Description

The invention relates to the field of monitoring the operational reliability of artillery weapons, namely the durability of the gun barrel by determining its resource based on the registration of the shot.

Currently, the shooting, on which the indicators that determine the reasons for the transfer of barrels to different categories (from 1st to 4th), as well as to the 5th (rejection), mainly depend, is controlled manually and recorded in the form (passport) per sample. The quality of such control is greatly influenced by the human factor. Therefore, the objectivity and reliability of such control in many cases is questionable. At the same time, for some artillery guns, when determining the shot, not the actual number of shots is used, but the so-called reduced shots (for example, when firing subcaliber rounds from smooth-bore guns, when firing from the D-30 howitzer, one shot on a full charge is equal to three shots on the remaining charges ). Other guns do not even have such a "primitive" differentiation of shots by assessing their effect on barrel wear.

The technical result of the claimed invention is:

- increasing the performance of registration of the shot at different rates of fire, by automating it;

- the possibility of differentiating the shot by the type of shells with the determination of their number for different propellant charges;

- summation of shots and determination of the general shot of the gun;

- elimination of errors in registration of the number of shots due to the absence of the influence of the human factor.

The required technical result is achieved by using the claimed automated recorder for shooting the barrel of an artillery gun, differentiating the shot by the type of ammunition and consisting of an electronic device and a program for an electronic device microcontroller.

A photograph of an automated recorder shot the barrel of an artillery gun, differentiating the shot by the type of ammunition, is shown in Fig. 1.

The claimed recorder is designed to count the number of shots from a 100-mm MT-12 anti-tank gun with shells: armor-piercing sub-caliber indexes BM1, BM2, BM24; cumulative index BK16 and BK16M; cumulative fragmentation index BK3; high-explosive fragmentation indices OF15 andOF35.

The recorder can be reconfigured for other artillery pieces and ammunition supplied to them.

The electronic device of the claimed recorder is shown in FIG. 2, contains: a power supply (1), an Arduino Uno microcontroller based on an Atmega 328 microprocessor (2), two-position buttons with colored LEDs on a breadboard (3), a two-line liquid crystal display with an I2C extension (4) in Fig. 1.

Achievement of the claimed technical result is ensured by the operation of the automated recorder of the shot of the barrel of an artillery gun, which differentiates the shot by the type of ammunition as follows (see Fig. 1).

The main element that detects the shot of an artillery gun is the Hall sensor, it is connected to 1 digital input of the microcontroller. The sensor is located on the stationary part of the implement, and the magnet that will act on the sensor is located on the retractable parts. When firing with the movement of the recoil parts, the magnet acts on the sensor, thereby generating a pulse at the first logic input, i.e. when it is triggered, “1” will be applied to the logic input of the first digital pin. Two-position buttons will be connected to the 2,3,4,5 digital pins (inputs), which will indicate the indexes of the shots.

The logic of the program of the microcontroller is built by 4 main blocks, each of which is active when one of the 4 buttons, denoting charges, is pressed. At the command to open fire, the type of projectile is determined, for example, "armor-piercing", the gunner presses the button on the recorder "BM", the first block is activated, on the 2 digital pin (input), since the two-position button in the pressed state is continuously supplied with a logical "1" (electrically -5 V is applied), this signal is received by the logical block AND "and" to it, the signal from the Hall sensor is also suitable. The output of the logic block "and" is supplied with "1" only when both the sensor and the button give "1", i.e. when the button is pressed and the sensor is triggered (shot), the output of the "and" block is sent to 1. Then, all logical units from the output of the "and" block are counted, written to the non-volatile memory and displayed in the appropriate place on the liquid crystal display (5) (see. Fig. 1). Recording occurs with each change in the number in the sum block thanks to the number change detector, that is, when the number changes in the sum block, a pulse is generated in the number change detector and the button is written to the memory unit 1 and displayed on the liquid crystal display (5) in the appropriate place.

Similarly, the logic works with the other three buttons that indicate the type of shot.

After changing the number in any of the 4 storages of non-volatile memory, the total counting of the shot takes place by summing up all 4 storages and writing this number to the 5th (total) non-volatile memory storage and displaying the total number to a certain place on the liquid crystal display ( 5).

The liquid crystal display (5) shows that armor-piercing subcaliber projectiles with the BM index fired 62 shots, cumulative projectiles of the BK16 index - 86 shots, cumulative fragmentation projectiles of the BK3 index - 58 shots, high-explosive fragmentation shells of the OF index and the sum of all shots at the current time was 266.

The next shot (see Fig. 1 - the indicator (6) is on) was or will be with a cumulative fragmentation projectile of the BKZ index.

The data on the fired shots by their type is recorded in the non-volatile memory built into the electronic board, which allows an unlimited amount of time to store information about the gun firing, including when the power source is disconnected.

The algorithm of the automated recorder for shooting the barrel of an artillery gun, differentiating the shot by the type of ammunition (see Figs. 3 and 4), will be considered using the example of the operation of the first channel.

When a magnetic sensor (Hall element) passes through a permanent magnet attached to the barrel of the experimental stand (see Fig. 3), a signal is generated at the output of the magnetically controlled integrated logic chip K1116KP4 (MS1) (see Fig. 4), which is compatible in level and voltage with ports of the Atmeqa 328 microcontroller.

The selected port input, for example A5, is carried out by the SI switch actuation, which is confirmed by the illumination of the D \ LED (yellow color).

When a pulse arrives at the input A5 of the Atmeqa 328 {MCI) microcontroller, according to a special program developed in C ++, one is added to the previous sum.

The choice of the desired type of propellant charge is carried out by pressing the appropriate switch (S1, S2, S3, S4) and lighting up the color diodes (D1, D2, D3, D4).

On the MC3 screen of a liquid crystal indicator (LCD) of the ND 44780 type, the sum received for the selected type of propellant charge, for example S1, and the total number of shots fired at different propellant charges for a certain period of time are displayed.

The program for the microcontroller [1] provides an objective determination of the number of shots from the barrel (shot) for different types of ammunition and charges for them, which makes it possible to take into account the effect of each shot on the barrel of an artillery gun and calculate the deviation (loss) of the initial velocity of the projectile ΔVo from the table value indicated in the Shooting Tables due to barrel bore wear.

The claimed automated recorder fired the barrel of an artillery gun, a shot according to the type of ammunition is used in the existing sample of self-propelled artillery shown in Fig. 5.

Thus, the totality of the essential features set forth in the description of the invention makes it possible to achieve the desired technical result.
