Description

System and Method for Simulated Engagement

The present invention relates to a simulation engagement system, and more particularly, to a simulation engagement system and method for simulating a howitzer such as a grenade launcher 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 equipment used in the simulation is typically a training firearm that simulates a real firearm such as a personal firearm, a common firearm, an antitank firearm, an anti-aircraft firearm, and a laser beam emitted from a training firearm mounted on equipment such as a trainer or a vehicle. There is a sensor to detect.

The simulated howitzer used in the double simulation engagement has the same firearm characteristics as the howitzer, such as the actual K-201 grenade launcher, with the same firearm characteristics as the range, exposure range, triggering and firing procedures, and firing delay time. And to be attached. In the case of training firearms, laser beams are fired instead of bullets, and only the firearms are regarded as being hit when they are detected by the target's detector. .

Meanwhile, in order to evaluate the results of the engagement training, information on the type of firearm, the ID of the launcher (PID), the type of the bullet, etc. should be inserted into the laser beam used in place of the shot in the engagement training. For this purpose, Multiple Integrated Laser Engagement System (MILES) code is used. 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. 1 is a diagram showing the basic structure of such Miles code.

Referring to Figure 1, 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 to include player identification (PID).

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. .

However, there is a problem in the simulation engagement that simulates the howitzer, using only the information included in the Miles code, which cannot simulate the exposure effect caused by the parabolic ballistic in the actual howitzer.

2 is a view for explaining the exposure range by the parabolic trajectory of the actual howitzer to explain this problem. Referring to FIG. 2, when shooting with the actual howitzer 1, a parabolic ballistic is formed and damage occurs within a certain distance from the position where the bullet falls as well as the position where the actual shot falls. That is, as shown in Fig. 1, when the bullet falls to the X position corresponding to the range, the targets B and C at a certain distance from the position also receive an exposure effect.

On the other hand, in the case of the conventional simulation copying machine using laser beams, since the laser beam is used instead of the actual bullet, the characteristic of the exposure effect is different from that of the actual one.

3 is a schematic diagram showing the firing mode and the exposure range of the laser beam of the simulated howitzer 2 according to the prior art. As shown in Fig. 3, in the conventional simulated howitzer 2, all objects (i.e., A ', B', C ', D') on the path of the laser beam are moved due to the property that the laser beam goes straight. You will be exposed to exposure. In this case, the target D 'farther away from the range can be controlled so as not to fall within the exposure range by adjusting the output of the laser beam, but the target A' closer than the target distance falls within the exposure range. There is a problem that results in a different result from the exposure of the howler.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and there is a technical problem to provide a simulation engagement system and method capable of simulating the exposure effect of an actual howitzer.

Another technical problem of the present invention is to provide a simulation engagement system and method capable of simulating the fact that the actual howitzer can adjust the range.

In a preferred embodiment of the present invention, the firing means sets the output level of the distance identification code to be smaller than the output level of the miles code. It is also preferable that the firing means inserts the distance identification code in synchronization with a sampling binary not included in the miles code.

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

4 is a block diagram showing the configuration of a simulation engagement system according to the present invention.

Referring to FIG. 4, the simulation system of the present invention includes a central controller 10, a launcher 20, a detector 30, a display 40, and a transceiver 50. The central control unit 10 performs a function of controlling each unit of the simulation engagement system 100, and includes a microprocessor 12, a memory 14, and a modulation / demodulation unit 16.

The control center 60 is provided with a transmission and reception unit (not shown) to receive the information transmitted through the transmission and reception unit 50 from the central control unit 10 to control the situation of engagement by the plurality of simulated engagement system 100. do. That is, the central control unit 10 transmits the information including the PID, exposure time, etc. of the simulated engagement performer exposed by the transmission / reception unit 50 to the control center 60.

In addition, the central control unit 10 determines whether or not the code information included in the laser detected by the detection unit 30 having a plurality of laser detectors is decoded by the modulation / demodulation unit 16. . If it is determined that it is exposed, the display unit 40 displays the fact of exposure. The display unit 40 includes a liquid crystal display (LCD), a buzzer, a light emitting diode (LED), or a combination thereof.

The launch unit 20 controls whether to emit the laser light by the central control unit 10, and in the case of a simulated engagement system that has already been exposed, the launch from the launch unit 20 is not approved by the central control unit 10.

5 is a view for explaining the configuration of the launch unit 20 of FIG.

Referring to FIG. 5, the launch unit 20 includes a launch control unit 22, an adjuster 24A, a distance identification code (D-CODE) level signal output unit 24B, and a laser. The driver 26 and the light source 28 are included.

When the effective range is adjusted by the adjuster 24A, the D-CODE level adjusting unit 24 transmits an electric signal corresponding to the D-CODE level signal outputting unit to the firing control unit 22. The regulator 24A is displayed with a scale for the effective range, so that the simulated engagement can determine the effective range by adjusting the regulator. FIG. 6: is a figure which shows an example of the regulator 24A, and has shown the regulator which has a rotary structure. It will be apparent to those skilled in the art that the structure of the adjuster 24A can be variously modified as well as rotary, button, and sliding. Referring to FIG. 6, the K-201 grenade launcher is generally known to have a range of 100-350m, and the regulator 24A has a scale in 10m units so that the engageer can adjust the effective range in 10m units by turning the knob. have.

When the effective range is determined by the regulator 24A and an electrical signal corresponding thereto is transmitted to the launch control unit 22 by the distance identification code (D-CODE) level signal output unit 24B, it is determined from the trigger device TRIGGER. Wait for the firing signal. When the firing signal is applied to the firing control unit 22, the firing control unit 22 transmits the D-CODE output level information to the laser driving circuit. Based on this, the laser driving circuit inserts the D-CODE into the Miles code to generate the light source 28. ) To fire the laser light.

The Distance Identification Code (D-CODE) is included in the Miles Code and used to represent the effective range of the simulated engagement system 100. In other words, the laser output is reduced as the laser is moved away from the light source. Using this property, if the output level of the Miles code and the distance identification code that reached the detector attached to the subject is more than or equal to the reference value at the same time, it is judged as not being exposed, and the output of the Miles code that reaches the detector attached to the subject If it is above the reference value and the output level of the distance identification code is below the reference value, it is detected as being exposed.

7 is a diagram for explaining an example where a distance identification code is inserted into a miles code. Referring to FIG. 7, 16 sampled BINs are shown between one timeslot of the Miles code. The optical pulse output of the sampling BIN appears only in the 6th and 8th BINs, and the D-CODE is displayed in synchronization with the unused 4th BIN. In FIG. 7, the pulse of the Miles code is indicated by a solid line and the pulse of the D-CODE is indicated by a dotted line. As described above, the Miles code has 16 BINs between one timeslot and a pulse is present only in BINs 1, 6, 8, and 10. The D-CODE according to the present invention is inserted at positions of unused BINs of the 16 BINs, and the number of bits to be inserted can be one or more as necessary. In addition, the D-CODE need not be inserted in synchronization with the position of the BIN, and may be inserted between the BINs. That is, as long as there is a predetermined rule, the position where the D-CODE is inserted can be recognized and extracted even if it is inserted at any position.

The output level of the D-CODE is set lower than the output level of the Miles code. The output level of the D-CODE is preferably set to 3-20% smaller than the output level of the Miles code. In a preferred embodiment of the present invention, the level of the output of the D-CODE can also be adjusted according to the effective range of the simulated howitzer. That is, when simulating engagement with the range of the simulated howitzer at a long range, the output level of the D-CODE is increased, and when the simulation is conducted based on the range, the output level of the D-CODE is reduced. Also, even in the same range, the output of the distance identification code may be different according to the angle of the simulated howitzer.

8 is a diagram for explaining a pattern detected by the simulation engagement system 100 in relation to the effective range of the miles code including the D-CODE.

The detection unit 30 has a reference value for detecting the laser light is set so that only the laser light having an output level above the reference value can be detected and detected. Therefore, since the Miles code and the D-CODE have an output level equal to or greater than the reference value in the area R1 within the effective range shown in FIG. 8, the sensor 30 is recognized as a valid signal. In this case, the central controller 10 It recognizes that the D-CODE is inserted and treats it as not exposed.

In the effective range region R2, the output level of the Miles code and the D-CODE is lower than the output level in the R1 area, but since the Miles code is above the reference value and the D-CODE is below the reference value, the detector 30 recognizes only the Miles code. In this case, the central control unit 10 treats it as being exposed.

In the region R3 exceeding the effective range, the output level of the Miles code and the D-CODE decreases than the output level in the R2 region, and both codes have a value below the reference value. Therefore, since the detection unit 30 does not recognize any code, the central control unit 10 does not perform any processing, resulting in an unexploited result.

9 is a flowchart illustrating a simulation engagement training method according to the present invention.

For convenience of explanation, the radius of damage caused by the howitzer trajectory is assumed to be a radius of 5 m from the position where the trajectory is dropped, and the effective range is 125 m as an example. The mock engager sets the effective range to 125 m using the adjuster 24A of the firing unit 20 attached to the howitzer (S110). When the effective range is set by the adjuster 24A, the D-CODE level signal output unit 24B transmits an electric signal capable of recognizing the effective range to the firing control unit 22 (S120). When the launch control unit 22 receives a trigger signal from the linked launch device (trigger), it transmits the information about the D-CODE output level and the launch command to the laser driver 26 (S130). The laser driver 26 inserts a D-CODE having the corresponding output level into the Miles code based on the D-CODE output level information transmitted from the firing control unit 10 to generate the laser light having the code information to the light source 28. Fire through another simulated engagement system 100 (S140). Of course, the output level of the D-CODE should be set lower than the output of the Miles code.

The above process relates to firing the laser light including the D-CODE and the Miles code in the firing side simulation engagement system 100.

Next, a process of determining whether or not the exposure is received by receiving the laser light in the simulation simulation engagement system 100 will be described.

When the sensing unit 30 of the simulation engagement system 100 receives the laser light including the D-CODE and the Miles code, only the signal whose output level is greater than or equal to a preset reference value is transmitted to the central control unit 10 (S150). ). The central control unit 10 determines whether the code transmitted as a valid signal from the detection unit 30 includes the D-CODE (S160), and if the D-CODE is included, determines that it is not exposed (S170). If the D-CODE is not included, it is determined whether the Miles code is included again (S180). If it is determined that the Miles code is included, it is determined that it is exposed (S190), otherwise it is determined that it is not exposed (S170).

FIG. 10 is a diagram for explaining whether or not to expose the engagement engages at the 110m, 125m, 140m to wear or attach the simulation system (100). As described with reference to FIG. 9, it is assumed that a laser light having a range of 125 m is emitted from the launch unit 20. That is, the range D is set to 125 m by the adjuster 24A of the simulated engagement system 100 and based on this, the range D information is obtained through the launch control unit 22, the laser driver 26, and the light source 28. Assume that a laser light containing a CODE and a Miles code is emitted.

The output level of D-CODE and Miles code included in the laser light decreases as it moves away from the firing side. Referring to FIG. 10, while the D-CODE maintains an output level equal to or greater than the reference value, the output level becomes less than or equal to the reference value when 120 m or longer. The Miles code maintains an output level above the reference level, but above 130m the output level falls below the reference value. Therefore, the section with the D-CODE below the reference value and the Miles code above the reference value is determined to be exposed in this section because the section is 120-130m.

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 present invention, by inserting a D-CODE having a smaller output into the Miles code included in the laser beam emitted from the simulation engagement system, it is possible to determine whether or not to be exposed according to the presence or absence of the D-CODE. It is accompanied by the effect of accurately simulating an actual howitzer with an exposure effect on an object within a certain distance from the target.

In addition, it is possible to change the range of the simulated engagement system by adjusting the output value of the D-CODE, which has the effect of simulating that the actual howitzer can adjust the range.
