S2: and calculating the distance between the real-time position of the computer and the real-time position of the user terminal, and forming a distance difference value.

Specifically, the distance difference is equal to the subtraction of the real-time position of the computer and the real-time position of the user terminal. For example, when the real-time location of the computer minus the real-time location of the user terminal is equal to 500 meters, the distance difference is 500 meters.

S3: and judging whether the distance difference value is larger than a preset safe distance value.

If yes, the process proceeds to S4.

If no, the process goes to S7.

Specifically, after the distance difference is calculated, the distance difference is compared with a preset safety distance entry, and whether the distance difference is greater than a preset safety distance is judged. Wherein the preset safety distance is entered in advance by the user. For example, the preset safe distance is set to 2 meters, and when the distance difference is 10, the process goes to S4.

S4: and forming distance alarm information.

Wherein, the distance alarm information is the information when the distance difference is greater than the preset safe distance.

S5: forming a control instruction.

Specifically, the control instruction is used for controlling an alarm to give an alarm, the alarm is installed on a user terminal and belongs to a carrier on the user terminal, the alarm is actually a buzzer, and the control instruction controls the buzzer to give an alarm sound so as to remind a user of checking whether a computer is lost.

Referring to fig. 2, after S5, the method further includes:

s6: responding to the decision information.

Specifically, the determination information is entered after being checked by the user. The specific content of the judgment information includes "theft is confirmed" and "alarm is cancelled". For example, after the alarm gives an alarm, the computer is automatically checked whether the computer is stolen, and the check result is input, namely, the judgment information is input.

S7: the content of the judgment information is judged.

If a decision is made that "theft is determined", the flow proceeds to S8.

If it is judged to be "cancel alarm", the flow goes to S14.

Specifically, after the alarm gives an alarm sound, the user checks the computer by himself to judge whether the computer is lent to others for use, forgotten to carry, stolen, or the like.

S8: forming a query distance instruction.
