EMERGENCY DETECTION DEVICE, EMERGENCY DETECTION SYSTEM, RECORDING MEDIUM, AND METHOD THEREFOR

摘要

The emergency detection system includes a position information acquisition section, a presumption section, a determination section, and a notification section. The position information acquisition section acquires position information that indicates temporal changes of current positions of a plurality of portable terminals obtained using a GPS. The presumption section presumes a point of emergency occurrence on the basis of the position information acquired by the position information acquisition section. The determination section examines whether or not the point presumed by the presumption section corresponds to an exclusion area, and determines that the point presumed by the presumption section is the point of the emergency occurrence in the case where the point does not correspond to the exclusion area. The notification section notifies the point of the emergency occurrence, which is determined by the determination section, to terminals at a preset destination of the notification.

主权项

1. An emergency detection device comprising:
a position information acquisition section that communicates with a plurality of portable terminals, which detect position information on the basis of radio waves sent from a GPS satellite, and acquires the position information of the plurality of portable terminals; a presumption section that presumes occurrence of an emergency on the basis of at least one of movement situations or stop situations of the plurality of portable terminals, the situations being detected from the position information of the plurality of portable terminals; and a determination section that examines whether or not a point of the occurrence of the emergency presumed by the presumption section corresponds to an exclusion area which is preset and that determines that the emergency occurs at the point of the occurrence in the case where the point of the occurrence does not correspond to the exclusion area.
