Description

Static-to-static optical direct aiming system based on gun bore

technical field

The invention relates to the technical field of optical imaging, in particular to a static-to-static optical direct sighting system based on the barrel of a tank artillery.

Background technique

As a direct-pointing weapon, tank guns are mainly used to penetrate armor and destroy enemy firearms and fortifications. Due to the gravitational effect of the earth, the shells will fall down after being fired, so the artillery generally shoots at an elevation angle, but the effective range of the anti-tank is mostly about 2 kilometers. The target is large, so tank guns are mostly aimed directly. Shooting where the ballistic height on the aiming line does not exceed the target height throughout the range is called direct shooting, and this distance is also called direct shooting distance. The size of the direct shot distance depends on the height of the target and the low extension of the ballistic. Because tank guns do not pursue range, but anti-armor, they pursue fast initial velocity (mostly smoothbore guns, such as muzzle velocity can reach about 1700 m/s), low ballistic extension, and large tank targets, so at this time In terms of the corresponding distance, the target can be hit directly by aiming at the center of the target with the aiming mark (for example, when shooting a standing target at a distance of 1500 meters, the projectile spread is only 0.3 meters × 0.3 meters), and the corresponding distance is the direct shooting distance. Also because it seems that the cannon flies straight to the target after ejecting from the chamber, it is also called direct aiming.

The firing of tank guns must be controlled by the sighting and sighting system. The sighting and sighting system provides the commander with battlefield situation information and the shooter with a channel to observe, search and aim at the target. Its advantages and disadvantages directly affect the combat capability of tanks and armored vehicles. Modern sighting and sighting systems are so advanced that they have the capability of moving-to-moving shooting and aiming. But static-to-static shooting is also a common situation, especially when the sighting system fails, how to accurately hit the target is a very important and practical action. For example, in the two multinational tank competitions held in Russia, including the participation of our army, there were situations where static-to-static shots failed due to problems with the sighting system.

For general light weapons: such as automatic rifles, since the front sight and the notch are directly on the axis of the barrel, when there is a problem with the installed optical sighting system, the mechanical aiming system of the front sight and the notch can be used to aim and shoot. The barrel of the tank and the aiming system are separated. Before leaving the factory, they are adjusted so that the aiming line is parallel to the axis of the artillery. After delivery to the troops, regular corrections are required. Once there is a problem with the aiming system, such as vibration or wiring problems, the axis of the barrel of the gun is not aligned with the axis of the gun. When there is an error in the relationship between the aiming systems, the optical system is damaged, the electronic components are damaged, etc., it will not be possible to achieve aiming or accurately hit the target. And the present invention will be able to solve this problem preferably, realize static to static accurate aiming and shooting under the special working condition.

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Referring to Fig. 1 to Fig. 5, a static-to-static optical direct sight system based on a gun bore provided by the present invention includes an optical lens group 9, a CMOS image sensor 16, a laser range finder 8, a lens holder 10, and signal transmission lines 5, 19 And the display screen 6, the top of the laser range finder 8 is provided with a laser source transmitter 7.

The CMOS image sensor 16 is connected to the display screen 6 through the signal transmission line 5 , and the optical lens group 9 and the laser rangefinder 8 are connected to the display screen 6 through the signal transmission line 19 .

As shown in FIG. 1 , the external structure of the system includes a gun barrel 1 , a gun bore 2 , a turret 4 , an optical system 3 , a signal transmission line 5 and a display screen 6 .

As shown in Figures 2 and 3, the optical system includes a lens assembly, a cylinder body 11, a lens holder 10, a cylinder cover 18, a handle 15 and a knob 14, and the lens assembly includes an optical lens group 9, a CMOS image sensor 16, a laser range finder 8 .

The overall shape of the optical system is consistent with that of the shell casing, which can be determined according to the specific conditions of the structure of the gun bore 2. The optical lens group 9 runs through the interior of the optical system 3 at a certain distance, and passes through the round hole 20 at the bottom of the cylinder cover and the display screen 6 through the signal transmission line 19. Connected, the CMOS image sensor 16 is installed behind the optical lens group 9, and the laser range finder 8 is fixed in front of the lens assembly, which can achieve a laser range measurement of 50 meters to 6 kilometers, and a laser source transmitter 7 is arranged on the top. The cylinder body 11 can be directly replaced by the cartridge case, and the lens assembly is fixed in the cartridge case 11 through the lens holder 10, and the end is provided with a cylinder cover 18. The bottom of the cylinder cover 18 has a round hole 20, and the outside is provided with a handle 15, which is convenient for the optical system. The loading and unloading of 3 can be used for the accurate positioning of display screen 6 simultaneously. Knob 14 is equipped with above the handle 15, similar to the high-speed rail dining table structure. When handle 15 is idle, it can be folded up and locked with knob 14 to save space.

As shown in Fig. 4 and Fig. 5, display screen 6 comprises control button, display window 27, crosshair sight 25, scale mark 26, rechargeable lithium battery 29 and support 28, and control button comprises display window switch button 21, focus adjustment knob 22. Aperture adjustment knob 23. Laser range finder control button 24.

The control button is located at the bottom of the display screen 6 and is used to control the switch and imaging of the device. The central display window 27 superimposes a crosshair sight 25 and a scale line 26. The display screen 6 is equipped with a rechargeable lithium battery 29. The back of the display screen 6 is provided with an inverted The L-shaped bracket 28 can cooperate with the handle 15 at the end of the optical system 3 to mount the display screen 6 on the handle 15 .

The CMOS image sensor 16 includes a control interface, controls such as exposure and white balance, a video timing generation circuit, a photosensitive unit array, an analog signal processing and an A/D conversion circuit.

The CMOS image sensor 16 is responsible for reproducing the image. External light irradiates the pixel array, and a photoelectric effect occurs, which is transmitted to the corresponding analog signal processing unit and A/D conversion circuit, and converted into a digital image signal for output.

The CMOS image sensor 16 is fixed behind the optical lens group 9, and the interface 17 can be pressed down. It is installed like a cell phone battery board and can be installed and removed at any time. The front and rear are restrained by the baffle 12 and the knob 13 respectively. 14, similar to the high-speed rail dining table structure, the CMOS image sensor 16 is connected to the display screen 6 through the signal transmission line 5, the display window 27 is convenient for the gunner to observe the target scene intuitively, and the superimposed crosshair 25 is a reference line for aiming at the target. When the focus adjustment knob 22 is rotated, the focal length can be controlled to become larger or smaller, so as to realize zooming of the scene; when the aperture adjustment knob 23 is rotated, the brightness and darkness of the imaging can be controlled. The rechargeable lithium battery 29 can ensure the long-term working status of the display screen 6, and the support 28 plays the role of accurate positioning of the display screen 6.

When the aiming system of the tank itself is working normally, the device is stored in the gunner's device box. Once the aiming system has a problem, the breech block is opened, and the device is loaded into the gun chamber 2 like a shell. 2 are consistent, can fully cooperate and be well positioned, and have a certain taper, and the taper is consistent with the shell casing. After being loaded into the gun bore 2, it can be automatically centered to ensure that the optical system 3 is consistent with the center of the barrel 1, thereby ensuring aiming accuracy. The display screen 6 is fixed on the handle 15 at the end of the optical system 3 through the inverted L-shaped bracket 28 behind the screen. During the aiming process, it not only saves the additional space required for the display screen 6, but also facilitates the gunner to observe the aiming situation of the display window 27 , to avoid the action of the gunner bowing his head or raising his head.

During the aiming process, the optical system 3 of the device is equipped with multiple groups of lenses, and the front scene is obtained through the gun barrel 1, and then a CMOS image sensor 16 is used to reproduce the image and transmit the image to a small display On the screen 6, it is similar to the camera lens framing process, and it can be zoomed to realize long-distance observation and aiming, and it is presented on the display screen 6. The gunner rotates the turret 4 and adjusts the gun barrel 1 up and down, and when the crosshair sight 25 is aimed at the target, the selected target is completed. Simultaneously, the laser source transmitter 7 on the laser rangefinder 8 can also emit laser light, and observe the laser beam hitting the target on the display screen 6 (the laser beam has a target indication function concurrently), and adopts the mode of observing the laser beam Complete target selection. During the process of the laser beam going back and forth to the target, the laser rangefinder 8 calculates the target distance from the time required for the light to go back and forth, the speed of light and the atmospheric refraction coefficient. If the display window 27 fails to form an image, open the cylinder cover 18, turn the knob 13, take out the CMOS image sensor 16, and aim directly through the imaging of the optical lens group 9. The cylinder cover 18 can be mounted with a buckle or a spiral structure accomplish.

After the crosshairs 25 are aimed at the target in the display screen 6, the device is taken out from the gun bore 2, and the shell is loaded to finish shooting. In the actual shooting and aiming process, when the distance exceeds the direct aiming distance (such as exceeding 2 kilometers), the height of the gun barrel 1 can be slightly raised, that is, there is an elevation angle (shooting angle), to ensure that the shell can be accurately shot when it is fired with a small parabola. In the middle target, the elevation height is regulated by the gunner according to the distance of the target, and is observed and corrected through the scale line 26 in the center of the display window 27, which is similar to the scale line on the telescope lens. According to the temperature, wind direction and force component data provided by the tank integrated information system, through pre-calculated data, corresponding to the corresponding scale, adjust and align the target (at this time, the center of the scale crosshair will not be aligned with the target), so as to improve Hit rates in different climate conditions.

There are four control buttons at the bottom of the display screen 6, and the first one is a display window switch button 21, which controls the display window 27 to work and close. The aperture knob 23 observes the target scene, and rotates the turret 4 and adjusts the gun barrel 1 up and down, regularly completes the selected target, aims at the target, and finally shoots and hits the target. Simultaneously, also can open the 4th control button, i.e. the laser range finder control button 24, the laser range finder 8 emits laser light by the laser source transmitter 7 on the top, observes the laser beam hitting on the target on the display screen 6 , select and hit the target concurrently.

Laser ranging can accurately measure the distance from the artillery to the target, which is helpful for striking targets over 2 kilometers. If the laser ranging system is damaged, the target distance can also be calculated through the scale on the optical lens.

Like this, as long as the gunner aims at the target, and guarantees not to rotate the turret 4 and move the gun barrel 1 substantially, the target is deviated from the range of the crosshair 25 of the display screen 6, the present invention can be taken out and the shell can be loaded to hit the target. In this way, uncertain factors can be eliminated, and the target can be accurately hit in any unexpected situation.

There is no line connection between the invention and the tank, and there is no relative positional relationship. There will be no situation where aiming cannot be caused by the difference, and there is no need to constantly correct the aiming line to be parallel to the axis of the artillery. It can aim at any time when there is a problem with the aiming system of the tank itself. The target, through the mechanical operation of the barrel, achieves a high hit rate static-to-static optical direct-point shooting. At the same time, if the CMOS imaging system fails, the CMOS imaging system can also be removed, and the eyes can directly aim at the target through the lens. At this time, it is like aiming at the target through an optical sight (or similar to a telescope), so there is better redundancy. to meet the emergence of various complex situations on the battlefield.

The above description is only the preferred mode of the present invention. It should be pointed out that those skilled in the art can make several similar deformations and improvements without departing from the inventive concept of the present invention, and these should also be regarded as within the protection scope of the present invention.
