Description

Technical Field

[0001] The present invention relates to a clamping apparatus for an antenna and a control method thereof, and more particularly to a clamping apparatus for an antenna and a control method thereof, which can efficiently arrange an antenna in a dense installation space and easily adjust the direction of the antenna. Background Art

[0002] Generally, wireless communication technologies, such as Multiple Input Multiple Output (MIMO) technology, are technologies that significantly increase data transmission capacity by using multiple antennas. It is a spatial multiplexing method in which different data is transmitted through each transmitting antenna in a transmitter and the transmitted data is distinguished by appropriate signal processing in a receiver.

[0003] Therefore, increasing the number of transmitting and receiving antennas simultaneously increases the channel capacity, allowing for more data to be transmitted. For example, increasing the number of antennas to 10 ensures approximately 10 times the channel capacity compared to a conventional single-antenna system using the same frequency band.

[0004] 4G LTE-Advanced uses up to eight antennas, but in the pre-5G phase, products with 64 or 128 antennas are currently under development. 5G is expected to use base stations with even more antennas, a technology known as Massive MIMO. While current cell operations are two-dimensional, the introduction of Massive MIMO technology enables three-dimensional beamforming, also known as Full-Dimensional MIMO (FD-MIMO).

[0005] In massive MIMO technology, as the number of antennas (ANTs) increases, the number of transmitters and filters required also increases. However, due to space constraints and rental requirements, RF components (antennas, filters, power amplifiers, transceivers, etc.) need to be made smaller and lighter to reduce costs. However, massive MIMO technology requires high output to extend coverage, but the power consumption and heat generation associated with this high output are detrimental factors in reducing weight and size.

[0006] In particular, when a multi-input multi-output antenna that combines modules of RF devices and digital devices in a stacked structure is set up within a limited space, in order to maximize the ease of installation or space utilization, the necessity of compact and miniaturized design related to the multiple layers constituting the multi-input multi-output antenna becomes prominent, and there is a strong need for free directional adjustment of the antenna device set on a support pole.

[0007] At the same time, in the past, in order to adjust the direction of the multi-input multi-output antenna set up in a confined space, workers needed to go directly to a high place to make adjustments, which increased the risk of falling and significantly reduced the stability of the work. Summary of the Invention

[0008] Technical issues

[0009] The technical problem of the present invention is to provide an antenna clamping device and a control method thereof, which can prevent workers from falling when adjusting the direction of the antenna.

[0010] Another technical problem of the present invention is to provide an antenna clamping device and a control method thereof, which can easily absorb small vibrations caused by the external setting of the antenna to prevent the occurrence of abnormal noise and easily adjust the direction.

[0011] The technical problems of the present invention are not limited to the technical problems mentioned above. Ordinary technicians in the technical field to which the present invention belongs can clearly understand other technical problems not mentioned from the following description.

[0057] An antenna clamping device according to an embodiment of the present invention is described below.

[0058] Reference Figures 1 to 5The antenna clamping device 10 according to one embodiment of the present invention may include a rotation drive unit 30, a tilt drive unit 200, and a tilt unit 100. The rotation drive unit 30 may be coupled to the front end of the arm unit 500 coupled to the support pole 1. The tilt drive unit 200 is coupled to the rotation drive unit 30 so as to be rotatable in the horizontal direction. The tilt unit 100 is coupled to the tilt drive unit 200 so as to be rotatable in the vertical direction. Here, rotation in the horizontal direction may have the same meaning as rotational rotation, and rotation in the vertical direction may have the same meaning as tilting rotation. That is, rotation in the horizontal direction and rotational rotation may mean rotation with the vertical axis as the rotation center. Furthermore, rotation in the vertical direction and tilting rotation may mean rotation with the horizontal axis as the rotation center.

[0059] Reference Figure 1 The arm unit 500 can extend a predetermined length along one side of the horizontal direction of the holding pole 1 vertically arranged in the upward and downward directions, and the rotation driving unit 30 can play the role of a medium combined with the holding pole 1.

[0060] In more detail, the arm unit 500 may include an arm body 510, a fixed bracket 520, and a detachable bracket 530. The arm body 510 may extend horizontally. At either end of the arm body 510, with the end farther from the mast 1 being one end and the end closer to the mast 1 being the other end, the fixed bracket 520 may be integrally formed with the other end of the arm body 510 and disposed on one side of the outer circumference of the mast 1. The detachable bracket 530 may be provided separately from the arm body 510 and disposed on the other side of the outer circumference of the mast 1. The detachable bracket 530 may be coupled to the fixed bracket 520 via a plurality of long fixing bolts 540 and fixing nuts 550.

[0061] The arm body 510 and the fixed bracket 520 can be welded together. To ensure sufficient rigidity to withstand the combined weight of the antenna A and the clamping device 10 attached to the front end of the tilt unit 100, a plurality of rigid ribs 560 can be welded together at the joint between the arm body 510 and the fixed bracket 520, spaced a predetermined distance apart along the edge of the arm body 510.

[0062] The antenna clamping device 10 according to an embodiment of the present invention may be installed at the front end of the arm unit 500 .

[0063] The antenna clamping device 10 can set the antenna A on the arm unit 500, and rotate or tilt it in a manner that can set the direction of the antenna A. It can be a structure that collectively refers to the above-mentioned tilting unit 100, tilting drive unit 200 and rotation drive unit 30.

[0064] Furthermore, the antenna clamping device 10 can automatically achieve tilting and rotating of the tilt unit 100 and the tilt driving unit 200 by electrically driven motors (rotation motors 251, 351 and rotation prevention motors 271, 371 described later).

[0065] The tilting unit 100 may include an antenna coupling block 110 and a pair of tilting coupling plates 120. The antenna coupling block 110 is essentially the location where the antenna A is mounted and fixed, and may be in the shape of a quadrilateral plate with flat vertical surfaces. Bolt flanges 112 are provided on both sides of the antenna coupling block 110, extending along the outer side for a predetermined length. Bolt fastening holes 113 extending in the forward and rearward directions may be provided on the bolt flanges 112, allowing the antenna A to be securely fixed to the antenna coupling block 110 using fixing bolts (or screws) (not shown). The fixing bolts are tightened through the bolt fastening holes 113. Specifically, bolt fastening holes 113 for bolting to the antenna A may be provided on both sides of the antenna coupling block 110, and the antenna A may be bolted to the front ends of the bolt flanges 112 on both sides. The pair of tilting coupling plates 120 may extend rearward from the rear of the antenna coupling block 110.

[0066] For the sake of convenience, the antenna coupling block 110 and the pair of inclined coupling plates 120 are distinguished from each other. In the tilting unit 100 , the antenna coupling block 110 and the pair of inclined coupling plates 120 may be formed as one body.

[0067] A tilt shaft engaging protrusion 111, which is inserted and engaged with a tilt shaft hole 236 provided in the tilt drive unit 200 (described later), may be provided on the inner side surface of one of the pair of tilt engaging plates 120. The tilt shaft engaging protrusion 111 may serve as the vertical rotation center of the tilt unit 100. The tilt shaft engaging protrusion 111 may be inserted into a tilt shaft engaging protrusion insertion hole 259a formed on the tilt shaft 259, which is fixed to the structure of the tilt rotation adjustment unit 250.

[0068] The tilt shaft engaging protrusion 111 can be substantially in the shape of a rod having a pentagonal or hexagonal vertical cross-section. Furthermore, the tilt shaft engaging protrusion insertion hole 259a formed in the tilt shaft 259 can be in the shape of a groove capable of retaining the tilt shaft engaging protrusion 111. When the tilt shaft 259 rotates in the tilting direction, the tilt shaft engaging protrusion 111 and the tilt shaft 259 rotate in conjunction.

[0069] Reference Figure 3The tilt drive unit 200 may include a tilt support block 210 and a rotation coupling plate 220. The tilt support block 210 may be formed with a tilt shaft hole 236 into which the tilt shaft coupling protrusion 111 of the tilt coupling plate 120 is inserted. The tilt support block 210 rotatably supports the inner side of the tilt coupling plate 120. The rotation coupling plate 220 may extend rearward from the upper side of the tilt support block 210. The rotation coupling plate 220 is rotatably coupled to the rotation drive unit 30.

[0070] The tilt support block 210 and the rotation coupling plate 220 may be formed as a single body. A space may be formed inside the tilt support block 210 to accommodate a tilt rotation adjustment unit 250, which is a structure related to tilt rotation among the rotation adjustment units 250 and 350 described later, and a tilt vibration prevention unit 270, which is one of the vibration prevention units 270 and 370 described later.

[0071] In more detail, the tilt support block 210 may include a rotating housing 231 and a rotating cover housing 232. The rotating housing 231 may be formed with the aforementioned installation space with one side open and the rotating coupling plate 220. The rotating cover housing 232 may be coupled to one side of the opening of the rotating housing 231 to shield the aforementioned installation space formed in the rotating housing 231.

[0072] The lower side of the rotation coupling plate 220 is coupled to the upper portion of the rotation drive unit 30 in surface-to-surface contact. A rotation axis coupling protrusion 211 may extend a predetermined length downward toward the rotation drive unit 30 on the lower side of the rotation coupling plate 220. A rotation axis hole 37 may be formed in the rotation drive unit 30 through which the rotation axis coupling protrusion 211 passes. The rotation axis coupling protrusion 211 may be connected to the rotation adjustment portion 350 of the rotation adjustment portions 250 and 350 described later.

[0073] The rotation drive unit 30 may include a rotation support block 31 and an arm fastening block 32. The rotation coupling plate 220 may be fastened to the rotation support block 31 so as to be rotatable in the horizontal direction. The arm fastening block 32 may extend rearward from the rear of the rotation support block 31 and be coupled to the front end of the arm unit 500.

[0074] The rotation support block 31 and the arm fastening block 32 may be formed integrally. A space may be formed inside the rotation support block 31 to accommodate a rotation adjustment portion 350 (rotation-related structure of the rotation adjustment portions 250 and 350 described later) and a rotation vibration prevention portion 370 (rotation vibration prevention portion 270 and 370 described later).

[0075] In more detail, the rotation support block 31 may include a coupling cover 331 and a coupling cover 332. The coupling cover 331 may form the aforementioned installation space with an opening at the lower side and the arm fastening block 32. The coupling cover 332 is coupled to the lower side of the opening of the coupling cover 331 to shield the aforementioned installation space formed in the coupling cover 331.

[0076] As described above, in the antenna clamping device 10 according to one embodiment of the present invention, the tilting drive unit 200 is coupled to the rotation drive unit 30 in a manner that allows it to rotate horizontally with the rotating shaft coupling protrusion 211 as the center, thereby enabling the antenna A to rotate horizontally. At the same time, the tilting unit 100 is coupled to the tilting drive unit 200 in a manner that allows it to rotate upward and downward with the tilting shaft coupling protrusion 111 as the center, thereby allowing the antenna A to rotate horizontally and upward and downward to adjust its direction.

[0077] Reference Figure 3 The antenna clamping device 10 according to an embodiment of the present invention may include rotation adjustment parts 250 and 350, respectively, which are arranged in the setting space of the tilt support block 210 of the tilt driving unit 200 in a manner that enables the tilt and rotation operations of the tilt unit 100, or are arranged in the setting space of the rotation support block 31 of the rotation driving unit 30 in a manner that enables the rotation and rotation operations of the tilt driving unit 200.

[0078] Figure 6a and Figure 6b To follow Figure 1 The cross-sectional view and cut-away stereogram taken along line AA of Figure 7a and Figure 7b To follow Figure 1 The cross-sectional view and cut-away stereogram taken along line BB are shown.

[0079] Reference Figures 3 to 7b The rotation adjustment unit 250, 350 may include a tilt adjustment unit 250, disposed within the tilt drive unit 200; and a rotation adjustment unit 350, disposed within the rotation drive unit 30. Both the rotation adjustment units 250, 350 may be automatically driven by electrically driven rotation motors 251, 351. For ease of description, the rotation motor 251 of the tilt adjustment unit 250 will be referred to as the tilt motor 251, and the rotation motor 351 of the rotation adjustment unit 350 will be referred to as the rotation motor 351.

[0080] The antenna clamping device 10 may also include vibration prevention components 270 and 370. These components may be provided on the tilt drive unit 200 and the rotation drive unit 30, respectively. These components 270 and 370 can prevent vibrations caused by external forces (or the external environment) or angle changes caused by impact. These components 270 and 370 can be automatically driven by electrically driven rotation prevention motors 271 and 371.

[0081] Hereinafter, the structures of the rotation adjusting parts 250 and 350 and the vibration preventing parts 270 and 370 will be described in more detail.

[0082] Reference Figure 4 、 Figure 6a and Figure 6b In the rotation adjustment part 250, 350, the tilt rotation adjustment part 250 may include: a tilt rotation motor 251, which is electrically driven; a tilt worm gear 252, which is rotated by the axis of the tilt rotation motor 251; a tilt worm gear 253, which is engaged with the tilt worm gear 252; and a tilt shaft 259, on which the tilt worm gear 253 is formed as a whole.

[0083] The front end of the tilt shaft 259 may be formed with a tilt shaft coupling protrusion insertion hole 259a into which the tilt shaft coupling protrusion 111 of the tilt unit 100 is inserted and coupled. The tilt shaft coupling protrusion 111 may pass through the tilt shaft hole 236 formed in the rotating housing 231 and flow into the rotating housing 231 before being inserted into the tilt shaft coupling protrusion insertion hole 259a to couple with the tilt shaft 259. The tilt shaft coupling protrusion 111 may be press-fitted into the tilt shaft coupling protrusion insertion hole 259a and rotate in conjunction with the tilt shaft 259. As described above, the tilt shaft coupling protrusion insertion hole 259a corresponds to the vertical cross-sectional shape of the tilt shaft coupling protrusion 111. When the tilt shaft 259 rotates, the tilt shaft coupling protrusion 111 rotates in conjunction with the tilt shaft 259, rotating the tilt unit 100 integrally formed with the tilt shaft coupling protrusion 111 and tilting the antenna A.

[0084] The tilt adjustment unit 250 may further include a first support bearing 280a and a second support bearing 280b that rotatably support one end and the other end of the tilt shaft 259, respectively. The first support bearing 280a and the second support bearing 280b rotatably support the tilt shaft 259 within the rotating housing 231.

[0085] The tilting and rotating adjusting part 250 can automatically rotate the tilting shaft coupling protrusion 111 connected to the tilting shaft 259 by rotating the tilting worm gear 252 and the tilting worm gear 253 along the direction of rotation drive of the tilting and rotating motor 251, thereby rotating the tilting shaft 259, thereby rotating the tilting shaft coupling protrusion 111 connected to the tilting shaft 259, thereby rotating the tilting unit 100 in the upward and downward directions.

[0086] On the other hand, refer to Figure 5 、 Figure 7a and Figure 7b The rotation regulating portion 350 in the rotation regulating portion 250, 350 may include: a rotation motor 351; a rotation worm gear 352, which is rotated by the rotation motor 351 shaft; a rotation worm gear 353, which is engaged with the rotation worm gear 352; and a rotation shaft 359, on which the rotation worm gear 353 is formed as a whole.

[0087] A rotation shaft coupling protrusion insertion hole 359a is formed at the front end of the rotation shaft 359, into which the rotation shaft coupling protrusion 211 of the tilt drive unit 200 is inserted. The rotation shaft coupling protrusion 211 can pass through the rotation shaft hole 37 formed in the coupling housing 331 of the rotation drive unit 30, flow into the coupling housing 331, and then be inserted into the rotation shaft coupling protrusion insertion hole 359a to couple with the rotation shaft 359. The rotation shaft coupling protrusion 211 can be pressed and snapped into the rotation shaft coupling protrusion insertion hole 359a, and rotate in conjunction with the rotation shaft 359.

[0088] Similar to the aforementioned tilting shaft coupling protrusion 111, the rotating shaft coupling protrusion 211 can be roughly shaped like a rod with a pentagonal or hexagonal vertical cross-section. Furthermore, the rotating shaft coupling protrusion insertion hole 359a formed in the rotating shaft 359 can be shaped like a groove capable of retaining the rotating shaft coupling protrusion 211. This allows the rotating shaft coupling protrusion 211 to rotate in conjunction with the rotating shaft 359 when the rotating shaft 359 rotates in the rotational direction.

[0089] The rotation adjustment unit 350 may further include a first support bearing 380a and a second support bearing 380b that rotatably support one end and the other end of the rotation shaft 359, respectively. The first support bearing 380a and the second support bearing 380b serve to rotatably support the rotation shaft 359 within the housing 331.

[0090] The rotation adjustment part 350 can rotate the rotating shaft 359 by rotating the rotating worm gear 352 and the rotating worm gear 353 according to the direction of the rotating drive of the rotating motor 351, so that the rotating shaft coupling protrusion 211 connected to the rotating shaft 359 can automatically rotate, thereby allowing the tilt driving unit 200 to rotate in the horizontal direction.

[0091] On the other hand, refer to Figure 4 、 Figure 6a and Figure 6bIn the structure of the vibration prevention part 270, 370, the tilted vibration prevention part 270 may include: a pair of tilted brake plates 274, combined on the outer peripheral surface of the tilted shaft 259; and a tilted rotation prevention gear 273, so that the pair of tilted brake plates 274 are close to each other or separated from each other.

[0092] Among them, one of the pair of inclined brake plates 274 can rotate in conjunction with the inclined shaft 259, and the other can prevent the rotation of the gear 273 from moving in the axial direction of the inclined shaft 259 by being inclined and rotated separately from the inclined shaft 259.

[0093] In more detail, the tilting rotation preventing gear 273 may be in a ring shape and have an internal thread formed on the inner circumference, and an external thread that is fastened to the internal thread of the tilting rotation preventing gear 273 may be formed on the outer circumference of the main body of the other one of the pair of tilting brake plates 274, so that the outer circumference of the main body is screwed to the inner circumference of the tilting rotation preventing gear 273.

[0094] Therefore, when the tilting prevention gear 273 is rotated in place by the tilting prevention motor 271 described later, the main body of the other of the pair of tilting brake plates 274 moves linearly in the axial direction and comes into close contact with or is spaced apart from the pair of tilting brake plates 274 .

[0095] Meanwhile, the tilt rotation preventing gear 273 may be electrically driven by a tilt rotation preventing motor 271 provided inside the tilt driving unit 200 .

[0096] The driving force of the tilt-rotation prevention motor 271 may be transmitted to the tilt-rotation prevention gear 273 via the tilt-vibration prevention worm gear 272 and the tilt-vibration prevention intermediate gear 276 .

[0097] If the tilt rotation prevention motor 271 rotates in one direction (hereinafter defined as the "locking direction"), the tilt vibration prevention worm gear 272 and the tilt vibration prevention intermediate gear 276 rotate in one direction, and the tilt rotation prevention gear 273 rotates in the locking direction and makes a pair of tilt brake plates 274 close to each other, thereby preventing the tilt shaft 259 from rotating at will.

[0098] On the contrary, if the tilt rotation prevention motor 271 rotates in the other direction (hereinafter defined as the "lock release direction"), the tilt vibration prevention worm gear 272 and the tilt vibration prevention intermediate gear 276 rotate in the other direction, and the tilt rotation prevention gear 273 rotates in the lock release direction, and the pair of tilt brake plates 274 that are in a close contact state are separated from each other, so that the tilt shaft 259 can be converted into a state where it can rotate (rotate).

[0099] On the other hand, refer to Figure 5 、 Figure 7a and Figure 7bIn the structure of the vibration prevention parts 270 and 370, the rotational vibration prevention part 370 may include: a pair of rotational brake plates 374, which are combined on the outer peripheral surface of the rotation shaft 359; and a rotational rotation prevention gear 373, so that the pair of rotational brake plates 374 are close to each other or separated from each other.

[0100] Among them, among the pair of rotating brake plates 374, one can rotate in conjunction with the rotating shaft 359, and the other can prevent the rotation of the gear 373 by rotating separately from the rotating shaft 359 and move in the axial direction of the rotating shaft 359.

[0101] In more detail, the rotation preventing gear 373 can be in a ring shape and have an internal thread formed on the inner circumference, and an external thread fastened to the internal thread of the rotation preventing gear 373 is formed on the outer circumference of the main body of the other one of the pair of rotation brake plates 374, so that the above-mentioned main body can be screwed to the inner side of the rotation preventing gear 373.

[0102] Therefore, if the anti-rotation gear 373 is rotated in place by the anti-rotation motor 371 described later, the above-mentioned main body of the other of the pair of rotation brake plates 374 moves linearly in the axial direction, so that the pair of rotation brake plates 374 are in close contact with each other or spaced apart from each other.

[0103] Meanwhile, the rotation preventing gear 373 may be electrically driven by a rotation preventing motor 371 provided inside the rotation driving unit 30 .

[0104] The driving force of the rotation prevention motor 371 may be transmitted to the rotation prevention gear 373 via the rotation vibration prevention worm gear 372 and the rotation vibration prevention intermediate gear 376 .

[0105] If the rotation preventing motor 371 rotates in one direction (hereinafter defined as the "locking direction"), the rotation vibration preventing worm gear 372 and the rotation vibration preventing intermediate gear 376 rotate in one direction, and the rotation preventing gear 373 rotates in the locking direction, so that a pair of rotating brake plates 374 are tightly attached to each other, thereby preventing the rotating shaft 359 from rotating at will.

[0106] On the contrary, if the rotation preventing motor 371 rotates in another direction (hereinafter defined as the "lock release direction"), the rotation vibration preventing worm gear 372 and the rotation vibration preventing intermediate gear 376 rotate in the other direction, and the rotation preventing gear 373 rotates in the lock release direction, and a pair of rotating brake plates 374 that are in a state of close contact with each other are separated from each other, so that the rotating shaft 359 can be converted into a state where it can rotate (rotate).

[0107] As described above, in the vibration prevention parts 270 and 370, in the case of the tilting unit 100, the mutual friction of a pair of tilting brake plates 274 can be utilized, or in the case of the tilting drive unit 200, the mutual friction of a pair of rotating brake plates 374 can be utilized to prevent the tilting axis 259 and the rotating axis 359 from rotating at will, which can prevent the tilting unit 100 and the tilting drive unit 200 from rotating at will due to small vibrations caused by the external environment, and further, prevent the set direction of the antenna A from changing at will.

[0108] On the other hand, although not shown in the figure, a tilt detection unit for detecting the tilt rotation amount of the tilt unit 100 and a tilt pressure detection unit for detecting the tilt pressure transmitted through the tilt unit 100 may be respectively provided inside the rotating outer cover 231 of the tilt drive unit 200, and a rotation detection unit for detecting the rotation rotation amount of the tilt drive unit 200 and a rotation pressure detection unit for detecting the rotation pressure transmitted through the tilt drive unit 200 may be respectively provided in the combined outer cover 331 of the rotation drive unit 30.

[0109] Among them, the above-mentioned tilt rotation amount detected by the above-mentioned tilt detection part can be the rotation angle of the rotation axis of the tilt rotation motor 251, the above-mentioned rotation rotation amount detected by the above-mentioned rotation detection part can be the rotation angle of the rotation axis of the rotation rotation motor 351, the above-mentioned tilt pressure detected by the above-mentioned tilt pressure detection part can be the close contact force (friction force) of a pair of tilt brake plates 274, and the above-mentioned rotation pressure detected by the above-mentioned rotation pressure detection part can be the close contact force (friction force) of a pair of rotation brake plates 374.

[0110] Furthermore, although not shown, the present invention may further include an image detection unit, disposed on an outer surface of the antenna clamping device 10, or at a location capable of externally capturing the antenna A itself or the rotational state of the antenna A. This unit detects the state of the antenna A before and after rotation by the antenna clamping device 10 in the form of image data or video data. For example, the image detection unit may be a camera, and may output the image data or video data captured in real time via a display unit. The display unit may be disposed within the image detection unit itself, such as the camera, or may be a separate display unit, described below. The display unit may output the rotational state of the antenna A as a still image, and may output the states of the antenna A before and after rotation as images or video data.

[0111] Hereinafter, the tilt detection unit, the rotation detection unit, the tilt pressure detection unit, the rotation pressure detection unit, and the image detection unit are collectively referred to as a “detection unit”.

[0112] In the case of the detection unit formed by the tilt detection unit and the rotation detection unit, the rotation angles of the tilt unit 100 and the tilt driving unit 200 can be detected respectively.

[0113] At the same time, the tilting pressure detecting unit and the rotation pressure detecting unit can detect the pressure value changed by the external force provided from the outside or the shaking caused by external environmental factors in the fixed state of the current tilting rotation and the completed rotation.

[0114] Furthermore, as described above, the image detection unit may capture and detect the entire image of the antenna A before and after rotation.

[0115] On the other hand, the antenna clamping device 10 according to one embodiment of the present invention may further include a display for displaying the detection value detected by the detection unit so that it can be visually confirmed in a remote control center described later.

[0116] The display unit displays the rotational status of the antenna A captured by the detection unit, particularly the image detection unit, in real time. As described above, the display unit can be provided within the image detection unit itself, such as a camera, or separately at a remote control center. This allows operators to visually confirm the current status of the antenna A and precisely control the rotation of the antenna A.

[0117] Figure 8 1 is a side view showing the front and rear tilt states of the antenna clamping device according to one embodiment of the present invention. Figure 9 1 is a plan view showing the states of the antenna clamping device before and after rotation according to one embodiment of the present invention.

[0118] When the antenna clamping device 10 according to one embodiment of the present invention is used as a medium to adjust the vertical rotation (tilt rotation) of the antenna A provided at the front end of the arm unit 500, as shown in FIG. Figure 8 As shown in parts (a) and (b) of FIG. 1 , the tilting driving unit 200 can be driven to rotate the tilting unit 100 in the up-down direction.

[0119] Meanwhile, when the antenna clamping device 10 according to an embodiment of the present invention is used as a medium to adjust the horizontal rotation (rotation) of the antenna A provided at the front end of the arm unit 500, as shown in FIG. Figure 9 As shown in parts (a) and (b) of FIG. 3 , driving the rotation drive unit 30 can cause the tilt drive unit 200 to rotate toward the tilt drive unit 200 .

[0120] The tilt driving unit 200 and the rotation driving unit 30 may be driven independently or simultaneously to adjust the direction of the antenna A in a short time.

[0121] like Figure 8 Part (b) and Figure 9 As shown in part (b), after the direction of antenna A is adjusted, the tilting vibration prevention part 270 and the rotational vibration prevention part 370 are driven to make a pair of tilting brake plates 274 contact each other and a pair of rotational brake plates 374 contact each other in order to prevent the shaking (play) of antenna A caused by small vibrations transmitted from the outside.

[0122] Figure 10a and Figure 10b To illustrate various examples of control flow between a remote control center and a radio unit, Figure 11 A control block diagram showing the relationship between the control unit, the rotation adjustment unit, and the vibration prevention unit, Figure 12 A control block diagram showing the control relationship within the antenna clamping device is shown below: Figure 13 To show the control block diagram based on the specific control relationship between the motor and the detection unit, Figure 14 FIG. 1 is a control block diagram illustrating a method for controlling an antenna clamping device according to an embodiment of the present invention.

[0123] Reference Figure 10a and Figure 10b The control method of the antenna clamping device according to one embodiment of the present invention can be executed by a remote control center that remotely controls the operation of the motors 251 and 351 of the rotation adjustment parts 250 and 350 and the motors 271 and 371 of the vibration prevention parts 270 and 370.

[0124] Reference Figure 10a In a mobile communication network, a base station is a combination of a digital unit (DU) responsible for digital signal processing and a radio unit responsible for transmitting and receiving radio waves. Each unit is equipped with a base station to transmit signals to the wireless terminals carried by consumers.

[0125] The digital unit receives data from an IP network (not shown) via a wired connection, applies appropriate digital signal processing to the data, and then transmits it to the radio unit via a mobile fronthaul section. Each radio unit that receives data from the digital unit forms a small coverage area and delivers data to each wireless terminal via a wireless link.

[0126] like Figure 10a As shown, the remote control center can remotely control the operation of the motors 251 and 351 of the rotation adjustment parts 250 and 350 and the motors 271 and 371 of the vibration prevention parts 270 and 370 through the mobile communication network.

[0127] However, the above remote control center does not necessarily have to use the above mobile communication network. Figure 10bAs shown, a separate relay device may be used instead of the mobile communication network. The relay device is connected to the remote control center via wireless communication, thereby allowing a worker to remotely and wirelessly control the operation of the motors 251, 351 of the rotation adjustment units 250, 350 and the motors 271, 371 of the vibration prevention units 270, 370 using a system terminal (not shown) that can execute and operate a system related to the remote control center.

[0128] On the other hand, refer to Figure 11 The antenna clamping device according to one embodiment of the present invention may further include a control unit 600 (controller) for controlling the motors 251 and 351 of the rotation adjustment units 250 and 350 and the motors 271 and 371 of the vibration prevention units 270 and 370 .

[0129] The control unit 600 can control the rotation adjusting units 250 and 350 to adjust the tilting angle of the tilting unit 100 and the rotation angle of the tilting driving unit 200 , and can also control the vibration preventing units 270 and 370 to prevent the tilting unit 100 and the tilting driving unit 200 from rotating arbitrarily.

[0130] At the same time, refer to Figure 11 and Figure 12 The antenna clamping device according to one embodiment of the present invention may further include an information receiving unit 610. When the tilting unit 100 tilts and the tilt driving unit 200 rotates by rotating the adjusting units 250 and 350, the information receiving unit 610 may receive information on the tilting angle of the tilting unit 100 and the rotation angle of the tilt driving unit 200 and transmit the information to the control unit 600.

[0131] The control unit 600 may function as a motor control unit 600 for controlling the tilting motor 251 provided for the tilting unit 100 to tilt and rotate, and the rotation motor 351 provided for the rotation of the tilt driving unit 200 .

[0132] Furthermore, the control unit 600 can confirm the current rotation state of the antenna A in real time through the detection unit formed by the angle detection unit, the pressure detection unit, and the image detection unit. Furthermore, the control unit 600 can control the operation of the tilting motor 251 and the rotating motor 351 while being remotely monitored in real time via the display unit of the remote control center.

[0133] Reference Figure 13The control unit 600 can simultaneously receive the tilt angle information of the tilt unit 100 and the rotation angle information of the tilt drive unit 200 based on the direction information of the antenna A from the information receiving unit 610. At the same time, it can receive the operation information and rotation angle and pressure value information transmitted from the rotation adjustment units 250, 350 and the vibration prevention units 270, 370 from the detection unit 620 to control the operation of the motors composed of the rotation motors 251, 351 and the rotation prevention motors 271, 371. Preferably, the control of the above-mentioned motors is controlled by pulse width modulation (PWM) signals.

[0134] Reference Figures 11 to 14 In more detail, if the control unit 600 receives the angle information of the tilting unit 100 and the angle information of the tilting driving unit 200 that causes the control unit 600 to operate from the information receiving unit 610, the rotation prevention motors 271, 371 of the vibration prevention units 270, 370 in the locked state are operated through the current pair of tilting brake plates 274 and the pair of rotating brake plates 374 to separate the pair of brake plates 274 from each other and the pair of brake plates 374 from each other, thereby changing the vibration prevention units 270, 370 to the unlocked state.

[0135] In this case, the control unit 600 operates the rotation prevention motors 271 and 371 of the vibration prevention units 270 and 370 until the pressure values detected from the above-mentioned tilt pressure detection unit and the rotation pressure detection unit in the detection unit 620 are respectively less than the set value (Threshold). When the above-mentioned pressure values detected from the above-mentioned tilt pressure detection unit and the rotation pressure detection unit are respectively less than the above-mentioned set values, the operation of the rotation prevention motors 271 and 371 can be terminated.

[0136] Next, when the operation of the rotation preventing motors 271 and 371 is terminated, the control unit 600 operates the rotation motors 251 and 351 of the rotation regulating units 250 and 350 until the detection angle value detected by the detection unit 620 matches the reception angle value.

[0137] Moreover, when the detection angle value detected from the detection unit 620 is consistent with the received angle value, the control unit 600 terminates the operation of the rotation motors 251, 351 of the rotation adjustment unit 250, 350, and makes the rotation prevention motors 271, 371 of the vibration prevention unit 270, 370 work again until the pressure value detected by the detection unit 620 in the tilt fixed position of the tilt unit 100 and the rotation fixed position of the tilt drive unit 200 is greater than the set value. When the pressure value detected from the detection unit 620 is greater than the set value, the operation of the rotation prevention motors 271, 371 of the vibration prevention unit 270, 370 is terminated.

[0138] In the control state of the rotation adjustment parts 250, 350 and the vibration prevention parts 270, 370 based on the above-mentioned control part 600, the staff can visually confirm the changed angle of the antenna A through the display part set in the above-mentioned remote control center or the display part set in the system terminal linked to the above-mentioned remote control center.

[0139] Figure 15 This is a control flow chart showing an embodiment of a control method of the antenna clamping device of the present invention.

[0140] The control method of the clamping device for an antenna device according to an embodiment of the present invention executed in the above manner is summarized as follows.

[0141] A control method for a clamping device for an antenna device according to an embodiment of the present invention includes: an angle information receiving step S10, receiving rotation angle information of the tilt unit 100 and the tilt drive unit 200 from a remote control center; a rotation adjustment unit control step S30, controlling the operation of the rotation adjustment units 250 and 350 according to the tilt receiving angle and the rotation receiving angle of the tilt unit 100 and the tilt drive unit 200 received through the angle information receiving step S10; and a vibration prevention unit control step S20, causing the vibration prevention units 270 and 370 to operate in a manner that can execute the rotation adjustment unit control step S30 to release the rotation locking state of the tilt unit 100 and the tilt drive unit 200.

[0142] As described above, the angle information receiving step S10 may be a step in which the control unit remotely receives the angle information via a mobile communication network based on the remote control center. However, the present invention is not limited thereto. The angle information receiving step may also be a step in which the control unit remotely receives the angle information via wireless communication between the remote control center and the relay device.

[0143] On the other hand, the received angle value received in the angle information receiving step S10 may be only the tilt rotation information of the tilt unit 100 according to the set direction information of the set antenna, or may be only the rotation information of the tilt drive unit 200, or may include the respective rotation information of both (i.e., the tilt unit 100 and the tilt drive unit 200).

[0144] In the rotation adjustment unit control step S30, the initially set tilt fixed position of the tilt unit 100 and the initially set rotation fixed position of the tilt driving unit 200 can be used as starting points. Therefore, the control unit (motor control unit) first operates the tilt rotation adjustment unit 250 of the tilt unit 100 and then operates the rotation adjustment unit 350. It can also be controlled in the opposite order, or the tilt rotation adjustment unit 250 and the rotation adjustment unit 350 can be controlled at the same time.

[0145] On the other hand, the vibration prevention unit control step S20 is a step executed before and after the rotation adjustment unit control step in time, and may include a front vibration prevention unit control step S21 executed before the rotation adjustment unit control step S30 and a rear vibration prevention unit control step S22 executed after the rotation adjustment unit control step S30.

[0146] The front vibration prevention unit control step S21 is a step of operating the vibration prevention units 270, 370 in a manner that converts the state locked in the tilt fixed position or the rotation fixed position into a released state before the rotation motors 251, 351 of the rotation adjustment units 250, 350 of the tilt unit 100 and the tilt drive unit 200 are operated through the rotation adjustment unit control step S30.

[0147] On the contrary, the rear vibration prevention part control step S22 is the following step, that is, through the rotation adjustment part control step S30, if the tilt unit 100 and the tilt drive unit 200 complete the rotation to the tilt fixed position and the rotation fixed position according to the received angle value, the vibration prevention parts 270 and 370 are operated in a manner of converting from the unlocked state to the locked state again.

[0148] Meanwhile, the control method of the antenna clamping device according to an embodiment of the present invention may further include a rotation confirmation step, in which the rotation state of the antenna A is confirmed by displaying the image data or video data detected by the image detection unit on the display unit.

[0149] The above-mentioned rotation confirmation step can be defined as the following step, that is, confirming whether the rotation work of the antenna based on the control unit is completed based on the video data related to the real-time rotation state of the antenna detected by the image detection unit or the image related to the state before and after the rotation of the antenna.

[0150] As described above, the antenna clamping device of one embodiment of the present invention includes: a tilting rotation motor 251, used to rotate the antenna A in the upward and downward directions; a tilting rotation prevention motor 271, used to lock or unlock the upward and downward rotation of the antenna A; a rotating rotation motor 351, used to rotate the antenna A in the horizontal direction; a rotating rotation prevention motor 371, used to lock or unlock the horizontal rotation of the antenna A; and a control unit 600, which controls the tilting rotation motor 251, the tilting rotation prevention motor 271, the rotating rotation motor 351 and the rotating rotation prevention motor 371 to adjust the direction of the antenna A.

[0151] The antenna clamping device of one embodiment of the present invention may also include an information receiving unit 610, which receives the rotation angle information of the antenna A transmitted from the above-mentioned remote control center and transmits it to the control unit 600. The control unit 600 controls the tilt rotation motor 251, the tilt rotation prevention motor 271, the rotation rotation motor 351 and the rotation rotation prevention motor 371 based on the rotation angle information of the antenna A received from the information receiving unit 610.

[0152] The information receiving unit 610 may receive the rotation angle information of the antenna A transmitted from the remote control center via the mobile communication network.

[0153] The information receiving unit 610 may receive the rotation angle information of the antenna A transmitted from the remote control center via the relay device.

[0154] If the rotation angle information of antenna A is input from the information receiving unit 610, the control unit 600 controls the tilt rotation prevention motor 271 and the rotation rotation prevention motor 371 to unlock the up and down rotation of antenna A and the horizontal rotation of antenna A, and then controls the tilt rotation motor 251 and the rotation rotation motor 351 to adjust the up and down rotation angle of antenna A and the horizontal rotation angle of antenna A.

[0155] The control unit 600 may preferentially control one of the tilting and rotating preventing motor 271 and the rotation preventing motor 371 , and may preferentially control one of the tilting and rotating motor 251 and the rotational rotating motor 351 .

[0156] The control unit 600 can simultaneously control the tilting and rotating prevention motor 271 and the rotation preventing motor 371 , and can simultaneously control the tilting and rotating motor 251 and the rotation preventing motor 351 .

[0157] The antenna clamping device according to one embodiment of the present invention may further include the angle detection unit (angle detection sensor) for detecting the rotation angle of the rotation shaft of the tilt motor 251 and the rotation angle of the rotation shaft of the rotation motor 351. After the control unit 600 unlocks the vertical rotation of the antenna A and the horizontal rotation of the antenna A, it operates the tilt motor 251 and the rotation motor 351 until the detected angle value transmitted by the angle detection unit matches the received angle value transmitted by the information receiving unit 610, thereby adjusting the vertical rotation angle of the antenna A and the horizontal rotation angle of the antenna A. The angle detection unit may include the tilt detection unit and the rotation detection unit.

[0158] The antenna clamping device according to one embodiment of the present invention may further include the pressure detection unit (pressure detection sensor) described above, which is configured to detect pressure applied to lock the vertical rotation of antenna A and pressure applied to lock the horizontal rotation of antenna A. Upon receiving rotation angle information of antenna A from information receiving unit 610, control unit 600 operates tilting and rotation preventing motor 271 and rotation preventing motor 371 until the pressure value transmitted from the pressure detection unit falls below a value set by control unit 600, thereby unlocking the vertical and horizontal rotation of antenna A. The pressure detection unit may include the tilting pressure detection unit and the rotation pressure detection unit.

[0159] After controlling the tilting motor 251 and the rotating motor 351 to adjust the vertical rotation angle and the horizontal rotation angle of the antenna A, the control unit 600 operates the tilting anti-rotation motor 271 and the rotating anti-rotation motor 371 until the pressure value transmitted from the above-mentioned pressure detection unit is greater than the value set in the control unit 600, thereby locking the vertical rotation and the horizontal rotation of the antenna A.

[0160] The antenna clamping device of one embodiment of the present invention may further include the above-mentioned image detection unit, which is used to detect the rotation state of the antenna A through video data or image data detection. The control unit 600 can transmit the above-mentioned video data or the above-mentioned image data detected by the above-mentioned image detection unit to a display unit set in the above-mentioned remote control center or a display unit set in a system terminal linked to the above-mentioned remote control center.

[0161] According to the antenna clamping device and control method thereof of one embodiment of the present invention having the above structure, workers do not need to go directly to a high place to adjust the direction of the antenna A set at a high place. The direction of the antenna A can be remotely adjusted through a remote control center (or a system terminal linked thereto) using a mobile communication network or a relay device as a medium, thereby greatly improving the convenience of the operation.

[0162] An embodiment of the control method for an antenna clamping device according to the present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above-described embodiment. Persons skilled in the art may make modifications and implement the invention within the scope of equivalents. Therefore, the true scope of protection of the present invention is defined by the scope of the claims.
