Description

[Technical field]

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

[0002] Generally, telescopes are installed at the observation decks of 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 image magnified through the lens. However, when viewing a magnified image through a telescope, there is a limit because the magnification of the image is determined according to the distance. In particular, 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 visual enjoyment and only allows the user to view the surrounding area for a short time.

[0004] For this reason, only a small number of people view 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 gathering 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 an imaging unit 30 built into a housing 40, a support 110 for supporting the housing 40 and connected to the housing 40 so that the housing 40 can move up and down, and a control unit 50 formed inside the housing 40 for performing overall control of the imaging 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 position spaced a predetermined distance from the ground by a support 110, an imaging unit 30 formed inside the housing 40 and having a zoom function, a position conversion unit 20 connected to the imaging unit 30 for pan and tilt control, a touch-type display 420 formed on the housing 40 but on the side opposite to the direction in which the imaging unit takes images, which allows user input, and a control unit 50 that controls one of the imaging unit 30 and the position conversion unit 20 to control the zoom state, pan control, or tilt control by inputting user input through the touch-type display 420.

[0026] The position conversion unit 20 according to an embodiment of the present invention may include a pan 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 according 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 according 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 pan module 210 is inserted to support the rotation of the pan module 210, a first support bracket 220 which is mounted on the upper end of the pan module 210 and rotates with the pan module 210, and which includes a first horizontal fixing base 222 and a first vertical fixing base 224 formed on both ends of the first horizontal fixing base 222, and a second support bracket 230 to which a tilting module 240 is connected, the both ends of which are connected to the first vertical fixing base 224, respectively, and which is mounted so that the imaging unit 30 can be tilted.

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

[0029] First, the imaging unit 30 of the observation deck 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 which supports the imaging 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 lifting type, in which the height can be changed according to 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 a lifting force from the lifting base 112 to perform the lifting action.

[0032] At this time, the lifting unit 113 may be configured in a rack and pinion system, hydraulic or 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 has a mounting groove 122 formed at a certain depth, into which a part of the lower end of the position conversion unit 20 is mounted to support the rotation of the position conversion unit 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 by 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] Further, the receiving base 120 is 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 so that the rotation angle of the position conversion unit 20 cannot exceed, for example, a range of 120° to 180°. In this case, the stopper 126 is configured on both sides of the mounting groove 122 in the range of 60° to 90°.

[0038] In addition, the receiving base 120 is formed with at least one first fastening hole 128 to which a fastening means, for example, a bolt and a 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 stand 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 image capturing unit 30 to the left or right at a fixed 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 fastened to the second fastening hole 129.

[0044] In addition, 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] In addition, the bread module 210 includes a first driven gear 216 that is disposed on the upper end of the receiving platform and receives a forward or reverse rotation force from the first driving gear 214 to rotate at a certain 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 disposed 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 directly engaged with the first driving gear 214.

[0048] In addition, the first driven gear 216 is provided with a mounting boss 218 that is inserted into the mounting groove 122 of the receiving stand 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 the second through hole 219. 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 protrude from the outer periphery by a certain length, and at least one stop pin 216a is configured so that the rotation angle is adjusted and controlled by the stopper 126 configured on the receiving base 120.

[0051] The position converter 20 may include a first support bracket 220 mounted on 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 has a first horizontal fixing plate 222 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 or an electric wire for supplying power provided through the control unit 50 can pass through.

[0055] In addition, the first horizontal fixing base 222 is provided with at least one third fastening hole 2224 that supports the first horizontal fixing base 222 to rotate together with the first driven gear 216 by maintaining a securely fixed state to the first driven gear 216 by a fastening means.

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

[0057] The first vertical fixing base 224 is configured in plurality so as to stand at a fixed height on each end of the first horizontal fixing base 222, and the second support bracket 230 is positioned at a fixed height, so that the second support bracket 230 can be smoothly rotated, i.e., tilted, within a fixed range in the upward and downward directions.

[0058] In addition, the first vertical fixing blocks 224 are formed with insertion holes 2242 into which both ends of the second supporting bracket 230 are inserted so that the second supporting bracket 230 can rotate smoothly.

[0059] The insertion holes 2242 are formed in each of the plurality of first vertical fixing bases 224, and both ends of the second support bracket 230 are inserted into the insertion holes 2242, so that the second support bracket 230 can rotate a certain angle in the upward and downward directions around the insertion holes 2242. In this case, the insertion holes 2242 are formed to penetrate the first vertical support bases 224 or to a certain depth, and any structure or shape that allows the second support bracket 230 to rotate smoothly in the upward and downward directions can be selected.

[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] In addition, a gap maintaining stand 226 is provided between the first vertical fixing stands 224 to support and maintain the gap between the first vertical fixing stands 224. In this case, the gap maintaining stand 226 is provided on the upper end of the first vertical fixing stands 224. Of course, this is not limited to this, and at least one gap 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 gap maintaining stand 226 may be removed if necessary.

[0062] Meanwhile, the first support bracket 220 includes a first horizontal fixing stand 222, a first vertical fixing stand 224, and a gap maintaining stand 226 which are assembled together, thereby allowing the second support bracket 230 and the tilting module 240 to be smoothly assembled.

[0063] The second support bracket 230 is configured to be supported by the first support bracket 220 and rotated by a certain 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 on the upper end thereof for supporting and fixing the imaging unit 30.

[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 or a wire for supplying power provided through the control unit 50 can enter and exit.

[0066] In addition, the second horizontal fixing table 232 has a plurality of second vertical fixing tables 234 arranged to stand at a certain height on both ends thereof.

[0067] The multiple second vertical fixing bases 234 are configured to protrude at a certain length, and an insertion shaft 2342 is formed that is inserted into the insertion hole 2242 formed in the first vertical fixing base 224 to support the insertion shaft 2342 so that it can rotate at a certain angle in the upward and downward directions based on the insertion hole 2242.

[0068] The insertion shaft 2342 is formed to protrude at a certain length from each of the plurality of second vertical fixing blocks 234, and is inserted into the insertion hole 2242 of the first vertical fixing block 224, thereby allowing the second support bracket 230 to smoothly rotate at a certain angle in the upward and downward directions based on the first support bracket 220. In this case, the insertion shaft 2342 may be configured with a bearing or a bushing that supports the second support bracket 230 so as to allow smooth rotation, or a stop ring may be configured in the insertion hole 2242 to prevent the insertion shaft 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 tables 234 to support the second driven gear of the tilting module 240 so as to be fixed by a fastening means. In this case, the fifth fastening hole 2344 is formed in a position where the tilting module 240 is constructed, i.e., in the second vertical fixing table 234 adjacent to the first vertical fixing table 224 in which the fourth fastening hole 2244 is formed among the plurality of first vertical fixing tables 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 certain angle according 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 table 224, in which the fourth fastening hole 2244 is formed, among the plurality of first vertical fixing tables 224, by a fastening means.

[0072] In addition, the second step motor 242 may have a second driving gear 244 fixed to an extension shaft and rotated forward or backward by a 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] In addition, the tilting module 240 may be configured with a second driven gear 246 that is fixed to the second vertical fixing table 234, in which the fifth fastening hole 2344 is formed, among the plurality of second vertical fixing tables 234, by a fastening means. In this case, the second driven gear 246 is configured between the first and second vertical fixing tables 224 and 234, but is configured to mesh with the second driving gear 244, so that the second support bracket 230 can rotate a certain angle in the upward or downward direction by receiving 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 according 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 is easy to control 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 supporting bracket 230 by a fastening means. For example, the fixing bracket 340 is configured on one side of the lens 320 and fixed to the second horizontal fixing table 232 of the second supporting bracket 230 by a fastening means.

[0081] The housing 40 is configured on the support 10 and serves to protect the position conversion unit 20 and the photographing unit 30 from exposure to the outside, and also allows a user to easily check snapshots taken through the photographing unit 30 with the naked eye from the outside, thereby maximizing viewing efficiency.

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

[0083] The position conversion unit 20 and the imaging unit 30 are located inside the cover 410, but the top, bottom, left and right are closed to prevent the position conversion 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 an effect of viewing the surrounding scenery. In this case, the display 420 is a display made of LED, OLED, or plasma 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] In addition, the display 420 can be used as an input interface for controlling the zoom-in / zoom-out of the lens 320 of the imaging unit 30 .

[0087] In an 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 a user input by a 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 a direction corresponding to the display 420, to protect the photographing unit 30 and 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 obtain the image desired by the user, and controls the obtained image to be displayed on the display 420.

[0092] In addition, when the support 110 of the support stand 10 is configured as a lifting type, the control unit 50 controls the support 110 to be lifted or lowered according to the physical condition of the user, thereby providing convenience for use.

[0093] In the case of the observation deck camera having the PTZ function as described above, it has been described 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 a first sensor 500, but the tilting angle of the tilting module 240 can also be limited using a second sensor 502.

[0094] That is, the first sensor 500 is connected to the pan module 210 to sense 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 to sense the tilting angle when the photographing unit 30 is tilted up and down. The panning angle and tilting angle sensed in this manner 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 imaging unit 30 is not panned or tilted beyond a certain angle.

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