According to an embodiment of the present invention, the present invention comprises: a smart watch for sensing biometric information of a manhole worker working in a manhole and wirelessly transmitting the sensed biometric information by each predetermined transmission period; a repeater for transmitting information on the manhole worker, manhole identification code, and the biometric information received from the smart watch to a central management server; and a central management server for displaying the information on the manhole worker, manhole identification code, and biometric information received from the repeater, and if the biometric information is not received by a predetermined limit time, transmitting a rescue request message including the information on the manhole worker and location of the manhole to a terminal of a manager. According to an embodiment of the present invention, a system for securing safety in a closed space enables a worker in danger to be quickly rescued by monitoring biometric information of a worker working in a closed space in real-time. Also, according to an embodiment of the present invention, it is possible to effectively indicate that the worker is working in a closed space to the outside by using a personal wearable terminal such as a smart watch, or the like. |
