Abstract: Smombie (Smartphone+Zombie) is a new word meaning smartphone addict. It is named because it is like a Zombie when walking around while watching a smartphone. The Smombies are increasing in proportion to the spread of smart phones and the development of application functions of smart phones and also accidents are increasing which is becoming a serious social problem. In this study, we propose to add a system that generates a warning sound in the smartphone itself to prevent accidents caused by Smombies. A study on the prevention of accidents caused by Smombies occurred in warning sounds when start walking while watching a smartphone but it is not used well because of the ineffective beep in too wide a situation. In order to compensate for such shortcomings, this study is a study on aggressive prevention system that can prevent danger by ringing a warning sound by checking the distance, access speed and scale between the smartphone and the dangerous places and objects. The Smombie accident prevention system uses a function of sharing a Wireless Sensor Network (WSN), a Global Position System (GPS) and a Geographical Information System (GIS) using a satellite.
