Description

[Technical Field]

[0001] The present invention relates to observatory telescopes. [Background technology]

[0002] Generally, telescopes are installed on observation decks at tourist attractions, and are fixed on a vertically upright stand, allowing the user to zoom in and observe the area they are looking at by moving the telescope left and right or up and down within a certain range.

[0003] At this time, the user places his / her eye close to the eyepiece of the telescope to view the magnified image through the lens. However, even when viewing a magnified image through a conventional telescope, there is a limit to how far the magnification of the image is determined depending on the distance. In particular, even when viewing a specific area through the telescope, unless the user has background knowledge or related information about the area, it is merely a tool for simply viewing the surrounding area for a short time, as it is merely a tool for visual enjoyment.

[0004] For this reason, only a small number of people observe the surrounding areas through a telescope, as most people are unwilling to pay to view the surrounding areas through a telescope for the visual pleasure of it all.

[0005] Therefore, despite the large number of people gathered around the observation deck, the telescopes installed in the area were left in an unsightly and abandoned state. [Prior art documents] [Patent documents]

[0024] As shown in Figures 1 to 9, the observatory telescope with PTZ (Pan Tilt Zoom) function according to an embodiment of the present invention comprises a photographing unit 30 built into a housing 40, a support 110 for supporting the housing 40 and connecting it so that the housing 40 can move up and down, and a control unit 50 formed inside the housing 40 that performs overall control of the photographing unit 30 and the observatory telescope.

[0025] Specifically, the observatory telescope with PTZ function according to an embodiment of the present invention includes a housing 40 supported at a predetermined distance from the ground by a support 110, a photographing unit 30 formed inside the housing 40 and having a zoom function, a position conversion unit 20 connected to the photographing unit 30 for pan and tilt control, a touch-type display 420 formed on the housing 40 but on the side opposite the photographing direction of the photographing unit to allow user input, and a control unit 50 that controls either the photographing unit 30 or the position conversion unit 20 by receiving user input through the touch-type display 420 to control the zoom state, pan control, or tilt control.

[0026] The position conversion unit 20 according to an embodiment of the present invention may include a panning module 210 including a first step motor 212 for panning the photographing unit 30 left and right based on a control signal applied from the control unit 50 in response to a user input, and a tilting module 240 including a second step motor 242 for tilting the photographing unit 30 up and down based on a control signal applied from the control unit 50 in response to a user input.

[0027] Meanwhile, the observatory telescope according to an embodiment of the present invention may include a mounting groove 122 into which the panning module 210 is inserted and which supports the rotation of the panning module 210, a first support bracket 220 which is mounted on the upper end of the panning module 210 and rotates with the panning module 210, and which includes a first horizontal fixing base 222 and first vertical fixing bases 224 formed on both ends of the first horizontal fixing base 222, and a second support bracket 230 which is connected to the first vertical fixing base 224 at both ends so that the imaging unit 30 can be tilted and to which the tilting module 240 is connected.

[0028] The detailed configuration of the observatory telescope with PTZ function having the above-mentioned configuration will be described as follows.

[0029] First, the photographing unit 30 of the observatory telescope is supported by a support base 10 so as to be positioned at a certain height from the ground, and the support base 10 is connected to a support column 110 that supports the photographing unit 30 so as to be positioned at a certain height from the ground.

[0030] The support 110 may be of a fixed type, in which the installation position is fixed, or of a liftable type, in which the height can be changed by a control signal from the control unit 50 .

[0031] When the support 110 is of the lifting type, the support 110 is composed of a fixed base 111 that is fixed to the ground, a lifting base 112 that extends to the fixed base 111 but is configured to rise and fall based on the fixed base 111, and a lifting section 113 that provides the lifting force of the lifting base 112 to perform the lifting action.

[0032] At this time, the lifting unit 113 may be configured by a rack and pinion system, a hydraulic system, a pneumatic cylinder system, or the like, and any system that can provide a lifting force to the lifting platform may be adopted.

[0033] In addition, a flat surface is formed on the upper end of the support 110 to form a support 120 for supporting the position conversion unit 20 so that the position conversion unit 20 can be easily attached.

[0034] The receiving base 120 is also provided with a mounting groove 122 formed at a certain depth, into which a part of the lower end of the position changer 20 is mounted to support the rotation of the position changer 20 .

[0035] In addition, the receiving base 120 is formed with a first through-hole 124 that is configured to penetrate the center of the mounting groove 122 with a certain size and through which electric wires can pass so as to be electrically connected to the control unit 50 and receive power.

[0036] The cradle 120 is also provided with a stopper 126 that supports the position conversion unit 20 so as to restrict the rotation angle of the position conversion unit 20 mechanically.

[0037] The stopper 126 is configured to stand at a certain height on the receiving base 120 and prevents the rotation angle of the position conversion unit 20 from exceeding, for example, a range of 120° to 180°. In this case, the stopper 126 is configured on both sides of the mounting groove 122 at a range of 60° to 90°.

[0038] The receiving base 120 is formed with at least one first fastening hole 128 to which fastening means, such as a bolt and nut or a fastening bolt, is fastened to support and fix the housing 40 .

[0039] Also, the receiving base 120 is formed with at least one second fastening hole 129 for fastening the first step motor formed in the position conversion unit 20 by a fastening means.

[0040] The position conversion unit 20 is disposed on the upper end of the support base 10 and pans or tilts the photographing unit 30 to maximize the viewing efficiency.

[0041] The position conversion unit 20 includes a panning module 210 , a first support bracket 220 , a second support bracket 230 and a tilting module 240 .

[0042] The pan module 210 rotates the photographing unit 30 left and right at a certain angle.

[0043] The pan module 210 includes a first step motor 212 that generates a forward or reverse rotation force according to a control signal provided from the control unit 50. In this case, the first step motor 212 is configured on one side of the receiving base 120, and the first step motor 212 is fixed to the receiving base 120 by fastening means to the second fastening holes 129.

[0044] The first step motor 212 includes a first driving gear 214 fixed to an extension shaft and rotated by a forward or reverse rotation force generated by the first step motor 212 .

[0045] The bread module 210 also includes a first driven gear 216 that is disposed on the upper end of the receiving plate and receives a forward or reverse rotation force from the first driving gear 214 to rotate at a predetermined angle.

[0046] In this case, an idle gear 215 is provided between the first driving gear 214 and the first driven gear 216 to support the first driven gear 216 so that it can rotate at a low speed according to the gear ratio, and to protect the first driven gear 216 by preventing the rotational force of the first step motor 212 from being directly transmitted to the first driven gear 216.

[0047] That is, the idle gear 215 is arranged between the first driving gear 214 and the first driven gear 216, and buffers the rotational force provided through the first driving gear 214 from being directly transmitted to the first driven gear 216, thereby protecting the first driven gear 216. Of course, the present invention is not limited to this, and the idle gear 215 may be omitted, and the first driven gear 216 may be configured to directly mesh with the first driving gear 214.

[0048] The first driven gear 216 is also provided with a mounting boss 218 that is inserted into the mounting groove 122 of the holder 120 to support forward or reverse rotation of the first driven gear 216. In this case, the mounting boss 218 is formed to protrude at a certain height from the lower end of the first driven gear 216.

[0049] In addition, a second through-hole 219 is formed at the center of the first driven gear 216 to penetrate the first driven gear 216 by a certain size so that an electrical connection line or an electric wire for supplying power provided through the control unit 50 can pass through. In this case, the second through-hole 219 is configured to pass through the first driven gear 216 and the mounting boss 218.

[0050] In addition, the first driven gear 216 is configured to have at least one stop pin 216a protruding from the outer periphery by a certain length, and the rotation angle is adjusted and controlled by the stopper 126 configured on the receiving base 120.

[0051] The position conversion unit 20 may include a first support bracket 220 attached to the upper end of the pan module 210 .

[0052] The first support bracket 220 is attached to the upper end of the pan module 210 and rotates with the rotation of the pan module 210 while supporting the second support bracket 230 .

[0053] The first support bracket 220 is formed in a flat shape and includes a first horizontal fixing base 222 that is mounted on the upper end of the first driven gear 216 .

[0054] In addition, the first horizontal fixing base 222 is formed with a third through-hole 2222 configured to penetrate through the center so that an electrical connection line provided through the control unit 50 or an electric wire for supplying power can pass through.

[0055] In addition, the first horizontal fixing base 222 is provided with at least one third fastening hole 2224 that is firmly fixed to the first driven gear 216 by a fastening means, thereby supporting the first horizontal fixing base 222 so as to rotate together with the first driven gear 216.

[0056] In addition, first vertical fixing blocks 224 are configured to stand at a certain height on both ends of the first horizontal fixing block 222 so that the second support bracket 230 and the tilting module 240 can be stably mounted thereon.

[0057] The first vertical fixing bases 224 are configured in plurality so as to stand at a certain height on each end of the first horizontal fixing base 222, and since the second support bracket 230 is positioned at a certain height, the second support bracket 230 can rotate, i.e., tilt, smoothly within a certain range in the up and down directions.

[0058] In addition, the first vertical fixing blocks 224 are formed with insertion holes 2242 into which both ends of the second support bracket 230 are inserted, respectively, to allow the second support bracket 230 to rotate smoothly.

[0059] The insertion holes 2242 are formed in each of the plurality of first vertical fixing plates 224, and both ends of the second support bracket 230 are inserted therein, thereby allowing the second support bracket 230 to rotate a certain angle in the upward and downward directions around the insertion holes 2242. In this case, the insertion holes 2242 may be formed so as to penetrate the first vertical fixing plates 224 or to have a certain depth, and any structure or shape may be selected as long as it allows the second support bracket 230 to rotate smoothly in the upward and downward directions.

[0060] In addition, at least one fourth fastening hole 2244 is formed in any one of the plurality of first vertical fixing blocks 224 so that the second step motor of the tilting module 240 is fixed by a fastening means. In this case, the fourth fastening hole 2244 is formed below the insertion hole 2242.

[0061] Furthermore, a distance maintaining stand 226 is provided between the first vertical fixing stands 224 to support and maintain the distance between the first vertical fixing stands 224. In this case, the distance maintaining stand 226 is provided on the upper ends of the first vertical fixing stands 224. Of course, this is not limited thereto, and at least one distance maintaining stand 226 may be provided at various positions depending on the configuration of the second support bracket 230 and the tilting module 240, and the distance maintaining stand 226 may be removed in some cases.

[0062] Meanwhile, the first support bracket 220 is configured by assembling the first horizontal fixing base 222, the first vertical fixing base 224, and the gap maintaining base 226, thereby enabling smooth assembly of the second support bracket 230 and the tilting module 240.

[0063] The second support bracket 230 is configured to be supported by the first support bracket 220 and rotates by a predetermined angle in the upward and downward directions by the tilting module 240 .

[0064] The second support bracket 230 is formed flat, and has a second horizontal fixing table 232 at its upper end for supporting the imaging unit 30 so that it is fixed thereto.

[0065] The second horizontal fixing base 232 is formed with a fourth through-hole 2322 configured to penetrate with a certain size so that an electrical connection line provided through the control unit 50 or an electric wire for supplying power can pass through.

[0066] In addition, the second horizontal fixing table 232 is provided with a plurality of second vertical fixing tables 234 at both ends thereof, each of which is configured to stand at a fixed height.

[0067] The plurality of second vertical fixing bases 234 are configured to protrude at a certain length and have insertion shafts 2342 formed thereon, which are inserted into insertion holes 2242 formed in the first vertical fixing base 224, thereby supporting the base so that it can rotate at a certain angle in the upward and downward directions based on the insertion holes 2242.

[0068] The insertion shafts 2342 are formed to protrude by a certain length from each of the plurality of second vertical fixing blocks 234, and are inserted into the insertion holes 2242 of the first vertical fixing blocks 224, thereby allowing the second support bracket 230 to smoothly rotate a certain angle in the upward and downward directions relative to the first support bracket 220. In this case, the insertion shafts 2342 may be provided with bearings or bushings that support the second support bracket 230 to smoothly rotate, or the insertion holes 2242 may be provided with stop rings or the like to prevent the insertion shafts 2342 from accidentally coming off.

[0069] In addition, at least one fifth fastening hole 2344 is formed in any one of the plurality of second vertical fixing plates 234 to support the second driven gear of the tilting module 240 so that it is fixed by a fastening means. In this case, the fifth fastening hole 2344 is formed at a position where the tilting module 240 is configured, i.e., in a second vertical fixing plate 234 adjacent to the first vertical fixing plate 224 in which the fourth fastening hole 2244 is formed among the plurality of first vertical fixing plates 224.

[0070] The tilting module 240 is disposed on one side of the second support bracket 230 and rotates the second support bracket 230 upward or downward by a predetermined angle in response to a control signal from the control unit 50 .

[0071] The tilting module 240 may include a second step motor 242 that generates a forward or reverse rotation force according to a control signal from the control unit 50. In this case, the second step motor 242 is fixed to the first vertical fixing base 224, in which the fourth fixing hole 2244 is formed, among the plurality of first vertical fixing bases 224, by a fixing means.

[0072] In addition, the second step motor 242 may have a second driving gear 244 fixed to the extension shaft and rotated forward or backward by the forward or backward rotation force generated by the second step motor 242. In this case, the second driving gear 244 is disposed between the first and second vertical fixing plates 224 and 234.

[0073] The tilting module 240 may also include a second driven gear 246 that is fixed to the second vertical fixing base 234, in which the fifth fixing hole 2344 is formed, by a fastening means among the plurality of second vertical fixing bases 234. In this case, the second driven gear 246 is configured between the first and second vertical fixing bases 224 and 234, but is configured to mesh with the second driving gear 244, so that the second support bracket 230 can rotate up or down by a certain angle in response to the forward or reverse rotation of the second driving gear 244.

[0074] The photographing unit 30 is configured to be mounted on the second support bracket 230 and photographs the view while moving left and right or up and down by the action of the pan module 210 or the tilting module 240 of the position conversion unit 20.

[0075] The photographing unit 30 includes a camera 310 , a lens 320 , an adapter 330 and a fixing bracket 340 .

[0076] The camera 310 can capture a view and acquire an image in response to a control signal from the control unit 50. The acquired image can be input to the control unit 50 and displayed on the display 430.

[0077] It is more preferable that the camera 310 according to the embodiment of the present invention is an industrial camera that can easily obtain a clear image and has a digital resolution that can be easily controlled by the control unit 50 .

[0078] The lens 320 is configured at one end of the camera 310 and has a zoom-in / zoom-out function, making it easy to capture an image of a distant view. In this case, the lens 320 is preferably a digital lens that can be controlled to zoom in / out according to a control signal from the control unit 50. For example, the lens 320 is a lens for a DSLR.

[0079] The adapter 330 is disposed between the camera 310 and the lens 320 and supports the camera 310 and the lens 320 so that they can be easily attached to each other.

[0080] The fixing bracket 340 supports the photographing unit 30 so that it is stably fixed to the second support bracket 230 by a fastening means. For example, the fixing bracket 340 is formed on one side of the lens 320 and is fixed to the second horizontal fixing base 232 of the second support bracket 230 by a fastening means.

[0081] The housing 40 is configured on the support base 10 and functions to protect the position conversion unit 20 and the photographing unit 30 by preventing them from being exposed to the outside, and also maximizes viewing efficiency by allowing a user to easily check snapshots taken through the photographing unit 30 with the naked eye when outside.

[0082] The housing 40 may include a lid 410, a display 420, a protective window 430, and the like.

[0083] The cover 410 has the position change unit 20 and the imaging unit 30 located inside, and is closed at the top, bottom, left, and right to prevent the position change unit 20 and the imaging unit 30 from being exposed to the outside, and both ends are open. In this case, the bottom end of the cover 410 is fixed by being fastened to the first fastening hole 128 of the support plate 120 by a fastening means.

[0084] The display 420 is disposed at one end of the cover 410 and displays the image captured by the camera 30 in real time, thereby providing the effect of viewing the surrounding scenery. In this case, the display 420 is an LED, OLED, or plasma display capable of displaying an image. Preferably, the display 420 is a touch screen that allows the user to simultaneously adjust the direction of the viewing position or zoom in / out while looking at the screen.

[0085] That is, the display 420 is used as an input interface for controlling the panning and tilting of the photographing unit 30 through the position conversion unit 20 connected to the photographing unit 30 .

[0086] The display 420 can also be used as an input interface for zooming in and out of the lens 320 of the imaging unit 30 .

[0087] In the embodiment of the present invention, the input interface allows touch operations on the display 420 in the up, down, left, and right directions, and touch operations to shorten or lengthen the distance between two specific points.

[0088] Such user input through touch operation is input to the control unit 50, and the control unit 50 can control the position conversion unit 20 or the lens 320 according to the user input.

[0089] The protective window 430 is disposed at the other end of the cover 410, i.e., in the direction corresponding to the display 420, to protect the photographing unit 30 and also to support smooth photographing of the scenery through the photographing unit 30. In this case, the protective window 430 is formed of transparent tempered glass.

[0090] Meanwhile, the display 420 and the protective window 430 are configured to be sealed against the lid 410, thereby preventing the penetration of foreign matter into the position conversion unit 20 and the photographing unit 30 configured inside the housing 40, thereby protecting the position conversion unit 20 and the photographing unit 30 and preventing malfunctions caused by foreign matter.

[0091] The control unit 50 transmits a control signal according to the user's direction adjustment or zoom-in / out adjustment to the position conversion unit 20 or the photographing unit 30 through the display 420 to acquire the image desired by the user, and controls the acquired image to be displayed on the display 420.

[0092] In addition, when the support column 110 of the support table 10 is configured as a liftable column, the control unit 50 controls the column 110 to be liftable according to the user's physical condition, thereby providing convenience for use.

[0093] In the case of an observation deck camera with a PTZ function as described above, it was explained as an example that the stopper 126 is used to support the position conversion unit 20 so that the rotation angle can be mechanically limited. However, as shown in FIG. 10, not only can the rotation angle of the position conversion unit 20 be limited using the first sensor 500, but the tilting angle of the tilting module 240 can also be limited using the second sensor 502.

[0094] That is, the first sensor 500 is connected to the pan module 210 and senses the panning angle (rotation angle) when the photographing unit 30 is panned left and right, and the second sensor 502 is connected to the tilting module 240 and senses the tilting angle when the photographing unit 30 is tilted up and down. The sensed panning angle and tilting angle are provided to the control unit 50.

[0095] Accordingly, the control unit 50 can control the driving of the first and second step motors 212 and 242 based on the panning angle and tilting angle. That is, the control unit 50 can control the first and second step motors 212 and 242 so that the photographing unit 30 is not panned or tilted beyond a certain angle.

[0096] The above description is merely one example for carrying out the present invention, and the present invention is not limited to the above example. Those skilled in the art will understand that various modifications can be made without departing from the spirit of the present invention. [Explanation of symbols]
