step S100, receiving and storing the position information of the terminal of the person under guardianship; the position information includes the current position of the monitored person terminal, and is transmitted by the monitored person terminal only when the monitored person terminal and the wearable device of the monitored person are in a connected state.
Specifically, the guardian terminal and the person under guardianship terminal refer to wireless communication devices such as a smart phone and a smart watch/bracelet which are convenient for users to carry about. For example, a child and other people under guardianship, a common terminal is a smart watch, and a common wearable device is a wireless earphone which is used in cooperation with the smart watch and adopts a short-distance communication protocol (such as bluetooth, Zigbee and the like); the guardian is a corresponding parent, and most of guardian terminals are smart phones.
The guardian terminal and the monitored person terminal have a binding relationship. Those skilled in the art can understand that having the binding relationship means that the guardian terminal is a terminal having a right to receive the position information of the terminal of the person under guardianship.
The person under guardianship terminal has a gps (global Positioning system) function and can acquire the position of the person under guardianship. The location of the person under guardianship terminal may be its GPS location.
The terminal of the person under guardianship and the wearable device of the person under guardianship follow a short-distance communication protocol, so that the terminal of the person under guardianship and the wearable device of the person under guardianship can be successfully connected only within an effective distance range; when the distance between the two exceeds the effective distance, the two are generally disconnected.

When the terminal of the person under guardianship is in a connected state with the wearable device of the person under guardianship, the position of the terminal of the person under guardianship can be considered to be consistent with the position of the wearable device of the person under guardianship.
The position information of the person under guardianship terminal is only sent by the person under guardianship terminal when the person under guardianship terminal is in a connection state with the wearable device of the person under guardianship. In order to further reduce the communication flow with the guardian terminal, the guardian terminal can send out the position information of the guardian terminal at regular time, and the regular time interval can be set according to experience.
The guardian terminal receives and stores the position information of the monitored person terminal in real time. By acquiring the position information of the continuous monitored person terminal, the method is equivalent to acquiring the moving track of the wearable device of the monitored person.
Step S210, when the wearable device of the person under guardianship is found to be lost, obtaining the latest position information according to the stored position information of the terminal of the person under guardianship;
step S220 determines a lost area of the wearable device according to the latest location information.
Specifically, when a person under guardianship discovers that the wearable device of the person under guardianship is lost, or a guardian discovers that the wearable device of the person under guardianship is lost, the latest position information is acquired from the stored position information of the terminal of the person under guardianship; and determining a lost area of the wearable device according to the latest position information.

When the terminal of the person under guardianship is in a connected state with the wearable device of the person under guardianship, the position of the terminal of the person under guardianship can be considered to be consistent with the position of the wearable device of the person under guardianship.
The position information of the person under guardianship terminal is only sent by the person under guardianship terminal when the person under guardianship terminal is in a connection state with the wearable device of the person under guardianship. In order to further reduce the communication flow with the guardian terminal, the monitored person terminal can monitor the connection signal strength between the monitored person terminal and the wearable equipment of the monitored person, and send out the position information of the monitored person terminal when the connection signal strength is lower than the average signal strength by a certain threshold value.
The guardian terminal receives the position information of the monitored person terminal in real time, and circularly stores the position information of the monitored person terminal by adopting a buffer area with a fixed size. The cyclic storage means that old data is covered by new data, so that the size of a cache region can be controlled, the storage requirement on a guardian terminal is reduced, and the cost is reduced.
