Abstract: A safety management system according to the present invention includes: a safety management photographing module photographing a limited area; a safety management detection module detecting an object entering the area and information on the object; a safety management shielding module positioned in the area so as to physically control a movement of the object; a safety management alarm module positioned to be adjacent to the area so as to provide a visual or audible warning alarm; a safety management control module receiving object information from the safety management detection module, setting passage priority for the object on the basis of the object information, and controlling the safety management shielding module and the safety management alarm module according to the set priority so as to restrict passage of an object with a next priority or lower.

Abstract: An identification information-calculating type electromagnetic wave transmission/reception-based intrusion surveillance system is proposed. The system is provided to detect an external intrusion by transmitting and receiving an electromagnetic wave signal between an electromagnetic wave signal transmission module and an electromagnetic wave signal reception module, which are installed to face with each other while forming a set in an access surveillance area.
