Preferred embodiment of the invention

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

In order to monitor the security situation of the user and improve the user experience in time, according to an aspect of the present invention, a method for monitoring a geographical location is provided, which is applied to a geographic location monitoring device. In this context, the geographic location monitoring device can be a mobile terminal, a smart bracelet, a smart watch, or any device known in the art or possible to be able to locate itself. It can be understood that the geographic location monitoring device generally moves with the movement of the user carrying the geographic location monitoring device, so the user moves synchronously with the geographic location monitoring device, and the geographic location of the user is the geographic location monitoring device. The location of the preparation.

FIG. 1 shows a schematic flow diagram of a method of geographic location monitoring 100 in accordance with one embodiment of the present invention. As shown in FIG. 1, the geographic location monitoring method 100 includes step S110, step S130, step S150, and step S170.

In step S110, the current time is determined, for example, it is determined that the current time is 9:10 am.

Determining the current time can monitor the system clock of the device based on the geographic location. Alternatively, the geolocation monitoring device can be connected to the network, and the geolocation monitoring device can synchronize its system clock based on the network clock through the network. For example, the geolocation monitoring device can automatically update its system clock periodically. Alternatively, the geolocation monitoring device can also update its system clock based on the received update instructions.

In step S130, the geographic location of the geographic location monitoring device is determined. Determining the geographic location of the geographic location monitoring device, that is, locating the geographic location monitoring device, may employ any suitable positioning method, such as base station positioning, wireless fidelity (Wi-Fi) positioning, or satellite positioning.

When the geolocation monitoring device has a mobile communication module, such as a Global System for Mobile Communications (GSM) module, it can detect surrounding base station information through the mobile communication module. Subsequently, the geolocation monitoring device can utilize the detected base station information for positioning. For example, the geographic location monitoring device can measure the downlink pilot signals of different base stations and obtain the Time of Arrival (TOA) or Time Difference of Arrival (TDOA) of the downlink pilot signals of different base stations. Based on the measurement result and in combination with the coordinates of the base station, for example, using a triangular formula estimation algorithm, the geographic location of the geographic location monitoring device can be calculated. The method for determining the geographical location of the geographic location monitoring device by using the base station information has low power consumption, high efficiency, and easy implementation.

When the geolocation monitoring device has a Wi-Fi module, it can utilize Wi-Fi access information for positioning. For example, when the geographic location monitoring device turns on the Wi-Fi function, when it is ready to access the Internet through a Wi-Fi hotspot (ie, a Wi-Fi access point, referred to as an AP), it searches for and collects surrounding AP signals, and generates and includes Wi-Fi access information of AP identifier and AP signal strength information. The geographic location monitoring device can obtain the geographic location of each AP according to the AP identifier, and determine the geographic location of the geographic location monitoring device according to the strength of each AP signal. The method for determining the geographical location of the geographic location monitoring device through the Wi-Fi access information has higher positioning accuracy and lower power consumption.

When the geographic location monitoring device has a satellite positioning module, such as a Global Positioning System (GPS) module, the geographic location monitoring device can utilize the detected satellite information for positioning. By satellite The method of determining the geographic location of the geographic location monitoring device can obtain a highly accurate positioning result.

In addition, some indoor positioning techniques can also be utilized to determine the geographic location of the geographic location monitoring device while indoors. For example, the geographic location monitoring device may have a radio frequency identification (RFID) module, and in addition, an RFID tag may be installed in each of a bedroom, a kitchen, a bathroom, and the like. In this way, the geolocation monitoring device can identify which room it is located by using the RFID tag.

In step S150, it is determined whether the current time is included in a specific time period involved in the security area map.

The security zone is the zone in which the user of the geo-monitoring device is considered to be in a safe state if it is in the zone. The security zone map contains information about the security zone for a specific time period. People's daily activities are usually regular. For example, students go to school and leave school at a fixed time, and office workers go to work and get off work at a fixed time. Therefore, the geographical location of most people in a day is also regular. The security zone map shows information about the secure geographic location over a specific time period.

The particular time period can be a specific time period of the day. Additionally, the particular time period can include a plurality of small time periods.

2 shows a schematic diagram of a security zone map in accordance with one embodiment of the present invention. Figure 2 can be drawn based on a common map. Figure 2 shows a flat map of an area, for the sake of brevity, detailed map data for that area is not shown. In Figure 2, the shaded area is a safe area. The dashed line is the time axis, which identifies the time information. It can be understood that the length corresponding to the unit time period may be different on the time axis, for example, the length corresponding to the time from 9:00 to 9:10 is longer than the length corresponding to the time 9:10 to the time 9:20. . The length corresponding to the unit time period is related to the moving speed of the geographical position monitoring device. If the movement speed is faster, the length corresponding to the unit time period will be longer. If the movement speed is slower, the length corresponding to the unit time period will be shorter. As shown in FIG. 2, the security zone map includes security zone information for a time period between 8:57 and 10:05 am. In a practical example, the time axis may be along a road that the user is passing through.

In step S170, if the current time is included in the specific time period involved in the security area map, it is determined whether the geographical location is located in the security area based on the security area map.

First, it is determined whether the current time is included in a specific time period involved in the security area map. For example, the current time is 9:07, then the current time is included between 8:57 and 10:05 as shown in Figure 2. Within the time period.

Then, if the current time is included in the specific time period involved in the security area map, it is determined whether the currently determined geographical location is located in the security area based on the security area map. On the safety area map shown in Fig. 2, the vertical line of the time axis is drawn at the current time. Determining whether the currently determined geographic location is within the secure area based on the currently determined geographic location and the relative location of the secure area on the vertical line. As shown in FIG. 2, the geographic location A in FIG. 2 is located in the security zone, and the geographic location B is not located in the security zone.

When the geographic location monitoring device is in a secure area, the user of the geographic location monitoring device may be in a safe state. When the location monitoring device is outside the security zone, the user of the geolocation monitoring device may be in an unsecured state. For example, suppose the location monitoring device is a smart bracelet and its users are students. For the student, it is normally located at school from 8 am to 5 pm, Monday through Friday. If at 10 am on a Monday, the location of the detected location monitoring device is far from the safe area near the school, the child may be considered to be in an unsafe state.

According to the geographic location monitoring method provided by the present invention, whether the geographic location monitoring device is in the security zone is determined by the security zone map, and the security situation of the user of the geographic location monitoring device can be known in time to achieve the purpose of securing the security of the user.

Optionally, before step S150, the foregoing method 100 may further include step S140: obtaining a security area map. The obtaining a security zone map can include generating a security zone map. Alternatively, the obtaining the security zone map may further comprise obtaining the security zone map directly from the memory.

FIG. 3 shows a schematic flow chart of obtaining a security area map in step S140 according to an embodiment of the present invention. As shown in FIG. 3, the step S140 specifically includes step S141, step S142, and step S143.

In step S141, the training geographic location of the geographic location monitoring device is acquired during a specific time period of the plurality of time periods.

Alternatively, the time period can be one day, that is, 24 hours. As mentioned above, people's activities are usually in a time period of one day. Go to work or school in the morning, go to lunch at noon, get off work or school in the evening, and sleep at home in the evening. So the daily activities are more regular. Generate a security zone map based on daily activities and determine if the geolocation monitoring device is in a secure zone based on the security zone map More reasonable, can get more ideal results.

In this step, the training geographic location of the geographic location monitoring device is acquired during the same specific time period of each time period. For example, the training geographic location of the geographic location monitoring device can be collected for a period of 30 consecutive days from 6:00 am to 22:00 pm. 4 shows a schematic diagram of a captured partial training geographic location in accordance with one embodiment of the present invention. Among them, the black triangle in FIG. 4 shows the training geographic location collected at 9:00 am, and the open triangle shows the training geographic location collected at 9:10 am.

It can be understood that the acquisition operation may be based on a specific frequency during the specific time period. For example, it is collected every 10 minutes. Alternatively, the frequency of the acquisition operation may also be based on the motion of the geographic location monitoring device, for example, when the geographic location monitoring device moves faster, the frequency of the acquisition operation may be higher. When the geolocation monitoring device moves at a slower speed, the frequency of the acquisition operation can be lower.

In step S142, a security zone of a specific time period is determined according to the training geographic location. As described above, the activity of the user of the geographic location monitoring device is usually regular, and the training geographic location is collected in multiple time periods, so the training geographic location and the corresponding collection time information reflect the geographical location monitoring to some extent. The movement track of the device. In general, if a user goes to a particular geographic location at a particular moment each day, the particular geographic location can be considered safe. If a user has never been to a particular geographic location at a particular moment, that particular geographic location is likely to be dangerous. Therefore, the security zone of a specific time period can be determined according to the collected training geographic location.

In step S143, a security area map is generated according to the security area of the specific time period. A safe area map can be generated by synthesizing the determined safety zone. The security zone map includes information about the security zone for a specific time period.

In the above example, the user's previous life trajectory of the location monitoring device is used to generate his or her own security zone map, which is more targeted. In addition, using the training geographic location collected over multiple time periods to generate the safe area map, the result is more accurate. Thus, the security status of the geographic location determined according to the security zone map is more reasonable.

Optionally, the foregoing step S142 determines the security area of the specific time period according to the training geographic location, and specifically includes the following steps A and B.

In step A, the training geographic locations collected according to multiple moments in a specific time period are respectively Determine the security zone for the multiple moments. The training geographic location and its acquisition time information together determine the action trajectory of the user of the geographic location detecting device. For each acquisition time, multiple training geographic locations are acquired for multiple time periods. In the schematic diagram of the training geographic location shown in FIG. 4, the black triangle and the open triangle are the training geographic locations collected at 9:00 am and 9:10 am in 30 cycles, respectively.

Optionally, step A specifically includes performing the following operations for each of the plurality of periods:

First, determine the center of the training geographic location collected at each moment. Fig. 5 is a view showing a part of the safety zone map shown in Fig. 2 described above. As shown in Figure 5, the black triangle is the training geographic location acquired at 9:00 AM in 30 cycles. Determine the geometric center of these training locations, as shown in center C of Figure 5. Similar to the center C, the center D is the center of the training geographic location collected at 9:10 am in the 30 cycles indicated by the open triangle.

Then, determine the radius of the safe area corresponding to the moment.

Optionally, the radius of the security area corresponding to the moment is determined according to the type of the training geographic location collected at the moment. Some locations may be safer around, such as at home or near school. In such a geographical location, the radius of the safe area can be set larger. Some geographical locations may be less secure, such as subway stations and other transportation hubs, shopping malls and other public places. In such a geographic location, the radius of the security zone can be set smaller. Thus, the security near the training geographic location can be determined according to the type of the training geographic location, and then the radius of the security region corresponding to the time is determined.

Determining the radius of the security area according to the type of the training geographical location, and determining the size of the security area can make the determined security area more reasonable, and ensuring that the user of the geographic monitoring device is in a safe state within the security area.

Alternatively, the radius of the security area corresponding to the moment may be determined according to the probability distribution of the training geographic location collected at the moment. Specifically, the distance between all of the training geographic locations collected at that time and the centers of the training geographic locations can be calculated. The mean μ and the variance σ of these distances are calculated, and then the radius of the safe area corresponding to the moment is determined according to the mean μ and the variance σ according to the user's request. For example, if the user request is loose, then μ+2*σ can be used as the radius of the safe area. Because the training geographic location with a distance greater than μ+2*σ from the center is approximately 2.2%. It can be understood that the radius of the safe area can also be μ, μ+σ, μ+3*σ, and the like.

The radius of the safe area is determined according to the probability distribution of the training geographical location, and then the size of the safe area is determined according to the past behavior track of the user, and the determined safe area is more accurate.

Finally, a circular area centered on the center and radiused by the radius of the safe area is determined as the safe area at that moment. Thereby, a safe area for each acquisition time of the training geographical location in a specific time period is determined. As shown in the two circular areas in Figure 5.

The use of a circular area to determine the security area at each moment takes into account the fault tolerance of the security area and does not cause too many false positives for the geo-monitoring device not in the security area. Moreover, the scheme is easy to implement and the amount of calculation is small.

It will be appreciated that other shapes may also be used to determine the security zone at each moment based on various considerations.

In step B, a security zone of a specific time period is determined according to the security zone of the plurality of times. The security area of the plurality of moments generally depicts the action trajectory of the user of the geographic location monitoring device, and it is reasonable to determine the security zone for the specific time period based on the security zone of the plurality of times. For example, in the example where the security area determined at each of the above moments is a circular area, two public tangent lines of two circles may be used as the boundary of the security area. As shown in Figure 5, the circular safety zones at two adjacent moments and their common tangent lines together define a safe zone for that particular time period, as shown by the shaded portion.

Optionally, the step B specifically includes: determining a security area of a time period between adjacent moments according to a distance between centers of the security areas at adjacent moments. For example, if the distance between the two centers is greater than the distance threshold, for example, 50 meters, then in the time period between the adjacent moments, only the security areas of two adjacent moments are safe areas, and other areas are not safe areas. . 6 shows a schematic diagram of a portion of a security zone map in accordance with another embodiment of the present invention. As shown in Figure 6, the distance d between the centers of the two circular security zones is greater than the distance threshold, so there will be no security zone between the two circular security zones.

If two adjacent centers are too far apart, there may be a potential hazard based only on the safety zones at two adjacent moments. For example, the user of the geo-monitoring device is out of the safe area between these two points, and is in an unsafe state, and the geo-detection device fails to find it in time. Determining the safe area of the time period between adjacent moments based on the distance between the two avoids this potential hazard.

It is easy to implement a safe area including a plurality of time points for a specific time period, and the operability is strong.

Optionally, determining the geographic location based on the security area map in step S170 of the foregoing method 100 is After being located within the secure area, method 100 further includes step S190 (not shown), and if it is determined that the geographic location is outside of the secure area, an alert operation is performed.

If the location monitoring device is outside the security zone, it indicates that the user of the geolocation monitoring device is likely to be in an unsecured state at this time, and the surrounding person or associated user can be notified in time by performing an alarm operation, so that geography can be guaranteed as much as possible. The safety of the user of the location monitoring device.

Optionally, performing the alarm operation described above may include issuing a warning message, for example, the geographic location monitoring device may include a buzzer and/or an alarm light or the like. The buzzer can beep and the warning light can emit a flashing red light. The beep and flashing red light are warning messages. When the surrounding person hears a beep or sees a flashing red light, it can be known that the user of the geographical location monitoring device is in an unsafe state.

Optionally, the performing the alarm operation may include acquiring the monitoring information; and transmitting the monitoring information to the associated device of the geographic location monitoring device. When the geographic location monitoring device is in an abnormal location state, it can monitor conditions such as the surrounding environment and send monitoring information to the associated device so that the user of the associated device can know. In this way, the user of the associated device can know the situation of the surrounding environment where the geographical location monitoring device is located in time. This helps the user of the associated device to find the user when the user of the geographic location monitoring device is lost. Optionally, the monitoring information includes recording information, recording information, and/or photographing information.
