Bullet counting system

Abstract

The invention discloses a bullet counting system, and relates to the technical field of bullet counting. The bullet counting system comprises a sound sensor, an accurate amplification circuit, a single chip microcomputer, a communication interface circuit and a background computer, wherein the sound sensor is connected with the accurate amplification circuit through a sensor interface in a foreground computer; the accurate amplification circuit is connected with the communication interface circuit through the single chip microcomputer; the communication interface circuit is connected with theRS485 interface of the background computer through a transmission line; the background computer extracts the characteristic value of a gunshot signal through a digital filtering technology, so that non-gunshot interference is eliminated; bullet management software is built in the background computer, and used for managing getting, consumption and recovery for bullets; and an open interface is adopted for the bullet management software. According to the bullet counting system disclosed by the invention, influence on the normal shooting of a gun is avoided through non-contact installation with the gun, so that the accuracy of bullet counting can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of bullet counting, in particular to a bullet counting system. Background technique [0002] Existing bullet counting technology is not a bullet counting system in the true sense, but a bullet counter. This kind of bullet counter simply counts bullets without systematic management. [0003] Existing bullet counter mainly contains following 2 kinds of modes: 1, utilize the vibration counting of gun barrel. That is, the bullet counter is mounted on the gun barrel, and the strong vibration signal of the gun barrel is used to count when the bullet is fired. 2. Use Hall sensor to count. That is, the bullet counter is installed on the gun barrel, and the electromagnetic induction signal caused by the Hall sensor when the bullet is fired in the gun barrel is used for counting. [0004] The common disadvantages of the above methods are as follows: 1. The bullet counter must be mounted on the gun barrel, which ch...

Problems solved by technology

[0004] The common disadvantages of the above methods are as follows: 1. The bullet counter must be installed on the barrel, which changes the weight and structure of the gun body and affects the normal shooting experience

2. There must be a battery inside the counter, so the battery must be replaced or charged

3. It is not conducive to the system management of bullets
