Description

Technical Field

[0001] This invention belongs to the field of antenna control and measurement and control equipment technology, and specifically relates to a portable measurement and control antenna with a variable mount. Background Technology

[0002] Telemetry and control antennas are widely used in emergency communications, satellite telemetry and control, and high-speed moving target tracking. The configuration of their mount structure directly determines the antenna's tracking range, motion accuracy, and scene adaptability, and is a key component affecting the overall performance and user experience of the equipment.

[0003] Currently, mainstream telemetry and control antenna mounting systems are mainly divided into two types: XY type and AE type. These two types of mounting systems have distinctly different motion characteristics and suitable application scenarios. The AE type mounting system adopts a classic configuration with an azimuth axis and an elevation axis, resulting in a clear overall wiring path and low transmission loss in waveguides and cables. It has a significant advantage when tracking targets such as missiles and rockets, which have high initial speeds and maintain a consistently low elevation angle. The XY type mounting system uses a configuration with two horizontal axes arranged in a cross pattern. For example, the XY-axis antenna mounting system disclosed in Chinese patent application CN102820537A enables continuous and uninterrupted signal transmission during overhead tracking, making it the preferred solution for telemetry and control scenarios involving frequent low-Earth orbit satellite overpasses.

[0004] Due to inherent limitations in their structural configurations, both existing types of mounting systems are independent, dedicated structures. A single device can only support one type of mounting, making it impossible to flexibly adjust the mounting type according to the actual tracking mission requirements. When telemetry and control bases or field mobile units face diverse target telemetry and control needs, operators must separately procure and install complete XY-type and AE-type mounting antenna systems, including servo control hardware and telemetry and control baseband. Two independent sets of equipment inevitably increase the overall system cost, while the single structure results in extremely low reusability, making it impossible to meet the requirement of switching between multiple scenarios with a single set of equipment within a limited budget.

[0005] Furthermore, traditional antennas typically use external wiring for power supply, signal, and radio frequency cables. During the long-term reciprocating motion of the mounting bracket, the cables continuously twist and bend along the axis of rotation. Specifically, with the AE-type mounting bracket, the cables continuously twist along the azimuth axis during single-axis rotation, posing a risk of sheath wear and internal wire breakage. The dual-axis cross-twisting of the XY-type mounting bracket further increases the complexity of the wiring layout. Cables are subjected to multi-directional bending and twisting over time, resulting in faster wear and, in severe cases, cable entanglement and jamming, directly impacting system reliability and equipment lifespan. Summary of the Invention

[0006] Therefore, the purpose of this invention is to propose a portable measurement and control antenna with a variable mount, in order to solve the technical problems of existing portable measurement and control antennas, which suffer from low equipment reuse rate and high procurement cost due to the incompatibility of different motion mounts, and are prone to cable entanglement and wear during dual-axis movement.

[0007] To solve the above problems, the present invention provides a technical solution for a portable telemetry and control antenna with a variable mount:

[0008] A portable telemetry and control antenna with a variable mount includes a support assembly, a first drive motor, a replaceable structural adapter, a second drive motor, a signal processing and control assembly, and an antenna feed assembly. The first drive motor is detachably mounted on the support assembly. The first drive motor has a first fixed part and a first rotating part. The structural adapter is detachably fixed on the first rotating part. By replacing the structural adapter with different configurations and adjusting the mounting posture of the first drive motor, the measurement and control antenna can be switched between the XY mount form and the AE mount form. The second drive motor is mounted above the structural adapter and has a second fixed part and a second rotating part. The second fixed part is detachably connected to the structural adapter. Both the signal processing and control components and the antenna feed components are driven to rotate by the second rotating part; The first drive motor, the structural adapter, and the second drive motor are interconnected to form an internal wiring channel extending from bottom to top. External cables pass through the internal wiring channel and exit from the inside of the second drive motor, and are electrically connected to the signal processing and control components above.

[0009] The beneficial effects of this invention are as follows: By using a replaceable structural adapter and an adjustable first drive motor, the XY mount configuration and the AE mount configuration can be switched between each other. This allows core components such as the first drive motor, the second drive motor, signal processing and control components, and antenna feed components to be reused in both mount configurations, effectively improving the device's adaptability to different scenarios and reducing overall equipment investment in multiple applications. Simultaneously, the internal wiring channel formed by the first drive motor, the structural adapter, and the second drive motor allows external cables to pass through the structure and connect to the functional components above, preventing cables from being exposed on the outside of the motion axis. This fundamentally eliminates the risk of cable entanglement and wear during operation, improves system reliability, simplifies the external wiring structure, and facilitates rapid on-site setup and dismantling.

[0010] Furthermore, the first drive motor is an external rotor motor, with the output shaft of the first drive motor serving as the first fixed part and the housing of the first drive motor serving as the first rotating part; the second drive motor is an internal rotor motor, with the output shaft of the second drive motor serving as the second rotating part and the housing of the second drive motor serving as the second fixed part.

[0011] Beneficial effects: The configuration of the two motors can adapt to the different installation and transmission requirements of the two shafts, making the overall structural layout more reasonable.

[0012] Furthermore, in the XY frame configuration, the first drive motor is arranged horizontally as the X-axis, and the bottom of the corresponding structural adapter has a lower arc-shaped contact surface to be attached to and fixed to the housing surface of the first drive motor. In the AE bracket configuration, the first drive motor is vertically arranged as the A-axis, and the bottom of the corresponding structural adapter is a flat structure, so as to be attached and fixed to the top of the housing of the first drive motor.

[0013] Beneficial effects: The bottom configuration of the structural adapter is designed to be compatible with the two types of seat frames, which can achieve tight assembly between the structural adapter and the housing of the first drive motor; both structural adapters adopt a detachable fixing method, which can be quickly replaced, and the seat frame type can be conveniently switched while ensuring the structural connection strength.

[0014] Furthermore, in the XY bracket configuration, the outer surface of the housing of the first drive motor is provided with a first annular groove, and the outer surface of the housing of the second drive motor is provided with a second annular groove. The structural adapter is provided with a lower fitting arc surface adapted to the first annular groove and an upper fitting arc surface adapted to the second annular groove. The structural adapter is simultaneously engaged in the first annular groove and the second annular groove. The structural adapter is provided with multiple fixing holes for fasteners to pass through at positions corresponding to the first annular groove and the second annular groove.

[0015] Beneficial effects: By engaging the annular grooves on the surfaces of the two drive motor housings with the fitting arc surfaces on the structural adapter, precise positioning can be achieved during assembly, preventing relative slippage between the structural adapter and the motor housing, thus improving assembly accuracy and structural stability; the setting of fixing holes further ensures the connection strength, allowing the structural adapter to rotate stably with the first rotating part.

[0016] Furthermore, the signal processing and control component includes a baseband module and a servo control module. The baseband module is used to convert the radio frequency signal acquired by the antenna feed component into a digital signal. The servo control module is connected to the first drive motor and the second drive motor. The baseband module and the servo control module are respectively disposed on both sides of the second drive motor, and one of them is fixed relative to the second rotating part, while the other rotates relative to the second fixed part.

[0017] Beneficial effects: Placing the baseband module and servo control module on opposite sides of the second drive motor results in a more balanced layout, which helps optimize the overall weight distribution and improves the stability of the shaft system movement.

[0018] Furthermore, the first rotating part has a first wiring cavity inside, the structural adapter has a through wire hole in the center along the axial direction, the second fixing part has a second wiring cavity inside, and the first wiring cavity, the through wire hole and the second wiring cavity are connected in sequence to form the inner wiring channel.

[0019] Beneficial effects: The cable is entirely within the internal routing channel, avoiding bending, twisting, and wear caused by external movement, thus eliminating the risk of cable tangling; the coaxial through-channel layout makes the overall cable path straight, reducing unnecessary bends and helping to reduce signal transmission loss.

[0020] Furthermore, the second rotating part is provided with a second central hole that penetrates itself, and the second fixed part is provided with a second wiring hole that penetrates itself. The baseband module is provided with a first connector at the position opposite to the second central hole, and the servo control module is provided with a second connector at the position opposite to the second wiring hole. The external cable enters the first wiring cavity from the outside of the first rotating part, passes through the wire hole and the second wiring cavity, and then exits from the second central hole and the second wiring hole respectively, and is electrically connected to the baseband module and the servo control module respectively.

[0021] Beneficial effects: It enables internal cables to be accurately connected to the baseband module and servo control module respectively, with clear circuit partitioning, which facilitates assembly and subsequent maintenance; the cables directly connect to the corresponding connectors from inside the structure, eliminating the need to reserve extra wiring space outside the drive motor, which can further reduce the overall size of the equipment, while ensuring that the cable connection remains stable and reliable during the rotation of the two drive motors.

[0022] Furthermore, a first upper support plate and a second upper support plate are respectively provided on both sides of the second drive motor. The first upper support plate and the second rotating part are connected together with the baseband module. The second upper support plate is connected to the servo control module and rotates with the second fixed part. A transition mounting piece is connected between the first upper support plate and the second upper support plate, and the antenna feed assembly is fixed on the transition mounting piece.

[0023] Beneficial effects: The first upper support plate, the second upper support plate and the transition mounting piece are connected together to form a stable load-bearing frame, which reliably fixes the antenna feed assembly to the rotating side, ensuring that the antenna feed assembly can rotate synchronously with the second rotating part and the antenna pointing state is stable.

[0024] Furthermore, the support assembly includes a tripod and a horizontal mounting base, the horizontal mounting base being fixed to the top of the tripod and having a level sensor inside for leveling; a first drive motor is mounted on the horizontal mounting base.

[0025] Beneficial effects: The tripod has good support stability and portability, and can adapt to the needs of rapid setup in various scenarios; the level sensor integrated inside the horizontal mounting base can provide accurate basis for equipment leveling, ensuring that the base is in a horizontal reference state after setup.

[0026] Furthermore, in the XY bracket configuration, a first lower support plate and a second lower support plate arranged in parallel intervals are installed above the horizontal mounting base. A first drive motor is installed between the first lower support plate and the second lower support plate, and the first fixing part is detachably connected to the first lower support plate, while the first rotating part is rotatably engaged with the second lower support plate. In the AE bracket configuration, the first fixing part is directly and detachably connected to the horizontal mounting base.

[0027] Beneficial effects: The installation structure of the first drive motor is simple, and it is easy to install and disassemble, which is conducive to quickly switching the frame type by matching the corresponding structural adapter. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Specific embodiment 1 of the portable telemetry and control antenna with variable mount provided by the present invention: like Figure 1 , Figure 2 and Figure 9 As shown, the portable telemetry and control antenna with a variable mount includes a support assembly, a first drive motor 1, a replaceable structural adapter 3, a second drive motor 2, a signal processing and control assembly, and an antenna feed assembly 4. The entire device can switch between XY mount and AE mount configurations by replacing the structural adapter 3 with different configurations and adjusting the mounting posture of the first drive motor 1. The core drive, control, and signal processing components, the antenna feed assembly 4, and the support assembly can be reused in both mount configurations.

[0032] Specifically, such as Figure 1 and Figure 8As shown, the support assembly includes a tripod 7 and a horizontal mounting base 8. The horizontal mounting base 8 is fixed to the top of the tripod 7, serving as the mounting base for the upper frame structure. The tripod 7 is a retractable structure, including a central support column 706, a top support base 701, a bottom support base 702, a support arm 703, and channel legs 704. The top support base 701 and the bottom support base 702 are both coaxially fixed to the support column 706. The bottom support base 702 is connected to the bottom end of the support column 706, and the top support base 701 is connected to the middle of the support column 706 and its fixed position is adjustable. Three channel legs 704 are provided, evenly distributed in a circle on the outside of the bottom support base 702. One end of each channel leg 704 is hinged to the bottom support base 702 to allow the channel leg 704 to flip. Three support arms 703 are also provided, evenly distributed in a circle on the outer side of the top support base 701. Each support arm 703 corresponds to a slotted leg 704. The top end of each support arm 703 is hinged to the top support base 701, and the bottom end is hinged to the corresponding slotted leg 704 via an adjusting seat 705. The adjusting seat 705 can slide in a groove in the slotted leg 704, thereby adjusting the fixed position of the bottom end of the support arm 703, thus adjusting the support height and overall stability of the tripod 7. The horizontal mounting base 8 is located at the top of the support column 706 and is connected to the top support base 701. Figure 7 and Figure 13 As shown, the horizontal mounting base 8 is equipped with a horizontal sensor 15, which can provide a leveling reference during equipment installation, ensuring that the base is in a horizontal reference state, and providing a basic guarantee for subsequent motion accuracy.

[0033] like Figure 4 and Figure 5 As shown, the first drive motor 1 is an external rotor motor, having a first fixed part 101 and a first rotating part 102. The output shaft of the first drive motor 1 serves as the first fixed part 101, and the housing of the first drive motor 1 serves as the first rotating part 102. When the first drive motor 1 starts, its housing rotates around the axis of the output shaft. The second drive motor 2 is an internal rotor motor, having a second fixed part 201 and a second rotating part 202. The housing of the second drive motor 2 serves as the second fixed part 201, and the output shaft of the second drive motor 2 serves as the second rotating part 202. When the second drive motor 2 starts, its output shaft rotates around its own axis.

[0034] In this embodiment, the first drive motor 1 is used as the X-axis drive, and the second drive motor 2 is used as the Y-axis drive. The two axes intersect perpendicularly in space, and the entire measurement and control antenna is in the form of an XY mount.

[0035] In the XY frame configuration, such as Figure 7As shown, the first rotating part 102 has a pre-reserved first wiring cavity 103 inside, and the first rotating part 102 also has a first wiring hole 104 communicating with the first wiring cavity 103. The first fixing part 101 has a first central hole 105 penetrating through itself. Both the first central hole 105 and the first wiring hole 104 are coaxial with the output shaft of the first drive motor 1. A first lower support plate 11 and a second lower support plate 12 arranged in parallel are fixedly installed above the horizontal mounting base 8. The first drive motor 1 is horizontally mounted between the first lower support plate 11 and the second lower support plate 12. The first fixing part 101 of the first drive motor 1 is detachably fixed to the first lower support plate 11 by bolts. The first rotating part 102 of the first drive motor 1 is rotatably engaged with the second lower support plate 12 through a bearing structure. The second lower support plate 12 is provided with an aviation plug 14, which is connected to the first wiring hole 104 and the first wiring cavity 103, serving as an interface for external cables to enter the interior.

[0036] like Figure 6 As shown, the second fixing part 201 has a reserved second wiring cavity 203 inside, and the second fixing part 201 also has a second wiring hole 204 communicating with the second wiring cavity 203. The second rotating part 202 has a through second central hole 205 inside, and both the second wiring hole 204 and the second central hole 205 are coaxial with the output shaft of the second drive motor 2. The center of each structural adapter 3 has a through wire hole 302 along the axial direction, which communicates with the first wiring cavity 103 and the second wiring cavity 203. The first wiring cavity 103, the through hole 302 and the second wiring cavity 203 form an internal wiring channel, which extends vertically from bottom to top. The second wiring hole 204 and the second central hole 205 serve as the two upper outlets of the internal wiring channel, respectively, and are connected to different functional modules.

[0037] like Figure 4 As shown, both the first rotating part 102 and the second fixing part 201 are cylindrical structures. The outer surface of the first rotating part 102 is provided with a first annular groove, and the outer surface of the second fixing part 201 is provided with a second annular groove. The axis of the first annular groove and the axis of the second annular groove are perpendicular to each other. The two annular grooves are used to form a positioning fit with the structural adapter 3.

[0038] like Figure 3As shown, the structural adapter 3 is a replaceable component, meaning that the structural adapter 3 is detachably fixed to the first drive motor 1 and the second drive motor 2. The structural adapter 3 has two configurations corresponding to the two frame types. For the XY frame type, the structural adapter 3 has a lower fitting arc surface 303 at the bottom and an upper fitting arc surface 304 at the top. The shape of the lower fitting arc surface 303 matches the first annular groove, and the shape of the upper fitting arc surface 304 matches the second annular groove. Furthermore, the dimensions of the corresponding parts of the structural adapter 3 match the widths of the first and second annular grooves, allowing the structural adapter 3 to be simultaneously positioned within both annular grooves. Figure 4 As shown, at this time, the lower fitting arc surface 303 is tightly fitted with the groove wall of the first annular groove, and the upper fitting arc surface 304 is tightly fitted with the groove wall of the second annular groove. The structural adapter 3 has two sets of fixing holes 301 at positions corresponding to the upper fitting arc surface 304 and the lower fitting arc surface 303, respectively located on the radial sides of the corresponding drive motors. Fasteners can be inserted into the fixing holes 301, thereby connecting the structural adapter 3 to the first rotating part 102 of the first drive motor 1 and the second fixing part 201 of the second drive motor 2 into a single unit.

[0039] like Figure 6 As shown, the signal processing and control components include a baseband module 5 and a servo control module 6, which are respectively located on both sides of the second drive motor 2. The baseband module 5 has a first connector 501 located opposite the second center hole 205 for connecting internal cables. The function of the baseband module 5 is to receive the radio frequency signals acquired by the antenna feed assembly 4 and convert the radio frequency signals into digital signals for external transmission. The servo control module 6 has a second connector 601 located opposite the second wiring hole 204 for connecting internal cables. The servo control module 6 forms a control connection with both the first drive motor 1 and the second drive motor 2, and can output control commands to drive the two drive motors to operate, adjust the pointing angle of the antenna, and achieve continuous target tracking.

[0040] like Figure 5As shown, a first upper support plate 9 and a second upper support plate 10 are respectively provided on both sides of the second drive motor 2. The first upper support plate 9 is detachably connected to the second rotating part 202 by bolts. The baseband module 5 is synchronously fixed to the first upper support plate 9 by bolts and rotates together with the second rotating part 202. The second upper support plate 10 is connected to the servo control module 6 by bolts. The second fixing part 201 of the second drive motor 2 forms a rotational engagement with the second upper support plate 10 through a bearing structure, allowing the second upper support plate 10 to rotate relative to the second fixing part 201. A transition mounting part 13 is connected between the first upper support plate 9 and the second upper support plate 10. The antenna feed assembly 4 is fixedly mounted on the transition mounting part 13 and rotates synchronously with the second rotating part 202, ensuring that the antenna pointing and rotation angle remain consistent. The antenna feed assembly 4 and the baseband module 5 are existing technologies, and their structures will not be described in detail here.

[0041] In the XY frame configuration, combined with Figure 6 It is known that the external power supply and signal cables are connected through the aviation plug 14, first entering the first wiring cavity 103 through the first wiring hole 104, and then passing upward through the wiring hole 302 in the center of the structural adapter 3 to enter the second wiring cavity 203 inside the second drive motor 2. The cables entering the second wiring cavity 203 are divided into two paths: one path exits through the second center hole 205 and is electrically connected to the baseband module 5 through the first connector 501; the other path exits through the second wiring hole 204 and is electrically connected to the servo control module 6 through the second connector 601. The drive cables of the two drive motors themselves can also be connected to the servo control module 6 through the internal wiring channel, with no exposed cables throughout the entire movement segment.

[0042] When the equipment is working, the servo control module 6 controls the operation of the first drive motor 1 and the second drive motor 2 according to the target tracking command, thereby driving the antenna feed assembly 4 to adjust its direction and achieve continuous tracking of the target. When the first drive motor 1 starts, the first rotating part 102 drives the structural adapter 3, the second drive motor 2, the baseband module 5, the servo control module 6, and the antenna feed assembly 4 to rotate around the X-axis, completing the angle adjustment in the X-axis direction. When the second drive motor 2 starts, the second rotating part 202 drives the antenna feed assembly 4 to rotate around the Y-axis through the first upper support plate 9 and the transition mounting part 13, completing the angle adjustment in the Y-axis direction. The dual-axis coordinated movement can achieve a wide range of angle coverage, which is especially suitable for tracking low-orbit satellites and other over-the-head targets, ensuring continuous and uninterrupted signal in the over-the-head area.

[0043] During operation, all power and signal cables are housed within a closed internal cabling channel, moving synchronously with the frame structure. This prevents relative twisting and bending along the rotating shaft, fundamentally avoiding cable tangling and wear, and improving system reliability. The baseband module 5 is positioned above the moving axis. The RF signal output from the antenna feed assembly 4 can be directly connected to the baseband module 5 for analog-to-digital conversion. The converted digital signal can be transmitted externally via a single network cable. Only one power supply cable and one network cable are required externally, significantly simplifying the external wiring structure and facilitating rapid on-site setup and dismantling.

[0044] Specific embodiment 2 of the portable telemetry and control antenna with variable mount provided by the present invention: like Figure 9 and Figure 12 As shown, the difference between this embodiment and the above embodiment 1 is that the first drive motor 1 is driven by the A-axis, the second drive motor 2 is driven by the E-axis, and the entire measurement and control antenna is in the form of an AE mount.

[0045] In the AE mount configuration, the first drive motor 1 is vertically arranged, and the first fixing part 101 of the first drive motor 1 is arranged downward and directly and detachably fixedly connected to the horizontal mounting base 8. The first rotating part 102 does not have a first wiring hole, but only a first wiring cavity 103, and the first wiring cavity 103 extends to the end of the first rotating part 102. An aviation plug 14 is directly fixedly mounted on the side of the first rotating part 102.

[0046] The structure of structural adapter 3 differs from that in the XY frame configuration. In the AE frame configuration, as shown below... Figure 10 and Figure 11 As shown, the bottom of the structural adapter 3 is a planar structure, in the shape of a disc, as... Figure 12 and Figure 13 As shown, the structural adapter 3 is directly placed on the top of the first rotating part 102, covering the first wiring cavity 103. Simultaneously, the structural adapter 3 is fixedly connected to the first rotating part 102 via fasteners. The upper structure of the structural adapter 3 is the same as in the XY bracket type, also using the upper contact arc surface 304 to engage with the second annular groove on the second drive motor 2 and then being fixed with fasteners. The second drive motor 2 rotates together with the structural adapter 3 around the vertical axis.

[0047] External power and signal cables are connected from the aviation plug 14, pass directly through the first wiring cavity 103, then pass upward through the cable guide hole 302 in the center of the structural adapter 3, and enter the second wiring cavity 203 inside the second drive motor 2. The cables entering the second wiring cavity 203 are also divided into two paths: one path exits through the second center hole 205 and is electrically connected to the baseband module 5 through the first connector 501; the other path exits through the second wiring hole 204 and is electrically connected to the servo control module 6 through the second connector 601. The drive cables of the two drive motors themselves can also be connected to the servo control module 6 through the internal wiring channels, with no exposed cables throughout the entire movement segment.

[0048] When the equipment is in operation, when the first drive motor 1 starts, the first rotating part 102 drives the structural adapter 3, the second drive motor 2, the baseband module 5, the servo control module 6, and the antenna feed assembly 4 to rotate as a whole around the vertical A-axis, completing the azimuth angle adjustment. When the second drive motor 2 starts, the second rotating part 202 drives the antenna feed assembly 4 to rotate around the E-axis, completing the elevation angle adjustment, which is suitable for tracking high-speed, low-elevation targets in the initial stage of missiles, rockets, etc.

[0049] In the two embodiments described above, the first drive motor 1 is a combination of an external rotor motor and the second drive motor 2 is an internal rotor motor. In other embodiments, both drive motors may also be internal rotor motors. The housing of the first drive motor 1 serves as the first fixed part 101 connected to the support assembly, and the output shaft serves as the first rotating part 102 driving the structural adapter 3 to rotate. This also enables the dual-axis drive function and the switching between the two frame types.

[0050] In the two embodiments described above, the baseband module 5 and the servo control module 6 are respectively placed on both sides of the second drive motor 2. In other embodiments, the baseband module 5 and the servo control module 6 can also be integrated inside the same sealed housing, fixed as a whole on one side of the second drive motor 2, with a counterweight on the other side to balance the overall weight, which can also realize the functions of radio frequency signal conversion and motor motion control.

[0051] While various embodiments of the invention have been shown and described in this specification, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and essence of the invention.
