Description

Technical Field

[0001] The utility model relates to the field of calibration measurement, in particular to a device for quickly calibrating the azimuth and altitude of shipborne artillery and land-based artillery. Background Art

[0002] During the calibration and measurement process of shipborne and land-based artillery, the azimuth, altitude, and pointing of the relevant equipment need to be unified with the ship's or land-based reference azimuth and altitude. The current calibration and measurement equipment uses the theodolite and the astroscope on the calibration equipment to aim at the stars at the same time, unifying the pointing of the equipment with the azimuth and altitude reference of the theodolite, and then aiming the theodolite at the ship's or land-based baseline to achieve the unification of the equipment's and the ship's or land-based reference azimuth and altitude. However, due to structural problems with the calibration equipment, the following issues arise during use: 1) The process of aligning the theodolite with the ship's datum plane is inefficient, requires a long adjustment time, and requires high technical skills. 2) When aiming the theodolite and the equipment at stars, the selection of stars generally relies on human visual discrimination in the sky, resulting in suboptimal altitude angles, brightness, and other aspects of the selected stars. Furthermore, when the calibration time is too long and the Earth rotates during this period, the selected stars cannot be effectively utilized to complete the entire calibration measurement process. 3) When using the theodolite to aim at stars, the surveyor needs to continuously observe the instrument for aiming and tracking, which consumes a lot of surveyor time and energy and prevents the theodolite from automatically tracking and aiming the stars. 4) When aiming at stars using the astronomical scope on the equipment, the equipment needs to be continuously rotated to keep the equipment and the stars aligned, which is time-consuming and labor-intensive, making it difficult to achieve a rough aiming of the astronomical scope at the star and a precise aiming angle. 5) Data synchronization between the theodolite and the astronomical scope requires voice commands, which is inefficient. 6) Data processing requires on-site calculations, which is inefficient and has poor accuracy and reliability. Therefore, improvements and innovations in calibration equipment are imperative. Summary of the Invention

[0003] In view of the above situation, in order to solve the defects of the existing technology, the purpose of the present invention is to provide a rapid calibration equipment for the azimuth and altitude of shipborne artillery and land-based artillery, which can effectively solve the problems of difficult operation, low work efficiency, poor aiming angle accuracy, and poor accuracy and reliability of the original equipment.

[0004] The technical solution provided by the utility model includes a hollow shaft, a camera, a multi-channel interface communication power supply controller and a tablet computer.

The center of the hollow shaft and the center of the lens at the front end of the camera are on the same axis to form an aiming structure. The camera data interface on the camera is connected to the camera communication interface of the multi-channel interface communication power supply controller via a transmission line. The multi-channel interface communication power supply controller is connected to the tablet computer via a network data interface by wire or wireless.

[0005] The utility model has a simple structure, is novel and unique, can adopt hollow shafts of different sizes according to different gun calibers and can be inserted into the gun barrel.
