
Navigation terminal: can link to each other with server and obtain the TMC data by wireless network, and the TMC data are presented on the terminal equipment.
Accompanying drawing 1 is existing TMC function implementation structure schematic diagram.Existing navigation terminal desire realizes the TMC function, and the TMC receiving equipment need be installed separately, receives the TMC data of the frequency modulation of TMC signal emitting-source emission by the TMC receiving equipment.The process that realizes the TMC function with existing navigation terminal is different, and the navigation terminal desire realizes the TMC function among the present invention, does not need to install separately the TMC receiving equipment again.Specify the process that navigation terminal is realized the TMC function below in conjunction with accompanying drawing 2:
Step 1, server end is installed the TMC receiving equipment, by the TMC receiving equipment, receives the TMC data of TMC signal emitting-source emission.
Step 2, server end is set up wireless connections by wireless network and navigation terminal, and the TMC data are sent to each navigation terminal.
After step 3, navigation terminal receive the TMC data by Radio Link, analyze the TMC data and information such as real-time road identifys (for example the navigation electronic chart shows the congestion state of road etc.) on terminal, the confession user checks.
Claims (5)
1. by server end the TMC receiving equipment is installed and is received the TMC data for one kind, send data the method for navigation terminal to by wireless network again, it is characterized in that this method comprises following aspect:
A. at server end the TMC receiving equipment is installed, is received real-time road conditions broadcast message TMC data.
B. server links to each other with the navigation terminal equipment with radio communication function by wireless network, can send the TMC data to navigation terminal by wireless communication networks or navigation terminal obtains the TMC data by wireless network from server end.
C. navigation terminal receives the TMC data by wireless network, handles the back and mark out out of Memory such as real-time road condition information and weather forecast on electronic chart.
2. according to claim 1 by server end reception TMC data, again data are sent to the method for navigation terminal by wireless network, it is characterized in that in this method, server end is installed the TMC receiving equipment in order to receive the TMC data, and navigation terminal does not need to install separately the TMC receiving equipment again.
3. according to claim 1 by server end reception TMC data, again data are sent to the method for navigation terminal by wireless network, it is characterized in that in this method, navigation terminal receives the TMC data no longer by the TMC receiver module is installed, and is connected reception TMC data but set up radio communication by wireless network and server end.
4. according to claim 1 by server end reception TMC data, again data are sent to the method for navigation terminal by wireless network, it is characterized in that in this method, a plurality of navigation terminals can be shared a server end that the TMC receiving equipment is installed, and common reception comes the TMC data of server end since then.
5. according to claim 1 by server end reception TMC data, again data are sent to the method for navigation terminal by wireless network, it is characterized in that in this method that navigation terminal not only has location and navigation feature, also should have radio communication function.
