Description

Simulated Engagement System and Method Against Tank

TECHNICAL FIELD The present invention relates to a simulated engagement system, and more particularly, to an anti-tank simulation engagement system and method that simulates an antitank firearm shooting at a moving target such as a tank using a laser.

In general, mock engagement training is performed using laser beams in war games, survival games, military training, and the like. Such engagement training is conducted by simulating the same battlefield effects and weapon performance as actual combat.

To simulate real combat, a launcher that fires a laser beam instead of a bullet is used and monitored using a sensing device. The equipments used in the simulation are representative training weapons such as personal firearms, common firearms, antitank firearms, anti-aircraft firearms, and laser beams that are mounted on equipment such as trainers or vehicles. There is a detector to detect this.

Simulated anti-tank firearms used in the double simulated warfare have the same firearm characteristics as the actual antitank firearms, such as range, exposure range, triggering and firing procedures, and delay time, and are designed to be detachable and attached without damage to the original firearm's prototype. do. In the case of a simulated firearm, a laser beam is fired instead of a live bullet, and only the point of view that the fired laser beam is hit when detected by the detector of the target is different from the real firearm, and all other characteristics are made the same as the real firearm.

The general antitank firearms are aimed at moving targets, and the range is also longer than the personal firearms, so the launcher of the antitank firearm is manufactured in consideration of the advantages.

Figure 1 is a schematic diagram showing the bombardment process of the actual antitank firearm, the circle on the left and the figure in the circle represents the sight and the target visible through the sight, the right side shows the shooting process from the side.

As shown in FIG. 1, in order to find and fire a bombardment tank at position B in a bombardment tank at position A, in the fire control system of the bombardment tank, the movement speed of the bombardment tank, the distance from the bombardment tank to the bombardment tank, and the flight of the shells. In consideration of the speed, the shell is fired by calculating the delay time, which is the time until the shell reaches the position of the hit tank, and the stamping delay angle formed by the position of the current hit tank and the position of the hit tank when the shell arrives. Done. Then, the shell fired from the bombing tank is directed to the B 'position while the shot tank at the B position moves to the B' position, and the hit tank is bombarded at the B 'position.

However, the actual shell speed is about 1.5km / sec and the laser speed is about 300,000km / sec. In the case of antitank simulators that use laser beam instead of the actual shell, the speed of laser beam used instead of the shell It is much faster than this, and the same firing method used in real antitank firearms does not achieve the same engagement effects as in real antitank firearms. If the simulated antitank firearm using the laser beam fires the laser beam in advance toward the position B 'by applying the delay time that is the time until the shell of the actual antitank firearm reaches the position of the hit tank. The laser beam will already pass through the target tank before it reaches the target position, so that the target tank can not be hit.

Of course, if you only consider hitting a tank, you can force it to hit a tank with a different delay time than a real antitank firearm (actually, the speed of the laser beam is very fast, so The laser beam is directed toward position B), which is different from the actual situation of using an actual antitank firearm, so it becomes meaningless in terms of engagement training.

The present invention has been made to solve the above problems, there is a technical problem to provide an anti-tank simulation system and method that can accurately simulate the firing characteristics of the actual anti-tank firearm.

Another technical problem of the present invention is to provide an anti-tank simulation engagement system and method that can overcome the problems of simulation training caused by the straightness of the laser.

The anti-tank simulation engagement system of the present invention for achieving the above-mentioned technical problem comprises: a firing means for firing a first laser beam and a second laser beam against a target; Detecting means for detecting the first laser beam and the second laser beam; And controlling whether the first laser beam and the second laser beam are fired by the firing means, reading information included in the first laser beam and the second laser beam detected by the detecting means, and firing And control means for providing the launching means with information about the code to be inserted into the first laser beam and the second laser beam.

In addition, the anti-tank simulation method of the present invention includes the steps of (a) firing a first laser beam to the target to be bombarded; (b) detecting a first laser beam reflected from said object; (c) determining whether the detected first laser beam is reflected from the object; And (d) when the reflected first laser beam is reflected from the target, firing a second laser beam to the target to determine that the target has been hit.

In the above system and method, the firing of the second laser beam is performed only when the reflected laser beam is reflected from the target, and for this determination, the first laser beam is reflected back from the target by the laser emitted from the firing-side anti-tank firearm. A timecode is inserted that contains information about how long it will take.

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

Figure 2 is a block diagram showing the overall configuration of the anti-tank simulation engagement system according to the present invention. The simulated warfare system 100 of the present invention is mounted on a real antitank firearm and the trainer commands a gun to fire a shell by operating the fire control apparatus of the antitank firearm as in the actual training, whereby the simulated warfare system according to the present invention. The laser will fire instead of the shell.

Referring to FIG. 2, the anti-tank simulation engagement system 100 controls the firing of a laser beam and receives a command from the controller 10 and the controller 10 that is in charge of controlling the entire system. ), An interface for interfacing the control unit 10 with the detection unit 30 for detecting a laser beam from the outside, the display unit 40 for notifying the damage determination result to the outside, the fire control device 60 of the actual anti-tank firearm ( 50). The control unit 10 is composed of the main control unit 12, the code generator 14 and the code analyzer 16, the launch unit 20 is a laser launcher 22 for emitting a laser beam and the laser beam to be emitted It consists of the scanner 24 which scans in a predetermined area. The detector 30 includes a reflector 32 formed of at least one reflector and at least one detector 34.

Referring to the operation of the anti-tank simulation system 100 in detail as follows.

If the shooting tank is found in the shell tank, the firing command is dropped from the fire control device 60 of the actual anti-tank firearm, and in the fire control device 60, the speed of the shooting tank, the distance from the shell tank to the shooting tank, and the flying speed of the shells. Calculated by calculating the delay time, which is the time from which the shell reaches the position of the hit tank, and the stamping delay angle formed by the position of the current hit tank and the position of the hit tank when the shell arrives. Information about the delay time is transmitted to the main controller 12 through the interface 50.

The main controller 12 sends a command to the code generator 14 to generate an identification code and a timecode for firing the first laser beam. Here, the identification code is a code for identifying the bombardment tank and is a code uniquely assigned to each bombardment tank. In addition, the time code is generated based on the delay time and represents information about the time taken for the laser emitted from the bombing tank to be reflected back to the reflector of the tank being hit. Knowing the delay time, the speed of the laser, and the speed of the shell, the time until the laser reaches the shot tank is known. When the code included in the laser detected by the detector 34 is interpreted and transmitted through the code analyzer, the main controller 12 determines whether the fired first laser beam reaches the target (the tank to be fired) correctly. And if it is determined that the first laser has reached the target, it immediately fires the second laser beam. The second laser beam should contain information about the type of bullet, ID, and trainer ID to indicate the type of shell being fired. For this purpose, the main control unit 12 passes this information to the code generator for code entry. To be created.

The code generator 14 selects various codes to be inserted into the first laser beam or the second laser beam, that is, an identification code, a time code, a bullet type ID code, and a trainer ID code based on the information transmitted from the main controller 12. It can be generated and inserted into the laser beam emitted from the laser launcher 22 of the launch unit 20.

On the other hand, for the structure of the above-mentioned code may be used Miles code (MILES: Multiple Integrated Laser Engagement System). The Miles Code is defined by MCC97 (PMT 90-S002B), which is a standard protocol for the Miles communication code structure in the United States, and FIG. 3 shows the basic structure of the Miles code.

Referring to Figure 3, the Miles code consists of 11 bits, including 6 bits with logic "1" and 5 bits with logic "0", each code having a single bit pattern. The first 3 bits of the pattern have an identifier of 110 to identify the miles code to the detector receiving the miles code. The bits of the miles code are then synchronized in time to the leading edge of the first bit of this identifier, and the leading edge of two consecutive miles code bits occurs at about 333 μsec period (3 kHz). Therefore, the time interval of one complete Miles code is 3.667 msec.

Sixteen binary samples (BIN) are resampled into 11 time slots or time slots between each bit of the miles code. The sampling frequency of the 16 BINs is 48 kHz, 16 times the tile slot period of 3 kHz. Therefore, the sampling time between BINs is 20.8 msec.

Each Miles code contains 176 sampled BINs that are equally located between the 11 basic bits. The standard code of Miles Code allows laser light pulses to appear only in BINs 1, 6, 8, and 10 of these sampled BINs, so as to include player identification (PID) of simulated engagement trainers.

By using the Miles code, information such as weapon type and type of bomb, exposure range and PID are transmitted to the laser beam, and the received detector detects the miles code to recognize the damage and evaluates the simulation result. .

Here, although the Miles code is used for generating the identification code, the time code, the coal type ID code, and the trainer ID code necessary for the present invention, this is described as using the Miles code for compatibility with the existing equipment to the above. It will be apparent to those skilled in the art that their structure is not limited to the Miles code structure only.

The laser launcher 22 oscillates the first laser beam or the second laser beam by the code information received from the code generator 14. The second laser beam may be fired immediately, but the firing of the first laser beam is caused after the delay time has elapsed. That is, the laser beam is fired after a delay time so that the laser can reach the shot tank at the same time as the shot tank is hit, such as training with an actual antitank firearm. To this end, a delay time may be transmitted from the main control device 12 to the laser launcher 22 to fire the laser beam after that time has elapsed in the laser launcher 22, and the delay time may be set in the main control device 12. After the elapse of time, the firing command may be transmitted and the laser launcher 22 may be fired without any delay.

The scanner 24 allows the first laser or the second laser, which is emitted after a delay time, to be scanned in a predetermined region. That is, one preferred embodiment of the scanner 24 is in the form of a rotating mirror located on the laser emission path, so that the laser can be scanned in a predetermined area, and the faster the rotational speed, the smaller the area the laser is scanned. do. Therefore, to ensure that the laser is scanned in a constant area irrespective of the distance to the tank, the rotation speed is increased for the remote tank (i.e., the delay time is large) and slower for the tank near the tank. To be scanned in a certain area.

The reflector 32 is for reflecting the first laser beam received at the shot tank side, and the reflected laser beam should be able to return to the fired position. Such reflectors typically use a Retro Reflector and are usually preferred to be mounted on the tank's rotating turret.

The detector 34 detects the first laser beam reflected from the reflector 32 and the second laser beam emitted from the bombardment tank, and transmits the detected signal to the main controller 12 through the code analyzer 16. Do this.

The present invention introduces a method of firing two laser beams for antitank simulation engagement training. That is, when the first laser beam is emitted from the bombardment tank and the first laser beam is reflected from the target tank, the second laser beam is emitted and the second laser beam is received at the side of the shot tank receiving the second laser beam. If it is determined to be hit. Therefore, the first laser beam is used for accurately identifying the target tank, and the second laser beam is used as the beam for bombardment information.

Hereinafter, an anti-tank simulation engagement method according to the present invention will be described with reference to FIGS. 4, 5A, and 5B. Figure 4 is a schematic diagram showing the bombardment process for anti-tank simulation engagement training according to the present invention, Figures 5a to 5b is a flow chart showing a simulation engagement method according to the present invention. 5A to 5B, the left side of the dotted line represents a process occurring at the bombardment tank side and the right side represents a process occurring at the bombardment tank side.

In the bombardment tank located in the C position, the tank of the D position is found and the aiming line is aligned to the point F using the fire control device 60 of the actual anti-tank firearm, and the firing command is directed toward the position D '(S100). As described above with reference to FIG. 2, the fire control apparatus 60 calculates a delay time and a delay angle, and transmits the delay time and the delay angle to the main control apparatus 12 through the interface 50 of the simulated engagement system. The operation for this launch is exactly the same as the operation in a real antitank firearm. The main control device 12 transmits the delay time received from the fire control device 60 to the code generator and sends a command to the code generator 14 to generate an identification code and a time code for firing the first laser beam. (S110). The code generator 14 generates an identification code and a time code to be inserted into the first laser beam based on the information transmitted from the main controller 12 (S120). Subsequently, the laser launcher 22 and the scanner 24 move the first laser beam into which the identification code and the time code are inserted by the code information received from the code generator after the delay time has elapsed to the target tank side D '. Fire and scan for (S130).

The first laser beam emitted in this way is reflected by the reflector provided on the shot tank side and returns to the bombardment tank side. However, when the tank located closer to the target hit tank is located on the path of the laser due to the straightness of the laser, the first laser may be reflected by a tank other than the target hit tank. Thus, a time code is inserted into the first laser beam to determine whether the reflected first laser beam is reflected from the target tank.

The bombardment tank side detects the first laser beam reflected after the first laser beam is emitted by the detector 34 and transmits the detected signal to the code analyzer 16 (S140). The code analyzer decodes the code included in the detected signal and transmits the decoded information to the main controller 12 (S150). The main control unit 12 extracts the identification code and the time code from the decoded information and confirms that the first laser beam emitted by the identification code has been reflected (S160). The time required for the launch to be returned is calculated (S170), and it is determined whether the calculated time coincides with the time by time code information (S180). The required time is calculated by the method of firing the pulse signal of the laser at intervals of time. For example, if the pulse of the laser is generated 10000 times per second, one pulse period is 0.0001 seconds, and the distance corresponding to one millionth of a second is 300m. Therefore, when divided into 300μsec units, an error of 1m is generated. It is 10m, which is similar to the size of the tank. Therefore, it is possible to calculate the required time by converting the number of pulses that were fired until the reflected pulse returns.

If the result of the determination matches, it is determined that the reflected first laser beam is reflected from the hit tank.

Upon confirming that the first laser beam is reflected from the target shot tank, the main controller 12 immediately issues a command to fire the second laser beam (S190). Accordingly, the code generator 14 identifies the identification code and the bullet type ID code. , Generates a trainer ID code (S200). The firing of the second laser beam is not performed by a separate manipulation of the trainer, but is automatically performed by an internal algorithm of the simulation engagement system. Thus, as in a real antitank firearm, the trainer would only perform operations for the initial one shot. Subsequently, the laser launcher 22 and the scanner 24 use the code information received from the code generator 14 to transmit the laser beam in which the identification code, the bullet type ID code, and the trainer ID code are inserted into the second laser beam. ') To launch and scan for a predetermined area (S210).

The process described above is mainly focused on the process performed at the shelling tank side. On the shot tank side, the first laser beam emitted from the bombardment tank side is reflected by the reflector 32, and the first laser beam is detected by the detector 34 to detect the angle hit by the main control device 12 and the shot portion. If the second laser beam is detected by the detector 34 installed on the side of the shot tank, the main control unit 12 determines that the target is hit, and the shot portion and the hit by the first laser beam that have already been determined are determined. The degree of damage, such as slow wave, half wave, impossibility of movement, misfire, etc., is determined by the angle obtained (S230). When the main control device 12 makes a hit determination, it transmits a command to display the fact of damage on the display unit 40 (S240). The display unit 40 displays the fact of the smoke by smoking the smoke by a lamp or by a lamp by DIFCUE (Direct / Indirect Fire CUE) which is a damage indicator which is a smoke bomb treatment device (S250).

The characteristics of the laser light used in the above simulation engagement system should basically satisfy the following conditions.

1) The wavelength of the laser light should be 900 ± 30nm at room temperature or a wavelength that guarantees interoperability.

2) The laser which is safe for human body should be used to conduct simulation engagement without damaging the gamers and equipment.

3) The human safety standard applies to the Maximum Permissible Exposure (MPE) of the Laser Eye Safety Standard (ANSI Z136.1-1993).

The specific embodiments described in the present specification so far are intended to clarify the technical contents of the present invention, and the scope of the present invention should not be construed in consultation with only such examples. It is intended to cover various modifications and variations within the spirit and scope of the following claims.

As described above, according to the antitank simulation engagement system and method of the present invention, the first laser beam is fired by the laser light reflected on the target object to be fired based on the delay time information obtained from the fire control apparatus of the actual antitank firearm.
