If the respiratory capacity stored in the respirator is below a certain amount, it is necessary to come down to the ground and switch to another respirator to reenter, but in reality it is almost impossible.

In order to protect people evacuating from the corridor to the evacuation route, such as stairs, the internal fire room maintains a positive pressure of at least 40 Pa compared to the corridor to prevent the smoke from entering the interior. Accordingly, a ventilation system is provided in an evacuation room of an evacuation room such as an all-room, and a conventional ventilation system is installed on a rooftop or basement floor and connected with an air supply fan and an air supply fan for forcibly blowing air to move air to each floor. An exhaust duct is provided. That is, in a manner of supplying additional air for positive air pressure from the rooftop or the basement to all rooms on each floor of the building, when a supply / exhaust fan malfunctions, there is a problem in that all of the rooms' exhaust control functions are lost. In addition, if foreign matter gets stuck or ruptures in some parts of the exhaust duct, air is not normally distributed, so the dehumidification function of the entire room does not work normally.

Therefore, when the smoke control function of the annex is lost, a situation may occur in which smoke is difficult to evacuate properly even in the evacuation route.

This communication method will be apparent to those skilled in the art, and thus a detailed description thereof will be omitted.

The location information output unit is for outputting the received location information. The location information according to the exemplary embodiment may be a sound source message describing a location where the reservoir management apparatus 100 is located. In this case, the location information output unit outputs the received sound source message using an output means such as a speaker. For example, the message [there is an air charging station in the front room of the 3rd floor emergency exit stairs room] may be provided to the air respirator 200 as location information.

As another example, when the location information is indoor coordinate information, the air respirator 200 may provide information according to a navigation function to a destination (set a coordinate according to the received location information as a destination) by comparing with the current own coordinates. There will be. Recently, many attempts have been made to provide a navigation service indoors instead of the GPS method, and actual products will also be released to those skilled in the art.

In this case, the air respirator 200 may select and output one of the strongest possible signal strengths among the wireless signals including the received location information. The strongest signal strength is likely because the distance is closest.

Referring to FIG. 4, which illustrates a processing procedure using location information, when the fire management apparatus 100 recognizes a fire occurrence (S10), broadcasts the location information (S20). That is, since it is not usually necessary to charge the reservoir, it attempts to send the location information when a fire occurrence is recognized.

Air respirator 200 measures the air pressure of the provided air reservoir from time to time, and as a result of the measurement checks whether or not charging is necessary. That is, the air respirator 200 checks the residual amount of air in the provided reservoir, and if the residual amount less than or equal to a preset threshold value (for example, 20%) is recognized, it may be recognized as a pneumatic charge required time.

When the air respirator 200 recognizes the need for air tank air charging, the air respirator 200 selects and outputs the position information having the highest signal strength among the position information received from the air reservoir management devices 100 (S40 and S50).

According to the present embodiment, the firefighter wearing the air respirator 200 may receive a guide for moving to the reservoir management device 100 near the point of time when the fire extinguishing is performed while the fire suppression is performed. You don't have to worry about the amount of air remaining, and you can move to a faster time to recharge or replace the reservoir.

According to an example, the air respirator 200 may differently set the residual amount threshold of the air reservoir to guide the charging according to the strength value of the strongest signal among the signal strengths of the received location information. In other words, by using the information on the strength of the radio signal from the reservoir management device 100, the separation distance with the reservoir management device 100 is predicted, the closer to late (remaining quantity), the sooner (remaining quantity) To guide charging.

In order to be driven as a sub device of such a dehumidification system, the reservoir management apparatus 100 according to the present embodiment provides a dehumidification function by discharging air to the outside (that is, an accessory room) using the air discharge unit 80.

Referring to FIG. 7 illustrating a process thereof, the reservoir management apparatus 100 measures the air pressure in the accessory chamber (S710) and checks whether the measured value is equal to or less than a preset threshold (S720).

The air pressure management device 100 may be provided with air pressure measuring means, or may be in the form of acquiring information on air pressure from an adjacent ventilation system.

If the measured air pressure exceeds the threshold value, the ventilation system recognizes that the air pressure is increased and counts a preset time (for example, 5 minutes, etc.) in order to measure the air pressure again after a predetermined time (S730). .

On the contrary, if it is less than the threshold value it is recognized that the drive of the dehumidification function is required to discharge the air to the accessory room (S740).

According to the present embodiment, since it is installed in an accessory room of an evacuation path equipped with a smoke control function, there is no smoke during fire extinguishing, so it is easy to replace or recharge it. If it occurs, it can maintain the smoke control function of the auxiliary room by playing an auxiliary role.
