Description

Apparatus for alerting fire alarm

FIELD OF THE INVENTION The present invention relates to a fire alarm apparatus, and more particularly, to an emergency rescue center and a device for transmitting a fire alarm to a user when a fire occurs in each residence space.

A typical building fire alarm system detects fire through a wired sensor device and provides fire alarm information to the user. The emergency evacuation system activates evolving equipment such as a sprinkler to detect emergency fire.

Conventional fire alarm technologies use sensor networks and cable networks. This conventional technology recognizes whether or not a fire is occurring through each node of the sensor network, and informs the residents of the apartment complex of the occurrence of the fire through the TV screen through the set-top box disposed in the home.

In addition, the conventional technology notifies the apartment management room of the fire quickly through the cable broadcasting network, and automatically broadcasts the fire occurrence to each household in the apartment complex through the cable broadcasting network. In addition, the conventional technology can automatically notify the related organizations such as the fire department, etc. of the fire occurrence automatically through the wired / wireless network, and can establish an efficient fire alarm system through the set-top box and the cable broadcasting network.

However, this conventional technology only provides first-aid-oriented functions (for example, simple evolution, fire alarm through a TV screen) in case of a building fire, and transmits the fire scene in real time to a fire prevention center such as 119 I can not. Therefore, there is inefficiency that the fire prevention center can not appropriately secure dispatch personnel and equipment depending on the size of the fire, and sends out fire suppression.

Especially, there is a problem that it is difficult to present an escape route in a situation where a fire is in progress to people moving in the building, or to present a rescue route to a fire-fighting house to which a fire occurred, for fire suppression and rescue. That is, such a conventional technique has a problem that it can not provide dynamic fire situation information such as progress of a fire in a building.

For reference, a mobile radio communication network includes, in addition to a base station (BTS), a mobile switching center (MSC), and a home location register (HLR), an access gateway (Access Gateway) Data Serving Node), and the like. In addition, when the wired / wireless communication network 200 is implemented as a wired communication network, it can be implemented as a network communication network, and data communication can be performed according to an Internet protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol).

The fire detector 101 is installed in each residence 100 to detect a fire to generate a fire detection value indicating a fire state value. When the fire detection amount exceeds a preset threshold value, To the camera (102). For example, the fire sensor 101 may include a heat sensor (not shown) for detecting heat and outputting a heat sensing amount as a fire sensing amount, and a smoke sensor (Not shown) that detects the amount of smoke and outputs a smoke detection amount as a fire detection amount, and a volatile component detector (not shown) that detects a volatile component in the air and outputs a volatile component detection amount as a fire detection amount Or more.

The heat sensor can be implemented by a temperature measurement infrared probe and a non-contact temperature sensor, and the measured temperature can be detected as a heat sensing amount. Therefore, when a fire occurs, a high heat sensing amount can be measured.

A smoke detector is a sensor that detects the amount of smoke in the atmosphere, and can measure the smoke amount as a relative value (smoke content in the atmosphere) or an absolute value (smoke amount).

The volatile component detector is a sensor for detecting volatile components in the atmosphere. The amount of volatile component detection may correspond to the ratio of volatile elements in the atmosphere in the living space 100 to the atmosphere. When a fire occurs due to an oil component such as gasoline, the volatile component is detected because the rate of volatile components in the living space 100 is much higher. For reference, these volatile components may include ethanol, higher alcohols, propanol, isobutanol, and methylbutanols.

Therefore, the fire sensor 101 can detect the amount of the detected volatile component when the sensed heat sensing amount exceeds the predetermined heat threshold sensing amount, the detected smoke sensing amount exceeds the preset smoke sensing amount, The camera 102 can transmit a photographing command message to the camera 102, and transmit the sensed heat threshold amount, the smoke sensing amount, and the volatile component sensing amount together.

The camera 102 is installed for each living space 100 in a pair with the fire detector 101. Upon receiving a photographing command message from the fire detector 101, the camera 102 photographs a surrounding image and transmits a fire alarm to the fire alarm server 300). For example, when a fire is detected in the first residence space 100a, a fire command message is received from the first fire detector 101a in the first residence space 100a, The camera 102a can photograph the inside of the first residence space 100a.

The fire detector 101 and the camera 102 are installed in pairs in each residence space 100. The fire detector 101 and the camera 102 may be connected through wired or wireless communication. In case of wired connection, wired communication methods such as Ethernet, universal serial bus, IEEE 1394, serial communication and parallel communication can be used, and furthermore, CAN (Controller Area Network) communication. Also, when wirelessly connected, a wireless communication method such as Bluetooth, home RF, and wireless LAN may be used. The term "bluetooth" refers to short-range wireless communication technology that transmits information such as pictures and voice between portable devices such as a smart phone, an earphone, and a notebook.

For reference, the camera 102 may include a lens assembly, a filter, a photoelectric conversion module, and an analog / digital conversion module. The lens assembly includes a zoom lens, a focus lens, and a compensation lens. The focus distance of the lens can be shifted under the control of the focus motor MF. The filters include an optical low pass filter and an optical low pass filter. And may include an Infra-Red Cut Filter. An optical low-pass filter removes the high-frequency component of optical noise, while the Infra-Red cut filter blocks the infrared component of incident light. The photoelectric conversion module may include an image pickup device such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor). The photoelectric conversion unit OEC converts light from the optical system OPS into an electrical analog signal. The analog-to-digital conversion module may include a CDS-ADC (Correlation Double Sampler and Analog-to-Digital Converter) device. An analog / digital conversion module (not shown) processes the analog signal from the photoelectric conversion unit OEC, removes the high-frequency noise, adjusts the amplitude, and converts it into a digital signal.

The fire extinguisher powder injector 103 and the fire extinguishing gas injector 104 may be installed on the ceiling of each residence space 100. The fire extinguisher powder injector (103) injects fire extinguishing powder into each residence space (100), and the fire extinguisher injector can inject fire extinguishing gas into each residence space (100).

A fire prevention center server is a server operated by an organization that performs fire prevention disaster such as a 119 server. Upon receiving the location information and the surrounding image together with the fire detection report from the fire alarm server 300 of the present invention, it is possible to view the surrounding images in real time and dispatch the firefighter having the corresponding personnel and equipment to the fire site.

A user terminal (not shown) is a terminal used by a user registered for each residence space 100. For example, a smartphone used by a user residing in the first residence space 100a corresponds to a first user terminal. The telephone number of the user terminal is registered in the fire information server, and when the fire occurs in the residential space 100 in which the user himself / herself is registered, the user can be notified of the occurrence of the fire, the surrounding image of the fire scene, have. For reference, the user terminal may be a smart phone, a desktop PC, a tablet PC, a slate PC, a notebook computer, a digital broadcasting terminal, or the like . Of course, it is needless to say that the terminal to which the present invention is applicable is not limited to the above-described type, but may include both terminals capable of communicating with external devices.

For reference, a smart phone is an intelligent terminal that adds a computer support function such as internet communication and information search to a mobile phone, and can install an application desired by the user. The smart phone combines the advantages of a mobile phone and a personal digital assistant (PDA), integrating data communication functions such as schedule management, fax transmission and reception, and Internet access to mobile phone functions. In addition to being able to connect directly to the Internet using wireless Internet, it can be accessed in various ways using various browsing programs. In addition, unlike existing mobile phones, you can install, add, or delete hundreds of different applications (applications) as you like, and you can create your own applications, Can be implemented.

The fire alarm server 300 is connected to the camera 102 installed in each residence space 100 in a wired or wireless communication so that the fire alarm server 300 can detect the surrounding images photographed due to fire detection and the location Information is transmitted to the fire-prevention center server and the user terminal, and evacuation route guidance and fire evolution according to the received fire detection amount can be performed. To this end, the fire alarm server 300 has the same configuration as that of a typical web server in hardware in order to implement the above-described operation, and various types of software such as C, C ++, Jaba, Visual Basic, And includes program modules that are implemented through a language and perform various functions. In addition, it can be implemented using a web server program that is variously provided according to operating systems such as dos, window, linux, unix, and macintosh for general server hardware. Typical examples include a Web site used in a Windows environment, Internet Information Server (IIS), and CERN, NCSA, and APPACH used in a UNIX environment.

3 is a block diagram of a fire alarm server according to an embodiment of the present invention.

The fire alarm server 300 includes a server communication unit 310, a sensing means registration database 350, a heat sensing amount database 360, a smoke sensing amount database 370, a volatile component sensing amount database 380, (320), and a evacuation route notification unit (330). In addition, the fire alarm server 300 may further include a fire extinguishing control unit 340.

The server communication unit 310 supports hardware and software protocols for communicating with the camera 102, the fire prevention center server, and the user terminal, respectively. The server communication units 310 and 320 can perform data communication according to Internet protocols such as TCP / IP (Transmission Control Protocol / Internet Protocol).

The detection means registration database 350 stores the unique number of the fire detector 101 installed for each residence space 100 and the unique number of the camera 102 in the location of the place where the fire detector 101 and the camera 102 are installed (DB) registered with information. For example, the unique number of the first camera 102a installed in the first residence space 100a and the unique number of the first fire sensor 101a are registered in the first residence space 100a, The location information (address, geographical electronic map, etc.) of the second camera 100a is registered, the unique number of the second camera 102b installed in the second residence space 100b and the unique number of the second fire sensor 101b 2 is registered in the residence space 100b and the location information (address, geographical electronic map, etc.) of the second residence space 100b is registered. The unique number of the Nth camera 102n installed in the Nth residence space 100n and the unique number of the Nth fire sensor 101n are registered in the Nth residence 100n and the Nth residence 100n (Address, geographical electronic map, etc.) are registered.

The sensing means registration database 350 may be a hard disk drive, an SSD drive, a flash memory, a CF card, an SD card (Secure Digital Card), a SM A module capable of inputting and outputting information such as a card (Smart Media Card), an MMC card (Multi-Media Card), or a memory stick, or may be provided in a separate device.

The heat sensing amount database 360 is a database in which the heat sensing amount sensed from the heat sensor is stored. The heat sensing amount is a database in which the measured thermal sensed amount from the temperature measuring infrared probe and the thermal sensor of the non-contact temperature measuring instrument is received and stored. Accordingly, when a fire occurs, the temperature of a high heat sensing amount is measured, updated in real time, and stored in the heat sensing amount database 360.

The smoke detection amount database 370 is a database in which a smoke detection amount detected from the smoke amount detector is stored, and the smoke detection amount measured and received from the smoke detector at the time of occurrence of a fire can be updated and updated.

The volatile component detection amount database 380 is a database in which the volatile component detection amount detected from the volatile component detector is stored. The volatile component detection amount measured and received from the volatile component detector at the time of occurrence of a fire can be updated and updated.

The fire fact notification unit 320 can transmit the surrounding image photographed due to the fire detection and the location information of the fire-detected residential space 100 to the fire prevention center server 119 and the user terminal. Therefore, the Fire and Disaster Prevention Center server can view the surrounding images of the fire scene in real time and issue orders for fire and disaster prevention, and it is possible to dispatch firefighters and equipment according to the degree of fire to the fire site. Also, the user in the residence 100 of the fire scene can evacuate by referring to the surrounding image received by the user terminal. For reference, the fire fact notification unit 320 registers the telephone number of the user terminal in advance for each residence space 100, and notifies the user terminal registered in the residence 100 where the fire occurred, Lt; / RTI >

On the other hand, fire escape is not easy in an indoor structure in which a plurality of residence spaces 100 are designed such that a maze is complicated when a fire occurs. For example, it is assumed that the building A is composed of the first, second, third, and fourth residence spaces 100, and that the residence space 100 is complicatedly designed. When a fire occurs in the first residence space 100a and a fire is transferred to the third residence 100, it is assumed that no fire has occurred in the second and third residence 100. [ At this time, the user in the first residence 100a evacuates due to the fire. It is difficult to accurately analyze the fire scene only by the help of the surrounding image from the fire alarm server 300. [ Especially, if the image quality of the surrounding image is bad, it is difficult to know whether the fire occurred or not.

In order to solve this problem, according to the present invention, a evacuation route notification unit 330 for searching for a evacuation route in accordance with a heat sensing amount, a smoke sensing amount, and a volatile component sensing amount of each residence space 100 and transmitting the evacuation route to the user terminal .

The evacuation route notification unit 330 sends a message to evacuate the user to the residential space 100 in which the heat sensing amount, the smoke sensing amount, and the volatile component sensing amount are not detected in each residence space 100 . Such evacuation guidance messages can be provided in various forms such as electronic maps and texts.

Also, the evacuation route notification unit 330 classifies the evacuation route into three levels according to the magnitude of the heat sensing amount, classifies the evacuation route into three levels according to the magnitude of the smoke sensing amount, classifies each of the volatile component sensing amounts into three levels , The heat detection amount, the smoke detection amount, and the volatile component detection amount are summed up, the evacuation route guidance can be performed in the ascending order.

For example, assuming that the size of the heat sensing amount detected in the first housing space 100a is two levels, the smoke sensing amount is two levels, and the volatile component sensing amount is three levels, the total sum value is 7 Become a level

Assuming that the size of the heat sensing amount sensed in the second housing space 100b is one level, the smoke sensing amount is zero level, and the volatile component sensing amount is zero level, the total sum value becomes one level.

When the size of the heat sensing amount sensed in the third residence space 100 is two levels, the smoke sensing amount is two levels, and the volatile component sensing amount is 0 level, the total sum value becomes four levels.

When the size of the heat sensing amount sensed in the fourth residence space 100 is one level, the smoke sensing amount is two levels, and the volatile component sensing amount is zero level, the total sum value becomes three levels.

In this case, the evacuation route notification unit 330 will guide the user to evacuate first to the second residence space 100b having the lowest level of the sum of the levels, and if not, The user is guided to evacuate to the fourth residence space 100, and if not, the user can be guided to evacuate to the third residence space 100 having four levels.

On the other hand, the evacuation route notification unit 330 assigns weights to the heat sensing amount, the smoke sensing amount, and the volatile component sensing amount, and outputs the weighting applied level of the heat sensing amount, the smoke sensing amount, It is possible to perform the evacuation route guidance in the ascending order of the weighted sum values.

For example, it is assumed that the heat sensing amount is given a weight of '5', the smoke sensing amount is assigned a weight of '3', and the volatile component sensing amount is given a weight of '1'. If the level of the heat sensing amount sensed in the first housing space 100a is two levels, the smoke sensing amount is two levels, and the volatile component sensing amount is three levels, the value of "2 (heat sensitivity level) Weighted detection amount weight) + 2 (smoke detection amount level) × 3 (smoke detection amount weight) + 3 (hot feeling amount level) × 1 (volatile content detection weight value) = 10 + 6 + 3 = 19 " . The weighted sum values of the remaining residential spaces 100 can be calculated in the same manner and evacuation route guidance can be performed in the order of smaller weighted sum values.

Such a method can be used as various examples, for example, in the case of a gasoline factory that processes a large amount of gasoline, the risk of gasoline is so great that the gasoline weight can be set higher so that evacuation to a gasoline- will be.

On the other hand, fire extinguishing needs to be different depending on the type of fire. In the case of general fires including wood, paper, cotton, sponge, etc., it is effective to spray water or powder powder and fire. In the case of fire by gasoline, since fire is spread more when water or powder is sprayed, CO2) to suppress the fire by minimizing the oxygen supply.

The fire alarm server 300 of the present invention includes a fire extinguishing control unit 340 to control the fire extinguishing gas injector 104 in the residence space 100 to fire extinguishing gas when a volatile component is sensed, And controls the powder gas injector in the living space 100 so that the powder gas is injected when the volatile component is not detected.

Particularly, the extinguishing spray controller 340 controls the extinguishing gas maximum injection amount that can be injected from the single extinguishing gas injector 104 to be A, the maximum extinguishing powder amount that can be injected from the single extinguishing powder injector 103 B, the volatile component ratio P% in the atmosphere is calculated, the injection amount of the extinguishing gas is determined as A x P%, and the injection amount of the powder gas can be controlled as B x (100-P)%.

For example, if 40% of the volatile components are detected among components of 100% of the atmosphere in the first residence space 100a, the amount of extinguished gas of A × 20% = 0.2A is injected and B × (100-20)% = 0.8 B of the powder gas. This is to spray the corresponding amount of fire extinguishing gas and fire extinguishing powder in correspondence with the situation of the fire according to the cause of the fire.
