Description

Fire detection type parking guidance camera and method of operation therefrom

[0001] The present invention relates to a technology for a parking guidance camera, and more specifically, to a fire-detecting parking guidance camera and a method of operation thereof.

[0002] Existing thermal imaging cameras focus solely on outputting temperature data, so most rely on external PCs for additional computations required for monitoring.

[0003] In addition, as the forms and arrangements of targets to be monitored have become diverse and complex, there is a demand in the market for the ability to monitor complex types of targets.

[0004] Meanwhile, a thermal imaging camera is a device that collects infrared wavelengths emitted from the unique radiant energy generated by an object and converts the output electrical red signals into images or videos that humans can perceive; it is widely used for various purposes, including surveillance, industrial, research, medical, and military applications.

[0005] In particular, thermal imaging cameras are widely used in fire surveillance and monitoring systems due to their advantage of being able to acquire images representing the two-dimensional temperature distribution of an object; accordingly, various studies are being conducted on fire surveillance, fire prediction, and fire alarm systems utilizing thermal imaging cameras.

[0006] Meanwhile, in the case of large parking lots, they consist of parking areas with multiple parking spaces (parking blocks) and passageways between the parking areas, and parking guidance cameras are installed.

[0007] Conventional parking guidance cameras detect empty parking spaces and parking spaces where vehicles are parked and illuminate a light source of a different color.

[0008] However, parking guidance cameras had a problem in that they could only detect vehicles and could not detect fires.

[0010] (Patent Document 2) Republic of Korea Registered Patent No. 10-2548238

[0011] (Patent Document 3) Republic of Korea Published Patent Application No. 10-2019-0111357

[0012] (Patent Document 4) Republic of Korea Registered Patent No. 10-2288903

[0013] The present invention was devised to solve the aforementioned conventional problems and aims to provide a fire-detecting parking guidance camera capable of simultaneously providing parking guidance and fire detection.

[0014] The present invention provides a fire detection type parking guidance camera comprising: a case (100) fixed to a frame (50); a vision camera (200) installed on the bottom surface of the case (100); a thermal imaging camera (300) installed on the side of the case (100); and a light source module (400) disposed in the case (100) and emitting a light source to guide a vehicle.

[0015] The above case (100) may include a mount case (110) installed on the frame (50), an upper case (120) assembled to the mount case (110), a lower case section (130) spaced apart from the lower part of the upper case (120) and on which the vision camera (200) is installed, and an inner case section (140) extending upward from the lower case section (130), mounted and assembled to the upper case (120), and on which the thermal imaging camera (300) and light source module (400) are installed.

[0016] The vision camera (200) is positioned in the lower case part (130), and the thermal imaging camera (300) is positioned in the inner case part (140) and can be installed to penetrate the light source module (400).

[0017] The above thermal imaging camera (300) may include a thermal imaging case (330) and a thermal imaging sensor (310) disposed inside the thermal imaging case (330).

[0018] The light source module (400) may include a light source body (410) formed of a material that can transmit light and surrounds the inner case part (140), a light-emitting element (420) that projects at least two types of light sources onto the light source body (410), an inner reflective coating (430) that is coated on the inner surface of the light source body (410) and reflects light, and a camera hole (440) formed to penetrate the light source body (410) and assembled so that the thermal imaging camera (300) penetrates it.

[0019] The above thermal imaging case (330) can pass through the camera hole (440) and be exposed outside the light source body (410).

[0020] First, since the present invention integrates a vision camera for detecting parking and a thermal imaging camera for detecting fire, it has the advantage of being able to provide parking guidance and fire detection simultaneously.

[0021] Second, the present invention has the advantage of being effective in the early extinguishing of fires because it can detect a fire through a thermal imaging camera even before a fire extinguishing device, such as a sprinkler, is activated.

[0022] Third, since the present invention transmits a fire warning through a speaker placed in the case, it has the advantage of effectively making people in the vicinity aware of the location of the fire.

[0023] Fourth, the present invention has the advantage of effectively recognizing the location of a fire because it provides the ID of the thermal imaging camera that detected the fire to the server.

[0040] FIG. 1 is an example diagram of the installation of a fire-detecting parking guidance camera according to a first embodiment of the present invention, FIG. 2 is a perspective view of the fire-detecting parking guidance camera shown in FIG. 1, FIG. 3 is a front view of FIG. 2, FIG. 4 is a bottom view of FIG. 2, FIG. 5 is a front view of the case shown in FIG. 3, FIG. 6 is an enlarged cross-sectional view showing the installation structure of the first thermal imaging camera shown in FIG. 5, FIG. 7 is a front view of the light source module shown in FIG. 2, and FIG. 8 is a bottom view of the light source body shown in FIG. 7.

[0041] The fire detection type parking guidance camera according to the present embodiment includes a case (100) fixed to a frame (50), a vision camera (200) installed on the bottom surface of the case (100), a thermal imaging camera (300) installed on the side of the case (100), and a light source module (400) disposed in the case (100) and emitting a light source to guide a vehicle.

[0042] In this embodiment, the vision camera (200) uses a fisheye lens, and can capture a wide area.

[0043] The above vision camera (200) can photograph multiple parking spaces. In this embodiment, the parking lot includes multiple parking spaces (11)(12) where a vehicle (1) is parked, and a passageway (13) through which the vehicle moves.

[0044] The above frame (50) is placed in the passage (13) through which the vehicle (1) moves.

[0045] In this embodiment, the vision camera (200) can detect a parking space of 3 columns and 2 rows.

[0046] In this embodiment, the vision camera (200) can photograph three parking spaces arranged on both sides of the passageway (13).

[0047] Among the above parking spaces, a parking space where parking is impossible is defined as an impossible parking space (11), and a parking space where parking is possible is defined as a possible parking space (12).

[0048] The above-mentioned impossible parking space (11) refers to a parking space where a vehicle is parked or a parking space where parking is impossible due to the installation of parking cones, etc. In cases where water leakage occurs in the underground parking lot, the floor is repainted, or parking is impossible, parking cones, etc. are installed to prevent the entry of vehicles.

[0049] Parking cones and vehicles can be detected in the image captured by the above vision camera (200).

[0050] The vision camera (200) comprises a vision case (210), a vision camera module (220) positioned downward from the vision case (210), and a vision cover (230) assembled to the vision case (210) to cover the vision camera module (220).

[0051] The above case (100) includes a mount case (110) installed on the frame (50) and a camera case assembled on the lower part of the mount case (110).

[0052] The above camera case includes an upper case (120) assembled to the mount case (110) and a lower case that is inserted into the inside of the upper case (120) and mounted thereon before being assembled.

[0053] The lower case is spaced apart from the lower part of the upper case (120) and includes a lower case section (130) on which the vision camera (200) is installed, and an inner case section (140) that extends upward from the lower case section (130), is mounted and assembled on the upper case (120), and on which the thermal imaging camera (300) and light source module (400) are installed.

[0054] The above case (100) further includes a case catch portion (150) that protrudes upward from the mount case (110) and forms a mutual catch with the frame (50).

[0055] The vision camera (200) is installed in the lower case part (130), and the thermal imaging camera (300) is installed in the inner case part (140).

[0056] The light source module (400) is arranged to surround the inner case part (140), and provides the driver with information on whether parking is possible through a plurality of light sources.

[0057] The above-described mount case (110) includes a mount upper portion (111) that is in close contact with the bottom surface of the frame (50), a mount lower portion (112) that is in close contact with the camera case, a mount inclined portion (114) formed so that its cross-section extends downward from the mount upper portion (111), and a mount circumferential portion (115) that extends downward from the bottom of the mount inclined portion (114) and is connected to the mount lower portion (112).

[0058] The above-mentioned mount upper portion (111) is formed in a parallel manner and, when viewed from the top, is formed in a circular shape. A mount hole (113) is formed that penetrates the above-mentioned mount upper portion (111) in the vertical direction, and a cable is inserted into the interior of the case (100) through the mount hole.

[0059] In this embodiment, the mount inclined portion (114) is formed in a truncated cone shape, and the mount circumferential portion (115) is formed in a ring shape. The mount inclined portion (114) is a truncated cone shape in which the cross-section increases toward the lower side.

[0060] The mount lower part (112) is formed by being bent radially inward from the bottom of the mount circumference part (115) and assembled with the upper case (120).

[0061] The upper case (120) comprises an upper case upper side surface (121) that is in close contact with the mount lower part (112), an upper case lower side surface (122) positioned below and opposite to the upper case upper side surface (121), and an upper case outer surface (125) connecting the upper case upper side surface (121) and the upper case lower side surface (122).

[0062] The upper side surface (121) of the upper case is positioned opposite to the lower mount portion (112).

[0063] The upper case (120) has an upper case opening surface (123) formed in the vertical direction.

[0064] The upper case (120) is formed in a ring shape overall, and the lower case can be inserted into the upper case opening (123) and mounted on the upper case upper side surface (121) of the upper case (120).

[0065] The lower case can be assembled and fixed to the upper case (120).

[0066] The lower case above is formed in the shape of a truncated cone with a pointed lower end.

[0067] The outer surface of the inner case part (140) is formed as a conical curved surface.

[0068] The light source module (400) is formed to surround the outer surface of the inner case part (140).

[0069] The outer ends of the upper case (120) and the inner case part (140) are spaced apart, and the outer ends of the lower case part (130) and the inner case part (140) are spaced apart.

[0070] That is, the outer end of the inner case part (140) is positioned further inward than the outer edge of the upper case (120) and lower case part (130), and an installation space (148) is formed on the outer side of the inner case part (140) in which the thermal imaging camera (300) and light source module (400) are installed.

[0071] The inner case portion (140) includes an outer surface (145) in the shape of a truncated cone with a pointed lower end. The outer surface (145) is located radially inward from the upper case outer surface (125).

[0072] The outer end of the upper case outer surface (125) and the upper end of the outer surface (145) form an installation gap (a).

[0073] It includes a thermal imaging upper part (143) that is bent radially outward from the top of the inner case part (140) and mounted on the inside of the upper case (120), and a thermal imaging body part (144) that extends downward at an angle from the thermal imaging upper part (143) to form a truncated cone shape.

[0074] The thermal imaging upper part (143) is formed in a ring shape, and its outer diameter is formed to be larger than the inner diameter of the upper case opening (123), thereby allowing it to be mounted inside the upper case (120).

[0075] The upper part (141) is connected to the lower side of the upper case (122), and the lower part (142) of the inner case part (140) is connected to the upper side of the lower case part (130).

[0076] The above thermal imaging body part (144) forms the above outer surface (145).

[0077] After the above thermal imaging upper part (143) is mounted on the upper case (120), it can be fastened and fixed.

[0078] The upper end (141) of the outer surface (145) is exposed to the outside through the upper case opening (123).

[0079] The lower case part (130) comprises a vision upper part (131) formed by being integrally coupled to the lower end (142) of the inner case part (140), a vision lower part (132) spaced apart from the vision upper part (131) and having the vision camera (200) installed thereon, a vision outer part (135) connecting the vision upper part (131) and the vision lower part (132), and a vision camera hole (133) that penetrates the vision lower part (132) in the vertical direction and through which the vision camera module (220) is inserted.

[0080] The outer end of the above-mentioned vision upper part (131) and the lower end of the above-mentioned outer surface (145) form an installation gap (a).

[0081] The above installation spacing (a) is formed to be longer than the thickness (t) of the above installation space (148).

[0082] The above case catch portion (150) is positioned on the radial outer side of the mount hole (113).

[0083] In this embodiment, the case catch portion (150) includes a first case catch portion (151), a second case catch portion (152), a third case catch portion (not shown), and a fourth case catch portion (154).

[0084] When viewed from a top view, the first case catch portion (151), the second case catch portion (152), the third case catch portion (not shown), and the fourth case catch portion (154) each form an angle of 90 degrees. In this embodiment, the first case catch portion (151) is positioned facing forward, the second case catch portion (152) is positioned facing left, the third case catch portion (not shown) is positioned facing rear, and the fourth case catch portion (154) is positioned facing right.

[0085] Since the configurations of the first case catch part (151), the second case catch part (152), the third case catch part (not shown), and the fourth case catch part (154) are identical, they are collectively referred to as the case catch part (150).

[0086] The above case catch portion (150) includes a catch body portion (155) that protrudes upward from the mount upper portion (111) of the mount case (110), and a catch hook portion (156) formed to be bent away from the mount hole (113) from the catch body portion (155).

[0087] The case catch portion (150) is inserted into the bottom surface of the above frame (50), and a frame hole (not shown) is formed to form mutual catches in the up and down direction with the catch hook portion (156).

[0088] The above-mentioned hook portion (156) includes a hook-catching surface (156b) that forms a mutual catch with the inner surface of the frame (50), and a catch-sloping surface (156a) formed to be inclined upward toward the mount hole from the outer end of the hook-catching surface (156b).

[0089] The above-mentioned inclined surface (156a) prevents interference when inserted into the frame hole.

[0090] The above-mentioned locking body part (155) is elastically deformed toward the mount hole side, thereby minimizing interference or friction between the above-mentioned locking inclined surface (156a) and the frame hole.

[0091] The ease of assembly with the frame (50) can be improved through the first case catch portion (151), the second case catch portion (152), the third case catch portion (not shown), and the fourth case catch portion (154).

[0092] The outer diameter of the thermal imaging body part (144) is formed to be smaller than the inner diameter of the upper case opening (123), thereby allowing it to easily pass through the upper case opening (123).

[0093] The outer diameter of the lower case part (130) is formed to be larger than the lower outer diameter of the thermal imaging body part (144) and smaller than the inner diameter of the upper case opening (123).

[0094] The above thermal imaging camera (300) includes a first thermal imaging camera (301) and a second thermal imaging camera (302).

[0095] The first thermal imaging camera (301) and the second thermal imaging camera (302) are positioned in opposite directions. Specifically, either the first thermal imaging camera (301) or the second thermal imaging camera (302) is positioned to face one side of the passageway (13), and the other of the first thermal imaging camera (301) or the second thermal imaging camera (302) is positioned to face the other side of the passageway (13), thereby enabling the capture of thermal imaging data for six parking spaces.

[0096] The first thermal imaging camera (301) and the second thermal imaging camera (302) are installed to penetrate the thermal imaging body part (144). The focal direction of the first thermal imaging camera (301) and the second thermal imaging camera (302) is arranged to be orthogonal to the outer surface (145) of the thermal imaging body part (144).

[0097] Since the configuration of the first thermal imaging camera (301) and the second thermal imaging camera (302) is identical, they are collectively referred to as the thermal imaging camera (300).

[0098] The thermal imaging camera (300) includes a thermal imaging case (330) and a thermal imaging sensor (310) disposed inside the thermal imaging case (330).

[0099] The above thermal imaging case (330) is installed by penetrating the above thermal imaging body part (144). To this end, a thermal imaging body hole (146) is further formed that penetrates the above thermal imaging body part (144) to the inside and outside.

[0100] The thermal imaging body hole (146) includes a first thermal imaging body hole (146a) where the first thermal imaging camera (301) is installed, and a second thermal imaging body hole (146b) where the second thermal imaging camera (302) is installed.

[0101] The thermal imaging case (330) includes a thermal imaging penetration part (332) positioned to penetrate the thermal imaging body hole (146), and a thermal imaging support part (334) formed to extend outward from the thermal imaging penetration part (332) and supported on the inner surface (145a) of the thermal imaging body part (144).

[0102] The thermal image penetration part (332) is formed in a cylindrical shape, and the thermal image support part (334) is formed in a disc shape.

[0103] A connector (not shown) for electrical connection with a thermal imaging sensor (310) may be placed on the thermal imaging support (334).

[0104] A fastening member may be installed on the thermal imaging support member (334) to fix it to the thermal imaging body member (144). In this embodiment, a support catch member (160) is further included, which is disposed on the inner surface (145a) of the thermal imaging body member (144) and forms a mutual catch with the thermal imaging support member (334).

[0105] At least two support hooks (160) are arranged for one thermal imaging case (330).

[0106] The above support catch portion (160) is similar in shape to the above case catch portion (150).

[0107] The above support catch (160) includes a first support catch (not shown), a second support catch (162), a third support catch (163), and a fourth support catch (164), and the first support catch (not shown), the second support catch (162), the third support catch (163), and the fourth support catch (164) are spaced apart at 90-degree intervals along the circumferential direction of the thermal image support (334).

[0108] The above support catch portion (160) includes a support body portion (165) that protrudes inwardly at an orthogonal angle from the inner surface (145a) of the thermal imaging body portion (144), and a support hook portion (166) that protrudes from the support body portion (165) toward the thermal imaging support portion (334) and forms a mutual catch with the thermal imaging support portion (334).

[0109] The shape of the support body part (165) and the support hook part (166) is the same as the shape of the catch body part (155) and the catch hook part (156).

[0110] The hook-catching surface of the support hook portion (166) forms a mutual catch with the rear end of the thermal image support portion (334).

[0111] The spacing between the first support catch (not shown), the second support catch (162), the third support catch (163), and the fourth support catch (164) is formed to be slightly smaller than the outer diameter of the thermal image support (334).

[0112] When the thermal image support member (334) is assembled, it enters between the first support catch member (not shown), the second support catch member (162), the third support catch member (163), and the fourth support catch member (164), elastically deforming the plurality of support catch members outward, and when it comes into close contact with the thermal image body member (144), the support catch member (160) forms a mutual catch with the thermal image support member (334) in the opposite direction of entry.

[0113] This assembly structure makes it easy to assemble and install the thermal imaging camera (300).

[0114] In this embodiment, the thermal imaging sensor (310) forms a field of view of 110 degrees.

[0115] The thermal image penetration part (332) includes a penetration part exposure surface (332a) positioned toward the parking surface, and a penetration part outer surface (332b) that penetrates the thermal image body hole (146) and is surrounded by a light source module (400).

[0116] The above-mentioned through-hole exposed surface (332a) is positioned at an angle of 34.5 degrees relative to the mount upper part (111) or the non-lower part (132), and this is defined as the sensor inclination angle (S). The above-mentioned through-hole exposed surface (332a) is positioned parallel to the outer surface (145). The outer surface is also positioned at an angle of 34.5 degrees relative to the mount upper part (111) or the non-lower part (132) to form the sensor inclination angle (S).

[0117] Through the sensor tilt angle (S) and field of view, one thermal imaging sensor (310) can simultaneously detect multiple parking spaces.

[0118] The above-mentioned through-hole exposed surface (332a) is positioned to protrude outwardly from the outer surface of the light source module (400), thereby minimizing the limitation of the viewing angle.

[0119] The light source module (400) is formed of a material that can transmit light.

[0120] The light source module (400) comprises a light source body (410) formed of a material capable of transmitting light and surrounding the inner case portion (140), a light-emitting element (420) that projects at least two types of light sources onto the light source body (410), an inner reflective coating (430) that is coated on the inner surface of the light source body (410) to reflect light, and a camera hole (440) formed to penetrate the light source body (410) and assembled so that the thermal imaging camera (300) penetrates it.

[0121] The light source body (410) is formed in a truncated cone shape that surrounds the inner case part (140). The light source body (410) is made of a synthetic resin that is translucent or transparent and capable of transmitting light.

[0122] The light source body (410) includes an outer surface (415) forming a truncated cone-shaped outer surface, and an inner surface (415a) positioned opposite to the outer surface (415) and facing inward.

[0123] The inner reflective coating (430) is formed on the inner surface (415a). The inner reflective coating (430) can reflect light projected from the light-emitting element (420) to the outer surface (415).

[0124] The light projected from the light-emitting element (420) can be prevented from being projected into the light source body (410) through the inner reflection coating (430), thereby improving the illumination.

[0125] The light-emitting element (420) above uses an LED element that selectively emits red and blue light.

[0126] If all of the multiple parking spaces are the above-mentioned impossible parking spaces (11), red light is emitted, and if at least one of the multiple parking spaces is the possible parking space (12), blue light is emitted.

[0127] In this embodiment, the light-emitting element (420) is positioned between the outer surface (415) and the inner reflection coating (430) when viewed from the top view, and the emitted light source is incident on the upper surface of the light source body (410).

[0128] In this embodiment, the light-emitting element (420) is placed in the upper case (120). Unlike this embodiment, the light-emitting element (420) may be placed in the lower case portion (130). When the light-emitting element (420) is placed in the lower case portion (130), the emitted light is reflected from the inner reflective coating (430) and passes through the outer surface (415), so the amount of horizontal transmission can be increased.

[0129] When the light-emitting element (420) is placed in the upper case (120), the emitted light is projected directly onto the outer surface (415), so the amount of downward transmission can be increased.

[0130] When viewed from a top view, the plurality of light-emitting elements (420) are arranged at equal angles along the circumferential direction of the light source body (410). In this embodiment, 12 light-emitting elements (420) are arranged at 36-degree intervals.

[0131] The camera hole (440) includes a first camera hole (441) formed to penetrate the light source body (410) and into which the first thermal imaging camera (301) is inserted, and a second camera hole (442) formed to penetrate the light source body (410) and into which the second thermal imaging camera (302) is inserted.

[0132] The first camera hole (441) and the second camera hole (442) are arranged perpendicular to the inner surface (415a). A thermal imaging penetration part (332) is inserted through the first camera hole (441) and the second camera hole (442).

[0133] The above-mentioned through-hole exposed surface (332a) is positioned to protrude outward from the outer surface (415).

[0134] The light source body (410) can be divided into multiple zones.

[0135] The light source body (410) includes a first light source body part (411) in which a first camera hole (441) is arranged, and a second light source body part (412) in which a second camera hole (442) is arranged.

[0136] The first light source body part (411) and the second light source body part (412) are formed integrally.

[0137] Depending on whether the vehicle is parked, the first light source body part (411) and the second light source body part (412) emit light in different colors. In this case, color mixing may occur at the boundary between the first light source body part (411) and the second light source body part (412).

[0138] To prevent this, a partition reflective coating (450) is further disposed to partition the first light source body part (411) and the second light source body part (412).

[0139] The above-mentioned partition reflective coating (450) may be made of the same material as the above-mentioned inner reflective coating (430). Through the above-mentioned partition reflective coating (450), when the first light source body part (411) and the second light source body part (412) emit light of different colors, color mixing can be prevented and the driver's visibility can be improved.

[0140] Based on the above-mentioned section reflective coating (450), the first light source body part (411) is placed on one side and the second light source body part (412) is placed on the other side.

[0141] Unlike the present embodiment, the entire light source body (410) can be illuminated in a single color without a partition reflective coating (450). For example, if all of the multiple parking spaces are the impossible parking spaces (11), it emits red light, and if at least one of the multiple parking spaces is the possible parking space (12), it emits blue light.

[0142] In this embodiment, a speaker (350) is further disposed in the lower case portion (130).

[0143] The operation method of the fire detection type parking guidance camera according to the present embodiment is to transmit a fire warning through a built-in speaker (350) when the temperature value detected by either the first thermal imaging camera (301) or the second thermal imaging camera (302) is greater than or equal to a reference value.

[0144] In addition, if the temperature value detected by either the first thermal imaging camera (301) or the second thermal imaging camera (302) is greater than or equal to a reference value, a fire signal is transmitted to a pre-registered server (not shown).

[0145] At this time, the location of the fire is transmitted to the server by transmitting the ID of the fire-detecting parking guidance camera that detected the fire.

[0146] In particular, upon detection of the above fire signal, the direction of the thermal imaging camera that detected the fire from the fire-detecting parking guidance camera is also transmitted, along with the ID of the CCTV camera in the corresponding area, thereby improving the manager's fire response speed.

[0147] In particular, it can provide a fire indicator on the CCTV screen of the relevant area by linking with the apartment management system.

[0148] In addition, if the temperature value detected by either the first thermal imaging camera (301) or the second thermal imaging camera (302) is greater than or equal to a reference value, a fire extinguishing device such as a sprinkler can be controlled to operate automatically.

[0149] Generally, fire extinguishing devices such as sprinklers remain in a non-operational state until they reach a specific temperature required for activation, so there may be a significant delay in initial fire suppression after the fire occurs.

[0150] The operation method of the fire detection type parking guidance camera according to the present embodiment is characterized by detecting a fire through a first thermal imaging camera (301) or a second thermal imaging camera (302) installed in different directions, making the fire known to a person located in the parking lot through a speaker (350) on the corresponding parking space, and transmitting the location where the fire occurred and the ID of the adjacent CCTV so that an administrator can manually operate the fire extinguishing device even before the sprinkler is activated.

[0151] Although specific embodiments have been described in the detailed description of the present invention, it is understood that various modifications are possible within the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
