Description

Technical Field

[0001] This utility model relates to the field of astronomical observation equipment technology, and more specifically, to a single-path multi-star simulation structure. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] A single-path multi-star simulator is a high-precision optical simulation device used for ground testing. Its main function is to simulate the distribution of stars or specific point targets in the night sky, providing a performance verification environment for precision tracking and positioning systems (precision tracking subsystems) such as astronomical cameras and star sensors. It reconstructs a realistic observation area in the laboratory, thus enabling the testing and calibration of core functions such as target extraction and astronomical positioning without the need for actual field observation experiments, significantly improving R&D efficiency and testing convenience.

[0004] Traditional single-channel multi-satellite simulators typically consist of a support, a lens barrel, a built-in star point plate, and a light source. In actual use, the light emitted by the light source passes through a star point plate engraved with simulated star point patterns, and is then collimated by the lens assembly before being emitted, forming a near-infinite horizontal star beam for the device under test to collect and identify. Traditional lens barrels are often made of materials such as steel or aluminum alloy to ensure structural strength, and the star point plate is fixedly installed inside the lens barrel.

[0005] However, the above-mentioned technologies have the following drawbacks: due to the fixed setting of the star point plate, when it is necessary to change different star charts or target scene simulations, it is often necessary to disassemble and reassemble the entire equipment in a cumbersome manner. This not only leads to low operating efficiency, but also introduces mechanical errors during repeated disassembly and reassembly, which in turn affects the simulation accuracy. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to provide a single-channel multi-satellite simulation structure that can effectively improve the convenience of structural adjustments, while simultaneously increasing operational efficiency, reducing mechanical errors generated during repeated disassembly and assembly, and ensuring accurate simulation.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A single-path multi-satellite simulation structure includes a support and a lens barrel. The lens barrel includes a first sub-tube and a second sub-tube, which are coaxially arranged and connected to each other. A lens assembly is disposed on the side of the first sub-tube away from the second sub-tube, and the lens assembly is detachably connected to the first sub-tube. A plate holder is disposed on the side of the second sub-tube away from the first sub-tube, and the plate holder is detachably connected to the second sub-tube. A mounting base is disposed on the side of the plate holder away from the second sub-tube, and a light source is disposed on the mounting base. Plates are inserted into the plate holder.

[0009] In some possible embodiments, an abutment gasket is provided between the insert holder and the second sub-tube. One side of the abutment gasket abuts against the second sub-tube, and the other side abuts against the insert holder. The insert holder has a first mounting hole, and the abutment gasket has a through second mounting hole. A mounting bolt slides through the first mounting hole and slides through the second mounting hole. The second sub-tube has a third mounting hole for inserting the mounting bolt. The top of the insert holder has an insertion hole, and the insert is slidably inserted into the insertion hole.

[0010] In some possible embodiments, the insert holder includes a connecting portion and a fixing portion. The connecting portion abuts against an abutting gasket. A first mounting hole is formed on the connecting portion. The fixing portion is located on the side of the connecting portion away from the abutting gasket. The fixing portion and the connecting portion are detachably connected. An insertion hole is formed on the top of the connecting portion. A slot is formed on the bottom of the connecting portion for inserting the insert. The slot is provided corresponding to the insertion hole.

[0011] In some possible embodiments, a buffer groove is provided on the side of the fixing part near the connecting part.

[0012] In some possible embodiments, the insert includes a mounting portion and a star plate. The mounting portion is slidably inserted into the insertion hole. The mounting portion has a mounting groove. The star plate is disposed in the mounting groove. The mounting portion is provided with a fixing member for limiting the position of the star plate in the mounting groove.

[0013] In some possible embodiments, the fastener is configured as a fixed frame, the shape and size of the fastener are adapted to the opening of the mounting groove, the fastener is detachably disposed in the mounting groove, one side of the star plate abuts against the inner bottom wall of the mounting groove, and the other side abuts against the fastener, a fixed ear is fixedly disposed at the bottom of the fastener, and a fixed groove is provided on the mounting part for the fixed ear to be inserted.

[0014] In some possible embodiments, the bottom of the mounting part is provided with a slope, which is provided on both sides of the bottom of the mounting part along the length of the lens barrel, and the two slopes are set at an acute angle in the direction of bottom convergence and top opening.

[0015] In some possible embodiments, a handle is provided on the top of the mounting part, and a handle groove is provided on the handle.

[0016] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

In actual use, users can realize the simulation of different star charts or target scenes by replacing the plug, without disassembling the lens barrel or adjusting the main structure of the optical path. This greatly shortens the equipment reconfiguration time and avoids mechanical errors caused by frequent disassembly and assembly, ensuring the consistency of simulation accuracy. It is suitable for the research and development and verification stage that requires frequent switching of test scenarios.

[0018] 2. The lens barrel adopts a split design, which can effectively facilitate the handling, installation and debugging of the equipment. The split structure also facilitates the independent processing, assembly and subsequent maintenance of each component, significantly improving the convenience of production and use.

[0019] 3. Through the cooperation of the insert, the socket and the slot, it is ensured that the reset can be accurately reset every time it is inserted or removed. A buffer groove is set between the connecting part and the fixing part, and the abutment gasket also plays the role of stress buffering and error compensation. This can effectively reduce the impact of assembly stress and small deformation on the optical path, ensure the high repeatability of the star board, and thus improve the reliability and accuracy of analog output.

[0020] 4. The top of the insert is equipped with a handle with a hand slot, which facilitates the user's insertion and removal operations. The angle and position of the telescope tube can be finely adjusted through the support adjustment, which facilitates quick alignment with the system under test. This significantly improves the user experience in actual use and the application adaptability of the entire single-channel multi-satellite simulation system. Attached Figure Description
