Embodiment 1

[0025] Embodiment 1: The present invention is a light curtain target device that integrates sending and receiving, including a detection device, a reflection device, a timer, and a signal processing circuit. The signal captured by the detection device is connected to the timer and the signal processing circuit at the same time. The light curtain target device that combines sending and receiving includes a light curtain alignment device. Both the detection device 401 and the reflection device 402 are installed on their respective mechanical structures through the angle adjustment mechanism of the same structural form. image 3 shown in the four corners of the . The detection device 401 in the light curtain target device with the combination of transmission and reception is composed of a detection body with a combination of transmission and reception, a light curtain indicating device 104, a mechanical structure of the detection device and an angle adjustment mechanism. Diaphra...

Embodiment 2

[0028] Embodiment 2: The overall structure of the device is the same as in Embodiment 1, see image 3 , the detecting device 401 and the reflecting device 402 are connected through the connecting rod 302 to form an integrated measuring light curtain. The detection device and the reflection device are connected by connecting rods to form a detection light curtain with a certain target surface. Start the light curtain alignment device, through the light curtain adjustment device, when the voltmeter of the light curtain alignment device indicates the maximum voltage value, lock the light curtain adjustment device, and the position indicated by the laser pointer is the correct position of the light curtain. . Adjust the position of the light curtain test device or the gun frame so that the shooting direction is perpendicular to the beam of the laser pointer before shooting.

Embodiment 3

[0029] Embodiment 3: The overall structure of the device is the same as that of Embodiment 1. If the test is done on the indoor target track, or the test site has other supports, the detection device 401 and the reflection device 402 are not fixed into an integral form with connecting rods, and they are respectively fixed on both sides of the target track. On the wall, or other relative brackets, adjust the device to make it aligned. With the speed-measuring light curtain target constructed by the invention, the target surface can be customized to any size, and the cost is low.

Abstract

The invention discloses a light screen device with sending and receiving functions and a test method of the light screen. A light source and a receiving light device are installed on a circuit board to form a detection device main body with sending and receiving functions, and the light is reflected by an illuminator to form a detection screen. The detection device and the reflecting device are both provided with angle regulatory mechanisms with the same structure, the angle regulatory mechanism can adjust the angle of an incidence screen and a reflecting screen to ensure the angle between two screens by cooperating with the light screen. The main light axis of the light-emitting device is ensured to be at the same plane with the main light axis of the receiving device. The light screen device has the advantages of simple structure, fewer links, small cumulative error, high measurement precision, and convenient assembling; the light screen device not only can be used for measuring the speed of a pellet, but also used for carrying out the denseness degree test and the measurement of pellet flying angle and direction; and the light screen device broadens the measurement scope of the pellet.

Description

technical field [0001] The invention belongs to the technical field of shooting range testing, and mainly relates to a light curtain target and a test method for measuring the velocity and density of flying projectiles of various calibers, in particular to a light curtain target device integrating a light source and a receiving device. Specifically, it relates to a light curtain target device and a light curtain target testing method combining sending and receiving. Background technique [0002] In the production and development of gun shells and propellants, the initial velocity of the projectile is a must-test parameter. Using four light curtain targets to form a certain formation can test the target density of the projectile. If six light curtain targets are used to form a certain In addition to the velocity density, the formation can also test the velocity vector of the projectile. In a test system with four light curtains or six light curtains, the geometric angle meas...
