[0033] Figure 1 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example:

[0036] See also Figure 1 In an embodiment of the present invention, a method for adjusting an electronic fence range includes:

[0037] S1: Set the center point and define the electronic fence area;

[0038] S2: Obtain the prompt information of the boundary of the electronic fence area triggered by the current smart device;

[0039] S3: Determine the source method of the current smart device to obtain the positioning information, adjust the area of ​​the electronic fence area according to the source method of the positioning information, and set the adjusted electronic fence area as the adjustment area, and determine whether to output the position information within the set time according to the source method of the positioning information and the position of the smart device relative to the adjustment area, wherein the position information is the information of the smart device relative to the outside or inside of the electronic fence area;

[0040] S4: Transmit the location information to a receiving end, which is used to receive the location information of the smart device and output a status change reminder of the smart device.

[0041] Specifically, the method is applied to smart devices such as children's smart watches. The smart devices are worn on children's arms and are used to remind children when they are out of range. The method sets a center point and demarcates an electronic fence area, wherein the center point is a residential building or a school teaching building, etc. The electronic fence area is used to monitor whether children and smart devices are within the range. After obtaining the boundary of the electronic fence area triggered by the smart device, a prompt message is issued, the source method of the smart device to obtain the positioning information is judged, and the area of ​​the electronic fence area is adjusted according to the source method. Whether to output the location information in a set time segment, and then whether to send the location information after the smart device triggers the electronic fence area back and forth multiple times within the set time range, so as to facilitate the output of the state change reminder of the smart device at the receiving end, so that after the child triggers the electronic fence area back and forth multiple times and within the set time range, a single reminder is issued at the receiving end, reducing multiple warning reminders at the receiving end, so as to normally judge whether the smart device enters or leaves the electronic fence monitoring area, and the use effect is good, wherein the receiving end is the parent's mobile phone end, and the prompt warning is issued through the parent's mobile phone end.

[0042] Preferably, a center point is set and an electronic fence area is delineated; the electronic fence area is a circular area with the center point as the center, and the radius of the circular area is a first radius, which is used to determine the area of ​​the electronic fence area.

[0043] Furthermore, a circular electronic fence area is defined with a residential building or a school teaching building as the center point and a first radius, and the first radius is recorded as R1 and the electronic fence area is recorded as A1, A1 = πR1 2 The circular electronic area is convenient for area division, which makes the area division operation convenient and easy to operate.

[0044] Preferably, the source mode of the current smart device acquiring the positioning information is determined, and the area of ​​the electronic fence area is adjusted according to the source mode of the positioning information, and the adjusted electronic fence area is set as the adjustment area, and it is determined whether to output the position information within the set time according to the source mode of the positioning information and the position of the smart device relative to the adjustment area;

[0045] The sources of the positioning information include satellite positioning mode, fixed-point positioning mode and conversion from fixed-point positioning mode to satellite positioning mode;

[0046] The smart device obtains positioning information through satellite positioning mode and directly outputs the location information;

[0047] When the smart device switches from the fixed-point positioning mode to the satellite positioning mode to obtain positioning information, it directly outputs the location information;

[0048] The smart device obtains positioning information through the fixed-point positioning mode, adjusts the area of ​​the electronic fence area, and determines whether to output the position information within the set time based on the position of the smart device relative to the adjusted area.

[0049] Specifically, when it is determined that the source mode of the current smart device for obtaining positioning information is the satellite positioning mode, and the satellite positioning mode is the remote positioning mode, it is determined that the smart device has moved away from the set electronic fence range, and the corresponding location information is directly transmitted to the parent's mobile phone, so that the parent's mobile phone can display and remind the child to leave the electronic fence monitoring area;

[0050] When it is determined that the current source mode of the smart device for obtaining positioning information is changed from the fixed-point positioning mode to the satellite positioning mode, and after the fixed-point positioning mode is changed to the satellite positioning mode, that is, the same as the satellite positioning mode, it is determined that the smart device has moved away from the set electronic fence range, and the corresponding location information is directly transmitted to the parent's mobile phone, so that the parent's mobile phone can display and remind the child to leave the electronic fence monitoring area;

[0051] When it is determined that the source mode of the current smart device for obtaining positioning information is the fixed-point positioning mode, the coverage range of the fixed-point positioning mode partially overlaps with the electronic fence A1, that is, the fixed-point positioning mode can monitor the two states of children entering the electronic fence and leaving the electronic range. After determining that the source mode is the fixed-point mode, the area of ​​the electronic fence area is adjusted, and according to the position of the smart device relative to the adjusted area, it is determined whether to output the location information within the set time, and the corresponding location information within the set time is directly transmitted to the parent's mobile phone, so that it is convenient to display and remind the child to enter or leave the electronic fence monitoring area through the parent's mobile phone, so that after the child triggers the electronic fence area back and forth multiple times, and a single reminder is given at the receiving end within the set time range, multiple warning reminders at the receiving end are reduced, so as to normally judge that the smart device enters or leaves the electronic fence monitoring area, and the use effect is good.

[0052] Preferably, the fixed-point positioning mode is a wireless network (Wi fi) positioning mode and a base station positioning mode. The wireless network positioning mode performs positioning according to the wireless network signal and the wireless network access point information in the database, and the base station positioning mode performs positioning according to the signal of the base station;

[0053] The satellite positioning mode is the GPS positioning mode, which performs positioning based on satellite signals.

[0054] Specifically, the wireless network (Wi fi) positioning mode and base station positioning mode are a hybrid positioning technology based on wireless networks and mobile base stations. This technology combines the two methods of WiFi positioning and base station positioning to improve the accuracy and reliability of positioning. WiFi positioning relies on collecting and analyzing the strength of WiFi signals and the WiFi access point (AP) information in the database. The device can scan and record the MAC address and signal strength of the WiFi network around it. This information is sent to the server, which calculates the approximate location of the device through triangulation or other positioning algorithms combined with pre-collected WiFi data. The accuracy of WiFi positioning is usually within the range of 50 meters to 500 meters. Base station positioning uses the signals of mobile communication base stations to achieve positioning. Mobile devices can obtain signals from surrounding base stations, and each base station has a certain coverage range. Through the signals of multiple base stations, it can be determined that the device is roughly located at the intersection of circles with these base stations as the center. Base station positioning usually requires the signals of at least three base stations for positioning, and the accuracy can generally reach 10 to 300 meters in urban environments, but may be worse in suburban or rural areas. WiFi positioning is suitable for indoor environments because WiFi signals can penetrate walls to achieve more accurate indoor positioning. Base station positioning is more suitable for outdoor environments, especially in areas with good signal coverage. Combining WiFi positioning and base station positioning not only improves positioning accuracy, but also increases positioning reliability;

[0055] The working principle of GPS positioning mode mainly relies on a group of satellites distributed in the earth's orbit. These satellites continuously send radio signals containing their precise position, time and correction data to the ground. GPS receivers receive these signals and use the time required for the signal to propagate from the satellite to the receiver multiplied by the propagation speed of electromagnetic waves (i.e. the speed of light) to calculate the distance between the receiver and the satellite.

[0056] Preferably, adjusting the area of ​​the electronic fence area, and determining whether to output the location information within a set time according to the position of the smart device relative to the adjusted area, includes:

[0057] Acquire first positioning information and second positioning information of the smart device within a set time;

[0058] If the first positioning information is located outside the electronic fence area, and the second positioning information is located inside the electronic fence area, the electronic fence area is reduced to an adjustment area, and the radius of the reduced adjustment area is the second radius. If the second positioning information is within the adjustment area, if the set time is less than the preset positioning time, the position information is not output. If the set time is greater than the preset positioning time, the information of the smart device relative to the inside of the electronic fence area is output;

[0059] If the first positioning information is located inside the electronic fence range and the second positioning information is located outside the electronic fence range, the electronic fence area is expanded to the adjustment area, and the radius of the expanded electronic fence area is the third radius. The second positioning information is within the adjustment area. If the set time is less than the preset positioning time, the location information is not output. If the set time is greater than the preset positioning time, the information of the smart device relative to the outside of the electronic fence area is output.

[0060] Specifically, the first positioning time is T1, the second positioning time is T2, the time interval is set to T, the first positioning information of the smart device obtained is P1, and the second positioning information of the smart device obtained is P2;

[0061] If the first positioning information P1 is located outside the electronic fence area A1, and the second positioning information P2 is located inside the electronic fence area A1, the electronic fence area is reduced to the adjustment area A2, and the radius of the reduced adjustment area is the second radius R2. The second positioning information P2 is within the adjustment area A2. If the set time is less than the preset positioning time, the position information is not output, that is, if the child goes back and forth in and out of the electronic fence area A1 multiple times within a period less than the preset positioning time, the position information is not output, that is, the parent's mobile phone will not remind. If the set time is greater than the preset positioning time, the information of the smart device relative to the inner side of the electronic fence area is output. If the child goes back and forth in and out of the electronic fence area A1 multiple times within a period greater than the preset positioning time, the information of the smart device relative to the inner side of the electronic fence area is output, and the parent's mobile phone reminds the child of entering the electronic fence area once, which will not affect the parent's normal judgment.

[0062] If the first positioning information P1 is located inside the electronic fence area A1, and the second positioning information P2 is located outside the electronic fence area A1, the electronic fence area is expanded to the adjustment area A3, and the radius of the expanded electronic fence area is the third radius R3. The second positioning information P2 is within the adjustment area A3. If the set time is less than the preset positioning time, the location information is not output, that is, the parent's mobile phone will not remind you. If the set time is greater than the preset positioning time, the information of the smart device relative to the outside of the electronic fence area is output. When the child goes in and out of the electronic fence area A1 multiple times within a period greater than the preset positioning time, the information of the smart device relative to the outside of the electronic fence area is output, and the parent's mobile phone reminds you of a single entry into the electronic fence area, which will not affect the parent's normal judgment.

[0063] Preferably, the preset positioning time is greater than or equal to five minutes.

[0064] Specifically, if the preset positioning time is greater than or equal to five minutes, different preset positioning times can be set, specifically five minutes, ten minutes, fifteen minutes, etc., and the preset time is used as the limit. After exceeding the preset time, that is, when the time when the child repeatedly enters and exits the electronic fence area A1 exceeds the preset time, the information of the smart device relative to the inside of the electronic fence area is output. The set time length is adjustable, the application range is wide, and the time span is convenient to adjust.

[0065] Preferably, the first radius / second radius range is 1.5-2.5, and the first radius / third radius range is 0.8-0.5.

[0066] Specifically, the first radius / second radius range is 1.5-2.5, the first radius remains unchanged, and the second radius is reduced, wherein the first radius / second radius is 2, that is, R1 is reduced by 50% (ie, R1 / R2=2), and the adjustment area A2 is reduced to determine the information of the smart device relative to the inner side of the electronic fence area;

[0067] The first radius / third radius range is 0.8-0.5, the first radius remains unchanged and the second radius is increased, wherein the first radius / second radius is R1 is expanded by 50% (i.e. ), the adjustment area A2 is enlarged to determine the information of the smart device relative to the outside of the electronic fence area

[0068] Preferably, it also includes a map business mode, which includes several positioning map business modes, compares the positioning accuracy of several positioning map business modes, and sets the positioning map business mode with higher accuracy as the default map business mode of the electronic fence.

[0069] In the map provider mode, the system can automatically monitor and compare the positioning data accuracy provided by various positioning map providers. By comparing the real-time positioning data analysis with the actual location information, the map provider with the highest positioning accuracy is identified and set as the default map provider for the electronic fence. This function not only improves the accuracy and reliability of the electronic fence system, but also provides users with a more stable and efficient positioning service.

[0070] Preferably, when setting the center point, the smart device autonomously searches for a wireless network (Wifi) positioning mode and a base station positioning mode in a fixed-point positioning mode;

[0071] Synchronous acquisition of GPS signals in satellite positioning mode;

[0072] The offset and difference of the positioning information are obtained according to the fixed-point positioning mode and the satellite positioning mode, and the ratios of the first radius / the second radius and the first radius / the third radius are re-proportioned to improve the accuracy of the electronic fence positioning.

[0073] By comparing the offset and difference of the positioning information obtained in the fixed-point positioning mode and the satellite positioning mode, the offset and difference can be identified and corrected to ensure the accuracy of positioning. At the same time, the ratio of the first radius, the second radius and the third radius can be dynamically adjusted according to the positioning information to adapt to different environments and scenarios. This dynamic adjustment capability makes the electronic fence system more flexible and intelligent, and can more effectively protect the safety of users.

[0074] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
