Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a bullet detection device for target practice, in particular, a system that not only allows the shooter to practice shooting at a target, but also allows the target device to shoot at the shooter. The present invention relates to a hit detection device for target practice in a target practice device that allows for simultaneous evacuation from enemy fire and target practice.

[Conventional technology]

Conventional bullet detection devices have a patch of light-receiving elements attached to the shooter's chest or helmet, for example, and when these light-receiving elements receive a beam of light emitted from the target device, a buzzer sounds to detect a bullet. was.

[The problem that the idea aims to solve]

With conventional bullet detection devices in which the shooter attaches a batch of light-receiving elements, it is not possible to truly detect a bullet unless the shooter has a batch of light-receiving elements attached to his/her entire body. It was practically impossible to install it. In addition, when a bullet is detected by attaching a light-receiving element to the shooter in this way, it is difficult to send a bullet signal indicating that a bullet has been fired to the training commander, which has become a hindrance to scoring in training.

The purpose of this invention is to solve the above-mentioned drawbacks, and by using a light source installed on the target device side to detect the shadow caused by the shooter's presence with a light-receiving element installed behind the target device, The object of the present invention is to provide a bullet detection device for target practice that can detect bullets and send the bullet signal to the commander.

[Means to solve the problem]

In order to achieve the above object, the bullet detection device for target practice according to the present invention includes a target device equipped with a movable target, a light source device that emits a light beam after a predetermined time as the target rises, and a light source device that emits a light beam after a predetermined time as the target rises. A screen provided with a plurality of light receiving elements that receive emitted light beams, a control device that performs elevation control of a target device, light emission timing control of a light source device, and light reception enablement control of a light receiving element provided on the screen, and the control device. and a bullet detection circuit that detects a bullet hit by a shooter based on the fact that a light receiving element capable of receiving light selected by the device is blocked from receiving the light beam emitted from the light source device; It is characterized by detecting a bullet hit based on the shooter's shadow projected on the screen of the light beam.

[Effect]

When the target of the targeting device starts to stand up, a light beam is emitted from the light source device in the direction of the shooter after a predetermined period of time after the target starts standing up. At this time, if the shooter is hidden in the shadows, the shadow of the shooter will not occur, so the light rays emitted from the light source device will be received by the light receiving element of the screen provided behind. On the other hand, when a shooter is exposed to the light beam emitted from the light source device, the light beam no longer reaches the light receiving element on the screen, and a hit signal is output from the light receiving element that the light beam did not reach. Note that if the shooter shoots down the target during a predetermined period of time after the target starts standing up until the light source device emits light, the light source device will not emit a beam of light.

An embodiment of the present invention will be described below with reference to the drawings.

〔Example〕

FIG. 1 is a layout explanatory diagram of an embodiment of a target detection device for target practice according to the present invention, and FIG. 2 shows a circuit configuration of an embodiment of the target detection portion of the target detection device for target practice according to the present invention.

In FIG. 1, reference numeral 1 denotes a target device, and a target 2 is controlled to be raised and lowered by a target control signal. And target 2 has muzzle mark 2
A is drawn. When a bullet (including live bullets, simulated bullets, and ray gun bullets) hits target 2, target 2 falls down. Since the elevation control of the target 2 based on the above uses the control of a conventional target device, a description of its configuration and operation will be omitted.

A protective wall 3 is installed just in front of the target 2.
The target 2 is not directly visible to the shooter 4.

Further ahead of the protective wall 3, a light source device 5 is installed. And in front of the light source device 5,
A defense body 6 for the shooter 4 to hide his body is installed, and a screen 7 is disposed behind the defense body 6. Light receiving elements 8 that receive light beams emitted from the light source device 5 are arranged on the screen 7, and a shadow signal is output from the light receiving elements 8 that receive the shadow of the shooter 4. As is clear from FIG. 1, the light receiving elements 8 arranged on the screen 7 are provided along the upper side of the shadow of the protection body 6 caused by the light beam emitted from the light source device 5.

The operation of the bullet detection device for target practice according to the present invention arranged as shown in FIG. , give an explanation.

In FIG. 2, 1, 5, and 8 correspond to those in FIG. 1, 10 is a bullet detection circuit, 11 is a light receiving element selection circuit, 12 is a negative circuit, 13 is an AND circuit, and 2
0 represents the control device.

The light receiving element 8, the NOT circuit 12, and the AND circuit 13 constitute a circuit that generates a shadow signal.
A light receiving element 8 that generates an output when receiving a light beam.
By connecting a negative circuit 12 to the light receiving element 8, when the light receiving element 8 does not receive the light beam, an output signal is generated in the negative circuit 12 corresponding to the light receiving element 8.
If the light emission signal input to the AND circuit 13 is currently being generated, the output signal of the NOT circuit 12 passes through the AND circuit 13. The signal passing through this AND circuit 13 is a shadow signal. That is,
The shadow signal refers to a signal generated when the light receiving element 8 does not receive a light beam even though the light source device 5 is in a light emission period (while generating a light emission signal).

The light-receiving element selection circuit 11 is a circuit that passes shadow signals of the light-receiving elements 8 arranged on the screen 7 in response to a selection signal sent from the control device 20. For example, if the shooter 4 is an expert in shooting, an adjustment for a 100% hit probability is input to the control device 20 as an input signal, and the control device 20 sends the light receiving element selection circuit 11 to the light receiving element selection circuit 11 arranged on the screen 7. A selection signal is issued that allows the shadow signals from all light receiving elements 8 to pass. Therefore, in this case, no matter which light-receiving element 8 the shadow of the shooter 4 appears on, the shadow signal passes through the light-receiving element selection circuit 11, so if the shadow of the shooter 4 is projected onto the screen 8, the hit detection circuit 10 A bullet hit signal is output from. In addition, if the shooter 4 is an average-level shooter, the control device 20 receives an adjustment of the hit probability of 50% as an input signal.
0 to the light receiving element selection circuit 11 is outputted a selection signal that allows half of the shadow signals from all the light receiving elements 8 arranged on the screen 7 to pass through. Which light receiving element 8
Whether or not to pass the shadow signals from the light receiving elements 8 is determined by an operation panel (not shown) on the commander's side. It's summery. Therefore, even if the shadow of the shooter 4 is received by a light receiving element other than the light receiving element selected by the light receiving element selection circuit 11 and a shadow signal is generated from the light receiving element, the light receiving element selection circuit 11 will not process this shadow signal. is blocked, and the bullet detection circuit 10 does not generate a bullet hit signal. In other words, the probability of being hit is lower than that of the master class mentioned above. In this way, the light-receiving element selection circuit 11 selects a target according to the hit probability adjusted according to the shooting skill of the shooter 4.
This circuit selects which light-receiving element 8 generates a shadow signal to pass through. The light receiving element selection circuit 1
1 is constituted by, for example, an AND circuit.

First, when the hit probability is adjusted from the commander's operation panel (not shown) according to the shooting skill of the shooter 4, the control device 20 determines which light receiving element 8 the shadow signal is to pass through. A selection signal is sent to the light receiving element selection circuit 11. As a result, the light-receiving element 8 that generates the shadow signal that can pass through the light-receiving element selection circuit 11 is determined.

A target control signal for raising the target 2 is sent from the control device 20 to the target device 1. This allows target 2
stands up, and the target 2 appears above the protective wall 3. After transmitting the target control signal to raise the target 2, the target device 1 side sends the control device 2
0, the control device 20 outputs a light emission signal to the light source device 5 after the predetermined time has elapsed. Light source device 5 that received the light emission signal
emits a ray of light. At this time, shooter 4, defender 6
If the shooter 4 is completely hidden behind the object, the shadow of the shooter 4 will not be projected onto the screen 7, and no shadow signal will be generated from any of the light receiving elements 8. Therefore, the bullet detection circuit 10 does not output a bullet hit signal. Furthermore, if the shooter 4 is protruding from the defense body 6 at this time, the shadow of the shooter 4 is projected onto the screen 7. A shadow signal is generated from the light receiving elements 8 arranged at the position of the shadow 9 projected on the screen 7, and the shadow signal is sent to the light receiving element selection circuit 11. When the light-receiving element selection circuit 11 is selected to pass the shadow signal of the shadow 9, the shadow signal passes through the light-receiving selection circuit 11, and the bullet detection circuit 10 outputs a bullet hit signal. On the other hand, when the light-receiving element selection circuit 11 is selected to block the shadow signal of the shadow 9, the light-receiving element selection circuit 11 blocks the passage of the shadow signal of the shadow 9, and the light-receiving element selection circuit 11 blocks the shadow signal of the shadow 9 from passing through. No hit signal is output. That is, in this case, it means that shooter 4 has not been hit.

A target control signal is sent from the control device 20 to the target device 1 to raise the target 2, the target 2 appears above the protective wall 3, and the shooter 4 is able to raise the target 2 by the time the light beam is emitted from the light source device 5 described above. When the bullet hits the target 2, a hit signal is sent from the target device 1 to the control device 20, and the target 2 falls due to the function of the target device 1.
Upon receiving the hit signal sent from the target device 1, the control device 20 immediately suppresses the generation of the light emission signal to be sent to the light source device 5.

Note that the above-mentioned predetermined time from the transmission of the target control signal for raising the target 2 of the target device 1 until the light beam is emitted from the light source device 5, that is, the shooting time, is variable within the control device 20 according to the shooting skill of the shooter 4. I'm starting to be able to do it. This firing time is instructed from the commander's control panel (not shown), and the control device 2
The set shooting time is input to 0.

The number of target devices 1 shown in FIG. 1 is not limited to one, but if a plurality of target devices 1 are lined up and the configuration is such that the standing of the target 2 is varied in various ways,
Since the shooter 4 will not be able to predict the position and timing of the rising target, the target device 1
This provides better conditions for rapid fire training than when there is only one.

In the above description, the light receiving elements 8 provided on the screen 7 are arranged in a line corresponding to the shape of the defense body 6, but the light receiving elements 8 may be arranged on the entire surface of the screen 7. At this time, before starting target practice, the light source device 5 is turned on, and in order to inactivate the light receiving elements 8 that are shaded by the defense body 6, these light receiving elements are selected in advance by the light receiving element selection circuit 11. It is sufficient if the configuration is such that the shadow signal from the source is blocked. Needless to say, the selection of the light receiving element selection circuit 11 is performed by operating an operation panel on the commander's side (not shown). When using the screen 7 in which the light-receiving elements 8 are arranged on the entire surface in this way, the shape of the defense body 6 in which the shooter 4 hides is not specified, and the defense body 6 can be changed depending on the shooter 4. Advanced training becomes possible.

[Effect of idea]

As explained above, according to the present invention, the entire body of the shooter is subject to bullets, making it practical for combat. Since the hit signal can be input directly to the fixed commander's operating equipment, it becomes convenient to compile training results.

Furthermore, by installing a plurality of target devices, it becomes difficult to predict the position of the rising target and the timing of its rising, making it ideal for rapid fire training.
