CHILD LOST-PREVENTION MONITORING SYSTEM AND METHOD BASED ON ELECTRONIC MAP

摘要

A child lost-prevention monitoring system and method based on an electronic map. The method comprises the steps of: a child lost-prevention monitoring device (200) displays an electronic geographic map, and receives a first location point and a second location point set by a user on the electronic geographic map; geographic location coordinates of the first location point and of the second location point in the electronic geographic map are acquired so as to form a geographic location coordinate range of a child activity area; a child lost-prevention positioning device (100) transmits the geographic location coordinates to the child lost-prevention monitoring device (200); and the child lost-prevention monitoring device (200) determines whether the geographical location coordinates received are within the geographic location coordinate range of the child activity area and, when the geographic location coordinates are not within the geographic location coordinate range, displays a reminder signal. The system and method helps a guardian to acquire at once geographic location coordinate abnormality information of a child and to start rescue in a timely manner.
