[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] It should be noted that when a component is referred to as "installed on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intermediate component at the same time.

[0026] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides an intelligent bullet counter device, which is used to realize real-time counting of muzzle ammunition consumption and real-time monitoring of muzzle angle; the intelligent bullet counter device includes: a housing 1, a barrel connecting member 2, a counting sensor 3, an attitude angle sensor 4, and a wireless transmission module.

[0027] Among them, the housing 1 includes an end cover 11, a tail cover 13, and a fixing seat 12. One end of the fixing seat 12 is connected to the end cover 11, and the other end of the fixing seat 12 is connected to the tail cover 13. It should be noted that the interiors of the end cover 11, the fixing seat 12, and the tail cover 13 are interconnected, dividing the housing 1 into three parts: the end cover 11, the tail cover 13, and the fixing seat 12. This can facilitate the disassembly and assembly of the housing 1, and at the same time, it can also facilitate the installation of corresponding components, such as the counting sensor 3 and the attitude angle sensor 4, inside the housing 1. The end cover 11 and the fixing seat 12, as well as the fixing seat 12 and the tail cover 13, can be fixed by means of threaded connection. The threaded connection has a simple structure and is convenient for loading and unloading.

[0028] It should be noted that the materials of the end cover 11, the tail cover 13, and the fixing seat 12 can all be made of black ABS material. The full name of the ABS material is Acrylonitrile Butadiene Styrene, which refers to acrylonitrile-butadiene-styrene copolymer. It is a thermoplastic polymer structural material with light weight, high strength, good toughness, and easy processing and molding, also known as ABS resin.

[0029] The barrel connecting piece 2 can be fixedly connected to the housing 1, and the barrel connecting piece 2 can be fixed to the barrel, so as to connect the housing 1 and the barrel, making the connection between the housing 1 and the barrel more reliable and stable. Thus, the ammunition counting device can better monitor the number of bullets fired by the barrel and the angle of the barrel. In this embodiment, the counting sensor 3 is fixedly connected to the end cover 11, and it is used to record the consumption of bullets fired from the muzzle in real time. The attitude angle sensor 4 is arranged inside the housing 1, and it is used to monitor the angle of the muzzle in real time. The counting sensor 3 and the attitude angle sensor 4 are arranged at intervals in the length direction of the housing 1, which can reduce the mutual interference between the two, so that the monitored data can be more accurate. The wireless transmission module is also arranged inside the housing 1, and it is used to wirelessly transmit the data monitored by the counting sensor 3 and the attitude angle sensor 4 to the host computer system in real time, facilitating the monitoring and management by the management personnel.

[0030] In some embodiments, the counting sensor 3 may be an infrared detector, specifically a lead sulfide (PbS) infrared detector. This is because when a bullet is fired, from a physical perspective, the high-temperature gas generates a weak flame during the firing process, which has the characteristics of light radiation and includes certain infrared radiation characteristics, so the muzzle flame has infrared radiation characteristics. From a chemical perspective, it is because the incompletely burned gas in the gun barrel mixes with the surrounding air and then undergoes an oxidation combustion process again. According to relevant data, there are 39% CO, 9% CO2, 17% N2O, 17% H2, etc. in the muzzle flame and muzzle blast, and in addition, there are gunpowder particles with a maximum temperature of 1600°C. Most of the infrared energy radiated by the muzzle flame is distributed in the near-infrared band and the mid-infrared band. The wavelength of the energy radiated by the oxidation of H2O is the smallest, which is 0.94μm, while the wavelength of the energy radiated by N2O is the largest, which can reach 16.96μm. When a bullet is fired, the infrared signal energy radiated by the muzzle flame is mainly concentrated in the near-infrared and mid-infrared, accounting for 86% of the total energy, and the remaining 14% of the infrared signal energy is distributed in the far-infrared and extreme far-infrared ranges. Those skilled in the art know that the duration of the mid-infrared part of the muzzle flame is about 1ms, so a lead sulfide infrared detector with a response speed of 50ms is selected. When it receives infrared light, its temperature rises, its internal resistance will become smaller, its spectral response range is 0.8 - 3.2μm, the peak response wavelength is about 2.2μm, the responsivity > 1.8×108V / W, and the detectivity > 2×108. It can extract no less than 60% of the energy signal in the target signal, ensuring the reliability of the system. The relatively high response speed can extract the infrared signal of the muzzle bullet emission in real time. When the shooter fires a bullet through the firearm, the counting sensor 3 collects the infrared information of the emission flame in real time and transmits the collected information to the master control system through the wireless transmission module. The master control system software processes the received data information and converts it into ammunition graphic information, such as the total number of firearm discharges, the amount of ammunition consumed per shot, the cumulative amount of ammunition consumed, etc., and transmits it to the display end through the wireless transmission module for display.

[0031] Further, the display can be a 10-inch tablet, meeting the normal working conditions of -20°C to +50°C, resistant to free fall from 90 cm, and internally integrated with a WIFI communication module. Of course, the display can also be other suitable models. In some embodiments, the attitude angle sensor 4 can be a nine-axis wireless transmission attitude angle measurement sensor. This nine-axis wireless transmission attitude angle measurement sensor can dynamically measure triaxial acceleration, angular velocity, angle, etc., and the measurement data is output wirelessly. In this application, only its angle measurement function is actually used. The intelligent ammunition recorder device is installed on the barrel through the barrel connector 2, and the sensor axis of the attitude angle sensor 4 is adjusted to be consistent with the firearm attitude. The angle output of the attitude angle sensor 4 is the spatial attitude angle of the firearm. After setting the basic direction and the allowable range of angle change, the information on the left-right and up-down deflection angles of the firearm muzzle can be collected and transmitted to the master control system through the wireless transmission module. The master control system software processes the received data information. After the angle exceeds the limit, an overlimit alarm instruction is issued and transmitted to the display end through the wireless transmission module. The display end gives a voice reminder to the shooter about the information that the firearm muzzle deflection exceeds the limit, and the shooter needs to adjust the firearm muzzle angle according to the voice information.

[0032] In some embodiments, an alarm, such as a buzzer, is also installed in the housing 1. When the overlimit alarm function of the firearm is triggered, the buzzer is activated for reminder.

[0033] In addition, the intelligent ammunition recorder device further includes: a main control board 5, a battery 6, and a spring 7. The battery 6 is used to supply power to the main control board 5. One end of the spring 7 is electrically connected to the negative electrode of the battery 6, and the other end of the spring 7 is electrically connected to the main control board 5. The counting sensor 3, the attitude angle sensor 4, and the alarm can all be electrically connected to the main control board 5. A conductive layer is provided on the inner wall of the housing 1, and the conductive layer can be a copper-plated layer or an aluminum-plated layer. The positive electrode of the battery 6 and the main control board 5 are both electrically connected to the conductive layer. In this way, a current loop can be formed among the battery 6, the conductive layer on the inner wall of the housing 1, the main control board 5, and the spring 7, so that the battery 6 can supply power to the main control board 5 through the inner wall of the housing 1, saving more space.

[0034] Specifically, a mounting bracket 10 with a U-shaped structure is fixedly connected to the fixed seat 12, and the battery 6 is fixedly installed within the mounting bracket 10. A sliding groove is formed on the inner wall of the fixed seat 12, and the main control board 5 is fixed to the fixed seat 12 through the sliding groove. The spring 7 is embedded on the mounting bracket 10, and both ends of the spring 7 are electrically connected to the negative electrode of the battery 6 and the main control board 5 respectively. The conductive layer is disposed on the inner walls of the fixed seat 12 and the end cap 13. A copper sleeve or an aluminum threaded sleeve electrically connected to the conductive layer is fixedly connected to the fixed seat 12, which facilitates welding a wire to the copper sleeve or the aluminum threaded sleeve for electrical connection with the main control board 5, thereby enabling electrical connection between the main control board 5 and the conductive layer. Additionally, a groove plane is designed on the outer wall of the fixed seat 12, and warning reminder captions are silk-screened to ensure the installation posture.

[0035] In some embodiments, as Figure 2 shown, a first limiting hole 111 is formed at one end of the end cap 11 close to the fixed seat 12, and a part of the counting sensor 3 is connected within the first limiting hole 111 to limit the counting sensor 3. Fixing the counting sensor 3 within the first limiting hole 111 can make the arrangement of the counting sensor 3 more stable, so that the counting sensor 3 can perform the counting work better.

[0036] In some embodiments, one side of the end cap 11 away from the fixed seat 12 is provided with a flared structure, and the caliber gradually increases in the direction from the inside to the outside of the end cap 11. Among them, the design of the flared structure on one side of the end cap 11 can expand the sensing range, which is beneficial to improving the accuracy of the counting sensor 3 in collecting information on the number of bullets fired from the muzzle.

[0037] In some embodiments, an indicator light is electrically connected to the main control board 5. A hole is formed on the fixed seat 12, and a light guide column 20 is installed within the hole. The light guide column 20 is mainly used for transmitting light, and the light guide column 20 can lead the light of the indicator light to the outside of the fixed seat 12, so as to display the power-on and communication status of the intelligent bullet counting device in real time.

[0038] In some embodiments, a second limiting port 131 is formed at one end of the end cap 13 away from the fixed seat 12. A switch seat 8 is fixedly connected to the second limiting port 131. A self-locking switch 9 is fixedly connected within the switch seat 8, and the self-locking switch 9 is used to control the on-off of the circuit between the positive electrode of the battery 6 and the conductive layer on the end cap 13. Fixing the switch seat 8 at the second limiting port 131 on the side of the end cap 13 away from the fixed seat 12 can, on the one hand, fix the switch seat 8, making the arrangement of the switch seat 8 and the self-locking switch 9 more reliable and stable, and on the other hand, make the button of the self-locking switch 9 closer to the outside of the housing 1, thus facilitating the training personnel to press the self-locking switch 9. Moreover, by controlling the on-off of the circuit between the main control board 5 and the battery 6 through the self-locking switch 9, it is more flexible and convenient to use.

[0039] In some embodiments, a first seal 30 is fixedly connected between the fixed seat 12 and the end cap 13. The first seal 30 is used to seal the gap between the fixed seat 12 and the end cap 13. Through the first seal 30, the interference between the external environment and the internal components of the housing 1 can be reduced, so that the intelligent ammunition recorder device can work more smoothly and its service life can be extended.

[0040] Similarly, a second seal 40 is fixedly connected between the end cap 13 and the switch seat 8. The second seal 40 is used to seal the gap between the end cap 13 and the switch seat 8. Through the second seal 40, the interference between the external environment and the internal components of the housing 1 can be further reduced, so that the intelligent ammunition recorder device can work more smoothly and its service life can be extended.

[0041] It should be noted that the mass of the entire intelligent ammunition recorder device is 50 ± 5 g, which is relatively light.
