Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
An electronic fence refers to the coverage area of a site defined on a map, and is a closed irregular polygon. In the prior art, an electronic fence is applied to the field of express delivery billing, specifically, an electronic map and an electronic fence technology are applied to a billing and delivery link, longitude and latitude of an addressee are obtained through the electronic map, and then a website code and a salesman code corresponding to the longitude and latitude are obtained through the electronic fence. The method relates to a process of loading an electronic fence on an electronic map, and the existing electronic fence loading method is as follows: in a one-time full-loading mode of the electronic fence, the rendering method causes repeated data loading, the loading speed is slow, and the requirement on the performance of the server is high.
In view of the above drawbacks, in the embodiment of the present invention, only the electronic fence in the dragging area is loaded and rendered, so as to change the conventional one-time full-load electronic fence, thereby increasing the loading speed of the electronic fence. The technical solution of the present invention will be described below by way of specific examples.
The first embodiment is as follows:
the present embodiment provides an electronic fence loading method, a flowchart of which is shown in fig. 1, and specifically includes the following steps.
S100: and performing geohash coding on the longitude and latitude data of the preset position points of each electronic fence, and storing the geohash coding.
S200: and performing geohash coding on the longitude and latitude data of the central point of the dragging area.
S300: and screening the geohash codes positioned in the dragging area through the geohash.
S400: and loading the electronic fence corresponding to the screened geohash code.
The above steps will be explained below.
In step S100, geohash encoding is performed on the longitude and latitude data of the preset position point of each electronic fence, and the geohash encoding is stored. The method specifically comprises the following steps:
s101: and encoding the longitude and latitude data of the preset position points of each electronic fence into a character string with a preset length through a geohash algorithm.
S102: and forming a record by using the longitude and the latitude of the preset position point of each electronic fence and the character string of the corresponding code.
S103: the records are sorted and stored according to the character string in dictionary order.
First, explanation is made on the geohash algorithm: the geohash is a character string representing two coordinates of longitude and latitude, that is, the geohash can convert longitude and latitude information into a character string code which can be sorted and compared. The prefix of the code may represent a larger area, for example wx4g0ec1, its prefix wx4g0e representing a larger range including the code wx4g0ec 1. The application also utilizes the characteristic to search the electronic fence belonging to the dragging area. The encoding rule related to the present embodiment is a base32 encoding rule, and a base32 encoding rule diagram is shown in fig. 2.
In step S101, a string of a preset length is a geohash code of a preset length, that is, the length of the geohash code, where the length is a geohash code length selected according to an actual application requirement and according to a geohash precision table, and the geohash precision table is shown in fig. 3, where geohash length represents the geohash code length, lat bits represents a latitude bit number, ng bits represents a longitude bit number, lat error represents a latitude error, ng error represents a longitude error, and km error represents a distance error.
As can be seen from fig. 3, the larger the geohash coding length is, the higher the error precision is, for example, when the geohash coding length is 1, the distance error is 2500 km; when the geohash coding length is 2, the distance error is 630 km; when the refined geohash coding length is 3, the distance error is 78 km; when the geohash coding length is 4, the distance error is 20 km; when the geohash coding length is 5, the distance error is 2.4 km; when the geohash coding length is 6, the distance error is 610 m; when the geohash coding length is 7, the distance error is 76 m; the geohash code length is 8, the range error is 19 m.
The basic principle of the geohash coding is: firstly, the longitude and latitude are converted into binary system, secondly, the longitude and latitude of the binary system are combined, and finally, the encoding is carried out according to base 32. The following warp and weft values are given: (116.389550, 39.928167) illustrates the geohash algorithm.
The process of approximating and coding the latitude 39.928167 with the latitude interval of the earth as [ -90, 90] comprises the steps a-h.
Step a, dividing the interval between-90 and 90 into-90 and 0, 0 and 90, namely left and right intervals, and determining 39.928167 as right interval 0 and 90 marked as 1;
step b, dividing the interval [0, 90] into two intervals [0, 45 ], [45, 90], and determining 39.928167 as belonging to the left interval [0, 45 ] and marking as 0;
c, recursion the above process 39.928167 always belongs to a certain interval [ a, b ], and the interval [ a, b ] is always reduced with each iteration and approaches 39.928167 more and more;
step d, recording 0 if the given latitude 39.928167 belongs to the left interval and 1 if it belongs to the right interval, the length of the sequence being related to the number of divisions of the given interval, as shown in fig. 4;
step e, similarly, the earth longitude interval is [ -180, 180], and longitude 116.389550 may be encoded. By the above calculation, the longitude-generated code is 110100101100010, and the latitude-generated code is 101110001100011;
step f, merging: longitude is set at even number, latitude is set at odd number, and 2 strings of codes are combined to generate a new string as shown in FIG. 5;
step g, according to fig. 2, firstly, 11100111010010001111000001101 is converted into decimal corresponding to 28, 29, 4, 15, 0, 13, the base32 code corresponding to decimal is wx4g0e, and the code is used as the geohash code of the latitude and longitude.
Let < wx4g0e, (116.389550, 39.928167) > be one record and sort and store < wx4g0e, (116.389550, 39.928167) > in lexicographic order according to wx4 go.
And step S101 to step S103 are carried out to complete the geohash coding and storage of the longitude and latitude data of the preset position points of each electronic fence.
In step S200, geohash encoding is performed on the longitude and latitude data of the central point of the dragging area; the method comprises the following steps that a dragging area takes a query position point as a central point, a query distance as a radius to form a circular dragging area, and geohash coding is carried out on longitude and latitude data of the central point of the dragging area, and the method specifically comprises the following steps:
selecting a corresponding geohash coding length for the query distance range according to the geohash precision table;
and performing the geohash coding on the query position point according to the selected geohash coding length.
For a specific process of performing geohash coding on the longitude and latitude data of the central point of the dragging area, reference may be made to the above steps a to g, which are not described herein again.
In step S300, the geohash code located in the dragging area is screened through the geohash, which specifically includes the steps of: searching for the geohash codes of the longitude and latitude of the electronic fence preset position point matched with the geohash codes of the inquiry position point, and screening out the geohash codes meeting preset matching conditions.
Specifically, matching is performed by matching string strings of the geohash codes, prefixes identical to the strings are used as preset matching conditions, and the geohash codes in the prefixes of the identical strings are selected as the result of screening, for example, wx4g0ec1, and the prefix wx4g0e of the geohash codes represents a larger range including the code wx4g0ec1, so that all the geohash codes of the same prefix wx4g0e can be used as the result of screening.
In an embodiment, the fence preset location point includes a longitude and latitude of a center point of the fence, in which case, the foregoing steps S100 to S400 are only performed for the fence whose longitude and latitude of the center point are located in the dragging area.
In a special case, for example, when the area of the electronic fence is large, and the electronic fence intersects with the dragging area, but the longitude and latitude of the center point of the electronic fence do not exist in the dragging area, the electronic fence cannot be loaded. For this situation, the electronic fence loading method is further optimized in this embodiment, and through the optimization, the electronic fences in the dragging area and the electronic fences intersecting with the dragging area can be loaded. The optimization process is as follows:
before the step S100, a step of dividing each electronic fence is further included, and further, the preset position point of the electronic fence further includes a longitude and latitude of a center point of the divided portion.
Preferably, each electronic fence is divided into a plurality of triangles by adopting a triangle division algorithm, and the preset position points of the electronic fence further comprise the longitude and latitude of the center point of each triangle. Compared with the method of singly carrying out the geohash coding on the longitude and latitude of the central point of each electronic fence, the optimization process increases the number of the geohash coding positions in the electronic fence area, so that the loading number of the electronic fences can be increased as much as possible in a certain dragging area.
For example, as shown in fig. 6, a reference sign a is a dragging area, reference signs B, C are respectively different electronic fences, where a1 is a central point of the dragging area, a point B1 is a central point of the electronic fence B, a point C1 is a central point of the electronic fence C, and points D1, D2, D3 and the like are central points of triangular areas divided by partial areas of the electronic fence C, and if only geohash coding is performed on longitude and latitude of the central point of the electronic fence, only the electronic fence B can be loaded, and the electronic fence C cannot be loaded; if the electronic fence is divided into triangles based on expansion, and the center point of the divided triangle is coded by the geohash at the same time, the electronic fence C intersected with the dragging area A can be loaded through any point of the matched points D1, D2 and D3, so that the electronic fence can be loaded to the maximum extent in a certain dragging area.
Compared with the traditional one-time full-load method, the electronic fence loading method provided by the embodiment is only used for loading by taking the dragging area as the loading range, for example, the electronic fence in the dragging area is loaded, and the electronic fence outside the dragging area is not loaded, so that the loading speed of the electronic fence is increased, the use experience is improved, the high-performance configuration requirement on the server is reduced, and the cost is reduced.
In the field of express delivery service, all network points in the country maintain the electronic fences for picking up/sending the items of the business personnel at the network points, for example, when the items need to be sent, a match is dragged on an electronic map, the electronic fences in the dragging area are loaded, then the longitude and latitude of the items to be sent are judged to fall in the range of the electronic fences of the business personnel at the network points through a ray method and an R tree index, and then the item sending efficiency is improved.
Example two:
based on the first embodiment, the present embodiment provides an electronic fence loading apparatus, whose schematic diagram is shown in fig. 7, and includes a data preprocessing module 100, a screening module 200, and a loading module 300.

Further, the data preprocessing module 100 includes:

The screening module 200 is configured to screen the geohash code located in the drag area by the geohash. In this embodiment, the screening module 200 searches for a geohash code of the longitude and latitude of the preset location point of the electronic fence, which is matched with the geohash code of the query location point, and screens out the geohash code meeting the preset matching condition.
Specifically, matching is performed by matching string strings of the geohash codes, prefixes identical to the strings are used as preset matching conditions, and the geohash codes in the prefixes of the identical strings are selected as the result of screening, for example, wx4g0ec1, and the prefix wx4g0e of the geohash codes represents a larger range including the code wx4g0ec1, so that all the geohash codes of the same prefix wx4g0e can be used as the result of screening.
The loading module 300 is configured to load the electronic fence corresponding to the screened geohash code.
Compared with the traditional disposable full-load loading, the electronic fence loading device provided by the embodiment is only used for loading by taking the dragging area as a loading range, for example, the electronic fence in the dragging area is loaded, and the electronic fence outside the dragging area is not loaded, so that the loading speed of the electronic fence is increased, the use experience is improved, the high-performance configuration requirement on the server is reduced, and the cost is reduced.
