Along with the development of intelligent terminal technology, wearable equipment types are also abundant, and the use requirements of users in different scenes can be met. For example, the types of earphones include wired earphones, wireless bluetooth earphones, headsets, in-ear earphones, over-the-ear earphones, and the like. Wherein, wireless bluetooth headset receives user's favor more and more with its advantage such as nimble, portable, small and exquisite, but relatively, wireless bluetooth headset also leads to its easy problem of losing to appear because of its small and exquisite.

In contrast, a currently adopted scheme is to add a Global Positioning System (GPS) chip in the wireless bluetooth headset to assist the wireless bluetooth headset in positioning and retrieving. However, the installation of the GPS chip increases the cost of the wireless bluetooth headset, which increases the burden on the user. And, wireless bluetooth headset starts GPS chip location, increases its consumption, causes power consumption to increase, influences operating duration.

Disclosure of Invention

According to the Bluetooth headset loss prevention method and the electronic equipment, when the wireless Bluetooth headset is judged to be lost under the condition that a GPS chip is not installed on the wireless Bluetooth headset, the lost position of the wireless Bluetooth headset can be obtained by means of analysis of the electronic equipment connected with the wireless Bluetooth headset, the Bluetooth headset loss prevention method and the electronic equipment can be retrieved in an auxiliary mode, and loss is avoided.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, an embodiment of the present application provides a method for preventing a bluetooth headset from being lost, where the method may include: receiving an abnormal notification sent by the wearable device and/or meeting a first condition of communication quality between the wearable device and the received abnormal notification; the abnormal notification is a notification sent by the wearable device when the acceleration measurement value is determined to be matched with the gravity acceleration; the first condition comprises that the overtime quantity of the keep-alive messages is larger than or equal to a first threshold value, and/or the packet loss rate is larger than or equal to a second threshold value. The position information is recorded. With the location information, retrieval recommendations are obtained, the retrieval recommendations indicating a location area where the wearable device is lost.

For example, the wearable device can determine whether the acceleration measurement is the same as or similar to the acceleration of gravity using its own acceleration sensor. If the acceleration is the same or similar, determining that the acceleration is matched, enabling the wearable device to be in a free-fall state, sending an abnormal notification to the electronic device, notifying the abnormal state, and determining that the wearable device is in a lost scene by the electronic device through receiving the abnormal notification. And/or the electronic device and the wearable device communicate through wireless connection, and the signal transmission quality changes along with the change of the communication distance between the electronic device and the wearable device, and if the communication distance is larger, the communication quality is worse, and the electronic device judges that the wearable device is in a loss scene. The transmission quality can be measured by using the keep-alive heartbeat timeout quantity and/or the packet loss rate of the data packets transmitted between the electronic device and the wearable device.

As such, the electronic device determines whether the wearable device is in a lost scenario from the wearable device acceleration measurements and/or the communication quality. If the mobile terminal is in a lost scene, the electronic device may be used to record the location information, for example, the electronic device GPS may be used to record the location information. Then, based on the position information, through a big data analysis method, retrieving suggestions such as a lost position area and time of the wearable device are obtained, the user is helped to recall lost scenes, the user is assisted to retrieve the wearable device, and loss is avoided. Furthermore, the wearable device can be lost and recovered without adding a GPS chip in the wearable device, and the cost of the wearable device is reduced.

In one possible implementation manner, if an exception notification sent by the wearable device is received, recording the location information includes: the first location information is recorded at a first frequency. Determining that the communication quality between the wearable device and the user equipment meets a first condition, and recording second position information at a second frequency, wherein the second frequency is higher than the first frequency, and the position information comprises first position information and second position information.

For example, after the electronic device receives an exception notification sent by the wearable device, the GPS is started to record the electronic device location at frequency a. Then, if the communication quality is worse, the communication distance between the electronic device and the wearable device is increased, and the electronic device is far away from the wearable device. The loss probability of the wearable device becomes higher, the position information recording frequency of the electronic device is increased, for example, the position of a mobile phone is recorded by the frequency B, and B & gtA & gt 0. If the communication quality is not changed or becomes better after being degraded, the wearable device is not lost, and the recording of the position information is stopped.

Therefore, more effective position information is obtained by adjusting the position information recording frequency, so that more accurate retrieval suggestions can be obtained.

In one possible implementation, obtaining the retrieval suggestion using the location information includes: and sending the position information to a server. And receiving a retrieval suggestion, wherein the retrieval suggestion is determined by the server according to the position information.

The position information comprises the position recorded by the electronic equipment and a corresponding timestamp.

In some embodiments, the server receives the location information sent by the electronic device, and based on the location information, determines possible missing location area information for the wearable device. For example, after receiving the location information, the server determines the location area where the wearable device is lost in combination with a map. Further, the server can calculate the mobile phone moving speed and judge the user motion scene, such as walking, riding and the like, by using the position contained in the position information and the corresponding timestamp. And the scene of the user can be judged by combining the map and the moving speed. For example, the server determines that the user takes a bus and moves according to the moving speed, and determines that the moving track of the user is a certain bus route according to the map, so that the server can determine that the lost position may be a certain bus stop for taking a bus to go out when the user loses the wearable device. The lost location area of the wearable device can also be described as a lost location hotspot of the wearable device, a lost track hotspot of the wearable device, and the like. Optionally, after the electronic device completes recording of the location information, the electronic device may also directly perform local analysis and calculation by using the location information, determine a location area and a loss time that the wearable device may be lost, and generate an auxiliary retrieval suggestion.

So, electronic equipment can obtain the suggestion of getting back to for the user provides the suggestion of getting back, the wearable equipment of supplementary user getting back avoids losing.

In one possible implementation, after recording the location information, the method further includes: prompting that the wearable equipment is lost by a user in a preset reminding mode; the preset reminding mode comprises one or more of vibration reminding, voice broadcast reminding and notification message reminding.

Therefore, when the electronic equipment determines that the wearable equipment is in a lost scene and is possibly lost, the electronic equipment can prompt the user that the wearable equipment is lost abnormally through a preset reminding mode, and the user can timely retrieve the wearable equipment after receiving the reminding to avoid loss.

In one possible implementation, before obtaining the retrieval suggestion using the location information, the method further includes: a first connection disconnection with the wearable device is determined. The recording of the position information is stopped.

In some embodiments, the electronic device begins recording location information until after the electronic device is disconnected from the wearable device, the recording is stopped. In the process of recording the location information, the electronic device may use a last received signal (i.e., a disconnection signal) as a loss confirmation signal, and the recorded location information should include location information when the electronic device and the wearable device are disconnected.

Therefore, the server can determine the possible loss range of the wearable device by utilizing the position and the timestamp during disconnection in the process of determining the auxiliary recovery suggestion, so that the lost position area of the wearable device is increased, and the accuracy of position area determination is improved. Furthermore, after the disconnection is determined, the electronic equipment can automatically turn off the GPS, does not record the position information any more, and can save power consumption while providing the position information.

In one possible implementation, the method further comprises: and displaying a first interface, wherein the first interface is used for displaying the retrieval suggestion. A location area where the wearable device is missing is determined. Searching for a first signal sent by the wearable device according to a preset period, wherein the first signal is a signal sent by the wearable device in a low-power-consumption mode, and the first signal is used for representing that the wearable device is to be connected. Based on the first signal, a second connection is established with the wearable device.

In some embodiments, after the wearable device is disconnected from the electronic device, the low power consumption mode needs to be started, and the service and hardware functions of the wearable device need to be closed, so that the power consumption is reduced, the electric quantity is saved, the standby time is prolonged, and the recovery probability is improved. The wireless communication module is started to send the broadcast signal only according to the preset period, so that the electronic equipment can find the wearable equipment conveniently.

In some embodiments, the electronic device receives an assisted recovery suggestion sent by the server. And then, the electronic equipment detects that the user starts the operation of retrieving the wearable equipment function, and then displays an auxiliary retrieving suggestion, guides the user to determine the lost position area of the wearable equipment, and helps the user to recall the possible lost position.

And then, the electronic equipment searches for the broadcast signal sent by the wearable equipment according to a preset period, and the electronic equipment is paired with the wearable equipment again to establish wireless connection. After the wireless connection is established, a specific location of the wearable device is found based on the wireless connection. For example, based on the wireless connection, the wearable device is controlled to emit sound so that the user discovers the wearable device. So, realize getting for back of wearable equipment, avoid losing.

In the description of the embodiments of the present application, the meaning of "a plurality" means two or more unless otherwise specified. "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

Fig. 1 is a schematic diagram of a communication system to which a bluetooth headset loss prevention method according to an embodiment of the present invention is applied. As shown in fig. 1, the communication system includes a wearable device 100 and an electronic device 200.

For example, the wearable device 100 may be a wireless headset, a smart watch, a smart bracelet, or smart glasses, among others. The electronic device 200 may be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a Personal Digital Assistant (PDA), a desktop, a laptop, a handheld computer, a vehicle-mounted terminal, an artificial intelligence (artificial intelligence) device, and the like, and the specific forms of the wearable device 100 and the electronic device 200 according to the embodiment of the present disclosure are not limited at all.

The wearable device 100 may establish a wireless connection with the electronic device 200 through wireless communication technology. The wireless communication technology may include Bluetooth (BT) (e.g., conventional bluetooth or low energy BLE bluetooth), Wireless Local Area Network (WLAN) (e.g., wireless fidelity (Wi-Fi) network), Zigbee, Frequency Modulation (FM), Near Field Communication (NFC), infrared (infrared, IR), or general 2.4G/5G band wireless communication technology.

The embodiment of the present application takes a wireless communication technology as an example for explanation. After the wearable device 100 and the electronic device 200 establish bluetooth connection, the wearable device 100 and the electronic device 200 may determine a connection status of the other party by transmitting keep-alive messages to each other. For example, the electronic device 200 sends a keep-alive message to the wearable device 100, and starts a timer, and if the electronic device 200 receives a keep-alive response message returned by the wearable device 100 within a preset time, it is determined that the connection state is good; if the keep-alive response message is received beyond the preset time, determining that the connection signal is poor; and if the keep-alive response message is not received, determining that the connection is disconnected.

In some embodiments, there is a working distance limit after the wearable device 100 and the electronic device 200 are connected via bluetooth. For example, after the distance between the wearable device 100 and the electronic device 200 exceeds 20 meters, the interaction signal gradually decreases to be completely disconnected as the distance increases. If the user does not currently find the wearable device 100 to be abnormally disconnected, a loss problem may occur. It is understood that the bluetooth chip in the wearable device 100 and the electronic device 200 have different working performance and working distance, for example, the working distance is 10 meters, 20 meters, 50 meters, etc. Beyond the working distance, the wearable device 100 automatically disconnects bluetooth from the electronic device 200.

In some embodiments, a first Application (APP) is installed in the electronic device 200 for finding the wearable device 100 connected to the electronic device 200, and preventing the wearable device 100 from being lost. The first application is, for example, finding an APP, preventing loss of an APP, or the like.

In some scenarios, when an Acceleration (ACC) sensor in the wearable device 100 determines that the acceleration of the wearable device is the same as or similar to the acceleration of gravity, it determines that the wearable device is falling freely and is in a falling scene. Wearable device 100 sends a signal to electronic device 200, and after receiving the signal, the first application starts GPS for location recording until electronic device 200 moves beyond the bluetooth working distance between wearable device 100 and electronic device 200 to disconnect. Thereafter, the electronic device 200 analyzes the recorded location information, determines a lost location of the wearable device 100, and assists the user in retrieving the wearable device 100. Optionally, the electronic device 200 may also notify the user that the wearable device 100 may be lost at the same time of recording the location, and prompt the user to retrieve the wearable device 100 in time, so as to reduce the possibility of loss.

In other scenarios, the wearable device 100 and the electronic device 200 transmit the keep-alive messages, and when the timeout times of the keep-alive messages increase, the first application starts the GPS to record the location until the connection is disconnected after exceeding the working distance. The electronic device 200 can thus obtain the lost position of the wearable device 100 by analyzing the position information, preventing the wearable device 100 from being lost.

In some embodiments, as shown in fig. 1, the communication system described above may also include a server 300. The electronic device 200 may transmit the recorded location information to the server 300. The server 300 analyzes the data and determines the location area where the wearable device 100 is lost.

The audio module 105 is used to convert digital audio information into an analog audio signal output and also to convert an analog audio input into a digital audio signal. The audio module 105 may also include an encoder and a decoder for encoding and decoding an audio signal. In some embodiments, the audio module 105 may be disposed in the processor 101, or some functional modules of the audio module 105 may be disposed in the processor 101.

In some embodiments, electronic device 200 may control wearable device 100 to emit sound with audio module 105 through the first application so that the user can find a specific location of wearable device 100 through voice guidance.

An Acceleration (ACC) sensor 106 may detect the magnitude of acceleration of wearable device 100 in various directions (typically three axes). In some embodiments, the processor 101 obtains the acceleration detected by the acceleration sensor 106, determines that the current acceleration is the same or similar to the acceleration of gravity, determines that the wearable device 100 is currently falling, and sends a notification message to the electronic device 200 using the wireless communication module 103. The electronic device 200 can thus determine that the wearable device 100 may be in a lost scenario based on the notification message, initiating GPS to begin recording location information.

In the following embodiments, a bluetooth headset is taken as the wearable device 100, and a mobile phone is taken as the electronic device 200 for example. The bluetooth headset includes, for example, a wireless bluetooth headset.

In some scenarios, the mobile phone has a retrieving function, which can be used to retrieve other devices connected thereto. For example, after the mobile phone is connected with the bluetooth headset, when the user cannot find the bluetooth headset, the bluetooth headset can be found by using the finding function in the mobile phone. Optionally, the function of finding back the mobile phone can be realized by using the first application, for example, finding the APP, preventing the APP from being lost, and the like.

Illustratively, as shown in the main interface 401 in fig. 4 (a), after the mobile phone detects an operation of clicking the find APP icon 41 by the user, the find APP is started, and an interface 402 shown in fig. 4 (b) is displayed for displaying one or more devices that establish a connection with the mobile phone, such as a connection with a bluetooth headset. The handset detects the operation of the user clicking on the bluetooth headset control 42, and the interface 403 shown in fig. 5A is displayed. After detecting the operation of clicking the play sound control 43 by the user on the interface 403, the mobile phone makes a "click" prompt sound with the bluetooth headset 44, so that the user can find the bluetooth headset 44 conveniently.

So, the cell-phone realizes that bluetooth headset retrieves through the initiative sound production of first application control bluetooth headset, avoids losing. However, in the current solution, the handset and the bluetooth headset must be connected to each other, so that the bluetooth headset can be controlled to sound through the wireless connection. However, in general, when a user finds that the bluetooth headset is lost, the bluetooth headset is disconnected from the mobile phone, and cannot be retrieved by using the current scheme, so that the loss probability is high.

In other scenes, a GPS chip is installed in the Bluetooth headset, and the Bluetooth headset reports the position information of the Bluetooth headset to the mobile phone in real time or periodically by using the GPS chip. Then after the bluetooth headset is lost, the mobile phone can provide the user with a history of the location information of the bluetooth headset, thereby helping the user to retrieve the bluetooth headset.

Illustratively, as shown in (B) of fig. 4, interface 402 collects operations of detecting a user clicking on the bluetooth headset control 42, and displays interface 404 shown in fig. 5B. The interface 404 includes a display area 4041 and a display area 4042, where the display area 4041 is used to display a function control corresponding to the bluetooth headset, and the display area 4042 is used to display position information of the bluetooth headset. For example, after the mobile phone detects the user's operation of clicking the pointing device control 45, the location of the bluetooth headset, such as location a, is displayed in the display area 4042. Optionally, if the mobile phone is connected to the bluetooth headset, the position a is a real-time position of the bluetooth headset, and if the mobile phone is disconnected from the bluetooth headset, the position a is a last position before the bluetooth headset is disconnected.

Therefore, even if the mobile phone is disconnected with the Bluetooth headset, the user can also find the headset through the position information reported by the Bluetooth headset. However, adding a GPS chip to a bluetooth headset increases the cost of the bluetooth headset. Secondly, the bluetooth headset needs to report the position information in real time or periodically, and the working power consumption of the GPS chip is large, which results in the increase of the power consumption of the bluetooth headset. Moreover, the volume of the Bluetooth headset is small, the capacity of a battery is limited, the working time of the Bluetooth headset after charging every time is limited, and the use experience of a user is influenced by the increase of the charging times. Furthermore, after the Bluetooth headset is lost, the Bluetooth headset still can continuously send position information, the residual power is exhausted in a short time, and the retrieving difficulty is increased.

Based on this, the embodiment of the application provides a method for preventing a bluetooth headset from being lost, a GPS chip does not need to be installed in the bluetooth headset, and when the mobile phone and/or the bluetooth headset judge that the bluetooth headset is in a lost scene, the mobile phone and/or the bluetooth headset can record position information by calling the GPS chip in the mobile phone, so as to help a user to find back the bluetooth headset and avoid loss.

In some scenes, an ACC sensor is installed in the Bluetooth headset and used for measuring self acceleration, and the Bluetooth headset can judge the reason of the change of the current acceleration according to the measured value of the acceleration. For example, the bluetooth headset can determine, from the acceleration measurement, whether the increase in the current acceleration is due to an operation of the user to remove the bluetooth headset or due to the bluetooth headset being dropped. For example, the bluetooth headset measures a sudden increase in current acceleration to match the acceleration of gravity (e.g., the same or similar to the acceleration of gravity), e.g., an acceleration measurement of 9.8m/s². And then, if the acceleration is changed into 0, judging that the current Bluetooth headset falls off and possibly losing abnormity. Then, the bluetooth headset sends the current abnormal condition to the mobile phone, and the mobile phone further judges whether the current scene is a bluetooth headset loss scene. Among them, an ACC sensor is generally provided in a bluetooth headset for drop detection. If the Bluetooth headset falls, the ACC sensor can be used for detecting the falling scene, and the mobile phone is informed of pausing the audio function corresponding to the Bluetooth headset currently, such as pausing music playing. Therefore, measuring acceleration with an ACC sensor does not increase the cost of the bluetooth headset.

It should be noted that the bluetooth headset missing scene includes a monaural missing scene and a binaural missing scene. The method for preventing the Bluetooth headset from being lost provided by the embodiment of the application is described by taking a single-ear loss scene as an example, and the scenes that two ears are lost are not repeated.

For example, as shown in fig. 6, during walking, the bluetooth headset 61 is abnormally dropped at the position a (e.g., the ground), and during dropping of the bluetooth headset 61, the ACC sensor in the bluetooth headset 61 measures the self-acceleration and determines that the current acceleration matches the acceleration due to gravity. After that, upon falling at the position a, the ACC sensor in the bluetooth headset 61 measures that the self acceleration becomes 0. At this time, there are at least two cases. In one case, the user finds the bluetooth headset dropped and picks up the headset. In the present situation, the ACC sensor in the bluetooth headset 61 measures the change of the self acceleration, and then it is determined that the bluetooth headset is not in the loss scene. Alternatively, the user does not find the bluetooth headset dropped and continues to move forward (as in position B) in the direction of arrow 62. The ACC sensor in the bluetooth headset 61 measures that the self acceleration is unchanged within a first preset time period, and if the acceleration value is kept to be 0 within X seconds, and X is greater than 0, it is determined that the bluetooth headset is in a lost scene. It should be understood that in the scenario shown in fig. 6, the user should move while carrying the mobile phone during the movement process, which is not described below.

In some embodiments, the bluetooth headset sends an exception notification to the mobile phone, and after receiving the exception notification, the mobile phone determines whether the bluetooth headset is in a loss scene. Optionally, when the bluetooth headset judges that the self acceleration is matched with the gravitational acceleration, an abnormal notification is sent to the mobile phone, then the bluetooth headset sends an acceleration value to the mobile phone in real time, the mobile phone monitors the acceleration change condition of the bluetooth headset, analyzes whether the bluetooth headset is in a lost scene, and reduces the power consumption of the bluetooth headset for judging the lost scene. Or after the Bluetooth headset determines that the acceleration value of the Bluetooth headset is matched with the gravity acceleration and is subsequently changed into 0, the Bluetooth headset sends an abnormal notification to the mobile phone. Or the Bluetooth headset sends an abnormal notification to the mobile phone after determining that the acceleration value of the Bluetooth headset is changed from being matched with the gravity acceleration to 0 and is kept to be 0 in the first time period, so that misjudgment is avoided.

In some embodiments, after receiving the abnormal notification, the mobile phone reminds the user that the current bluetooth headset may be lost through a preset reminding mode. If the mobile phone receives the abnormal notification sent by one Bluetooth headset and judges that the other Bluetooth headset is working normally, the normally working Bluetooth headset can be used for sounding to notify the user that the Bluetooth headset is lost. If the voice broadcast 'please notice that the bluetooth headset may be lost, please confirm'. If the mobile phone receives the abnormal notification sent by one Bluetooth headset and judges that the other Bluetooth headset does not work normally (if the other Bluetooth headset is not started), or if the mobile phone receives the abnormal notification sent by the two Bluetooth headsets, the mobile phone is used for reminding a user that the Bluetooth headset is abnormal in loss. The preset reminding mode comprises one or more of vibration reminding, voice broadcast reminding and notification message reminding.

For example, as shown in a notification interface 701 in fig. 7, after the mobile phone receives the abnormal notification, a prompt box 71 is displayed to prompt the user that the bluetooth headset may be lost.

From this, through the acceleration that bluetooth headset detected, the cell-phone judges whether bluetooth headset freely falls and drops, and if bluetooth headset freely falls, the cell-phone reminds user bluetooth headset to lose unusually through the aforesaid warning mode of predetermineeing, and the user receives this warning back, can in time find back bluetooth headset, avoids losing.

In some scenarios, after the mobile phone reminds the user through a preset reminding mode, the user may not obtain the reminding in time, and then the mobile phone may generate an auxiliary retrieving suggestion to help the user retrieve the bluetooth headset when finding that the bluetooth headset is lost.

In some embodiments, after receiving the abnormal notification, the first application in the mobile phone starts the GPS to start position recording and record time at the same time, so as to facilitate subsequent analysis of the position and time lost by the bluetooth headset. Optionally, the recording duration is preset, and after the mobile phone receives the exception notification, the mobile phone records the mobile location information and time of the mobile phone within the preset recording duration (e.g., N seconds). Or after the mobile phone receives the abnormal notification, the mobile phone starts to record the position information and the time of the mobile phone until the mobile phone is disconnected with the Bluetooth headset, and then the recording is stopped. In the process of recording the position information, the mobile phone can use the last received signal (namely, the disconnection signal) as a loss confirmation signal, and the recorded position information should include the position information when the mobile phone and the bluetooth headset are disconnected.

In some embodiments, after the mobile phone completes recording the location information by using the GPS, the location information and the corresponding time information are sent to the cloud server. And the cloud server performs data analysis by using the received position information and the time information, determines the lost position area and the lost time of the Bluetooth headset, and generates an auxiliary retrieving suggestion. The location area where the bluetooth headset is lost may also be described as a location hot area where the bluetooth headset is lost, a track hot area where the bluetooth headset is lost, or the like. Optionally, after the mobile phone completes recording the position information, the mobile phone may also directly perform local analysis and calculation by using the position information, determine a lost position area and lost time of the bluetooth headset, and generate an auxiliary retrieving suggestion.

Illustratively, after receiving the position information and the time information, the cloud server determines a position area where the bluetooth headset is lost by combining a map. Furthermore, the cloud server can calculate the mobile speed of the mobile phone by utilizing the position information and the time information, and judge the motion scenes of the user, such as walking, riding and the like. And the scene of the user can be judged by combining the map and the moving speed. As shown in fig. 8, the cloud server determines that the user takes a bus and moves according to the moving speed, and determines that the moving track of the user is a certain bus route according to the map, so that it can be determined that the lost position may be a certain bus stop for taking a bus to go out when the user loses the bluetooth headset 81.

In other embodiments, the mobile phone can also determine the GPS position recording frequency according to the self moving speed. For example, the mobile phone may record the location information using a low frequency when determining that the mobile speed is between 4km/h and 6km/h and determining that the user is walking. For another example, if the mobile phone determines that the user is moving by a car based on the moving speed, it is necessary to record the position information at a high frequency. Then, more effective position information can be obtained, and then the lost position area of the Bluetooth headset can be determined more accurately.

Therefore, after the Bluetooth headset is lost, the position information can be recorded by using a GPS in the mobile phone connected with the Bluetooth headset, and the lost position area of the Bluetooth headset can be determined by analyzing the position information. And then follow-up when the user gets back bluetooth headset, can utilize position information, help the user to remember the possible position of losing, get back bluetooth headset, avoid the loss.

For example, after discovering that the bluetooth headset is lost, the user may retrieve the lost bluetooth headset using the first application. As shown in the interface 402 in (b) of fig. 4, after the mobile phone detects the operation of clicking the bluetooth headset control 42 by the user in the first application, the interface 901 shown in (a) of fig. 9 is displayed. After detecting the operation of the user clicking the loss retrieving control 91, the mobile phone displays an interface 902 as shown in fig. 9 (b). Interface 902 is used to display assistance recovery suggestions, such as including lost location information, lost time, etc. For example, the assisted recovery recommendation as shown in interface 902 includes a bluetooth headset lost area and a corresponding time. The area A is a central area and is used for representing the maximum probability loss position of the Bluetooth headset. Optionally, the central point (the position shown as the mark 92) of the area a is the position where the acceleration changes to 0 after the acceleration measured by the bluetooth headset is matched with the acceleration of gravity, that is, the initial position recorded when the GPS is started. The area B is used for representing a possible loss area of the Bluetooth headset; and the area C is a recorded mobile phone moving position area after the Bluetooth headset is disconnected with the mobile phone. And then, the mobile phone can provide a navigation function for the user to help the user to plan and retrieve the route.

In some embodiments, the mobile phone and the bluetooth headset communicate through the bluetooth connection, and the signal transmission quality may change as the communication distance between the mobile phone and the bluetooth headset changes, for example, the larger the communication distance is, the worse the communication quality is. The transmission quality can be measured by using the keep-alive heartbeat timeout quantity and/or the packet loss rate of the data packets transmitted between the mobile phone and the Bluetooth headset. If the number of keep-alive heartbeat overtime and/or the packet loss rate of the data packet increases, it indicates that the transmission quality is deteriorated, and then it is determined that the communication distance increases. After the mobile phone receives the abnormal notification sent by the Bluetooth headset, the GPS is started to record the position of the mobile phone by the frequency A. If the communication quality is not changed or becomes better after being degraded, it indicates that the bluetooth headset is not lost, and the recording of the position information is stopped. If the communication quality is worse and worse, the communication distance between the mobile phone and the Bluetooth headset is increased, and the mobile phone is far away from the Bluetooth headset. The loss probability of the Bluetooth headset becomes higher, the position information recording frequency of the mobile phone is increased, and if the position of the mobile phone is recorded by the frequency B, B is more than A and more than 0. Furthermore, in the scene that the wearable device is lost is judged by using the communication quality at present, an ACC sensor does not need to be configured in the Bluetooth headset, and the electronic device can judge that the Bluetooth headset is in the lost scene so as to reduce the cost of the Bluetooth headset. Or, the ACC sensor is configured in the Bluetooth headset, but the wearable device is judged to be in a lost scene by the electronic device based on the communication quality, so that the working power consumption of the ACC sensor of the Bluetooth headset can be reduced, and the power consumption is reduced. Or, an ACC sensor is configured in the Bluetooth headset, the Bluetooth headset measures acceleration by using the ACC sensor, and then the electronic device judges that the Bluetooth headset is in a lost scene based on the acceleration measurement value and the communication quality of the Bluetooth headset, so that the accuracy of judging the lost scene is improved.

For example, as shown in fig. 6, the bluetooth headset 61 is left at the position a, the mobile phone moves in the direction indicated by the arrow 62, and the number of heartbeat timeouts and/or the packet loss rate increase during the moving process, and exceeds the preset threshold when moving to the position B. During the movement from position a to position B, the handset records the handset position at frequency a. And then, the mobile phone continues to move, the keep-alive heartbeat timeout quantity and/or the packet loss rate of the data packet gradually increase, the mobile phone moves to the position C along the direction indicated by the arrow 63, and the mobile phone is disconnected from the Bluetooth headset. And recording the position of the mobile phone at the frequency B during the movement from the position B to the position C.

Also exemplarily, corresponding to the scenario shown in fig. 6, as shown in an interface 902 (B) in fig. 9, the area a corresponds to the mobile phone moving position information from the position a to the position B, the area B corresponds to the mobile phone moving position information from the position B to the position C, the area C is the position information recorded within a second after the mobile phone and the bluetooth headset are disconnected from the position C, and a > 0. Further, the position indicated by the mark 93 is the position of the position C shown in fig. 6, that is, the position where disconnection is confirmed.

In other scenes, the bluetooth headset is lost by the user in a certain place, and the bluetooth headset cannot fall freely at the moment, namely the lost scene cannot be judged by using the acceleration. At this time, whether the bluetooth headset is in a lost scene can be directly judged by using the communication quality.

Illustratively, the mobile phone receives the timeout of the keep-alive messages (or the messages are described as periodic heartbeats) sent by the Bluetooth headset periodically, and the timeout quantity is increased; and/or the packet loss rate of the data packet transmitted between the mobile phone and the Bluetooth headset is increased. At the moment, the mobile phone starts a first application, and the first application starts a GPS to start recording the mobile position information of the mobile phone.

In some embodiments, the mobile phone starts to record the location information when determining that the keep-alive message is timed out. Or, when the mobile phone determines that the number of the keep-alive messages exceeds a threshold i and/or the packet loss rate exceeds a threshold j, the mobile phone starts to record the mobile position. Wherein i and j are greater than zero.

In some embodiments, when the mobile phone determines that the number of keep-alive messages exceeds the time limit and/or the packet loss rate increases, a preset reminding mode is adopted to remind the user that the bluetooth headset may be lost. Such as a vibration of the phone and/or a sound, and/or the user is notified by way of a notification message via the interface 701 as shown in fig. 7.

In some embodiments, the mobile phone records the location information with a frequency a, and if the number of keep-alive messages overtime and/or the packet loss rate continues to increase, the location information recording frequency is increased, for example, the location is recorded with a frequency B, where B > a > 0. If the number of the keep-alive messages is overtime and/or the packet loss rate is reduced, the position information recording frequency can be reduced, if the position is recorded by the frequency C, A is more than C and is more than 0. When the number of keep alive messages is over time and/or the packet loss rate is continuously reduced to 0, the recording of the position information can be stopped, and the situation that the current Bluetooth headset is not lost is judged.

Therefore, the mobile phone and the Bluetooth headset judge whether the Bluetooth headset is in a loss scene or not through the acceleration measured value and/or the communication quality of the Bluetooth headset. If the Bluetooth headset is in a lost scene, the GPS in the mobile phone is used for recording position information, and the lost position information and the lost time information of the Bluetooth headset are obtained through a big data analysis method, so that the user can be helped to recall the lost scene, and the user can be assisted to find the Bluetooth headset. Therefore, the Bluetooth headset can be lost and recovered without adding a GPS chip in the Bluetooth headset, the cost of the Bluetooth headset is reduced, and the problem that the power consumption of the Bluetooth headset is increased due to the real-time reporting of the position information is solved.

In some scenarios, the bluetooth headset is small and has a limited battery capacity, resulting in a limited operating time after each charging. If the bluetooth headset is lost and keeps a normal working state, the bluetooth headset may be powered off after the power consumption is exhausted before the user finds the bluetooth headset, and the retrieving difficulty is increased. Therefore, after the Bluetooth headset is determined to be lost, the Bluetooth headset can start a low power consumption mode, and power consumption is reduced. Optionally, after determining to disconnect from the mobile phone, the bluetooth headset may start the low power consumption mode. The low power consumption mode may also describe a silent mode, a low frequency mode, a full silent-low frequency discovery mode, etc.

In some embodiments, services and hardware functions associated with detectability are periodically enabled after the bluetooth headset initiates the low power mode, and other services and hardware functions remain off. For example, as shown in fig. 2, the bluetooth headset turns off non-detectability-related services and hardware functions such as an audio module for implementing an audio function, a storage module for implementing a storage function, and the like, and only periodically starts the wireless communication module related to detectability to perform signal broadcasting for informing other devices that the bluetooth headset is currently in a connectable state. And if the reconnection is successful within the preset time, exiting the low power consumption mode and starting normal operation. If reconnection fails within the preset time length, the low power consumption mode is kept, all service and hardware functions are closed, and the wireless communication module related to detectability is started in the next period to continue to send broadcast signals. For example, the bluetooth headset wakes up every X minutes, and broadcasts a signal for reestablishing a bluetooth connection with the mobile phone. And after Y seconds, if the mobile phone is not reconnected with the mobile phone, the mobile phone enters the low power consumption mode again, and wakes up again after waiting for X minutes to broadcast signals. Wherein X and Y are both greater than zero.

In some embodiments, such as the scenario shown in fig. 9, the handset guides the user to the bluetooth headset lost location area using an assisted recovery recommendation. Then, the mobile phone starts the Bluetooth function, searches the broadcast signal of the Bluetooth earphone and tries to connect. It will be appreciated that the search duration should be greater than the period duration, e.g., greater than X minutes, during which detectably relevant services and hardware functions are woken up in the bluetooth headset low power mode.

And then, the mobile phone and the Bluetooth headset reestablish Bluetooth connection. As shown in the interface 402 in (b) of fig. 4, the first application is launched by the mobile phone, and after detecting that the user clicks the bluetooth headset control 42, the interface 901 shown in (a) of fig. 9 is displayed. After the operation that the user clicks the playing sound control 94 is detected, the Bluetooth headset is controlled to send out a click prompt tone, so that the user can conveniently confirm the specific position of the lost Bluetooth headset and find the lost Bluetooth headset, and the loss is avoided.

So, through starting low power consumption mode, it is long when increasing bluetooth headset standby, ensure that bluetooth headset can possess more time after losing and be given for change, increase the probability of giving for change, further avoid bluetooth headset to lose.

Fig. 10 is a schematic flowchart of a method for preventing a bluetooth headset from being lost according to an embodiment of the present disclosure. Referring to FIG. 10, the method includes S1001-S1009.

S1001, the wearable device determines that the acceleration is matched with the gravity acceleration.

S1002, the wearable device sends an abnormal notification to the electronic device.

In some embodiments, in the above steps S1001 and S1002, the bluetooth headset is connected to the wearable device via bluetooth, the ACC sensor in the wearable device measures a self-acceleration, and if it is determined that the self-acceleration is the same as or similar to the gravitational acceleration, it is determined that the wearable device is in a free-fall state and may be lost, and an abnormal notification is sent to the electronic device connected to the wearable device to notify the electronic device of the abnormal state of the wearable device. Or after the wearable device determines that the self acceleration is the same as or similar to the gravity acceleration, the self acceleration becomes 0, and then an abnormal notification is sent to the electronic device connected with the wearable device, so as to notify the electronic device of the abnormal state of the current wearable device.

S1003, the electronic equipment records position information and prompts the user that the wearable equipment is lost possibly in a preset reminding mode.

In some embodiments, after receiving the exception notification, the first application in the electronic device activates the GPS to start recording the electronic device location information. The first application is an application program used for managing or searching the wearable device in the electronic device. The position information includes time information corresponding to the recording position. As at time a, position 1 is reached; time B, arrival at position 2, etc. Furthermore, the electronic equipment prompts a user that the wearable equipment is possibly lost through one or more prompting modes of vibration prompting, voice broadcast prompting and notification message prompting.

So, the user can in time confirm whether wearable equipment loses according to the suggestion, avoids wearable equipment to appear losing unusually.

In some embodiments, after the electronic device starts the GPS, the electronic device collects the location information with a lower frequency, and if the acceleration of the wearable device is still zero, it is determined that the wearable device is actually in a lost scene, and the collection frequency of the location information is increased. And then, judging that the distance between the wearable device and the user equipment is increased by utilizing the communication quality, and continuously increasing the acquisition frequency of the position information.

In some embodiments, the electronic device may change the location information collection frequency according to its location change speed. For example, if the user is moving on foot and the electronic device determines that the current movement speed is slow, the electronic device may collect location information with a low frequency. For another example, when the user is moving by a car and the electronic device determines that the current moving speed is fast, the electronic device needs to acquire the position information at a high frequency. Thereby guarantee before disconnected with wearable equipment, can gather more positional information, generate more accurate supplementary suggestion of finding back, and then improve the possibility that the user found back wearable equipment.

In some embodiments, the user may not be concerned with or receive the reminder, and then the auxiliary retrieval suggestion needs to be generated through the following steps, so as to help the user to determine the lost position more quickly in the subsequent process of finding the wearable device, and improve the possibility of retrieving the wearable device.

S1004, the Bluetooth connection between the electronic device and the wearable device is disconnected.

In some embodiments, the bluetooth connection has a communication distance (or may be described as a working distance) limitation, and in the process of recording the position information of the movement of the electronic device, due to the movement of the electronic device, the distance between the electronic device and the wearable device may become larger and larger, which results in exceeding the bluetooth communication distance, and if the signal sent by the wearable device cannot be received, the bluetooth connection is disconnected from the wearable device. For example, within a preset time period after the electronic device receives a certain signal sent by the wearable device, the electronic device does not receive the next signal, and then determines that the connection state between the electronic device and the wearable device is abnormal, closes the local bluetooth adapter, and disconnects the bluetooth connection. For another example, if the distance between the electronic device and the wearable device is greater than the distance threshold, and the electronic device signal is read abnormally, it is determined that the I/O interface is abnormal, and the bluetooth connection is disconnected. The electronic device determines that the Bluetooth connection is disconnected, and determines that the current wearable device loss scene is a valid loss scene, namely, it is determined that the wearable device is lost. The following step S1005 is performed to transmit the location information to the server. Accordingly, the wearable device can also determine that the bluetooth connection is disconnected by using the above method, and then execute the following step S1006 to start the low power consumption mode.

It is understood that the electronic device and the wearable device may also determine the disconnection state of the bluetooth connection in other manners, and the embodiment of the present application is not particularly limited.

S1005, the electronic device sends the recorded location information to the server.

In some embodiments, after determining that the wearable device is disconnected from the wearable device by the method in step S1004, the electronic device stops recording the location information (for example, automatically turns off the GPS), and sends all the recorded location information to the server for analysis. Optionally, the location information sent by the electronic device to the server includes location information at the disconnection time. Or after the electronic equipment is determined to be disconnected from the wearable equipment, the position information of the preset time length is recorded, and all recorded position information is sent to the server for analysis.

In some embodiments, the electronic device may package and send the recorded location information to the server, the location information including, for example, the location of the record and a corresponding timestamp.

And S1006, the wearable device starts a low power consumption mode and broadcasts a signal according to a preset period.

In some embodiments, after the wearable device is disconnected from the electronic device by the method in step S1004, the low power consumption mode needs to be started, and the service and hardware functions of the wearable device need to be shut down, so as to reduce power consumption, save electric power, increase standby time, and improve the recovery probability. The wireless communication module is started to send the broadcast signal only according to the preset period, so that the electronic equipment can find the wearable equipment conveniently.

In other embodiments, after completing the recording of the location information, the electronic device may not send the recorded location information to the server, and may process the recorded location information by using its own processing module to generate an auxiliary retrieval suggestion.

It should be noted that, in the embodiment of the present application, the execution sequence of the above step S1005 and step S1006 is not specifically limited. For example, after the bluetooth connection between the electronic device and the wearable device is disconnected, the wearable device starts a low power consumption mode while the electronic device sends the recorded location information to the server, and broadcasts a signal according to a preset period.

S1007, the server generates an auxiliary recovery suggestion.

In some embodiments, the server receives the location information sent by the electronic device, and based on the location information, determines possible missing location area information for the wearable device. For example, as shown in the interface 902 in fig. 9 (b), the server determines the lost positions of the wearable device with different probabilities by using the position and the timestamp included in the position information, and generates the auxiliary recovery suggestion. The position containing the maximum probability loss of the wearable device is the area A if the auxiliary recovery suggestion is included, and the position corresponding to the area A and the specific time are included.

S1008, the server sends the auxiliary retrieving suggestion to the electronic device.

S1009, displaying an auxiliary retrieving suggestion and assisting the user in retrieving the wearable device.

In some embodiments, the electronic device receives an assisted recovery suggestion sent by the server. Thereafter, the electronic device detects that the user initiates an operation to retrieve the wearable device function, and displays an auxiliary retrieval suggestion, such as an interface 902 shown in fig. 9 (b). As shown at 10: 00, the electronic equipment is located on the XXX path, and guides the user to determine the lost position area of the wearable equipment and helps the user to remember possible lost positions.

And then, the electronic equipment searches for the broadcast signal sent by the wearable equipment according to a preset period, and the electronic equipment is paired with the wearable equipment again to establish Bluetooth connection. After the bluetooth connection is established, based on the bluetooth connection, look for the specific location of wearable device. For example, based on the bluetooth connection, the wearable device is controlled to sound so that the user discovers the wearable device.

In addition, the electronic device may further perform the steps and functions performed by the mobile phone in the above embodiments, the wearable device may further perform the steps and functions performed by the bluetooth headset in the above embodiments, and the server may further perform the steps and functions performed by the cloud server in the above embodiments, so that the method for preventing the bluetooth headset from being lost in the above embodiments is implemented.

In other scenarios, the wearable device is not lost by dropping, but is forgotten somewhere by the user to cause it to be lost, and it needs to determine that the wearable device is in the lost scenario by using the bluetooth headset loss prevention method shown in fig. 11. Or, the wearable device is not configured with an ACC sensor and cannot measure the self-acceleration, and it needs to determine that the wearable device is in a loss scene by using the bluetooth headset loss prevention method shown in fig. 11.

Fig. 11 is a schematic flowchart of another bluetooth headset loss prevention method according to an embodiment of the present disclosure. Referring to FIG. 11, the method includes S1101-S1108.

S1101, the electronic device determines that the communication quality between the electronic device and the wearable device meets a first condition.

The first condition comprises that the overtime quantity of the keep-alive messages is larger than or equal to a first threshold value, and/or the packet loss rate is larger than or equal to a second threshold value.

In some embodiments, the wearable device is forgotten somewhere, the electronic device moves away from the wearable device, and the communication quality is worse as the distance between the electronic device and the wearable device is larger. For example, the communication quality is determined by using the keep-alive messages and/or the packet loss rates of the transmission data packets transmitted between the electronic device and the wearable device, and if the number of the keep-alive messages overtime and/or the packet loss rates are larger and larger, the communication quality is worse and worse. The electronic device judges that the wearable device is in a lost scene, and needs to start a GPS to record position information.

S1102, the electronic equipment records position information and prompts the user that the wearable equipment is lost possibly in a preset reminding mode.

In some embodiments, if the electronic device is still getting worse and worse in the process of recording the position information, the position information collection frequency is increased. If the communication quality of the electronic equipment becomes good in the process of recording the position information, the position information acquisition frequency is reduced. Therefore, the position information is collected more flexibly, and the working power consumption of the GPS is reduced while the position information used for determining the auxiliary retrieval suggestion is ensured to be obtained.

S1103, the Bluetooth connection between the electronic device and the wearable device is disconnected.

S1104, the electronic equipment sends the recorded position information to the server.

S1105, the wearable device starts a low power consumption mode and broadcasts signals according to a preset period.

S1106, the server generates an auxiliary retrieval suggestion.

S1107, the server sends an auxiliary recovery suggestion to the electronic device.

S1108, the electronic equipment displays the auxiliary retrieving suggestion to assist the user in retrieving the wearable equipment.

Optionally, the remaining contents of step S1102 to step S1108 may refer to the related contents of step S1003 to step 1009, and are not described herein again.

For example, based on the method flow diagrams shown in fig. 10 and fig. 11, fig. 12 is a flow diagram of another bluetooth headset loss prevention method provided in the embodiment of the present application. Referring to fig. 12, the method includes S1201-S1210.

S1201, the wearable device determines that the acceleration is matched with the gravity acceleration.

S1202, the wearable device sends an exception notification to the electronic device.

S1203, the electronic equipment records position information and prompts a user that the wearable equipment is lost possibly in a preset reminding mode.

S1204, the electronic device determines that the communication quality between the electronic device and the wearable device meets a first condition.

S1205, the Bluetooth connection between the electronic equipment and the wearable equipment is disconnected.

In some embodiments, the electronic device monitors acceleration of the wearable device and monitors quality of communication with the wearable device after determining that the wearable device is free-falling. If the acceleration of the wearable device is kept to be zero and the communication quality is increasingly poor, the electronic device judges that the wearable device is in a lost scene, and a GPS (global positioning system) is required to be started to record the position information, namely, a wearable device retrieving mode is started.

Therefore, the electronic equipment judges whether the wearable equipment is in a lost scene or not through two judgment conditions of the acceleration and the communication quality of the wearable equipment, and the accuracy of judging the lost scene is improved.

And S1206, the electronic equipment sends the recorded position information to the server.

S1207, the wearable device starts a low power consumption mode and broadcasts signals according to a preset period.

S1208, the server generates an auxiliary retrieval suggestion.

S1209, the server sends an auxiliary recovery suggestion to the electronic equipment.

S1210, the electronic equipment displays an auxiliary retrieving suggestion to assist a user in retrieving the wearable equipment.

Optionally, the remaining contents of steps S1201 to S1210 may refer to the related contents of steps S1001 to S1009, or refer to the related contents of steps S1201 to S1208, which is not described herein again.

Optionally, the step S1201 and the step S1202 are optional steps, and if the bluetooth headset loss prevention method shown in fig. 12 does not include the step S1201 and the step S1202, the electronic device first executes the step S1204, and then executes the step S1203. That is, if the ACC sensor is not configured in the wearable device, the electronic device can directly determine whether the wearable device is in a lost scene or not and whether recording of the location information needs to be started or not based on whether the communication quality between the electronic device and the wearable device meets the first condition or not.
