When the first wearable device detects that the prompt message is not received, the distance between the current position of the wearable device and the first terminal device is beyond the coverage range of the wireless connection, and the step 206 to the step 207 are triggered to be executed; and if the fact that the prompt message is received is detected, the wearable device is shown to be disconnected from the first wireless connection with the first terminal device and establish a second wireless connection with the second terminal device, and the process is ended.

206. The first terminal equipment sends out a first alarm prompt.

In the embodiment of the invention, the first terminal device can set the safe distance value according to the requirement, and the set safe distance value is less than or equal to the maximum wireless coverage distance value of the wearable device.

For example, the first terminal device establishes a wireless connection through bluetooth, and the maximum wireless coverage distance value is 10 meters, but for the first terminal device user, the distance value of 10 meters is too large to meet the requirement, then the first terminal device user may freely set a preset safe distance value, which is less than or equal to 10 meters, for example, the first terminal device user may set the preset safe distance value to 5 meters, and execute step 310 is triggered as long as the distance exceeds 5 meters.

310. The first terminal device judges whether the moving direction of the wearable device is a direction away from the first terminal device, if so, step 311 is executed, and if not, the process is ended.

For example, when the user of the wearable device is a child, the child frequently runs back and forth, and at this time, although the distance value that runs out exceeds the preset safe distance value, the child immediately runs in the direction of the user of the first terminal device, which is not the case that the child is lost, but an alarm may be caused.
