At mobile terminal, show and the system and method for sharing real-time mapTechnical field
The present invention relates to a kind ofly at mobile terminal, show and the system and method for sharing real-time map, special, relate to a kind of mobile terminal that is embedded in, mutually share the system and method for real-time geographic positional information.
Background technology
Modern society, is that daily life or business negotiation all be unable to do without mobile phone, and mobile phone has become requisite instrument in people's life.Along with scientific and technical development, various smart mobile phones are favored by people gradually.In the various information service that can provide at smart mobile phone, GIS-Geographic Information System has incorporated the main flow of information technology, and becomes the important component part of mobile Internet development.GIS-Geographic Information System also differentiates positioning service (LBS), and LBS is used GPS with mobile device, to show its position by the relation of location and fixed base stations, mobile device or return their position to an one central server demonstration or do other processing.Along with GPS function and the mobile terminal (mobile phone, Pad, notebook computer) of becoming stronger day by day are integrated, these services continue development, geographical position and association attributes organically will be combined, according to user need to by cartographic information, both pictures and texts are excellent presents to user, provide that people go on a journey just.
But existing engine map or map display program based on mobile terminal (mobile phone, Pad, notebook computer) is often all very complicated, also relatively high to the requirement of mobile phone hardware, sharing of real-time geographic positional information between good friend is directly perceived not and effective, particularly for mobile terminal or unintelligent terminal that map program is not installed, cannot show positioning map, also cannot completing place information share or obtain other people sharing, brings great inconvenience to user.
Summary of the invention
The present invention overcomes above-mentioned defect, provides a kind of and has shown real-time map and the system and method for sharing map at mobile terminal, can realize sharing of real-time geographic positional information between a plurality of users.
Of the present inventionly at mobile terminal, show that real-time map is such with the system of sharing map: it comprises that service terminal and at least one mobile intelligent terminal and service terminal and mobile intelligent terminal are by the network interconnection, wherein service terminal comprise transceiver module, module, cutting module, mobile intelligent terminal comprises GPS locating module, Control module for map, map display module, transceiver module;
Wherein transceiver module is used for receiving transmission information;
Ground module being written into and storing for map, receives the GPS map locating information from intelligent terminal, and processes;
Cutting module is used for cutting the map vector of unit are size;
Longitude and latitude and elevation information that Control module for map is used for GPS to navigate to send to service terminal, and map vector is downloaded in request;
Map display module is used for the map downloading to and relevant information to be shown to user by display.
Of the present invention is such in mobile terminal demonstration with the system of sharing real-time map: it comprises the following steps:
Single mobile intelligent terminal real-time map shows:
A:A user select to show real-time map information at mobile intelligent terminal, opens GPS locating module simultaneously, and Control module for map will obtain longitude and latitude and the elevation information that GPS navigates to and send to service terminal, and map vector is downloaded in request simultaneously;
B: service terminal is received after the information of steps A, the longitude and latitude that the GPS of take navigates to and be highly the centre coordinate of map, according to the size of the size of mobile intelligent terminal display screen and map scale, cutting module will dynamically cut out the map vector of corresponding size from map, and sends to mobile intelligent terminal;
C: mobile intelligent terminal receives map vector, and Control module for map sends map vector to map display module, and map display module shows map vector on display screen;
D: Control module for map obtains GPS locating information more again at interval of setting-up time, then repeating step A ~ C;
E: when party A-subscriber mobile intelligent terminal display screen do mobile, while zooming in or out the operation of map, Control module for map resends service terminal by the center of map and engineer's scale size information, again obtains map vector.
Sharing real-time map shows
A:A user selects to share contact person, and will share associated person information and be sent to service terminal;
B: service terminal will re-send to the map vector of issuing party A-subscriber on the mobile intelligent terminal of sharing contact person;
C: service terminal receives the geographical location information of sharing contact person simultaneously, according to relative position, calculating map scale size, all shared people's real-time geographic position and corresponding map vector are presented on everyone mobile intelligent terminal in real time, and the up-to-date geographical location information of Real-time Obtaining, and upgrade in Fixed Time Interval.
Optimally, while sharing real-time map, the mode that sends the map vector of real-time geographic position and correspondence is set to instant message, note or URL form and shares.
Optimally, sharing of Geography of enterprise positional information is URL and connected on the word of the address of enterprise electronic calling card, by mailbox, shares to mobile client terminal with website.
By note, share real-time map
A:A intelligent terminal user selects unintelligent terminal user as shared contact person, and this shared associated person information is sent to service terminal;
B: service terminal generates URL according to party A-subscriber's longitude and latitude and elevation information and is connected, and URL is connected with note form and sends to and share contact person;
C: share contact person and open in short message after URL connection, call browser program, show the party A-subscriber's who downloads by service terminal map vector with web or wap mode;
D: service terminal receives the geographical location information of sharing contact person simultaneously, according to relative position, calculating map scale size, all shared people's real-time geographic position and corresponding map vector are presented on everyone client terminal in real time, and the up-to-date geographical location information of Real-time Obtaining, and upgrade in Fixed Time Interval.
Of the present inventionly at mobile terminal, show with the system and method for sharing real-time map and show in real time the map vector of position on the mobile intelligent terminal client, and can share this map vector with shared people in real time, and be not subject to the impact of mobile phone model and function, as long as there is GPS function.
Accompanying drawing explanation
Fig. 1 is that the present invention shows and the block diagram of sharing the system of real-time map at mobile terminal.
