For convenience of explanation, the following description will be given taking the main execution body of the method as an example of a server.
Referring to fig. 1, the process schematic of the method comprises the following steps:
In embodiment 1 of the present invention, at least two target track coordinates may be obtained by the following method:

The first terminal device can be arranged on the body of a user, and at least two to-be-determined track coordinates are acquired by the first terminal device. The first terminal device is not the execution subject of the method, i.e. is not a server. The first terminal equipment has a positioning function and can acquire the track coordinates of the user.
The at least two to-be-determined track coordinates may be acquired by the first terminal device at preset time intervals. The preset time interval can be any time interval, such as 10 minutes or 1 hour, and can be set according to actual requirements. In addition, each of the at least two to-be-determined trajectory coordinates may be a trajectory coordinate corresponding to a certain position acquired by the first terminal device when it is determined that the duration of the user waiting at the certain position exceeds a preset duration. The preset time period can be any time period, such as 10 minutes, 1 hour or 2 hours, and the equipment can be carried out according to actual requirements.
The number of the at least one preset time period may be any number not less than 1, such as 1, 2, or 3, and may be set according to actual requirements. Any preset time period can be a time period preset by a user, such as 8:00 in 5/month and 3/day in 2018-23: 00 in 5/month and 3/month and 2018. If the number of the at least one preset time period is greater than 1, the at least one preset time period is different time periods, and the condition of time overlapping does not exist in different preset time periods. For example, if the number of the at least one preset time period is 2, the at least one preset time period may be: 3/8: 00-2018/5/3/23: 00, and 5/4/8: 8-2018/5/4/23: 00. It should be noted that the at least one preset time period may be a time period in a working day, and may also be any time period, which is not limited in this respect.
(2) And judging whether the first number of the received track coordinates to be judged in the preset time period is greater than a first preset number or not according to each preset time period.
The first preset number may be any number, such as 1, 2, or 10, and may be set according to actual requirements.
(3) And if the first number is larger than the first preset number, determining the track coordinate to be judged received in the preset time period as the target track coordinate.
It should be noted that, if it is determined that the first number is not greater than the first preset number, deleting the to-be-determined track coordinates received within the preset time period, then receiving at least two to-be-determined track coordinates sent by the first terminal device within a new preset time period, determining whether the first number of the to-be-determined track coordinates received within the new preset time period is greater than the first preset number, if it is determined that the first number is greater than the first preset number, determining the to-be-determined track coordinates received within the new preset time period as target track coordinates, otherwise, performing an operation of receiving at least two to-be-determined track coordinates sent by the first terminal device within another new preset time period.
And 102, generating at least one electronic fence range according to the at least two target track coordinates.
In embodiment 1 of the present invention, at least one electronic fence range may be generated according to at least two target track coordinates by the following three methods:
first, a first method
(1) And judging whether a first target track coordinate exists or not according to each target track coordinate, wherein the first target track coordinate refers to the target track coordinates which are less than a preset distance from the target track coordinate and more than a second preset number.
The preset distance may be any distance, such as 1 meter, 2m, or 100m, and may be set according to actual requirements.
The second preset number may be any number, such as 1, 2, or 3, and may be set according to actual requirements.
The area where the target track coordinate and the first target track coordinate are located may be regarded as an area where the user activity is relatively dense, and the preset distance may be set to be smaller, for example, smaller than 50m or 40 m.
Specifically, it may be determined whether there is a target track coordinate whose distance from the target track coordinate is smaller than a preset distance, and if it is determined that there is a target track coordinate whose distance from the target track coordinate is smaller than the preset distance, it is determined whether the number of target track coordinates whose distance from the target track coordinate is smaller than the preset distance is greater than a second preset number, and if it is determined that the number of target track coordinates whose distance from the target track coordinate is smaller than the preset distance is greater than the second preset number, it is determined that there is a target track coordinate whose distance from the target track coordinate is smaller than the preset distance is a first target track coordinate, and if it is determined that there is no target track coordinate whose distance from the target track coordinate is smaller than the preset distance, it is ignored.
(2) If the judgment result is yes, determining the target track coordinate and a first circle center coordinate corresponding to the first target track coordinate according to the target track coordinate and the first target track coordinate.
And if the judgment result is negative, ignoring the target track coordinate.

(3) And taking the first circle center coordinate as a circle center coordinate, taking the first preset length as a radius to make a circle to obtain a target circle, and taking the range corresponding to the target circle as an electronic fence range.
The first preset radius length may be any length, and preferably may be 800 m.
The determined range of the electronic fence can be regarded as the range of an area with more intensive user activities.
In embodiment 1 of the present invention, by determining whether or not a first target track coordinate exists for each target track coordinate, wherein, the first target track coordinate is the target track coordinate whose distance from the target track coordinate is less than the preset distance and whose number is greater than the second preset number, if the judgment result is yes, determining the target track coordinate and a first circle center coordinate corresponding to the first target track coordinate according to the target track coordinate and the first target track coordinate, using the first circle center coordinate as the circle center coordinate, using the first preset length as the radius to make a circle to obtain a target circle, using the corresponding range of the target circle as the range of the electronic fence, the method can determine the range of the region with the denser user activity range to a certain extent, and the range of the region with the denser user activity range is used as the range of the electronic fence, so that the accuracy of the method for generating the range of the electronic fence is improved.
Second, second method
(1) And acquiring the time length corresponding to each target track coordinate, wherein the time length corresponding to the target track coordinate refers to the time length of the user at the position corresponding to the target track coordinate.
The first terminal can send the acquired track coordinates to the server and can also send the duration to the server at the same time, so that the server can acquire the duration.
(2) And judging whether the time length is greater than a preset time length.
The preset time period can be any time period, such as 1 hour, 2 hours or 3 hours, and can be set according to actual requirements.
(3) If the judgment result is yes, the target track coordinate is taken as a circle center coordinate, a circle is made by taking a second preset length as a radius, a target circle is obtained, and the range corresponding to the target circle is taken as an electronic fence range.
And if the judgment result is negative, ignoring the target track coordinate.
The second preset length can be any preset length and can be set according to actual requirements. The second preset length may be the same as or different from the first preset length.
The determined range of the electronic fence can be regarded as the range of frequent activities of the user.
In embodiment 1 of the present invention, a duration corresponding to each target track coordinate is obtained by referring to each target track coordinate, where the duration corresponding to the target track coordinate is a duration to be waited by a user at a position corresponding to the target track coordinate, and it is determined whether the duration is greater than a preset duration, if the determination result is yes, the target track coordinate is taken as a center coordinate, a circle is made with a second preset length as a radius, a target circle is obtained, a range corresponding to the target circle is taken as an electronic fence range, where a range in which the user frequently moves can be determined to a certain extent, and the range is taken as the electronic fence range, so that accuracy of the electronic fence range generation method is improved.
Third, third method
(1) At least one circle is generated according to the at least two target track coordinates.
Specifically, in at least two target track coordinates, any one target track coordinate is taken as a center coordinate, a fourth preset length is taken as a radius to make a circle, so as to obtain a current circle to be judged, whether at least one target track coordinate does not exist in the current circle to be judged is judged, and if the judgment result is negative, the obtained current circle to be judged is determined as at least one circle generated according to the at least two target track coordinates; if the judgment result is yes, any target track coordinate which does not exist in the current circle to be judged is taken as a circle center coordinate, a fourth preset length is taken as a radius to make a circle, the current circle to be judged is obtained, the operation of judging whether at least one target track coordinate does not exist in the current circle to be judged is executed, and all the current circles to be judged are determined to be at least one circle generated according to at least two target track coordinates.
For example, if the number of at least two target track coordinates is 10, the 10 target track coordinates are numbered 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 in sequence. Randomly selecting the coordinate 1 as a center coordinate, rounding by taking a fourth preset length as a radius to obtain a circle 1, then, determining whether any coordinate in the coordinates 2-10 does not exist in the circle 1, if so, determining the coordinate not existing in the circle 1, for example, if the coordinate not existing in the circle 1 is the coordinates 2-6, randomly selecting a coordinate 3 as a center coordinate from the coordinates 2-6, rounding by taking a fourth preset length as a radius to obtain a circle 3, judging whether any coordinate in the coordinates 2, 4, 5 and 6 does not exist in the circle 3, if so, determining the coordinate not existing in the circle 3, for example, if the coordinate not existing in the circle 2 is the coordinate 2, then, the circle 2 is obtained by making a circle with the circle 2 as the center and the fourth length as the radius, and then the circles 1, 2 and 3 are at least one circle generated according to the at least two target track coordinates.
The fourth preset length may be any length, and the first preset length, the second preset length, and the fourth preset length may be the same, may also be completely different, or may not be completely the same, which is not limited in any way in embodiment 1 of the present invention.

The third preset number may be any number, such as 10, 15, 20, etc., and will not be described herein.
In the prior art, the range of the electronic fence needs to be manually set, but the setting process is complicated, which may cause setting errors for a user, whereas in embodiment 1 of the present invention, the larger the number of circles intersecting the current circle to be analyzed is, the more target track coordinates included in the current circle to be analyzed and the circle intersecting the current circle to be analyzed are, which is a place where the user often goes. The range of the obtained circle is a place frequently visited by the user based on all target track coordinates included in the circles, and the range of the obtained circle is used as the range of the electronic fence, so that the accuracy of the method for generating the range of the electronic fence is improved to a certain extent.

Example 2
Embodiment 2 of the present invention provides a specific method for generating an electronic fence range, where the method is executed in a server, and a first terminal device may be an electronic badge worn by a user, and the electronic badge may implement various functions of the first terminal device mentioned in embodiment 1. The specific electronic fence range generation method is applied to a children anti-lost scene.
The flow diagram of the method can be seen in fig. 2, and the method comprises the following steps:
in step 201, the server obtains at least 30 target track coordinates.
The at least 30 target track coordinates acquired by the server are target track coordinates in 3 working days, and the number of the acquired target track coordinates in each working day is not less than 10.
The badge can collect the track coordinates of the child according to a preset time interval and send the track coordinates to the server. After receiving the track coordinates, the server judges whether the current time is a working day, if so, the server determines the current date and stores the track coordinates in a file corresponding to the current date; if the judgment result is negative, deleting the track coordinate. When the preset end time corresponding to the current date is reached, the server judges whether the number of the track coordinates stored in the file corresponding to the current date is not less than 10, and if the judgment result is yes, the track coordinates are stored in the file; otherwise, the file is deleted. And repeating the steps until the 3 files are obtained, then not receiving the track coordinates sent by the electronic badge, and reading all the track coordinates in the 3 files into a set C. The track coordinates in set C may be considered target track coordinates.
Wherein, the set C can be represented as: c ((x1, y1), (x2, y2), (x3, y3), … … (xn, yn)), wherein n is an integer of 30 or more.
For a specific implementation manner of step 202, reference may be made to the manner mentioned in embodiment 1, which is not described herein again, and the fourth preset length may be 800 m.
For example, a circle 1 is formed with (x1, y1) as the center and 800m as the radius, a corresponding circle set 1 is created for the circle 1, whether (x2, y2), (x3, y3) … … (xn, yn) is within the circle 1 is determined, the track coordinates existing within the circle 1 are stored in the circle set 1, and the track coordinates not existing within the circle 1 are stored in the set D.
Each set of circles may be numbered, for example, for circle set 1, the set of circles that intersects circle set 1 is determined, and the intersecting sets of circles are recorded. And if the distance between the circle center coordinates corresponding to the two circle sets is smaller than the diameter 1600m, the two circle sets are considered to be intersected. The intersection of the set of circles described here corresponds to the intersection of the circles mentioned in example 1. Whether the two circles intersect can be judged in other manners, which is the prior art and is not described herein again.
For example, fig. 3 is an image in which the respective circles intersect, and fig. 3 includes 9 circles, which are circle 1 to circle 9, circles intersecting circle 1 are circle 2, circle 3, circle 4, and circle 5, circles intersecting circle 2 are circle 1, circle 6, and circle 9, circles intersecting circle 3 are circle 1 and circle 4, circles intersecting circle 4 are circle 1, circle 3, and circle 5, circles intersecting circle 5 are circle 1 and circle 4, circles intersecting circle 6 are circle 2 and circle 9, respectively, and circles not intersecting circle 7 and circle 8, and circles intersecting circle 9 are circle 2 and circle 6, respectively.
Wherein, the number of the circle sets intersected with the circle set 1 is the largest and is 4, and at least one electronic fence range is generated according to the circle sets 1-5. And then, determining an intersected circle set in the remaining circle sets 6, 7, 8 and 9, wherein the circle set 6 is intersected with the circle set 9, generating at least one electronic fence range according to the circle set 6 and the circle set 9, and the circle set 7 and the circle set 8 do not have intersected circle sets, and respectively generating corresponding electronic fence ranges according to the circle set 7 and the circle set 8. For a method for determining the range of the electronic fence according to each circle set, which is equivalent to the method for determining the range of the electronic fence according to each circle, reference may be made to the method for generating at least one range of the electronic fence according to at least two target track coordinates mentioned in embodiment 1, which is not described herein again.
And step 206, the server acquires the action track of the child in real time, sends a message that the child leaves the range of the electronic fence to the mobile phone when the action track of the child moves from any electronic fence range to any electronic fence range, and sends a message that the user enters the range of the electronic fence to the mobile phone when the action track of the child moves from any electronic fence range to any electronic fence range.
And step 207, receiving and displaying a message that the child leaves the range of the electronic fence by the mobile phone, or receiving and displaying a message that the child enters the range of the electronic fence.
The mobile phone is equivalent to the second terminal device mentioned in embodiment 1, and parents can carry the mobile phone with them to monitor the moving track of the child in real time and see whether the moving track is in the range of the electronic fence, so as to know whether the child is safe.
