In this paper, we implement the dangerous situation detection system to prevent children from walking on the driveway. The proposed system consists of the iZone device attached to a child's bag or clothes, the iZone application, the external beacon, and the iZone server. The iZone device has an ultrasonic sensor, a LED and a buzzer. The ultrasonic sensor measures fall between driveway and sidewalk. The iZone application for children combines the ultrasonic sensor value received from the iZone device, the child's GPS sensor value, and the surrounding beacon information and send to the iZone server. The protector’s iZone application can provide real-time location tracking information for enrolled children and can receive push messages in an emergency. The iZone server detects if the child is in an emergency and sends the results back to the child's application. Especially, dangerous situation detection module in iZone Server is implemented using a machine learning algorithm. Also, in this paper, we implement the iZone management system. It can change the external beacon information, register a new beacon, and change the GPS information of the dangerous area.
