Description

Technical Field

[0001] The present invention belongs to the technical field of antenna adjustment, and particularly relates to an angle adjustment device and method for a bicone antenna. Background Art

[0002] A bicone antenna is an omnidirectional antenna with a symmetric dipole structure and belongs to a non-frequency-variable antenna. Due to its wide frequency band, good omnidirectionality, and relatively stable radiation pattern within the working bandwidth, it is very popular in the ultra-wideband field.

[0003] Existing miniaturized ultra-wideband bicone antennas have been improved on the basis of the traditional bicone structure, with the addition of a terminal ring and a metal sleeve, making the antenna have better broadband characteristics. However, in order to improve the signal strength of the transmitting bicone antenna, it is necessary to adjust the angle of the bicone antenna in real time according to the surrounding environmental interference factors. During the process of repeatedly adjusting the angle of the bicone antenna, the mechanical components of the antenna (such as the rotating joints of the pan-tilt and the bolts of the mounting bracket) will be subject to frequent friction and stress. This easily leads to component wear, and over time, it will affect the accuracy and reliability of the adjustment device, which has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] Object of the Invention: In order to solve the problem of poor adjustment accuracy and reliability caused by component wear, the present invention provides an angle adjustment device for a bicone antenna.

[0005] Technical Solution: To achieve the above object, the technical solution adopted by the present invention is as follows: An angle adjustment device for a bicone antenna, comprising a base, a horizontal plane rotation mechanism, a vertical plane rotation mechanism, a detection unit, and a control unit. The horizontal plane rotation mechanism is arranged on the base, the vertical plane rotation mechanism is arranged on the horizontal plane rotation mechanism, and the vertical plane rotation mechanism includes a vertical plane rotation component and a pressing and positioning component. The bicone antenna is installed on the vertical plane rotation component, wherein: The horizontal plane rotation mechanism is used to rotate the vertical plane rotation component and the pressing and positioning component in the horizontal plane.

[0006] The vertical plane rotation component is used to rotate the bicone antenna in the vertical plane.

[0007] The pressing and positioning component is used to press and fix the vertical plane rotation component after rotation.

[0008] The detection unit is used to detect the signal strength of the bicone antenna and the rotational wear of the vertical plane rotation component.

[0009] The control unit evaluates high-level wear and low-level wear of the wear based on the detected rotational wear. When it is high-level wear, wear adjustment is performed on the vertical surface rotating component. When it is low-level wear, the horizontal plane rotating mechanism and the vertical surface rotating component are controlled according to the detected signal strength to rotate the dual-cone antenna in the horizontal plane and the vertical plane. After the rotation is completed, the extrusion positioning component is controlled to perform extrusion fixation.

[0010] Preferably: The vertical surface rotating component includes a mounting base, a second connecting plate, a first connecting plate, a mounting shell, a first cylinder, a rack, a gear, a connecting shaft, a connecting seat, a moving tooth, a micro gear, and a fourth motor. The second connecting plate and the first connecting plate are fixedly installed on the horizontal plane rotating mechanism. The connecting seat is installed on the second connecting plate. The mounting base is rotatably installed on the connecting seat through a bearing. The mounting base is used to mount the dual-cone antenna. The mounting shell is installed on the first connecting plate. The moving tooth is slidably installed at the bottom of the mounting shell through a chute. The micro gear and the fourth motor are installed at the bottom of the mounting shell, and the micro gear is in transmission connection with the fourth motor. The micro gear is in meshing transmission connection with the moving tooth. The first cylinder is installed on the moving tooth. The rack is installed at the driving end of the first cylinder. One end of the connecting shaft is fixedly connected to the mounting base, and the other end is fixedly connected to the gear. The gear is in meshing connection with the rack.

[0011] Preferably: The extrusion positioning component includes a third connecting plate, a second cylinder, an extrusion disc, and an extrusion plate. The third connecting plate is fixedly installed on the connecting seat through a support column. An arc-shaped through hole is provided on the connecting seat. The fixed part of the second cylinder is installed on the third connecting plate. The extrusion disc is installed at the telescopic end of the second cylinder. The extrusion plate is installed at the telescopic end of the second cylinder between the connecting seat and the third connecting plate. When the telescopic end of the second cylinder extends to the first limit position, the extrusion disc abuts against the mounting base, and the extrusion plate abuts against the connecting seat. When the telescopic end of the second cylinder retracts to the second limit position, the extrusion disc separates from the mounting base, and the extrusion plate separates from the connecting seat.

[0012] Preferably: The horizontal plane rotating mechanism includes a horizontal plane rotating component. The horizontal plane rotating component includes a housing, a second motor, a passive gear, a clutch two, and an active gear. The housing is installed on the base. The second motor is installed on the housing. The passive gear and the active gear are arranged inside the housing. The passive gear is coaxially rotatably connected to the mounting shaft. The second motor is in transmission connection with the active gear through the clutch two.

[0013] Preferably: The detection unit includes a signal strength detection module, a distance sensor, a first angle sensor, a second angle sensor, and a third angle sensor. The signal strength detection module is connected to the dual-cone antenna. The signal strength detection module is used to detect the signal strength of the dual-cone antenna.

[0014] The distance sensor is fixedly installed on the top of the rack, and the distance sensor is used to detect the moving distance between the rack and the top of the installation shell.

[0015] The third angle sensor is fixedly installed on one side of the gear, and the third angle sensor is used to detect the rotation angle of the gear, denoted as the third rotation angle.

[0016] The first angle sensor is fixedly installed on the driving gear, and the first angle sensor is used to detect the rotation angle of the driving gear, denoted as the first rotation angle.

[0017] The second angle sensor is fixedly installed on the driven gear, and the second angle sensor is used to detect the rotation angle of the driven gear, denoted as the second rotation angle.

[0018] Preferably: The control unit includes a wear level determination module, a wear adjustment module, a signal strength control module, and an alarm module, where: The wear level determination module determines the wear level between the rack and the gear based on the moving distance and the third rotation angle. When the moving distance is less than or equal to the preset moving distance threshold and the third rotation angle is less than or equal to the preset third rotation angle threshold, it indicates that the wear level between the rack and the gear is low-level wear. When the moving distance is greater than the preset moving distance threshold or the third rotation angle is greater than the preset third rotation angle threshold, it indicates that the wear level between the rack and the gear is high-level wear.

[0019] The wear adjustment module is used to control the fourth motor to drive the micro gear to rotate when there is high-level wear. The micro gear drives the moving tooth to move, and then drives the rack to move towards the gear through the first cylinder until the pre-tightening force between the rack and the gear reaches the preset value and stops moving.

[0020] The signal strength control module is used to control the horizontal plane rotation mechanism and the vertical plane rotation assembly to rotate the biconical antenna in the horizontal plane and the vertical plane according to the detected signal strength of the biconical antenna, the required signal strength, and when there is low-level wear, so as to adjust the required angle of the biconical antenna.

[0021] The alarm module determines the meshing state of the driving gear and the driven gear based on the first rotation angle and the second rotation angle. If the first rotation angle and the second rotation angle are inconsistent, it indicates that the meshing state of the driving gear and the driven gear is poor, and an alarm notification is issued.

[0022] Preferably, the horizontal plane rotation mechanism includes a support assembly, and the support assembly includes a mounting shaft, a mounting sleeve, and a support frame. The mounting shaft is mounted on the base through a bearing at the top of the housing. A plurality of first mounting holes are formed in the mounting shaft, and a second mounting hole is formed in the mounting sleeve. The mounting sleeve is sleeved on the mounting shaft, and the first mounting hole corresponds to the second mounting hole. The mounting sleeve and the mounting shaft are fixedly connected by bolts through the first mounting hole and the second mounting hole. The support frame is fixedly mounted on the mounting sleeve, and the second connecting plate and the first connecting plate are fixed to the support frame.

[0023] Preferably, an elastic rubber layer is provided on the extrusion friction surfaces of the extrusion disc and the extrusion plate.

[0024] Preferably, the connecting seat is composed of two groups of brackets.

[0025] An angle adjustment method for a biconical antenna, using the above-mentioned angle adjustment device for a biconical antenna, includes the following steps: Step 1, system initialization.

[0026] Step 2, initially, by default, the wear level between the rack and the gear is high wear. The wear adjustment module controls the fourth motor to drive the micro gear to rotate according to the high wear information. The micro gear drives the moving tooth to move, and then drives the rack to move towards the gear through the first cylinder until the pre-tightening force between the rack and the gear reaches the preset value and stops moving. At this time, the wear level between the rack and the gear is low wear.

[0027] Step 3, the detection unit works. The signal strength detection module detects the signal strength of the biconical antenna, the distance sensor detects the moving distance between the rack and the top of the mounting shell, and the angle sensor three detects the rotation angle of the gear, denoted as the rotation angle three. The angle sensor one detects the rotation angle of the driving gear, denoted as the rotation angle one, and the angle sensor two is used to detect the rotation angle of the driven gear, denoted as the rotation angle two.

[0028] Step 3, if the signal strength of the biconical antenna is not within the required signal strength area of the biconical antenna and the wear level is low, first, the signal strength regulation module controls the second cylinder to retract. When the telescopic end of the second cylinder retracts to the second limit position, the extrusion disc is separated from the mounting seat, and the extrusion plate is separated from the connecting seat. Secondly, the signal strength regulation module controls the horizontal plane rotation assembly to work: start the second motor to drive the driving gear to rotate, thereby driving the driven gear to rotate, and then driving the mounting shaft to rotate on the horizontal plane. When the mounting shaft rotates, the vertical plane rotation mechanism is driven by the support frame to rotate on the horizontal plane. Finally, the signal strength regulation module first controls the vertical plane rotation mechanism to work: start the first cylinder, the telescopic end of the first cylinder extends and retracts to drive the rack to move, drive the gear to rotate through the rack, and then drive the connecting shaft to rotate on the vertical plane. When the connecting shaft rotates, it drives the mounting seat to rotate around the connecting seat, so as to realize the rotation of the biconical antenna on the horizontal plane and the vertical plane until the biconical antenna rotates to the optimal position and stops.

[0029] Step 4, after the biconical antenna rotates to the optimal position and stops, the signal strength regulation module controls the second cylinder to extend. When the telescopic end of the second cylinder extends to the first limit position, the extrusion disc abuts against the mounting seat, and the extrusion plate abuts against the connecting seat.

[0030] Step 5, the wear level determination module determines the wear level between the rack and the gear according to the moving distance and the rotation angle three. When the moving distance is less than or equal to the preset moving distance threshold and the rotation angle three is less than or equal to the preset rotation angle threshold three, it indicates that the wear level between the rack and the gear is low wear. When the moving distance is greater than the preset moving distance threshold or the rotation angle three is greater than the preset rotation angle threshold three, it indicates that the wear level between the rack and the gear is high wear.

[0031] The present invention has the following beneficial effects compared with the prior art: Since the vertical plane rotation mechanism includes a vertical plane rotation assembly and an extrusion positioning assembly, the regulation unit evaluates the wear as high wear and low wear according to the detected rotational wear. In the case of high wear, wear adjustment is performed on the vertical plane rotation assembly. In the case of low wear, the horizontal plane rotation mechanism and the vertical plane rotation assembly are controlled according to the detected signal strength to rotate the biconical antenna on the horizontal plane and the vertical plane. After the rotation is completed, the extrusion positioning assembly is controlled to perform extrusion fixation. On the one hand, the vertical plane rotation assembly is extruded and fixed after rotation by the extrusion positioning assembly. On the other hand, wear adjustment is performed on the vertical plane rotation assembly to improve the accuracy of the angle adjustment of the biconical antenna. Description of the Drawings

[0038] The vertical plane rotation assembly is used to rotate the biconical antenna 13 in the vertical plane.

[0039] In another embodiment, as Figure 1 , 2, as shown in FIGS. 3, the vertical plane rotation assembly includes a mounting base 10, a second connecting plate 11, a first connecting plate 12, a mounting shell 14, a first cylinder 16, a rack 17, a gear 18, a connecting shaft 19, a connecting seat 20, a moving tooth 35, a micro gear 36, and a fourth motor 37.

The connecting seat 20 is installed on the second connecting plate 11. The mounting base 10 is rotatably installed on the connecting seat 20 through a bearing. The mounting base 10 is used to install a biconical antenna 13. The mounting shell 14 is installed on the first connecting plate 12. The moving tooth 35 is slidably installed at the bottom of the mounting shell 14 through a chute. The micro gear 36 and the fourth motor 37 are installed at the bottom of the mounting shell 14, and the micro gear 36 is in transmission connection with the fourth motor 37. The micro gear 36 is in meshing transmission connection with the moving tooth 35. The first cylinder 16 is installed on the moving tooth 35. The rack 17 is installed at the driving end of the first cylinder 16. One end of the connecting shaft 19 is fixedly connected to the mounting base 10, and the other end is fixedly connected to the gear 18. The connecting seat 20 and the connecting shaft 19 are in bearing connection. The gear 18 is in meshing connection with the rack 17. Starting the first cylinder 16 can drive the rack 17 to move up and down. The up and down movement of the rack 17 can drive the gear 18 to rotate, and then drive the connecting shaft 19 to rotate. The rotation of the connecting shaft 19 drives the mounting base 10 to rotate around the connecting seat 20, and the rotation of the mounting base 10 drives the biconical antenna 13 to rotate.

[0041] The pressing and positioning assembly is used to press and fix the vertical plane rotation assembly after rotation.

[0042] In another embodiment, as Figure 1 、 2As shown in FIGS. 4, the extrusion positioning assembly includes a third connecting plate 21, a second cylinder 22, an extrusion disc 24, and an extrusion plate 34. The third connecting plate 21 is fixedly installed on the connecting seat 20 through a support column. The third connecting plate 21 is disposed in the middle of the connecting seat 20, and the connecting seat 20 is composed of two groups of brackets. A through arc groove hole 23 is formed in the connecting seat 20. The fixed part of the second cylinder 22 is installed on the third connecting plate 21. Two groups of second cylinders 22 are fixed on both the upper and lower sides of the third connecting plate 21. An extrusion disc 24 and an extrusion plate 34 are fixed on each group of second cylinders 22. Specifically, the extrusion disc 24 is installed on the telescopic end of the second cylinder 22, and an elastic rubber layer is provided on one side of the extrusion disc 24 facing the mounting seat 10. The extrusion plate 34 is installed on the telescopic end of the second cylinder 22 between the connecting seat 20 and the third connecting plate 21, and an elastic rubber layer is provided on one side of the extrusion plate 34 facing the connecting seat 20. Among them, the extrusion disc 24 is disposed in the arc groove hole 23, the extrusion plate 34 is located outside the brackets of the connecting seat 20, and the extrusion disc 24 passes through the arc groove hole 23 and contacts the inner wall of the mounting seat 10. When the telescopic end of the second cylinder 22 extends to the first limit position, the extrusion disc 24 and the mounting seat 10 are tightly abutted against each other, and the extrusion plate 34 and the connecting seat 20 are tightly abutted against each other. When the telescopic end of the second cylinder 22 retracts to the second limit position, the extrusion disc 24 and the mounting seat 10 are separated from each other, and the extrusion plate 34 and the connecting seat 20 are separated from each other. By starting the elongation of the second cylinder 22, the extrusion disc 24 contacts the inner wall of the mounting seat 10, and the extrusion plate 34 contacts the inner walls of the brackets on both sides of the connecting seat 20, increasing the pressure between the extrusion plate 34 and the inner walls of the brackets on both sides of the connecting seat 20, further ensuring the stability of the mounting seat 10, so as to ensure the stability of the double-cone antenna 13 in place and ensure the signal strength.

[0043] The detection unit is used to detect the signal strength of the double-cone antenna and the rotational wear of the vertical plane rotation assembly.

[0044] The detection unit includes a signal strength detection module, a distance sensor 29, a first angle sensor 32, a second angle sensor 31, and a third angle sensor 33. The signal strength detection module is connected to the double-cone antenna, and the signal strength detection module is used to detect the signal strength of the double-cone antenna.

[0045] The distance sensor 29 is fixedly installed on the top of the rack 17, and the distance sensor 29 is used to detect the moving distance between the rack 17 and the top of the mounting shell 14.

[0046] The third angle sensor 33 is fixedly installed on one side of the gear 18, and the third angle sensor 33 is used to detect the rotation angle of the gear 18, denoted as the third rotation angle.

[0047] The first angle sensor 32 is fixedly installed on the driving gear 30, and the first angle sensor 32 is used to detect the rotation angle of the driving gear 30, denoted as the first rotation angle.

[0048] The second angle sensor 31 is fixedly installed on the driven gear 25, and the second angle sensor 31 is used to detect the rotation angle of the driven gear 25, denoted as the second rotation angle.

[0049] The control unit evaluates high-level wear and low-level wear of the wear according to the detected rotational wear. In the case of high-level wear, wear adjustment is performed on the vertical surface rotating assembly. In the case of low-level wear, the horizontal plane rotating mechanism and the vertical surface rotating assembly are controlled according to the detected signal strength to rotate the dual-cone antenna in the horizontal plane and the vertical plane. After the rotation is completed, the extrusion positioning assembly is controlled to perform extrusion fixation.

[0050] The control unit includes a wear level determination module, a wear adjustment module, a signal strength control module, and an alarm module, where: The wear level determination module is electrically connected to the distance sensor 29 and the third angle sensor 33. The wear level determination module determines the wear level between the rack 17 and the gear 18 according to the moving distance and the third rotation angle. When the moving distance is less than or equal to the preset moving distance threshold and the third rotation angle is less than or equal to the preset third rotation angle threshold, it indicates that the wear level between the rack 17 and the gear 18 is low-level wear. When the moving distance is greater than the preset moving distance threshold or the third rotation angle is greater than the preset third rotation angle threshold, it indicates that the wear level between the rack 17 and the gear 18 is high-level wear.

[0051] When the vertical surface rotating assembly is working and the first cylinder 16 starts to drive the rack 17 to work, at this time, the distance sensor 29 detects the distance between the top of the rack 17 and the mounting shell 14 and transmits it to the wear level determination module. At the same time, the third angle sensor 33 identifies the rotation angle of the gear 18 and transmits it to the wear level determination module. When the wear level determination module identifies the change in the distance between the top of the rack 17 and the mounting shell 14 and the change in the angle of the gear 18 identified by the third angle sensor 33, it judges the problems existing in the meshing state between the gear 18 and the rack 17.

[0052] Specifically, in the wear level determination module, the maximum distance L (moving distance threshold) that the rack 17 moves and the third rotation angle threshold are set. When the distance that the rack 17 moves is within the range of L and the angle of the gear 18 changes, and the third rotation angle is less than or equal to the preset third rotation angle threshold, it indicates that the wear between the gear 18 and the rack 17 is low-level wear. When the distance that the rack 17 moves is greater than the range of L, or the third rotation angle is greater than the preset third rotation angle threshold, it indicates that the wear between the gear 18 and the rack 17 is high-level wear.

[0053] The wear adjustment module is used to control the fourth motor 37 to drive the micro gear 36 to rotate when the wear is advanced. The micro gear 36 drives the moving tooth 35 to move, and then drives the rack 17 to move towards the gear 18 through the first cylinder 16 until the pre-tightening force between the rack 17 and the gear 18 reaches the preset value and stops moving.

[0054] When there is a problem with the meshing state between the gear 18 and the rack 17, that is, when the wear between the gear 18 and the rack 17 is advanced wear, the wear adjustment module transmits a signal to the fourth motor 37, so that the fourth motor 37 drives the micro gear 36 to cooperate with the moving tooth 35, and controls the rack 17 on the first cylinder 16 to move in the direction close to the gear 18, so that the left and right contact ends of the rack 17 and the gear 18 are in close contact until the pre-tightening force between the rack 17 and the gear 18 reaches the preset value and stops moving, improving the pre-tightening force between the rack 17 and the gear 18, increasing the friction force between the rack 17 and the gear 18, thereby ensuring the stability between the rack 17 and the gear 18, and further ensuring the stability of the biconical antenna 13 before maintenance.

[0055] The signal intensity regulation module is used to control the horizontal plane rotation mechanism and the vertical plane rotation assembly to rotate the biconical antenna in the horizontal plane and the vertical plane according to the detected signal intensity of the biconical antenna, the required signal intensity, and when the wear is low, so as to adjust the required angle of the biconical antenna.

[0056] Specifically, the signal intensity range is set as A - B in the signal intensity regulation module, and the signal intensity detection module in the biconical antenna 13 detects the signal intensity in real time and transmits the signal to the signal intensity regulation module for comparison with the set signal. When the signal detected in real time is within the range of A - B, it means that the signal intensity is within the range. When the signal detected in real time is not within the range of A - B, it means that there is a problem with the signal. At this time, the angle of the biconical antenna 13 needs to be adjusted to ensure the signal intensity.

[0057] Start the second motor 8 to drive the driving gear 30 to rotate, thereby driving the driven gear 25 to rotate, and then driving the mounting shaft 2 to rotate. When the mounting shaft 2 rotates, it drives the angle adjustment mechanism to rotate through the support frame 6, thereby driving the biconical antenna 13 to rotate. At the same time as the mounting shaft 2 rotates, it is also necessary to control the swing angle of the biconical antenna 13; at this time, start the first cylinder 16, and the telescopic end of the first cylinder 16 expands and contracts to drive the rack 17 to move, driving the gear 18 to rotate through the rack 17, and then driving the connecting shaft 19 to rotate. When the connecting shaft 19 rotates, it can drive the mounting seat 10 to rotate together, thereby driving the biconical antenna 13 to swing.

[0058] Since the horizontal plane rotation mechanism and the vertical plane rotation assembly operate simultaneously, driving the dual-cone antenna 13 to find the optimal position for receiving signals. If the signal received by the dual-cone antenna 13 is within the set A - B range at this time, the second motor 8 and the first cylinder 16 are stopped to make the dual-cone antenna 13 maintain a proper position.

[0059] When the dual-cone antenna 13 is in the optimal position, the second cylinder 22 is activated to extend, so that the extrusion plate 24 contacts the inner wall of the mounting seat 10 and the pressing plate 34 contacts the inner walls of the brackets on both sides of the connecting seat 20, which can increase the friction and further ensure the stability of the mounting seat 10.

[0060] The alarm module judges the meshing state of the driving gear (30) and the driven gear (25) according to the first rotation angle and the second rotation angle. If the first rotation angle and the second rotation angle are inconsistent, it means that the meshing state of the driving gear (30) and the driven gear (25) is poor, and an alarm notification is issued to inform the staff to repair through the alarm of the alarm module.

[0061] In this embodiment, the rotation angles of the driving gear 30 and the driven gear 25 are respectively detected by the second angle sensor 31 and the first angle sensor 32 to judge the meshing state of the driving gear 30 and the driven gear 25. Specifically, when the first angle sensor 32 detects the start of the driving gear 30 and transmits the signal to the alarm module, at the same time, the second angle sensor 31 also transmits the rotation angle of the driven gear 25 to the alarm module. When it is recognized that the driving gear 30 and the driven gear 25 are synchronized, it means that the meshing state of the driving gear 30 and the driven gear 25 is good. When it is recognized that there is a delay in the meshing of the driving gear 30 and the driven gear 25, it means that the meshing state of the driving gear 30 and the driven gear 25 is poor. At this time, the clutch two 27 is controlled to close by the adjustment sub-module, so that the second motor 8 is disengaged from the driving gear 30, and an alarm notification is issued to inform the staff to repair through the alarm of the alarm module. Embodiment

[0062] This embodiment discloses an angle adjustment method for a dual-cone antenna, using the above-mentioned angle adjustment device for a dual-cone antenna, including the following steps: Step 1, system initialization.

[0063] Step 2, initially, the wear level between the rack 17 and the gear 18 is defaulted to high wear. The wear adjustment module controls the fourth motor 37 to drive the micro gear 36 to rotate according to the high wear information. The micro gear 36 drives the moving tooth 35 to move, and then drives the rack 17 to move towards the gear 18 through the first cylinder 16 until the pre-tightening force between the rack 17 and the gear 18 reaches the preset value and stops moving. At this time, the wear level between the rack 17 and the gear 18 is low wear.

[0064] Step 3: The detection unit operates. The signal strength detection module detects the signal strength of the biconical antenna. The distance sensor 29 detects the moving distance between the rack 17 and the top of the mounting shell 14. The angle sensor III 33 detects the rotation angle of the gear 18, denoted as rotation angle III. The angle sensor I 32 detects the rotation angle of the driving gear 30, denoted as rotation angle I. The angle sensor II 31 is used to detect the rotation angle of the driven gear 25, denoted as rotation angle II.

[0065] Step 3: If the signal strength detected by the biconical antenna is not within the signal strength region required by the biconical antenna 13 and it is in low-level wear, first, the signal strength regulation module controls the second cylinder 22 to retract. When the telescopic end of the second cylinder 22 retracts to the second limit position, the extrusion disc 24 separates from the mounting seat 10, and the extrusion plate 34 separates from the connecting seat 20. Secondly, the signal strength regulation module controls the horizontal plane rotation assembly to operate: start the second motor 8 to drive the driving gear 30 to rotate, thereby driving the driven gear 25 to rotate, and then driving the mounting shaft 2 to rotate on the horizontal plane. When the mounting shaft 2 rotates, it drives the vertical plane rotation mechanism to rotate on the horizontal plane through the support frame 6. Finally, the signal strength regulation module first controls the vertical plane rotation mechanism to operate: at this time, start the first cylinder 16. The telescopic end of the first cylinder 16 extends and retracts to drive the rack 17 to move. The rack 17 drives the gear 18 to rotate, thereby driving the connecting shaft 19 to rotate on the vertical plane. When the connecting shaft 19 rotates, it drives the mounting seat 10 to rotate around the connecting seat 20, and further realizes the rotation of the biconical antenna 13 on the horizontal plane and the vertical plane until the biconical antenna 13 rotates to the optimal position and stops.

[0066] Step 4: After the biconical antenna 13 rotates to the optimal position and stops, the signal strength regulation module controls the second cylinder 22 to extend. When the telescopic end of the second cylinder 22 extends to the first limit position, the extrusion disc 24 abuts tightly against the mounting seat 10, and the extrusion plate 34 abuts tightly against the connecting seat 20.

[0067] Step 5: The wear level determination module determines the wear level between the rack 17 and the gear 18 based on the moving distance and rotation angle III. When the moving distance is less than or equal to the preset moving distance threshold and the rotation angle III is less than or equal to the preset rotation angle threshold III, it indicates that the wear level between the rack 17 and the gear 18 is low-level wear. When the moving distance is greater than the preset moving distance threshold or the rotation angle III is greater than the preset rotation angle threshold III, it indicates that the wear level between the rack 17 and the gear 18 is high-level wear.

[0068] In summary, the present invention can improve the accuracy and reliability of the angle adjustment of the biconical antenna.

[0069] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
