Description
Technical Field
The invention relates to the technical field of data services, in particular to a method, a device, equipment and a medium for prompting administrative division switching.
Background
In the process of navigating by using the mobile phone navigation application by the user, when the administrative division where the user is located is changed, the change of the administrative division and the current administrative division where the user is located need to be prompted in a voice mode. Typical scenarios are: when the user drives the car to enter the Tongzhou area of Beijing city from the sunny area of Beijing city, the navigation automatically carries out voice announcement prompting to inform the user that 'you have entered the Tongzhou area of Beijing city'.
A system structure of an administrative division switching navigation broadcasting prompt in the conventional navigation is shown in fig. 1. The system consists of a mobile phone navigation application, a mobile communication network and a server.
The server stores a plurality of administrative region data in a database (data file); the server provides an online administrative division calculation service module/interface, calculates an administrative division where the longitude and latitude are located according to the longitude and latitude carried in the terminal request and the inclusion relation of the longitude and latitude and the administrative division data, and returns the administrative division to the terminal; navigation data provided by a map provider comprises administrative division data, one surface data (a closed longitude and latitude sequence, such as 'X1, Y1; X2, Y2; X3, Y3 … Xn, Yn') corresponds to one administrative area, and each administrative area is composed of a plurality of surface shape data.
A user position timing acquisition module in the mobile phone navigation application periodically acquires the current longitude and latitude coordinates; and the user position cache checking module checks whether the position deviation reaches a preset threshold value according to the current position and the position of the last judgment period of the user, and if so, the online administrative division acquiring module is informed to send a request to the server side to acquire the administrative division codes and names corresponding to the longitude and latitude. And the administrative division switching judgment module judges whether the current administrative division is consistent with the administrative division stored in the previous judgment period, if not, the administrative division is changed, and the navigation broadcasting module is informed to perform voice broadcasting.
The mobile communication network is used as a communication channel between the mobile phone navigation application and the server side.
The prior art scheme has two disadvantages:
the first disadvantage is that: the method for acquiring the current administrative division and switching judgment by the mobile navigation application networking wastes network flow and terminal power consumption, and meanwhile, the server-side heavy load response speed is low.
The mobile phone navigation application needs to be connected with a network to initiate a network request to a server to acquire an administrative division corresponding to the current longitude and latitude, so that network traffic is wasted, and the power consumption of the mobile phone terminal is obviously increased due to frequent networking requests. For mobile phone navigation application, reading GPS data, keeping a screen lighted and navigating and broadcasting result in high power consumption, frequent networking in an online mode can increase terminal power consumption, and standby and service time of a mobile phone terminal is shortened.
The server side performs geographic geometry inclusion calculation on national administrative division data in the database according to the longitude and latitude requested by the terminal every time, calculates the administrative division where the longitude and latitude are located, and has high calculation intensity, so that the server side has high requirements on processing performance and depends on more or higher configured servers; on the other hand, the processing time delay of the server is long, so that the response speed is slow.
The second disadvantage is that: the mobile phone navigation application sets a fixed position deviation threshold value to trigger a request and a judgment mode, so that redundant requests and judgment are caused, network flow and terminal power consumption are wasted
Since the position offset threshold is a preset fixed value, the initiation of an online request and the judgment of an administrative division are triggered as long as the distance between the longitude and latitude of the current time and the longitude and latitude of the previous period reaches the threshold, so that useless requests and judgment are caused. Fig. 2 is a schematic diagram of redundancy request and judgment in a prior art scheme. In fig. 2, the left area is administrative division a, the right area is administrative division B, and the left route is the user navigation route. According to the prior art, B, C, E, E, F is a judgment point for whether an administrative division is switched, a request for acquiring the administrative division needs to be sent to a server, but a request for responding to the administrative division is A, and a terminal judges that the administrative division is not changed and does not need navigation voice broadcasting. Obviously, the request and determination at point B, C, D, E, F is redundant, wasting network traffic and terminal power consumption.
In summary, the administrative domain switching scheme in the prior art has the technical problems of traffic waste and high power consumption.

The following describes the embodiments of the present invention in detail with reference to the following specific embodiments:
the embodiment provides a method for partitioning and preprocessing national administrative division data according to a map grid, marking the map grid at an administrative division bordering boundary, and storing administrative division surface data of an attributive grid; the mobile phone navigation application can complete the acquisition of administrative division information based on the existing flow for acquiring map grid data, and judges the administrative division switching based on the administrative division attributes/information in the map grid data, thereby solving the problems of network flow waste and terminal power consumption in the prior art.
One embodiment of the invention provides a preprocessing of segmenting data of a plurality of administrative divisions according to a map grid. The scheme of the invention is further illustrated by taking fig. 4-1 and fig. 4-2 as examples. Fig. 4-1 is a diagram illustrating a pre-processing of partition of the administrative region data according to the map grid according to an embodiment of the present invention, and fig. 4-2 is a diagram illustrating a data storage surface in the administrative region boundary map grid data according to an embodiment of the present invention.
After preprocessing, two types of map grids 1) and 2) can be obtained.
1) The grid is completely located inside the administrative division, which is called "map grid inside the administrative division", and is referred to as "map grid inside" for short, see the area part enclosed by the boundary in fig. 4-1. For the internal map grid, because the administrative region division data belonging to the grid is the grid boundary, no additional surface data needs to be stored, and only the administrative region division attribute needs to be added to the grid. For example as in figure 4-1 of the drawings,
grid2208.gridType ═ inter; // Mark as internal map grid
Grid2208. encode 110105; // record the administrative division code to which it belongs
Grid2208 adname ═ administrative division name of sunny district// record in Beijing
Gridtype inter; // Mark as internal map grid
Adicode 110112, grid 2187; // mark belonging to the administrative division code
Adime, tokyo, municipality; // record name of administrative division
2) The grid is located at the boundary of the administrative division, and is called as an 'administrative division boundary map grid', and is called as a 'boundary map grid' for short, and is shown in gray parts of 4-1. For the boundary map grid, since administrative region area data belonging to the grid is not a grid boundary, all administrative region area information belonging to the grid and corresponding area data need to be stored. For example, Grid2209 in fig. 4-1, which spans two administrative divisions, so that the administrative division information of the two home grids is saved after the administrative division splitting pre-processing, see fig. 4-2.
Gridtype ═ border; // Mark as boundary map grid
Grid2209.adcode1 ═ 110105; // record code of administrative division 1
Grid2209. adname1. the name of the sunny district// record administrative district 1 in Beijing
Grid2209.ad polygon ═ x1, y 1; x2, y 2; x3, y 3; ..// record longitude and latitude sequence plane data of home grid of administrative division 110105, see Polygon110105 in FIG. 4-2
Grid2209.adcode2 ═ 110112; // record code of administrative division 1
Grid2209. adname2. the name of Tongzhou district// record administrative district 1 of Beijing City
Grid2209.ad polygon2 ═ x1, y 1; x2, y 2; x3, y 3; ..// record longitude and latitude sequence plane data of home grid of administrative division 110112, see Polygon110112 in FIG. 4-2
In practical application, multiple lines of political region data are organized in an array mode.
One embodiment of the invention provides a processing method and a specific algorithm flow for carrying out segmentation pretreatment on administrative division data according to a map grid. To further explain the scheme of the present invention by taking fig. 5 and fig. 6 as an example, for each administrative division, the internal map grid and the boundary map grid of the surface can be obtained through the following algorithm, the segmentation pretreatment of the administrative division data is completed, and further the segmentation pretreatment of the national administrative division data is completed, fig. 5 is an explanatory diagram of an algorithm flow for performing the segmentation pretreatment on the administrative data according to the map grid in an embodiment of the present invention, and includes diagrams 5-1, 5-2, 5-3, and 5-4.

5) Traverse SGridAnd judging the geometric relationship with the administrative district Polygon to obtain an internal map grid and a boundary map grid, which are shown in fig. 5-4.
Disjoint: abandon
Comprises the following steps: this map grid is the "internal map grid", the mark type and administrative division codes and names.
Intersecting: the map grid is a boundary map grid, intersecting surfaces are obtained through geometric calculation, and administrative division codes and names corresponding to the intersecting surfaces and the intersecting surfaces are stored in map grid data.
The present embodiment proposes a method for performing administrative division switching determination and broadcast based on administrative division data in map grid data.
After the administrative region section data are preprocessed and split according to the map grids, the internal map grids have administrative region attributes, and the administrative region section data belonging to the grids are stored in the boundary map grid data. The mobile phone navigation application finishes the acquisition of the administrative division information of the grid in the map grid data request process, the administrative division where the individual requests are located does not need to be frequently networked, the administrative division information can be judged and switched based on the map grid data, and compared with the prior art, the power consumption waste of network flow and frequently initiated network requests is obviously reduced. The method for judging and broadcasting the administrative division switching is as follows, and a flow chart is shown in fig. 6.
STEP 1: and periodically judging the current map grid number according to the current longitude and latitude, and if map data of the map grid number does not exist locally, acquiring the map grid number from a server (wherein the map grid number carries administrative division information after segmentation pretreatment).
Note: the standard process of obtaining the map grid data from the server does not increase extra power consumption.
STEP2, judging the type of the map grid where the current longitude and latitude is located:
case1 internal map grid, No processing required
case2, namely, judging the geometric inclusion relationship according to the current longitude and latitude and administrative division data stored in the grid map data, and determining the administrative division where the current longitude and latitude is located; and if the administrative division is different from the previous period, judging that the administrative division switching occurs, and triggering navigation broadcasting, such as 'you enter the Tongzhou area of Beijing city'.
Fig. 7 shows a specific example of the low-power consumption administrative division navigation broadcasting system according to the present invention. Fig. 7 is a diagram of an exemplary system configuration including a server, a handset navigation application, and a mobile communications network, in accordance with an embodiment of the present invention.
The administrative division grid segmentation preprocessing module of the server divides national administrative division plane data according to map grids, and stores the national administrative division plane data and vector map data subjected to grid segmentation preprocessing of the map data in the map grid data; the map grid data downloading module provides a map grid data downloading service and supports downloading of corresponding map grid data (including map data and administrative division attributes/information inside) according to the requested grid number.
A user position timing acquisition module in the mobile phone navigation application periodically acquires the current longitude and latitude coordinates of a user; the map grid data request module acquires map grid data (including administrative division attributes/information) from a server and stores the map grid data in the local; the local administrative district switching judgment module judges whether the administrative district is switched according to the map grid type and the information of the current longitude and latitude based on the map grid data, and if the administrative district is switched, the navigation broadcasting module is informed to broadcast.
The mobile communication network is used as a communication channel between the electronic map terminal and the service end.
Compared with the prior scheme, the advantages of the various embodiments of the invention at least comprise:
reducing the load of the server interface and the complex calculation: the administrative region is segmented and preprocessed according to grids, and is stored in map grid data together with vector map data, and the original map grid data downloading service can support system requirements; the server does not need to store the national administrative region section data and the calculation service thereof, and the calculation load and the power consumption of the server are reduced.
The network flow of the client and the power consumption of the terminal are reduced: the administrative division switching judgment is carried out based on the administrative division attributes/information downloaded to the map grid data of the local client, the administrative division switching judgment is not required to be carried out according to distance offset threshold value networking, the acquisition of the administrative division information of the local grid is completed by utilizing the existing map grid data request interface, and the client does not need to frequently network and independently request the administrative division information. Because the map grid data can be cached in the local client, the map grid data can be locally reused after being downloaded, and for the situation of repeated navigation in a fixed area (actually, a downloaded map grid or set), the administrative division switching judgment and the broadcast prompt which do not depend on the network can be realized, and the effect of reducing the power consumption is more obvious.
