For ease of understanding, in the following embodiments, the first terminal device is a child's watch, the second terminal device is a parent's mobile phone, and the management application is a "smart care" application to illustrate the terminal device control method provided by the embodiments of the present application.

The following is a brief introduction to the terminal equipment control method provided by this application.

In the embodiment of the present application, the children's watch can obtain the location indication information used to indicate the area where the child's watch is located, and control the working status of the mobile communication module and/or positioning module of the child's watch based on the location indication information. If the location indication information indicates that the terminal device is located in the preset area, the mobile communication module and/or the positioning module are turned off. In this way, the power consumption of the children's watch can be reduced and the standby time of the children's watch can be extended. The preset area may be a user-specified area, and the preset area may include one or more fixed areas, that is, areas that can be determined in advance, such as the area occupied by the school (school area) or the location of the home. It is an area with a center radius of 50 meters (home area); or, an area on the path between two fixed areas, such as the area occupied by school buses on the path from the home area to the school area; or, A variable area, such as a location 30 meters around a moving phone.

The following describes the terminal device control method provided by the embodiment of the present application when the first terminal device is a children's watch with reference to specific scenarios.

As shown in (a) of Figure 7, the "Smart Care" application on the mobile phone may include a "Work Mode" option 701. As shown in (b) of Figure 7, the mobile phone can receive the parent's operation on the "working mode" option 701, such as the first operation. The first operation may be any operation such as a click operation, a long press operation, or a double-click operation by the parent on the "working mode" option 701. In response to the first operation, as shown in Figure 8, the mobile phone may display a "Mode Settings" tab 801, and the "Mode Settings" tab 801 may include multiple options. For example, the "Mode Settings" tab 801 may include a "School Mode" option 811, a "Company Mode" option 812, and may also include a "Parameter Settings" option 813. Among them, the "school mode" option 811 is used to select the children's watch to work in the "school mode". For details, please refer to the method embodiment shown in Figure 10 below. The "Companion Mode" option 812 can be used to select the child's watch to work in the "Companion Mode". For details, please refer to the method embodiment shown in Figure 17 below. The "parameter setting" option 813 can be used to set parameters related to the working mode of the children's watch in the "school mode" or "accompanying mode". For details, please refer to the method embodiment shown in Figure 10 and the method implementation shown in Figure 17 below. For example, we will not go into details here.

The following further explains the process of children's watches entering "school mode".

For example, before children go to school, parents can operate the "school mode" option 811 in the tab shown in (a) in Figure 9, and the mobile phone can receive the parents' operations on the "school mode" option 811, Like the second operation. The second operation may be a parent's click operation, long press operation or double click operation on the "school mode" option 811, etc. Any kind of operation. In response to the second operation, the mobile phone displays the interface shown in (b) of Figure 9 , in which the "school mode" option 811 becomes selected. In addition, in response to the second operation, the mobile phone can send the first message to the first network device (the first network device can provide services for children's watches and terminal devices, such as location query of children's watches, settings of children's watches, etc.), wherein, The first message is used to indicate that the working mode of the selected children's watch is "school mode". After receiving the first message, the server sends a second message to the child's watch according to the first message, where the second message is used to instruct the child's watch to turn on the "school mode" (ie, the first working mode). After the children's watch receives the second message, it can turn on the "school mode".

In addition, similar to setting the "school mode" on the parent's mobile phone in Figure 9, you can also set the "school mode" on the child's watch, which will not be described again here.

After the "school mode" is turned on, the children's watch can perform the following steps S1001 to S1002. The following is an example of how a child's watch turns on the "school mode" and the child takes a school bus to school.

S1001, the children's watch obtains location indication information.

Among them, the location indication information is used to indicate whether the children's watch is located in the school bus area, that is, within the preset area.

The preset area indicated by the location indication information of the child's watch may be related to the working mode enabled by the child's watch, such as "school mode". In this way, the terminal device can detect the corresponding location indication information according to the working mode. For example, when only one type of device exists in the preset area, signal detection can be performed for that type of device to obtain the location indication information, thereby simplifying the information. acquisition process to further extend the standby time.

For example, the location indication information can be obtained based on the following manner.

Method one is to obtain location indication information based on WLAN, such as wireless fidelity (WIFI) technology.

Taking WIFI technology as an example, in this case, the school bus is equipped with a WIFI signal sending device (hereinafter referred to as WIFI device), and the children's watch working in "school mode" turns on the WIFI signal detection function. At this time, the location indication information may include identification information of the WIFI device from which the child's watch detects the WIFI signal, or the location indication information may also include the signal strength of the WIFI signal received by the child's watch. The children's watch can obtain the identification information of the WIFI device that has detected the WIFI signal and the signal strength of the WIFI signal, thereby obtaining location indication information. Among them, the children's watch pre-stores the identification information of the WIFI device in the school bus. If the child's watch detects the signal sent by the WIFI device installed in the school bus, it is determined that the child's watch is in the school bus area, that is, the preset area. If the child's watch does not detect the signal sent by the WIFI device installed in the school bus, it is determined that the child's watch is in the school bus area, that is, outside the preset area. For example, when the child's watch detects a signal sent by a WIFI device installed in the school bus, it may be that the child's watch detects that the signal strength of the signal sent by the WIFI device installed in the school bus is greater than or equal to the first signal strength threshold. If the child's watch does not detect the signal sent by the WIFI device installed in the school bus, it may be that the child's watch detects that the signal strength of the signal sent by the WIFI device installed in the school bus is less than the first signal strength threshold.

For example, the first signal strength threshold may be -90 decibel relative to one milliwatt (dBm). Here, the first signal strength threshold is only used as an example. In specific implementation, the first signal strength threshold can be determined according to the actual situation, such as the transmission power of the WIFI device and/or the range of the school bus (preset area), etc. No further details will be given here.

Method 2: Obtain location indication information based on Bluetooth.

In this case, the school bus is equipped with a Bluetooth signal sending device (hereinafter referred to as the Bluetooth device). The children's watch working in "Mode" turns on the Bluetooth signal detection function. At this time, the location indication information can include the identification information of the Bluetooth device corresponding to the Bluetooth signal detected by the child's watch. The location indication information can also include the Bluetooth signal received by the child's watch. Strength. The children's watch can obtain the identification information of the Bluetooth device that detects the Bluetooth signal and the signal strength of the Bluetooth signal, thereby obtaining the location indication information. Among them, the children's watch pre-stores the identification information of the WIFI device in the school bus. If the children's watch detects If the child's watch does not detect the signal sent by the Bluetooth device set up in the school bus, it is determined that the child's watch is in the school bus area, that is, within the preset area. If the child's watch does not detect the signal sent by the Bluetooth device set up in the school bus, it is determined that the child's watch is in the school bus area, that is, Outside the preset area. For example, if the child's watch detects a signal sent by a Bluetooth device installed in the school bus, it may be that the child's watch detects that the signal strength of the signal sent by the Bluetooth device installed in the school bus is greater than or equal to the second signal strength. Threshold. The child's watch does not detect the signal sent by the Bluetooth device installed in the school bus. This may be because the child's watch detects that the signal strength of the signal sent by the Bluetooth device installed in the school bus is less than the second signal strength threshold.

For example, the second signal strength threshold may be -90dBm. The specific value of the second signal strength threshold may be determined based on the transmission power of the Bluetooth device and/or the range of the school bus (preset area). It can be understood that the second signal strength threshold is only used as an example. In specific implementation, the second signal strength threshold can be based on actual conditions, such as the transmission power of the Bluetooth device and/or the range of the school bus (preset area), etc. OK, no more details here.

In a possible design, the children's watch can establish a Bluetooth connection with the mobile phone. If the Bluetooth connection between the children's watch and the Bluetooth device exists, the children's watch is located in the school bus area. If the Bluetooth connection between the children's watch and the Bluetooth device exists, If the connection is lost, the child's watch is in an area outside the school bus area.

Among them, Bluetooth devices and smart watches can use Bluetooth low energy (BLE) technology to send or receive signals.

Method 3: Obtain location indication information based on near field communication (NFC) technology.

In this case, the school bus is equipped with an NFC device, and the children's watch working in "school mode" turns on the NFC detection function. The location indication information is the identification information indicating whether the children's watch can read the NFC device in the school bus through NFC technology. When children get on the bus, they can put the children's watch close to the NFC device to obtain the identification information of the NFC device. If the child's watch detects the NFC device installed in the school bus, it is determined that the child's watch has entered the school bus, that is, within the preset area.

It can be understood that in the embodiment of the present application, the above methods for obtaining position indication information are only used as examples. The children's watch can also obtain position indication information through other existing methods, which will not be described again here. In addition, in the embodiment of the present application, the location indication information can also be determined by combining existing methods to obtain the location indication information, such as the above-mentioned methods one to three.

It should be noted that the WIFI devices, Bluetooth devices, and NFC devices in the school bus can all be called first default devices. The first default devices can also include other devices, which will not be described again here. The type of device (device type) in the preset area that can be used to assist the children's watch in determining the location is the preset type. That is to say, the preset type of device can include a device for sending Bluetooth signals, a device for sending WIFI signals, Device, or near field communication NFC device, that is, WIFI device, Bluetooth device, NFC device. The detection result of the preset type of device may include the device identification of the first preset device. The detection result of the preset type of device may also include the signal strength of the signal sent by the first preset device.

S1002, if the location indication information indicates that the child's watch is located in the school bus, turn off the mobile communication module and/or bit module.

Regarding the implementation method of turning off the mobile communication module, you may refer to the specific implementation method of turning off the mobile communication module in the prior art; regarding the implementation method of turning off the mobile communication positioning module, you may refer to the specific implementation method of turning off the mobile communication module in the prior art. No further details will be given.

In this way, if the location indication information indicates that the child's watch is in the school bus and the child is in a relatively safe area, the child does not need to use the mobile communication function. In this way, the mobile communication module can be turned off and the parents do not need to obtain the child's real-time information from the "Smart Care" application. In this way, the positioning module can be turned off, that is, the mobile communication module and/or the positioning module can be turned off, thereby reducing the power consumption of the communication module and/or the positioning module to extend the standby time of the children's watch.

If a child leaves the school bus, if the child takes the school bus to the outside of the school, gets off the bus and walks into the school, the closed modules in the mobile communication module and positioning module will be reopened.

For example, if method 1 is used to obtain location information, when the child's watch detects that the signal strength of the signal sent by the WIFI device installed in the school bus is less than the first signal strength threshold, the child leaves the school bus. If the second method is used to obtain location information, the child's watch detects that the signal strength of the signal sent by the Bluetooth device installed in the school bus is less than the second signal strength threshold, or the Bluetooth connection between the child's watch and the Bluetooth device in the school bus is disconnected. state when children leave the school bus. If method three is used to obtain location information, the child leaves the school bus when the child's watch reads the signal sent by the NFC device in the school bus again.

In another possible scenario, after the children's watch is set to "school mode", when the children enter the school from outside the school, for example, after the children get off the car outside the school and walk into the school, the default area is the school area. , in this case, the control method of the children's watch can refer to the method embodiment shown in Figure 10 above. In this case, if the child does not enter the school area, the location indication information can also be determined based on the location of the child's watch detected by the positioning module.

In addition, if the children's watch is working in "school mode", the children's watch can also activate the sensors in the sensor module, such as motion sensors or ambient light sensors, to detect the relevant status of the children's watch. Among them, the motion sensor includes an acceleration sensor.

Taking the motion sensor as an example, if the children's watch is working in "school mode", the children's watch can activate the motion sensor to detect the child's motion status. At this time, in a possible design, the children's watch can also perform the following steps 1 to 4.

Step 1: The children's watch obtains the acceleration of the children's watch through the acceleration sensor, and determines the movement speed (i.e., motion state) of the children's watch based on the acceleration of the children's watch.

Among them, the moving speed of the child's watch can indicate the possibility of the child moving outside the school area. If the child's moving speed is greater than or equal to the speed threshold, the child is likely to move outside the school area. In this case, the children's watch can perform the following step 2.

Among them, the speed threshold can be determined according to the actual situation. For example, the speed threshold may be determined according to the speed of the vehicle, for example, the speed threshold may be 20 kilometers per hour to 30 kilometers per hour. It can be understood that the speed threshold here is only used as an example and does not specifically limit the speed threshold. During specific implementation, the speed threshold can be determined according to the actual situation, such as the size of the school area, and will not be described again here.

Step 2: Turn on the positioning module of the children's watch.

Step 3: If the child’s watch determines that the child’s watch has not left the school area through the position detected by the positioning module, Then close the positioning module again.

Step 4: If the mobile communication module is turned off and the child's watch determines that the child has left school based on the location detected by the positioning module, the mobile communication module is further turned on.

In this way, it can be determined whether a child is riding in a car, and if the child moves too fast, such as leaving the school area by car after school, the positioning module can be turned on in time to detect the child's position, thereby further improving the safety of the child.

In other possible designs, the children's watch can also determine the movement distance of the children's watch relative to the reference position (ie, the motion state) based on the acceleration obtained by the acceleration sensor. If the movement distance of the child's watch relative to the reference position is greater than or equal to the distance threshold, the child is likely to move outside the school area. In this case, the child's watch can still perform the above steps 2 to 4, which are not discussed here. Repeat. The reference position is the starting point used to determine the distance the child moves. For example, if the positioning module has not been turned on after the child's watch leaves the teaching area, the reference position can be the position of the teaching area; or, if the positioning module has been turned on after the child's watch leaves the teaching area, the reference position can be the last time the child's watch was turned on. The position detected by the positioning module. By way of example, the distance threshold may be 100 meters. It can be understood that the distance threshold here is only used as an example and does not specifically limit the distance threshold. During specific implementation, the distance threshold can be determined based on the actual situation, such as the size of the school area, and will not be described again here.

It should be noted that the above-mentioned motion sensor may be a three-axis IMU, a six-axis IMU, or a nine-axis IMU, which is not specifically limited in this application.

In this way, the motion sensor can detect the movement status of the children's watch in more directions, such as acceleration, so as to obtain more accurate displacement and further improve safety.

Or, taking the ambient light sensor as an example, when a child enters school, the child's watch can activate the ambient light sensor to detect whether the child has left the building area (motion state) such as the classroom in the school area, and then determine whether the child is likely to leave the school. .

For example, if the light intensity detected by the ambient light sensor of the child's watch is greater than or equal to the light intensity threshold, the child is outside the building area of the school area. In this case, the positioning module and mobile communication module of the child's watch can be turned on. The light intensity may be the intensity of visible light or the intensity of invisible light. For example, for visible light, the light intensity threshold may be: Light intensity threshold: 2000 lux. For invisible light, such as ultraviolet light, the light intensity can be 1100 megawatt per square meter (mW/m ² ). It can be understood that the light intensity threshold here is only used as an example and does not specifically limit the light intensity threshold. During specific implementation, the light intensity threshold can be determined based on actual conditions, such as weather, etc., which will not be described again here.

In this way, children's location information can be updated in a timely manner, further improving safety.

It is understandable that if the processor of the children's watch is a multi-core processor and includes an AP and an MCU, in this case, as shown in Figure 5 above, some sensors in the sensor module can be connected to the MCU. In the sensor module, the signals collected by the motion sensor and light sensor can be transmitted to the MCU and processed by the MCU to obtain the motion status of the children's watch, thereby realizing motion status monitoring.

In addition, children's watches can also collect environmental sounds through microphones, and then monitor children's movement status based on environmental sounds. For example, if a child leaves the school by car or bicycle after school, the children's watch can collect sound signals in the surrounding environment through the microphone, and detect vehicle movement in the detected sound signals. In the case of sound signals generated while driving, the positioning module and/or mobile communication module are turned on.

It should be noted that in the embodiment of the present application, the children's watch can determine the movement state of the children's watch based on one of the movement speed of the children's watch, the movement distance of the children's watch, or the light intensity detected by the children's watch, or it can also be combined with the movement status of the children's watch. The location of the child's watch is determined by a combination of movement speed, distance traveled by the child's watch, or light intensity detected by the child's watch.

Step 5: The children's watch obtains the data collected by each sensor through the MCU, and obtains the movement status of the children's watch based on the data collected by each sensor.

In another possible embodiment, the child enters the home area from an area outside the home area. At this time, the control method of the children's watch is similar to that when the child enters school, and will not be described again here.

In some scenarios, parents can update the preset area according to the actual situation. For example, parents apply for out-of-school care services for their children. In this case, the parents can set the area where the care institution is located as the default area. Children's watches can still work in "school mode" after entering the area where the child care institution is located. The working principle of children's watches in day care institutions is similar to the working principle of children's watches in school areas, so we will not go into details here.

The process of updating the preset area is as follows: the parent's mobile phone can receive the parent's third operation of the "parameter setting" option 813 in (a) in Figure 11 . The third operation may be any operation such as a click operation, a long press operation, or a double-click operation by the parent on the "parameter setting" option 813. In response to the third operation, the mobile phone can display the "Parameter Item" tab 1101 as shown in (b) of Figure 11. The "Parameter Item" tab 1101 includes options for the area that have been set, such as "Area 1" option, the "Zone 2" option, and the "Add New Zone" option 1111. The "Parameter Items" tab 1101 may also include already set distance options, such as the "Distance 1" option, the "Distance 2" option, and the "Set Companion Distance" option 1112. Among them, as shown in (a) of Figure 12, the mobile phone can receive the parent's fourth operation on the "add new area" option 1111. The fourth operation may be any operation such as a click operation, a long press operation, or a double-click operation by the parent on the "Add New Area" option 1111. In some possible designs, in response to the fourth operation, the mobile phone can display the "Area 3" option as shown in (b) of Figure 12 . The fourth operation may be an operation of inputting information that requires a newly added preset area.

For example, the information of the preset area input by the fourth operation may be, for example, the identification information of the WIFI device in the preset area.

For another example, the information of the preset area of the fourth operation input may be the input of a specific location. In this case, the mobile phone may respond to the fourth operation and set the area where the position of the fourth operation input is located as the preset area. For example, the location input in the fourth operation is a location in the area where the managed school is located. In this case, the mobile phone can set the area where the managed school is located as a default area.

In some possible designs, in response to the fourth operation, the mobile phone can display the "designated area" interface as shown in Figure 13. In this case, the mobile phone can receive the fifth operation of the parent on the "designated area" interface. The fifth operation may be any operation such as a click operation, a long press operation or a double-click operation by the parent on the "specified area" interface. In response to the fifth operation, the area corresponding to the position is set as the preset area. Among them, the mobile phone can store the corresponding relationship between the location and the area. For example, the area corresponding to each location in the trusteeship school is the area where the trusteeship school is located. Location 1 is located in the area where the trusteeship school is located. Then the mobile phone can respond to the parent's request for location 1. The fifth operation is to add the area where the managed school is located as a default area.

In some possible designs, in response to the fourth operation, the mobile phone can display a "specified area" interface as shown in Figure 14. The "specified area" interface includes graphics of different areas (such as a map). The mobile phone can receive parents For the sixth operation of the "specify area" interface, in response to the sixth operation, the area formed by the sixth operation is determined as the preset area. The sixth operation may be for the parent to manually specify an area. For example, the parent manually slides around the periphery of the custody school (the sliding trajectory is shown as a dotted line in Figure 14). In this case, in response to the sixth operation, the mobile phone can move the custody school to The area is set as the default area.

It can be understood that in the embodiment of the present application, the mobile phone can also automatically set the path between two preset areas as the preset area according to the preset area that has been obtained, when there are multiple fixed preset areas. For example, after the home community and school are set as default areas, the mobile phone can also set the path between the home community and the school as the default area, or it can use a method similar to setting the area where the managed school is located as the default area. , set the path between Community A and the school as the default area.

In some embodiments, as shown in (a) of Figure 15, the mobile phone can receive the parent's operation on the area option, thereby deleting the corresponding area. For example, the mobile phone can receive the parent's seventh operation on the "Area 1" option. The seventh operation may be any operation such as a click operation, a long press operation, or a double-click operation by the parent on the "Area 1" option. In response to the seventh operation, the mobile phone deletes the "Area 1" option and displays the interface shown in (b) of Figure 15 .

In another possible embodiment, the children and their parents are together. For example, the parents pick up the children after school. At this time, the parents can obtain the children's location information in time. In this case, the child's watch and the parent's mobile phone can be connected. Through short-distance methods, such as Bluetooth, ZigBee, WLAN, etc. The following is an example of Bluetooth communication between a child's watch and a parent's mobile phone.

In this case, as shown in (a) of FIG. 16 , the parent can perform an eighth operation on the "accompanying mode" option 812. The eighth operation may be any operation such as a click operation, a long press operation, or a double-click operation by the parent on the "accompanying mode" option 812. The mobile phone responds to the parent's eighth operation. On the one hand, the mobile phone can send a third message to the server. Among them, the third message is used to instruct the children's watch to work in "accompanying mode". After receiving the third message, the server sends the fourth message to the child's watch. After receiving the fourth message, the children's watch can turn on Bluetooth and work in "companion mode" (that is, the second working mode). On the other hand, as shown in (b) of FIG. 16 , the "companion mode" option 812 becomes selected, and the parent's mobile phone can turn on Bluetooth.

In addition, similar to setting the companion mode on the parent's mobile phone in Figure 16, the "companion mode" can also be turned on on the child's watch, which will not be described again here.

For example, after the children's watch works in "companion mode", the children's watch can perform the following steps S1701 to S1702.

S1701, the children's watch detects Bluetooth signals and obtains location indication information.

In this case, the location indication information is: information related to the Bluetooth signal detected by the child's watch, for example, the device identification of the device that emits the Bluetooth signal (hereinafter referred to as the Bluetooth device), the signal strength of the Bluetooth signal, etc.

The preset area indicated by the position indication information of the child's watch may be related to the working mode of the child's watch, such as "accompanying mode". In this way, the terminal device can detect the corresponding location indication information according to the working mode. For example, when there is only one type of device in the preset area, the signal can be detected for that type of device to obtain the location indication information, which can simplify the information. acquisition process to further extend the standby time.

S1702, if the child's watch detects the Bluetooth signal sent by the parent's mobile phone, it turns off the mobile communication module and/or positioning module.

For example, when the child's watch detects the Bluetooth signal sent by the parent's mobile phone, it may be that the child's watch detects that the signal strength of the Bluetooth signal from the parent's mobile phone is greater than or equal to the third signal strength threshold, or it may be that the child There is a Bluetooth connection between the watch and the parent's phone. At this time, the children's watch can turn off the mobile communication module and/or positioning module.

In order to better balance the safety of children and the power consumption of children's watches, the third signal strength threshold can be set by parents or children. For example, a third signal strength threshold can be set for a child's watch via the parent's cell phone. For example, the third signal strength threshold may be -90dBm.

Illustratively, similar to (a) in Figure 11, the mobile phone may receive a third operation on the "parameter setting" option 813, and in response to the third operation, the mobile phone may display as shown in (b) in Figure 11 interface. As shown in (a) in Figure 18, the mobile phone can receive the ninth operation (input the new companion distance 3) of the "set companion distance" option 1112 shown in (b) in Figure 11 from the parent, as shown in Figure 18 The "distance 3" option in (b). The mobile phone can receive the parent's operation on the distance option (such as the "Distance 1" option to the "Distance 3" option), and respond to the parent's operation on the distance option, and select the distance corresponding to the preset area in the "Companion Mode", that is, the children's watch distance from the phone.

In this way, when children are with their parents, the children are in a relatively safe area, and the children do not need to use the mobile communication function. In this way, the mobile communication module can be turned off, and the parents do not need to obtain the children's real-time location from the "Smart Care" application. , the positioning module can be turned off, that is, the mobile communication module and/or the positioning module can be turned off, thereby reducing the power consumption of the communication module and/or the positioning module to extend the standby time.

In the embodiment of this application, the positioning of children's watches can be assisted through parents' mobile phones based on BLE or Bluetooth proxy (BT proxy). For example, the location of a child's watch can be determined based on the location of the parent's cell phone and the strength of the Bluetooth signal detected by the child's watch.

In the embodiment shown in Figure 17, in order to ensure children's communication needs, network services can be provided based on BLE or Bluetooth proxy. At this time, the children's watch is connected to the parent via Bluetooth and forwards information through the parent's mobile phone. For example, if a child needs to communicate with classmates, in this case, the child's watch can send the first communication information, and the parent's mobile phone can then send the first communication information after receiving the first communication information sent by the child's watch. After receiving the second communication information from the classmate's terminal device, the parent sends the second communication information, and the child's watch receives the second communication information from the parent's mobile phone. In this way, the communication function of the child's watch can be realized.

When the children's watch is working in "companion mode", if the child's watch detects that the signal strength of Bluetooth is less than the third signal strength threshold, the mobile communication module and the positioning module can be turned on to make the mobile communication module and the positioning module work. If the parent's mobile phone detects that the Bluetooth signal strength is less than the third signal strength threshold, it can also output a reminder message to remind the parent. Among them, the reminder information can be displayed on the interface of the mobile phone, or output through voice or vibration.

In addition, if parents and children are in a densely populated area, in order to prevent children from getting separated from their parents and better ensure the safety of children, as shown in (a) in Figure 19, parents’ mobile phones can also receive parents’ comments about “accompanying them”. Mode" tenth operation of option 812. The tenth operation may be any operation such as a click operation, a long press operation, or a double-click operation by the parent on the "accompanying mode" option 812. In response to the tenth operation, the mobile phone can end the working state of the child's watch in the "accompanying mode", turn on the positioning module and mobile communication mode, and display the interface as shown in (b) of Figure 19, in which the "accompanying mode" option 812 is unselected.

It is understandable that in "companion mode", children's watches can also use other short-distance communication methods besides Bluetooth communication, such as ZigBee, WLAN, etc., which are not limited here.

In "companion mode", a mobile phone that establishes a Bluetooth connection with the children's watch can also use the children's watch's movements to Status information and location are sent to the first network device for other parents to query.

In addition, when children are not in the preset area, such as when children are playing independently in the community, the communication module and positioning module of the children's watch can be turned on. At this time, the working mode of the children's watch can become "independent mode".

It can be understood that in the embodiment of the present application, the children's watch can be switched between school mode, companion mode and independent mode. The following is an example with reference to Figure 20.

As shown in Figure 20, the child enters the school. At this time, the child's watch determines that the child's watch has entered the school area based on the location indication information. In this case, the children's watch enters "school mode" and turns off the positioning module and/or mobile communication module. Children's watch obtains sports status information. If the child's watch determines that the child's motion status meets the first condition based on the motion status information, such as the child moving 100 meters relative to the classroom, or the child's moving speed is greater than 30 kilometers per hour, the positioning module is turned on.

In this case, if it is determined that the child is still in the school area based on the location indication information, the child's motion status information will continue to be obtained. If it is determined based on the location indication information that the child is not in the school area, and it is detected that the signal strength of the Bluetooth signal sent by the parent's mobile phone is greater than the third signal strength threshold (accompanied by the parent), it will enter the "accompanying mode" operation. If it is determined based on the location indication information that the child is not in the school area and is not in other preset areas outside the school area, the positioning module and mobile communication module are turned on, that is, the "independent mode" is entered.

It should be noted that in the embodiment of this application, after the parent operates the options in the "Smart Care" application on the mobile phone, the mobile phone can synchronize the relevant information to the child's watch. For example, in "companion mode", the mobile phone can send information about operating options through Bluetooth, and the children's watch can receive the information through Bluetooth.

It can be understood that in the embodiment of the present application, the children's watch can also determine whether to automatically enter the "school mode" or "accompanying mode" based on the indication result of the location indication information. That is to say, in this case, the child's watch can execute the method shown in FIG. 10 or the method shown in FIG. 17 without setting the working mode through the parent's mobile phone or the child's watch.

In this way, the operation steps can be simplified and the user experience can be improved.

Furthermore, the children's watch can also perform the method shown in FIG. 10 or the method shown in FIG. 17 by itself in combination with the time period. For example, the preset working time period of the children's watch in "school mode" is from 8 am to 5 pm every day from Monday to Friday. If the children's watch detects that the location of the child's watch is within the school area, and If the time is any time period between 8 am and 5 pm every day from Monday to Friday, the children's watch enters the school mode, that is, the children's watch turns off the positioning module and/or mobile communication module.

If the preset "accompanying mode" working time period in the child's watch is from 5 pm to 8 pm from Monday to Friday, if the child goes home with the child after school, the child's watch detects the message sent by the parent's mobile phone. Bluetooth signal, and the time is any time period between 5 pm and 8 pm every day from Monday to Friday, the children's watch enters the "accompanying mode", that is, the children's watch turns off the positioning module and/or mobile communication module.

In this way, mode settings can be intelligently implemented to further improve user experience.

For example, the working modes of the children's watch corresponding to the scene in which the child's watch is located, as well as the time in each scene of daily life (such as Monday to Friday) and weekends are shown in Table 1.

Table 1

For the scenario shown in Table 1, if the terminal device is controlled according to the solution of the embodiment of the present application, the terminal device can turn off the mobile communication module and positioning module most of the time in a day, thereby reducing the power consumption of the terminal device and extending the standby time. time.

In summary, based on the terminal device control methods provided in Figures 10 and 17, the terminal device can control the working status of the mobile communication module and the positioning module based on the area indicated by the location indication information. When the location indication information indicates that the children's watch is located in the preset area For example, when children are in relatively safe areas such as schools and families, the mobile communication module and positioning module are turned off, thereby reducing the power consumption of the communication module and positioning module and taking into account the safety of the wearer and the standby time of the terminal device.
