Abstract

The invention discloses a method, a device and a system for prompting whether a portable positioning device arrives on time. The server determines the traveling track from one resident area to another resident area according to the recorded itinerary, and judges the current location of the portable positioning device. The location point has left a resident area, and is on the trajectory between the two resident areas, then calculate the positioning time of the last location point where the portable positioning device leaves a resident area and the portable positioning The length of time between the positioning time of the current location point of the device; judge whether the length of time exceeds the estimated travel time between the two resident areas, and if so, generate and announce that it did not arrive at another station according to the estimated travel time Reminder of the area. It can ensure that the guardian who holds the monitoring terminal knows at any time whether the ward who carries the portable positioning device arrives at the destination on time, so as to grasp the safety information of the ward and improve the user experience.
