Description

Firefighting integrated management system using electricity and communication facilities in apartment houses {FIREFIGHTING SYSTEM FOR MANAGING APARTMENT HOUSE USING ELECTRIC AND COMMUNICATION FACILITIES}

The present invention relates to an integrated firefighting management system using electricity and communication facilities of an apartment house, and in detail, by using a fire detection sensor, a fire occurrence in an apartment house is detected, and the detected fire occurrence detection signal is transmitted through a communication facility. While transmitting to the central common control module, fire fighting equipment is quickly controlled through the central common control module to extinguish the fire, and at the same time, it is safe from fire by securing an evacuation space for the household or the common entrance of the fire-prone apartment house. It relates to a fire fighting integrated management system that can promote.

In general, in the event of a fire, a firefighting facility is installed in an apartment house to notify the apartment manager or residents of the occurrence of a fire, and to extinguish a fire at an early stage. These firefighting facilities include a detection sensor that detects heat, smoke, or flame that occurs when a fire occurs, an alarm device that generates a fire alarm through the signal detected through the detection sensor, and a sprinkler device (spring It includes a fire suppression device including a cooler).

Such firefighting equipment detects a fire through a detection sensor, and quickly warns the apartment managers or residents of the fire through an alarm system, and simultaneously extinguishes the fire by spraying firefighters at the point of fire through a fire suppression device. This can minimize the damage to property and people by blocking the spread of fire before firefighters arrive.

However, even if firefighting facilities were installed in apartment houses, if the initial fire suppression failed through firefighting facilities, people who could not evacuate from the fire site were exposed to the fire as it was, resulting in large-scale accidents. Even if a fire door or an evacuation space was built in an apartment house, there was a problem that a person who could not evacuate to the fire door or an evacuation space would be exposed to flames or smoke as it is, resulting in a personal accident.

Prior documents for solving this problem have been proposed in Korean Patent Registration No. 10-1753116 and Korean Patent Publication No. 10-2016-0034872. In these prior literatures, an evacuation space was quickly formed so that people who could not evacuate from the fire site in the vicinity of the fire site can be evacuated to reduce life-threatening accidents.

Republic of Korea Patent Registration No. 10-1753116 is installed on the ceiling of an apartment house and constructs a water air curtain that divides the indoor space of the apartment house by spraying fire water and air at high pressure, through which residents can safely evacuate. By dividing the building into a safety zone, it was possible to temporarily protect residents from fire before fire trucks arrived.

Republic of Korea Patent Laid-Open No. 10-2016-0034872 discloses a housing formed to be detachable from a building, an injection unit disposed along the housing and formed to inject gas, and when fire detection information is input, the gas is used to prevent fire from smoke. The safety of the occupants is promoted by including a control unit for controlling the spray unit so that a protected space is formed.

However, the above-mentioned prior documents only form an evacuation space (safety zone) by forming an air curtain in an indoor space using water air or gas separately from the existing fire door or evacuation space, and due to the nature of the air curtain, it occurs from the fire point. If there is a limit to blocking the inflow of flames or smoke, or if smoke has already flowed into the evacuation space due to the difference between the fire occurrence time and the air curtain formation time, evacuation to the evacuation space contains toxic gases. There were problems such as being exposed to smoke and threatening safety.
