Problems solved by technology

This type of equipment is very expensive, and the maintenance price is also high, and some optoelectronic equipment is even made abroad, which is expensive and not suitable for popularization, and after-sales maintenance is difficult
This kind of optoelectronic equipment needs to collect a large number of high-definition images, so the external environment becomes an important factor of influence, and it cannot be used normally in complex weather conditions, such as heavy fog and haze weather, which have a direct impact on the measurement, and the visibility of the external environment The size of the test directly affects the accuracy and reliability of its test, which has certain limitations

Embodiment Construction

[0029] Such as figure 1 As shown, the light curtain target 100 of the present invention includes an X-axis light curtain receiving device 101, a Y-axis light curtain receiving device 102, an X-axis light curtain emitting device 103, a Y-axis light curtain emitting device 104, and X-axis and Y-axis In the interlaced light curtain area formed by the transmitting device and the receiving device, when the formed beam is effectively cut off, the system will recognize the signal and process it, and the system can resist interference such as mosquitoes and fire.

[0030] The light curtain target 100 is a photoelectric conversion system, and the functions realized by the circuit include signal amplification, subsequent processing and man-machine interface operation control. The photodiode array is connected with the preamplifier circuit, further amplified by the intermediate stage amplifier circuit, and then input to the trigger circuit and the analog output circuit. The trigger circu...

Abstract

The invention relates to a laser screen target tachymeter and a ballistic trajectory capturing method, wherein the laser screen target tachymeter and the ballistic trajectory capturing method are applied to velocity measurement of a bullet. The laser screen target tachymeter is characterized by comprising a microprocessor unit, a display touch screen unit for display and operation, an X-axis laser screen transmitting unit, a laser receiving unit of an X-axis receiving laser screen, a Y-axis laser screen transmitting unit, a laser receiving unit of a Y-axis receiving laser screen and a signal processing circuit unit. The ballistic trajectory movement locus of the bullet can be traced out in the space through multiple points while velocity is measured, and compared with a ballistic trajectory measuring method in the prior art, the ballistic trajectory capturing method is low in cost, simple in principle, high in efficiency, free of influences of visibility of external environment and visual in measuring result.

Description

technical field [0001] The invention relates to a light curtain velocimeter applied to the velocity measurement of projectiles and a method for capturing the ballistic trajectory of projectiles, and belongs to the technical field of conventional weapons shooting range testing. Background technique [0002] At present, the way of light curtain speed measurement is mostly designed by infrared emitting tube and receiving tube. Each corresponding receiving tube must correspond to an infrared emitting tube. The whole system must ensure that each receiving tube is strictly aligned with the transmitting tube. The system can enter the test state, but because the infrared light is invisible to the human eye, it cannot be seen by the human eye. Only special equipment can be used for observation, and the infrared receiving tube is very directional in sensing infrared. If the infrared emitting tube is physically For the deformation of the installation structure, we cannot perform artifi...
