DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shooting training apparatus, and more particularly to a means for calculating the output of a plurality of shooting wave sensors arranged in the vicinity of a target so as to determine a passing position of an elastic force penetrating the target. Shooting training device.

[0002]

2. Description of the Related Art A shooting training apparatus constructed as described above is
Even when shooting away from the target and without approaching the target, the position where the elasticity passes through the target can be immediately recognized.

[0003] However, in order to accurately calculate the passage position of a bullet, it is necessary to correct the calculation as occasion demands. Conventionally, when such a correction is performed, a so-called live-fire firing test is performed in advance, and the correction is performed based on the result of the live-fire firing.

[0004]

However, there has been a problem that the conventional live-fire test can only be performed by authorized persons at a specific place due to the restrictions of Japanese law. For this reason, the shooting training device itself has to be transported to a specific place, and furthermore, a cumbersome preparation such as preparing a person who is qualified to fire a live ammunition is required.

Therefore, the present invention has been made in view of such circumstances, and the object thereof is to calculate a bullet passing position extremely easily without any troublesome preparation or the like. It is an object of the present invention to provide a shooting training device capable of realizing accurate correction of the shooting.

[0006]

In order to achieve the above object, the present invention basically enters a target by calculating the outputs of a plurality of shock wave sensors arranged near the target. In the impact training apparatus provided with a means for determining a bullet passing position, the acoustic signal generating unit is positioned, and the calculation is corrected by an output of each of the shock wave sensors that detects sound from the acoustic signal generating unit. It is characterized by having the means described above.

[0007]

According to the shooting training apparatus configured as described above, the sound generated from the sound generating unit positioned near the target can correct the calculation for finding the passing position of the bullet in place of the conventional ammunition. Will be able to do it.
Therefore, accurate correction of the calculation for determining the passage position of the bullet can be realized extremely easily without any troublesome preparation or the like.

[0008]

FIG. 1 is a circuit diagram showing an embodiment of an assault sound generator newly provided in a shooting training apparatus according to the present invention. In FIG. 1, there is a function generator 1 from which a signal composed of, for example, a sine wave having a frequency of 500 KHz is output. Here, the frequency of the signal is 5
The reason why the frequency is set to 00 KHz is that a shock wave sensor S described later is used.
This is because the respective resonance frequencies of 1, S2, S3, and S4 were matched.

The signal from the function generator 1 is amplified by an amplifier 2 and input to an acoustic signal generator 3. This acoustic signal generation unit 3
For example, by driving a piezoelectric element, the frequency is 500 KHz
To generate ultrasonic waves.

The amplifier 2 is provided with an amplifier gain control circuit 4, which can control the magnitude of the sound signal from the sound signal generator 3.

On the other hand, as shown in FIG. 2, four shock wave sensors S are located near a target and on a plane orthogonal to the target.
1, S2, S3 and S4 are arranged. That is, just before the bullet enters the target, the speed of the bullet is calculated by the time difference between the shock wave sensors S1 and S2 detecting the shock wave by the bullet, and the time difference between the shock wave sensors S3 and S4 by the time difference of detecting the shock wave by the bullet. Is calculated.

The calculation of the velocity and the passing position of the bullet is performed by a sensor output waveform delay time difference measuring circuit 5 to which respective outputs of the respective shock wave sensors S1, S2, S3, S4 are inputted.

Although not shown, the sensor output waveform delay time difference measuring circuit 5 can calibrate the calculation result based on the detected error. This calibration is performed, for example, by adjusting the comparator volume.

The acoustic signal generator 3 in each of the above-described impact sound generators is configured to be positioned at the sound source generating position 10 in FIG. The shock training apparatus configured as described above has a sensor output waveform delay time difference measurement circuit 5.
Can be corrected by driving the impact sound generator shown in FIG.

That is, the shock wave sensors S1, S2, S
When an ultrasonic wave is emitted from the acoustic signal generating unit 3 disposed near S3 and S4, each of the shock wave sensors S1, S2, S3 and S4 that resonates at the frequency of the ultrasonic wave can detect the ultrasonic wave. become. Then, each of the shock wave sensors S1, S
The detection of the ultrasonic waves in 2, S3, and S4 causes a time lag of Δt1, Δt2, and Δt3, as shown in FIG.

Therefore, the location of the acoustic signal generator 3 can be calculated from these time lags. However, since the location of the acoustic signal generator 3 is known in advance, the calculation error is also known. Become like Therefore, the sensor output waveform delay time difference measurement circuit 5 can be corrected based on the calculation error.

According to the embodiment described above, the sound generated from the sound generator 3 positioned near the target is used to correct the calculation for finding the passing position of the bullet in place of the conventional ammunition. Will be able to Therefore, accurate correction of the calculation for determining the passage position of the bullet can be realized extremely easily without any troublesome preparation or the like.

In the above-described embodiment, the case where four shock wave sensors are provided has been described. However, the present invention is not limited to this, and a plurality of shock wave sensors may be used. In addition, it is a matter of course that the acoustic signal generating unit 3 may be a device that causes a discharge breakdown by using a high voltage and uses a sound generated at this time.
