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 should be noted that the terms "comprises" and "comprising," and any variations thereof, of embodiments of the present invention are intended to cover non-exclusive inclusions, 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 power consumption control method of wearable equipment and the wearable equipment, which can reduce the power consumption of the wearable equipment when implementing a safety region guard reminding function. 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 illustrating a power consumption control method of a wearable device according to an embodiment of the present invention. As shown in fig. 1, the power consumption control method of the wearable device may include the steps of:

101. the wearable device acquires target base station data, wherein the target base station data comprises base station data of current connection of the wearable device and surrounding base station data scanned by the wearable device.

In embodiments of the present invention, wearable devices may include, but are not limited to, wrist-supported products (e.g., watches, wrists), foot-supported products (e.g., shoes, socks), head-supported products (e.g., glasses, helmets, headbands, hats, etc.), and smart clothing, bags, and the like.

In one embodiment, before acquiring the target base station data, the wearable device may determine whether a moving distance of the wearable device exceeds a specified safety distance, and if so, the target base station data is acquired, so that the number of times of acquiring the target base station data may be reduced, and the power consumption of the wearable device may be reduced. For example, the wearable device determining whether the movement distance of the wearable device exceeds a specified safety distance may include:

the wearable device starts a step counting sensor to detect the number of moving steps of a wearer of the wearable device;

and the wearable device obtaining a stride distance of a wearer of the wearable device;

and the wearable device calculates the moving distance of the wearer of the wearable device according to the moving step number and the striding distance;

and the wearable device judges whether the calculated moving distance exceeds a specified safety distance, and if so, the wearable device can acquire the target base station data, so that the frequency of acquiring the target base station data can be reduced, and the power consumption of the wearable device is reduced.

As an alternative embodiment, the wearable device obtaining the stride distance of the wearer of the wearable device may include:

the wearable equipment can shoot a face image of a wearer of the wearable equipment through the shooting module (such as a camera), and the face image is reported to the background service equipment, so that the background service equipment analyzes the identity information of the wearer of the wearable equipment according to the face image, the height data of the wearer of the wearable equipment is determined by the background service equipment according to the identity information of the wearer of the wearable equipment, and the step distance of the wearer of the wearable equipment is determined by the background service equipment according to the height data of the wearer of the wearable equipment;

and the wearable equipment acquires the stride distance of the wearer of the wearable equipment issued by the background service equipment.

By implementing the embodiment, the wearable device can flexibly obtain the stride information of different wearers even under the condition that the stride information of different wearers is not required to be stored in advance, and the workload brought by the need of periodically maintaining the stride information of different wearers when the wearable device stores the stride information of different wearers in advance is reduced.

As another optional implementation, after determining that the calculated moving distance exceeds the specified safe distance and before the wearable device acquires the target base station data, the wearable device may further perform the following steps:

the wearable device determines the field position of the wearable device corresponding to the time point when the moving distance exceeds the specified safe distance and the field air pressure value of the wearable device at the field position;

the wearable device determines the historical position of the wearable device corresponding to the time point of turning on the step counting sensor and the historical air pressure value of the wearable device at the historical position;

and the wearable device judges whether the distance between the field position and the historical position on the horizontal plane is smaller than the specified safe distance, if so, the wearable device judges whether the difference value between the field air pressure value and the historical air pressure value exceeds a specified threshold value, if so, the wearable device can consider that the moving step number is the moving step number generated when a wearer of the wearable device moves up and down in a building space of a safe area, at the moment, the possibility that the wearer of the wearable device is located in the safe area is higher, and accordingly, the wearable device can not acquire target base station data even if the calculated moving distance exceeds the specified safe distance; if the wearable device determines that the distance between the field position and the historical position on the horizontal plane is greater than or equal to the specified safe distance, and the wearable device determines that the difference between the field air pressure value and the historical air pressure value does not exceed the specified threshold, the wearable device may consider that the moving step number is the moving step number generated when the wearer of the wearable device moves on the horizontal plane of the safe area, and when the calculated moving distance exceeds the specified safe distance, the wearer of the wearable device is less likely to be located in the safe area, and the wearable device may obtain the target base station data.

By the implementation of the embodiment, the accuracy of the wearable device for acquiring the target base station data can be improved.

102. The wearable device judges whether the target base station data comprises basic base station data, wherein the basic base station data is base station data collected when the wearable device historically locates in a certain safety area, and if yes, the steps 103-104 are executed; if not, the flow is ended.

Wherein the base station data collected by the wearable device when historically located within a certain security area may include a base station ID.

In one embodiment, the wearable device may store base station data, and the wearable device may periodically update the base station data.

Further, before the wearable device stores the basic base station data, whether the condition of positioning the stored basic base station data is met or not can be detected, and if the condition is met, the basic base station data is stored. For example: the wearable device detects whether a positioning data storage request sent by a control terminal associated with the wearable device is received, and if the positioning data storage request is received, the wearable device is determined to meet the condition of positioning and storing basic base station data; otherwise, if the data is not received, it is determined that the wearable device does not meet the condition of positioning and storing the basic base station data. By the implementation of the implementation mode, the storage space of the wearable device can be prevented from being occupied when the wearable device stores basic base station data.

Further, after the wearable device detects that a positioning storage request sent by a control terminal associated with the wearable device is received, the wearable device may further identify whether the positioning storage request includes unique identity data of the user, where the unique identity data of the control user may be physiological characteristic data (such as fingerprint data, iris data), a password, and the like of the control user; if the matching is successful, the wearable device determines that the positioning storage condition of the wearable device is met; if the matching is unsuccessful, it is determined that the location storage condition of the wearable device is not satisfied. Therefore, the wearable device can be subjected to positioning data storage only by a legal user who allows the wearable device to be controlled to perform positioning data storage and is registered in advance, and the phenomenon that the wearable device is subjected to positioning data storage and power consumption of the wearable device is increased due to the fact that the wearable device is subjected to positioning data storage by a control terminal of a user who allows the wearable device to be controlled to perform positioning data storage and is associated with other users but not registered in advance is prevented.

103. The wearable device controls the wearable device to carry out WIFI scanning so as to obtain target WIFI data.

The target WIFI data may include an ID, a signal strength, and the like of the target WIFI access point.

104. The wearable device judges whether the matching quantity of the target WIFI data and basic WIFI data exceeds a specified quantity, the basic WIFI data is WIFI data collected when the wearable device historically locates in the safe area, and if yes, step 105 is executed; if not, the flow is ended.

105. The wearable device stops executing the next positioning process for the wearable device.

As can be seen, with the power consumption control method of the wearable device described in fig. 1, when the matching number of the target WIFI data and the basic WIFI data obtained by scanning exceeds a specified number, the wearable device may consider that the wearable device is currently located in the secure area, and the corresponding wearable device may stop executing the next positioning process for the wearable device, so as to reduce power consumption when the wearable device applies the secure area guard reminding function.

In addition, by implementing the power consumption control method of the wearable device described in fig. 1, the number of times of acquiring the target base station data can be reduced, and the power consumption of the wearable device can be reduced.

In addition, by implementing the power consumption control method of the wearable device described in fig. 1, the workload caused by the need of periodically maintaining the stride information of different wearers when the wearable device stores the stride information of different wearers in advance is reduced.

201. the wearable device acquires target base station data, wherein the target base station data comprises base station data of current connection of the wearable device and surrounding base station data scanned by the wearable device.

In one embodiment, the wearable device may detect the skin temperature of the user prior to acquiring the target base station data, and, in general, the user is in a normal environment, the skin temperature of the user is stable, usually at a constant value, when the user suddenly accelerates the speed movement (such as suddenly escaping, waving arms or struggling), the skin of the user will have a certain temperature rise phenomenon, whether the wearable device is in a dangerous state (such as an escape state, an arm waving state and a struggle state) can be judged according to the duration of the skin warming, and if the skin temperature of the user exceeds a preset temperature threshold, the wearable device may control the wearable device to enter a countdown state, if the skin temperature of the user does not decrease after the wearable device countdown state ends, then it is determined that the current state of the user is unsafe and the wearable device performs the step of obtaining target base station data. Therefore, the times of acquiring the target base station data by the wearable device are effectively reduced, and the power consumption of the wearable device is reduced.

Further, after the skin temperature of the user rises, in order to dissipate heat as soon as possible, the skin usually dissipates heat by means of sweating and the like, so that the wearable device can further perform sweat detection on the skin contacted by the wearable device when the skin temperature of the user does not decrease after the countdown state of the wearable device is finished, if the skin contacted by the wearable device is detected to be in the sweating state, the wearable device controls the wearable device to enter the countdown state, if the sweating state of the user does not decrease after the countdown state is finished, it is determined that the current state of the user is unsafe, and the wearable device performs the step of acquiring the target base station data. Therefore, the times of acquiring the target base station data by the wearable device can be reduced more effectively, and the power consumption of the wearable device is reduced.

Furthermore, the skin temperature rise and the sweating state of the user may be that the user is performing normal exercise, the wearable device may detect whether two touch points (for example, two finger fingerprints) are identified by a touch display screen of the wearable device when the wearable device is in a countdown state, and if so, the step of the wearable device acquiring the target base station data is stopped, and the wearable device may effectively reduce power consumption increased by a security area guarding function when the user performs normal exercise.

204. The wearable device judges whether the number of the at least one target WIFI access point exceeds a specified number, if so, step 205 is executed, and if not, the process is ended.

205. The wearable device judges whether the average signal intensity corresponding to the at least one target WIFI access point obtained from the signal intensity corresponding to the at least one scanned target WIFI access point exceeds a specified signal intensity value, if yes, step 206 is executed; if not, the flow is ended.

206. The wearable device judges whether the matching quantity of the target WIFI data and basic WIFI data exceeds a specified quantity, the basic WIFI data is WIFI data collected when the wearable device historically locates in the safe area, if yes, step 207 is executed; if not, the flow is ended.

Wherein, wearable equipment judges whether the matching quantity of this target WIFI data and basic WIFI data exceeds the appointed quantity, can include:

and judging whether the matching number of the at least one target WIFI access point and the WIFI access points included in the basic WIFI data exceeds the specified number.

In an embodiment, after acquiring the basic WIFI data, the wearable device may generate a movement track of the wearable device according to a sequence of the acquired basic WIFI data, and after acquiring the target WIFI data, the wearable device determines whether the next acquired target WIFI data is the target WIFI data in the movement track, and if yes, executes step 207; if not, the flow is ended. The wearable device can effectively judge whether the wearable device deviates from a common moving track according to the acquired target WIFI data, so that the safety performance of the wearable device is improved.

207. The wearable device stops executing the next positioning process for the wearable device.

Therefore, by implementing the power consumption control method of the wearable device described in fig. 2, the power consumption of the wearable device when the secure area guard reminding function is applied can be reduced.

In addition, by implementing the power consumption control method of the wearable device described in fig. 2, the number of times that the wearable device acquires the target base station data can be effectively reduced, thereby reducing the power consumption of the wearable device.

In addition, by implementing the power consumption control method of the wearable device described in fig. 2, whether the wearable device deviates from a common movement track can be effectively judged according to the acquired target WIFI data, so that the safety performance of the wearable device is improved.

EXAMPLE III

Referring to fig. 3, fig. 3 is a schematic flow chart illustrating another power consumption control method of a wearable device according to an embodiment of the invention. As shown in fig. 3, the power consumption control method of the wearable device may include the steps of:

305. The wearable device obtains current GPS longitude and latitude data of the wearable device, wherein the current GPS longitude and latitude data comprise current GPS longitude and latitude coordinates.

In one embodiment, when the wearable device acquires the current GPS longitude and latitude data of the wearable device, GPS positioning needs to be started, after the GPS positioning is started, it may be determined whether the GPS positioning duration of the wearable device exceeds a preset first duration threshold, where the preset first duration threshold is a duration reached by the wearable device when the GPS positioning has no response, and if the GPS positioning duration exceeds the preset first duration threshold, the GPS positioning module is controlled to close the GPS positioning and send a message that the GPS positioning fails to the server, so that the GPS positioning is closed when the GPS cannot perform positioning, and power consumption of the GPS positioning is effectively reduced.

For example, the wearable device may set a preset first time threshold to be 1 minute, and after GPS positioning is started, if the GPS positioning is still in a no-response state when the GPS positioning time reaches 1 minute, the wearable device controls the GPS positioning module to close the GPS positioning, and sends a message that the GPS positioning fails to the server.

In one embodiment, when the wearable device acquires current GPS longitude and latitude data of the wearable device, GPS positioning needs to be started, after the GPS positioning is started, it may be determined whether the duration of the GPS positioning of the wearable device exceeds a preset second duration threshold, where the preset second duration threshold is a duration that is set by the wearable device and is reached when the wearable device does not respond to the GPS positioning because the wearable device is indoors, and where the preset second duration threshold is smaller than the preset first duration threshold, the GPS positioning module is controlled to close the GPS positioning, and a message indicating that the GPS positioning fails is sent to a server, and the GPS positioning is closed when the wearable device is indoors and the GPS cannot perform positioning, thereby effectively reducing power consumption of the GPS positioning.

For example, the wearable device may set the preset second duration threshold to be 30 seconds, after GPS positioning is started, if GPS positioning is not in a response state when the GPS positioning duration is started for 30 seconds, determine whether the wearable device is located indoors, and if the wearable device is located indoors, control the GPS positioning module to close the GPS positioning, and send a message that the GPS positioning fails to the server.

306. The wearable device calculates the distance between the current GPS longitude and latitude coordinates and each basic GPS longitude and latitude coordinate to obtain a distance set, and the basic GPS longitude and latitude data comprise at least one basic GPS longitude and latitude coordinate.

In one embodiment, the wearable device may calculate the distance between two points according to the longitude and latitude coordinates to obtain the distance between two longitude and latitude coordinates, and sum the distances to obtain a distance set.

307. The wearable device judges whether a target distance exists in the distance set, the target distance exceeds a preset maximum distance value, if yes, step 308 is executed; if not, go to step 309-step 310.

308. And the wearable device determines that the current GPS longitude and latitude data is not matched with the basic GPS longitude and latitude data, executes the next positioning process of the wearable device, and ends the process.

By implementing the above step 306 to step 309, the wearable device may determine whether the current GPS longitude and latitude data matches the basic GPS longitude and latitude data, where the basic GPS longitude and latitude data is the GPS longitude and latitude data collected by the wearable device when positioning is performed in the secure area historically.

310. The wearable device stops executing the next positioning process for the wearable device.

Therefore, by implementing the power consumption control method of the wearable device described in fig. 3, the power consumption of the wearable device when the secure area guard reminding function is applied can be reduced.

In addition, by implementing the power consumption control method of the wearable device described in fig. 3, the power consumption of GPS positioning can be effectively reduced.

In addition, by implementing the power consumption control method of the wearable device described in fig. 3, whether the wearable device is located indoors can be judged according to the WIFI signal strength and the GPS signal strength, so that power consumption caused by GPS positioning unresponsiveness due to the fact that the wearable device is located indoors is effectively reduced.

408. And the wearable device determines that the current GPS longitude and latitude data is not matched with the basic GPS longitude and latitude data, executes the next positioning process of the wearable device, and ends the process.

As an optional implementation, the wearable device performing a next positioning process on the wearable device may include: the wearable equipment is controlled to start the camera module, the camera module of the wearable equipment acquires the current image of the area where the wearable equipment is located, if the current image acquired by the wearable equipment is acquired, the image is automatically sent to the control terminal, and when the camera module of the wearable equipment acquires the current image, the GPS longitude and latitude of the area where the wearable equipment is located can be stored in the current image.

410. The wearable device stops executing the next positioning process for the wearable device.

In one embodiment, after the wearable device stops performing the next positioning process on the wearable device, the wearable device may detect whether the user wears the wearable device, and if the wearable device is not worn, the wearable device controls the wearable device to enter a deep sleep mode, where the deep sleep mode may control the wearable device to close all background applications (including a secure area guard function), preferably, the wearable device may receive external information in the deep sleep mode, such as a voice call sent by an external mobile device, and the wearable device may exit the deep sleep mode when detecting that the user wears the wearable device. When the user does not use the wearable device, all application programs in the background can be closed, external information can be received when the user enters the deep sleep mode, and the external information can be received while the power consumption is saved.

Therefore, by implementing the power consumption control method of the wearable device described in fig. 4, the power consumption of the wearable device when the secure area guard reminding function is applied can be reduced.

In addition, by implementing the power consumption control method of the wearable device described in fig. 4, the image of the current area and the GPS longitude and latitude can be automatically sent to the terminal control when the wearable device leaves the secure area, so that the wearable device can quickly send accurate and effective information to the control terminal when the wearable device leaves the secure area, thereby improving the security of the wearable device.

In an embodiment, before the first obtaining unit 501 obtains the target base station data, the wearable device may first determine whether a moving distance of the wearable device exceeds a specified safety distance, and if the moving distance exceeds the specified safety distance, the first obtaining unit 501 obtains the target base station data, so that the number of times of obtaining the target base station data may be reduced, and the power consumption of the wearable device may be reduced. For example, the wearable device determining whether the movement distance of the wearable device exceeds a specified safety distance may include:
