As the invention allows for various changes and numerous embodiments, particular embodiments will be illustrated in the drawings and described in detail. However, this is not intended to limit the present invention to specific embodiments, it should be understood to include all changes, equivalents, and substitutes included in the spirit and scope of the present invention.

In describing the drawings, similar reference numerals are used for similar elements. In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

The present invention can easily inform other closed individual spaces of a fire situation occurring in the closed individual spaces.

The fire alarm system using a camera according to the present invention has a camera 30 in each of a plurality of closed spaces, such as a hotel or an officetel.

The fire alarm system using the camera of the present invention is provided with a sprinkler 70 having a normal fire suppression can operate when the fire occurs in the corresponding space to spray water, the fire generated in each closed space It is provided with a management server 60 for integrated management to be stored in other confined spaces.

The camera 30 was further installed in a system having a basic fire suppression and management means to increase the alarm effect.

First, each of the enclosed spaces includes a fire detector 10 for detecting a fire and an alarm 20 for notifying when a fire occurs.

The fire detector 10 and the alarm 20 are installed in each space, the alarm 20 is notified that the fire occurs by operating in all the space of the building at the same time if a fire occurs in other specific space.

The fire detector 10 may use any one of various ones that are typically used to detect a fire.

That is, one or two or more of the smoke sensor, the flame sensor, the temperature sensor used to detect the fire can be installed.

The alarm 20 may be provided with any one or both of a speaker for generating an alarm sound and a warning light flashing a warning light as a means for informing the space in which the fire occurred in a specific space.

The fire detector 10 and the alarm 20 may be configured integrally, but preferably, separately installed. When the fire occurs, the flame rises up and moves along the ?? sheet, and when the alarm is exposed to the flame, it loses its function and the alarm cannot be sounded. Therefore, it is preferable to separate the alarm and install it at the entrance or one side of the door.

The camera 30 is installed in the space to shoot an image only when a fire occurs.

As described above, the camera 30 is installed in each of the enclosed spaces, and may be a work space of a company in need of a private residence or confidentiality of such space. When the camera always photographs and transmits the photographed information to the management server, personal privacy or company confidentiality may be leaked.

Accordingly, the camera 30 only photographs the image of the space where the fire occurred when the fire occurred. The photographed image is transmitted to the management server 60, and the management server 60 transmits the image photographed in the fire generating space to a monitor in another space to notify the fact of the fire.

In addition, if the management of the operation of the camera 30 in the management server can be inadvertently photographed the closed space, whether the operation of the camera should be able to be operated in a closed individual space. To this end, each individual space may be provided with a control means for controlling the operation of the camera, but if the user in each space is left in a state where the camera does not operate, the camera does not operate even if a fire occurs, thus transmitting a fire image. This will not be done.

Accordingly, it is preferable to provide switching means 40 in each sealed space for controlling the camera to operate only when a fire occurs.

The switching means 40 is a function of controlling the driving of the camera, it is preferable to operate at the same time the fire is detected.

Accordingly, the switching means 40 is preferably connected to the fire detector (1) so that when the fire detector detects the fire is connected to supply power to the camera so that the camera can take an image.

The switching means 40 may be modified in various ways, but when the fire detection signal is detected in the fire detector, the switching means 40 may be configured as a relay to which a contact point is connected.

As described above, the fire image detected by the camera can visually check the fact of fire by real-time notification to another space, and more accurately alarm the occurrence of fire, and has a monitor 50 for displaying such image. Doing.

The monitor 50 is installed in each space to display the image taken from the camera installed in the space where the fire occurred.

The monitor 50 may be variously modified, but can be used as a fire alarm for the monitor installed in the hallway.

The management server 60 is a server that notifies the whole fire facts to the entire building, and manages the equipment or facilities related to the fire, as described above, receives the kanji signal detected by the fire detector and delivers to the alarm in another space At the same time as the alarm, the fire video taken by the camera is transmitted to the monitors installed in each space.

Of course, it is preferable to have a storage means for storing the photographed fire image so that it can be used as a fire cause analysis data after the fire extinguishing.

Thus, in order to utilize the image of the fire generating space as the cause analysis data after the fire extinguishing, it is desirable that the camera can be operated for as long as possible. To this end, the camera 30 is preferably resistant to water or fire, and for this purpose, the camera is provided with a heat resistant cover 30c having water resistance (see FIG. 3).

The heat resistant cover 30 is installed to be spaced apart from the camera body by a predetermined interval as shown in FIG. 3 so that heat in the space does not directly contact the camera body.

In addition, if soot is caught in the camera due to a fire, the image cannot be clearly photographed. Accordingly, it is preferable to wash away soot caught in the camera. To this end, the sprinkler 70 sprays water toward the camera 30 so that the camera It is further provided with a retro-reflective portion (70c) to wash off dust and foreign matter.

That is, the soot buried in the camera by lifting up the end of some of the water reflection panels at the bottom of the sprinkler 70 configured as shown in FIG. 4 so as to reversely incline such that a portion of the water divided by the spray nozzle is sprayed toward the camera. Or dust can be washed away.

Of course, as water is sprayed onto the camera surface, the image may be blurred. However, when the water is large enough to cover the camera surface sufficiently, the image may be clearer than the case where soot or dust is stained, thereby obtaining a clear image.

In addition, when the reflector rotates while spraying water, the water is sprayed to the camera only momentarily, so a clear image can be obtained when the water is not sprayed to the camera.

As described above, the present invention can solve the misunderstanding due to the malfunction of the fire alarm according to the alarm through the monitor of the image of the actual fire, not merely a warning of the fact of fire by sound or light.

In addition, as described above, the monitor 50 may not only display an image of the fire generating space but also display an evacuation route.

To this end, the monitor 50 includes an image display unit 50m for displaying a fire image, and an evacuation information display unit 50i configured on one side of the image display unit to display an evacuation route or fire information in text.

The image displayed on the image display unit 50m is a video captured in real time, and the information displayed on the evacuation information display unit 50i may be information on a space where a fire occurred, a degree of fire, an evacuation route, and the like. .
