and if the first distance is smaller than or equal to the second preset distance, sending the current positioning information of the first terminal to the second terminal at regular time according to a third preset time interval, wherein the second preset time interval is smaller than the third preset time interval.
6. The loss prevention reminding method according to claim 1, wherein before the step of obtaining the positioning information of the first terminal if the motion of the first terminal is detected, the method further comprises:
acquiring historical position information of the first terminal within a preset time length;
acquiring the repeated occurrence frequency of each historical position information;
and acquiring the preset position range according to the historical position information and the frequency.
7. The loss prevention reminding method according to claim 6, wherein the step of obtaining the preset position range according to the historical position information and the frequency comprises:
acquiring first position information and second position information, wherein the first position information is the historical position information with the maximum repeated frequency, and the second position information is the historical position information except the first position information in the historical position information;
acquiring a second distance between each piece of second position information and the first position information;
acquiring the repeated occurrence frequency of the second position information of which the second distance is greater than a third preset distance;
if the frequency of the second position information with the second distance larger than a third preset distance is in a reference frequency interval, acquiring the preset position range by taking the first position information and the second position information with the first distance larger than the third preset distance as circle centers;
the reference frequency interval is obtained according to the frequency of the first position information and the frequency of the second position information of which the second distance is greater than a third preset distance.
8. A first terminal, characterized in that the first terminal comprises: acceleration sensor, location module, memory, processor and anti-loss reminder stored on the memory and executable on the processor, which when executed by the processor implements the steps of the anti-loss reminder method according to any of claims 1 to 7.
9. A loss prevention reminder system, comprising: a first terminal and a second terminal as claimed in claim 8, the first terminal being paired with and communicatively coupled to the second terminal.
10. A readable storage medium, having a loss prevention reminding program stored thereon, which when executed by a processor implements the steps of the loss prevention reminding method according to any one of claims 1 to 7.
