Description

Technical Field

[0001] The present invention belongs to the field of measurement technology, and in particular relates to a precision measurement method, system and storage medium for an artillery fire control system in a field environment. Background Art

[0002] Artillery is the army's suppression weapon. However, with the emergence and deployment of counter-artillery weapons such as artillery reconnaissance and positioning radar, artillery combat methods have undergone significant changes. To prevent counter-artillery weapons from detecting, locating, and destroying artillery and positions, artillery units have begun to shift from static strikes and heavy fire suppression to dynamic, rapid-attack-and-withdrawal tactics.

[0003] After fire control systems were gradually installed on various new artillery pieces, the method for calculating artillery strike parameters shifted from manual to computer-based calculations, significantly reducing the time required for artillery strikes and relocations. However, with the increasing frequency of combat exercises in recent years, the frequency of artillery deployments has increased significantly. The alternating loads generated during the deployment process in the gear mechanisms of the artillery's elevation and steering mechanisms are prone to failures such as tooth root bending fatigue and tooth surface contact fatigue, which increases gear backlash and system errors. At the same time, the fire control system's aging and gyroscope failures can also reduce the accuracy of fire control and gun adjustment, resulting in a decline in the application and promotion of fire control systems and an inability to fully utilize the equipment's combat effectiveness.

[0004] In summary, there is an urgent need for a new accuracy measurement method for artillery fire control systems in field environments to achieve artillery fire control accuracy detection. Summary of the Invention

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0050] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0051] The purpose of the present invention is to complete the measurement of the directional angle accuracy and elevation angle accuracy of the artillery fire control system using the traditional 58-type steering wheel (hereinafter referred to as the steering wheel), periscope and rear sight setter of the artillery unit in the case of relative scarcity of various precision detection equipment in field combat environments. In order to better meet the training needs of artillery units, the angles involved in the present invention all adopt the micro-position system. The steps of the present invention for the directional angle accuracy detection of the fire control gun are as follows: the artillery enters the designated detection area, the direction of the gun barrel is basically consistent with the reference firing direction when the gun is in the natural gun state, the directional angle accuracy of the fire control gun is detected by the steering wheel that has been assigned the firing direction, and the elevation angle accuracy of the fire control gun is detected by the rear sight setter. The present invention is not limited by the model of the artillery and is applicable to all types of artillery equipped with a fire control system.

[0052] See also Figure 1 and Figure 2 The present invention provides a method for measuring the accuracy of an artillery fire control system in a field environment. The method includes but is not limited to the following steps:

[0053] S100: A reference firing direction is given to a gun, wherein the gun has a periscope and a steering wheel.

[0054] The steering wheel can be the traditional Type 58 steering wheel used by artillery units. This is a fire control instrument used by artillery battalions and companies, consisting of an optical observation instrument (telescope, etc.), a goniometer, and a directional compass. It is primarily used to measure magnetic azimuth, direction, and elevation, providing a baseline for artillery firing. It can also be used to observe projectile deviation or, in conjunction with a rangefinder (benchmark), measure distance within a certain range.

[0055] The periscopic sight is a universal sight for artillery, used for directional aiming and calibration of artillery. As an angle measuring and aiming instrument, its angle reading should be accurate, reliable, sensitive, stable, fast and convenient. There are many types of angle reading devices, including mechanical, optical, photoelectric and so on. At present, there are two typical instruments of periscopic sights, namely the scale reading type periscopic sight and the multi-wheel reading type periscopic sight, and their angle reading devices are both mechanical. The angle reading of the Type 84 periscopic sight uses a gear-driven digital roller, which is a multi-wheel reading device. When rotating, the gear drives the lens to rotate while the digital roller counter works synchronously to display the micro-position value of the angle.

[0056] Specifically, find an open, flat area and assign the gun a reference firing direction. Ensure that the gun barrel's orientation remains roughly consistent with this reference firing direction when the gun is in natural firing mode. The gunner deploys the gun and inserts the gun's built-in periscope into the gun's scope mount. A magnetically corrected steering wheel is set up approximately 200 meters to the left and rear of the gun barrel, where it will not affect the periscope's field of view.

[0057] S200: completing the assigned direction of the steering wheel according to the given reference direction, wherein the red point of the steering wheel is assigned to 000 mil.

[0058] The mil is a commonly used military unit of angle measurement. A circle's circumference is divided into 6,000 equal parts (some countries divide it into 6,300 or 6,400 parts), and the arc length of each part corresponds to the central angle of the circle, which is one mil. The arc length corresponding to one mil is roughly equal to one thousandth of the radius.

[0059] S300: Turn the steering wheel to the direction of the periscope aimed at the artillery, and record the red scale value A at this time.

[0060] S400: Use the fire control system to adjust the gun barrel to the direction of the reference firing direction, and rotate the periscope to align with the steering wheel, and record the scale value B of the periscope at this time, wherein the initial scale value of the periscope is 3000 mils.

[0061] S500: Determine the gun adjustment accuracy δ assigned to the gun by the fire control system based on the actual rotation angle β of the periscope and the actual rotation angle α of the steering wheel, wherein β = B-3000, α = 6000-A, and δ = α+β-3000.

[0062] The accuracy measurement method of the fire control system of an artillery in a field environment provided by the present invention is as follows: first, a reference firing direction is given to the artillery, and the artillery has a periscopic sight and a steering wheel; then, the steering wheel is assigned a firing direction according to the given reference firing direction, wherein the red scale of the steering wheel is classified as 000 mil; the steering wheel is rotated to the direction of the periscopic sight aligned with the artillery, and the red scale value at this time is recorded; then, the fire control system is used to adjust the barrel of the artillery to the direction of the reference firing direction, and the periscopic sight is rotated to the direction aligned with the steering wheel, and the scale value of the periscopic sight at this time is recorded; finally, according to the actual rotation angle of the periscopic sight and the actual rotation angle of the steering wheel, the accuracy of the gun adjustment assigned to the artillery by the fire control system is determined. The technical solution of the present application can detect the accuracy of the fire control gun adjustment direction angle through the steering wheel that has completed the assignment of the firing direction, is not limited by the artillery model, and is applicable to all types of artillery equipped with a fire control system.

[0063] Please continue reading Figure 3 In some embodiments, after step S500, the method further includes but is not limited to the following steps:

[0064] S510: Determine the magnitude relationship between the gun adjustment accuracy δ assigned to the gun by the fire control system and the number 0.

[0065] S520: If it is determined that δ=0, it is determined that the gun adjustment accuracy δ assigned to the firing direction by the fire control system meets the actual combat and training requirements; if it is determined that δ<0, it is determined that the firing direction assigned by the fire control system is deviated to the left by δ mils; if it is determined that δ>0, it is determined that the firing direction assigned by the fire control system is deviated to the right by δ mils.

[0066] Specifically, the gun direction adjustment accuracy δ assigned by the fire control system to the gun is compared with 0, and based on the comparison result, the mils assigned by the fire control system to the preset direction and value are corrected. When the gun direction adjustment accuracy δ assigned by the fire control system to the gun is equal to 0, it indicates that the gun direction adjustment accuracy δ assigned by the fire control system meets the requirements of actual combat and training, and no correction is required. When the gun direction adjustment accuracy δ assigned by the fire control system to the gun is less than 0, it indicates that the gun direction adjustment accuracy δ assigned by the fire control system is biased to the left by mils. When the gun direction adjustment accuracy δ assigned by the fire control system to the gun is greater than 0, it indicates that the gun direction adjustment accuracy δ assigned by the fire control system is biased to the right by mils. In this way, the deviation pattern of the gun direction adjustment accuracy δ assigned by the fire control system to the gun can be determined, facilitating subsequent correction of the gun direction adjustment accuracy δ assigned by the gun.

[0067] Please continue reading Figure 4 In some embodiments, after step S520, the method further includes but is not limited to the following steps:

[0068] S530: Obtain an average correction accuracy Δ of the direction assigned by the fire control system using the fire control system and the steering wheel n times, wherein the

[0069] Where n is a natural number. Theoretically, the larger the value of n, the more accurate the average correction accuracy assigned to the firing direction by the fire control system. In actual operation, the value of n can be 5, 10, 15, etc.

[0070] S540: Determine the actual firing direction μ assigned by the fire control system of the gun according to the difference between the reference firing direction γ of the gun and the average correction accuracy Δ of the firing direction assigned by the fire control system.

[0071] Specifically, μ = γ - Δ, that is, the difference between the reference direction γ of the artillery such as the direction μ actually assigned by the artillery fire control system and the average correction accuracy Δ of the direction assigned by the fire control system. The corrected actual assigned direction μ can well correct the direction of the artillery fire control system, thereby improving the accuracy of the artillery fire control system in launching artillery shells.

[0072] Please continue reading Figure 5 In some embodiments, after step S540, the method further includes but is not limited to the following steps:

[0073] S550: Correcting the error of the firing direction assigned by the artillery fire control system according to the firing direction actually assigned by the artillery fire control system.

[0074] Specifically, the actual firing direction of the artillery fire control system is corrected by the corrected actual assigned firing direction μ, so as to reduce the error of the firing direction assigned by the artillery fire control system, thereby improving the accuracy of the actual firing of the artillery shells by the artillery fire control system.

[0075] Please continue reading Figure 6 In some embodiments, after step S550, the method further includes but is not limited to the following steps:

[0076] S560: Use the modified artillery fire control system to assign a firing direction to the artillery, and align the periscope with the position of the steering wheel. At this time, the graduation value of the periscope is C1.

[0077] S570: Give the gun barrel a 100-mil azimuth command to the left or right through the gun fire control system, rotate the periscope again to a position aligned with the steering wheel, and record the periscope graduation value C2 at this time.

[0078] S580: Determine the directional angle error c of the gun barrel according to the periscope graduation value C1 and the periscope graduation value C2, wherein c=C2-C1-100.

[0079] Among them, the directional angle command of 100 mils to the left or right given to the gun barrel by the artillery fire control system is only for reference in one case. In other embodiments, the directional angle command of 200 mils to the left or right can be given to the gun barrel. In this case, the calculation formula for adjusting the directional angle error c of the gun barrel must be adaptively adjusted.

[0080] Please continue reading Figure 7 In some embodiments, after step S580, the method further includes but is not limited to the following steps:

[0081] S590: When it is determined that the directional angle error c of the gun barrel is equal to 0, it is determined that the directional angle of the gun barrel can be automatically adjusted by the gun fire control system; otherwise, it is determined that the directional angle of the gun barrel adjusted by the gun fire control does not meet the requirements and the manual adjustment of the directional angle of the gun barrel should be switched.

[0082] Specifically, if the error c is greater than or less than zero and the error is large, the fire control gun adjustment direction angle does not meet the requirements and should be switched to manual gun adjustment; if the error c is small or equal to zero, the direction angle can be automatically adjusted by the fire control system.

[0083] Specific implementation conditions: For a certain type of artillery equipped with a fire control system, the fire control system can be used. The reference firing directions input into the fire control system are 1500, 3000 and 4500 mils respectively. The accuracy of the firing directions assigned by the fire control system is tested respectively. The test results are shown in Tables 1 to 3. After the firing direction is assigned and the accuracy correction of the firing direction assigned by the fire control is performed, the fire control system is given commands of ±100 and ±200 mils of reference firing directions respectively. The angle error between the gun adjustment direction angle and the actual rotation of the gun barrel is detected through the gun periscope. The test results are shown in Table 4. The parameter letters used in the table have the same meaning as the letters in the steps.

[0084] Table 1 Angle relationship table of a certain artillery's reference firing direction at 1500 mils

[0085]

[0086] Table 2 Angle relationship table of a certain artillery reference firing direction 3000 mils

[0087]

[0088] Table 3 Angle relationship table of a certain artillery reference firing direction 4500 mils

[0089]

[0090] The measurement results in Tables 1 to 3 show that the accuracy of the fire control-assigned direction is unrelated to the gun's reference direction selection and is solely related to the gun's own system error. The gun's direction, based on the fire control system's assigned direction, deviated approximately 0.01 mil to the right of the actual reference direction. After correcting the fire control system's assigned direction accuracy, the error between the gun's fire control system's angle of adjustment and the actual barrel rotation angle can be measured to determine the accuracy of the fire control's direction of adjustment.

[0091] Table 4 Error between the gun adjustment angle of a gun fire control system and the actual rotation angle of the gun barrel

[0092]

[0093]

[0094] According to the results in Table 4, the fire control system's gun direction angle adjustment has nothing to do with the assigned firing direction value, but is only related to its own system error. The overall gun adjustment is 0.01 mils to the right. If the firing distance is 10 km, the deviation is about 10 meters. Within the killing range of the artillery shell, the fire control system's gun direction angle adjustment accuracy is relatively high.

[0095] Please continue reading Figure 8 and Figure 9 In some embodiments, the method further includes but is not limited to the following steps:

[0096] S600: Given a sight θ for the artillery fire control system, the artillery fire control system is used to adjust the elevation angle of the gun barrel.

[0097] S700: Adjust the sight setter until the level bubble is centered and record the sight setter value. The value The gun fire control system actually adjusts the gun barrel elevation angle.

[0098] S800: According to the sight θ and the sight setting device value The difference between them is the positional relationship ω.

[0099] S900: When it is determined that the positional relationship ω is equal to 0, it is determined that the elevation angle of the gun barrel adjusted by the artillery fire control system meets the actual training and combat requirements; when it is determined that the positional relationship ω is greater than 0, it is determined that the actual value of the elevation angle of the gun barrel adjusted by the artillery fire control is less than a given value |ω| mils; when it is determined that the positional relationship ω is less than 0, it is determined that the actual value of the elevation angle of the gun barrel adjusted by the artillery fire control is greater than a given value |ω| mils.

[0100] By comparing the sight θ with the sight setting device value The difference between them can be used to obtain the positional relationship ω between the two. Based on the relationship between the positional relationship ω and 0, the relationship between the actual value of the elevation angle of the gun barrel adjusted by the artillery fire control and the given value can be determined, which facilitates the subsequent correction of the error.

[0101] Please continue reading Figure 10 In some embodiments, after step S900, the method further includes but is not limited to the following steps:

[0102] S1000: Utilizing the sight setter n times to detect the elevation angle accuracy of the gun barrel adjusted by the gun fire control system, the correction accuracy Δω of the sight can be calculated, wherein

[0103] Where n is a natural number. Theoretically, the larger the value of n, the more accurate the average correction accuracy assigned to the firing direction by the fire control system. In actual operation, the value of n can be 5, 10, 15, etc.

[0104] S1100: Determine the actual input sight ν of the artillery fire control system based on the sight θ and the correction accuracy Δω of the sight, wherein ν = θ + Δω.

[0105] S1200: Adjusting the elevation angle of the gun barrel of the gun fire control system according to the actual input sight v of the gun fire control system. Firing the projectile with the corrected elevation angle of the gun barrel can improve firing accuracy.

[0106] Specific implementation conditions: A certain type of artillery equipped with a fire control system, the fire control system is usable, the gun sight inputs are 300, 600, 900 and 1200 mils respectively, covering the gun low sight and high sight to conduct elevation angle accuracy tests, and the gun elevation angle accuracy of the fire control system is tested using the sight setter. The test results are shown in Table 5.

[0107] Table 5 Error between the gun elevation angle adjusted by the fire control system and the actual gun elevation angle

[0108]

[0109] According to Table 5, the gun elevation angle adjusted by the fire control system is almost consistent with the actual elevation angle of the gun barrel. The fire control system has a high accuracy in adjusting the gun elevation angle and can also be further corrected. The actual input sight ν of the gun is θ+000.4.

[0110] At this time, the detection and correction of the fire control gun direction angle and elevation angle accuracy are completed.

[0111] Artillery units have long relied on manual gun control, assigning firing directions using a steering wheel, calculating the gun's azimuth using a periscope, and setting the sight using a sight setter, thereby determining the gun's firing azimuth and elevation with high precision. Combining the high precision of the steering wheel, periscope, and sight setter in determining the gun's firing azimuth and elevation, and the fire control system's ability to adjust the barrel's azimuth and elevation quickly, the combination of a steering wheel, periscope, and sight setter solves the problem of accurate fire control detection. This significantly increases the combat effectiveness of artillery units and enhances their ability to rapidly strike and withdraw.
