Description

Intelligent Fire Prevention System {System for prevention of fires}

The present invention relates to a fire detection and evacuation system, and more particularly, to detect and extinguish a fire when a fire occurs in a ship, a building, a subway, various facilities, etc. The present invention relates to an intelligent fire protection system that minimizes human injury by establishing a guide system so as not to evacuate to the gas area.

In general, when a fire occurs, a system for protecting a valuable life and property by responding quickly and accurately is a fire prevention system, and an emergency response device is added to the disaster prevention system.

In particular, high-rise buildings with high floating population, such as apartments, department stores, multiplex cinemas, subway stations, and public facilities, can respond quickly to fires to protect property and human life. In addition, a damper (or a fan) is installed, and when the fire is detected, the disaster prevention device is driven by driving the initializing device corresponding device.

As described above, a conventional fire prevention system for driving disaster prevention devices by driving an initializing device counteracts a plurality of fire detectors (or fire detection sensors) that detect heat or smoke to generate fire information and transmit it to wired or wirelessly. And at least one relay device for receiving the fire information input from the plurality of fire detectors, and a comprehensive control device for analyzing the fire information received from the relay device to display the location of the fire when detecting the fire and generating a fire alarm. It includes.

On the other hand, the above-mentioned fire detector (or fire sensor) is installed in a plurality of places inside the building to detect the fire, the relay device is installed on each floor of the building to receive the fire information input from a plurality of fire detectors In addition, the general control system is installed in the management room that controls and manages the entire building to monitor the occurrence of fire while transmitting and receiving fire information with the relay device in real time. If a fire breaks out, the relay device and the general control device respectively indicate the place where the fire occurred, and issue a fire alarm to notify the residents and the building managers in the building where the fire occurred and the public offices connected as necessary. .

However, the conventional fire protection system configured as described above has many problems as follows.

First, when the fire retardant is detected and judged to be a fire through communication between the relay and the comprehensive control device, the manager or external person who manages the comprehensive control device manually controls the fire retardant. By extinguishing the problem, the time taken from the occurrence of a fire to the operation of the initializing material countermeasure device becomes long. In addition, since the fire is suppressed according to the control operation of the integrated control device, it takes a long time from the occurrence of the fire to the operation of the initializing material counterpart.

Secondly, when an error occurs in the communication device that transmits and receives data communication between the relay device and the integrated control device due to the fire, data transmission for the fire occurrence is impossible and thus an initial fire suppression is impossible.

Third, because of the power supply method by wire, when the power supply is disconnected or lost due to a fire or by other factors, the power supply is impossible and the disaster prevention system itself does not operate.

Fourth, people who are inside the building during sudden power outages and fires in subway stations, department stores, various public facilities and apartments, which are crowded with large floating populations, cannot find the evacuation route due to the complex structure of the building. Since it is difficult, it has the disadvantage of causing huge casualties at the moment.

Fifth, unlike a power failure in an apartment, if a fire breaks out or gas leaks into the room, it cannot be properly and effectively notified of the occurrence of the fire due to a sound transmission barrier such as a soundproof wall at the fire site. As a result, there is a problem of inadvertently being damaged.

Sixth, even in special environments such as underground shopping malls and underground buildings, there is no intelligent system that analyzes and copes with the toxic gas over time even though the casualties increase due to the generation of smoke, that is, toxic gases rather than fire. .

Disaster prevention system according to an embodiment of the present invention is a plurality of fire detection sensor 10 and the motion detection sensor 12 installed in the interior of the building, receiving the detection signal from the sensor to extinguish the fire and evacuate the distress people safely The controller 14 to enable the alarm, the alarm generator when the fire occurs, and the alarm generator 16 for transmitting the announcement broadcast so that the distress people are not evacuated to the fire area, water or chemicals in the fire area Fire suppression unit 18 for extinguishing the fire by spraying the fire, and induction light generating unit 20 for selectively turning on or off the induction light.

Referring to FIG. 1, the fire detection sensor 10 is configured to be installed in various places inside or outside the building to accurately identify the location of the fire and transmit it to the controller unit 14. At this time, the fire detection sensor 10 is a composite detector is configured to compositely detect heat or smoke as well as the flame when a normal fire occurs, and adopts RS 485 communication. In addition, the fire detection sensor 10 can be used in conjunction with the existing detector.

The motion sensor 12 is a sensor for detecting in real time the motion state of all the distress people in the interior / exterior of the building (i.e., the fire area or the adjacent area) and transmitting it to the controller unit 10. This is to allow evacuation to a stable place without evacuating to the occurrence area. In this case, the motion detection sensor 12 may recognize a location by interworking with a ZigBee network in an indoor of a building, and may recognize a location by a GPS outdoors. In addition, the location of the distress can be recognized by mapping latitude / longitude of the map image, interlocking a database for POL, or interlocking a WMS (Web Map Service) server.

When the controller 14 determines that a detection signal is input from the fire detection sensor 10 and the motion detection sensor 12, preferably a detection signal indicating that a fire has occurred is input from the fire detection sensor 10. When a signal is detected in real time to detect the movement of the distress in the building from the motion sensor 12 in real time to operate the alarm generating unit 16, fire suppression unit 18 and the induction light generating unit 20. That is, the controller unit 14 operates the alarm generating unit 16 to output an alarm sound and a guide broadcast so that the distressed people do not evacuate to the fire occurrence area, and operates the fire suppression unit 18 to the point where the fire has occurred. Inject water or chemicals, etc., by operating the induction light generating unit 20 to turn off the induction light to the area where the fire occurred, and to turn on the induction light toward the other emergency exit so that the distress people can evacuate safely. The control operation of such a controller unit 14 will be easily understood by the detailed description of FIG. 2 to be described later.

The alarm generation unit 16 is an apparatus that generates an alarm sound in response to the control signal output from the controller unit 14 and transmits a guide broadcast so that the distress people may be evacuated to a safe area. That is, the alarm generating unit 16 not only outputs an alarm sound such as a siren, but also guides the broadcaster to prevent the distressed people from moving to the fired area (for example, as shown in FIG. 3, moving toward the emergency exit B). Do not do it. "

The fire suppression unit 18 is a device for extinguishing a fire by spraying water of high pressure or spraying chemicals or the like on an area where a fire occurs according to the control operation of the controller unit 10. In this case, the fire suppression unit 18 may use a fire suppression apparatus that is generally widely used. In the intelligent fire protection system of the present invention, the inventors have registered a patent registration number 10-0441310 dated July 13, 2004. (Invention: Fire Fighting Mist Device) or Patent Registration No. 10-0470762 registered on January 31, 2005 (Inventive name: fire extinguishing nozzle), and patent registered on April 16, 2008 It is preferable to use the fire suppression apparatus described in registration No. 10-0824221 (name of the invention: automatic fire extinguishing nozzle).

The induction light generator 20 is a device for selectively lighting or blinking the induction light in response to a control signal output from the controller 10. That is, the induction light generating unit 20 lights or flashes the induction light installed in the area where the fire does not occur except for the induction light installed in the area where the fire has occurred, so that the displaced people can be evacuated to the safe area without evacuating to the fire area. Device. At this time, the induction light generating unit 20 may use an induction light that is installed in the interior of the building, if necessary, may be used as shown in FIG.

Referring to FIG. 5, the induction light generating unit 20 of the present invention is an infrared laser induction light device, and includes an emergency power supply unit 200, a laser generating unit 202, and a convex lens 204. Specifically, in the event of a fire, the laser generator 202 emits laser light having a wavelength of 532 to 1064 nm and passes through the convex lens 204 to play the same role as an induction lamp to the wall 300 or a special device, which is usually 2 to 3 m ahead. Examine the signs of induction to make it easier for the distress to identify them. In this case, the emergency power unit 200 may use an emergency generator, and may use a battery as necessary.

Hereinafter, an operation state of the intelligent fire protection system of the present invention configured as described above will be described in detail with reference to FIGS. 2 to 4.

First, the controller 14 illustrated in FIG. 1 determines whether a detection signal indicating that a fire has occurred is input from the fire detection sensor 12 in step 100. If it is determined in step 100 that a fire has occurred, the controller unit 14 checks the location of the fire detection sensor 10 installed in any region of the fire sensor 10 installed in the building in step 102. If it is determined in step 102 that the fire region has been identified, the controller 14 drives the alarm generator 16 to output an alarm sound such as sirens. At the same time, the fire extinguishing unit 18 is driven in step 106 to spray water or chemicals in the area where the fire has occurred, and the induction light generating unit 20 is driven in step 108 to light or flash the induction lamp inside the building. .

On the other hand, the controller 14 performs the above-described step 102 and at the same time whether the motion detection sensor 12 is operating in step 110, specifically detects and outputs in real time the movement status of the distress in the interior of the building Check if there is a detected detection signal. If it is determined in step 110 that the detection signal output from the motion detection sensor 12 is input, the controller unit 14 outputs a guide broadcast by driving the alarm generator 112 in step 112, and generates an induction light in step 114 Drive the unit 20 to turn off the induction lamp installed in the area where the fire occurred. In addition, the controller 14 analyzes the dangerous area in real time according to the flow of flame and smoke in step 116, and sets a real-time evacuation path in step 118.

At this time, the alarm generating unit 16, as shown in Figure 3 "If you evacuate to the emergency exit B will move to the area where the fire occurred, please move to the emergency exit A and emergency exit C." Or "Disasters do not go to exit B, go to the rest of exit." It outputs announcements to prevent distress people from moving to the area where the fire occurred. In addition, the induction light generating unit 20 also turns off the induction light of the emergency exit B installed in the area where the fire occurs as shown in FIG. 3 and simultaneously turns on or flashes the induction light of the emergency exit A and the emergency exit C.

In this case, when it is determined that there is no detection signal input from the motion detection sensor 12 in step 110, the controller 14 performs steps 104, 106, and 108 described above. That is, the alarm generator 16 generates only an alarm sound such as siren, and the induction light generator 20 lights or flashes all of the induction lamps installed in the building.

As described above, the present invention outputs the above-mentioned announcement as shown in FIG. 3 and also turns off the induction lamp installed in the area where the fire has occurred, thereby preventing the distressed people from evacuating toward the emergency exit B, the area where the fire occurred. Damage can be prevented. However, conventionally, as shown in FIG. 4, since the announcement or guidance lamps of the present invention are not selectively turned off, the distressed people are not only emergency exit A and emergency exit C, but also evacuation toward emergency exit B, which is the area where the fire has occurred. It is triggered.
