Description

Technical Field

[0001] This invention relates to the field of artillery testing technology, and in particular to an artillery zero-position correction and gun adjustment accuracy testing system. Background Technology

[0002] In existing technologies, artillery zero-position calibration and gun adjustment accuracy testing are two independent and cumbersome operational processes, typically relying on traditional optical instruments, mechanical measuring tools, and extensive manual operation and interpretation. Zero-position calibration requires towing the artillery to a specific flat area, using tools such as levels and calibrators, and involving multiple people working together to repeatedly observe and adjust the gun. This process is time-consuming and has stringent environmental requirements. Gun adjustment accuracy testing, on the other hand, often relies on rough methods such as manual timing with a stopwatch and visual observation and marking. This results in significant human error, low data reliability, and an inability to intuitively and quantitatively display key indicators such as drift. The entire process is not only inefficient, requiring close cooperation from 4-5 professionals and taking over two hours, but its accuracy is also significantly affected by personnel skills and environmental factors, making it difficult to meet the demands of modern artillery for rapid and precise support. Summary of the Invention

[0003] In view of this, in order to solve the problems existing in the technical background, the present invention proposes a gun zero-position correction and gun adjustment accuracy detection system. Specifically, it includes the following: A gun zero-position correction and gun adjustment accuracy detection system includes: a base forming the bottom support structure of the system; the base is provided with a first gear, a second gear, a horizontal axis, a vertical axis, and a first digital display screen; one end of the horizontal axis is connected to the first gear and the other end is connected to the inner wall of the base; one end of the vertical axis is connected to the second gear and the other end is connected to the inner wall of the other side of the base; the horizontal axis and the vertical axis are arranged in a horizontal cross shape; an upper layer is provided above the base; the upper layer includes a second digital display screen, a laser red dot indicator, a power supply module, an tilt indicator, a circuit board processing system, and an optical system; the second digital display screen is provided on the side wall of the upper layer; the power supply module, the circuit board processing system, and the tilt indicator are provided inside the upper layer; the optical system is provided at one end of the upper layer and the laser red dot indicator is provided at the other end.

[0004] Furthermore, the tilt indicator is used to detect the horizontal attitude of the system and transmit the attitude information to the circuit board processing system, and the first digital display screen is used to receive and display the adjustment amount or error value reflecting the horizontal attitude of the system processed by the circuit board processing system.

[0005] Furthermore, the laser red dot indicator generates an indicator light spot under the power supply of the power supply module, and the circuit board processing system is configured to control the second digital display screen to start displaying angle parameters or time parameters related to the rotation of the cannon barrel when the indicator light spot is offset relative to a predetermined reference position.

[0006] Furthermore, the rotation angle parameters displayed on the second digital display screen are in mils, and the circuit board processing system can accumulate and display a total rotation angle of more than 360 degrees.

[0007] Furthermore, the horizontal axis and the vertical axis can be driven independently through the transmission of the first gear and the second gear to adjust the horizontal posture of the base and the upper layer in the horizontal and vertical directions.

[0008] Furthermore, the first gear and the second gear are connected to a manual adjustment unit. By operating the manual adjustment unit, the corresponding gear is driven, thereby driving the horizontal or vertical axis to move to achieve horizontal fine adjustment.

[0009] Furthermore, the power supply module is a switchable power supply mode module, capable of selecting power supply via an external power source or via an internal battery.

[0010] Furthermore, the optical system includes an optical lens group for compressing the divergence angle of the beam emitted by the laser red dot indicator device, so that the indicator light spot forms a small light spot at a set distance.

[0011] Furthermore, the bottom surface of the base is provided with a magnetic attraction device, which is used to adsorb and fix the entire system onto the reference plane of the artillery vehicle body or the artillery barrel.

[0012] The above technical solution has the following beneficial effects: This invention represents a significant breakthrough in operational efficiency, optimizing a complex process that previously required hours and multiple personnel to be completed in approximately ten minutes by just two people, greatly improving support speed. It reduces dependence on the work site, eliminating the need for a perfectly flat, dedicated area, and enhancing the equipment's adaptability and rapid deployment capabilities in field conditions. Regarding gun aiming accuracy testing, it achieves automated measurement and digital display, allowing operators to independently complete the testing and directly and accurately read the gun's rotation angle (mil) or time parameters. This effectively eliminates human observation and timing errors, enabling precise quantification and evaluation of key accuracy indicators such as gun azimuth drift and rotation uniformity.

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] See Figure 1 The artillery zero-position correction and gun adjustment accuracy detection system shown includes: a base 1 forming the bottom support structure of the system; a first gear 2, a second gear 3, a horizontal axis 4, a vertical axis 5, and a first digital display screen 6 are provided on the base 1; one end of the horizontal axis 4 is connected to the first gear 2 and the other end is connected to the inner wall of the base 1; one end of the vertical axis 5 is connected to the second gear 3 and the other end is connected to the inner wall of the other side of the base 1; the horizontal axis 4 and the vertical axis 5 are arranged in a horizontal cross shape; an upper layer is provided above the base 1; the upper layer includes a second digital display screen 8, a laser red dot indicator device 9, a power supply module 10, an tilt indicator device 7, a circuit board processing system 11, and an optical system 12; the second digital display screen 8 is provided on the side wall of the upper layer; the power supply module 10, the circuit board processing system 11, and the tilt indicator device 7 are provided inside the upper layer; the optical system 12 is provided at one end of the upper layer and the laser red dot indicator device 9 is provided at the other end.

[0016] The tilt indicator 7 is used to detect the horizontal attitude of the system and transmit the attitude information to the circuit board processing system 11. The first digital display screen 6 is used to receive and display the adjustment amount or error value reflecting the horizontal attitude of the system processed by the circuit board processing system 11.

[0017] The laser red dot indicator 9 generates an indicator light spot under the power supply of the power supply module 10. The circuit board processing system 11 is configured to control the second digital display screen 8 to start displaying angle parameters or time parameters related to the rotation of the cannon barrel when the indicator light spot is offset relative to a predetermined reference position.

[0018] The rotation angle parameters displayed on the second digital display screen 8 are in micrometers, and the circuit board processing system 11 can accumulate and display a total rotation angle of more than 360 degrees. The horizontal axis 4 and the vertical axis 5 can be driven independently through the transmission of the first gear 2 and the second gear 3 to adjust the horizontal posture of the base 1 and the upper layer in the horizontal and vertical directions. The first gear 2 and the second gear 3 are connected to a manual adjustment part. By operating the manual adjustment part, the corresponding gear is driven, thereby driving the horizontal axis 4 or the vertical axis 5 to move to achieve horizontal fine adjustment. The power supply module 10 is a switchable power supply mode module, which can be powered by an external power supply or by an internal battery.

[0019] The optical system 12 includes an optical lens group for compressing the divergence angle of the beam emitted by the laser red dot indicator 9, so that the indicator light spot forms a small light spot at a set distance.

[0020] The bottom surface of the base 1 is provided with a magnetic attraction device, which is used to adsorb and fix the entire system onto the reference plane of the artillery vehicle body or the artillery barrel.

[0021] The system adopts a layered integrated design, mainly composed of a base 1, an intermediate transmission and adjustment layer, and an upper functional module. The base 1 forms the system's mounting base, and its bottom surface undergoes special treatment, such as embedding strong magnets or arranging magnetic arrays, to firmly adhere to the top of the artillery vehicle or a designated reference surface at the breech, ensuring no displacement or detachment during subsequent gun adjustment and rotation, providing a stable mounting foundation for the entire testing process. A horizontal adjustment mechanism is located inside the upper part of the base 1, comprising a transversely arranged horizontal axis 4 and a longitudinally arranged vertical axis 5, forming a horizontal cross. One end of the horizontal axis 4 is connected to a manual adjustment part located on the side wall of the base 1 via a first gear 2, while the other end is connected to a support on the inner wall of the base 1; similarly, the vertical axis 5 is connected to another manual adjustment part via a second gear 3. By rotating the two manual adjustment parts, the first gear 2 and the second gear 3 can be driven independently, thereby causing the horizontal axis 4 or the vertical axis 5 to produce slight lifting movements. This design allows operators to independently and precisely fine-tune the system's horizontal attitude in both the transverse and longitudinal directions to adapt to the initial state of different reference surfaces.

[0022] The system's horizontal status monitoring and indication are jointly accomplished by the tilt indicator 7 and the first digital display screen 6. The tilt indicator 7, built into the upper-level functional module, detects the overall lateral and longitudinal tilt angles of the system in real time and sends the tilt data to the circuit board processing system 11. The circuit board processing system 11 processes the received data, driving the first digital display screen 6 to display the current horizontal deviation value or suggested adjustment amount required for leveling, with a display accuracy of up to two decimal places. This data also provides a reference for subsequent automated processes. Following the guidance of the first digital display screen 6, the operator operates the manual adjustment unit in the corresponding direction until the displayed horizontal error is within the allowable range, thus completing the initial leveling based on the vehicle body plane. This process is fast and intuitive, greatly reducing the difficulty of traditional bubble centering observation and the reliance on operator experience.

[0023] The upper-level functional modules integrate core functions such as power supply, laser indication, signal processing, and display. The power supply module 10 adopts a switchable design, allowing it to operate via an external adapter using AC power or relying on a built-in high-capacity rechargeable battery, ensuring continuous operation in the field without a fixed power source. The laser red dot indicator 9 consists of a laser emitter, an optical system 12, and a drive circuit. The optical system 12 includes a set of precision lenses to compress the divergence angle of the laser beam, enabling the laser to form a small, clear spot at a set distance, serving as a precise spatial reference point. The circuit board processing system 11 acts as the "brain" of the entire system, coordinating the operation of each module. After zero-position calibration, during gun accuracy testing, the laser red dot indicator 9 is activated, aligning its emitted spot with and illuminating the center of a pre-fixed sensing target plate at a certain distance behind. When the gun's azimuth mechanism is rotated, the gun barrel rotates along with the system, causing the laser spot to deviate from the sensing target plate. The sensing target plate detects the spot's departure and sends a trigger signal to the circuit board processing system 11.

[0024] Upon receiving a trigger signal, the circuit board processing system 11 immediately initiates its internal high-precision timing and angle calculation program. The system continuously receives real-time angle change data from the tilt indicator 7, or combines this data with data from the built-in gyroscope sensor, to calculate the rotation angle of the gun barrel in real time. The calculation results are processed and accumulated in mils, driving the second digital display screen 8 for dynamic display. The second digital display screen 8 is typically located on the upper side wall for easy operator observation. It not only displays the real-time rotation mil value but also accumulates and displays the total number of rotations and angles exceeding 360 degrees (6000 mils), and simultaneously displays the time taken to rotate a specific angle. This design allows the operator to directly and quantitatively obtain key performance parameters such as the uniformity, stability, and presence of jamming or slippage of the gun's azimuth mechanism, achieving automation and digitization of gun aiming accuracy detection and completely eliminating errors caused by manual timing and visual interpretation.

[0025] The power supply is designed with both external and battery modes to adapt to field operation environments.

[0026] In practice, after the system is fixed to the reference surface of the artillery vehicle, the operator first makes minor horizontal adjustments based on the real-time feedback from the first digital display screen 6. The first digital display screen 6 receives tilt data processed by the circuit board processing system 11 and displays the current horizontal deviation values ​​of the system in the lateral and longitudinal directions in digital form, with an accuracy of 0.01 mil. The operator rotates the two manual adjustment parts connecting the first gear 2 and the second gear 3, driving the horizontal axis 4 and the vertical axis 5 to independently produce slight increases and decreases, thereby adjusting the horizontal attitude of the entire upper part of the system. When the first digital display screen 6 shows that both the lateral and longitudinal deviations are close to zero, it indicates that the system has been precisely leveled, and this state establishes the initial mechanical zero-position reference with the vehicle's plane as the reference. This process replaces the traditional method of relying on visual observation of the level bubble centering, significantly reducing the dependence on operator experience and improving the speed and accuracy of leveling.

[0027] Transfer and securely install the system onto the dedicated testing interface or flat surface at the breech of the artillery. At this point, the system has acquired initial zero-position information. Operate the artillery's elevation and traverse mechanisms to move the system along with the gun barrel, and observe the first digital display screen 6 again. Fine-tune the artillery mechanism to return the display reading to zero. This step completes the precise alignment of the artillery's mechanical zero position with the vehicle's reference. Theoretically, in this state, when the artillery's traverse mechanism rotates, the system's horizontal attitude should remain stable, and the reading on the first digital display screen 6 should remain near zero. This characteristic can be used to verify the repeatability and stability of the zero-position correction.

[0028] When performing gun aiming accuracy testing, the laser red dot indicator 9 and the second digital display screen 8 are activated. Driven by the power supply module 10, the laser red dot indicator 9 emits a laser beam. After the beam passes through a precision lens group in the optical system 12 to compress the divergence angle, it forms a small and clear spot at a set distance. The operator must pre-position a photoelectric sensing target plate approximately one meter behind the gun and precisely align the laser spot with the center of the target plate. When the gun's azimuth mechanism is rotated at a constant speed or according to procedure, the gun's rotation causes the system to move synchronously, and the laser spot immediately deviates from the sensing target plate. The sensing target plate sends a trigger signal to the circuit board processing system 11 the instant it detects the spot's departure.

[0029] Upon receiving a trigger signal, the circuit board processing system 11 immediately activates its integrated precision timing and angle calculation functions. The system continuously collects real-time angle change data from the tilt indicator 7 or the built-in gyroscope sensor, and uses an internal algorithm to calculate the instantaneous angular velocity and cumulative angle of the gun barrel rotation in real time. This data is transmitted in real-time to the second digital display screen 8 for dynamic display. The display screen clearly shows the cumulative rotation angle in mils and has a multi-turn accumulation function, capable of displaying a total rotation of over 360 degrees. Simultaneously, the screen can also display the time taken to rotate a specific angle or directly display the real-time rotation speed. By observing these dynamic parameters, operators can intuitively and quantitatively assess the uniformity and stability of the gun's azimuth mechanism rotation, accurately detect the presence of backlash error, nonlinear drift, or jamming, thereby comprehensively and efficiently completing the automated detection of gun aiming accuracy.
