Abstract
The invention relates to a navigation system and a weather forecast information acquisition method thereof. The method comprises the following steps of receiving an instruction given by a user to acquire a weather forecast, judging whether the navigation system is in a browsing mode at present and requesting the weather forecast information of an administrative region where a browsing pointer is from a server if the navigation system is in the browsing mode or requesting the weather forecast information of an administrative region where a user vehicle is from the server otherwise. Due to the technical proposal of the invention, the navigation system is high in positioning precision and not easy to have the problems of mistake and missing the information of the administrative regions, thereby ensuring that the user can obtain the correct response information of weather forecasts according to own need. In addition, the technical proposal also can be applied to the moving-running state of the user vehicle.
Description
Technical field
The invention belongs to field of navigation technology, relate in particular to a kind of navigational system and weather forecast information acquisition method thereof.
Background technology
At present, (Global Positioning System GPS) is one of GPS navigation important application direction to automobile-used GPS.The gps antenna of automobile-used GPS navigation system receives from 3 data messages that transmitted in earth-circling 24 gps satellites at least, in conjunction with the electronic chart that is stored in the Vehicular navigation terminal, the position coordinates of determining by gps satellite signal is complementary therewith, determines the accurate position of navigation object in electronic chart.The user of steering vehicle can transfer to computer and select driving path when driving, and as direction guiding, thereby correctly arrive the destination apace.
Fig. 1 is the structural drawing of Vehicular guidance system in the prior art, and this Vehicular guidance system is made up of loudspeaker 1, chuck assembly 2, input media 3, voice output 4, display device 5, control device 6, GPS receiving trap 7 etc.
Chuck assembly 2 can be reduced into numerical data to the recorded content that inserts in the recording medium that records map datum, control program data etc. wherein, and delivers to and deliver to control device 6.
Input media 3 is made of button, rocking bar, knob, touch-screen etc.Input media 3 is used to import user's various requirement.Input media 3 is delivered to user's input signal in the control device 6.
The voice data translation that voice output 4 is sent control device 6 here is a voice signal, delivers to loudspeaker 1.The voice signal that loudspeaker 1 is sent voice output 4 here converts sound and output to, and like this, loudspeaker 1 just can cooperate the needs of control device 6, sends the voice of various operational notifications and route guidance.
7 receptions of GPS receiving trap detect the present position and the moving direction of vehicle from the signal of gps satellite, and convert detected result to protocol data, and these protocol datas further are sent to control device 6.
In the prior art, mainly contain following two kinds for the method for obtaining Weather information:
One, can ask weather forecast information by intelligent mobile phone terminal to the service provider by wireless telephony network communications protocol (for example GPRS).Its course of work is as follows:
A, smart mobile phone send the weather forecast information request by network to server;
Server obtains the IP address of smart mobile phone client;
B, server obtain the administrative region at smart mobile phone user place according to the IP address of smart mobile phone client;
C, server lookup are arrived this regional information, and are returned to client;
D, client show the area information that receives.
Above this weather forecast technical scheme because the IP address of service provider may be incomplete with the corresponding storehouse of administrative region, and exists the wrong plain problem of information.
Two, smart mobile phone can also be by short message receiving-transmitting to service provider's service number request weather forecast information, and its course of work is as follows:
A, cell-phone customer terminal send the weather forecast information request to service provider's service number, comprise administrative information region in the solicited message;
The weather forecast information of the administrative region that b, whois lookup cell-phone customer terminal are sent;
C, server send weather forecast information to cell-phone customer terminal;
D, client show the area information that receives.
Above this weather forecast technical scheme, if the administrative information region mistakes and omissions that client is given, the wrong plain weather forecast response message of also will navigating.In addition, drive to be displaced in the middle of the administrative region if the client is in, so, the user has to repeatedly when sending weather report request, also needs simultaneously constantly revise the administrative region simultaneously, and navigation user is painstaking, and operating efficiency is extremely low.
Summary of the invention
