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 technique field, particularly relate to the distributed display packing of a kind of map, device and combination system.
Background technology
It is that map is divided that distributed map shows, and adopts a plurality of display clients to show the mode of a part of map respectively.As shown in Figure 1, the display screen of all display clients formation combination that is stitched together, thereby complete demonstration map.
Traditional technology, each display client at first shows the base map of map, when needs when base map adds focus, the control service end sends a hot spot data respectively to each display client, display client is deposited into the self EMS memory chained list with described hot spot data, and according to ranks position calculation of living in residing scope on map, the focus from the hot spot data of storing in the intercepting respective range is also played up demonstration.
In such scheme, each display client has all hot spot datas of self and other display clients, when base map translation or convergent-divergent, can realize showing fast according to self scope, but cause serious performance burden when hot spot data to be shown is too much, can for single display client, cause display performance to descend.
Summary of the invention
Based on above-mentioned situation, the present invention proposes the distributed display packing of a kind of map, device and combination system, to accelerate the speed that display client shows map.
A kind of combination system comprises control service end and a plurality of display client,
Also comprise the data, services end,
Described Control Server sends the hot spot data bag to described data, services end, and sends the order of interpolation focus to each described display client;
Described hot spot data bag is received and resolved to described data, services termination;
After described display client is received the order of described interpolation focus, obtain corresponding hot spot data and play up demonstration from described data, services end, corresponding hot spot data and described display client residing ranks position on combination adapts.
The distributed display packing of a kind of map comprises step:
Receive and add the focus order;
Obtain hot spot data;
Ranks distribution according to display client is divided described hot spot data;
Hot spot data after dividing is distributed to corresponding display client play up demonstration.
The distributed display device of a kind of map comprises:
The order receiver module is used for receiving the order of interpolation focus;
Data acquisition module is used for obtaining hot spot data;
Data are divided module, are used for according to the ranks distribution of display client described hot spot data being divided;
The distribution display module, the hot spot data after being used for dividing is distributed to corresponding display client and is played up demonstration.
A kind of combination system comprises the distributed display device of above-mentioned map.
The distributed display packing of map of the present invention, device and combination system, all display clients share a hot spot data, and when adding focus, hot spot data is divided, be the focus in each display client distribution respective range, each display client is played up demonstration to corresponding focus respectively.So, reduce the EMS memory occupation of display client, alleviated the load, particularly hot spot data amount of network transmission when big, can obviously improve the display performance of total system.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further described in detail.Should be appreciated that embodiment described herein only in order to explain the present invention, does not limit protection scope of the present invention.
The distributed display packing of map of the present invention as shown in Figure 2, comprises step:
The focus order is added in step S101, reception;
Step S102, obtain hot spot data;
Step S103, distribute according to the ranks of display client described hot spot data is divided;
Step S104, the hot spot data after will dividing are distributed to corresponding display client and are played up demonstration.
This method has shown base map at display client, need increase the situation of focus at base map.In order to reduce hot spot data to the taking of display client internal memory, this method leaves the hot spot data that obtains in the particular data service end, and this data, services end can be the device that hard disk, database, internal memory container etc. have memory function.Ranks distribution according to display client is divided into corresponding umber with hot spot data, and each part distributed to corresponding display client, and display client is shown to corresponding hot spot data interpolation on the corresponding base map, finishes focus and adds task.
As a preferred embodiment, described hot spot data is the hot spot data on the GIS map.
The distributed display device of map of the present invention as shown in Figure 3, comprising:
The order receiver module is used for receiving the order of interpolation focus;
Data acquisition module is used for obtaining hot spot data after described order receiver module receives the order of described interpolation focus;
Data are divided module, are used for according to the ranks distribution of display client the described hot spot data that described data acquisition module obtains being divided;
The distribution display module, the hot spot data after being used for dividing is distributed to corresponding display client and is played up demonstration.
As a preferred embodiment, described hot spot data is the hot spot data on the GIS map.
As a preferred embodiment, the described hot spot data that described data acquisition module will obtain is stored in the data, services end.
The distributed display device applications of above-mentioned map in traditional combination system, is namely formed combination of the present invention system.
Combination of the present invention system comprises control service end and a plurality of display client, as shown in Figure 4, also comprises the data, services end.
Described Control Server sends the hot spot data bag to described data, services end, and sends the order of interpolation focus to each described display client; Described hot spot data bag is received and resolved to described data, services termination; After described display client is received the order of described interpolation focus, obtain corresponding hot spot data and play up demonstration from described data, services end, corresponding hot spot data and described display client residing position on combination adapts.
As a preferred embodiment, described data, services end is database or internal memory container.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
