Spirogram layer, carrying cost greatly reduce compared with grid tile and vector tile.
Refering to Fig. 4, the map interactive system of the transmission of electricity O&M, comprising:
Front end presentation layer 10, data business layer 11 and database 12, the database include cache layer.
The front end presentation layer 10 shows the requested transmission line information of user.
Wherein, the displaying can be to be output to Web User Interface to be shown；Specifically, front end presentation layer is for wrapping
Include the displaying of tile map, the displaying of toolbar, the displaying of VectorLayer.
The data business layer 11, responds the access operation of user, takes out tile map data and power transmission line from cache layer
Road VectorLayer data, and through map render engine renders, obtain transmission line information.
Wherein, the data business layer 11 includes tile map service and vector data service；
The access operation of the response user is the request at customer in response end, and the access operation is that request shows power transmission line
The relevant operation on road；It is understood that the client be with network connecting function and/or visual smart machine,
It is mainly used for the input of user information and the output of processing result etc..
In specific embodiment, the cache layer is Redis cache layer；Specifically, Redis database caches are common
Data, the VectorLayer GeoJSON data comprising used tile map data, route and pylon in nearest 7 days；
The map rendering engine is the OpenGL map rendering engine in conjunction with Mapnik geography information frame.
In a preferred embodiment, requested tile map is not present in cache layer in the data business layer 11
When data and/or transmission line of electricity VectorLayer data, tile map data and/or power transmission line are taken out from corresponding database 12
Road VectorLayer data；Wherein, the tile map data are stored in MongDB database, the transmission line of electricity polar plot number of plies
According to being stored in MySQL database.
In a preferred embodiment, the database 12, by the tile map data being currently accessed and transmission of electricity
Route VectorLayer data buffer storage continues caching to the cache layer.It should be noted that the tile that will be currently accessed
Map datum and transmission line of electricity VectorLayer data buffer storage or to continue caching to the cache layer be in cache layer there is no being asked
It is carried out in the case where the tile map data and/or transmission line of electricity VectorLayer data asked, therefore meets caching condition, wherein delaying
Deposit condition are as follows: the data of current request whether there is in Redis cache layer, there is no just being cached, exist then without behaviour
Make.It is understood that when request amount is big at some time point for the access operation, if request is all from MongoDB every time
Or taken out in MySQL database, it is too big to will cause input/output consumption, and the tile map number by will currently be accessed
According to transmission line of electricity VectorLayer data buffer storage or continue to be cached to cache layer, can reduce the consumption of input/output.
In specific embodiment, will can also set simultaneously in the time limit tile map data that not be accessed repeatedly and
Transmission line of electricity VectorLayer data buffer storage is removed from the cache layer to cache layer.It is understood that by removing caching
Data in layer, can reduce the data volume of cache layer, to reduce the data query time in the cache layer, improve number
According to processing speed.
Pass through the introduction of preferred embodiment above, additionally it is possible to reduce the consumption of input/output, and can be improved data processing
Speed.
In a preferred embodiment, the front end presentation layer 10 is also used to obtain tile map data and transmission line of electricity
VectorLayer data, specifically, the map of target area is carried out grade cutting on demand, from highest level down to lowest hierarchical level
A pyramid coordinate-system is formed, to obtain tile map data, the GPS data of transmission line of electricity will be imported, generate transmission of electricity
Route VectorLayer data.
It with reference to Fig. 5, Fig. 5 is disposed based on large screen interface provided by the present invention, a central map is core, left and right two
There is the icon module of statistical information in side, for showing various information.
To sum up, the present invention can be realized except frequent map interaction and dynamic management and running, additionally it is possible to and reduction input/
The consumption of output, and can be improved data processing speed.Meanwhile by directly drawing transmission line of electricity arrow on the basis of tile map
Spirogram layer, carrying cost greatly reduce compared with grid tile and vector tile.
Those of ordinary skill in the art will appreciate that realizing all or part of the process in above-described embodiment method, being can be with
Relevant hardware is instructed to complete by computer program, the program can be stored in a computer-readable storage medium
In, the program is when being executed, it may include such as the process of the embodiment of above-mentioned each method.Wherein, the storage medium can be magnetic
Dish, CD, read-only memory (Read-Only Memory, ROM) or random access memory (Random Access
Memory, RAM) etc..
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
