Description

TECHNICAL FIELD [0001] The present invention relates to an impact point detection system,

Embodiments of the present invention relate to impact point detection systems and methods of their implementation.

The shell is a military firepower explosion that is fired from the shell launcher and blows toward a long distance target with the pressure of the combustion gas generated by the propellant charge of the shell launcher.

Generally, the amount of propellant used and the amount of combustion used in the shell launcher are increased to extend the range of the shell by the pressure of the combustion gas in the shell launcher. The development trend of these shells is achieved by attaching various devices to the shells or improving the shells in order to strike the target farther away to be more accurate.

On the other hand, the self-propelled artillery is one of the long-range artillery firearms, which means a movable artillery that can be transported and fired on the vehicle. Such self-propelled guns are often mounted on conventional military trucks in order to reduce development costs. That is, an upper plate is installed at a predetermined height from the bottom of a loading truck of a military truck, and a self-propelled gun is mounted on the top plate, and a shell supplied to the self-propelled gun is provided in a space formed between the top plate and the bottom of the loading box.

However, it is not easy to identify the impact point of the shell after launching the shell in the case of self-propelled gun. Conventionally, an error range is calculated by checking an impact point of a first shell using a radar or an unmanned aerial vehicle (UAV), and a second shell is fired by reflecting an error range of the first shell, The error of the impact point can be corrected.

However, if the radar is disturbed or receives radio disturbance, the object can not be achieved.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining an impact point detection system according to an embodiment of the present invention. Fig. 2 is a view for explaining the shell shown in Fig. 1. Fig.

Referring to FIG. 1, the impact point detection system includes a shell launch device 100, a shell 200, and a shell launch device control unit 300.

The cannon launching apparatus 100 is a device for launching the cannon 200 toward a target under the control of the cannon launching apparatus control unit 300. For example, the shell launch device 100 may include

The shell 200 is fired by the shell launcher 100 toward the target and moves toward the target.

In one embodiment, the shell 200 may include an image capture module 210 and a wireless transmission module 220. For example, the image capture module 210 may be located at the head portion of the cannon 200, such as reference numeral 201 in FIG. 2, and may be located at the body portion of the cannon 200, And may be located within the wireless transmission module 220, such as 203. The image capture module 210 may be located in another part of the shell 200, according to an embodiment, unlike that shown in FIG.

The image capturing module 210 captures an impact point image in the course of the shell 200 being launched from the shell launch apparatus 100 and moving toward the target. The image capture module 210 provides the captured impact point image to the wireless transmission module 220.

In one embodiment, the image capturing module 210 may generate an impact point image by capturing an image of the position in accordance with the distance remained until the impact point in the course of the movement of the shell 200 toward the target.

For example, the image capturing module 210 may capture an image of the location when the distance to the impact point is less than a specific distance in the process of moving the shell 200 toward the target. In another example, the image capturing module 210 may not capture an image if the distance to the impact point is greater than a certain distance in the course of the movement of the shell 200 toward the target.

The wireless transmission module 220 receives the image from the image capturing module 210 and provides it to the shell launch device controller 300.

In one embodiment, the wireless transmission module 220 may wirelessly provide to the shell launcher controller 300 upon receipt from the image capture module 210.

In another embodiment, the wireless transmission module 220 may compress the image according to the size of the image received from the image capturing module 210 and wirelessly provide the compressed image to the shell launch device controller 300.

In another embodiment, the wireless transmission module 220 stores the image received from the image capture module 210 in an internal memory (e.g., SRAM, Flash memory, EEPROM, SEEPROM) So that the image stored in the memory can be wirelessly provided to the shell launch device control unit 300. For example, the wireless transmission module 220 may be ejected from the cannon 200, dropping into a small parachute, and providing an impact point image to the shell launcher controller 300, such as 201-203 in FIG. 2 have. The wireless transmission module 220 may be located at a specific portion of the body of the shell 200 as shown in reference numerals 201 to 203 of FIG. It may be located at another site.

Upon receipt of an image from the cannon 200, the cannon launch device control unit 300 generates error information to the target for the cannon 200.

In one embodiment, the cannon launch device control 300 may generate error information including the error distance to the target and the error angle by comparing the impact point and the target in the impact point image.

The shell launch device control unit 300 controls the shell launch device 100 based on the error information.

In one embodiment, the cannon launch device control 300 may control the position of the cannon launch device 100 so that the error distance in the error information is compensated. For example, when the impact point of the cannon 200 and the error distance to the target are 5 cm, the cannon launch device control unit 300 may move the position of the cannon fire device 100 by 5 cm to compensate for the impact point of the next cannon have.

In another embodiment, the shell launcher controller 300 may control the angle of the shell launcher 100 so that the error angle of the error information is compensated.

Unlike this embodiment, the shell launch device controller 300 can control the shell launch device 100 based on the element information that affects the movement of the shell. Here, the element information that influences the movement of the shell may include at least one of the weight of the shell, the wind speed of the wind, the wind direction of the wind, the resistance of the air and the density of the air.

If the air resistance does not occur during the movement process of the shell, the movement time and the movement distance of the shell can be calculated through (a) to (d) of Equation (1).

[Equation 1]

(a) x = (v_0 cos a_0) t

(b) y = (v_0 sin a_0) t - 1 / 2gt ²

(c) v_x = v_0 cos a_0

(d) v_y = v_0 sin a_0 -gt
