As shown in Figure 1, the conventional safety management system is composed of a situation recognition device and a monitoring server. The situation recognition device includes an image sensor unit, a situation analysis unit, a situation recognition unit, and a transmission unit. The monitoring server can search the database by transmitting the transmitted image and output a warning message for an emergency situation.

The image sensor unit is composed of a general camera, a close-up camera, and a video server, and is in charge of image acquisition. The situation analysis unit consists of image acquisition, object detection, and object tracking, and generates situation information by detecting and tracking objects around the school such as children, adults, and cars.

Situational Awareness is responsible for spatial convergence and application, pattern coordination and learning, accumulated form learning, situational cognition reasoning, and emergency handling. The transmission unit is responsible for transmitting the image captured by the emergency processing module, the situation recognition device number, and the date / time to the monitoring server. The transmission unit is configured by wire or wireless and is transmitted based on TCP / IP.

Monitoring server keeps database of situation information sent from situation recognition device and shows emergency situation as warning message on screen. The administrator can search by time zone in the list and support to print out the shot image.
