Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be noted that the terms "first", "second", and the like in the description and claims of the present invention are used for distinguishing different objects, and are not used for describing a specific order. The terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the invention discloses a real-time positioning method and wearable equipment, which can reduce the power consumption of the equipment so as to improve the cruising ability of a battery. The method is suitable for electronic equipment such as smart phones, tablet computers, smart watches, smart bracelets and even smart glasses. The operating systems of various electronic devices include, but are not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a Black Berry operating system, a Windows Phone8 operating system, and the like. The embodiment of the invention is described by taking an electronic device or a wearable device as an execution main body, and it should be understood that the invention should not be limited in any way. The following detailed description is made with reference to the accompanying drawings.

Example one

Referring to fig. 1, fig. 1 is a schematic flow chart of a real-time positioning method according to an embodiment of the present invention. As shown in fig. 1, the real-time positioning method may include the steps of:

101. the electronic device obtains starting point positioning information of an initial positioning period.

102. And when the initial positioning period is finished, the electronic equipment acquires the end positioning information of the initial positioning period. The initial positioning period refers to a first positioning period in which the electronic device starts to perform real-time positioning. The size of the positioning period may specifically be 3 seconds. Of course, the size of the positioning period may be other values besides 3 seconds, for example, 2.6 seconds, 3.8 seconds, and the like, and the size of the positioning period is not particularly limited in the embodiment of the present invention.

When the electronic device is located, that is, when the start point location information and the end point location information of the initial location period are obtained, a common Global Positioning System (GPS) technology, a base station location technology, a network location technology, or the like may be adopted, and specifically, what kind of location mode is adopted to locate the electronic device is adopted, which is not limited in the embodiment of the present invention. Wherein the positioning information comprises longitude and latitude information. That is, each time the electronic device is located, a pair of coordinate values of shape (lat) can be obtained. Where lat refers to latitude and long refers to longitude.

As an optional implementation manner, the electronic device includes a wearable device that is usually worn by a child user, and after step 101 is executed, the wearable device may determine whether a location corresponding to the starting point positioning information belongs to a preset safety area; if yes, step 102 may include: when the initial positioning period is finished, the wearable equipment monitors the motion state of the wearable equipment through the sensor; and if the motion state is used for describing that the current position is changed, executing the step of acquiring the end point positioning information of the initial positioning period.

Further optionally, if the motion state is used to describe that the current position is not changed, the initial positioning period is extended. When the motion state is a static state, a vibration state, a free-fall motion state and/or an angular motion state, the wearable device judges that the motion state of the wearable device is used for describing that the current position is not changed.

It can be understood that if the position of the wearable device in the positioning period is not changed, the start point positioning information and the end point positioning information of the wearable device are still obtained, which will cause unnecessary power consumption and affect the battery endurance of the wearable device. Therefore, by implementing the above embodiment, when the wearable device is in the preset safety region and there is no position change in the initial positioning period, the initial positioning period is extended, the power consumption of the device can be reduced, and the cruising ability of the battery can be improved.

Further optionally, if the motion state is used to describe that the current position changes, after the step of obtaining the end point positioning information of the initial positioning period is executed, the wearable device may further obtain a first electronic fence in which a position corresponding to the start point positioning information is located, and determine whether the position corresponding to the end point positioning information is located in the first electronic fence, if so, still use a first preset duration corresponding to the first electronic fence as a duration of a next positioning period, where the first preset duration corresponding to the first electronic fence is the duration of the initial positioning period; if not, the time length of a second period corresponding to a second electronic fence in which the position corresponding to the end point positioning information is located is used as the time length of the next positioning period, and prompt information used for describing that the wearable device is switched from the first electronic fence to the second electronic fence is sent to the mobile terminal bound by the wearable device.

According to the implementation of the embodiment, the positioning period is adaptively set and updated according to the electronic fence where the terminal positioning information is located, so that the power consumption of the device can be reduced, the communication traffic between the wearable device and the server can be reduced, and the cruising ability of the battery can be improved. In addition, after the wearable device is switched to the electronic fence, prompt information is sent to the bound mobile terminal (namely, the household terminal), and the safety of the wearable device user (namely, children) can be protected in a more targeted mode.

103. And the electronic equipment acquires the virtual positioning track according to the starting point positioning information and the end point positioning information.

It should be noted that the virtual positioning track may be a straight line connecting between the positioning points corresponding to the start point positioning information and the end point positioning information, or a curved line connecting between two positioning points, and the present invention is not limited specifically.

104. The electronic equipment divides the virtual positioning track into N sections to obtain N-1 pieces of virtual positioning information, wherein N is a positive integer larger than 1.

The positive integer N may be set by a developer according to actual conditions.

105. The electronic equipment takes 1/N duration of the initial positioning period as an updating time interval.

106. And the electronic equipment performs positioning updating according to the starting point positioning information, the N-1 pieces of virtual positioning information and the end point positioning information step by step in the next positioning period for N +1 times according to the updating time interval.

It can be understood that the duration of the next positioning period is the same as the duration of the initial positioning period, and after the initial positioning period, steps 103-106 are executed in a loop. That is, at the beginning of the next positioning period, the positioning update is performed according to the N +1 positioning information obtained from the initial positioning period, and meanwhile, the start point positioning information and the end point positioning information of the current positioning period are also obtained for performing the positioning update in the next positioning period.

Implementing the method described in fig. 1, by obtaining the starting point positioning information of the initial positioning period, and waiting until the initial positioning period is finished, obtaining the end point positioning information of the initial positioning period, then obtaining the virtual positioning track according to the two positioning information, dividing the virtual positioning track into N segments to obtain N-1 pieces of virtual positioning information, finally taking the 1/N duration of the initial positioning period as the updating time interval, and gradually performing positioning updating according to the starting point positioning information, the N-1 pieces of virtual positioning information and the end point positioning information in N +1 times in the next positioning period, thereby, in a larger positioning period, only needing to perform two times of accurate positioning, performing multiple times of positioning updating in the next positioning period with a smaller time interval, and because the number of times of accurate positioning is reduced, the power consumption of the device can be reduced, thereby improving the endurance of the battery, meanwhile, the positioning updating can be carried out in real time, and the balance between the reduction of the power consumption of the equipment and the real-time positioning is kept to a greater extent.

Example two

Referring to fig. 2, fig. 2 is a schematic flow chart of another real-time positioning method according to an embodiment of the invention. As shown in fig. 2, the real-time positioning method may include the steps of:

201 to 204. For the description of steps 201 to 204, please refer to the detailed description of steps 101 to 104 in the first embodiment, which is not repeated herein.

205. The electronic device obtains the actual moving speed of the initial positioning period.

As an alternative embodiment, after step 205 is executed, the following steps may also be executed:

the electronic equipment detects whether the electronic equipment is in an electronic map navigation mode; if the electronic map is in the navigation mode, the electronic equipment judges whether the actual moving speed reaches a preset speed threshold value; if the preset speed threshold is reached and the electronic identifier corresponding to the electronic equipment is not displayed in the map visible area on the current display interface, the electronic equipment adjusts the map visible area on the current display interface according to the starting point positioning information and the end point positioning information so that the display position of the electronic identifier on the current display interface is unchanged, and the adjusted map visible area is displayed on the current display interface. The adjusted map visible area comprises accurate positioning points corresponding to the starting point positioning information and the end point positioning information respectively, and a virtual positioning track.

Further optionally, after the adjusted map visible area is displayed on the display interface, a sliding operation instruction input by a user on the display interface may be further received, and the map visible area is adjusted according to the sliding operation instruction.

By implementing the implementation of the embodiment, the moving state of the electronic equipment is judged according to the actual moving speed in the electronic map navigation mode, if the actual moving speed reaches the preset speed threshold value and the electronic identifier corresponding to the electronic equipment is not displayed in the map visible area on the current display interface, the map visible area on the current display interface can be adjusted according to the starting point positioning information and the end point positioning information, and the adjusted map visible area including the accurate positioning points and the virtual positioning tracks corresponding to the starting point positioning information and the end point positioning information is displayed, so that the display effect of the electronic map is optimized.

206. And the electronic equipment adjusts the positioning period to obtain the duration of the next positioning period according to the actual moving speed.

It can be understood that the faster the actual moving speed is, the shorter the positioning period should be, otherwise, the distance between the start point positioning information and the end point positioning information is too large to ensure accurate positioning update.

Specifically, optionally, step 206 may include: the electronic equipment calculates the difference value between the actual moving speed and the preset moving speed; if the actual moving speed is greater than the preset moving speed and the difference value is greater than the preset threshold value, the electronic equipment shortens the positioning period by the preset time quantum to obtain shorter duration of the next positioning period; if the actual moving speed is less than the preset moving speed and the difference value is greater than the preset threshold value, the electronic equipment prolongs the positioning period by the preset time amount to obtain the longer duration of the next positioning period.

And step 205-207 is implemented, the duration of the next positioning period is adaptively adjusted according to the actual moving speed of the positioning period, so that the power consumption of the equipment can be reduced, the communication traffic with the server can be reduced, and the cruising ability of the battery can be improved.

207. The electronic equipment takes 1/N duration of the following positioning period as an updating time interval.

It should be noted that, since N +1 positioning points have been obtained in the initial positioning period, in order to perform positioning update uniformly in the next positioning period, the update time interval needs to be adjusted according to the duration of the next positioning period. For example, assuming that the original initial positioning period is 9 seconds, N is equal to 3, the update time interval is 3 seconds, and the duration of the next positioning period obtained after the positioning period is adjusted according to the actual moving speed is 12 seconds, and N remains unchanged, the update time interval is adjusted to 4 seconds.

208. And the electronic equipment performs positioning updating according to the starting point positioning information, the N-1 pieces of virtual positioning information and the end point positioning information step by step in the next positioning period for N +1 times according to the updating time interval.

Compared with the method described by implementing the method described by the fig. 1, the method described by the fig. 2 can also adaptively adjust the duration of the next positioning period according to the actual moving speed of the positioning period, can reduce the power consumption of the device, and can also reduce the communication traffic with the server, thereby improving the cruising ability of the battery.

EXAMPLE III

Referring to fig. 3, fig. 3 is a schematic flow chart of another real-time positioning method according to an embodiment of the present invention. As shown in fig. 3, the real-time positioning method may include the steps of:

301. the wearable device determines the duration of an initial positioning period, an updating time interval and a positive integer N according to a preset minimum period, a preset maximum waiting value and a target preset maximum period corresponding to the current mobile scene of the wearable device.

The preset minimum period is obtained according to power consumption limit parameters of the wearable device, the preset maximum waiting value is obtained according to feedback information of a plurality of users for positioning delay, the duration of the initial positioning period is not less than the preset minimum period, the duration of the initial positioning period is not greater than the target preset maximum period, the updating time interval is not greater than the preset maximum waiting value, and the updating time interval is 1/N duration of the initial positioning period. The power consumption limit parameters are hardware parameters of the wearable device, and if the power consumption reaches a threshold value in the power consumption limit parameters, the body performance of the wearable device can be considered to be unqualified.

It should be noted that the wearable device may acquire a historical movement speed of the wearable device in each preset movement scene in advance, and obtain a preset maximum period corresponding to each preset movement scene according to the historical movement speed; and determining a target preset moving scene matched with the current moving scene of the wearable device from each preset moving scene, and obtaining a target preset maximum period corresponding to the target preset moving scene.

For example, such as the wearable device user is sitting in a car, the preset maximum period may be 3 seconds or 5 seconds; assuming that the wearable device user is walking, the preset maximum period is approximately 10 seconds.

It can be understood that the location update of the wearable device is generally sent to the mobile terminal bound to the wearable device, so that the mobile terminal user (i.e. a parent) can know the location information of the wearable device user (i.e. a child), and therefore, in order to avoid a situation that the mobile terminal user waits for the location update for a long time to cause a negative emotion, feedback information of a plurality of mobile terminal users for location delay can be collected in advance, and according to the feedback information, a preset maximum waiting value is obtained, and the set update time interval is not greater than the preset maximum waiting value.

For example, assume that the preset minimum period is 2 seconds, the preset maximum waiting value is 3 seconds, and the target preset maximum period corresponding to the current moving scene of the wearable device is 11 seconds. Since the duration of the initial positioning period is greater than the update time interval, and the duration of the initial positioning period is N times the update time interval, where N is a positive integer greater than 1, the duration of the initial positioning period cannot be 2 seconds or 3 seconds. Then, if the duration of the initial positioning period is 4 seconds and the update time interval is 3 seconds, then the ratio of 4 seconds to 3 seconds is 1.33, and N is obtained after rounding up and is equal to 2, so that it is determined that the duration of the initial positioning period is 6 seconds, the update time interval is 3 seconds, and the positive integer N is equal to 2, or the duration of the initial positioning period is 4 seconds, and the update time interval is 2 seconds and the positive integer N is equal to 2.

For another example, if the duration of the initial positioning period is 10 seconds and the update time interval is 3 seconds, then the ratio of 10 seconds to 3 seconds is 3.33, and N is equal to 3 after rounding, so that the duration of the initial positioning period is determined to be 9 seconds, the update time interval is 3 seconds, and the positive integer N is equal to 3.

For another example, if the duration of the initial positioning period is 7.6 seconds, the update time interval is 2 seconds, the ratio of 7.6 seconds to 2 seconds is 3.8, and N is obtained after rounding, it is determined that the duration of the initial positioning period is 8 seconds, the update time interval is 2 seconds, and the positive integer N is equal to 4.

For example, if the duration of the initial positioning period is 8.4 seconds and the update time interval is 2.1 seconds, the positive integer N is equal to 4.

302. When a positioning function starting instruction input by a user of the mobile terminal bound with the wearable device is received, the wearable device detects whether the current GPS signal intensity of the wearable device reaches a preset intensity threshold value. If yes, go to step 303; otherwise, the flow is ended.

As an optional implementation manner, if the current GPS signal strength of the wearable device does not reach the preset strength threshold, the wearable device may send a prompt message for describing that the current GPS signal is weak to the bound mobile terminal, and when it is detected again that the current GPS signal strength reaches the preset strength threshold, step 303 is executed again. By implementing the embodiment, the situation that the mobile terminal user waits for the positioning update for a long time to cause negative emotion can be avoided, and the user experience is improved.

303. The wearable device uses the GPS to perform first positioning on the wearable device, and positioning information obtained by the first positioning is used as starting point positioning information of an initial positioning period.

As an optional implementation manner, after step 302 is executed, if the current GPS signal strength does not reach the preset strength threshold, the wearable device may further perform first positioning on the wearable device by using a WIFI positioning technology, and use positioning information obtained by the first positioning as start positioning information of an initial positioning period; and then when the current GPS signal intensity is detected again to reach the preset intensity threshold value, refreshing the positioning period, using the GPS to reposition the wearable equipment, and using the positioning information obtained by repositioning as the starting point positioning information of a new initial positioning period.

Implement this embodiment, can adopt WIFI location technique earlier to fix a position when the GPS signal is relatively weak, wait to when the GPS signal is strong enough, refresh the positioning cycle and reposition, can guarantee to fix a position the update to wearable equipment in real time, protect children user's safety better.

It is to be understood that since both GPS positioning technology and WIFI positioning technology relate to the prior art, the present invention will not be described in detail herein.

304. And when the initial positioning period is finished, the wearable device acquires the end point positioning information of the initial positioning period.

305. And the wearable equipment obtains a virtual positioning track according to the starting point positioning information and the end point positioning information.

306. The wearable device divides the virtual positioning track into N sections to obtain N-1 pieces of virtual positioning information, wherein N is a positive integer larger than 1.

307. The wearable device takes 1/N duration of the initial positioning period as an update time interval.

308. And the wearable equipment performs positioning updating according to the starting point positioning information, the N-1 virtual positioning information and the end point positioning information step by step in the next positioning period for N +1 times according to the updating time interval.

Compared with the method described by implementing the method described by fig. 1, the method described by implementing fig. 3 can also determine the preset minimum period according to the power consumption limit parameter of the wearable device, determining a preset maximum waiting value according to feedback information of a plurality of users for positioning delay, and determining a corresponding target preset maximum period according to a current moving scene of the wearable device, thereby setting parameters of the duration of the initial positioning period, the updating time interval and a positive integer N, so that the duration of the initial positioning period meets the condition that the duration is not less than the preset minimum period and not more than the target preset maximum period, the updating time interval meets the condition that the duration is not more than the preset maximum waiting value and is 1/N duration of the initial positioning period, therefore, the setting of the parameters is more reasonable and intelligent, the power consumption of the equipment is reduced while the real-time accurate positioning is realized, and the waiting emotion of the parent user is taken care of.

In addition, prompt information for describing the current weak GPS signal can be sent to the bound mobile terminal when the GPS signal is weak, so that the situation that a mobile terminal user waits for positioning update for a long time to cause negative emotion can be avoided, and user experience is improved; or adopt WIFI location technique earlier to fix a position, when the GPS signal is strong enough, refresh the location cycle and reposition, can guarantee to fix a position the update to wearable equipment in real time, protect children user's safety better.

the detection unit is used for monitoring the motion state of the wearable equipment through the sensor when the judgment unit judges that the position corresponding to the starting point positioning information belongs to the preset safety area and the initial positioning period is finished;

accordingly, the second positioning unit 402 is specifically configured to obtain the end point positioning information of the initial positioning period when the detection unit detects that the motion state of the wearable device is used to describe a change in the current position.

Further optionally, the wearable device shown in fig. 4 may further include an extension unit, configured to extend the initial positioning period when the detection unit detects that the motion state of the wearable device is used to describe that the current location is not changed.

And when the motion state is a static state, a vibration state, a free-fall motion state and/or an angular motion state, judging that the motion state of the wearable device is used for describing that the current position is not changed.

It can be understood that if the position of the wearable device in the positioning period is not changed, the start point positioning information and the end point positioning information of the wearable device are still obtained, which will cause unnecessary power consumption and affect the battery endurance of the wearable device. Therefore, when the wearable device is in the preset safety area and the position of the wearable device is not changed in the initial positioning period, the initial positioning period is prolonged, the power consumption of the device can be reduced, and the cruising ability of the battery is improved.

and the sending unit is used for sending prompt information for describing that the wearable device is switched from the first electronic fence to the second electronic fence to the mobile terminal bound with the wearable device when the judging unit judges that the position corresponding to the end point positioning information is not in the first electronic fence.

The wearable device shown in fig. 4 is implemented, by acquiring the starting point positioning information of the initial positioning period, and waiting for the end of the initial positioning period, acquiring the end point positioning information of the initial positioning period, then acquiring the virtual positioning track according to the two positioning information, dividing the virtual positioning track into N segments to acquire N-1 pieces of virtual positioning information, and finally taking the 1/N duration of the initial positioning period as the updating time interval, and performing positioning updating according to the starting point positioning information, the N-1 pieces of virtual positioning information and the end point positioning information step by step in the next positioning period for N +1 times, periodic positioning can be performed at a larger time interval, and then periodic positioning updating can be performed at a smaller time interval, so that within a larger positioning period, only two times of accurate positioning need to be performed, multiple positioning updating can be performed at a smaller time interval in the next positioning period, because the times of accurate positioning are reduced, the power consumption of the equipment can be reduced, the cruising ability of the battery is improved, meanwhile, the positioning updating can be carried out in real time, and the balance between the reduction of the power consumption of the equipment and the real-time positioning is kept to a greater extent.
