Description
[technical field]
The present invention is a kind of technology about guider, but particularly a kind of automatically selecting map block combination, and share the guider and the method for routing information.
[background technology]
Present guider is normally obtained all navigation maps through storage devices such as discs, maybe all navigation maps are stored in the guider, when guider navigates, again all navigation maps are read, and the cartographic information of show navigator map is on display screen.But the user usually only can use the navigation map of small part in a schedule time, so that guider expends many resources in unnecessary work, and increases many time for reading, consumes considerable memory headroom simultaneously.
On the other hand, guider is after finishing navigation, the user also can't be sent to the routing information of liking on the webserver, give other user to share the routing information of liking, perhaps download other the routing information that the user recommended, as guidance path or navigation sight spot etc. from the webserver.To this, but how to provide the guider and the method for the combination of a kind of automatically selecting map block, allow the user select the combination of map block voluntarily, and the routing information that will like is shared with other user, become the problem that the user is concerned about very much.
See also Fig. 1, it is the synoptic diagram of existing navigation map read method.Among the figure, navigation map 11 is stored in discs or all is stored in the guider.If the user is positioned at Shanghai, when guider began to navigate, guider can constantly read the total data of navigation map 11 and cartographic information 111 from discs or internal memory, no matter be Shanghai, Jiangsu, Zhejiang or other each area.Thus, user Shanghai of perhaps only can passing through, but other each area is read in the lump, not only wastes many time for reading, also can take many memory headrooms, and significantly reduce the execution efficient of guider.
Comprehensively above-mentioned, the shortcoming of prior art is that guider can read the total data of navigation map, the resource of losing time very much, and a large amount of committed memory space.And the user also can't select map block voluntarily, also can't share routing information with other user.
For solving the aforesaid drawbacks, to satisfy the demand of user to guider, the inventor through research and design and special topic discussion in many ways, but proposes guider and method thereof that a kind of automatically selecting map block make up in the present invention based on going in for the study for many years and many practical experience.
[summary of the invention]
In view of this, but the object of the present invention is to provide a kind of guider and method thereof of automatically selecting map block combination, particularly guider is connected to map data base, and in guider and map data base separate storage electronic chart and cartographic information, allow the free map block of wanting of user navigate, and share routing information with other user, to satisfy the demand of user to guider, solve the shortcoming of prior art simultaneously, except that the memory headroom that can reduce guider, also can accelerate the execution speed of guider, more can read suitable area information automatically, can also share routing information with other user.
For reaching above-mentioned purpose, but the present invention proposes a kind of guider of automatically selecting map block combination, and it connects a map data base, and map data base stores at least one cartographic information, cartographic information has the several region domain information, and each area information has plurality of sub-regions information.This guider comprises a storage module and a navigation module.Storage module stores at least one electronic chart, and electronic chart has several map blocks, and electronic chart is corresponding with cartographic information, and these map blocks are corresponding with above-mentioned zone information one by one.And navigation module connects storage module.When choosing these map blocks wherein one of at least the time on electronic chart, navigation module is the corresponding area information of selected map block, reads to storage module and stored from map data base.And when navigation module navigated, navigation module showed that the stored area information neutron area information of storage module wherein one of at least.
Secondly, the present invention also proposes a kind of method of automatically selecting map block combination, and it comprises the following step:
(1) guider is connected with a map data base, and map data base stores at least one cartographic information, cartographic information has the several region domain information, and each area information has plurality of sub-regions information;
(2) storage module with guider stores at least one electronic chart, and electronic chart has several map blocks, and electronic chart is corresponding with cartographic information, and these map blocks are corresponding with above-mentioned zone information one by one;
