as shown in fig. 9-10, according to the target GPS location information input in the search option input by the activity range subunit, the electronic map marked with the identification mark corresponding thereto is retrieved, and the target GPS location information is located at the center of the display portion of the electronic map;

2. clicking a range defining option, and defining a target area on the electronic map in a touch screen mode to obtain a screen pixel coordinate set of the target area;

3. then converting the screen pixel coordinate set into an actual GPS position information set in the electronic map, namely realizing the demarcation of a target area; when the defined range is wrong or is finished, the defined range can be cleared through the clearing option.

Through the demarcation of home range, can inject student's home range in a specific region, show that the electronic map like in fig. 10 has river, dykes and dams, highway, meadow and dense forest, because there is the risk of falling into water beside the river, and dense forest department has easy lost and does not have the cell-phone signal scheduling problem again, therefore mr can be reasonable inject the scope of demarcation in dykes and dams, highway and meadow department, reduce the risk, improve the security.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present invention.
