Position information prompting method, device and system

Abstract

The present invention discloses a position information prompting method, device, and system. A designated server receives from a portable locator multiple position point information obtained according to pre-set time and positioning time corresponding to each position point information, generates a movement track of the portable locator, and records the movement track; then, when the designated server receives the current position point information transmitted by the portable locator, according to the current position point information, an alert signal is generated if the current position point corresponding to the current position point information is not on the recorded movement track. A guardian holding a monitoring terminal can be ensured to know at any time whether the person being monitored and holding the portable locator is on a strange road, and thereby the safety information of the monitored person is mastered, and the user experience is enhanced.
