Method, device and system for prompting whether portable positioning device arrives on time or not

Abstract

The invention discloses a method, device and system for prompting whether a portable positioning device arrives on time or not. A server determines an advancing track between one parking area to another parking area according to a recorded route, calculates time duration between positioning time when the portable positioning device leaves the final position point in the one parking area and positioning time of a current position point of the portable positioning device when judging that a current position point of the portable positioning device is not within the one parking area and is located on the advancing track between the two parking areas, judges whether the time duration exceeds preset route time between the two parking areas or not, and generates and issues prompting given when the portable positioning device does not arrive at another parking area within the preset route time if the time duration exceeds the preset route time between the two parking areas. It can be ensured that a guardian can know whether a person who is under guardianship and carries the portable positioning device arrives at the destination prompting area within the preset arriving time or not, and therefore safety information of the person under guardianship can be grasped, and the user experience degree is increased.
