[0035] Embodiment 1

[0036] Figure 1It is a flowchart of a sensitive area proximity warning method provided according to Example 1 of the present invention. This embodiment can be applied to determine whether a monitored object in a preset monitoring area is close to a sensitive area. The method can be executed by a sensitive area proximity warning device. The sensitive area proximity warning device can be implemented in the form of hardware and / or software. The sensitive area proximity warning device can be configured in an electronic device such as a computer.

[0037] like Figure 1 As shown, a sensitive area approaching warning method disclosed in this embodiment includes:

[0038] S110, obtaining a target longitude and latitude set corresponding to the target sensitive area, and using a geospatial library to construct a target geospatial image corresponding to the target sensitive area according to the target longitude and latitude set.

[0039] In this embodiment, the target sensitive area may be an area that no unauthorized persons are allowed to enter. The target longitude and latitude set may be a set of longitude and latitude of each point on the target sensitive area.

[0040] In this step, specifically, one of the multiple candidate coordinate system numbers can be selected as the target coordinate system number, and the geospatial library can be used to construct a target geospatial image corresponding to the target sensitive area according to the target longitude and latitude set and the target coordinate system number. There can be multiple candidate coordinate system numbers, such as EPSG:4326 for representing the geocentric coordinate system and EPSG:3857 for representing the Mercator projection coordinate system.

[0041] S120: Determine a buffer area corresponding to the target sensitive area according to the target geographic space image and the set proximity distance.

[0042] In this embodiment, the buffer area may be an area surrounding the target sensitive area. The buffer area may be used to send warning information to the user before the monitored object enters the target sensitive area.

[0043] In this step, specifically, the buffer zone analysis method in geographic spatial analysis can be used to determine the buffer zone surrounding the target sensitive area according to the set proximity distance.

[0044] Optionally, a buffer area corresponding to the target sensitive area is determined according to the target geospatial image and a set proximity distance, including: determining a first buffer area corresponding to the target sensitive area according to the target geospatial image and a first preset proximity distance; determining a first buffer area to be processed corresponding to the target sensitive area according to the target geospatial image and a second preset proximity distance, and processing the first buffer area to be processed according to the first buffer area to obtain a second buffer area; wherein the first buffer area to be processed includes the first buffer area and the second buffer area; determining a second buffer area to be processed corresponding to the target sensitive area according to the target geospatial library and a third preset proximity distance, and processing the second buffer area to be processed according to the first buffer area to obtain a third buffer area; wherein the second buffer area to be processed includes the first buffer area and the third buffer area.

[0045] In this embodiment, the first preset proximity distance is smaller than the second preset proximity distance, and the second preset proximity distance is smaller than the third preset proximity distance. The first buffer area includes the first buffer area and the second buffer area, and the second buffer area includes the first buffer area to be processed and the third buffer area. The first preset proximity distance, the second preset proximity distance, and the third preset proximity distance can be determined according to user needs and the longitude and latitude of each point on the target geospatial image. For example, the first preset proximity distance can be set to 200 meters, the second preset proximity distance can be set to 500 meters, and the third preset proximity distance can be set to 1000 meters.

[0046] Specifically, the area to be cropped in the first buffer area to be processed can be determined based on the first buffer area, and the area to be cropped in the first buffer area to be processed can be eliminated to obtain the second buffer area. The area to be cropped in the second buffer area to be processed can be determined based on the first buffer area to be processed, and the area to be cropped in the second buffer area to be processed can be eliminated to obtain the third buffer area.

[0047] S130, obtaining a buffer zone longitude and latitude set corresponding to the buffer zone, and generating a buffer geospatial image corresponding to the buffer zone according to the buffer zone longitude and latitude set.

[0048] In this step, specifically, one of the multiple candidate coordinate system numbers can be selected as the buffer coordinate system number, and a buffer geospatial image corresponding to the buffer area can be constructed using the geospatial library according to the buffer latitude and longitude set and the buffer coordinate system number.

[0049] S140, obtaining the actual longitude and latitude corresponding to each monitoring object in the preset monitoring area, and the buffered longitude and latitude of each point on the buffered geographic space image, and determining whether to send a warning message to the user that the monitoring object is close to the target sensitive area based on the comparison result of the actual longitude and latitude and the buffered longitude and latitude.

[0050] In this step, specifically, movable objects that appear in the preset monitoring area can be used as monitoring objects, and the actual latitude and longitude of the monitoring objects can be obtained. The preset monitoring area includes a target sensitive area and a buffer area, and movable objects are not limited to people and animals that are not allowed to enter the target sensitive area.

[0051] Then, it can be determined in turn whether the actual longitude and latitude and each buffer longitude and latitude are equal within the error range, and when the actual longitude and latitude and any buffer longitude and latitude are equal within the error range, it is determined that the monitoring object corresponding to the actual longitude and latitude is within the buffer area. At this time, an early warning message that the monitoring object is close to the target sensitive area can be sent to the user.

[0052] Optionally, the buffer longitude and latitude of each point on the buffer geospatial image is obtained, and based on the comparison results between the actual longitude and latitude and each buffer longitude and latitude, it is determined whether to send warning information about the monitored object approaching the target sensitive area to the user, including: obtaining a first buffer geospatial image corresponding to the first buffer area, and the first buffer longitude and latitude of each point on the first buffer geospatial image, and when the actual longitude and latitude are equal to any first buffer longitude and latitude within an error range, sending emergency warning information about the monitored object approaching the target sensitive area to the user; obtaining a second buffer geospatial image corresponding to the second buffer area, and the second buffer longitude and latitude of each point on the second buffer geospatial image, and when the actual longitude and latitude are equal to any second buffer longitude and latitude within an error range, sending important warning information about the monitored object approaching the target sensitive area to the user; obtaining a third buffer geospatial image corresponding to the third buffer area, and the third buffer longitude and latitude of each point on the third buffer geospatial image, and when the actual longitude and latitude are equal to any third buffer longitude and latitude within an error range, sending general warning information about the monitored object approaching the target sensitive area to the user.

[0053] The error range may be a range within which the point position corresponding to the actual longitude and latitude on the buffered geospatial image can be determined.

[0054] The advantage of such a setting is that by determining multiple buffer areas corresponding to the target sensitive areas and sending different levels of warning information to the user when the monitored object enters different buffer areas, the user can relatively accurately determine the location of the monitored object based on the warning information, thereby facilitating the timely allocation of staff to the target sensitive areas to improve the safety of the target sensitive areas.

[0055] The technical solution of this embodiment obtains a target longitude and latitude set corresponding to the target sensitive area, and uses the geospatial library to construct a target geospatial image corresponding to the target sensitive area according to the target longitude and latitude set; determines the buffer area corresponding to the target sensitive area according to the target geospatial image and the set proximity distance; obtains a buffer latitude and longitude set corresponding to the buffer area, and generates a buffer geospatial image corresponding to the buffer area according to the buffer latitude and longitude set; obtains the actual longitude and latitude corresponding to each monitored object in the preset monitoring area, and the buffer longitude and latitude of each point on the buffer geospatial image, and determines whether to send a warning information of the monitored object approaching the target sensitive area to the user based on the comparison result of the actual longitude and latitude and each buffer longitude and latitude. The technical means solves the problem that the method of only identifying the visiting personnel at the entrance easily leads to the inability to timely increase the staff for identity verification when there are many visiting personnel, which greatly increases the possibility of unrelated personnel entering the sensitive area. It can realize timely warning of the situation where the monitored object is approaching the sensitive area, thereby improving the security of the sensitive area.

[0056] To illustrate the technical solution of this embodiment in detail, the following is an example of the code used to implement the technical solution of this embodiment:

[0057]

[0058]

[0059] The advantage of this setting is that through the geospatial library, a large amount of geographic data can be quickly processed and it can be accurately determined whether each monitored object is close to the target sensitive area.

[0060] Embodiment 2

[0061] Figure 2 It is a flowchart of another sensitive area proximity warning method provided according to the second embodiment of the present invention. This embodiment is based on the further optimization and expansion of the above embodiments and can be combined with various optional technical solutions in the above implementation methods.

[0062] like Figure 2 As shown, a sensitive area approaching warning method disclosed in this embodiment includes:

[0063] S210, obtaining a target longitude and latitude set corresponding to the target sensitive area, and using a geospatial library to construct a target geospatial image corresponding to the target sensitive area according to the target longitude and latitude set.

[0064] S220: Determine a buffer area corresponding to the target sensitive area according to the target geographic space image and the set proximity distance.

[0065] S230, obtaining a buffer zone longitude and latitude set corresponding to the buffer area, and determining the height value corresponding to each longitude and latitude data in the buffer zone longitude and latitude set according to the height value corresponding to the target sensitive area and the set ratio value.

[0066] In this step, specifically, the height value of the target sensitive area can be multiplied by the set ratio value, and the multiplication result can be used as the height value corresponding to each longitude and latitude data in the buffer longitude and latitude set. Alternatively, the height value corresponding to each longitude and latitude data in the buffer longitude and latitude set can be determined according to the height value corresponding to the target sensitive area, the set ratio value and user needs.

[0067] S240, generating a buffer geospatial image corresponding to the buffer area according to the buffer latitude and longitude set and the altitude value corresponding to each longitude and latitude data in the buffer latitude and longitude set.

[0068] In this embodiment, the buffered geospatial image is a three-dimensional image.

[0069] In this step, specifically, a preset 3D library (such as plotly) can be used to generate a buffer geospatial image corresponding to the buffer area based on the buffer latitude and longitude set and the height value corresponding to each longitude and longitude data in the buffer latitude and longitude set.

[0070] S250, obtaining the actual longitude and latitude corresponding to each monitoring object in the preset monitoring area, the buffered longitude and latitude of each point on the buffered geographic space image, the actual height value corresponding to the actual longitude and latitude, and the buffered height value corresponding to each buffered longitude and latitude.

[0071] S260: Determine whether to send a warning message to the user that the monitored object is approaching a target sensitive area based on the comparison result between the actual longitude and latitude and the buffer longitude and latitude, and the comparison result between the actual altitude and the buffer altitude.

[0072] In this step, specifically, when it is determined that the actual longitude and latitude are equal to any buffer longitude and latitude within an error range, it can be determined whether to send a warning message to the user that the monitored object is approaching a target sensitive area based on the comparison result between the actual height value and each buffer height value.

[0073] Optionally, based on the comparison results of the actual longitude and latitude with each buffer longitude and latitude, and the comparison results of the actual height value with each buffer height value, it is determined whether to send a warning message to the user that the monitored object is approaching the target sensitive area, including: determining the actual array corresponding to the actual longitude and latitude, and selecting one from each buffer longitude and latitude in turn as the current buffer longitude and latitude; determining the current buffer array corresponding to the current buffer longitude and latitude, and using the actual array, the current buffer array, the preset relative tolerance and the preset absolute tolerance as parameters of the preset data comparison function to determine whether the actual longitude and latitude are approximately equal to the current buffer longitude and latitude; if so, obtaining the actual height value corresponding to the actual longitude and latitude, and the current buffer height value corresponding to the current buffer longitude and latitude, and sending a warning message to the user that the monitored object is approaching the target sensitive area when the actual height value is less than or equal to the current buffer height value; if not, returning to execute the step of selecting one from each buffer longitude and latitude in turn as the current buffer longitude and latitude, until the actual longitude and latitude are approximately equal to the current buffer longitude and latitude, or the processing of the buffer longitude and latitude of all points on the buffered geographic space image is completed.

[0074] There may be multiple preset data comparison functions, such as numpy.isclose().

[0075] Exemplarily, the actual array, the current buffer array, the preset relative tolerance, and the preset absolute tolerance may be used as parameters of numpy.isclose() to determine whether the actual longitude and latitude are approximately equal to the current buffer longitude and latitude.

[0076] The advantage of this setting is that when the height of the buffer area is lower than the preset monitoring area, for example, the preset monitoring area is a five-story office building and the buffer area is the first and second floors of the office building, by comparing the actual longitude and latitude with the longitude and latitude of each buffer, as well as comparing the actual height value with the buffer height values, it is determined whether to send a warning information to the user that the monitored object is approaching the target sensitive area, thereby avoiding excessive issuance of warning information and improving the user experience.

[0077] The technical solution of this embodiment generates a buffer geospatial image corresponding to the buffer area through a buffer longitude and latitude set, and the altitude value corresponding to each longitude and latitude data in the buffer longitude and longitude set, and when it is determined that the actual longitude and latitude are equal to any buffer longitude and latitude within the error range, it is further determined whether to send a warning information about the monitored object approaching the target sensitive area to the user based on the comparison result between the actual altitude value and each buffer altitude value, which can improve the accuracy of the warning information sent to the user and enhance the user satisfaction.

[0078] Based on the above embodiments, in order to explain in detail the sensitive area proximity warning method and effect in the present invention, the following is a most detailed embodiment for explanation: Step 1, obtain the target longitude and latitude set corresponding to the target sensitive area, and use the geospatial library to construct the target geospatial image corresponding to the target sensitive area according to the target longitude and latitude set. Step 2, determine the first buffer area corresponding to the target sensitive area according to the target geospatial image and the first preset proximity distance; determine the first buffer area to be processed corresponding to the target sensitive area according to the target geospatial image and the second preset proximity distance, and process the first buffer area to be processed according to the first buffer area to obtain the second buffer area; wherein the first buffer area to be processed includes the first buffer area and the second buffer area; determine the second buffer area to be processed corresponding to the target sensitive area according to the target geospatial library and the third preset proximity distance, and process the second buffer area to be processed according to the first buffer area to obtain the third buffer area; wherein the second buffer area to be processed includes the first buffer area to be processed and the third buffer area.

[0079] Step 3: Determine the height value corresponding to each buffer area according to the height value corresponding to the target sensitive area and the set ratio value. Step 4: Generate a first buffer geospatial image corresponding to the first buffer area according to the first buffer latitude and longitude set corresponding to the first buffer area and the height value corresponding to each buffer area. Generate a second buffer geospatial image corresponding to the second buffer area according to the second buffer latitude and longitude set corresponding to the second buffer area and the height value corresponding to each buffer area. Generate a third buffer geospatial image corresponding to the third buffer area according to the third buffer latitude and longitude set corresponding to the third buffer area and the height value corresponding to each buffer area.

[0080] Step 5: Obtain the actual longitude and latitude corresponding to each monitored object in the preset monitoring area, and the actual altitude value corresponding to the actual longitude and latitude. If the actual longitude and latitude are equal to the first buffer longitude and latitude of any point on the first buffer geospatial image within the error range, and the actual altitude value is less than or equal to the first buffer altitude value corresponding to the first buffer longitude and latitude, an emergency warning message is sent to the user that the monitored object is close to the target sensitive area.

[0081] If the actual longitude and latitude are equal to the second buffer longitude and latitude of any point on the second buffer geospatial image within the error range, and the actual height value is less than or equal to the second buffer height value corresponding to the second buffer longitude and latitude, then the important warning information of the monitored object approaching the target sensitive area is sent to the user. If the actual longitude and latitude are equal to the third buffer longitude and latitude of any point on the third buffer geospatial image within the error range, and the actual height value is less than or equal to the third buffer height value corresponding to the third buffer longitude and latitude, then the general warning information of the monitored object approaching the target sensitive area is sent to the user.
