Description

Smart glass for firefighting {SMART GLASS FOR FIREFIGHTING}

The present invention relates to smart glasses for fire fighting. More particularly, it relates to smart glasses for firefighting that can map and output a three-dimensional map including depth information to data sensed by a thermal image sensor.

Firefighter helmets are used to protect the face and head of firefighters at the fire fighting site, and to maintain optimum efficiency and safety in firefighting activities. These firefighting helmets are usually made of a polycarbonate shell for impact resistance. A face protection cover that can be adjusted up and down is installed on the front of the helmet. However, such a conventional firefighting helmet simply protects a firefighter from an external impact, and does not support various requirements necessary at an actual fire site. For example, information such as whether people or animals exist at the scene of a fire must be confirmed by an actual firefighter by penetrating deeply into the scene of the fire and then reporting it to the outside through a separate communication means.

To solve this problem, a thermal imaging camera for firefighting has been developed. A thermal imaging camera senses infrared rays radiated from the body of a person or an animal with a special sensor and outputs an image. In FIG. 1 , an image sensed and output by the thermal imaging camera can be checked. It has the advantage of being able to confirm the existence of people or animals without actual firefighters penetrating deep into the scene of the fire. However, thermal imaging cameras for firefighting are very expensive, bulky and heavy, so it is very inconvenient for firefighters to hold and penetrate the fire scene. . Therefore, in recent fires, a separate manpower who carries only a thermal imaging camera for firefighting and penetrates separately from the firefighters who extinguish the fire is being put together.

In addition, thermal imaging cameras for firefighting can only output whether people or animals are present at the scene of a fire through thermal imaging, and depth information about the specific distance from the firefighter’s current location to people or animals is not covered. Firefighters may experience difficulties in rescue operations and may be at risk of entering a fire scene with insufficient firefighting equipment.

Therefore, it solves the problem of volume and weight and at the same time, it is manufactured in a form that is worn on the firefighter's head, thereby freeing the firefighter's hands and eliminating the need for additional manpower to be input. There is a need for a new and advanced thermal imaging camera for firefighting that can handle all depth information. The present invention relates to this.

However, the present invention is not limited to the embodiments published below, but may be implemented in various different forms, and only these embodiments allow the publication of the present invention to be complete, and common knowledge in the technical field to which the present invention pertains It is provided to fully inform the possessor of the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used with the meaning commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, terms defined in a commonly used dictionary are not to be interpreted ideally or excessively unless clearly defined in particular. The terminology used herein is for the purpose of describing the embodiments and is not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase.

Hereinafter, some embodiments of the present invention will be described with reference to the drawings.

2 is a view showing the exterior of the smart glass 100 for fire fighting according to an embodiment of the present invention.

As shown in FIG. 2 , the smart glass 100 for firefighting according to this embodiment includes a display unit 10 , a first connection unit 20 , a sensor unit 30 , a control unit 40 , and a second connection unit 50 . In addition, although not shown in the drawing, an image generating unit (not shown) formed inside the control unit 40 may be further included. Not only that, it goes without saying that all of the additional components necessary for forming the smart glass 100 for firefighting may be included.

The display unit 10 is spaced apart from the user's field of view by a predetermined distance and outputs a predetermined image.

Since the display unit 10 performs the same role as a monitor on which an image is output, for example, it can be formed by attaching a translucent film to a general LCD lens or displaying an OLED (Organic Light Emitting Diode) panel inside the lens. , as well as any known material may be used. For example, the display unit 10 may be made of the same material as the display unit of a commercially available smart glass.

In addition, the display unit 10 may further include a separate display means (not shown). This is because, if the above-described display unit 10 performs the same role as a monitor, a separate means for outputting an image to the monitor is required. Such a display means (not shown) is formed inside the display unit 10 rather than being formed separately from the display unit 10 because the smart glass is worn on the user's head so that the image can be output as it is. It is preferable to

3 shows a state in which the display unit 10 is spaced apart from the user's field of view by a predetermined distance. However, image identification itself may not be possible. Therefore, it is preferable that the display unit 10 be spaced apart from the user's field of view by at least 3 cm, and the predetermined distance is adjustable through the first connection unit 20 to be described later.

On the other hand, the display unit 10 shown in FIG. 2 has a long rectangular shape. In this case, it is preferable to implement the display unit 100 so that the vertical length of the display unit 100 is at least the vertical length of the user's eyes. . For example, if the vertical length of the user's eyes is 2 cm, if the vertical length of the display unit 100 is 1.5 cm shorter than this, image identification may be difficult due to the limitation of the eye function. In addition, if the vertical length of the display unit 100 is too short, the output image itself will inevitably become smaller, so it will be desirable to have a vertical length that allows image identification.

Of course, the display unit 10 having a rectangular shape is only one embodiment, and the display unit 10 may be implemented in a circular shape like general glasses or in the shape of goggles covering a user's face. That is, the shape of the display unit 10 is not limited.

The first connection unit 20 connects the display unit 10 and a control unit 40 to be described later. Here, the reason for providing the first connection unit 20 separately is that the display unit 10 may be formed to be connected directly from the control unit 40, but the predetermined distance at which the display unit 10 is disposed in front of the field of view may vary depending on the user. Because it is there to control it.

Referring to FIG. 4 , the first connection unit 20 may be provided with an adjustment hole that is adjusted in stages so that the display unit protrudes forward of the fire fighting helmet or retreats to the rear of the fire fighting helmet for the display 10 . The first connection unit 20 may be formed in a multi-stage shape to allow the display unit 10 to adjust a predetermined distance spaced apart from the user's field of view. For example, when the display unit 10 is coupled to the first stage of the first connection unit 20, the predetermined distance spaced apart from the user's field of view may be 3 cm, 4 cm when coupled to the second stage, 4 cm when coupled to the third stage 5 cm, etc. Here, the first stage is based on the stage formed at the position closest to the control unit 40, which will be described later.

Furthermore, the first connection part 20 may be formed of a sliding rail rather than a multi-stage shape. In this case, the first connection part 20 will have to include a separate fixing member so as to be fixed at a position desired by the user, as in the above-described end.

The control unit 40 is a configuration that becomes the main body of the smart glass 100 for firefighting according to an embodiment of the present invention, and includes a sensor unit 30 and an image generator (not shown). First, the sensor unit 30 will be described.

The sensor unit 30 may include one or more of a first ultrasonic sensor, a second ultrasonic sensor, a thermal image sensor, a gyro sensor, and a camera sensor.

More specifically, the sensor unit 30 preferably includes all of a first ultrasonic sensor, a second ultrasonic sensor, a thermal image sensor, a gyro sensor, and a camera sensor. This is because, when an image including depth information is output by an image generating unit (not shown) to be described later, data required for image generation is sensed.

The first ultrasonic sensor and the second ultrasonic sensor can detect a distance from an obstacle including a person or an animal, and includes an ultrasonic transmitter and a receiver to transmit ultrasonic waves forward, and the transmitted ultrasonic waves are reflected by the obstacle. The receiver receives the reflected wave, and it is possible to detect the distance from the time it takes from the time the ultrasonic wave is transmitted to the time it takes to receive the reflected wave to the obstacle.

The thermal imaging sensor senses infrared rays radiated from the body of a person or an animal with a special sensor and outputs an image. In FIG. 1 , an image sensed and output by the thermal imaging camera can be checked.

The gyro sensor can acquire position coordinates corresponding to the user's viewing direction, and can acquire coordinates indicating rotation about the x-axis, rotation about the y-axis, and rotation about the z-axis based on the gravitational acceleration. It is preferable to use a 9-axis gyro sensor.

The camera sensor may acquire an image corresponding to the user's viewing direction, and is the same as a sensor used in a general digital camera.

It is preferable that the sensor unit 30 is formed on the front side of the control unit 40 so that the user can sense the same direction as the direction the user's field of view is facing while wearing the smart glasses 100 for firefighting. That is, the sensor unit 30 should be formed at a position where the user can look forward when the user wears the smart glasses 100 for firefighting.

5 is a diagram separately illustrating the control unit 40 , it can be seen that four holes are formed in the front surface of the control unit 40 . The sensor unit 40 may be formed in this hole, the first ultrasonic sensor in the uppermost hole, the camera sensor in the lower hole, the thermal image sensor in the lower hole, and the second ultrasonic sensor. The sensor can be placed inside the bottom hole. The reason why the first ultrasonic sensor and the second ultrasonic sensor are respectively disposed inside the uppermost hall and the lowermost hall is because the ultrasonic sensor serves to detect the distance, even when the user moves his/her head up and down. In order to detect the distance, including

Here, the arrangement of the sensors inside the hall is to protect the sensor, which is a relatively expensive component, from the outside, and the part that is exposed is to improve sensing accuracy. For example, if the first ultrasonic sensor and the second ultrasonic sensor are disposed inside the controller 40 instead of being disposed inside the hall for sensing, accurate sensing will be difficult. However, if it is disposed inside the hole, since ultrasonic waves can be transmitted/received through the exposed part, the sensing accuracy may be significantly improved.

On the other hand, in the case of the gyro sensor, like other sensors, it may be disposed inside the front hole of the control unit 40, but since the gyro sensor is a sensor that senses angular velocity, which is a change in orientation, there is no need to expose the control unit 40. . In this case, the gyro sensor may be formed inside the control unit 40 .

Meanwhile, the arrangement of the sensors described above is only one embodiment for accurate sensing, and it goes without saying that they may be arranged in a different order. For example, the first ultrasonic sensor may be disposed in the uppermost hole, the thermal image sensor may be disposed in the lower hole, the camera sensor may be disposed in the lower hole, and the second ultrasonic sensor may be disposed in the lowermost hole.

An image generating unit (not shown) generates an image to be output to the display unit 10 by using the data sensed by the sensor unit 30 .

Here, the image generated by the image generating unit (not shown) is different depending on which sensor the sensor unit 30 includes. It will be described below.

When the sensor unit 30 includes only a sensor capable of generating image-related data, for example, a thermal image sensor or a camera sensor, the image generating unit (not shown) may perform Data is created as an image. In this case, the image data sensed by the thermal image sensor or the camera sensor will be output to the display unit 10 as it is.

When the sensor unit 30 includes the first ultrasonic sensor, the second ultrasonic sensor, and the gyro sensor, the image generator (not shown) may include the first ultrasonic sensor with respect to the front that the user is looking at through the display unit 10 . , a 3D map including depth information may be generated by analyzing data sensed by the second ultrasonic sensor and the gyro sensor.

6 is a diagram illustrating data sensed by a gyro sensor. According to the gyro sensor, the position coordinates corresponding to the user's viewing direction may be extracted as (1, 4, 0) indicated by a thick square in the middle.

In addition, referring to FIG. 6 , the position of the obstacle detected by the first ultrasonic sensor is (1, 0 to 10, 0), and the position of the obstacle detected by the second ultrasonic sensor is (1, -10 to 0, 0) can be extracted with

Referring to FIG. 7 , the first ultrasonic sensor calculates the distance to the obstacle and extracts it as a pixel value of (1, 0 to 10, 0), and the second ultrasonic sensor calculates the distance to the obstacle and extracts the distance to the obstacle (1, - It can be extracted as a pixel value of 10 to 0, 0). On the other hand, if the user shakes his head left and right while wearing the smart glasses for firefighting according to an embodiment of the present invention, it is possible to obtain information about obstacles in a wider range in front.

Finally, referring to FIG. 8 , when the y values of the position coordinates of the obstacle are 0 to 10 and -10 to 0, assuming that the distance to the obstacle is 200 cm, a size reflecting 200 cm, which is the distance to the obstacle, may be output.

On the other hand, when the sensor unit 30 includes a first ultrasonic sensor, a second ultrasonic sensor, a gyro sensor, and a thermal image sensor, the image generator (not shown) generates a three-dimensional map including depth information by the thermal image sensor. An image to be output to the display unit 10 may be generated by mapping the sensed data.

In this case, although not separately shown in the drawing, the image output on the display unit 10 is a thermal image sensor showing the scenery shown in FIG. 6 while the user wears the smart glasses 100 for fire fighting according to an embodiment of the present invention. The 3D map shown in FIG. 8 will be superimposed on the image sensed through .

This eliminates the need for users, more specifically firefighters at the scene of a fire, to directly check the specific distance from the current location to a person or animal, thus improving the convenience of rescue activities, This will prevent the risk of entering.

In the above, the sensor unit 30 and the image generating unit (not shown) included in the control unit 40 have been described. Hereinafter, an additional configuration included in the control unit 40 will be described.

The control unit 40 may further include a speaker unit (not shown) on the bottom surface that comes into contact with the head while the user wears the smart glasses 100 for firefighting according to an embodiment of the present invention. The speaker unit (not shown) communicates with the smart glasses 100 for firefighting worn by other firefighters or the central management department in charge of the fire scene through the Bluetooth module or communication module installed inside the control unit 40. can

Furthermore, when the thermal image sensor is turned off, depth information included in the above-described 3D map may be output as sound. For example, depth information included in the 3D map may be output as a sound, such as "there is an obstacle 10 m ahead" or "a person is found 15 m ahead on the right". In this case, the user will be able to confirm the location of the obstacle through the sound output from the speaker unit (not shown) even if the user does not necessarily check the image output on the display unit 10, and the smart glass 100 for firefighting is driven by a battery. Therefore, the thermal image sensor will be turned off and it will be possible to drive for a longer period of time.

9 and 10 , the control unit 40 may include a coupling unit for coupling with the fire fighting helmet. The coupling part 41 may protrude in the form of a clip in the inner direction of the control unit in contact with the firefighting helmet. The control unit may be coupled to the front side end of the firefighting helmet in a clip manner.

The coupling part 40 may include a first anti-skid part 42 made of rubber that is in contact with the inside of the fire-fighting helmet and a magnet 43 positioned adjacent to the first anti-skid part 42 .

Here, the first anti-slip part 41 does not necessarily have to be made of a rubber material, and any material may be used as long as it increases friction so that it does not flow down while being worn on the user's head.

The control unit 40 may include a second non-slip portion 44 made of a rubber material installed in an area in contact with the first anti-skid unit.

The smart glasses 100 for firefighting may not flow down from the user's head even if excessive shaking is induced while being worn on the firefighting helmet by the first anti-skid unit 41 and the second anti-skid unit 44 . In addition, the smart glass 100 for firefighting may have a stronger contact force with the firefighting helmet by the magnet 43 .

Here, the second anti-skid unit 51 also does not have to be made of a rubber material like the first anti-slip unit 41, and any material that increases friction so that it does not flow down while worn on the user's head Anything will be free

On the other hand, since the control unit 40 controls the overall driving of the smart glass 100 for firefighting according to an embodiment of the present invention, it may further include a power ON/OFF button, the above-mentioned Bluetooth module or communication module, a battery, and the like. There will be.

The second connection part 50 is curved in a shape that the other end and one end of the control unit 40 are connected to surround the user's head.

Since the smart glass 100 for fire fighting according to an embodiment of the present invention is worn in a shape that wraps around the user's head, the second connection part 50 has a curved shape accordingly, and can be freely adjusted according to the user's head circumference or wearing shape. It is preferable to form a deformable rubber material.

So far, the smart glass 100 for fire fighting according to an embodiment of the present invention has been described. Firefighters entering the scene of a fire by means of the smart glasses 100 for firefighting are sufficient to extinguish the fire while wearing them and checking only the image output to the display unit 10 or the sound output from the speaker unit (not shown).

Since both hands are free, there is no need for a separate manpower to take thermal images. In addition, since it is possible to output depth information about the specific distance from the firefighter's current location to a person or animal, there is no need for the firefighter to check the specific distance directly. to prevent the risk of entering the fire scene with

On the other hand, the smart glasses 100 for fire fighting may be worn on a fire helmet as shown in FIG. 11 . The smart glass 100 for firefighting should be located inside or outside the face protection cover (g) to be worn on the firefighting helmet. In this case, wearing of the smart glasses 100 may be interfered with by the face protection cover g of the fire helmet. In a fire situation or a fire emergency situation, the smart glass 100 must be removed in an instant. If the angle of the display unit 10 of the smart glass 100 is fixed, the face protection cover (g) of the fire helmet If the angle is also fixed, the smart glass 10 for fire fighting is not compatible with all fire fighting helmets. In order to prevent this problem, the smart glass 10 for firefighting may further include an angle adjustment unit 60 and a relief unit (70 in FIG. 12 ).

The angle adjusting unit 60 may hinge-rotate the control unit and the display unit so that the display is bent to the inside of the fire fighting helmet or opened to the outside of the fire fighting helmet.

As shown in FIGS. 12 and 13 , the display unit 10 may be bent to the inside of the fire fighting helmet by zooming the angle adjusting unit 60 or may be opened to the outside of the fire fighting helmet. At this time, the relief unit 70 automatically adjusts the bending of the display unit 10 according to the angle of the angle adjusting unit 60 when the display unit 10 is bent to the inside of the firefighting helmet by the angle adjusting unit 60 . can alleviate For example, when the display unit 10 is bent to the inside of the firefighting helmet, the relief unit 70 may transform the display unit 10 bent in the 'L' shape to a predetermined angle and date. At this time, the relief unit 70 may deform the angle forward by the angle theta of the display unit 10 is bent inward.

In this case, since the display unit 10 can face forward regardless of how much the display unit 10 is bent, avoid the display unit 10 so as not to interfere with the display unit 10 while wearing a fire helmet. It may be mounted, and may prevent the display unit 10 from stabbing the face by the relief unit.

Accordingly, the smart glass 100 for firefighting according to an embodiment of the present invention has an advantage that a firefighter can quickly attach and detach it to an accurate part of the face in an urgent situation.

In addition, in the present invention, when magnetic materials of the same polarity are formed in the display unit 10 and the face protection cover g of the firefighting helmet, when the user wears the firefighting smart glass 100, the force pushing each other by magnetism generated, and the display unit 10 and the face protection cover g of the firefighting helmet can be positioned so that they do not overlap each other automatically by the angle adjusting unit, and safely and easily without stabbing the user's face by the relief unit 70 can be mounted

In another embodiment, the smart glass 100 for firefighting may be manufactured integrally with the firefighting helmet. In this case, the display unit 10 will be replaced with the face protection cover g of the protective helmet. That is, an image will be output to the face protection cover. In addition, when the smart glass 100 for firefighting according to an embodiment of the present invention is manufactured integrally with the firefighting helmet, detailed description is omitted to prevent duplicate description, but all of the technical features described above may be included.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can realize that the present invention can be embodied in other specific forms without changing its technical spirit or essential features. can understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
