[0022] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0023] As Figure 1 shown, an embodiment of the present utility model provides a gun elevation accuracy test system, including:

[0024] The first theodolite detection unit 3 is configured to emit a laser to a marking point parallel to the shooting direction of the gun barrel 2, and obtain the horizontal angle and vertical angle of the marking point of the gun barrel 2 before and after gun elevation; the first theodolite detection unit 3 includes a first laser emitter, a first emitter horizontal adjustment device, a first emitter vertical adjustment device, a first laser receiver, a first control module, and a first communication module; the first laser emitter is electrically connected to the first emitter horizontal adjustment device and the first emitter vertical adjustment device respectively, the first laser receiver is electrically connected to the first data processing module, and the first communication module, the first data processing module, the first emitter horizontal adjustment device, and the first emitter vertical adjustment device are electrically connected to the first control module respectively;

[0025] The second theodolite detection unit 4 is configured to emit a laser to a marking point parallel to the shooting direction of the gun barrel 2, and obtain the horizontal angle and vertical angle of the marking point of the gun barrel 2 before and after gun elevation; the second theodolite detection unit 4 includes a second laser emitter, a second emitter horizontal adjustment device, a second emitter vertical adjustment device, a second laser receiver, a second control module, and a second communication module; the second laser emitter is electrically connected to the second emitter horizontal adjustment device and the second emitter vertical adjustment device respectively, the second laser receiver is electrically connected to the second data processing module, and the second communication module, the second data processing module, the second emitter horizontal adjustment device, and the second emitter vertical adjustment device are electrically connected to the second control module respectively;

[0026] The test central control unit 5 is used to receive the angular change data of the marked points on the gun barrel 2 before and after gun adjustment sent by the first longitude and latitude detection unit 3 and the second longitude and latitude detection unit 4, and output the gun adjustment accuracy result; the test central control unit 5 is electrically connected to the first longitude and latitude detection unit 3 and the second longitude and latitude detection unit 4 respectively; the test central control unit 5 includes a central control module, an interface module, a wireless communication module and a power supply module, and the power supply module provides the required electric energy for the central control module, the wireless communication module and the interface module, and the interface module and the wireless communication module are electrically connected to the central control module.

[0027] It should be noted that with reference to Figure 1 , the marked points of the gun can be set according to the specific structural characteristics of the gun barrel, such as the protrusions on the outside of the gun barrel 2 and specific painting patterns. In a specific case, we assume that marked points are provided at both ends of the gun barrel 2, which include marked point a and marked point b, and the connection line between marked point a and marked point b is parallel to the firing direction of the gun barrel.

[0028] It should be further noted that this application includes two independent longitude and latitude detection units. Each longitude and latitude detection unit is fixedly supported by a detachable bracket below. Each longitude and latitude detection unit can emit laser to the marked points at both ends of the gun barrel 2 and collect angular data, so that the system can measure the gun barrel 2 of the gun from two different angles. The laser emitter in each longitude and latitude detection unit can be connected to the horizontal and vertical adjustment devices to achieve automatic adjustment to adapt to the change of the pose of the gun barrel 2. The automated adjustment mechanism reduces the need for manual operation and further improves the measurement accuracy; through the laser emitter and receiver, the system can accurately measure the changes in the horizontal and vertical angles of the gun barrel 2; the test central control unit 5 includes multiple modules, such as an interface module, a wireless communication module and a power management module, which are electrically connected to the central control module, realizing the modular design of the system, facilitating maintenance and upgrading. The design of the interface module and the wireless communication module realizes the wired / wireless data transmission between the test central control unit 5 and the longitude and latitude detection unit, and the power supply module ensures the power supply required for the stable operation of the system, increasing the flexibility and environmental adaptability of the system, especially in field or mobile environments; the central control module receives data from the two longitude and latitude detection units and outputs the gun adjustment accuracy result through comprehensive analysis, realizing the rapid and accurate evaluation of the gun adjustment accuracy of the gun.

[0029] As a further solution, the first emitter horizontal adjustment device and the first emitter vertical adjustment device receive control instructions from the first control module to adjust the angle at which the first laser emitter emits laser following the change of the pose state of the gun barrel 2; the second emitter horizontal adjustment device and the second emitter vertical adjustment device receive control instructions from the second control module to adjust the angle at which the second laser emitter emits laser following the change of the pose state of the gun barrel.

[0030] It should be noted that the emitter adjustment device receives control instructions from their respective control modules according to the changes in the pose state of the gun barrel 2, and automatically adjusts the angle of the laser emitter. Specifically, the first emitter horizontal adjustment device and the first emitter vertical adjustment device adjust the angle of the first laser emitter according to the instructions of the first control module to ensure that the laser accurately hits the marked points a and b on the gun barrel 2. Similarly, the horizontal and vertical adjustment devices of the second emitter also adjust the angle of the second laser emitter according to the instructions of the second control module to achieve precise aiming at the marked points a and b. This automatic adjustment mechanism not only reduces the complexity of manual operation, but also improves the response speed and accuracy of measurement, enabling the system to quickly adapt to the changes in the pose of the gun barrel 2 and achieve efficient and accurate gun adjustment accuracy measurement. Through this design, stable and reliable measurement results can be ensured under various operating conditions, greatly improving the efficiency and effectiveness of the gun adjustment accuracy test of the artillery.

[0031] As a further solution, a first laser reflection device and a second laser reflection device are respectively arranged at the marked points where the shooting directions of the gun barrel 2 are parallel. Both the first laser reflection device and the second laser reflection device are used to reflect the laser emitted by the laser emitter.

[0032] As a further solution, both the first laser reflection device and the second laser reflection device are arranged by using a reflective film, and the reflective film is wrapped around the marked points where the shooting directions of the gun barrel are parallel.

[0033] It should be noted that in order to enhance the reflection effect of the laser reflection device and simplify the installation process, the reflection device in this technical solution uses a reflective film material, which can be tightly wrapped around the marked points a and b at both ends of the gun barrel, providing a stable and efficient reflection surface. It not only ensures the accurate reflection of the laser signal, but also simplifies the installation and operation process of the system, making the whole system more efficient and user-friendly. Moreover, due to the flexibility and durability of the reflective film, it can also adapt to gun barrels of different sizes and shapes, making the system have better versatility and adaptability.

[0034] As a further solution, the first laser receiver is used to receive the first laser signal reflected from the first laser reflection device, convert the first laser signal into a first electrical signal and send it to the first data processing module; the second laser receiver is used to receive the second laser signal reflected from the second laser reflection device, convert the second laser signal into a second electrical signal and send it to the second data processing module.

[0035] As a further solution, the first data processing module and the second data processing module process and analyze the received first laser signal and second laser signal to obtain the change data of the horizontal angle and vertical angle of the gun barrel marking points before and after the gun barrel changes its pose, and send the change data of the horizontal angle and vertical angle to the first control module and the second control module respectively.

[0036] It should be noted that the first data processing module and the second data processing module obtain the propagation time of the laser signal by measuring the time from the emission to the reception of the laser signal. Combining the known speed of light, the actual propagation distance of the laser signal can be calculated. At the same time, combining the relative positions of the laser emitter and the receiver, as well as the emission and reception angles of the laser signal, the data processing module uses the principle of trigonometric functions to calculate the horizontal and vertical angle change data of the marking points a and b of the gun barrel 2.

[0037] As a further solution, the interface module of the test central control unit 5 includes a first D89 interface and a second D89 interface. The first control module of the first latitude and longitude detection unit 3 is electrically connected to the test central control unit 5 through the first D89 interface, and the second control module of the second latitude and longitude detection unit 4 is electrically connected to the test central control unit 5 through the second D89 interface.

[0038] As a further solution, the first communication module of the first latitude and longitude detection unit 3 and the second communication module of the second latitude and longitude detection unit 4 perform wireless communication with the wireless communication module of the test central control unit 5 to realize data transmission and interaction between the test central control unit 5, the first latitude and longitude detection unit 3, and the second latitude and longitude detection unit 4.

[0039] As a further solution, the test central control module of the test central control unit 5 receives the change data of the horizontal angle and vertical angle of the gun barrel marking points before and after the gun is adjusted from the first control module of the first latitude and longitude detection unit 3 and the second control module of the second latitude and longitude detection unit 4 through wired / wireless transmission, and obtains the azimuth angle and elevation angle accuracy of the gun barrel through the angle change data.

[0040] It should be noted that in the test central control unit 5, the angle changes before and after the gun adjustment are combined and compared and analyzed through the built-in algorithm of the module to determine the adjustment accuracy of the gun barrel 2; according to the positioning information of the marking points a and b at both ends of the gun barrel 2 in the space coordinate system, the precise position of the marking points relative to the reference coordinate system is obtained by using laser ranging and angle measurement technologies, and the azimuth angle and elevation angle data of the gun barrel 2 in space are analyzed.

[0041] As a further solution, the test central control unit 5 further includes a touch display screen for the test central control module to display the gun adjustment accuracy result through the touch display screen.

[0042] It should be noted that through the touch display screen, the operator can not only instantaneously view the dynamic changes during the gun barrel 2's gun adjustment process, but also directly interact with the test central control module through the touch screen to perform various operations, such as starting the measurement program, adjusting settings, or viewing historical data. The test central control unit 5 can remotely receive real-time data from the first theodolite detection unit 3 and the second theodolite detection unit 4 without physical connection, eliminating the need for wiring. In the case of an emergency in the field, the operator can still quickly move to a safe location to monitor the gun adjustment situation of the howitzer without being restricted by cables.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
