The analysis unit AN-S of the server SV may analyze the optimal evacuation route based on the fire alarm FS and the location information (S700). The optimal evacuation route may be an optimal route to the emergency exit EX avoiding the fire FR. In addition, the analysis unit AN-S may analyze the fire alarm FS and the location information in real time to re-search an optimal evacuation route when a fire situation changes. The transmission unit AT2-S of the server SV may transmit the optimal evacuation route to the plurality of route display modules NV and the parties RP (S900). However, this is exemplary and the optimal evacuation route according to an embodiment of the present invention is not limited thereto. For example, when a natural disaster occurs, the optimal evacuation route may be the shortest distance for guiding the plurality of remaining personnel PP to the shelter.

According to the present invention, the persons concerned (RP) can make a concise and clear evacuation announcement to the plurality of remaining personnel (PP) in the building within the initial response time based on the optimal evacuation route. The parties concerned (RP) can identify and share the optimal evacuation route in real time to provide consistent evacuation guidance and joint response to fire. Accordingly, the fire alarm system (FAS) can contribute to the minimization of human casualties.

When the receiver AT1-S of the server SV receives the fire alarm FS, the transmitter AT2-S of the server SV sends an indication signal SG- to each of the plurality of path display modules NV. 3) can be transmitted (S800). When each of the plurality of route display modules NV receives the display signal SG-3, it may display an evacuation route based on the optimal evacuation route (S1000). Each of the plurality of path display modules NV may include a laser guide lamp. However, this is exemplary and each of the plurality of path display modules NV according to an embodiment of the present invention may include an LED induction lamp.

The fire alarm system FAS may provide the optimal evacuation route to the plurality of remaining personnel PP through the plurality of route display modules NV according to the flowchart shown in FIG. 4 .

According to the present invention, each of the plurality of remaining personnel PP may move to the emergency exit EX along the optimal evacuation route indicated by the plurality of route display modules NV. The optimal evacuation route may include a shortest evacuation route by avoiding a fire (FR) point. Each of the plurality of remaining personnel PP can safely evacuate within the initial response time through the optimal evacuation route. Accordingly, the fire alarm system (FAS) can contribute to the minimization of human casualties.

6 is a flowchart illustrating a method of operating a fire alarm system according to an embodiment of the present invention, and FIG. 7 is a diagram illustrating a rescue process according to an embodiment of the present invention. Components described with reference to FIGS. 1 and 2 are denoted by the same reference numerals, and descriptions thereof will be omitted.

1 to 7 , a fire alarm system (FAS) may be installed and used in a building. For example, when a fire FR occurs in a building, the processing unit CC-S of the server SV may calculate location information of each of the plurality of terminals MD based on the positioning signal MS. (S500). The server SV may be connected to the monitoring server MO. The transmitter AT2-S may transmit the location information to the first monitoring receiver AT1a-M (S1100).

The second monitoring receiving unit AT1b-M may receive the location information of the party of at least one party RP-1 among the parties RP (S1200). The person concerned (RP-1) may be a rescuer. For example, the rescuers may include firefighters and police officers.

The monitoring analysis unit AN-M may calculate an optimal entry path ER based on the location information and the related person location information (S1300). The optimal entry path ER may be the shortest distance for rescuing a plurality of remaining personnel PP in the building.

The monitoring transmitter AT2-M may transmit the location information, the location information of the person concerned, and the optimal entry path ER to the parties RP (S1400). Each of the parties (RP) may be provided with the location information, the location information of the parties, and the optimal entry path (ER) through a monitoring app (APP) or a monitoring web (WEB). The fire alarm system FAS may provide an optimal entry path ER to the person RP-1 according to the flowchart shown in FIG. 6 .

According to the present invention, the person concerned (RP-1) recognizes the location of the plurality of remaining personnel (PP) through the location information before entering the building where the fire (FR) has occurred, so that the plurality of remaining personnel (PP) can be easily rescued. The person concerned RP-1 may easily access the plurality of remaining personnel PP based on the optimal entry path ER and perform a rescue. A fire alarm system (FAS) can minimize human damage caused by a fire (FR). In addition, when the person concerned (RP-1) enters the building, the persons concerned (RP) receiving the location information of the person concerned tracks the location of the person concerned (RP-1) in real time, and a situation occurs to the person concerned (RP-1) quick action can be taken. A fire alarm system (FAS) can easily protect personnel (RP-1) who have entered for rescue.

Although the above has been described with reference to the preferred embodiment of the present invention, those skilled in the art or those having ordinary knowledge in the technical field will not depart from the spirit and technical scope of the present invention described in the claims to be described later. It will be understood that various modifications and variations of the present invention can be made without departing from the scope of the present invention. Accordingly, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
