Description

Technical Field

[0001] The present application relates to the field of laser communications, and in particular to a multi-dimensionally adjustable ground scrambling test system for laser communication terminals. Background Art

[0002] Currently, the commercial aerospace industry has become a strategically developed global industry. Satellite communications, one of the industry's primary application areas, is experiencing exponential growth. Laser communications are gradually emerging in the satellite communications arena. Intelligent laser communication terminals and mass production are inevitable trends. Shortening debugging and testing cycles is one of the keys to overcoming the high costs and long construction periods associated with mass production of satellite laser communications.

[0003] Pointing, Acquisition, and Tracking (PAT) technology is a key element in achieving space laser communications. In space laser communications, the long distances and high relative velocities between satellites are a major challenge, as is the interference from beam jitter caused by satellite vibrations. Therefore, controlling PAT in space laser communications is challenging. The ground-based test equivalent system simulates changes in satellite orbit, attitude, vibration, and beam state on the ground, tailored to the actual operating environment of laser terminal PAT control. This system supports equivalent testing of inter-satellite and satellite-to-ground laser links.

[0004] The existing ground equivalent test system mainly faces the following difficulties and challenges: 1) The test system uses a large volume of space, which not only has high requirements for the site, but is also not conducive to improving test efficiency; 2) The existing test system has different test systems for different dimensional scrambling, resulting in high costs; 3) The existing test system equipment is expensive, complex in structure, and has a long production cycle, making it impossible to achieve mass production. Summary of the Invention

[0005] In order to solve the problems of existing ground equivalent test systems such as large space usage, high site requirements, high cost, and inability to achieve mass production, the present application provides a multi-dimensional adjustable laser communication terminal ground scrambling test system.

[0006] The present application provides a multi-dimensional adjustable laser communication terminal ground scrambling test system that adopts the following technical solutions:

[0007] A multi-dimensional adjustable laser communication terminal ground scrambling test system includes a laser communication terminal, a collimator, a light adjustment mechanism, a first-direction scrambling turntable, a second-direction scrambling swing table and a swing table contour tooling, wherein the first direction and the second direction do not overlap; the second-direction scrambling swing table and the swing table contour tooling have the same thickness and one of them can be installed selectively, when the second-direction scrambling swing table is installed, the second-direction scrambling swing table is arranged on the first-direction scrambling turntable, and the light adjustment mechanism is arranged on the second-direction scrambling swing table; when the swing table contour tooling is installed, the swing table contour tooling is arranged on the first-direction scrambling turntable, and the light adjustment mechanism is arranged on the swing table contour tooling; the laser communication terminal is installed on the light adjustment mechanism, the collimator is arranged on one side of the first-direction scrambling turntable, the first-direction scrambling turntable is used to drive the laser communication terminal to rotate in the first direction, the second-direction scrambling swing table is used to drive the laser communication terminal to swing in the second direction, and the light adjustment mechanism is used to adjust the alignment of the light beams of the laser communication terminal and the collimator.

[0008] By adopting the above technical solution, when the second-direction scrambling oscillating table is replaced with an oscillating table and other height fixtures, the laser communication terminal, collimator, alignment mechanism, first-direction scrambling turntable, and oscillating table and other height fixtures form a one-dimensional terminal scrambling subsystem. During testing, the first-direction scrambling turntable drives the laser communication terminal to rotate about the Z axis, thereby achieving one-dimensional scrambling of the laser communication terminal in one direction. When the oscillating table and other height fixtures are replaced with the second-direction scrambling oscillating table and other height fixtures, the laser communication terminal, collimator, alignment mechanism, first-direction scrambling turntable, and second-direction scrambling oscillating table form a two-dimensional terminal scrambling subsystem. During testing, the first-direction scrambling turntable drives the laser communication terminal to rotate about the Z axis, while the second-direction scrambling oscillating table drives the laser communication terminal to swing along the Y axis, thereby achieving two-dimensional scrambling of the laser communication terminal in two directions. By replacing the height fixtures, multi-dimensional scrambling from one dimension to two dimensions can be achieved simultaneously, significantly reducing the size and weight of the terminal scrambling system, lowering the site requirements for the terminal scrambling system, and reducing production costs, facilitating mass production and testing.

[0009] As a further improvement of the above technical solution, a counterweight is provided on the first-direction scrambling turntable so that the center of gravity of the load on the first-direction scrambling turntable coincides with the rotation center of the first-direction scrambling turntable.

[0010] By adopting the above technical solution, the counterweight is used to compensate for the defect that the center of the rotating table on the laser communication terminal needs to coincide with the rotation center of the first direction scrambling turntable, resulting in the center of the laser communication terminal, the light adjustment mechanism, the first direction scrambling turntable, the swing table and other high tooling, the vibration table and other high tooling (that is, the load on the first direction scrambling turntable) are not on the rotation center of the first direction scrambling turntable.

[0011] As a further improvement to the above technical solution, it also includes a third-direction scrambling vibration table and a vibration table contour tooling, both of which have the same thickness and are installed selectively. When the vibration table contour tooling and the swing table contour tooling are installed, the vibration table contour tooling is installed on the first-direction scrambling turntable, the swing table contour tooling is installed on the vibration table contour tooling, and the light adjustment mechanism is installed on the swing table contour tooling; when the third-direction scrambling vibration table and the second-direction scrambling swing table are installed, the third-direction scrambling vibration table is installed on the first-direction scrambling turntable, the second-direction scrambling swing table is installed on the third-direction scrambling vibration table, and the light adjustment mechanism is installed on the second-direction scrambling swing table; the third-direction scrambling vibration table is used to drive the laser communication terminal to vibrate along a third direction, and the third direction does not overlap with the first direction and the second direction. The first direction, the second direction, and the third direction form a three-axis coordinate system.

[0012] By adopting the above technical solution, a third-direction scrambling vibration table is added on the basis of one-dimensional and two-dimensional. The first-direction scrambling turntable, the second-direction scrambling swing table and the third-direction scrambling vibration table constitute a three-dimensional terminal scrambling subsystem. The first-direction scrambling turntable drives the laser communication terminal to rotate around the Z-axis, the second-direction scrambling swing table drives the laser communication terminal to swing along the Y-axis, and the third-direction scrambling vibration table drives the laser communication terminal to vibrate slightly along the Z-axis, thereby achieving effective disturbance in the Z-axis direction and realizing three-dimensional scrambling of the laser communication terminal.

[0013] As a further improvement of the above technical solution, a turntable adapter plate is provided on the first-direction scrambling turntable, and the third-direction scrambling vibration table or vibration table or other high-level tooling is provided on the turntable adapter plate.

[0014] By adopting the above technical solution, a turntable adapter plate is set on the top of the first direction scrambling turntable, which can increase the installation area, thereby facilitating the installation of the laser communication terminal, the light adjustment mechanism, the second direction scrambling swing table, and various equal height tooling.

[0015] As a further improvement of the above technical solution, when the third-direction scrambling vibration table is installed, a transfer plate is provided on the third-direction scrambling vibration table, and the second-direction scrambling swing table is provided on the transfer plate.

[0016] By adopting the above technical solution, the transfer platform is used to connect the second direction scrambling swing platform and the third direction scrambling vibration platform to ensure the stability of the installation of the second direction scrambling swing platform.

[0017] As a further improvement of the above technical solution, a counterweight is provided on the transfer platform so that the center of gravity of the load on the transfer platform coincides with the rotation center of the first direction scrambling turntable.

[0018] By adopting the above technical solution, the load torque of the scrambling turntable in the first direction can be reduced, thereby ensuring its rotational stability.

[0019] As a further improvement of the above technical solution, a terminal adapter plate is provided between the laser communication terminal and the light adjustment mechanism.

[0020] By adopting the above technical solution, the terminal adapter plate provides support for the installation of the laser communication terminal, ensuring that it can be stably installed on the light adjustment mechanism.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This multi-dimensional adjustable terminal scrambling system can simultaneously achieve multi-dimensional scrambling from one dimension to three dimensions by replacing some tooling components, greatly reducing the size and weight of the terminal scrambling system, lowering the requirements for the terminal scrambling system's use site, reducing costs, and facilitating mass production and testing.

[0023] 2. The multi-dimensional adjustable terminal scrambling system adopts a one-dimensional turntable plus a micro-vibration table control method, eliminating the two-dimensional turntable control part in the existing terminal scrambling system, greatly reducing the requirements for program control, shortening the production cycle and cost of test system components, and improving the test efficiency of the test system.

[0024] 3. The contour tooling used for replacing the structure and the adapter plates used for the adapter connection in the multi-dimensional adjustable terminal scrambling system are simple in structure and low in weight, which improves the production efficiency of the test system and greatly reduces the production cost of the test system, which is conducive to the mass production of the test system.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The directional words such as "up", "down", "left", "right", "front", and "back" in this application only represent the relative positions in the figure. They are for the convenience of describing this application and do not represent the absolute position of the product and should not be regarded as limiting this application.

[0033] Example 1

[0034] The embodiment of the present application discloses a multi-dimensional adjustable laser communication terminal ground scrambling test system.

[0035] like Figures 1 to 3 As shown, the multi-dimensional adjustable laser communication terminal ground scrambling test system of this embodiment includes a laser communication terminal 1, a collimator 2, an alignment adjustment mechanism 3, a first-direction scrambling turntable 4, a second-direction scrambling swing table 5, a swing table height fixture 6, a third-direction scrambling vibration table 8, and a vibration table height fixture 9. In this embodiment, the first, second, and third directions are represented by a three-axis coordinate system, namely, the Z-axis, the Y-axis, and the X-axis.

[0036] The above structures are assembled and installed so that the multi-dimensional adjustable laser communication terminal ground scrambling test system forms a one-dimensional terminal scrambling subsystem, a two-dimensional terminal scrambling subsystem, and a three-dimensional terminal scrambling subsystem.

[0037] like Figure 1 As shown, specifically, the one-dimensional terminal scrambling subsystem mainly includes: a laser communication terminal 1, a parallel light pipe 2, a light adjustment mechanism 3, a first direction scrambling turntable 4, a swing table and contour tooling 6, and a vibration table and contour tooling 9.

[0038] The first-direction scrambling turntable 4 is mounted on the optical test platform via a base plate 13, to which a turntable adapter plate 10 is fixed. The vibration table contour tooling 9 is mounted on the turntable adapter plate 10, the swing table contour tooling 6 is mounted on the vibration table contour tooling 9, and the optical adjustment mechanism 3 is mounted on the swing table contour tooling 6. The laser communication terminal 1 is connected to the optical adjustment mechanism 3 via a terminal adapter plate 12. The collimator 2 is located on one side of the first-direction scrambling turntable 4 and is mounted on a base of the optical test platform.

[0039] During the test, the collimator 2 will emit a light beam, and the reference mirror position of the laser communication terminal 1 is adjusted by the light adjustment mechanism 3 to align it with the light beam of the collimator 2 (shown as Figure 1 The collimator 2 is a slender tubular structure between the collimator 2 and the laser communication terminal 1. The first-direction scrambling turntable 4 rotates the laser communication terminal 1 about the Z axis, changing the position of the light spot received by the laser communication terminal 1. This achieves one-dimensional scrambling of the laser communication terminal 1 in one direction. The collimator 2 simulates the satellite laser communication signal. It produces a highly collimated beam, simulating the laser signals used in actual inter-satellite communications and ensuring the realism of the test environment. The first-direction scrambling turntable 4 rotates the laser communication terminal 1 about the Z axis, simulating the satellite's attitude changes in space.

[0040] It should be noted that, since the laser communication terminal 1 has a rotating table, the center of this rotating table needs to coincide with the rotation center of the first direction scrambling turntable 4. This will cause the centers of the laser communication terminal 1, the light adjustment mechanism 3, the first direction scrambling turntable 4, the swing table and other high tooling 6, the vibration table and other high tooling 9 (that is, the load on the first direction scrambling turntable 4) to not be on the rotation center of the first direction scrambling turntable 4, resulting in the center of gravity of the load on the first direction scrambling turntable 4 not being on the rotation center of the first direction scrambling turntable 4. Therefore, a counterweight needs to be provided. In this embodiment, a counterweight 7 is provided on the turntable adapter plate 10 of the first direction scrambling turntable 4 to make the center of gravity of the load on the first direction scrambling turntable 4 coincide with the rotation center of the first direction scrambling turntable 4, thereby reducing the load torque and ensuring rotational stability.

[0041] like Figure 2 As shown, specifically, the two-dimensional terminal scrambling subsystem mainly includes: a laser communication terminal 1, a parallel light pipe 2, a light adjustment mechanism 3, a first direction scrambling turntable 4, a second direction scrambling swing table 5 and a vibration table and other high-level tooling 9.

[0042] The first-direction scrambling turntable 4 is mounted on the optical testing platform via a base plate 13, onto which a turntable adapter plate 10 is fixed. The vibration table contour tooling 9 is mounted on the turntable adapter plate 10. The second-direction scrambling swing table 5 is mounted on the vibration table contour tooling 9. The light adjustment mechanism 3 is mounted on the second-direction scrambling swing table 5. The laser communication terminal 1 is connected to the light adjustment mechanism 3 via a terminal adapter plate 12. The installation method of the collimator 2 is the same as that in the one-dimensional terminal scrambling subsystem. The second-direction scrambling swing table 5 and the swing table contour tooling 6 have the same thickness. Therefore, after the second-direction scrambling swing table 5 replaces the swing table contour tooling 6, the height of the laser communication terminal 1 in the two-dimensional terminal scrambling subsystem is consistent with the height of the laser communication terminal 1 in the one-dimensional terminal scrambling subsystem, and the light alignment accuracy between the laser communication terminal 1 and the collimator 2 is not affected. Similarly, the two-dimensional terminal scrambling subsystem also needs to add a counterweight 7, and the installation method of the counterweight 7 is the same as that in the one-dimensional terminal scrambling subsystem.

[0043] During testing, collimator 2 emits a light beam, and the alignment mechanism 3 adjusts the position of the reference mirror of laser communication terminal 1 to align it with the collimator 2's beam. The first-direction scrambling turntable 4 rotates laser communication terminal 1 about the Z axis, while the second-direction scrambling swing stage 5 swings laser communication terminal 1 along the Y axis. This changes the position of the light spot received by laser communication terminal 1, thus achieving two-dimensional scrambling of laser communication terminal 1 in both directions.

[0044] like Figure 3 As shown, specifically, the three-dimensional terminal scrambling subsystem mainly includes: a laser communication terminal 1, a collimator 2, a light adjustment mechanism 3, a first direction scrambling turntable 4, a second direction scrambling swing table 5 and a third direction scrambling vibration table 8.

[0045] The first-direction scrambling turntable 4 is mounted on the optical test platform via a base plate 13, onto which a turntable adapter plate 10 is fixed. The third-direction scrambling vibration table 8 is disposed on the turntable adapter plate 10. A transfer plate 11 is disposed on the third-direction scrambling vibration table 8. The second-direction scrambling swing table 5 is disposed on the transfer plate 11. The alignment adjustment mechanism 3 is disposed on the second-direction scrambling swing table 5. The laser communication terminal 1 is connected to the alignment adjustment mechanism 3 via a terminal adapter plate 12. Similarly, the total thickness of the third-direction scrambling vibration table 8 and the transfer plate 11 thereon is the same as the thickness of the vibration table contour tooling 9. Therefore, after the third-direction scrambling vibration table 8 replaces the vibration table contour tooling 9, the height of the laser communication terminal 1 in the three-dimensional terminal scrambling subsystem is consistent with the height of the laser communication terminal 1 in the two-dimensional terminal scrambling subsystem, and does not affect the alignment accuracy of the laser communication terminal 1 and the parallel light tube 2. Similarly, the three-dimensional terminal scrambling subsystem also needs to add a counterweight 7. Due to the setting of the third-direction scrambling vibration table 8, the counterweight 7 is installed on the transfer plate 11 of the third-direction scrambling vibration table 8.

[0046] During testing, collimator 2 emits a beam. The alignment mechanism 3 adjusts the position of the reference mirror of laser communication terminal 1 to align it with the collimator 2's beam. A first-direction scrambling turntable 4 rotates laser communication terminal 1 about the Z axis, a second-direction scrambling swing table 5 oscillates laser communication terminal 1 along the Y axis, and a third-direction scrambling vibration table 8 slightly vibrates laser communication terminal 1 along the Z axis, achieving effective perturbation in the Z direction. This three-dimensional terminal scrambling subsystem implements three-dimensional scrambling of laser communication terminal 1.

[0047] In this embodiment, the first-direction scrambling turntable 4 is a conventional turntable structure, the second-direction scrambling oscillating table 5 is a conventional curved oscillating table structure, and the third-direction scrambling vibrating table 8 is a micro-vibrating table structure. The alignment adjustment mechanism 3 is identical to the second-direction scrambling oscillating table 5 in structure, a conventional curved oscillating table structure, and both are manually adjustable. The alignment adjustment mechanism 3 is cross-connected to the second-direction scrambling oscillating table 5 at a 90° angle. The alignment adjustment mechanism 3 controls the rotation and oscillation of the laser communication terminal 1 along the X-axis, while the second-direction scrambling oscillating table 5 controls the rotation and oscillation of the laser communication terminal 1 along the Y-axis.

[0048] Example 2

[0049] The multi-dimensional adjustable laser communication terminal ground scrambling test system of the present embodiment differs from that of Example 1 in that:

[0050] The test system of this embodiment does not include the third-dimensional scrambling vibration table 8 and the vibration table and other high-level tooling 9, and only has a one-dimensional terminal scrambling subsystem and a two-dimensional terminal scrambling subsystem.

[0051] like Figure 4 As shown, specifically, the one-dimensional terminal scrambling subsystem includes a laser communication terminal 1, a collimator 2, an alignment adjustment mechanism 3, a first direction scrambling turntable 4 and a swing table and iso-height tooling 6.

[0052] The first-direction scrambling turntable 4 is mounted on the optical test platform via a base plate 13, onto which a turntable adapter plate 10 is fixed. The swing table contour tooling 6 is mounted on the turntable adapter plate 10, and the light adjustment mechanism 3 is mounted on the swing table contour tooling 6. The laser communication terminal 1 is connected to the light adjustment mechanism 3 via a terminal adapter plate 12. The collimator 2 is located on one side of the first-direction scrambling turntable 4 and is mounted on a base of the optical test platform. Since this embodiment does not include the third-direction scrambling vibration table 8, the vibration table contour tooling 9 is not provided. The counterweight 7 is mounted on the turntable adapter plate 10.

[0053] During testing, collimator 2 emits a light beam, and the alignment mechanism 3 adjusts the position of the reference mirror of laser communication terminal 1 to align it with the beam of collimator 2. The first-direction scrambling turntable 4 rotates laser communication terminal 1 around the Z axis, causing the position of the light spot received by laser communication terminal 1 to change, thereby achieving one-dimensional scrambling in one direction of laser communication terminal 1.

[0054] like Figure 5 As shown, the two-dimensional terminal scrambling subsystem includes a laser communication terminal 1, a collimator 2, a light adjustment mechanism 3, a first direction scrambling turntable 4 and a second direction scrambling swing table 5.

[0055] The first-direction scrambling turntable 4 is mounted on the optical test platform via a base plate 13, to which a turntable adapter plate 10 is fixed. The second-direction scrambling swing table 5 is mounted on the turntable adapter plate 10. The alignment adjustment mechanism 3 is mounted on the second-direction scrambling swing table 5. The laser communication terminal 1 is connected to the alignment adjustment mechanism 3 via a terminal adapter plate 12. The collimator 2 is mounted in the same manner as in the one-dimensional terminal scrambling subsystem.

[0056] During testing, collimator 2 emits a light beam, and the alignment mechanism 3 adjusts the position of the reference mirror of laser communication terminal 1 to align it with the collimator 2's beam. The first-direction scrambling turntable 4 rotates laser communication terminal 1 about the Z axis, while the second-direction scrambling swing stage 5 swings laser communication terminal 1 along the Y axis. This changes the position of the light spot received by laser communication terminal 1, thus achieving two-dimensional scrambling of laser communication terminal 1 in both directions.

[0057] It should be noted that, in addition to the above embodiments 1 and 2, there may be multiple combinations in other embodiments. For example, the second-direction scrambling swing table 5 in embodiment 2 may be replaced with a third-direction scrambling vibration table 8 to achieve one-dimensional or two-dimensional scrambling.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
