Abstract
The invention discloses a distributed type map display method and device and a splicing wall system. All display client sides share the same hot spot data, and the hot spot data are stored in a specific data container. When a hot spot is added, all client sides obtain hot spot data which correspond to the hot spot from the data container and display the hot spot data in a rendering mode. Therefore, the memory usage of the client sides is reduced, the load of network transmission is relieved, and the display performance of the whole system is improved notably especially when the size of the hot spot data is large.
Description
Technical field
The present invention relates to Map Display Technology field, the distributed display methods of more particularly to a kind of map, device and spelling
Connect wall system.
Background technology
It is that map is divided that distributed maps show, and shows a part of map respectively using multiple display clients
Mode.The formation combination as shown in figure 1, the display screen of all display clients is stitched together, thus complete show map.
Traditional technology, the base map of each display client show map first, when needing to add focus on base map,
Server is controlled to send a hot spot data respectively to each display client, described hot spot data is deposited into by display client
Self EMS memory chained list, and calculate residing scope on map according to residing column locations, cut from the hot spot data being stored
Take the focus in respective range and render display.
In such scheme, each display client has itself and shows all of hot spot data of client with other,
Quick display can be realized according to own range when base map translation or when scaling, but can be to single when hot spot data to be shown is excessive
Individual display client causes serious performance burden, causes display performance to decline.
Content of the invention
Based on above-mentioned situation, the present invention proposes a kind of distributed display methods of map, device and joined screen system, to add
The fast speed showing client show map.
A kind of joined screen system, including control server and multiple display client,
Also include data, services end,
Described control server sends hot spot data bag to described data, services end, and sends out to display client each described
Send interpolation focus order；
Described data, services end receives and parses through described hot spot data bag；
After described display client terminates to described interpolation focus order, obtain corresponding focus number from described data, services end
According to and carry out rendering display, corresponding hot spot data and the column locations phase residing on combination of described display client
Adapt to.
A kind of distributed display methods of map, including step：
Receive and add focus order；
Obtain hot spot data；
According to the ranks distribution of display client, described hot spot data is divided；
Hot spot data after dividing is distributed to corresponding display client carry out rendering display.
A kind of distributed display device of map, including：
Order receiver module, adds focus order for receiving；
Data acquisition module, for obtaining hot spot data；
Data division module, divides to described hot spot data for the ranks distribution according to display client；
Distribution display module, for by the hot spot data after dividing distribute to corresponding display client carry out rendering aobvious
Show.
A kind of joined screen system, including the distributed display device of above-mentioned map.
The distributed display methods of map of the present invention, device and joined screen system, all display clients share portion focus
Data, and when adding focus, hot spot data is divided, the focus in respective range is distributed for each display client,
Each display client carries out rendering display to corresponding focus respectively.So, decrease the EMS memory occupation of display client, subtract
The light load of network transmission, when particularly hot spot data amount is larger, can significantly improve the display performance of whole system.
Brief description
Fig. 1 is traditional joined screen system；

Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is described in further detail.It should be appreciated that specific embodiment described herein is only in order to explain this
Bright, do not limit protection scope of the present invention.
The distributed display methods of map of the present invention, as shown in Fig. 2 include step：
Focus order is added in step S101, reception；
Step S102, acquisition hot spot data；
Step S103, according to display client ranks distribution described hot spot data is divided；
Step S104, the hot spot data after dividing is distributed to corresponding display client and carry out rendering display.
This method is directed to display client and has shown base map, needs to increase the situation of focus on base map.In order to reduce heat
The occupancy to display client's end memory for the point data, this method leaves the hot spot data of acquisition in specific data, services end, should
Data, services end can be the device that hard disk, database, internal memory container etc. have store function.Ranks according to display client
Hot spot data is divided into corresponding number by distribution, and every portion is distributed to corresponding display client, and display client will
Corresponding hot spot data interpolation is shown on corresponding base map, completes focus and adds task.
As a preferred embodiment, described hot spot data is the hot spot data in GIS map.
The distributed display device of map of the present invention, as shown in figure 3, include：
Order receiver module, adds focus order for receiving；
Data acquisition module, for obtaining focus number after described Order receiver module receives described interpolation focus order
According to；
Data division module, described in obtaining to described data acquisition module according to the ranks distribution of display client
Hot spot data is divided；
Distribution display module, for by the hot spot data after dividing distribute to corresponding display client carry out rendering aobvious
Show.
As a preferred embodiment, described hot spot data is the hot spot data in GIS map.
As a preferred embodiment, the described hot spot data obtaining is stored in data clothes by described data acquisition module
Business end.
By distributed for above-mentioned map display device applications in traditional joined screen system, that is, form the combination system of the present invention
System.
Joined screen system of the present invention, including controlling server and multiple display client, as shown in figure 4, also include data
Service end.
Described control server sends hot spot data bag to described data, services end, and sends out to display client each described
Send interpolation focus order；Described data, services end receives and parses through described hot spot data bag；Described display client terminates to described
After adding focus order, obtain corresponding hot spot data from described data, services end and carry out rendering display, corresponding heat
Point data is adapted with described display client location on combination.
As a preferred embodiment, described data, services end is database or internal memory container.
