PURPOSE: A critical situation managing system is provided to prevent danger by transmitting a rescue signal to a receiver through wireless communication in case a critical situation is generated. CONSTITUTION: If a control signal is inputted, a transmitter(10) generates a rescue signal having ID. If the rescue signal is inputted from the transmitter, a plurality of relays(20) generates an alarm, and relays the rescue signal. A plurality of receivers(40) receives and displays a position and information of a person which uses the transmitter for generating the rescue signal. If the rescue signal is inputted from the relay, a managing device(30) grasps an attribute of the corresponding ID, and delivers the position and the information of the person to the receivers through the relay. The transmitter, the relay, the managing device, and the receiver wirelessly perform communication. |
