(2) B → A is promptly with the A that updates the equipment of the corresponding data in the equipment B.
(3) Merge, promptly device A, B two device intercommunicatings have or not.
(4) other.
Get in touch through synchronization module 3 between the equipment, and absorb or the reconstruct local datas through map datum engine modules 2 separately.
Synchronization module wherein is divided into two parts,
(1) be responsible for the communication of equipment room, the communication function unit 31 (Communication Function Unit) of data transmission, the transmission of synchronous foundation of equipment room and data is responsible in the communication function unit, comprises wire communication, radio communication or the like mode;
(2) be responsible for the execution functional unit 32 (Execute Function Unit) that command analysis is carried out; Carry out functional unit 32 and be responsible for the parsing of order; And notice map datum engine modules 2 (Map Data Engine) do corresponding action; As: picked-up data and packing, perhaps the data that receive are put into map data base 1 (Map Database).Carry out the timestamp that functional unit 32 can produce map information updates (, then need not upgrade) if compare when comparatively identical when two equipment timestamps, and the identification marking ID of update content.
Indicate required data updated among one of the identification marking ID and be any one or multiple combination in road (ROAD), terrestrial reference (POI), river (RIVER), railway (RAILWAY), zone (AREA) or the like, and some concrete lastest imformations.Carry out functional unit 32 and differentiate the user successively and want the particular content that upgrades, and invocation map data engine module 2 is searched or typing in map data base 1.The concrete form of ID can be defined according to concrete application by the user voluntarily, below form be a kind of concrete instance of the present invention:
| Country code | City codes | The administrative area code | Data type | Details | Other |
Wherein, indicate required data updated type in one of the data type, comprise such as
1) road (ROAD)
2) terrestrial reference (POI)
3) river (RIVER)
4) railway (RAILWAY)
5) zone (AREA)
In any one or multiple combination.
For map data base 1 (Map Database), see also shown in Figure 6ly, wherein, map data base 1 is divided into spatial data and data of description, and spatial data comprises the geospatial location information of data; Data of description comprises the humane information of data, such as: country, classification, city, postcode, keyword title or the like.
(1) map space data
Map data base spatial data search efficiency depends on whether good space index structure is arranged, and this kind index structure must be managed multidimensional and the spatial data of volume is arranged, and removes to read the spatial data in the specified scope with minimum disk access and minimum access speed.
The present invention can adopt the R_tree dynamic index structure that is proposed by Guttman in 1984, and it is a kind of height balanced tree similar in appearance to B_tree, can search, insert spatial data and operation such as deletion.
Use the advantage of R_tree space index structure:
Can accurately grasp the spatial data in the required scope via R_tree spatial database index structure, not have the problem of the unnecessary extracting of data.
Only deposit the R_tree index structure in the memory body, solid data then leaves in the disk, and the spatial object data just can be read in to memory body, as save the use amount of memory body this moment when needed.
Because solid data is stored in the disk, so limit than the no datat storage volume.
Grasp desired data in index value to the disk according to the R_tree record, do not have unnecessary disk operating.
In order to increase the search speed of data object, when real doing, can add a B_tree index file, be used for writing down the position of each object in archives.
So the spatial data index structure is made up of R_tree index structure, B_tree index file and spatial object data file three parts.
(2) map data of description
As far as Database Systems, a good search index structure can also can make things convenient for the user to find required data fast so that System Operation is more efficient.
With the terrestrial reference search index is example; According to the electronic map data that GIS map manufacturer is provided, every landmark data contains fields such as terrestrial reference title, terrestrial reference numbering, terrestrial reference kind, terrestrial reference belonging country, the affiliated city of terrestrial reference, the affiliated postcode of terrestrial reference, terrestrial reference coordinate.Be to improve the terrestrial reference search efficiency, the user can self manufacture terrestrial reference search index file, and form is from ordering, and sees also shown in Figure 7ly, and objID wherein is B among Fig. 6
+ObjID in the _ tree index file.
For map datum engine modules 2 (Map Data Engine); Because map datum engine modules 2 is the difference of data layout according to the map; And the company, purposes of exploitation are different; Different on the implementation method of details, but its function all can realize the reconstruct of searching, absorbing of map datum or local data.
Usually on the terminal, there is special interface to realize these functions, such as, choose the country that needs inquiry, city, administrative area etc. by the user, and the classification of searching, such as, related datas such as road, terrestrial reference, restaurant.After the user imported corresponding scope, the map datum engine can be accomplished and search, insertion, the reconstruct work of extraction and data.
Suppose that step is following with the Shanghai City landmark data of the terminal A Shanghai City landmark data of new terminal B (only be designated as example with ground here, other categorical data is in like manner) more:
(1) searches and extracts the Shanghai City landmark data at the A end.
When the extraction work of carrying out data, the form of packing data all can be ordered certainly, as long as A, B terminal can both identifications, shown in following table:
(2) in the insertion of B end, reconstruct Shanghai City landmark data.
The B end is received the data sent bag, and identification needs the type of renewal, parses every data then, inserts data file, upgrades index.
Adopted the device and method of the synchronism update of map data on the above-mentioned handhold GPS terminal device; Owing in terminal device, added synchronization module 3; And be connected with map data base 1 through map datum engine modules 2; Thereby can be under user's order, the real-time demand with the user is sent on the opposite equip. through the mode of ordering, and extracts processing or data insertion reconstruction processing through carrying out corresponding data search after the opposite equip. resolve command; Not only can only upgrade the part that needs renewal according to user's requirement; And reduced system overhead, improved the efficient of exchanges data, and the data that can protect the User Defined data message can not be updated automatically as required cover; Moreover, apparatus and method of the present invention use flexible, and usable range is comparatively extensive, bring great convenience for people's life, and make the GPS technology to be accepted and application by more people.
In this instructions, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
