In the traditional positioning technology, when the terminal performs positioning, the positioning module is usually opened at a fixed positioning frequency for positioning. Terminal positioning is to know the location of the user, and it is necessary to ensure a certain positioning accuracy. Since the end user may be in different active states, there is no need to locate as frequently in a state of motion (such as running) when staying for a long time (for example, a classroom), and thus the conventional technology has a fixed positioning frequency with power consumption. Higher disadvantages.

A method and system for adjusting a terminal positioning frequency that can at least solve a high power consumption will be described below. A positioning interval adjustment method and system are also described.

FIG. 1 is a schematic flow chart of a terminal positioning frequency adjustment method according to an embodiment. A terminal positioning frequency adjustment method includes the following steps:

Step S110: Perform positioning according to a known positioning frequency. The known positioning frequency may be the already confirmed positioning frequency. For example, when the method is started, it may be a preset positioning frequency; for example, after the method is started, it may be the positioning frequency confirmed by the previous adjustment round.

Step S120: Read the sensing data of the acceleration sensor. When the sensing data satisfies the preset condition, the process proceeds to step S130. The sensing data of the acceleration sensor can be monitored and read by the monitor, that is, the sensing data of the acceleration sensor is periodically read to monitor the change of the sensing data of the acceleration sensor.

The acceleration sensor may be a three-axis acceleration sensor, and the sensing data of the acceleration sensor may include three axial acceleration data, such as three axial acceleration data of the X-axis, the Y-axis, and the Z-axis. The sensing data of the acceleration sensor may not only be the sensing data at a certain moment, but may include the sensing data for a certain period of time.

The preset condition may include scenario configuration data pre-stored on the local storage medium, and the scenario configuration data is used to determine the motion scenario of the terminal. The scenario configuration data may include three axial acceleration data set in advance, such as three axial acceleration data of the preset X-axis, Y-axis, and Z-axis. When the sensing data sensed by the acceleration sensor satisfies the preset scenario configuration data (for example, it may be in a range), it is determined that the sensing data meets the preset condition.

The scenario configuration data is used to determine a motion scenario of the terminal, such as a motion scenario for determining that the terminal user is stationary, walking, running, jumping. For example, the scenario configuration data includes three axial acceleration data preset, for example, the scenario configuration data includes preset axial acceleration data of the X axis, the Y axis, and the Z axis. Generally speaking, when the user has a certain regular movement such as walking, running, jumping, etc., the acceleration sensor in the terminal will detect the regular induction accordingly. data. Of course, this regular sensing data needs to be combined with the specific application of the terminal. If the terminal is a wearable device (such as a smart bracelet or a smart watch), there will be regular sensing data to characterize the user walking, running, jumping; It is a smart terminal device (such as a smart phone), and there are also other regular sensing data to characterize the user walking, running, jumping.

Therefore, a plurality of sets of scenario configuration data may be set for determining a motion scenario of the terminal, for example, the plurality of sets of scenario configuration data respectively determine the end user's motion scenarios such as stationary, walking, running, jumping, and the like. When the sensing data of the acceleration sensor satisfies one of the scenario configuration data in the scenario configuration data, it may be determined that the terminal user is performing the motion corresponding to the group of scenario configuration data.

Generally, when the end user is doing a rapid transfer movement (for example, walking, running, etc.), since it is necessary to ensure the positioning accuracy, it is necessary to increase the positioning frequency at this time. Therefore, the scenario configuration data can be set to determine that the terminal is doing a fast transfer motion. When the sensing data of the acceleration sensor satisfies the scenario configuration data, it can be determined that the terminal user is performing a fast transition motion, that is, the sensing data meets the preset condition, and step S130 can be performed.

Of course, the scenario configuration data may also be set to determine that the terminal determines that the sensing data meets the preset condition when performing a slow moving motion (such as walking or walking), and the positioning frequency may be adjusted. At this time, when the end user is performing the slow moving motion, the sensing data of the acceleration sensor is sensed, and the positioning frequency can be adjusted, and step S130 is performed.

In some embodiments, the preset condition further includes a first preset condition. When the sensing data satisfies the first preset condition, the positioning is performed once and then the secondary positioning is performed according to the known positioning frequency. This is because if the end user is doing a fast transfer movement, due to the rapid change of position, if there is no immediate positioning, there may be a large position blank during this time. Therefore, the scenario configuration data included in the first preset adjustment may be used to determine that the end user is doing a quick transfer motion, such as running, riding, and the like. Taking the acceleration sensor as an example, when the sensing data sensed by the acceleration sensor satisfies the first preset adjusted scene configuration data (for example, it may be in a range), it is determined that the sensing data satisfies the first preset condition. Step S130: after the sensing data meets the preset condition, according to the increase or decrease of the displacement value of the terminal between the two adjacent positionings relative to the reference displacement value, adjusting the positioning frequency accordingly increases or decreases the positioning frequency relative to the reference positioning frequency. . Can determine the adjacent according to the positioning data of two adjacent positioning The displacement value of the terminal between two positionings. 2 is a schematic flowchart of determining a displacement value of a terminal between adjacent two positionings according to positioning data of two adjacent positioning according to an embodiment, and determining a terminal between two adjacent positioning according to positioning data of two adjacent positionings The process of shifting the value specifically includes the following steps:

Step S210: The driving positioning module performs the first positioning (the first time of the above two adjacent positionings) to obtain the first geographical location data. The first geographic location data may be satellite positioning data, such as GPS positioning data (positioning data including latitude and longitude coordinate data).

Step S220: The driving positioning module performs secondary positioning (the second time of the above two adjacent positionings) according to the known positioning frequency to obtain the second geographical location data. Similarly, the second geographic location data may be satellite positioning data, such as GPS positioning data (positioning data including latitude and longitude coordinate data).

Step S230: Calculate the distance obtained by using the second geographical position data and the coordinate difference value of the first geographical location data as the displacement value of the terminal. For example, if the first geographic location data is (X1, Y1) and the second geographic location data is (X2, Y2), the displacement value of the terminal can be obtained as

Of course, it is also possible to determine the displacement value of the terminal between two adjacent positionings according to the sensing data of the acceleration sensor between two adjacent positioning.

3 is a schematic flow chart of determining a displacement value of a terminal between two adjacent positionings according to sensing data of an acceleration sensor between adjacent two positionings according to an embodiment, and determining a phase according to sensing data of an acceleration sensor between two adjacent positioning positions; The process of shifting the value of the terminal between two adjacent positionings specifically includes the following steps:

Step S310: Perform an integration operation on the sensing data of the acceleration sensor between two adjacent positioning to obtain a speed value. The speed can be obtained by integrating the acceleration.

Step S320: performing a second integral operation on the velocity value to obtain a displacement value of the terminal between adjacent two positionings. The distance (displacement) can be obtained by the speed integral operation.

Through the above steps, the displacement value of the terminal can also be obtained.

The reference displacement value and the reference positioning frequency may be preset; or, the reference displacement value and the reference positioning frequency may be displacement values and positioning frequencies of the terminal between the previous two adjacent positioning.

When the reference displacement value and the reference positioning frequency are preset, for example, the reference displacement value may be The preset positioning frequency can be preset to F0 (for example, 10 seconds/time, that is, F0=0.1HZ) by being set to S0 (for example, 20 meters) in advance. When the displacement value of the terminal between the two adjacent positioning is measured as S1 (for example, 40 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is increased relative to the reference positioning frequency F0, for example, to F1 (for example, 5 seconds/time). , ie F1=0.2HZ). When the displacement value of the terminal between the two adjacent positioning is measured as s1 (for example, 10 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is lowered relative to the reference positioning frequency F0. For example, reduce to f1 (for example, 20 seconds/time).

When the reference displacement value and the reference positioning frequency are the displacement value and the positioning frequency of the terminal between the previous two adjacent positioning, for example, the reference displacement value may be set to the above S1 (for example, 40 meters), and the reference positioning frequency may be set. It is the above F1 (for example, 5 seconds/time, that is, F1 = 0.2HZ). When the displacement value of the terminal between the two adjacent positioning is measured as S2 (for example, 50 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is increased relative to the reference positioning frequency F1, for example, to F2 (for example, 4 seconds/time). , ie F2 = 0.25HZ). When the displacement value of the terminal between two adjacent positioning is measured as s2 (for example, 20 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is lowered relative to the reference positioning frequency F1, for example, to f2 (for example, 10 seconds/time) ).

When making adjustments, the amplitude of the displacement of the terminal between the two adjacent positioning positions is generally increased or decreased relative to the reference displacement value, and the positioning frequency is adjusted accordingly so that the amplitude of the positioning frequency is increased or decreased relative to the reference positioning frequency. . Specifically, the greater the magnitude of the displacement of the terminal relative to the reference displacement value between adjacent two positionings, the corresponding adjustment of the positioning frequency is such that the positioning frequency is increased relative to the reference positioning frequency; The greater the magnitude of the displacement of the inter-terminal displacement relative to the reference displacement value, the greater the magnitude of the reduction of the positioning frequency relative to the reference positioning frequency.

For example, the reference displacement value may be preset to S0 (for example, 20 meters), and the reference positioning frequency may be preset to F0 (for example, 10 seconds/time, that is, F0=0.1HZ). When the displacement value of the terminal between the two adjacent positioning is measured as S1 (for example, 40 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is increased relative to the reference positioning frequency F0, for example, to F1 (for example, 5 seconds/time). , ie F1=0.2HZ). Calculated in units of HZ, the value of the positioning frequency F1 can be obtained according to the formula of S0/F0=S1/F1.

Of course, the adjustment of the positioning frequency needs to be within a certain range. After all, for the positioning, the positioning frequency has a certain range, and the excessive positioning frequency may not be supported by the positioning module. This leads to excessive power consumption; too low a positioning frequency results in low positioning accuracy. Therefore, when adjusting, it is necessary to appropriately limit the size of the positioning frequency. The restrictions are as follows:

If the adjusted positioning frequency is greater than the maximum reference positioning frequency Fmax (for example, 1 second/time, that is, Fmax=1HZ), the positioning frequency is updated to the maximum reference positioning frequency Fmax. If the adjusted positioning frequency is less than the minimum reference positioning frequency Fmin (for example, 30 minutes/time, that is, Fmin=1/1800HZ), the positioning frequency is updated to the minimum reference positioning frequency Fmin. For example, if the adjusted positioning frequency is 0.5 second/time (2HZ) and is greater than the maximum reference positioning frequency Fmax, the positioning frequency is updated to the maximum reference positioning frequency Fmax. If the adjusted positioning frequency is 40 minutes/time (1/2400HZ) and less than the minimum reference positioning frequency Fmin, the positioning frequency is updated to the minimum reference positioning frequency Fmin.

If the reference displacement value and the reference positioning frequency are preset, it is necessary to perform pre-initialization setting of the reference displacement value and the reference positioning frequency. Moreover, if the reference displacement value and the reference positioning frequency are the displacement values and the positioning frequencies of the terminal between the previous two adjacent positionings, it is also necessary to perform pre-initialization setting of the reference displacement value and the reference positioning frequency. Therefore, the terminal positioning frequency adjustment method may further include a pre-step S100 before step S110.

Step S100: Perform pre-initialization setting on the reference displacement value and the reference positioning frequency.

The pre-initialization setting of the reference displacement value and the reference positioning frequency described above may be set by the user or may be preset in the product design. Of course, if it is preset in the product design, the reference displacement value and the reference positioning frequency can also be changed by the user at this time. Therefore, a user interface can be provided for receiving pre-initialization settings for the reference displacement value and the reference positioning frequency, and the user can pre-initialize setting or changing the reference displacement value and the reference positioning frequency through the user interface.

A terminal positioning frequency adjustment system will be described below.

4 is a schematic diagram of a terminal positioning frequency adjustment system of an embodiment. A terminal positioning frequency adjustment system includes: a positioning module 110, a listener module 120, and an adjustment module 130.

The positioning module 110 is configured to perform positioning in accordance with a known positioning frequency. The known positioning frequency may be the already confirmed positioning frequency. For example, when the positioning module 110 is just started, it may be a preset positioning frequency; for example, after the method is started, it may be the positioning frequency confirmed by the previous adjustment round. The positioning module 110 can include a Beidou positioning module, a GPS positioning module, and the like.

The listener module 120 is configured to read the sensing data of the acceleration sensor. The positioning frequency is adjusted when the sensing data satisfies a preset condition. The sensing data of the acceleration sensor can be monitored and read by the monitor module 120, that is, the sensing data of the acceleration sensor is periodically read to monitor the sensing data change of the acceleration sensor.

The scenario configuration data is used to determine a motion scenario of the terminal, such as a motion scenario for determining that the terminal user is stationary, walking, running, jumping. For example, the scenario configuration data includes three axial acceleration data preset, for example, the scenario configuration data includes preset axial acceleration data of the X axis, the Y axis, and the Z axis. Generally speaking, when the user has a regular movement such as walking, running, jumping, etc., the acceleration sensor in the terminal will detect the regular sensing data accordingly. Of course, this regular sensing data needs to be combined with the specific application of the terminal. If the terminal is a wearable device (such as a smart bracelet or a smart watch), there will be regular sensing data to characterize the user walking, running, jumping; It is a smart terminal device (such as a smart phone), and there are also other regular sensing data to characterize the user walking, running, jumping.

Generally, when the end user is doing a rapid transfer movement (for example, walking, running, etc.), since it is necessary to ensure the positioning accuracy, it is necessary to increase the positioning frequency at this time. So, you can set The scenario configuration data is used to determine that the terminal is doing a fast transfer motion. When the sensing data of the acceleration sensor satisfies the scenario configuration data, it can be determined that the terminal user is performing a fast transition motion, that is, the sensing data meets the preset condition, and the positioning frequency can be adjusted.

Of course, the scenario configuration data may also be set to determine that the terminal determines that the sensing data meets the preset condition when performing a slow moving motion (such as walking or walking), and the positioning frequency may be adjusted. At this time, when the end user is performing the slow moving motion, the sensing data of the acceleration sensor is sensed, and the positioning frequency can be adjusted.

In some embodiments, the preset condition further includes a first preset condition. When the sensing data satisfies the first preset condition, the positioning is performed once and then the secondary positioning is performed according to the known positioning frequency. This is because if the end user is doing a fast transfer movement, due to the rapid change of position, if there is no immediate positioning, there may be a large position blank during this time. Therefore, the scenario configuration data included in the first preset adjustment may be used to determine that the end user is doing a quick transfer motion, such as running, riding, and the like. Taking the acceleration sensor as an example, when the sensing data sensed by the acceleration sensor satisfies the first preset adjusted scene configuration data (for example, it may be in a range), it is determined that the sensing data satisfies the first preset condition.

The adjustment module 130 is configured to adjust the positioning frequency according to the increase or decrease of the displacement value of the terminal between the two adjacent positioning positions after the sensing data satisfies the preset adjustment, so that the positioning frequency is relative to the reference positioning frequency. Increase or decrease.

The displacement value of the terminal between adjacent two positionings may be determined according to positioning data of two adjacent positionings. 2 is a schematic flowchart of determining a displacement value of a terminal between adjacent two positionings according to positioning data of two adjacent positioning according to an embodiment, and determining a terminal between two adjacent positioning according to positioning data of two adjacent positionings The process of shifting the value specifically includes the following steps:

Step S210: The driving positioning module 110 performs the first positioning (the first time of the above two adjacent positionings) to obtain the first geographical location data. The first geographic location data may be satellite positioning data, such as GPS positioning data (positioning data including latitude and longitude coordinate data).

Step S220: According to the known positioning frequency, the driving positioning module 110 performs secondary positioning (the second time of the above two adjacent positionings) to obtain the second geographical location data. Similarly, the second geographic location data may be satellite positioning data, such as GPS positioning data (positioning data including latitude and longitude coordinate data).

When the reference displacement value and the reference positioning frequency are preset, for example, the reference displacement value may be preset to S0 (for example, 20 meters), and the reference positioning frequency may be preset to F0 (for example, 10 seconds/time, that is, F0= 0.1HZ). When the displacement value of the terminal between the two adjacent positioning is measured as S1 (for example, 40 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is increased relative to the reference positioning frequency F0, for example, to F1 (for example, 5 seconds/time). , ie F1=0.2HZ). When the displacement value of the terminal between the two adjacent positioning is measured as s1 (for example, 10 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is lowered relative to the reference positioning frequency F0. For example, reduce to f1 (for example, 20 seconds/time).

When the reference displacement value and the reference positioning frequency are the displacement value and the positioning frequency of the terminal between the previous two adjacent positioning, for example, the reference displacement value may be set to the above S1 (for example, 40 meters), and the reference positioning frequency may be set. It is the above F1 (for example, 5 seconds/time, that is, F1 = 0.2HZ). When the displacement value of the terminal between the two adjacent positioning is measured as S2 (for example, 50 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is increased relative to the reference positioning frequency F1, for example, to F2 (for example, 4 seconds/time, that is, F2=0.25HZ). When the displacement value of the terminal between two adjacent positioning is measured as s2 (for example, 20 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is lowered relative to the reference positioning frequency F1, for example, to f2 (for example, 10 seconds/time) ).

For example, the reference displacement value may be preset to S0 (for example, 20 meters), and the reference positioning frequency may be preset to F0 (for example, 10 seconds/time, that is, F0=0.1HZ). When the displacement value of the terminal between the two adjacent positioning is measured as S1 (for example, 40 meters), the positioning frequency is adjusted accordingly so that the positioning frequency is increased relative to the reference positioning frequency F0, for example, to F1 (for example, 5 seconds/time). , ie F1=0.2HZ). The value of the positioning frequency F1 can be obtained according to the formula of S0/F0=S1/F1.

Of course, the adjustment of the positioning frequency needs to be within a certain range. After all, for positioning, the positioning frequency has a certain range. If the positioning frequency is too high, the positioning module may not support, and the power consumption is too large; the positioning is too low. The frequency results in low positioning accuracy. Therefore, when adjusting, it is necessary to appropriately limit the size of the positioning frequency. The restrictions are as follows:

If the reference displacement value and the reference positioning frequency are preset, it is necessary to perform pre-initialization setting of the reference displacement value and the reference positioning frequency. Moreover, if the base displacement value and base When the quasi-positioning frequency is the displacement value and the positioning frequency of the terminal between the previous two adjacent positioning, the pre-initial setting of the reference displacement value and the reference positioning frequency is also required. Therefore, the terminal positioning frequency adjustment system further includes a preset module 100 configured to pre-initialize the reference displacement value and the reference positioning frequency.

The pre-initialization setting of the reference displacement value and the reference positioning frequency described above may be set by the user or may be preset in the product design. Of course, if it is preset in the product design, the reference displacement value and the reference positioning frequency can also be changed by the user at this time. Therefore, the preset module 100 can provide a user interface for receiving pre-initialization settings for the reference displacement value and the reference positioning frequency, and the user can pre-initialize the setting or changing the reference displacement value and the reference positioning frequency through the user interface.

The adjustment of the positioning frequency can be achieved by adjusting the interval time required for the next positioning, that is, by adjusting the increase or decrease of the positioning interval of the adjacent two positionings to adjust the positioning frequency such that the positioning frequency is increased or decreased relative to the reference positioning frequency. For example, if the positioning frequency needs to be adjusted so that the positioning frequency is increased relative to the reference positioning frequency, the positioning interval of the adjacent two positioning positions can be reduced; if the positioning frequency needs to be adjusted such that the positioning frequency is lower than the reference positioning frequency, the adjacent two times can be increased. The positioning interval for positioning.

The terminal positioning frequency adjustment method and system described above identify the motion of the terminal user according to the sensing data of the acceleration sensor, and then the terminal adjusts the positioning frequency according to the motion state of the user, so that the terminal positioning can ensure the positioning accuracy and ensure the lower work. Consumption. The terminal may be a wearable device, for example, a smart wristband or a smart watch; of course, it may also be a smart terminal device, such as a smart phone. When the user carries the above terminal, other people who are in communication with the above terminal can know the location of the user. For example, when the user is a child or an elderly person, the guardian of the user can more accurately understand the location of the user, and the terminal has lower power consumption than the conventional terminal, improves the endurance of the terminal, and the positioning accuracy is ensured.

A method of adjusting the positioning interval of a terminal will be described below.

FIG. 5 is a schematic flow chart of a method for adjusting a positioning interval of a terminal according to an embodiment. A terminal positioning interval adjustment method includes the following steps:

Step S410: Perform positioning according to a known positioning interval. The known positioning interval can be already The confirmed positioning interval, for example, at the beginning of the method, may be a preset positioning interval; for example, after the method is started, it may be the positioning interval confirmed by the previous adjustment round.

Step S420: Read the sensing data of the acceleration sensor. After the sensing data satisfies the preset condition, step S430 is performed. The sensing data of the acceleration sensor can be monitored and read by the monitor, that is, the sensing data of the acceleration sensor is periodically read to monitor the change of the sensing data of the acceleration sensor.

Usually, when the end user is doing a quick transfer exercise (such as walking, running, etc.) Since it is necessary to ensure the positioning accuracy, it is necessary to reduce the positioning interval (equivalent to increasing the positioning frequency). Therefore, the scenario configuration data can be set to determine that the terminal is doing a fast transfer motion. When the sensing data of the acceleration sensor satisfies the scenario configuration data, it can be determined that the terminal user is performing a fast transition motion, that is, the sensing data meets the preset condition, and the positioning interval adjustment state can be entered, and step S430 is performed.

Of course, the scenario configuration data may also be set to determine that the terminal determines that the sensing data meets the preset condition when performing a slow moving motion (eg, walking, walking), and may enter the positioning interval adjustment state. At this time, when the end user is performing the slow moving motion, the sensing data of the acceleration sensor is sensed, and the positioning interval adjustment state can be entered, and step S430 is performed.

Step S430: After the sensing data meets the preset condition, according to the increase or decrease of the displacement value of the terminal between the adjacent two positionings, the positioning interval is adjusted correspondingly, so that the positioning interval is decreased or increased relative to the reference positioning interval. Big.

The displacement value of the terminal between adjacent two positionings may be determined according to positioning data of two adjacent positionings. 6 is a schematic flowchart of determining a displacement value of a terminal between adjacent two positionings according to positioning data of two adjacent positioning according to an embodiment, and determining a terminal between two adjacent positioning according to positioning data of two adjacent positioning The process of shifting the value specifically includes the following steps:

Step S510: The driving positioning module performs the first positioning (the first time of the above two adjacent positionings) to obtain the first geographical location data. The first geographic location data may be satellite positioning data, such as GPS positioning data (positioning data including latitude and longitude coordinate data).

Step S520: After the known positioning interval, the driving positioning module performs secondary positioning (the second time of the above two adjacent positionings) to obtain the second geographical location data. Similarly, the second geographic location data may be satellite positioning data, such as GPS positioning data (positioning data including latitude and longitude coordinate data).

Step S530: Calculate the distance obtained by using the second geographical position data and the coordinate difference value of the first geographical location data as the displacement value of the terminal. For example, if the first geographic location data is (X1, Y1) and the second geographic location data is (X2, Y2), the displacement value of the terminal can be obtained as

The reference displacement value and the reference positioning interval may be preset; or, the reference displacement value and the reference positioning interval may be displacement values and positioning intervals of the terminal between the previous two adjacent positioning.

When the reference displacement value and the reference positioning interval are set in advance, for example, the reference displacement value may be previously set to S0 (for example, 20 meters), and the reference positioning interval may be set to T0 (for example, 10 seconds) in advance. When it is determined that the displacement value of the terminal between adjacent two positionings is S1 (for example, 40 meters), the positioning interval is adjusted accordingly such that the positioning interval is reduced with respect to the reference positioning interval T0, for example, to T1 (for example, 5 seconds). When the displacement value of the terminal between the two adjacent positioning is measured as s1 (for example, 10 meters), the positioning interval is adjusted accordingly so that the positioning interval is increased relative to the reference positioning interval T0, for example, to t1 (for example, 20 seconds). ).

When the reference displacement value and the reference positioning interval are the displacement values and the positioning intervals of the terminal between the previous two adjacent positioning, for example, the reference displacement value may be set to the above S1 (for example, 40 meters), and the reference positioning interval may be set. It is T1 above (for example, 5 seconds). When it is determined that the displacement value of the terminal between adjacent two positionings is S2 (for example, 50 meters), the positioning interval is adjusted accordingly such that the positioning interval is reduced with respect to the reference positioning interval T1, for example, to T2 (for example, 4 seconds). When the displacement value of the terminal between two adjacent positioning is measured as s2 (for example, 20 meters), at this time The positioning interval is adjusted accordingly such that the positioning interval is increased relative to the reference positioning interval T1, for example to t2 (for example 10 seconds).

When making adjustments, generally, the magnitude of the displacement value of the terminal between the adjacent two positioning positions is increased or decreased relative to the reference displacement value, and the corresponding adjustment positioning interval is such that the positioning interval is decreased or increased relative to the reference positioning interval. Big. Specifically, the greater the magnitude of the displacement of the terminal relative to the reference displacement value between the two adjacent positionings, the corresponding adjustment of the positioning interval is such that the positioning interval is decreased relative to the reference positioning interval; The greater the magnitude of the displacement of the inter-terminal displacement relative to the reference displacement value, the correspondingly adjusting the positioning interval such that the amplitude of the positioning interval increases relative to the reference positioning interval.

For example, the reference displacement value may be previously set to S0 (for example, 20 meters), and the reference positioning interval may be previously set to T0 (for example, 10 seconds). When it is determined that the displacement value of the terminal between adjacent two positionings is S1 (for example, 40 meters), the positioning interval is adjusted accordingly such that the positioning interval is reduced with respect to the reference positioning interval T0, for example, to T1 (for example, 5 seconds). The value of the positioning interval T1 can be obtained according to the formula of S0 × T0 = S1 × T1.

Of course, the adjustment of the positioning interval needs to be within a certain range. After all, for the positioning, the positioning interval has a certain range. If the positioning interval is too small, the positioning module may not support the power consumption, and the power consumption is too large; Intervals result in low positioning accuracy. Therefore, when adjusting, it is necessary to appropriately limit the size of the positioning interval. The restrictions are as follows:

If the adjusted positioning interval is greater than the maximum reference positioning interval Tmax (for example, 30 minutes), the positioning interval is updated to the maximum reference positioning interval Tmax. If the adjusted positioning interval is less than the minimum reference positioning interval Tmin (for example, 1 second), the positioning interval is updated to the minimum reference positioning interval Tmin. For example, if the adjusted positioning interval is 0.5 seconds and less than the minimum reference positioning interval Tmin (1 second), the positioning interval is updated to the minimum reference positioning interval Tmin (1 second). If the adjusted positioning interval is 40 minutes, which is greater than the maximum reference positioning interval Tmax (30 minutes), the positioning interval is updated to the maximum reference positioning interval Tmax (30 minutes).

If the reference displacement value and the reference positioning interval are set in advance, it is necessary to perform pre-initialization setting of the reference displacement value and the reference positioning interval. Moreover, if the reference displacement value and the reference positioning interval are the displacement values and the positioning intervals of the terminal between the previous two adjacent positionings, the pre-initialization setting of the reference displacement value and the reference positioning interval is also required. Therefore, the terminal positioning interval adjustment method may further include a pre-step S400 before step S410.

Step S400: Perform pre-initialization setting on the reference displacement value and the reference positioning interval.

The pre-initialization setting of the reference displacement value and the reference positioning interval described above may be set by the user or may be preset in the product design. Of course, if it is preset in the product design, the reference displacement value and the reference positioning interval can also be changed by the user at this time. Accordingly, a user interface can be provided for receiving pre-initialization settings for the reference displacement value and the reference positioning interval, and the user can pre-initialize settings or changes to the reference displacement value and the reference positioning interval through the user interface.

A terminal positioning interval adjustment system will be described below.

FIG. 7 is a schematic diagram of a terminal positioning interval adjustment system of an embodiment. A terminal positioning interval adjustment system includes: a positioning module 410, a listener module 420, and an adjustment module 430.

The positioning module 410 is configured to perform positioning at known positioning intervals. The known positioning interval may be an already determined positioning interval. For example, when the positioning module 410 is just started, it may be a preset positioning interval; for example, after the method is started, it may be the positioning interval confirmed by the previous adjustment round. The positioning module 410 can include a Beidou positioning module, a GPS positioning module, and the like.

The listener module 420 is configured to read the sensing data of the acceleration sensor. The positioning interval is adjusted when the sensing data satisfies the preset condition. The sensing data of the acceleration sensor can be monitored and read by the monitor module 420, that is, the sensing data of the acceleration sensor is periodically read to monitor the sensing data change of the acceleration sensor.

The scenario configuration data is used to determine a motion scenario of the terminal, such as a motion scenario for determining that the terminal user is stationary, walking, running, jumping. For example, the scenario configuration data includes three axial acceleration data preset, for example, the scenario configuration data includes preset axial acceleration data of the X axis, the Y axis, and the Z axis. Generally, users are walking, running, jumping, etc. When there is a certain regular motion, the acceleration sensor in the terminal will detect the regular sensing data accordingly. Of course, this regular sensing data needs to be combined with the specific application of the terminal. If the terminal is a wearable device (such as a smart bracelet or a smart watch), there will be regular sensing data to characterize the user walking, running, jumping; It is a smart terminal device (such as a smart phone), and there are also other regular sensing data to characterize the user walking, running, jumping.

Generally, when the end user is doing a rapid transfer movement (for example, walking, running, etc.), since it is necessary to ensure the positioning accuracy, it is necessary to reduce the positioning interval (equivalent to increasing the positioning frequency). Therefore, the scenario configuration data can be set to determine that the terminal is doing a fast transfer motion. When the sensing data of the acceleration sensor satisfies the scenario configuration data, it can be determined that the terminal user is performing a fast transition motion, that is, the sensing data meets the preset condition, and the positioning interval can be adjusted.

Of course, the scenario configuration data may also be set to determine that the terminal determines that the sensing data meets the preset condition when performing a slow moving motion (eg, walking, walking), and the positioning interval may be adjusted. At this time, when the end user is performing the slow moving motion, the sensing data of the acceleration sensor is sensed, and the positioning interval can be adjusted.

The adjustment module 430 is configured to adjust the displacement value of the terminal relative to the reference displacement value according to the increase or decrease of the displacement value between the two adjacent positioning positions after the sensing data satisfies the preset adjustment The bit spacing reduces or increases the positioning interval relative to the reference positioning interval.

When the reference displacement value and the reference positioning interval are preset, for example, the reference displacement value may be The preset positioning interval may be previously set to T0 (for example, 10 seconds) by being set to S0 (for example, 20 meters) in advance. When it is determined that the displacement value of the terminal between adjacent two positionings is S1 (for example, 40 meters), the positioning interval is adjusted accordingly such that the positioning interval is reduced with respect to the reference positioning interval T0, for example, to T1 (for example, 5 seconds). When the displacement value of the terminal between the two adjacent positioning is measured as s1 (for example, 10 meters), the positioning interval is adjusted accordingly so that the positioning interval is increased relative to the reference positioning interval T0, for example, to t1 (for example, 20 seconds). ).

When the reference displacement value and the reference positioning interval are the displacement values and the positioning intervals of the terminal between the previous two adjacent positioning, for example, the reference displacement value may be set to the above S1 (for example, 40 meters), and the reference positioning interval may be set. It is T1 above (for example, 5 seconds). When it is determined that the displacement value of the terminal between adjacent two positionings is S2 (for example, 50 meters), the positioning interval is adjusted accordingly such that the positioning interval is reduced with respect to the reference positioning interval T1, for example, to T2 (for example, 4 seconds). When the displacement value of the terminal between the two adjacent positioning is measured as s2 (for example, 20 meters), the positioning interval is adjusted accordingly so that the positioning interval is increased relative to the reference positioning interval T1, for example, to t2 (for example, 10 seconds). ).

If the reference displacement value and the reference positioning interval are set in advance, it is necessary to perform pre-initialization setting of the reference displacement value and the reference positioning interval. Moreover, if the reference displacement value and the reference positioning interval are the displacement values and the positioning intervals of the terminal between the previous two adjacent positionings, the pre-initialization setting of the reference displacement value and the reference positioning interval is also required. Therefore, the terminal positioning interval adjustment system further includes a preset module 400 configured to pre-initialize the reference displacement value and the reference positioning interval.

The pre-initialization setting of the reference displacement value and the reference positioning interval described above may be set by the user or may be preset in the product design. Of course, if it is preset in the product design, the reference displacement value and the reference positioning interval can also be changed by the user at this time. Therefore, the preset module 400 can provide a user interface for receiving pre-initialization settings for the reference displacement value and the reference positioning interval, and the user can pre-initialize the setting or change of the reference displacement value and the reference positioning interval through the user interface.

The terminal positioning interval adjustment method and system are configured to identify the motion of the terminal user according to the sensing data of the acceleration sensor, and then the terminal adjusts the positioning interval according to the motion state of the user, so that the terminal positioning can ensure the positioning accuracy and ensure the lower work. Consumption. The terminal may be a wearable device, for example, a smart wristband or a smart watch; of course, it may also be a smart terminal device, such as a smart phone. When the user carries the above terminal, other people who are in communication with the above terminal can know the location of the user. For example, when the user is a child or an elderly person, the guardian of the user can more accurately understand the location of the user, and the terminal has lower power consumption than the conventional terminal, improves the endurance of the terminal, and the positioning accuracy is ensured.
