[0037] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0038] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0039] One embodiment of the present invention, as Figure 1 As shown, a wearable device search method includes:

[0040] Step S100 receives and saves the location information of the ward's terminal; the location information includes the current location of the ward's terminal and is sent by the ward's terminal only when the ward's terminal is connected to the ward's wearable device.

[0041] Specifically, the guardian terminal and the ward terminal refer to wireless communication devices such as smart phones, smart watches / bracelets that are easy for users to carry. For example, for wards such as children, the commonly used terminals are mostly smart watches, and the commonly used wearable devices are mostly wireless headphones that use short-range communication protocols (such as Bluetooth, Zigbee, etc.) in conjunction with smart watches; the guardian is the corresponding parent, and the guardian terminal is mostly a smart phone.

[0042] The guardian terminal and the ward terminal have a binding relationship. Those skilled in the art can understand that the meaning of having a binding relationship is that the guardian terminal is a terminal that has the authority to receive the location information of the ward terminal.

[0043] The terminal of the guardian has a GPS (Global Positioning System) function and can obtain its own position. The position of the terminal of the guardian can be its GPS position.

[0044] Since the guardian's terminal and the guardian's wearable device follow a short-range communication protocol, the two can only be successfully connected within an effective distance range; when the distance between the two exceeds the effective distance, the two will generally be disconnected.

[0045] When the guardian's terminal and the guardian's wearable device are in a connected state (ie, the two are successfully connected), it can be considered that the position of the guardian's terminal is consistent with the position of the guardian's wearable device.

[0046] When the guardian's terminal is connected to the guardian's wearable device, the guardian's terminal sends its location information; when the two are disconnected, the guardian's terminal does not need to send its location information, which can save the power of the guardian's terminal.

[0047] In order to further reduce the communication traffic with the guardian terminal, when the guardian's wearable device is connected, the guardian's terminal can send its location information at regular intervals, and the timing interval can be set based on experience.

[0048] The guardian terminal receives and saves the location information of the guardian terminal in real time. By obtaining the continuous location information of the guardian terminal, it is equivalent to obtaining the movement trajectory of the guardian's wearable device.

[0049] Step S200: When the wearable device of the guardian is found to be lost, the lost area of ​​the wearable device is determined according to the saved location information of the guardian's terminal.

[0050] Specifically, when the ward finds that his / her wearable device is lost, or when the guardian finds that the ward's wearable device is lost, the lost area of ​​the wearable device is determined according to the location information of the ward's terminal stored in the guardian's terminal.

[0051] Optionally, the most recent location information is obtained based on the saved location information of the terminal of the guardian; and the lost area of ​​the wearable device is determined based on the most recent location information.

[0052] Taking a wearable device such as a Bluetooth headset as an example, the location information of the ward's terminal stored by the guardian terminal may be a record of multiple independent connection processes.

[0053] For example, a child goes to school in the morning, listens to music on the bus with headphones, stops listening to music at school, puts the headphones in his schoolbag, and listens to music on the way home from school in the afternoon. When he gets home, he stops listening to music and throws the headphones away. When he needs to use the headphones later, he finds that they are missing. Correspondingly, the guardian terminal has two pieces of location information records, corresponding to the use of the headphones in the morning time period and the use of the headphones in the afternoon time period.

[0054] When the headset is found to be lost, the last recorded location information is obtained from the saved location information of the guardian's terminal, which is also the last recorded location information. The last location information is at home, so it can be determined that the lost area of ​​the headset is at home, so the headset is searched at home.

[0055] In this embodiment, based on the connection between the wearable device of the guardian and the terminal of the guardian and between the terminal of the guardian and the guardian terminal, the location information of the wearable device of the guardian is indirectly tracked by tracking the location information of the terminal of the guardian on the guardian terminal. When the wearable device of the guardian is lost, the lost area of ​​the wearable device of the guardian can be quickly located with the help of the guardian terminal, which helps to quickly recover the lost wearable device.

[0056] Another embodiment of the present invention, as Figure 2 As shown, a wearable device search method includes:

[0057] Step S100 receives and saves the location information of the ward's terminal; the location information includes the current location of the ward's terminal and is sent by the ward's terminal only when the ward's terminal is connected to the ward's wearable device.

[0058] Specifically, the terminal of the guardian has a GPS function and can obtain its own location. The location of the terminal of the guardian refers to its GPS location.

[0059] Since the guardian's terminal and the guardian's wearable device follow a short-range communication protocol, the two can only be successfully connected within an effective distance range; when the distance between the two exceeds the effective distance, the two will generally be disconnected.

[0060] When the guardian's terminal is in a connected state with the guardian's wearable device, it can be considered that the location of the guardian's terminal is consistent with the location of the guardian's wearable device.

[0061] The location information of the guardian's terminal is sent by the guardian's terminal only when the guardian's terminal is connected to the guardian's wearable device. In order to further reduce the communication traffic with the guardian's terminal, the guardian's terminal can send its location information at regular intervals, and the regular interval can be set based on experience.

[0062] The guardian terminal receives and saves the location information of the guardian terminal in real time. By obtaining the continuous location information of the guardian terminal, it is equivalent to obtaining the movement trajectory of the guardian's wearable device.

[0063] Step S210: when the wearable device of the guardian is found to be lost, the most recent location information is obtained according to the saved location information of the guardian's terminal;

[0064] Step S220 determines the lost area of ​​the wearable device according to the most recent location information.

[0065] Specifically, when the ward finds that his / her wearable device is lost, or when the guardian finds that the ward's wearable device is lost, the most recent location information is obtained from the saved location information of the ward's terminal; and the lost area of ​​the wearable device is determined based on the most recent location information.

[0066] In this embodiment, the location information of the guardian's terminal is tracked and recorded on the guardian terminal to indirectly track and record the location information of the guardian's wearable device. When the guardian's wearable device is lost, the guardian terminal can be used to quickly locate the lost area of ​​the guardian's wearable device, which helps to quickly recover the lost wearable device.

[0067] Another embodiment of the present invention, as Figure 3 As shown, a wearable device search method includes:

[0068] Step S110 receives the location information of the terminal of the ward; the location information includes the current location of the terminal of the ward, and is sent by the terminal of the ward only when the terminal of the ward is connected to the wearable device of the ward.

[0069] Step S120 uses a fixed-size buffer area to cyclically save the location information of the terminal of the guardian.

[0070] Specifically, the terminal of the guardian has a GPS function and can obtain its own location. The location of the terminal of the guardian refers to its GPS location.

[0071] Since the guardian's terminal and the guardian's wearable device follow a short-range communication protocol, the two can only be successfully connected within an effective distance range; when the distance between the two exceeds the effective distance, the two will generally be disconnected.

[0072] When the guardian's terminal is in a connected state with the guardian's wearable device, it can be considered that the location of the guardian's terminal is consistent with the location of the guardian's wearable device.

[0073] The location information of the guardian's terminal is sent by the guardian's terminal only when the guardian's terminal is connected to the guardian's wearable device. In order to further reduce the communication traffic with the guardian's terminal, the guardian's terminal can monitor the connection signal strength between the guardian's terminal and the guardian's wearable device, and send its location information when the connection signal strength is lower than a certain threshold of the average signal strength.

[0074] The guardian terminal receives the location information of the guardian terminal in real time, and uses a fixed-size buffer area to cyclically save the location information of the guardian terminal. Cyclic saving means overwriting old data with new data, which can control the size of the buffer area, reduce the storage requirements of the guardian terminal, and reduce costs.

[0075] Step S210: when the wearable device of the guardian is found to be lost, the most recent location information is obtained according to the saved location information of the guardian's terminal;

[0076] Step S221 determines the lost area of ​​the wearable device according to the most recent location information and location information received within a preset range before the most recent location information.

[0077] Specifically, when the ward finds that his / her wearable device is lost, or the guardian finds that the ward's wearable device is lost, the most recent location information is obtained from the saved location information of the ward's terminal; the lost area of ​​the wearable device is determined based on the most recent location information and the previous several location information (the previous number can be set based on experience). By expanding the search range, the success rate of finding wearable devices can be increased.

[0078] In this embodiment, by adopting the method of cyclically saving the location information of the terminal under guardianship, it is helpful to reduce the storage requirements for the guardian terminal and reduce the cost; and the success rate of finding the wearable device is improved by expanding the search range.

[0079] One embodiment of the present invention, as Figure 4 As shown, a wearable device search device includes:

[0080] The receiving module 100 is used to receive the location information of the terminal of the guardian; the location information includes the current location of the terminal of the guardian, and is sent by the terminal of the guardian only when the terminal of the guardian is in a connected state with the wearable device of the guardian.

[0081] The storage module 200 is used to store the location information of the terminal of the guardian.

[0088] In order to further reduce the communication traffic with the guardian terminal, when the guardian's wearable device is connected, the guardian's terminal can send its location information at regular intervals, and the timing interval can be set based on experience.

[0089] The guardian terminal receives and saves the location information of the guardian terminal in real time. By obtaining the continuous location information of the guardian terminal, it is equivalent to obtaining the movement trajectory of the guardian's wearable device.

[0090] The positioning module 300 is used to determine the lost area of ​​the wearable device according to the saved location information of the terminal of the guardian when the wearable device of the guardian is found to be lost.

[0091] Specifically, when the ward finds that his / her wearable device is lost, or when the guardian finds that the ward's wearable device is lost, the lost area of ​​the wearable device is determined according to the location information of the ward's terminal stored in the guardian's terminal.
