Description

FIELD OF THE INVENTION [0001] The present invention relates to a smart protection helmet system and apparatus for firefighters,

The present invention relates to a smart protection helmet system and apparatus for firefighters, and more particularly to a firefighting helmet system and a firefighting system that detect a danger for the safety of a firefighter, implement a scanning function for effectively suppressing fire and rescue fire at a fire site, And a smart protection helmet system and apparatus for a firefighter that allows the firefighting and firefighting center to organically perform firefighting and disaster prevention operations.

Generally, in case of a fire, it is common to shut off the electricity in the building in order to prevent the electric shock caused by the fire water used in the fire fighting, or to power out due to the fire situation.

In such a case, the dark situation is not a big problem in terms of simply complaining in case of fire suppression. However, in order to find a person who is left unattended in the building due to old people, children, .

Especially, due to the toxic smoke generated in the fire, it becomes more difficult to secure the visibility of firefighters, which is an absolute factor to increase the risk of firefighters 'life maintenance besides the difficulty of firefighters' firefighting and rescue operations. In other words, firefighters are darker due to toxic gas in dark environments, and the sense of direction becomes dull due to smoke, making it difficult to respond to protrusions, and it is almost impossible to find a doorway position or find someone in danger.

In order to solve the above problems, an intelligent fire helmet using a thermal camera and a head display technology has been proposed. However, since the helmet uses a thermal camera, there is a problem that it can not function according to a fire environment There is a number.

  In other words, an infrared thermal camera is a camera that images based on the temperature difference occurring in an object. If the ambient temperature is higher than the temperature of the desired object in a fire scene, or the density of smoke having a certain temperature is high, I have a problem.

  Also, in order for firefighters to fall down during firefighting or to receive help from other firefighters in dangerous situations, it is necessary to know the location of firefighters in order to expedite the exit.

However, existing firefighting helmets are not able to provide information on location recognition and movement, which can detect the position of firefighters, because they have only fire and toxic gas defenses.

Therefore, there is a problem that the fire alarm system can not cope with such situation when the firefighter body abnormality occurs unexpectedly in a poor fire scene.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a firefighting apparatus capable of detecting a physical condition of a firefighter, detecting a position of a firefighter, detecting a moving situation, and providing a firefighter with information about a front, information of a building after firefighting, And to provide a smart protection helmet system and apparatus for a firefighter that provides information in real time and eliminates noise at a fire site to alert the user in advance of necessary voice information and dangerous sounds.

According to an aspect of the present invention, there is provided a smart helmet for a firefighter, comprising: a display unit for viewing the periphery of a helmet and outputting an image signal from an external source; And a sensor for detecting an object on the front side of the helmet while moving in a predetermined space in which the helmet is positioned through a radar sensor to detect an object, And the infrared ray divergence value of the object near the helmet is read by driving the thermal imaging camera unit for infrared sensing when the forward viewing rate through the display unit is equal to or less than the first viewing rate, The scanning unit is driven so that a signal concerning the sensed object is transmitted to the display unit And provides a surrounding image.

As described above, according to the smart protection helmet system and apparatus proposed by the present invention, the position and the movement of the firefighter are detected through the smart protection helmet and the information is provided to the firefighter and the center, They can help and help with fire and rescue.

In addition, according to the smart protective helmet and apparatus for a firefighter of the present invention, precise information about the front is obtained by using an infrared thermal camera and a radar sensor scanning, and a vibration and a position change occurring when using a radar scanning and infrared By correcting using the device, it is possible to correct the sudden movements and changes in the fire scene, and to transmit accurate scene conditions.

Further, the detailed description of well-known functions and constructions that may obscure the gist of the present invention will be omitted. In other words, it should be noted that only parts necessary for understanding the operation according to the embodiment of the present invention will be described, and descriptions of other parts will be omitted so as not to disturb the gist of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a smart protection helmet system and apparatus according to embodiments of the present invention will be described with reference to the drawings. However, it should be noted that the smart protection helmet system and apparatus for firefighters according to the embodiment of the present invention are not limited to or limited to the following description, and thus can be applied to various embodiments based on the following embodiments .

1 is a block diagram of a smart helmet for firefighters according to an embodiment of the present invention. 1, the smart helmet for a firefighter includes a microphone unit 120, a speaker unit 130, a position / movement detection unit 140, a thermal imaging camera unit 150 for infrared sensing, a radar scanning unit 160, A collision avoidance recognition unit 180, a human body information sensing unit 190, a communication unit 200, a display unit 210, a power module view 220, and a controller 230.

The helmet body basically consists of a reinforced helmet structure that can protect the firefighters from the surrounding physical hazards and heat and gas, a tempered glass window, and an air inlet through which oxygen can be injected.

The microphone unit 120 is mounted on a fireman's helmet so as to allow the fireman to transmit voice information such as commands and requests to nearby colleagues or headquarters. The microphone unit 120 can be clearly And the like. In the field of fire, there is a problem in that it can not properly convey the actual words to be transmitted due to various noise and roar. In order to solve this problem, the microphone unit 120 included in the smart helmet for firefighters of the present invention removes unnecessary noise including noise around the fire scene, and inputs only necessary voice information.

The speaker unit 130 performs a function of extracting necessary sound information by inputting surrounding sounds and transmitting necessary sound information to a firefighter and a server of the firefighting and disaster prevention center. There are various sounds in the fire fighting area, and it is difficult for humans to demonstrate their judgment ability and analyze them all. In particular, the sounds directly related to firefighters or related to the collapse of buildings are very important information among various sounds, but they can not be judged by the limit of cognitive ability through human ears. Therefore, the speaker unit 130 provided in the fire helmet for a firefighter according to the present invention performs a function of selectively extracting only a sound indicating a danger after removing unnecessary noise (sound unnecessary for a fire fighting activity) from various sounds. To this end, a high-performance microphone sensor capable of receiving ambient sounds is provided, and a filtering function for eliminating unnecessary sounds and bands from the sound input through the high-performance microphone sensor is performed. Thus, necessary sound information is directly transmitted to the fire fighters, It is transmitted to the server of the disaster prevention center to make more precise judgment.

The position / movement detection unit 140 determines the position of the firefighter through the satellite tracking and the three-dimensional position movement sensor. In general, when a firefighter enters a fire scene or a building, it is inevitable to judge a fire situation by the eyes of a real firefighter, and it is difficult to judge a certain position of the firefighter himself or herself. Especially when smoke is difficult to secure visibility, it has a deadly effect on the sense of direction. Even if the fire-related work depends on a certain degree of light (fire), it is difficult to pay attention to life-saving situations. Especially, the difficulty of sense of direction deterioration and location recognition can be a very important factor directly related to the safety of firefighters. Therefore, the position / movement detection unit 149 provided in the smart helmet for firefighters of the present invention uses a position recognizer and a three-dimensional position movement sensor capable of grasping the accurate position of a firefighter equipped with a helmet. The position recognizer performs the function of recognizing the position of the firefighter, but it is difficult to grasp the precisely moved position in real time during the movement, so that the movement position can be clearly recognized through the three-dimensional position movement sensor.

The thermal imaging camera unit 150 for infrared sensing acquires a thermal image in front of the wearer of the helmet and transmits a thermal image signal to the controller 240. The infrared thermal camera is a device that can quickly and easily measure the temperature of an object by displaying it in a two-dimensional thermal image so that the infrared energy emitted by the object can be easily distinguished by the eye. This camera collects the infrared thermometer and 80,000-300,000 sensors that are commonly used, and displays the measured temperature data at one time in the image image. (Including firefighting activities) to perform the function of recognizing the forward and peripheral information.

2, the radar scanning unit 160 senses a surrounding object while moving or rotating as if scanning a predetermined space where the smart helmet is located using a radar sensor, and transmits a signal related thereto to the control unit 240, Lt; / RTI > In general, it is possible to make a certain degree of smell with an infrared thermal camera, and thus it is possible to construct a life structure. However, when the temperature of the surrounding space is higher than the object to be measured (that is, When the high-density smoke is full, the measurement is difficult. In order to solve such a problem, the radar scanning unit 160 provided in the smart helmet for a firefighter according to the present invention uses a radar sensor technology capable of recognizing an object ahead by transmitting smoke, and is used for a forward situation and a lifesaving structure .

In the present invention, since the radar sensor needs to recognize the frontal situation in real time, the radar sensor is fixed in a certain direction and does not transmit / receive in a certain direction, Rotation) and recognizes the surroundings using the same principle as the aircraft radar. At this time, the correction for the shake is corrected by interlocking with the inertia unit 170.

The inertial device 170 records the shaking motion of the helmet due to the motion of the firefighter, measures the inertia, and corrects the information scanned by the radar scanning unit based on the measured inertia. In the situation where the radar sensor is fixed, the front can be precisely sensed and scanned and displayed on the screen. However, since the location of the radar sensor is the fire helmet of the firefighter, it is constantly shaken up and down and the firefighter moves, which makes it difficult to match the scanned information because the reference point is shaken. In order to solve such a problem, the smart helmet for firefighting according to the present invention recognizes the situation information changed by the radar scanning unit 160 through the inertia member 170 and corrects the scanned information do. This function works in conjunction with the radar sensor.

The collision avoidance recognition unit 180 transmits a danger signal to the control unit 240 when a nearby object is detected within a predetermined distance from the helmet using a proximity sensor. Firefighters usually concentrate on the front if they are engaged in firefighting. If they can not secure visibility because the smoke is full, they may not be aware of the rear and left and right situations, or may collide with nearby objects when turning directions. In case of such a safety threat, a collision detection sensor is attached to the periphery of the helmet so that it can be recognized in advance.

The human body information sensing unit 190 measures a living body signal of a firefighter wearing a smart helmet and transmits a danger signal to the controller 240 when the human body signal is non-ideal. For example, the human body information sensing unit 190 senses at least one of pulse, body temperature, blood pressure, electrocardiogram, and blood flow of the current body of a firefighter through a sensor, monitors the presence or absence thereof, And to inform the server of the fire helmets and firefighting center to prevent the safety of firefighters during fire fighting activities. Especially, there are many cases where firefighters fail to understand the state of the body in a dangerous situation of a sudden fire environment. In this situation, the human body information sensing unit 190 of the present invention checks at least one of pulse, body temperature, blood pressure, electrocardiogram and blood flow of a firefighter to directly recognize the physical condition of the firefighter and a nearby firefighter, Notify the server of the center. In addition, it can detect shortage of oxygen or abnormal condition of fire fighting suit and let the firefighter directly recognize or inform the server of firefighting and disaster prevention center and neighboring colleagues. At this time, the human body information sensing unit 190 can promptly find a fire fighter who has generated an abnormal signal through the position / movement detector 140, and can cope with the danger.

The communication unit 200 supports reception of information between the near helmets through the wireless network and reception of information between the helmet and the server of the firefighting and disaster prevention center. The communication unit 200 allows a firefighter to communicate with a neighboring companion and a server of the firefighting and disaster prevention center, and can receive information on a firefighting site from various sensors provided in a firefighter smart helmet. Generally, when a fire occurs, firefighters often go to a situation where they do not recognize clear information about the firefighting site. In particular, the firefighting activity is put into firefighting situations when the structure of the firefighting site is not clearly recognized. In this case, it is necessary to have a procedure for receiving information after the input by the principle of rapidity of fire fighting activities, but this procedure was impossible with existing fire fighting equipment. Since the smart helmet for a firefighter according to the present invention receives the information of the place and the real-time situation through the display window, it is possible to perform a three-dimensional fire fighting activity. The communication unit implements, for example, a transmission method using a wireless method (3G, WIFI, ZIGBEE, etc.) and has a bidirectional communication function.

The display unit 220 includes a thermal imaging camera unit 150 for infrared sensing, a microphone unit 120, a speaker unit 130, a position / movement detection unit 140, a human body information sensing unit 190, and a communication unit 200 Lt; / RTI > That is, the display unit 220 collects information obtained through a sensor, a radar sensor, an infrared ray camera, or the like, and displays the information in a form recognizable by the firefighter. The display unit 220 implements an additional device in the tempered glass to simply display the beam project or transparent LCD in a color that can easily be recognized by the firefighter so that confusion can be avoided. By allowing the firefighter to recognize the surrounding objects and directions through the display unit 220, the position of the person's name can be grasped more quickly in the rescue. It also alerts the surrounding danger and performs the function of receiving the instructions through the server of the fire fighting and disaster prevention center in real time in text besides voice.

The power module unit 230 includes a microphone unit 120, a speaker unit 130, a position / movement detection unit 140, a thermal imaging camera unit 150 for infrared sensing, a radar scanning unit 160, an inertial unit 170, The collision avoidance recognition unit 180, the human body information sensing unit 190, the communication unit 200, the display unit 220, and the control unit 240. The power module unit 230 includes a battery unit for supplying power, a charging unit, and a circuit protection unit. Since the smart helmet for firefighters has mobility, it is impossible to supply electricity by wire, so the battery is used to supply power. In addition to the regular replacement battery, a charging circuit unit may be additionally provided so that the battery can be recharged when the rechargeable battery is used. The protection circuitry is configured to detect when the battery is charged or when a danger is caused by environmental conditions when using the helmet in a fire scene, and to protect the smart helmet. And information on remaining battery level is displayed in window of firefighter helmet.

The control unit 240 includes a microphone unit 120, a speaker unit 130, a position / movement detection unit 140, a thermal imaging camera unit 150 for infrared sensing, a radar scanning unit 160, an inertial unit 170, At least one of an infrared ray image signal, a radar scanning signal, a voice signal, a position / movement detection signal, and a human body information sensing signal generated from the prevention recognition unit 180 and the human body information sensing unit 190, To be transmitted to the server of the firefighting and disaster prevention center together. The fire department information, the disaster prevention information, and the alarm information are received from the server of the fire fighting and disaster prevention center through the communication unit 200, and the situation of the fire scene is displayed on the display unit 220. In addition, it receives drawing information about a building or a fire place from the server of the fire and disaster prevention center and informs the accurate position where the firefighter is present, and informs about point to be suppressed at once. Then, the position information and the movement information input through the helmet of the firefighter are matched with the drawing information inputted from the server of the fire fighting and disaster prevention center, and the scanning correction information through the radar is received (the inertia information is matched, ), And displays it on the display unit 220 as shown in FIG. Recognizes the infrared ray information through the infrared camera unit 150 for infrared ray sensing, and aligns the forward direction and the camera direction, thereby facilitating movement and fire suppression.

In particular, when the forward viewing rate through the display unit 220 is equal to or lower than the first viewing rate, the control unit 240 drives the thermal imaging camera unit 150 for infrared sensing to read the infrared divergence value of the object around the helmet, When the value is less than or equal to the first divergence value, the radar scanning unit 160 is driven to transmit a signal regarding the sensed object to the display unit 220 to provide a surrounding image to the firefighter.

The infrared ray divergence value of the object is converted into a video signal to be output to the display unit 220 when the infrared ray divergence value of the object around the helmet read through the infrared ray camera thermal imaging camera unit 150 is equal to or larger than the first divergence value, And transmits the peripheral image to the display unit 220 so that the peripheral image is provided to the firefighter.

Here, the first throughput rate of the display unit 220 may be a predetermined value, which is a throughput rate at which the front image can be acquired directly through the display unit 220 in the field of view of the firefighter. The first divergence value of the infrared ray camera unit 150 for infrared sensing may be a preset value as a minimum divergence value that can transmit an object through infrared rays through the infrared camera unit 150 for infrared ray sensing.

Hereinafter, a fire fighting method using the smart helmet for a firefighter according to an embodiment of the present invention will be described.

FIG. 4 is a diagram illustrating an interlocking relationship between a smart fire fighting helmet for a firefighter and a smart fire fighting system according to an embodiment of the present invention. FIGS. 5 to 9 illustrate a driving procedure of a smart helmet system for a firefighter according to an embodiment of the present invention. Fig.

Referring to FIG. 4, the fire fighting and disaster prevention center can provide a shortest path to a fire site, perform traffic control, collect information on a fire site, obtain detailed data on a fire site, Matching between fire scene and firefighter can be done. Fire scene information can be sent to firefighters in real time, information on fire scene conditions can be collected through field personnel and firefighter camera information, and strategies for firefighting activities can be established. The strategy may include fire suppression and lifesaving action plans. It is possible to collect the information inside the building and carry out the fire fighting activities and to notify the firefighter by analyzing the danger situation of the fire scene, for example, the collapse of the building,

5 is a diagram illustrating an initialization and interlocking operation algorithm of a smart safety helmet for a firefighter according to an embodiment of the present invention.

Referring to FIG. 5, the smart helmet for a firefighter according to an embodiment of the present invention includes a sensing and electronic device in addition to an outer case having a protective function and a reinforced window for protecting the face. In step S100, the electronic device sequentially initializes the device and performs step S110 to check whether the entire device has been properly initialized without abnormality (step S120). After the normal initialization, the first step is to send the view information of the site situation to the command vehicle and the disaster prevention center (S130), so that a fire fighting plan can be established in the fire fighting center, and the site situation can be grasped and analyzed. After the normal initialization, it is checked whether the communication with the headquarters and the peer, basic functions of the speaker and the microphone, and the view function of the front are normally performed in the fire fighting activity (S140), and then the fire commander (S150), and performs an initialization step (S160) for performing a fire fighting operation based on the information.

FIG. 6 is an algorithm showing a method of operating a firefighter human body information sensing unit using a smart helmet for firefighters according to an embodiment of the present invention.

6, the body information of the firefighter can be collected in real time during the fire fighting operation development step (S210), and the collected information can be transmitted through the communication unit 200 to other nearby smart helmets or servers of the firefighting center (S220) Here, the body information may be at least one of blood pressure, pulse, body temperature, electrocardiogram, and blood flow. If it is determined that any one of the body information is abnormal (S230), it is checked whether a firefighter wearing a helmet or a server of a firefighter's center receiving the body information can perform a firefighting activity (S240) The control unit 240 transmits a rescue request and / or a firefighter rescue work instruction to the on-scene commander, the firefighter rescue center, and the co-workers (S250). Subsequently, Information about the location of the smart fire helmet that sent the request and / or the firefighter rescue work instruction to the field command, the firefighter rescue center, and peers (S260)

FIG. 7 is an algorithm diagram for operating firefighter location / movement information through a smart helmet for firefighters according to an embodiment of the present invention.

Generally, firefighters are promptly put into the group without specific information because they identify the situation of the fire that is visible when entering the fire scene, analyze it, and put it into the fire site. The present invention is intended to solve the problem that there is no way to know the location of a firefighter in a fire fighting operation once the firefighters enter the inside of the building to some extent. For this purpose, the present invention can obtain the location of firefighters through the method of matching drawings and location information received from smart helmets by receiving drawings, location information and the like from fire prevention room or field command from fire prevention room or field command.

Especially, if you can display the fire status on the supplied drawings and link it with your location, you will be able to fire more quickly, and you will save more time by confirming the direction of travel and distance time during rescue.

For this purpose, when the information of the fire scene is obtained in FIG. 9, the position information can be calculated and matched more precisely through the distance measuring sensor when recognizing the GPS information through the fire helmet and moving.

7, the position information is acquired through the position recognizer and the three-dimensional position movement sensor during the fire operation development step S310 (S320), and the drawing information is received from the server of the firefighter re-center (step S320) In operation S330, the location information obtained in operation S320 is matched with the drawing information of the fire place received in operation S330. If it is determined that the matching result is normal, the user moves to the fire place and performs the disaster prevention activity (S350) If the location identification information is not received or an error occurs in the determination of the location (S360), the request for restoration of the function of the location recognizer is transmitted to the field command unit and the National Emergency Management Agency, When the position recognition function is restored, the position information is reacquired and the fire fighting activity is resumed (S380)

8 is an algorithm diagram for operating view scanning information through a smart helmet for firefighters according to an embodiment of the present invention.

8, by acquiring image information capable of detecting the state of a fire scene through the smart helmet for a firefighter according to the present invention, in addition to a screen that can be viewed under general illumination, there is a dark state caused by a power failure, It is possible to acquire information on the forward direction when the visual field is interrupted due to the obstacle.

To this end, the smart helmet for a firefighter according to the present invention uses an infrared sensing technology and a radar scanning technology to view an image (both image information on the view of a firefighter) of the front of the sight blocking. To do this, we use a thermal camera for infrared sensing, which can read the infrared divergence of all objects and reset the front image. On the other hand, when it is difficult to recognize the temperature (infrared value) of each object due to the fact that the infrared camera can not be used, that is, because the smoke is too thick to transmit through infrared rays or the overall ambient temperature is high and the density is high, To create images that firefighters can perceive.

On the other hand, since these sensing devices are mounted on the helmet of a firefighter, they are susceptible to movement and generate a lot of errors. In order to solve this problem, the change information when the screen is shaken is calculated based on the reference information when the screen is not shaken, and the information to be inputted is corrected to provide continuous image information to the firefighter. To this end, the inertia device is commonly used so that the change value can be precisely applied.

In step S410, the front view ratio is obtained through the display unit 220 in step S410. In step S410, the acquired view ratio is displayed on the front view If it is determined that the acquired infrared radiation is less than or equal to the first through-pass ratio (S430), the infrared camera unit 150 for infrared sensing is driven to acquire the infrared radiation value of the object near the helmet at step S440. If it is determined that the infrared ray divergence value of the object near the helmet acquired through the infrared ray camera part 150 for infrared sensing is less than or equal to the minimum first divergence value capable of transmitting an object through infrared ray at step S450, (S470), and converts the obtained scanning signal into a video signal (S470), and outputs the scanned signal to the display unit 220 so as to provide image information on the surrounding object to the firefighter (S480)

On the other hand, if it is determined in step S450 that the infrared ray divergence value of the object around the helmet acquired through the infrared ray camera unit 150 for infrared sensing is greater than or equal to a minimum first divergence value that can transmit an object through infrared rays, (S452), and outputs the converted image signal to the display unit 220 to provide the firefighter with image information about the surrounding objects (S454)

FIG. 9 is a graph showing a result of a comparison between the anti-collision sensing for recognizing collisions that may occur in the surrounding environment among the various functions of the smart helmet for a firefighter according to the embodiment of the present invention, Which is the hearing system operating algorithm that filters and transmits.

By placing a collision prevention sensor around the helmet and notifying a firefighter when an object or a wall is detected at a predetermined distance or less, it is possible to prevent the firefighter from being injured by nearby objects or walls in an environment difficult to secure visibility of the firefighter, It is possible to prevent the situation from occurring in advance. Proximity sensors can be used as the anti-collision sensors.

In addition, there is a lot of noise in the fire scene, and there is a problem that firefighters are having difficulty in fire fighting activities because of the noise that communication between firefighters is difficult. In order to solve this problem, the smart helmet of the present invention removes unnecessary noise from various sounds at a fire scene to clearly communicate the most important communication message, command and information transmission sound, The sound of buildings collapsing is detected in advance, and firefighters and centers are informed of the safety of firefighters so that firefighting activities can be carried out smoothly.

9, the anti-collision sensor is driven during the fire fighting operation development step S510 (S520). That is, the anti-collision sensor is driven to acquire the sensor value information thereof and transmit it to the sensing information controller, Information related to the generation of the collision information can be transmitted to the sensing information controller. The proximity of the object or access of the creature is judged within a predetermined distance by the collision avoidance sensor (S530), and the access is reported to the speaker or the display unit to display the alarm (S540)

In operation S550, the noise removing and filtering function is performed (S550). That is, the ambient noise is input and the sound is inputted, noise is removed through noise analysis, Voice can be delivered to disaster prevention center and neighboring colleagues. When a sound related to an emergency and an abnormal situation is received through a speaker or a microphone (S560), a step of moving away from the position or performing an emergency action is performed (S570)
