Description

Technical Field

[0001] The present invention relates to the technical field of product simulation detection, and in particular to a simulation test device and a simulation test method for an initial velocity measurement device. Background Art

[0002] The measurement of the initial velocity, flight trajectory and other flight information of the projectile is one of the most basic range tests for artillery, and is also one of the basic parameters for characterizing the performance of artillery. Therefore, it is necessary to use ammunition training support monitoring equipment to accurately and timely reproduce the flight trajectory, muzzle velocity and other flight information of the rapidly flying projectiles on the vast range to researchers or observers. The initial velocity and flight trajectory of the projectile are important technical indicators for testing artillery. High-speed photography is widely used in measuring and calculating the initial velocity and flight trajectory of the projectile.

[0003] The working principle of the high-speed camera projectile initial velocity and flight trajectory detection equipment is: use a high-speed camera to monitor the muzzle status in real time. When the shell flies out of the muzzle and detects fire, a trigger signal is generated as the working signal of the high-speed camera. The high-speed camera uses a post-trigger method to complete video information acquisition; then use image recognition and tracking algorithms to calculate the projectile's initial velocity and flight trajectory.

[0004] The high-speed camera method measures and calculates the initial velocity and flight trajectory of the projectile. The initial velocity is obtained by calculation rather than direct measurement. The calculation process is affected by multiple parameters such as the installation position, pitch angle, and deflection angle of the high-speed camera. Therefore, the high-speed camera method needs to be calibrated first when measuring the initial velocity and flight trajectory of the projectile.

[0005] As a common equipment in the shooting range, the ammunition training support monitoring equipment is used frequently. In order to ensure the test accuracy, the ammunition training support monitoring equipment commonly used in the shooting range needs to be calibrated regularly. New equipment received by the shooting range usually requires joint test and calibration by both the customer and the factory.

[0006] The existing verification method is: use the ammunition training support monitoring equipment commonly used in the shooting range and the artillery for detection and calibration. When the artillery is firing live ammunition, the ammunition training support monitoring equipment commonly used in the shooting range is used to collect muzzle information to obtain the flight trajectory and initial speed of the projectile out of the muzzle.

[0007] The use of actual equipment for debugging and testing will bring great inconvenience to the debugging procedures in the development of new ammunition training support monitoring equipment, and will also be extremely inconvenient for the performance test in the manufacturing and acceptance process of ammunition training support monitoring equipment in the future; especially the actual equipment test requires the cooperation of troops, the mobilization of personnel and equipment, which takes a long time and has a large coordination surface. Therefore, it is necessary to design a projectile initial velocity simulation device for testing the tooling of new ammunition training support monitoring equipment. Summary of the invention

[0042] The muzzle velocity simulation test device of the present invention is used for performance testing during the commissioning, manufacturing and acceptance of ammunition training support monitoring equipment at a shooting range, and is particularly used for performance testing during the development process of a new generation of ammunition training support monitoring equipment developed by a manufacturer. Ammunition training support monitoring equipment is usually a high-speed camera. The working principle of using a high-speed camera to detect the initial velocity and flight trajectory of a projectile is as follows: a high-speed camera is arranged to monitor the muzzle state in real time. When a projectile flies out of the muzzle and detects a flash, a trigger signal is generated as a working signal of the high-speed camera. The high-speed camera is triggered by a flash pulse to complete video information acquisition; then, image recognition software and tracking algorithm software are used to calculate the initial velocity and flight trajectory of the projectile.

[0043] The high-speed camera method is used to measure the initial velocity and flight trajectory of a projectile, which requires calibration first.

[0044] For cameras using the high-speed camera method, the distance and width observed by the camera are in a certain proportional relationship from the perspective of the field of view. A large target at a long distance can be replaced by a small target of equal proportion at a close distance. The high-speed camera method uses the detection of muzzle flash as a trigger signal. During calibration, a large burst of flash is required to start and trigger the high-speed camera.

[0045] In the post-processing of high-speed camera images, image recognition and tracking algorithm software are used to calculate the initial velocity and flight trajectory of the projectile. A fast-moving target is required for calibration, and the speed and position can be adjusted.

[0046] The invention of the present invention is to use the light-emitting diode's luminous image to simulate the flash of a bullet leaving a gun, use the flashing mode of the revolving lantern and the flowing water lamp to simulate the flight of the bullet, and accurately simulate the flying speed of the bullet by controlling the flashing speed of the light. By controlling the lighting position of the flowing water lamp, the flight trajectory of the bullet is simulated.

[0047] The monitoring equipment for ammunition training and support includes collecting the flight trajectory and initial velocity of the projectile out of the muzzle for muzzle information. If there is no tooling, all actual equipment is used for debugging and testing, too many personnel and equipment are mobilized, the entire test takes a long time, and too many aspects need to be coordinated. It will bring great inconvenience to the debugging workers in the development process and the performance tests in the future manufacturing and acceptance processes. The muzzle initial velocity simulation test device of the present invention. It has the functions of muzzle flash simulation and projectile initial velocity simulation; the simulation speed range for the shell includes 30m / S, 100m / S, 500m / S, 1000m / S, and 2000m / S; the initial velocity of the shell can be manually selected. The visual simulation length of the initial trajectory of the muzzle is 3m, and the simulation test device is all supported by a tripod and supports folding and storage.

[0048] The muzzle velocity simulation test device of the present invention adopts light emitting tube (LED) light to form a marquee effect to simulate the muzzle flash and the trace of the projectile flight path during shooting, and realizes the speed simulation function of 30m / S, 100m / S, 500m / S, 1000m / S and 2000m / S by setting the moving flashing speed of the LED marquee.

[0067] Preferably, the projectile initial velocity simulation module is composed of 54 groups of LEDs, each group of LEDs includes 7 horizontally arranged strip-shaped LEDs, and the size of the evenly distributed strip-shaped LEDs is 1 / 18 meter. Since each SM16703 provides three groups of LED control interfaces, the entire initial velocity simulation module has a total of 18 SM16703s and 54 groups of LEDs. Each group of LEDs is arranged horizontally in sequence. The light-emitting tube LED driving unit is composed of multiple SM16703s, which are used to drive the first light-emitting tube LED display screen and the second light-emitting tube LED display screen respectively.

[0081] Step 4: the MCU completes the specified operation procedure and returns to step 2.

[0082] The working principle of the muzzle flash and initial velocity simulation device is as follows: Figure 2As shown, the muzzle flash simulation module display screen with a large surface area is installed at the front end, which is used to simulate the flash. The light time of the muzzle flash simulation module display screen is less than or equal to 50ms, and its flash time length is determined by the program pre-stored in the memory. The MCU receives the input instruction to select the simulation program of the corresponding equipment. The flash time of the high-speed cannon is short, and the flash time of the low-speed recoilless gun or howitzer is slightly longer. The corresponding flash time is pre-stored in the simulation program of the specified equipment. The projectile initial velocity simulation module has 54 display screens, which are connected in sequence. Each driver chip SM16703 can drive three LEDs. Each LED can contain 7 high-brightness LED lights when using a 24V DC power supply, so a total of 18 SM16703 and 54 groups of LEDs are required. Of course, more cascaded LED display screens can be added as needed.

[0083] After booting and initialization,

[0084] All LEDs of the muzzle flash and projectile initial velocity simulation modules are in the off state; then according to the input command, first, the muzzle flash LED lights up and then goes out; the projectile initial velocity LED display screen 1 lights up for a specified length of time, time unit: ms, and then goes out; the LED display screen 2 lights up for a specified length of time and then goes out; ... the projectile initial velocity LED display screen 54 lights up for a specified length of time and then goes out, and then goes out; according to the projectile initial velocity, the lighting time of the LED display screen corresponds to the projectile initial velocity, and the aforementioned muzzle initial velocity simulation test device design calculation table can be referred to.

[0085] By adjusting the lighting time of LED1 to LED54, the initial velocity of the projectile of 30 to 2000 m / s can be simulated.
