[0002] A mortar is a short-barreled, high-angle, high-trajectory smoothbore artillery that uses a base plate to bear recoil and is mostly muzzle-loaded (small and medium calibers use muzzle loading, large calibers use tail loading) and fires finned projectiles. It has a low initial velocity, a curved trajectory, and is mainly a curved-fire artillery. It has a short barrel, a short range, and is light and flexible. Mortars can fire at targets behind cover.

[0003] However, in the existing loading process, since a large amount of ammunition is fired at one time during combat or training, the noise generated is mixed and dense. When the gunner does not fire the ammunition during loading due to other reasons, it is easy to be affected by the sound of artillery fire from adjacent gun positions, resulting in misjudgment and repeated loading, which poses a safety risk.

The bracket 306 is arranged longitudinally, and two blocks 307 are fixedly connected to the outside of the bracket 306 in opposite directions, and an observation window 308 is embedded in the bracket 306. A groove is provided at the top of the panel 3, and an on-off switch 310 is fixedly connected inside the groove. The transverse groove between the bracket 306 and the panel 3 is connected by a spring rod 309. The top surface height of the on-off switch 310 is lower than the height of the panel 3, and is located directly below the observation window 308 fixedly connected to the bracket 306, and the bracket 306 and the observation window 308 together constitute a shielding structure for the on-off switch 310.

[0026] Among them, the splint 104 is an arc-shaped structure, and the inner wall of the splint 104 is provided with grooves in an arc-shaped array, and the grooves are used for anti-slip, and the main body of the limit rod 102 is a screw structure, and there are two limit rods 102, which are installed oppositely at the front and rear sides of the ring 101, and the interface 203 set on the right side of the battery 202 is used to supply power to the inside of the battery 202, and the vibration sensor 205 is used to detect the vibration of the barrel 1.

[0027] Among them, the main body of the knob 103 is a cylindrical structure with grooves in a ring array on the outer surface, and the diameter of the knob 103 is larger than the diameter of the limit rod 102. The display screen 304 is used to display the number of firings, and the display screen 304 is electrically connected to the control board 204 fixedly connected to the shell 2.

[0028] When in use, during mortar training, when it is necessary to monitor the loading status, the ferrule 101 can be sleeved to the outer side of the barrel 1, and the limit rod 102 can be rotated by holding the knob 103 fixedly connected to the outer side of the limit rod 102, and the clamping plate 104 can be pushed by the limit rod 102 to clamp the barrel 1;

In addition, during the loading and firing of shells, the vibration sensor 205 arranged on the top surface of the control board 204 can be used to monitor the vibration of the barrel 1. The working principle of the vibration sensor 205 is to use piezoelectric materials (such as quartz, barium titanate, etc.) as sensitive elements. When the object to be measured vibrates, the piezoelectric material is subjected to pressure or tension, and its internal lattice structure is deformed, resulting in changes in the surface charge distribution, thereby generating an electrical signal. This electrical signal is proportional to the vibration parameters of the object to be measured (such as acceleration, displacement, etc.). Therefore, the vibration of the barrel 1 to be measured can be inferred by measuring the electrical signal to determine whether there are shells inside the barrel 1, and the number of firings can be synchronously fed back to the display screen 304 for display;

[0030] When in use, the bracket 306 can be compressed toward one side of the spring rod 309, and the observation window 308 on the bracket 306 will open with the bracket 306, and the on-off switch 310 will be exposed to the outside. At this time, the control board 204 can be activated by pressing the red on-off switch 310 and the system self-check indicator light will light up after waiting for 3 seconds (green for normal, red for fault). When the loading light 303 turns green, ammunition can be loaded normally. If it is red, loading is not allowed. The status of the gun barrel should be carefully checked. The system reset button 305 is used to reset the status of the detection device.
