[0066] Embodiment 1

[0067] Figure 1 This is a flowchart of a method for generating a stroke emergency range provided by the first embodiment of the present invention. This embodiment can be applied to the situation of automatically and accurately generating a stroke emergency range when deploying a stroke institution. The method can be executed by a stroke emergency range generating device. The stroke emergency range generating device can be implemented in the form of hardware and / or software. The stroke emergency range generating device can be configured in an electronic device, and the electronic device can be a personal computer or a distributed server. Figure 1 As shown, the method includes:

[0068] S110. Obtain coordinates of multiple emergency agencies.

[0069] The coordinates of the emergency agency are obtained from the preset map database. Considering the legality and coordinate system of the use of map services, the interface (API) of the National Geographic Information Public Service Platform can be used as an example. In addition, the map query interface provided by a third-party platform can also be used. The third-party platform can be a map application that is currently available on the market.

[0070] The coordinates of the emergency agency are queried through the interface according to the known name of the emergency agency. The coordinates of the emergency agency can be longitude and latitude.

[0071] This application stores data through a preset database, and after obtaining the coordinates of the emergency agency, the coordinates of the emergency agency are persisted to the preset database. Optionally, the preset database can be an ElasticSearch database. The ElasticSearch database is used to support distributed data persistence and call services. Optionally, this solution adopts a multi-task collection scheduling mode, and each step can independently and concurrently execute the collection task, and persist the process data to the preset database. Reduce the pressure on the navigation interface through a period of time scheduling, and improve the accuracy of the emergency circle with the amount of data.

[0072] The preset database can open the interface of adding, deleting and modifying the basic information of the emergency agency to the emergency agency, so as to facilitate the change and management of the emergency agency.

[0073] Optionally, an index of basic information of emergency agencies can be pre-constructed in a preset database, as shown in Table 1, which contains fields for emergency agency code, emergency agency name, longitude and latitude, emergency agency type, and whether the longitude and latitude collection has been completed. The emergency agency can fill in the content in the basic information index of the emergency agency, where longitude and latitude are the coordinates of the emergency agency, and the emergency agency does not need to fill it in. During the implementation of this embodiment, the preset map database is accessed according to the name of the emergency agency in the basic information index of the emergency agency to query the coordinates of the emergency agency, and the coordinates of the emergency agency returned by the preset map database are persisted to the basic information index of the emergency agency. After the query, the status of whether the longitude and latitude collection is completed is modified.

[0074] The emergency agency code is used to uniquely identify the emergency agency. The emergency agency type can be divided into first-level emergency agencies and second-level emergency agencies. Optionally, a first-level emergency agency is represented by "1" and a second-level emergency agency is represented by "2". The collected status field can be used to indicate whether the collection of the emergency agency coordinates has been completed. If completed, the collected status is "true", if not completed, the collected status is "false".

[0075] Table 1

[0076]

[0077] S120. Determine points of interest within a preset range according to the coordinates of the emergency agency.

[0078] After determining the coordinates of the emergency agency, search for points of interest (POI points) around the emergency agency with the coordinates of the emergency agency as the center, as points of interest subordinate to the emergency agency. Points of interest can be searched through a preset map database. The found point of interest information is persisted to a preset database. During the persistence process, the emergency agency information to which the point of interest belongs is recorded, and the information may include the emergency agency code and the type of the emergency agency. Optionally, this step can be implemented in a distributed manner to increase processing speed.

[0079] S130: Determine a travel isosurface according to the travel time from the point of interest to the corresponding emergency agency.

[0080] Get the travel time from each point of interest to the emergency agency to which it belongs. You can query the route from the point of interest to the emergency agency to which it belongs and the time taken on the route as the travel time through the interface provided by the preset map database. If there are multiple routes, the time corresponding to the shortest route is selected as the travel time.

[0081] After obtaining the travel time from each point of interest to the emergency agency, the travel isosurface formed by the points of interest can be determined with the emergency agency as the center. The points of interest with the same travel time to the emergency agency are used as points to form a travel isosurface. Each emergency agency can have multiple isosurfaces. For example, there are multiple travel isosurfaces with a travel time of 10 minutes, a travel time of 20 minutes, a travel time of 30 minutes, etc.

[0082] S140. Determine the stroke emergency rescue scope according to the travel isosurfaces of multiple emergency rescue agencies.

[0083] The isosurfaces of adjacent emergency agencies are spliced ​​together to obtain the stroke emergency care scope.

[0084] The technical solution of the embodiment of the present invention can determine the points of interest around the emergency agency after obtaining the coordinates of the emergency agency, and determine the travel isosurface based on the travel time from the points of interest to the emergency agency, and then determine the stroke emergency range based on the travel isosurface, thereby realizing accurate statistics of the stroke emergency range.

[0085] Embodiment 2

[0086] Figure 2 It is a flowchart of a method for generating a stroke emergency rescue range provided by Embodiment 2 of the present invention. The relationship between this embodiment and the above-mentioned embodiment is to further explain step S120.

[0087] like Figure 2 As shown, the method includes:

[0088] S210. Obtain coordinates of multiple emergency agencies.

[0089] S220: Determine a correlation matrix according to the coordinates of the emergency agency and a preset interval, wherein a plurality of coordinate points are arranged in the correlation matrix according to the preset interval.

[0090] Optionally, determining the association matrix according to the coordinates of the emergency agency and the preset interval can be implemented in the following manner:

[0091] The coordinates of the emergency agency in the emergency agency basic information index are searched through the interface provided by the preset database. Each coordinate of the emergency agency is processed as follows: taking the coordinate of the emergency agency as the center point, extending a plurality of preset interval units in the four directions of east, west, south and north respectively, setting a coordinate point in each preset interval, and obtaining an association matrix.

[0092] like Figure 3As shown, assuming that the emergency agency is a stroke hospital, with the stroke hospital as the center, a matrix of 2n+1*2n+1 (n is more accurate, n is 50) is generated with the preset interval d (the larger the d value, the higher the accuracy, d is 0.2) in both horizontal and vertical directions. Among them, the geohash provided by the preset map server can be used to calculate that the true distance of a longitude difference of 0.1 is about 1000m, and the distance of a latitude difference of 0.1 is about 1113m.

[0093] S230: Obtain one or more points of interest around each coordinate point.

[0094] Optionally, obtaining one or more points of interest around each coordinate point can be implemented in the following manner: according to the coordinates of the coordinate point, querying one or more points of interest closest to the coordinate through the query interface of the map application

[0095] After the matrix is ​​determined, each store set in the matrix is ​​used as a coordinate point. Through the reverse geocoding query (POI query) service interface provided by the preset map database, the points of interest around the coordinate point are queried.

[0096] like Figure 4 As shown, assuming that only the interest points closest to the coordinate point are queried, each coordinate point corresponds to one interest point.

[0097] Optionally, the interest points around the coordinate point can be queried, and the distances between the interest points and the coordinate point can be sorted, and multiple interest points with smaller distances in the sorting can be used as the final selected interest points.

[0098] After finding the interest point, the interest point is persisted to the preset database. Exemplarily, as shown in Table 2, the interest point coordinates are persisted through the interest point index.

[0099] Table 2

[0101] S240: Determine a travel isosurface according to the travel time from the point of interest to the corresponding emergency agency.

[0102] S250: Determine the stroke emergency rescue scope according to the travel isosurfaces of multiple emergency rescue agencies.

[0103] The technical solution of this embodiment can generate an association matrix with the coordinates of each emergency agency as the center, and controllably search for one or more points of interest through the association matrix, so that the density and accuracy of the points of interest can be controlled according to needs. The itinerary isosurface obtained on this basis is more accurate, thereby improving the accuracy of the stroke emergency range.

[0104] Embodiment 3

[0105] Figure 5 It is a flowchart of a method for generating a stroke emergency rescue range provided by Embodiment 3 of the present invention. The relationship between this embodiment and the above-mentioned embodiment is to further explain step S130.

[0106] like Figure 5 As shown, the method includes:

[0107] S310, obtaining coordinates of multiple emergency agencies.

[0108] S320: Determine points of interest within a preset range according to the coordinates of the emergency agency.

[0109] S330: Determine the travel time from each point of interest to the corresponding emergency agency in at least one time period through the navigation interface of the map service.

[0110] Furthermore, in one implementation, before S330, the method further includes: interpolating coordinate points according to coordinate points within the target time period; and filtering outliers according to travel time of the interpolated coordinate points.

[0111] Determining the itinerary isosurface based on the points of interest may result in the itinerary isosurface being inaccurate due to the limited number of points of interest. To address this issue, an embodiment of the present invention provides an interpolation method. Interpolation is performed between points of interest. The interpolation algorithm may use the Kriging interpolation method. After obtaining the interpolation coordinate points, in order to further determine the stability of the travel time, the travel time from the interpolation coordinate points to the coordinates of the first aid agency to which they belong is obtained. Abnormal travel time is excluded according to the travel time threshold. Then, normalization processing is used to obtain the itinerary isosurfaces of each point of interest and the difference coordinate points to the first aid agency to which they belong.

[0112] The itinerary information of each point of interest may be persisted. Optionally, it may be stored by an itinerary index of the point of interest as shown in Table 3.

[0113] Table 3

[0114] Fields illustrate type Target time period Collection timestamp Date code Emergency agency code String Point of interest coordinates lonlat Poi longitude and latitude Earth coordinate point geo_point Type Type of emergency agency integer Duration Time to arrive at emergency services integer

[0115] S340: Determine at least one travel isosurface according to the travel time in a target time period, where the target time period is any one of the at least one time period.

[0116] In the above implementation, S340, determining at least one travel isosurface according to the numerical value of the travel time in the target time period, can be implemented as follows:

[0117] At least one travel isosurface is defined in the target time period according to the filtered interpolated coordinate points and the travel time of the points of interest.

[0118] Since the best emergency treatment time for stroke is 1 hour and the road conditions change over time, the travel time in different time periods is different. Therefore, we use one hour as an interval and take each hour of the 24 hours as a target time period. We draw the travel isosurface for each time period. In subsequent output, we can retrieve the travel isosurface of the corresponding time period according to the time.

[0119] When determining the itinerary isosurface, the itinerary index of the points of interest in the preset database can be accessed to obtain the travel time through distributed computing, thereby realizing distributed computing of the itinerary isosurface. The obtained itinerary isosurface can be persisted through the isosurface index shown in Table 4. The itinerary isosurface stores the multiple points of interest or interpolated coordinate points it contains through a polygonal data structure.

[0122] S350: Determine the stroke emergency rescue scope according to the travel isosurfaces of multiple emergency rescue agencies.

[0123] The technical solution of this embodiment can interpolate the points of interest, and the boundaries of the polygons formed by the interpolated points of interest are smoother, and the travel isosurface is more accurate.

[0124] Embodiment 4

[0125] Figure 6 It is a flowchart of a method for generating a stroke emergency rescue range provided by Embodiment 4 of the present invention. The relationship between this embodiment and the above-mentioned embodiment is to further explain step S140.

[0126] like Figure 6 As shown, the method includes:

[0127] S410. Obtain coordinates of multiple emergency agencies.

[0128] S420: Determine points of interest within a preset range according to the coordinates of the emergency agency.

[0129] S430: Determine a travel isosurface according to the travel time from the point of interest to the corresponding emergency agency.

[0130] S440. Obtain the travel isosurface of the adjacent first-level emergency agencies.

[0131] S450, splicing the travel isosurfaces of adjacent first-level emergency agencies to obtain a stroke emergency range.

[0132] like Figure 7 As shown in the figure, the travel isosurfaces of the first-level emergency agencies that are closer are spliced ​​and the overlapping areas are merged.

[0133] S460: Obtain the isosurface of the secondary emergency care institutions adjacent to the stroke emergency care scope.

[0134] S470: If the isosurface of the secondary emergency agency overlaps with the stroke emergency scope, the overlapping area is divided into the stroke emergency scope.

[0135] like Figure 8 As shown, the isosurface of the second-level emergency agency is spliced ​​with the isosurface of the merged first-level emergency agency. If there is an overlapping part, the overlapping part is included in the scope of the first-level emergency agency.

[0136] Furthermore, it also includes:

[0137] The stroke emergency care scope in each time period is stored; when the map is output, the stroke emergency care scope is superimposed on the image base map of the map.

[0138] The data of the scope of the first-level emergency agencies and the scope of the second-level emergency agencies at each time are published to the GeoServer server, and the scope of the first-level cluster is changed to red, and the scope of the second-level emergency is changed to yellow. The interface uses Openlayer technology to overlay the web map service on the image base map for display. Users can interactively complete the query and analysis of the national emergency scope at each time through options such as timeline and emergency circle time on the interface.

[0139] The technical solution of this embodiment can determine the stroke emergency scope of different levels in different time periods according to the level of the emergency agency, and accurately determine the stroke emergency scope for each time period. In addition, by overlaying the display on the map, the obtained stroke emergency scope can be combined with the image base map of the map, which is convenient for users to view and improves ease of use.
