The present invention relates to a simulated combat training system, and more particularly, when a certain area is hit by a gun or missile, accurate calculation in real time using low-cost equipment whether a soldier or a vehicle that is located in the area is hit. The present invention relates to a method and a system for data communication between devices during simulation battle training, which is configured to perform a post hoc analysis at the same time.

In general, MILES training simulators, such as laser launchers, detectors that detect them, and detector controllers that control them, are used in simulated combat drills that fire lasers instead of true shots and, if detected, determine whether to hit them. Equipment used.

Although the Miles training using the laser having a linearity is suitable for simulating a personal weapon such as a bullet flying in a straight line, there is a problem in simulating a howitzer in which a shell such as a mortar or a grenade launcher flies in a parabola.

Therefore, in order to simulate the howitzer using the Miles equipment, the simulation of the howitzer shooting is implemented in real time by the computer during the training, and the commander and the operating personnel are trained by real-time understanding of the training situation through the computer screen provided in the operation room.

When the trainees conduct a simulated battle, the data is inputted to the situation monitoring computer in the situation room where the base station is installed to simulate real-time combat progress.

However, since this requires a process of real-time data communication between a plurality of communication terminals worn by soldiers and a situation room, a communication channel capable of using a wide bandwidth frequency is essential. In addition, in order to control between multiple channels operating at the same time, expensive base station equipment is required on the situation room side, and expensive communication modems and complicated software are required in the communication terminal, all of which result in a cost increase.

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

1 is a view showing an embodiment of the process of simulating the damage using the data broadcast of the present invention when shooting a howitzer. Briefly describing the process, the shooting data generated while performing simulated shooting on the side of the tuner 20 is transformed into analog data and then transmitted to the training situation room 100 using the voice radio 26 disposed near the firearm.

In the training situation room 100, the analog data is converted into digital data to calculate the area of damage caused by shooting, and then transmitted to each soldier through a data broadcasting transmitter and the like mounted on soldiers or vehicles (hereinafter, Called a target terminal), and each target terminal determines whether or not to hit the target terminal after receiving it.

In addition, the present invention is configured so that the post-replay of the training situation is possible by transferring the data stored by each subject terminal after the training to the training analyzer computer.

Therefore, the communication method of the present invention has a merit that it is possible to communicate between the training situation room and each target terminal only with a narrow frequency band by using a data broadcast transmitter, and can also use equipment such as an existing radio.

Hereinafter, this situation will be described in more detail for each subject.

FIG. 2 is a diagram specifically illustrating a howitzer-side situation of shooting in the above-described situation of FIG. 1.

If the howitzer shooter conducts a simulated shot by a predetermined shooting procedure during training, the shooting data such as the elevation of the barrel, the azimuth angle, the type of shot, and the shooter ID is automatically inputted through a sensor attached to the relevant howitzer 20 or Alternatively, the shooter or the controller manually inputs these values into the firearm data input means 22.

The input shooting data is digital data. However, the shooting data is modulated into an analog signal in the weapon modem 24 embedded in the tuner terminal, and then transmitted to the voice transceiver 26 attached to the weapon or possessed by a soldier near the weapon.

The voice radio 26 may be one already possessed by the unit, or in the case of a small training field, a living radio may be used, and thus no additional cost is incurred in constructing the system of the present invention.

Then, the shooting data is wirelessly transmitted from the voice radio 26 to the training situation room 100 through a predetermined frequency channel set in advance in accordance with an advance appointment with the situation room 100.

In most cases, since one altar uses a plurality of firearms, a plurality of voice radios 26 on the firearm side will also be used. If the voice radios are set to use one frequency channel, when shooting data is sent by two or more door tuners at the same time, a collision of signals may occur and shooting data transmission may fail.

However, the transmission of one frame of shooting data is completed within a few seconds, so the probability of two or more shooting data transmissions overlapping at the same time is very low, which is in fact not a big obstacle.

However, when a large number of firearms are used, such as in large-scale training over regiments, it is also desirable to appropriately increase the number of frequency channels and appropriately distribute the use channels to the plurality of voice radios 26. In this case, the number of receivers should be increased by the number of channels of the frequency used in the training situation room 100.

3 is a view showing in detail the components of the training situation room 100 of the configuration of FIG.

The voice radio 30 in the training situation room receives the shooting data signal transmitted from the voice radio 26 of the howitzer, and transmits it to the training situation room modem 31.

This shooting data signal is demodulated back into the digital signal in the training situation room modem 31 and then transmitted to the training analyzer computer 32.

The training analyzer computer 32, which has received the shooting data, uses the azimuth and elevation angles of the corresponding weapon included in the shooting data, and the center coordinates of the damaged area based on data such as a dead zone reflecting the ballistic characteristics of the simulated fired ballistics. Calculate damage area data such as and damage radius. In this case, it is also preferable to additionally input the surrounding environment data such as weather conditions of the training field input separately from the shooting data so that more realistic damage area data is calculated.

The calculated damage area data is modulated back into analog data in the training situation room modem 31, and then wirelessly transmitted to the entire training area through the data broadcasting transmitter 33.

The damage area data converted to analog is not so large that the data broadcast transmitter 33 may transmit the data at a low speed using a very narrow frequency bandwidth (narrowband).

Figure 4 shows in detail the subject terminal 200 receiving the damage area data sent from the training situation room 100.

The terminal modem 40 built in the target terminal 200 attached to the training soldier or the vehicle receives the damage area data from the data broadcasting transmitter.

Then, the terminal modem 40 demodulates the received damage area data back into digital data and transmits the demodulated data to the CPU 41 of the terminal.

On the other hand, the position receiver 42 of the target terminal 200 receives the position information about the current position of the terminal from the position transmitter 400, such as GPS and transfers it to the CPU (41).

The CPU 41 compares the received location information of the terminal with the damaged area data to determine whether the target terminal 200 is inside the damaged area by the fire of the firearm.

If it is determined that the target terminal 200 is not within the damaged area, no action is necessary. On the contrary, the CPU 41 is a hit indicator such as a speaker or a lamp worn by a trainee according to whether or not the target is hit. (43) is activated, and the shot indicator 43 accordingly generates an alarm sound or flashes the lamp so that not only the trainee himself but also the surrounding controllers and colleagues can recognize the hit.

In the conventional method, in determining such a hit, the training analyzer computer receives the shot data and the position of each hit terminal in real time, and judges the hit based on this, and wirelessly transmits the data to the hit indicator worn by each soldier. It was finally sent to indicate whether or not to be hit. Therefore, since a relatively large amount of digital data communication must be performed in real time, the system has a disadvantage in that the cost of constructing the system increases and the probability of error occurrence increases.

However, the present invention has the advantage that it is possible to configure the entire system inexpensively and efficiently by allowing the target terminal to directly perform such a screening determination and to simply perform a communication method between the training analyzer computer and the terminal through data broadcasting.

In the above, the CPU 41 determines the degree of damage that is more subtle than that of judging whether it is a simple hit, that is, the degree of damage such as death, serious injury, or minor injury (half wave, slow wave in the case of a vehicle). The visual mode and / or audio mode of the shot indicator 43 may be configured to operate in various ways. For example, if red light is emitted to the indicator, it is regarded as serious injury if yellow light is emitted and isolated from training.

On the other hand, the damage area data reception of the terminal modem 40 has a noise power according to the following formula.

 N = kTB

      Where N = noise power of the received signal, k = Boltzmann constant, T = absolute temperature,

B = receive bandwidth.

Since the terminal modem 40 performs narrowband communication with the data broadcasting transmitter 33 as described above, the reception bandwidth B is very small, and accordingly, the noise power N is also greatly reduced.

As a result, the target terminal 200 of the present invention for narrow-band communication has very high sensitivity, so that the radio wave shadow area in the training ground is reduced. For this reason, the number of repeaters required for the communication may be reduced or not used at all, thus greatly reducing the overall system configuration cost.

In addition, when the terminal modem is a reception-only wireless data modem, it is helpful to reduce the size and weight of the terminal.

In the case of a vehicle or other equipment, it is natural that a damage controller can be simulated in the above manner using a detector controller and a terminal installed in the vehicle.

In the above, an embodiment of a process of simulating the damage by using the data broadcast of the present invention when the firearm is fired has been described. Now we will describe one embodiment of how a training analyzer computer collects training history records stored in a terminal possessed by soldiers after the training ends.

For reference, the data collection method or post replay process described below is not applicable only to the subsequent embodiments of the howitzer described above, but a general combat training simulation system using only a direct fire machine or a combination of a direct fire machine and a howitzer is used. Applicable to all.

FIG. 5 illustrates another embodiment of a configuration of a target terminal for data collection, and since the configuration is different from that of the target terminal of FIG. 4, the two will be described separately.

In FIG. 5, the CPU 54 of the target terminal 500 mounted by the soldiers or the vehicle periodically reads the position coordinates and the current time from the position receiver 52 during the simulation training, and stores them in the history recording storage device 50. Record this.

In addition, the CPU 54 records the event occurrence time and the position information at the time when the subject is hit or when an event important to the training outside the hit occurs, in the history recording storage device 50. At this time, the damage determination (injury, serious injury, death, etc.) for the hit may be made, and the damage determination may be recorded and stored together.

After this process, when the training is over, the control officers gather the trained soldiers in the gathering area near the situation room. When the set of trainers is completed, the controller inputs to the training analyzer computer 55 that all are gathered at the gathering place, and the training analyzer computer 55 transmits a transmitter for notifying the end of training message, that is, a short range wireless transceiver 59 or a data broadcast transmitter ( 57) and transmits to the target terminal 500 of each soldier.

Although it is advantageous to use the data broadcasting transmitter 57 as the transmitter for transmitting the training termination message in the above rather than the short range wireless transceiver 59, it is advantageous that the trainees are gathered within 100M near the control room. Even if used, there is no big difference.

When either of the two transmitters wirelessly transmits the training termination message, the terminal modem 51 built in the target terminal 500 possessed by the trainees gathered at the gathering place receives this message and demodulates the CPU 54. To pass.

The CPU 54 receives the training end message and then activates the short range radio transceiver 58 of the target terminal which is in the inactive state during the training or operated in the short range wireless communication mode with the launcher or the helmet within 1 meter. Wait until the analyzer computer 55 calls its ID.

The training analyzer computer 55 uses the short range wireless transceiver 59 to request data transmission while sequentially calling a target terminal worn by each soldier according to a predetermined algorithm.

When its ID is called through the short range wireless transceiver 58, the CPU 54 of the target terminal reads the previously recorded training history data from the history recording storage device 50, and then the short range wireless transceiver 58 And the short distance wireless transceiver 59 of the training situation room to transmit this data to the training analyzer computer 55.

The training analyzer computer 55 sequentially calls all subject terminals and reads the training history data in the same manner as described above to collect and store the training history data recorded in all terminals in the gathering place.

After this process, the training analyzer computer 55 collects all the event data such as the position coordinates and the hits of the soldiers at regular time intervals, and uses them to reconstruct the movement trajectories of the soldiers within the GPS error range. You can reproduce the occurrence. In addition, the training analyzer computer 50 may generate various statistical data such as damage rates of allies and opposing forces based on the collected training history data.

The "near-range" of the short range radio transceivers 58 and 59 generally refers to the extent to which all the gathering radius of the trainees can be included, for example, a distance within about 100 meters. Such a short range wireless transceiver can develop a form having an optimal short distance according to a given training situation, but considering the development cost and development period, it is small and inexpensive and existing communication developed according to global standards such as Bluetooth and Zigbee. It is also a good idea to purchase and use modules.

If the simulation combat training system is operated using the data broadcasting system of the present invention instead of the real-time communication network which increases the cost and complexity of the system and the network load, the bandwidth of the used frequency may be narrow and the communication method between the transmitter and the terminal is very simple. As a result, damage simulation of howitzer can be implemented in real time at low cost.

In addition, if the training situation data is collected by a simple communication system after the end of training using the system of the present invention rather than collecting the training situation data in real time as in the prior art, the training situation is very advantageous and simpler than the conventional in terms of cost and complexity of the system. A training simulation system can be established to enable post-replay of physicians.

Although embodiments of the present invention have been described based on the howitzer or the direct fire machine, since the embodiments of the present invention are applicable to firearms having the characteristics of a tram gun and a direct fire machine such as a tank gun or a panzer faust, the present invention is necessarily a howitzer. It is not limited to firearms as described above.
