As shown, the fire detection system of a building according to the present invention is for the fire detection of a building comprising two or more partitioned spaces R1, R2, and R3 that are partitioned, and the partitioned space R1. (R2) (R3) are respectively installed on the ceiling, a plurality of composite fire detectors for wirelessly transmitting the biological signal of the isolated person and the space identification signal identifying the corresponding space when a person is isolated in the space during a fire (100) (100 ') (100) and; and installed in the building, the fire receiving panel 200 for receiving the biological signal and the space identification signal and transmits to the central control center. When (R1) (R2) (R3) is very wide, two or more composite fire detectors may be installed in each partitioned space.

The fire receiving panel 200 is installed at a location where commercial power is applied, that is, a location close to an outlet, and generates an alarm sound when a fire situation occurs and cuts off the power applied to the load end of the building, thereby causing an electrical short circuit in case of fire. To prevent secondary fires. In this case, the fire receiving panel 200 has a built-in uninterruptible power supply (UPS) to enable operation even in the event of a power failure, and further preferably transmits a radio signal to a remote place such as a fire station.

The fire receiving panel 200 is provided with an identification display unit 210 for identifying and displaying a radio signal generated from a specific composite fire detector. Therefore, when a wireless signal generated by a specific composite fire detector is transmitted, the identification display unit 210 displays that the wireless signal is transmitted by the specific composite fire detector, and thus it can be seen that a fire has occurred in a specific space.

The composite fire detectors 100, 100 'and 100 "are installed on the ceilings of the partitioned spaces R1, R2 and R3, as shown in Figs. 111 is coupled to the housing 110, which is located outside the housing 110, the fire detection unit 120 for generating a fire signal (S1) in response to smoke or temperature changes; and the fire signal (S1) A body temperature detector 130 for measuring a body temperature of a person isolated in the corresponding space when the generated temperature is generated, and generating a corresponding body temperature biosignal S2, and a person isolated in the space when a fire signal S1 is generated; A voice sensing unit 140 for sensing the generated voice and generating a corresponding voice biosignal S3, and the space identification signal for identifying the corresponding space from another space when the fire signal S1 is generated; A spatial identification signal generator 150 for generating S4, a fire signal S1, a body temperature biosignal S2, and a voice biosignal S3) and a wireless transmission unit 160 for wirelessly transmitting the space identification code (S4) and a charging power installed in the housing 110 and connected to an external power line, to charge the power applied by the power line And a supply unit 170 and an identification code attaching unit 180 to give an identification code corresponding to the space identification signal S4 to the housing 110.

Here, the body temperature biosignal S2, the voice biosignal S3, and the spatial identification signal S4 are not normally generated, but are interlocked when the fire signal S1 is generated. That is, in a normal situation in which no fire occurs, the body temperature detector 130, the voice detector 140, and the space identification signal generator 150, which may consume energy, are not operated. When a fire occurs, the body temperature detector 130, the voice detector 140, and the space identification signal generator 150 operate to operate the body temperature biosignal S2, the voice biosignal S3, and the space identification signal S4. Will be generated.

The housing 110 and the window 111 are coupled to each other has an explosion-proof function that can safely protect the components disposed inside even in the event of an external fire. To this end, the housing 110, as shown in Figure 3, the housing body 112 made of a metal material, and the heat insulating wall 113 is installed on the remaining portion except the window 111 on the inner peripheral surface of the housing body 112 It includes. At this time, the window 111 is made of heat-resistant glass, and maintains its shape without being damaged for a relatively long time even in high heat caused by fire. Due to the structure of the housing 110 and the window 111, even when a fire occurs in the partitioned space, the metal body and the heat insulating wall 113 of the housing body 112 and the heat insulating flame 113 to the housing 110 inside It will have an explosion-proof function to prevent transmission.

The fire detection unit 120 is located outside the housing 110 to generate a fire signal S1 by sensing a sudden temperature change and smoke when a fire occurs. The fire detection unit 120 is composed of a temperature sensor for sensing the ambient temperature and a smoke sensor for sensing the smoke, and because it is widely used in the art, further description will be omitted.

The body temperature detector 130 measures the body temperature of the person isolated in the space where the fire is generated and generates the body temperature biosignal S2 corresponding thereto. The body temperature sensing unit 130 is provided at the center of the table 131 and the table 131 supported by the PCB 114 mounted on the stepped portion 113a of the heat insulation wall 113 inside the window 111. As an inclined bracket 132 having an oblique inclined surface and a plurality of symmetrically installed on the inclined bracket 132 with respect to the center, in the present embodiment, four tube brackets 133 and inside each tube bracket 133 The infrared sensor 134 is installed, and the body temperature infrared filter 135 is installed at the inlet side of the tube bracket 133 and transmits an infrared wavelength corresponding to a temperature of 30 to 40 ° C.

At this time, the tube bracket 133, in which the infrared sensor 134 and the temperature infrared filter 135 are installed, is installed symmetrically on the inclined bracket 132, thereby measuring the body temperature of a person isolated in the corresponding space in a 360 degree azimuth direction. have.

Meanwhile, even when a fire occurs in the space, the infrared IR filter 135 of the infrared rays generated by the flame transmits only infrared wavelengths in the range of 30 to 40 ° C, that is, similar to the body temperature, so that the infrared sensor 134 senses it. Do it. As a result, whether or not there is a fire, it is possible to know whether there is an isolated person.

The voice sensing unit 140 generates a corresponding voice biosignal S3 by sensing a voice generated by an isolated person in a corresponding space where a fire has occurred, for example, a voice related to a scream or a help request. For example, the voice sensing unit 140 senses a sound corresponding to a frequency corresponding to a scream or groan by an isolated person among sounds generated from the surroundings.

Here, as illustrated in FIG. 3, the voice sensing unit 140 may include a plurality of symmetrically formed holes formed on the sidewall of the housing 110 in the housing 110, for example, a plurality of holes having a diameter of about 1 mm. And a plurality of microphones installed opposite to each other in 110a). At this time, since the interior of the housing 110 is completely sealed, the air heated by the fire cannot be penetrated into the housing 110 through the hole 110a by the air pressure in the housing 110, and thus voice detection is performed. It is possible to prevent the portion 140 from being damaged by high temperature.

The space identification signal generator 150 generates a space identification signal S4 for identifying a corresponding space where a fire has occurred from another space. The space identification signal generator 150 generates a space identification signal indicating that a fire has occurred in a space where a fire has occurred, for example, the third floor 201 room.

The wireless transmitter 160 wirelessly transmits a fire signal S1, a body temperature biosignal S2, a voice biosignal S3, and the space identification signal S4, and transmits the biosignal and the space identification code to the outside. There is no need to install a separate cable for the transmission, thus eliminating the possibility of damage to the cable by fire.

The charging power supply unit 170 is installed inside the housing 110 and connected to an external power line, and charges power applied by the power line. The charging power supply unit 170 maintains a state in which the power applied through the power line is always charged in a normal situation where a fire does not occur, and thus power for operation is supplied even if the building power is cut off by a fire. That is, the charging power supply unit 170 maintains the state in which the power is charged through the usual power line, and even if the power supply is broken in the fire and the power supply is stopped, it is possible to supply power for operation.

The identification code attaching unit 180 provides an identification code corresponding to the space identification signal S4 to the housing 110. The identification code attaching unit 180 assigns an identification code to the biosignals generated from the plurality of composite fire detectors 100, 100 'and 100 "installed in various spaces, and the biosignal is generated from any composite fire detector. The identification code attaching unit 180 is implemented by a plurality of combined switches installed in the housing 110, for example, and a contractor uniquely identifies the specific composite fire detector by manipulating the switch. Give the code

As such, according to the present invention, since all the components for fire detection are built in the housing 110 having an explosion-proof function, information on whether there is an isolated person inside the building while being able to safely operate for a long time even in the event of a fire. Can be provided exactly. As a result, it is possible to enable effective firefighting as well as quick lifesaving.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
