[0049] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] Reference Figure 1 , Figure 1 This is a flow chart of the first embodiment of the structural accuracy debugging method of the laser communication terminal of the present application.

[0051] In a first embodiment, the structural accuracy debugging method of the laser communication terminal includes the following steps:

[0052] S10: Obtaining a reading of the autocollimator, wherein the reading is obtained after the autocollimator emits parallel light to one of the working surfaces of the polyhedron;

[0053] It should be noted that the structural accuracy debugging method of the laser communication terminal in this embodiment is applied to a structural accuracy debugging system, and the structural accuracy debugging system includes the laser communication terminal, a polyhedron and an autocollimator.

[0054] like Figure 2 As shown, the laser communication terminal includes a two-dimensional turntable, two signal transceiver modules, a transceiver separation module and an optical antenna module, and the two signal transceiver modules share a transceiver separation module and an optical antenna module.

[0055] Before obtaining the reading of the autocollimator, that is, before precision debugging the structure of the laser communication terminal, it is necessary to first connect the structure to be measured of the laser communication terminal to the polyhedron, and make the rotation center of the structure to be measured coincide with the rotation center of the polyhedron; wherein the polyhedron includes multiple working surfaces; the structure to be measured can be a two-dimensional turntable of the laser communication terminal or a structure in other modules.

[0056] like Figure 3-Figure 4 As shown, during measurement, the axis of rotation of the structure to be measured needs to be perpendicular to the optical axis of the autocollimator; after the autocollimator emits parallel light to one of the working surfaces of the polyhedron, the parallel light is reflected and returns to the autocollimator, and a reading can be obtained from the autocollimator, and the reading can reflect the verticality of the structure to be measured.

[0057] It can be understood that, since the polyhedron coincides with the rotation center of the structure to be measured, the reading can indirectly reflect the verticality of the structure to be measured by reflecting the verticality of the structure to be measured.

[0058] S20: Based on the reading, determining whether the structure to be measured meets a preset accuracy condition;

[0059] Since the reading is used to characterize the verticality of the structure to be measured, it can be determined based on the size of the verticality whether the accuracy of the structure to be measured meets the standard, for example, whether it meets the preset accuracy condition, and the accuracy condition may be that the reading is less than a preset threshold.

[0060] S30: If not satisfied, then based on a preset adjustment method, the rotation center of the structure to be measured is adjusted, and the step of obtaining the reading of the autocollimator is returned. If the reading does not meet the preset condition, then based on a preset adjustment method, the step of adjusting the rotation center of the structure to be measured is performed until it is determined that the structure to be measured meets the preset accuracy condition.

[0061] It can be understood that if the reading is not less than the preset threshold, it is considered that the accuracy of the structure to be measured is insufficient, and it is necessary to adjust the rotation center of the structure to be measured, re-emit parallel light to one of the working surfaces of the polyhedron through the autocollimator, and then re-obtain the reading of the autocollimator until it is determined based on the reading that the structure to be measured meets the preset accuracy condition, and the debugging of the structure to be measured is completed.

[0062] In this embodiment, since the rotation center of the structure to be measured coincides with the rotation center of the polyhedron, the axis of rotation of the structure to be measured is perpendicular to the optical axis of the autocollimator; the reading obtained by obtaining the autocollimator after emitting parallel light to one of the working surfaces of the polyhedron can accurately reflect the accuracy of the structure to be measured; based on the reading, determine whether the structure to be measured meets the preset accuracy condition; if not, adjust the rotation center of the structure to be measured based on the preset adjustment method, and return to the step of obtaining the reading of the autocollimator, and if the reading does not meet the preset condition, adjust the rotation center of the structure to be measured based on the preset adjustment method, until it is determined that the structure to be measured meets the preset accuracy condition. It can be understood that the present application uses an autocollimator and a polyhedron to realize the debugging of the structure to be measured of the laser communication terminal, so that the structure to be measured of the laser communication terminal can meet the preset accuracy condition.

[0063] like Figure 5 As shown, based on the first embodiment, a second embodiment of the structural accuracy debugging method of the laser communication terminal of the present application is proposed. In this embodiment, the step S30 includes:

[0064] A1: The rotation center of the optical axis system is adjusted by adjusting the relative position of the tightening device and the adapter shaft.

[0065] like Figure 6As shown, the structure to be measured includes an optical axis system (the optical axis system is arranged on the two-dimensional turntable), the optical axis system includes an adapter shaft, a fixed sleeve and a bearing, the adapter shaft is installed with an interference fit with the polyhedron, the fixed sleeve is installed in the bearing, the adapter shaft and the fixed sleeve are pre-tightened by a tightening device, and the verticality, flatness, parallelism and roundness processing accuracy of the structural parts of the above-mentioned optical axis system are all within 0.01mm.

[0066] Among them, Figure 7 As shown, the tightening device includes a screw, and the adapter shaft and the fixed sleeve can be pre-tightened by multiple tightening adjustment screws, but an adjustable gap is left. The preset adjustment method includes adjusting the displacement of the screw, and also includes first adjusting the displacement of the screw, and then adjusting the grinding structure of the optical axis system to control the accuracy. Taking into account the deformation effect of the structural parts, when the measurement accuracy is close to the target accuracy, the number of measurements is increased, and the adjustment amplitude and grinding force are reduced to achieve the measurement effect, thereby adjusting the rotation center of the optical axis system and changing the accuracy of the optical axis system.

[0067] It should be noted that the optical axis system includes a pitch axis system and a horizontal axis system. Specifically, the laser communication terminal adjusts the terminal pitch angle through the pitch axis system of the two-dimensional turntable, and adjusts the terminal azimuth through the horizontal axis system of the two-dimensional turntable, so that the optical antenna module transmits a laser signal aimed at a receiving target in the free space, and receives a laser signal emitted by the target in the free space, that is, the accuracy of the pitch axis system and the horizontal axis system directly affects the signal reception accuracy of the laser communication terminal.

[0068] It can be understood that the shaft system structure with bearings as the core inevitably has structural errors accumulated due to factors such as part shape and position errors, assembly position errors, structural clearances, and micro-deformations of low-rigidity components. These structural errors work together to affect the accuracy of the shaft system.

[0069] In order to solve the above problems, this embodiment measures and adjusts the accuracy of the pitch axis system and the horizontal axis system, and requires the error of the pitch mechanical axis system and the horizontal mechanical axis system to reach the μm level, thereby ultimately controlling the signal reception accuracy of the laser communication terminal within the target range.

[0070] Specifically, the implementation method of adjusting the rotation center of the optical axis system by adjusting the relative position of the tightening device and the adapter shaft may be:

[0071] The rotation center of the pitch axis system is adjusted by adjusting the relative position of the tightening device of the pitch axis system and the adapter shaft; or the rotation center of the horizontal axis system is adjusted by adjusting the relative position of the tightening device of the horizontal axis system and the adapter shaft.

[0072] It can be understood that since the pitch axis system and the horizontal axis system respectively affect the pitch angle and azimuth of the terminal, it is necessary to debug the pitch axis system and the horizontal axis system respectively; if the pitch axis system does not meet the preset accuracy conditions, the rotation center of the pitch axis system is adjusted by adjusting the relative position of the tightening device of the pitch axis system and the adapter shaft; if the pitch axis system does not meet the preset accuracy conditions, the rotation center of the horizontal axis system is adjusted by adjusting the relative position of the tightening device of the horizontal axis system and the adapter shaft.

[0073] Specifically, in order to more accurately debug the pitch axis system and the horizontal axis system, the method of obtaining the reading of the autocollimator may be:

[0074] Adjust the working surface of the polyhedron; emit parallel light to the adjusted working surface through the autocollimator; obtain the reading of the autocollimator, and return to the step of adjusting the angle of the polyhedron until a preset stop condition is met.

[0075] It can be understood that since the polyhedron has multiple working surfaces, by adjusting the working surface of the polyhedron, the autocollimator emits parallel light to the adjusted working surface, and a reading of the autocollimator can be obtained; by repeating the above steps, the readings of the autocollimator corresponding to the multiple working surfaces of the polyhedron can be obtained.

[0076] The preset stop condition may be obtaining a preset number of readings.

[0077] Specifically, the implementation method of adjusting the working surface of the polyhedron may be: rotating the adapter shaft in a preset direction by a preset angle to adjust the working surface of the polyhedron.

[0078] It should be noted that the polyhedron has multiple working surfaces, and the angle difference between each working surface is fixed. For example, the angle difference between two adjacent working surfaces can be 15 degrees, that is, the polyhedron is a 24-faceted prism, and the angle difference between two adjacent working surfaces can be 30 degrees, that is, the polyhedron is a 12-faceted prism. Specifically, the number of working surfaces of the polyhedron can be selected based on actual conditions.

[0079] The preset direction can be counterclockwise or clockwise. In the process of adjusting the working surface of the polyhedron, the preset angle is less than 360 degrees, and 360 degrees is an integer multiple of the preset angle; therefore, it can be rotated 15 degrees clockwise, or 30 degrees counterclockwise, etc.; obtain the autocollimator, return to the step of rotating the adapter shaft by the preset angle in the preset direction until the adapter shaft rotates 360 degrees, that is, rotate the adapter shaft once to obtain one reading, and after the adapter shaft rotates 360 degrees, 24 readings can be obtained.

[0080] In order to improve the accuracy of precision judgment, the adapter shaft is rotated by a preset angle in the opposite direction of the preset direction to adjust the working surface of the polyhedron again, and parallel light is emitted to the readjusted working surface through the autocollimator; the reading of the autocollimator corresponding to the readjusted working surface is obtained; and the step of rotating the adapter shaft by a preset angle in the opposite direction of the preset direction is returned to until the preset stop condition is met.

[0081] The preset stop condition may also be that the adapter shaft rotates 360 degrees again or 24 readings are obtained again, etc., which is not limited here.

[0082] Further, the implementation method of determining whether the structure to be tested meets a preset accuracy condition based on the reading may be:

[0083] Based on the readings corresponding to the plurality of adjusted working surfaces, it is determined whether the optical axis system meets the preset accuracy condition.

[0084] For example, after the above steps, the readings corresponding to 48 working surfaces can be obtained, and whether the optical axis system meets the preset accuracy conditions can be determined based on the readings corresponding to the 48 working surfaces. Sufficient data can be used to support the accuracy of the judgment result of whether the optical axis system meets the preset accuracy conditions.

[0085] Specifically, the implementation method of determining whether the optical axis system meets the preset accuracy condition based on the readings corresponding to the multiple adjusted working surfaces may be:

[0086] Determine a first difference between each working surface and the corresponding reading of a preset working surface; determine a second difference between the first difference and a preset angle deviation, wherein the preset angle deviation is the angle deviation between each working surface and the preset working surface; based on the second difference, determine whether the optical axis system meets a preset accuracy condition.

[0087] Among them, the preset working surface can be the first working surface used in the above-mentioned debugging process. By determining the first difference (αi-α0) between the readings corresponding to each subsequently adjusted working surface and the preset working surface, the preset angle deviation can be obtained based on the calibration certificate of the polyhedron, that is, the angle deviation △αi between the i-th surface and the first working surface, and the second difference between the first difference and the preset angle deviation △βi=(αi-α0)-△αi.

[0088] It can be understood that the Δβi is the angular deviation of the optical axis system.

[0089] In this embodiment, when the preset accuracy conditions are not met after multiple measurements are performed using an autocollimator, the rotation center of the optical axis system is adjusted by adjusting the relative position of the tightening device and the adapter shaft. Specifically, the displacement of the screw can be adjusted first, and then the grinding structure can be adjusted to control the accuracy. Considering the deformation effect of the structural parts, when the measurement accuracy is close to the target accuracy, the number of measurements is increased, and the adjustment amplitude and grinding force are reduced to achieve the measurement effect, thereby achieving the purpose of controlling the measurement accuracy and improving the accuracy of precision debugging.

[0121] Alternatively, the rotation center of the horizontal axis system is adjusted by adjusting the relative position of the tightening device of the horizontal axis system and the adapter shaft.

[0122] In this embodiment, since the rotation center of the structure to be measured coincides with the rotation center of the polyhedron, the rotation axis of the structure to be measured is perpendicular to the optical axis of the autocollimator; the accuracy of the structure to be measured can be accurately reflected by obtaining the reading obtained by the autocollimator after emitting parallel light to one of the working surfaces of the polyhedron; based on the reading, determine whether the structure to be measured meets the preset accuracy condition; if not, adjust the rotation center of the structure to be measured based on the preset adjustment method, and return to the step of obtaining the reading of the autocollimator, and if the reading does not meet the preset condition, adjust the rotation center of the structure to be measured based on the preset adjustment method, until it is determined that the structure to be measured meets the preset accuracy condition. It can be understood that the present application adopts an autocollimator and a polyhedron to realize the debugging of the structure to be measured of the laser communication terminal, so that the structure to be measured of the laser communication terminal can meet the preset accuracy condition.

[0123] In addition, the embodiment of the present application further proposes a computer-readable storage medium, on which a structure accuracy debugging program of a laser communication terminal is stored. When the structure accuracy debugging program of the laser communication terminal is executed by a processor, the following operations are implemented:

If the reading does not meet the preset condition, then based on the preset adjustment method, the step of adjusting the rotation center of the structure to be measured is performed until it is determined that the structure to be measured meets the preset accuracy condition.

[0127] In this embodiment, since the rotation center of the structure to be measured coincides with the rotation center of the polyhedron, the rotation axis of the structure to be measured is perpendicular to the optical axis of the autocollimator; the accuracy of the structure to be measured can be accurately reflected by obtaining the reading obtained by the autocollimator after emitting parallel light to one of the working surfaces of the polyhedron; based on the reading, determine whether the structure to be measured meets the preset accuracy condition; if not, adjust the rotation center of the structure to be measured based on the preset adjustment method, and return to the step of obtaining the reading of the autocollimator, and if the reading does not meet the preset condition, adjust the rotation center of the structure to be measured based on the preset adjustment method, until it is determined that the structure to be measured meets the preset accuracy condition.
