DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic counting device for the number of bullets fired, and more particularly, to the automatic counting of the number of bullets actually fired with a rifle during a shooting exercise. The present invention relates to an automatic counting device for the number of shot bullets.

[0002]

2. Description of the Related Art In a shooting exercise with a rifle performed in the open air, a shooter hits several bullets of a real or empty packet and moves forward, backward, or in a lateral direction. It is well known that training is practiced to repeat movement after firing or firing.

[0003] In such a shooting exercise, it is attempted to confirm how many bullets were actually shot and how many shots should actually remain by collecting a shell shell after the shooting exercise. ing. This will prevent the loss of bullets during shooting exercises and ensure thorough safety management.

[0004]

However, in the above-described shooting training in which a shooter repeatedly fires a bullet while repeatedly moving forward and backward, etc., in a shooting exercise field, the shell shell after firing the bullet is not used. Are scattered here and there. For this reason, picking up all of the cartridge cases and checking the actual number of shots would actually require a great deal of labor and attention in collecting the cartridge cases.

An object of the present invention is to provide an automatic counting of the number of shots which can accurately grasp the number of shots actually fired in a shooting exercise with a rifle, particularly a shooting exercise in which a shot is repeated while moving. It is to provide a device. As a result, security can be ensured by managing the stock of the number of bullets, and at the same time, the burden of manually counting and managing the number of bullets is not eliminated.

[0006]

According to the present invention, there is provided an automatic counting apparatus for counting the number of shots according to the present invention, comprising: gun vibration detecting means mounted on a barrel for detecting vibration of a gun at the time of shooting;
A shooting sound detecting means attached to the barrel and detecting a shooting sound of a bullet at the time of shooting, and shooting for determining whether or not a shooting has been performed based on detection signals from the gun vibration detecting means and the shooting sound detecting means. The gist of the present invention is to include a judging means and a shot bullet number counting means for automatically counting the number of shot bullets when the shooting judging means judges that a bullet has been shot.

According to the thus configured automatic counting device for the number of bullets fired, the vibration of the gun at the time of shooting is detected by the gun vibration detecting means attached to the barrel, and the shooting sound at the time of shooting is shot. It is detected by the sound detection means. Then, based on the detection signals from the gun vibration detecting means and the shooting sound detecting means, it is determined by the shooting determining means whether or not a bullet was actually shot, and it was determined that the shooting was performed by the shooting determining means. Sometimes the number of shots is counted automatically.

Accordingly, even if a bullet is repeatedly shot while moving in a shooting exercise with a rifle, the number of shot bullets is automatically counted, and the work of confirming the number of remaining bullets by collecting shell shells after the shooting exercise is performed. Will be reduced.

In this case, the shooting judging means performs the shooting of the bullet when the detection signal from the gun vibration detecting means and the detection signal from the shooting sound detecting means both exceed a predetermined threshold value. It is better to judge that it has been done.

The vibration transmitted to the gun when the rifle is fired by firing the rifle is detected by the gun vibration detecting means, and the shooting sound at that time is detected by the shooting sound detecting means. However, for example, a shooting sound when another shooter near or at a close distance shoots may be detected by the shooting sound detection means of the rifle. In this case, since the detection signal of the gun vibration detecting means is not generated unless the user has triggered the rifle, it is possible to avoid the erroneous counting of the number of shooting bullets which actually triggered the trigger.

On the contrary, the vibration of the gun may be detected by the gun vibration detecting means due to the operation when the bullet is loaded into the rifle. In this case, the shooting sound is not detected by the shooting sound detecting means. This also prevents the number of shots from being incorrectly counted.

Further, it is preferable to further include a shot bullet number display means for displaying the number of shot bullets counted by the shot bullet number counting means. By doing so, it is possible to immediately know the number of shots actually used for the exercise after the end of the shooting exercise, and the number of remaining bullets is promptly confirmed.

The automatic counting device for the number of shots according to the present invention comprises a gun vibration detecting means for detecting at least the vibration of the gun at the time of shooting, and a shooting sound detecting means for detecting the shooting sound at the time of shooting. Is attached, and a monitor that receives detection signals from the gun vibration detection means and the shooting sound detection means detects whether a bullet has been shot based on the detection signals from the gun vibration detection means and the shooting sound detection means. The gist of the present invention comprises: a shooting judging means for judging whether or not a shooting bullet has been fired, and a shooting bullet number counting means for automatically counting the number of shot bullets when it is judged that a bullet has been shot. It is.

Thus, the vibration of the gun at the time of shooting is detected by the gun vibration detecting means attached to the barrel, and the shooting sound at the time of shooting is detected by the shooting sound detecting means. The detection signal from the sound detecting means is received by the monitor, and the shooting judging means built in the monitor judges whether or not a bullet has actually been shot. When it is determined by the shooting determining means that a bullet has been actually shot, the number of shots is automatically counted by the shooting counting means.

In this case, the monitor may be mounted on the shooter's shoulder or attached to the hip. In this case as well, the shooting determination means performs the shooting of the bullet when both the detection signal from the gun vibration detection means and the detection signal from the shooting sound detection means exceed a predetermined threshold value. The monitor may further include a shot bullet number display means for displaying the number of shot bullets counted by the shot bullet number counting means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a view showing an appearance of an example in which an automatic counting device for the number of shot bullets according to an embodiment of the present invention is attached to a rifle. The rifle 10 sequentially loads the bullets stored in the magazine 16 into a chamber (not shown), and when the trigger 14 is triggered by the shooter 12, the bullet of the bullet loaded in the chamber is fired from the muzzle through the barrel 18. A jig 20 for attaching an acceleration sensor 22 and a sound wave sensor 30 such as a condenser microphone is detachably attached to the tip of the barrel 18.

The acceleration sensor 22 detects the vibration of the gun based on the recoil at the time of shooting with a bullet.
It is detachably attached to the rifle 10 via the sensor attachment jig 20 and a signal cable 26a, and an acceleration detection signal of the vibration of the gun is transmitted to the monitor 28. On the other hand, the sound wave sensor 30 detects a shooting sound at the time of bullet shooting, is also detachably attached to the rifle 10 via the magnet 24 and the sensor attachment jig 20, and is provided with a signal cable 26b. The detection signal is transmitted to the monitor 28.

The monitor 28 performs predetermined signal processing on both the detection signal of the acceleration of the gun vibration detected by the acceleration sensor 22 and the detection signal of the sound wave of the shooting sound detected by the sound wave sensor 30 so that the bullet is shot. It is determined whether or not shooting has been performed. If it is determined that the bullet has been fired, the number of shots is automatically counted, and the count at that time is displayed by the display circuit 44 (see FIG. 2). ,
This is displayed on the monitor 28.

Further, since the monitor 28 is provided with a shoulder belt or a fixing member having fixing means (not shown), the monitor 28 can be hooked on the shoulders of the shooter 12 or fixed to the waist. It is designed to be carried and used. Therefore, the count of the number of shots can be confirmed by the shooter 12 at any time.

It is to be noted that the display value of the count of the number of shot bullets is reset to zero by turning on / off a power switch (not shown) provided on the monitor 28 or pressing a reset switch.

FIG. 2 is a system block diagram of an automatic counting device for the number of bullets according to an embodiment of the present invention. The sensor unit for detecting the vibration of the gun and the shooting sound is constituted by an acceleration sensor 22 attached to the tip of the barrel 18 and a sound wave sensor 30, and a counting processing unit for automatically counting the number of shot bullets, Amplifiers 36a and 36b, integration circuits 38a,
38b, comparison circuits 40a and 40b, and an AND circuit 42. A display unit for displaying the number of shots is constituted by a display circuit 44 built in the monitor 28.

The detection of the vibration of the gun in such a system configuration will be described first. The acceleration sensor 22 detects the acceleration of the recoil at the time of shooting as a detection signal of the vibration of the gun, and outputs an acceleration detection signal to the amplifier 36a. Amplifier 3
6a amplifies the acceleration detection signal to a certain level, and then outputs an amplified signal to an integration circuit 38a.
a converts the output amplified signal into a signal waveform (see FIG. 3) having one peak value for one shot.

The comparison circuit 40a determines whether the integrated acceleration detection signal is higher or lower than a predetermined threshold value and converts it into a rectangular waveform. When the acceleration detection signal is equal to or higher than a predetermined threshold, an H level signal is formed and output to the AND circuit 42. When the acceleration detection signal is lower than the predetermined threshold, an L level signal having no rectangular waveform is generated. The output is output to the AND circuit 42.

Next, the detection of the shooting sound at the time of bullet shooting will be described. The sound wave (sound pressure level) of the shooting sound at the time of bullet shooting collected by the sound wave sensor 30 is detected and an amplifier 36 is provided.
b is output as a sound wave detection signal. The amplifier 36b, the integration circuit 38b, and the comparison circuit 40b are respectively provided with the amplifier 36 described above.
a, the integration circuit 38a processes the sound wave detection signal output from the sound wave sensor 30 in the same manner as the comparison circuit 40a. Therefore, the comparison circuit 40b performs processing when the integrated sound wave detection signal is equal to or more than a predetermined threshold value. , An H level (rectangular wave) signal is formed and output to the AND circuit 42. If the signal is smaller than a predetermined threshold, the L level signal is output to the AND circuit 42 as it is.

The amplifier 36a, the integrating circuit 38a, and the comparing circuit 40a are each composed of completely the same electronic components as the amplifier 36b, the integrating circuit 38b, and the comparing circuit 40b, but are composed of completely different electronic components. It may be something. In short, it is only necessary that the detection signal be optimized within the signal processing level range.

The AND circuit 42 performs a logical operation on the acceleration detection signal output from the comparison circuit 40a and the sound wave detection signal output from the comparison circuit 40b,
This is a logical product (AND) of these (see FIG. 3), whereby only when both the vibration of the gun and the sound of the shooting at the time of the shooting exceed the respective predetermined thresholds (levels). It is to judge that there was shooting.

When the AND circuit 42 determines that a bullet has been shot in this way, it outputs an H-level signal to the display circuit 44 of the display unit. Conversely, the comparison circuits 40a, 40
If one or both of the acceleration detection signal and the sound wave detection signal output from b are L level signals, it is determined that a bullet has not been shot, and the AND circuit 42 sends the L level signal to the display circuit 44. Output.

Here, there may be a situation where the vibration of the gun caused by the operation when the bullet is loaded into the rifle 10 is likely to be determined by the comparison circuit 40a of the acceleration sensor 22, but the vibration in this case is caused by the shooting. The level is considerably lower than that of the object, and the sound wave sensor 30
The comparison circuit 40b on the side also needs to determine that the threshold value has been exceeded. Therefore, erroneous determination that shooting has occurred as a result is avoided.

In a case where a plurality of other shooters within a close range other than the shooter 12 fire at the same time, the comparison circuit 40b on the sound wave sensor 30 side easily determines that the threshold value has been exceeded. In the following, it may be considered that it is determined that the threshold value has been exceeded. However, in order to determine that the shooting by the shooter 12 has occurred, as described above, the vibration of the gun and the acceleration sensor 22 side The comparison circuit 40a also needs to determine that the threshold value has been exceeded. In this case, the comparison circuit 40
According to a, it is not determined that the threshold value has been exceeded, so that it is possible to avoid erroneously determining that a shot has occurred as a result.

The display circuit 44, when the signal for judging the presence or absence of bullet shooting output from the AND circuit 42 is at the H level,
The count is incremented by the counting operation, and the new counted value is stored in a memory area in the circuit for temporarily storing the number of shot bullets. Then, the count value obtained by counting up is displayed on the monitor 28 as a new number of shots. Conversely, when the determination signal is at the L level, the display on the monitor 28 is maintained and displayed without performing the counting operation.

Next, a description will be given, with reference to the flow chart of FIG. 4, of how the counting process at the time of bullet shooting is performed in the thus configured automatic counting device for the number of shot bullets.

First, the case where the shooter 12 continuously shoots with the rifle 10 in the shooting practice of the bullet will be described. First, the power switch of the monitor 28 is turned on by the shooter 12 and the count number displayed on the display unit is zero. Reset. When the shooting is started by the shooter 12 carrying the monitor 28, the rifle 10 is detected by the acceleration sensor 22.
Is detected (step S10, hereinafter simply referred to as “S1
0 ”), the amplification process in the amplification circuit 36a of the monitor 28, the integration process in the integration circuit 38a, and the comparison process (S12 to S14) by the comparison circuit 40a are sequentially performed.
The comparison circuit 40a of the monitor 28 determines that the acceleration detection signal is equal to or greater than the threshold (S15: “YE
S "). In other words, it is determined that the vibration of the gun has exceeded the predetermined threshold (level), whereby an H-level signal is output to the AND circuit 42 (S16).

On the other hand, in parallel with the detection of the vibration of the gun, the sound wave of the shooting sound collected by the sound wave sensor 30 is detected (S).
20) In the monitor 28, after the amplification process, the integration process, and the comparison process are sequentially performed by the various circuits on the side of the sound sensor 30 (S22 to S24), the comparison circuit 40b sets the sound detection signal to a predetermined threshold (level). ) Is determined to be the above (S25: “YES”). That is, it is determined that the shooting sound has exceeded a predetermined threshold value (level), whereby an H level signal is output to the AND circuit 42 (S26).

The logical product of the H level acceleration detection signal output from the comparison circuit 40a and the H level sound wave detection signal output from the comparison circuit 40b is determined by the AND circuit 42 to be H level ( S30: “YE
S)), the number of shot bullets is counted up from “0” to “1” by a counter circuit (not shown) built in the monitor 28 which counts the number of shot bullets, and the display circuit 44 counts up a new count value. "1" is displayed (S
31).

Thereafter, if a new shot is made (S3
2: “YES”), the routine from the measurement of the vibration of the gun (S10) and the measurement of the shooting sound (S20) is started again, and the number of shot bullets is counted up in the same manner as described above. By repeating these series of routines,
Automatic counting of the number of shots after the first shot is performed in order. At this time, the shooter 12 performs the exercise while repeating the intense movement, but the acceleration sensor 22 and the sound wave sensor 30
, It is not easily removed unless a detaching operation is performed by a predetermined method.

On the other hand, if the shooting is not continued, the shooting is terminated as it is, and the count number displayed on the display circuit 44 is the number of shots in the shooting exercise. Therefore, the shooter 12 can confirm the count number and know the number of shot bullets accurately and temporarily. Archer 1
In the case of 2, if necessary, the monitors of each shooter can be collected while keeping the number of shots displayed on the monitor 28, so that the total number of shots can be calculated based on the number of shots displayed on each monitor. It is done on a regular basis.

Next, a case where a shooter other than the shooter 12 fires at a short distance will be described. In this case, as for the shooting sound, the comparison circuit 40b determines that the sound wave detection signal has exceeded a predetermined threshold (level) through the processing of S20 to S25, and outputs the H level signal to the AND circuit 42 as the sound wave detection signal. Occasionally occurs.

However, if the gun carried by the shooter 12 has no shooting action, the vibration of the gun is not so large, the acceleration does not reach a certain level or more, and after the processing of S12 to S14 is performed, Not more than the threshold (S
15: "NO"), the comparator 40a outputs an L level signal as the acceleration detection signal to the AND circuit 42 (S18). Therefore, the logical product of the acceleration detection signal and the sound wave detection signal becomes L level (S30: “N
O "), the number of shot bullets is not counted up (S3
3) The shooting standby state (S32) is entered.

Further, even if the operation of loading a bullet into the rifle 10 causes a vibration of the gun and the vibration is detected (S10), the vibration is not the ratio of the vibration of the gun generated by the actual shooting. As in the case where another shooter other than the shooter 12 fires at a close distance, as a result, the L level signal of the acceleration detection signal is output to the AND circuit 42 by the comparison circuit 40a (S18).

Then, even if the sound of the sound wave detection signal becomes equal to or higher than a predetermined threshold value by detecting the shooting sound of the other shooter and the comparison circuit 40b outputs the H level signal to the AND circuit 42 (S26), Since the L level signal of the acceleration detection signal is output to the AND circuit 42, the logical product of the acceleration detection signal and the sound wave detection signal becomes L level (S30: "NO"), and the number of shot bullets is counted up. Is not performed (S33), and a shooting standby state (S32) is set.

The counting process in the shooting exercise of bullets is performed in this manner. For example, even in the case of collecting shell shells after the exercise, the number of shot bullets (the counting result) displayed on the monitor of each shooter's gun The collection work is estimated by summing up ()). As a result, it is possible to avoid a recovery omission and an excessive time for the recovery operation.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the acceleration sensor and the sound wave sensor for shooting detection attached to the barrel and the monitor for counting and displaying the number of shots of the bullet are connected by the signal cable. A wireless type monitoring device may be used, or a function of transferring data to a personal computer may be provided so that data processing can be performed when necessary after the exercise.

Further, in the above embodiment, the acceleration sensor and the sound wave sensor are attached by the magnet, but they may be detachably screwed, for example.

[0044]

According to the automatic counting apparatus for the number of shots of the present invention, when the detection signals from the gun vibration detecting means and the shooting sound detecting means both exceed the predetermined threshold value, the shooting judging means detects the number of shots. Since it is determined that the shooting has been performed and the number of shots is automatically counted based on this, even if the shooting is repeated while moving in the shooting exercise of the bullet, the number of bullets actually shot in the shooting exercise Can be accurately grasped. As a result, the inventory management of the number of bullets is thoroughly performed, and efficiency can be improved. Therefore, application of this to a gun is extremely useful industrially.
