Bullet shooting counter

Abstract

The utility model relates to a bullet shooting counting device, belonging to a bullet shooting counter, which comprises a single-chip microcomputer, a testing circuit of a magnetic field sensor, a power supply circuit, a keyboard circuit, a liquid crystal display circuit, a clock circuit, a communication circuit, a reset circuit, and a storage circuit. Compared with the prior art, the utility model has advantages of high reliability, precise countering, no affection on the normal shooting, and strong anti-interference performance. The utility model can be used to calculate the bullet speed in the bore of a gun, analyze the dynamical property of the bullet in the bore of a gun, and judge the technical feature of the guns, enabling the maintenance and the updating of multi counter system information with long time for continuous use.

Description

technical field [0001] The invention belongs to a bullet shooting counting device. Background technique [0002] Counting the number of shot bullets is an important way to improve the safety management of bullet use. Developing and popularizing a bullet counter with high reliability and low cost is an important means to solve the firearms training safety problems of troops and various gun-using units. The speed of bullet ejection is an important indicator for evaluating the technical state of firearms. Obtaining the flying speed of bullets through the counting device can grasp the technical state of firearms in real time and improve the monitoring level of the technical state of firearms. [0003] The counting device (CN1668888A) adopts the principle of counting by interrupting the infrared ray by the cartridge case. Because it is necessary to ensure the launch and receiving device of the cartridge case, the installation and positioning of the invention is complicated, and...

AI Technical Summary

Problems solved by technology

Due to the need to ensure the launch and receiving device of the shell case, the installation and positioning of the invention is complicated, and its installation position is on the upper part of the gun, which seriously affects the shooter's aiming

Firearm shooting frequency testing device (CN2290019Y) counts bullets based on acoustic-electric sensor and firearm velocity meter, and has high test sensitivity, but its complex circuit and high power consumption severely limit its popularization and application

The bullet counter produced by Qishiyuan Technology Co., Ltd. in Mianyang City, Sichuan Province is also designed based on the principle of measuring shock waves, but its cost is high, its reliability is low, and it does not have the prospect of popularization and application.
