Description

{Safety alarm system for confined spaces}

The present invention relates to a safety alarm system for a closed space, and more particularly, to a safety alarm system for a closed space, more specifically, to detect an emergency situation such as a fire or a gas leakage in a closed workplace and to alert the emergency situation by sounding an alarm, And a safety alarm system for occupying a closed space in which a ventilation part is driven so as to secure a field of view so as to evacuate a worker out of a closed work place promptly and safely so that a human accident does not occur.

In general, accidents during work in closed spaces lead to serious disasters and occur repeatedly every year. These disasters are not only loss of life but also economic loss and social issues. Recently, investment in safety management is increasing to reduce the accident rate due to accidents in confined spaces.

In a confined space, there is a problem that it is difficult to recognize the danger situation from the outside because the disaster occurring during the work is not visible from the outside, and there is insufficient education and inspection on the safety rules and safety management. Therefore, fire, explosion, Are continuing to occur.

In addition, there are difficulties in rescue in case of a disaster in a confined space, and there are few second disasters in which rescuers die together.

In order to solve such a problem, conventionally, a safety sensor and an information transmitter for collecting or transmitting safety information are provided in a safety helmet of a worker, and information of a manager is collected and a danger signal is applied to a field manager provided in the field, The signal is transmitted and evacuated.

However, in the conventional safety management system, there is a problem that it can not be detected when there is no worker from a fire or a disaster area, thereby causing damage, and it takes time in the process of receiving information and receiving a danger signal accordingly, There is a problem that it is difficult to evacuate, and when the gas or smoke due to the fire is generated, the view can not be secured.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.
