Description

  The present invention relates to a bullet number measuring device used for counting and managing the number of bullets fired, for example, in shooting training for firearms.

  In Japan, the use of firearms such as pistols, rifles, and rifles is strictly regulated, and strict management is also required for the actual number of ammunition used for shooting training. For this reason, in shooting training for the police and the Self-Defense Forces, for example, the number of empty shells after shooting and the number of unused bullets are counted manually, and the number of bullets used for shooting is managed based on the counted value. I have to.

However, such a conventional management method has the following problems.
(1) In order to count empty shells, a device for collecting empty shells discharged from firearms is necessary.
(2) If the sum of the number of empty shells and the number of unused bullets does not match the number of bullets distributed, management of the number of bullets becomes inaccurate because it is necessary to rely on the user's declaration to confirm the number of bullets used. Cheap.
(3) If the user does not memorize the number of bullets used at the time of reporting the number of bullets used, it cannot be confirmed whether the missed bullet is an empty shell after shooting or an actual bullet. There is a problem with safety management.
(4) Although it is possible to accurately count the empty shells at an indoor shooting range, there is a high possibility of losing the empty shells after shooting at an outdoor shooting range, and searching for lost cases is also possible. Often difficult.

  In other words, in order to prevent the loss of empty shells during shooting training, special actions must be put on firearms to restrict user behavior and prevent loss of empty shells. Adversely affects training effectiveness.

On the other hand, a system for automatically counting the number of bullets in shooting training has also been proposed (see, for example, Patent Document 1). However, this conventionally proposed system is for automatically counting the number of impacts on the target and quickly obtaining the result of shooting such as the hit rate. Since it does not always match, it is impossible to accurately manage the number of ammunition actually fired by this system.
Japanese Patent Laid-Open No. 11-142097

  As mentioned above, conventionally, counting and managing the number of empty shells and unused bullets after shooting has been relied on manually, and since empty shells are easily lost, it is possible to accurately manage the number of bullets used. Have difficulty. Also, a system that automatically counts the number of ammunition has been proposed, but because it automatically counts the number of impacts on the target, it is possible to accurately manage the number of ammunition actually fired even if this system is used. It is difficult.

  The present invention has been made by paying attention to the above circumstances, and the purpose of the invention is to always accurately determine the number of shots without relying on manpower and without providing special equipment for collecting empty cartridges.

There is no need to provide a gun, and the number of shots can always be easily and accurately counted and managed.

  In addition, by using a plurality of magnetic sensors, the slide operation amount and slide operation speed of the slide unit are detected, and whether or not a bullet is fired is determined based on these detection results. For this reason, it is possible to more accurately determine the firing of bullets by eliminating other similar events such as the maintenance operation of the slide portion.

  According to a third aspect of the present invention, there is provided a bullet number measuring apparatus used for a firearm including a firearm body and a slide portion mounted so as to slide in conjunction with a bullet firing operation with respect to the firearm body. Then, a magnetic field sensor for detecting a change in the magnetic field accompanying the slide operation of the slide part and outputting a detection signal is attached to one of the firearm main body and the slide part. Then, the slide operation state is detected based on the detection signal output from the magnetic field sensor, and the number of fired bullets is counted by determining the presence or absence of bullets based on the detection result of the slide operation state. It is configured.

  Therefore, in the third aspect of the present invention, the number of bullets fired is automatically counted each time a bullet is fired, as in the first and second aspects. For this reason, it is not necessary to manually count the number of empty cartridges and unused bullets, and it is not necessary for the user to memorize the number of fired bullets, and special equipment is provided to prevent the loss of empty cartridges. There is no need to provide a gun, and the number of shots can always be easily and accurately counted and managed.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a schematic configuration diagram showing a first embodiment of a bullet number management system provided with a bullet number measuring apparatus according to the present invention, wherein 1 is a firearm such as a rifle or a rifle, 3 is an adapter device, 4 is Each control device is shown.

  A bullet counter 2 is detachably attached to the main body portion of the firearm 1. As the mounting means, for example, as shown in FIG. 2, a mechanical fixing means using a mounting bracket 2a and a screw 2b is used. In addition, it is also possible to use a sticking means using an adhesive or a sticking means using an adhesive tape. Further, the fixed position can be arbitrarily selected as long as it does not interfere with the aiming operation or the shooting operation.

On the other hand, a bullet sensor 6 is attached to the barrel 1a of the firearm 1 (for example, the extinguisher 1b provided at the tip thereof). As the mounting means, for example, as shown in FIGS. 2 and 3, an adapter 7 for a penetration sensor is fixed to the extinguisher 1 b with a hexagon socket set screw 7 a, and is attached to the outer peripheral surface of the adapter 7 for the penetration sensor. A means for mounting the penetration sensor 6 is used. For example, as shown in FIG. 3, a threaded portion (male screw) 7c is formed on the outer peripheral surface of the adapter 7 as shown in FIG. 3, and the threaded portion 7c is attached to the outer peripheral surface of the adapter 7 for the impact sensor. This is performed by screwing a screw portion (female screw) (not shown) formed on the inner peripheral surface of the impact sensor 6. In addition, the hole 7b having a shape and a size corresponding to the hole provided in the flame extinguisher 1b is formed in the adapter 7 for the penetration sensor so as not to impair the function of the flame extinguisher 1b. Yes.
The bullet sensor 6 and the bullet counter 2 are connected via a connection cable 8. The connection cable 8 is fixed to the barrel of the firearm 1 with Velcro (registered trademark) 8a so as not to be loosened.

  By the way, the bullet sensor 6 detects the passage of bullets fired from the muzzle. For example, as shown in FIG. 8, two pairs of optical sensors DS1 and DS2 arranged at regular intervals in the direction of bullet movement are provided. Prepare. These optical sensors DS1 and DS2 are composed of light emitting diodes (LEDs) DS1a and DS2a and photo ICDS1b and DS2b.

  For example, as shown in FIG. 4, the light emitting diodes DS1a and DS2a and the photo ICDS1b and DS2b are disposed to face both side portions 6a and 6a of the impact sensor 6 with the bullet passage portion 6c interposed therebetween. The both side portions 6a and 6a are provided with transmission holes 6d and 6d having a diameter of about 1 mm in order to transmit light emitted from the light emitting diode DSa. Further, protective glasses 6b and 6b are installed between the transmission holes 6d and 6d and the light emitting diodes DS1a and DS2a and the photo ICDS1b and DS2b, respectively. These protective glasses 6b and 6b protect the light emitting diodes and the photo ICDS1b and DS2b from a flame generated when a bullet is fired.

  On the other hand, the bullet counter 2 has a box shape, and indicators 27a and 27b and a push button 29 are provided on the outer surface of the box-shaped housing as shown in FIG. The push button 29 is a button operated when displaying the operation state of the bullet number counter 2. When the push button 29 is pressed, the display 27a is controlled to light up in green, for example, in a normal operation state, and to light up in red in a state where the power supply voltage is lowered. The indicator 27b is for displaying the number of shots and the number of remaining bullets. When the count value of the number of shots reaches the initial number of bullets, the value of the number of remaining bullets is below a threshold value. When it decreases, it is controlled to turn on each.

The internal circuit of the bullet number counter 2 is configured as follows. FIG. 6 is a block diagram showing the configuration.
That is, the bullet counter 2 includes an impact sensor 21, and a signal representing the impact waveform output from the impact sensor 21 is converted into a digital signal by an analog / digital converter (A / D) 22, and then the impact waveform is detected. Input to the circuit 23. The impact waveform detection circuit 23 detects the acceleration level of the impact from the input impact waveform signal and compares the detected value with the threshold for impact determination set in the threshold setting circuit 24. As a result of the comparison, when the detected value of each acceleration level exceeds the threshold value, a count pulse is generated and supplied to the count circuit 25. At this time, when each acceleration level exceeds the threshold value and the count pulse is generated once, the shock waveform detection circuit 23 counts no matter how many times the acceleration level exceeds the threshold value for a period of ten and several milliseconds thereafter. Does not generate a pulse. This is to prevent erroneous counting of one shot as multiple times. The count circuit 25 counts the count pulses supplied from the impact waveform detection circuit 23 and outputs the count value to the control circuit 20 as the number of times of shooting in the empty package shooting training.

  The bullet count counter 2 also receives detection signals from two pairs of optical sensors DS1 and DS2 sent from the bullet sensor 6 via the connection cable 8. These detection signals are converted into digital signals by an analog / digital converter (A / D) 31 and then input to a ballistic detection circuit 32. The bullet detection circuit 32 determines whether or not a bullet has passed based on the input detection signal. At the same time, the bullet passing speed is calculated based on the detection signal, and the calculated bullet passing speed is compared with a bullet speed determination threshold set in the threshold setting circuit 24. When the passage of the bullet is detected and the passage speed is equal to or higher than the threshold value, a count pulse is generated and supplied to the count circuit 33. The count circuit 33 counts the count pulse supplied from the bullet detection circuit 32 and outputs the count value to the control circuit 20 as the number of shots in the actual shot training.

The control circuit 20 includes a condition input control unit 201, a threshold value control unit 202, a display control unit 203, and a measurement data output control unit 204.
Prior to the start of shooting, the condition input control unit 201 inputs information representing a measurement condition transmitted from the control device 4 (described later) into the ammunition counter 2 while the ammunition counter 2 is mounted in the slot 3a of the adapter device 3. The data is received via the output interface (input / output I / F) 26 and stored in the storage unit 30. The information indicating the measurement condition includes identification information (ID) of the bullet counter 2, the number of bullets carried (the number of bullets actually carried), the number of bullets set and the number of bullets set (the number of bullets set by the mission). included. Since the bullet counter 2 is associated with the type (gun type) and bullet type of the firearm 1 on a one-to-one basis, it is not necessary to set information indicating the gun type and the bullet type.

  The threshold control unit 202 includes a memory table that stores threshold values set in advance in association with gun types and bullet types. Prior to the start of shooting training, the corresponding threshold value is read from the memory table, and the read threshold value is set in the threshold value setting circuit 24.

  The display control unit 203 turns on the indicator 27b when the count value of the number of bullets output from the count circuits 25 and 33 reaches the bullet number (set bullet number) that is initially set before shooting. Further, in response to pressing of the push button 29, it is determined whether or not the output voltage value of the battery 35 has dropped below a predetermined threshold value, and the determination result is displayed on the display unit 27a with different display colors. Let

  The measurement data output control unit 204 uses the count value of the number of bullets counted by the counting circuits 25 and 33 and the value of the number of remaining bullets calculated by the display control unit 203 as the ID of the bullet number counter 2 and the carrying amount. The information is stored in the storage unit 30 in association with the number of bullets. Then, after the shooting is completed, the information stored in the storage unit 30 is input / output I / O in accordance with the data transmission request coming from the control device 4 in a state where the shot number counter 2 is mounted in the slot 3a of the adapter device 3. It transmits to the control apparatus 4 via the adapter apparatus 3 from F26.

  The input / output I / F 26 has an electric / optical conversion function, converts a signal to be transmitted to the adapter device 3 from an electric signal to an optical signal and outputs it, and receives an optical signal sent from the adapter device 3. To convert it into an electrical signal. Further, the power supply circuit 34 generates an operating voltage Vcc necessary for operating each circuit in the bullet number counter 2 based on the voltage output from the battery 35.

  The adapter device 3 is provided with a plurality of (for example, 10) slots 3a, 3a,. The bullet counter 2 is detachably mounted in these slots 3a, 3a,. The adapter device 3 performs an interface between the control device 4 and the ammunition counter 2, and as shown in FIG. 7, an input / output interface (input / output I / F) 36, a signal processing unit 37, and a serial The conversion part 38 is provided.

  The input / output I / F 36 has an electrical / optical signal conversion function, receives an optical signal sent from the bullet counter 2 and converts it into an electrical signal, and transmits a signal to the bullet counter 2 from an electrical signal to an optical signal. Convert to signal and output. The signal processing unit 37 and the serial conversion unit 38 convert the data output from the bullet number counter 2 into a format that can be handled by the control device 4, and the data sent from the control device 4 by the bullet number counter 2. Convert to a format that can be handled.

  The adapter device 3 operates by a power output supplied from the control device 4. Further, it has a function of charging the battery 35 built in the bullet counter 2 by the supplied power output. Further, the adapter device 3 is provided with inspection terminals 3b and 3b. The inspection terminals 3b and 3b are used for a continuity test of the connection cable 8.

  The control device 4 is composed of, for example, a personal computer and is connected to the adapter device 3 via a connection cable 5. As shown in FIG. 7, the control device 4 includes a CPU (Central Processing Unit), an input / output interface (input / output I / F) 43, a storage unit 44 using a hard disk or flash memory as a storage medium, and an LCD (Liquid A display unit 45 composed of a crystal display) and an input unit 46 composed of a keyboard and a mouse are connected via a bus 42. The CPU 41 executes the application program stored in the storage unit 44 to transmit information necessary for the bullet count operation to the bullet counter 2 and the count result from the bullet counter 2. A control function that collects information that represents and a function that creates a bullet number management book based on the collected information are realized. In addition, as a connection means between the control apparatus 4 and the adapter apparatus 3, an optical communication means and a radio | wireless communication means other than a connection cable can be used.

Next, the operation of the system configured as described above will be described.
(1) Setting measurement conditions
Prior to shooting, the manager of the firearm 1 inputs the measurement condition necessary for counting the number of bullets fired in the control device 4 after mounting the bullet counter 2 in one of the slots 3 a of the adapter device 3. As shown in FIG. 13, for example, the measurement condition to be input includes information representing the ID of the bullet number counter 2, the user, the firearm used, the number of bullets carried, the number of bullets set, and the date and time of use. An example of the initial input screen for the measurement conditions is shown in G1 of FIG.

  When a transmission operation of the measurement condition is performed in the control device 4 after the measurement condition is input, the ID of the bullet counter 2, the number of bullets to be carried, and the number of bullets to be set are connected via the connection cable 5. It is sent to the adapter device 3 and input from the adapter device 3 to the ammunition counter 2. The ammunition counter 2 captures the above measurement conditions into the condition input control unit 201 of the control circuit 20 via the input / output I / F 26 and stores them in the storage unit 30.

Further, when the measurement condition is stored, the bullet counter 2 gives information indicating a preset gun type and bullet type from the condition input control unit 201 to the threshold value determination unit 202. The threshold value determination unit 202 reads out the threshold value corresponding to the information indicating the input gun type and bullet type from the memory table and supplies the threshold value setting circuit 24 with the threshold value. Thus, an optimum determination threshold value corresponding to the gun type and the bullet type to be used is set.
Whether the bullet counter 2 is to be operated as the actual bullet mode or the empty packet mode is switched and set by the administrator or the user inputting in the control device 4 during the initial setting described above.

(2) Operation during shooting training
(2-1) In the case of live launch training
The user attaches the bullet counter 2 assigned to the user to the designated firearm 1 as shown in FIG. At the same time, the bullet sensor 6 is attached to the extinguisher 1 b of the firearm 1 using an adapter 7 as shown in FIG. 3, and the bullet sensor 6 is connected to the bullet counter 2 by a connection cable 8. In this state, the administrator distributes live ammunition to the gun user (trainer). The user sets the above-described distributed ammunition on the firearm 1 and starts shooting.

  The bullet counter 2 first determines whether the actual bullet mode is set as the shooting mode or the empty packet mode is set based on the mode set at the time of the initial setting. If it is determined that the actual bullet mode is set, the operation for measuring the number of shots is executed based on the detection signal of the bullet sensor 6 as follows.

  That is, when a bullet is fired from the firearm 1, as shown in FIG. 8, in the two sets of optical sensors DS1 and DS2 of the penetration sensor 6, the light emitting diodes DS1a and DS1b are connected to the photo ICDS2a and DS2b by the passage of the bullet. The light is blocked, so that a detection signal as shown in FIG. 9 is output according to the passage timing of the bullet.

  In the bullet number counter 2, when the detection signal is input, the bullet detection circuit 32 performs a detection process as follows. FIG. 10 is a flowchart showing the processing procedure. That is, first, in step S101, it is determined whether or not the bullet has passed through the optical sensors DS1 and DS2 based on the input detection signal. As a result of this determination, if no detection signal is input to either one of the optical sensors DS1, DS2, it is determined that the bullet is not fired, and no count pulse is output in step S102.

  On the other hand, it is assumed that detection signals from both the optical sensors DS1 and DS2 are input. In this case, the bullet detection circuit 32 proceeds to step S103, where it first detects the time difference Δt between the two input detection pulses, and the interval between the time difference Δt and the known optical sensors DS1, DS2. The bullet velocity is calculated from L. Next, the calculated bullet velocity L / Δt is compared with a threshold value to determine whether or not the bullet velocity L / Δt is faster than the threshold value. As a result of this comparison, if the bullet speed L / Δt is less than or equal to the threshold value, it is determined that the bullet is not fired, and no count pulse is output in step S104. On the other hand, if the bullet speed L / Δt is faster than the threshold value, it is determined that a bullet has been fired, and the process proceeds to step S105 to output a count pulse. As a result, the count circuit 33 counts the count pulses.

  Thereafter, each time a bullet is fired, the bullet passage detection circuit 32 of the bullet number counter 2 determines whether or not the bullet has passed and the bullet velocity based on the detection signal of the bullet sensor 6. When the firing of the bullet is confirmed based on the above, the count value is counted up by the count circuit 33. The count value of the count circuit 33 is taken into the control circuit 20 as the number of fired bullets each time it is counted up.

  In the bullet counter 2 during the above shooting training, the display control unit 203 displays the number of shots and the number of remaining bullets and controls the generation of alarms. That is, in the display control unit 203, the count value of the number of shots output from the count circuit 33 is compared with the set number of bullets initially set before shooting. Then, when the count value of the number of shots reaches the set number of bullets, the indicator 27b is turned on. In addition, the remaining number of bullets was calculated based on the count value of the number of fired bullets and the number of ammunition carried in advance as one of the measurement conditions, and the remaining number of bullets decreased below a preset value. Even in this case, the indicator 27b is lit. When the user depresses the push button 29 of the bullet counter 2, the display control unit 203 determines whether or not the output voltage value of the battery 35 is equal to or greater than the threshold value, and the determination result is displayed on the display 27a. Are displayed differently.

(2-2) Empty package launch training
In the case of performing the firing training by empty packaging, the shooting mode is set to the empty packaging mode in the control device 4 with the bullet counter 2 mounted in one of the slots 3a of the adapter device 3, and the number of bullets to be fired is set. Enter the measurement conditions necessary for counting. Then, the input shooting mode designation information is transferred to the bullet number counter 2 via the adapter device 3 and stored in the storage unit 30 in the bullet number counter 2. At the same time, among the input measurement conditions, the ID of the bullet counter 2, the number of bullets carried and the number of bullets set are sent to the adapter device 3 via the connection cable 5. Entered. The ammunition counter 2 captures the above measurement conditions into the condition input control unit 201 of the control circuit 20 via the input / output I / F 26 and stores them in the storage unit 30.

  When the measurement condition is stored, the bullet number counter 2 gives information representing a preset gun type and bullet type from the condition input control unit 201 to the threshold value determination unit 202. The threshold value determination unit 202 reads out the threshold value corresponding to the information indicating the input gun type and bullet type from the memory table and supplies the threshold value setting circuit 24 with the threshold value. Thus, an optimum determination threshold value corresponding to the gun type and the bullet type to be used is set.

  When the setting of the measurement conditions is completed, the user attaches only the bullet counter 2 to the firearm 1 as shown in FIG. 11, and does not attach the bullet sensor 6 to the extinguisher 1b of the firearm 1. Then, shooting starts in this state. At this time, since the empty counter mode is initially set as the shooting mode, the bullet counter 2 measures the number of shots fired based on the detection signal of the impact sensor 21 built in the bullet counter 2 as follows. Execute.

  That is, when shooting is performed, the impact generated during the shooting is detected by the impact sensor 21 of the bullet counter 2, and the detected impact waveform is converted into a digital signal by the A / D 22, and then the impact waveform detection circuit 23 Entered. In the impact waveform detection circuit 23, the acceleration level is detected from the input impact waveform, and the detected values are compared with the threshold values THa and THa ′ set in the threshold value setting circuit 24, respectively, and the presence or absence of shooting is detected. Is determined.

  For example, if an impact waveform as shown in FIG. 12 is obtained, the amplitude level of each waveform of the impact waveform is detected as an acceleration level and compared with threshold values THa and THa ′. Then, when the amplitude level exceeds the threshold value THa or THa ′, a first count pulse indicating that the acceleration level satisfies the determination condition is generated and output to the count circuit 25. At this time, if the count pulse is generated once, no count pulse is generated no matter how many times the acceleration level exceeds the threshold value THa or THa ′ in the period of ten and several milliseconds thereafter.

When the count pulse is generated from the impact waveform detection circuit 23, the count circuit 25 determines that the shooting has been performed once and counts up the count value of the number of times of shooting. That is, when the acceleration level of the first shock waveform exceeds the threshold value THa or THa ′, it is determined that the shooting has been performed once, and the count value is counted up once. The count value of the number of times of shooting is notified to the display control unit 203 and the measurement data output control unit 204 of the control circuit 20, respectively.
Thereafter, in the same manner, every time an empty wrap shot is performed, the impact is detected and determined, and the number of shots is counted up.

  In the bullet counter 2 during the above shooting training, the display control unit 203 displays the number of shootings and controls the generation of alarms. That is, every time the count value of the number of shootings notified from the count circuit 25 is counted up, the display control unit 203 calculates the remaining number of shootings from this count value and a predetermined number input in advance. When the calculated remaining number of shots becomes less than a certain number, the indicator 27b is turned on. Further, the indicator 27b is also turned on when the calculated remaining number of bullets is reduced below a preset value. Therefore, the user can recognize the end of shooting without being aware of the number of remaining bullets.

(3) Processing after the end of shooting training
When the shooting training is completed, the user removes the bullet counter 2 from the firearm 1 and hands it to the administrator. After attaching the handed bullet number counter 2 to the slot 3 a of the adapter device 3, the administrator performs an operation for collecting measurement data from the bullet number counter 2 in the control device 4. Then, a data transmission request is sent from the control device 4 to each slot of the adapter device 3 by, for example, polling, and this data transmission request is transferred to the bullet number counter 2 mounted in the slot 3a.

  In the bullet counter 2, when the data transmission request arrives, the measurement data output control unit 204 reads the count value of the number of bullets fired from the count circuits 25 and 33 according to this request. Then, the read count value of the number of fired bullets is input from the input / output I / F 26 to the control device 4 via the adapter device 3 together with the ID of the bullet number counter 2 and the number of bullets carried before the start of shooting. Send. At this time, the value of the remaining number of bullets calculated by the display control unit 203 may be transferred to the control device 4 together with the number of shots and the like.

  The control device 4 receives the measurement data sent from the bullet counter 2, that is, the count value of the bullet number, the ID of the bullet counter 2, and the value of the ammunition number, and stores them in the storage unit 44. At the same time, the remaining number of bullets is obtained by comparing the count value of the number of fired bullets and the number of carried bullets with the value stored before shooting, and the remaining number of bullets is calculated as the count value of the number of fired bullets and the number of carried bullets. A list is displayed together with the number on the display unit 45. An example of the display result is shown in G2 of FIG. Therefore, the administrator can confirm at a glance the gun type, the number of bullets carried, the number of bullets fired, and the number of remaining bullets for each user from the displayed count measurement result information.

  The control device 4 creates a bullet number management book at an arbitrary timing based on the stored measurement data, and stores it in the storage unit 44. This ammunition number management book is read by the display request of the administrator and displayed on the display unit 45. G3 in FIG. 14 shows an example of the display result. The bullet number management book can be printed out by a printer (not shown) or recorded on an external recording medium such as a magnetic disk, an optical disk, or a memory card by a management book output operation in the key input unit 46.

(4) Maintenance inspection
The adapter device 3 is provided with inspection terminals 3b and 3b as shown in FIG. 15, for example. The user or manager connects both ends of the connection cable 8 to the inspection terminals 3b and 3b. Then, an application program for the continuity test is started in the control device 4. Then, in accordance with an instruction from the control device 4, the adapter device 3 applies a voltage for continuity test between the inspection terminals 3b and 3b, thereby conducting a continuity test of the connection cable 8. Then, the result of the continuity test is displayed on the display unit 45 of the control device 4. FIG. 16 shows an example of the display result.

  Further, when the operation check of the bullet counter 2 is performed, it is performed as follows. That is, the user or the manager installs the bullet number counter 2 in the slot 3 a of the adapter device 3. In this state, an application program for checking the bullet counter is started in the control device 4 and the program is executed. If it does so, the test signal regarding the inspection item set beforehand with respect to the bullet counter 2 will be supplied from the control apparatus 4, and the response signal will be received by the control apparatus 4. FIG. The control device 4 analyzes the received response signal and displays a list of the analysis results on the display unit 45. FIG. 17 shows an example of the display result.

  As described above, in the first embodiment, the bullet number counter 2 is attached to the main body portion of the firearm 1, and the bullet sensor 6 including the two optical sensors DS1 and DS2 arranged at regular intervals is barreled. It is attached to the extinguisher 1b at the tip. Based on the detection signals output from the two optical sensors when the actual bullets are fired, the bullet counter 2 detects the passage of bullets and the passage speed of the bullets. Judge the presence or absence of firing, and count the number of fired bullets. Then, the count value of the projectile ammunition is sent to the control device 4 through the adapter device 3 together with the ID of the ammunition counter 2 and the ammunition number carried, and the control device 4 manages the ammunition number based on the information sent above. A book is created.

  Therefore, every time an actual bullet is fired in the firearm 1, the number of shots can be reliably counted. For this reason, the number of empty cartridge cartridges and the number of unused bullets are counted manually, the user does not memorize the number of shot bullets, and special equipment is used to prevent loss of empty cartridge cartridges. Therefore, it is possible to easily and accurately count and manage the number of fired bullets for each user. Therefore, the reliability of the bullet number management and the training effect can be further enhanced.

  At that time, in addition to the presence / absence of bullet passage, the passage speed of the bullet is detected, and the presence / absence of the bullet is determined from the result. For this reason, it is possible to more accurately determine the firing of bullets by eliminating detection of other similar events such as muzzle maintenance operations.

  In the first embodiment, the bullet wave counter 2 detects an impact waveform at the time of launch by the impact sensor 21, identifies the shot of the bullet from the detected impact waveform, and counts the number of shots as the number of shot bullets. It counts at 25. Therefore, even in the case of empty-blade shooting training, the number of fired bullets can be counted reliably.

  In addition, at that time, the acceleration level of the impact is detected from the impact waveform detected by the impact sensor 21, and the presence or absence of firing is determined by comparing the detected value with the threshold value for impact determination. For this reason, the impact generated by the shooting can be more accurately detected by clearly distinguishing it from other causes, for example, the impact generated when the gun collides with something.

  Further, the operation mode of the actual bullet shooting training and the operation mode of the empty package shooting training are automatically switched by detecting whether or not the bullet sensor 6 is mounted in the bullet counter 2. For this reason, it is not necessary for the user to set the mode each time, so that the number of shots can always be counted in an appropriate operation mode.

  Further, in the first embodiment, the adapter device is provided with inspection terminals 3b and 3b, and both ends of the connection cable 8 are connected to the inspection terminals 3b and 3b, whereby the control device 4 conducts the continuity test of the connection cable 8. Like to do. In addition, with the bullet counter 2 mounted in the slot 3a of the adapter device 3, the control device 4 starts an application program for checking the bullet counter, thereby performing an operation test of the bullet counter 2. Yes. Therefore, the user or administrator can automatically confirm the conduction state of the connection cable 8 and the operation state of the bullet number counter 2.

(Second Embodiment)
In the second embodiment of the present invention, in a handgun that cannot be equipped with a ballistic sensor in terms of operation or structure, the presence or absence of firing or shooting is indirectly determined by using the sliding motion of the handgun slide during shooting. The number of shots or the number of shots is counted.

  FIG. 18 is a perspective view showing a configuration of a handgun provided with a bullet number measuring apparatus according to the second embodiment of the present invention, and FIGS. 19A and 19B are a front view and a side view, respectively. The handgun 10 according to this embodiment includes a main body portion 51 and a slide portion 52 attached to the main body portion 51 so as to be slidable in the front-rear direction. This slide portion 52 reciprocates when a bullet is fired.

  For example, a 5 mm square magnet 54 is attached to the side surface of the slide portion 52. As the attachment means, for example, fixing by an adhesive is used. On the other hand, a detector 53 is attached to the tip of the main body 51. The detector 53 is fixed by screws 53a in a state in which the main body 51 is sandwiched from both sides thereof. For example, as shown in FIG. 21, the detector 53 is provided with two magnetic sensors S1 and S2 arranged at a predetermined interval.

The magnetic sensor S1 is used to detect the slide operation speed of the slide portion 52. When the slide portion 52 performs a reciprocating operation in which the slide portion 52 slides from a fixed position to a retracted position and then returns to the fixed position, The magnet 54 attached to the slide part 52 is installed at a position where the magnetism can be detected.
The magnetic sensor S2 is used to detect the amount of sliding motion of the slide portion 52. When the slide portion 52 slides to a specified retreat position, the magnetism of the magnet 54 attached to the slide portion 52 is detected. Installed at a detectable position.

  The detector 53 is connected via a connection cable 55 to, for example, a bullet counter attached to a user (shooter) waist belt. At that time, the connection cable 55 is fixed to the grip portion of the handgun by the fixing tape 56 so as not to be loosened. The detection signals of the magnetic sensors S1 and S2 are transferred to the bullet number counter 2 via the connection cable 55. The bullet counter 2 has substantially the same circuit configuration as that shown in FIG. 6, and the detection signals of the magnetic sensors S1 and S2 are input to the A / D 31 in place of the detection signal of the bullet sensor 6.

  The bullet passage detection circuit 32 of the bullet counter 2 detects the slide operation speed and the slide movement range of the slide part 52 based on the detection signals of the magnetic sensors S1 and S2 input via the A / D 31, Based on the detection result, the presence or absence of firing is determined. Then, when it is determined that it has fired, a count pulse is generated, and this count pulse is supplied to the count circuit 33. The count circuit 33 counts the count pulses supplied from the bullet detection circuit 32 and outputs the count value to the control circuit 20 as the number of shots in the shooting training.

Next, the operation of the apparatus configured as described above will be described. The measurement condition setting process for the bullet counter 2 is performed from the control device 4 via the adapter device 3 as in the first embodiment.
When the user shoots with the handgun 10, the slide portion 52 is temporarily retracted from the state shown in FIG. 20A and then moved forward to return to the original position. At this time, the magnet 52 moves from the position C1 in FIG. 21 to the position C2 in FIG. 21, and then returns to the position C1. As the magnet 52 reciprocates, detection pulses as shown in FIG. 22 are output from the magnetic sensor S1 and the magnetic sensor S2 of the detector 53, respectively.

When the detection signals output from the magnetic sensors S1 and S2 are input via the A / D 31, the bullet detection circuit 32 of the bullet counter 2 performs a firing determination process as follows. FIG. 23 is a flowchart showing the processing procedure and processing contents.
That is, first, in step S231, the slide part 52 is retracted by shooting and the detection pulse of the magnetic sensor S1 is changed from "H" level to "L" level, and then the slide part 52 returns to the original position and is detected. Based on the time Δt until the pulse again changes from the “L” level to the “H” level and the slide operation amount L, the slide operation speed L / Δt of the slide unit 52 is calculated. Then, the calculated sliding motion speed L / Δt is compared with a threshold value to determine whether or not the sliding motion speed L / Δt is faster than the threshold value.

  As a result of the determination, if the slide operation speed L / Δt is faster than the threshold value, the process proceeds to step S233 to determine whether or not a detection pulse is output from the magnetic sensor S2. If a detection pulse is output from the magnetic sensor S2 as shown in FIG. 22, it is determined that the slide part 52 has slid to the specified retraction position C2, and the process proceeds to step S235, where a count pulse is generated. To do. The count circuit 33 counts the count pulses generated from the bullet detection circuit 32 and outputs the count value to the control circuit 20 as the number of shots in the shooting training.

On the other hand, in step S231, it is determined that the slide operation speed L / Δt has not reached the threshold value, or in step S233, it is determined that the slide portion 52 has not been slid to the specified reverse position. If it is detected, the trajectory detection circuit 32 determines that it is not a slide movement by shooting, and moves to step S232 and step S234, respectively, and does not generate a count pulse.
Note that the processing after the shooting training and the maintenance processing are performed in the same manner as in the first embodiment described above.

  As described above, in the second embodiment, the magnet 54 is attached to the side surface portion of the slide portion 52 of the handgun 10, and the detector 53 including the two magnetic sensors S1 and S2 is attached to the main body portion 51. The slide operation speed and the slide operation amount of the slide unit 52 at the time of shooting are detected by the magnet 54 and the magnetic sensors S1 and S2, and the presence or absence of firing is determined based on the detection result, and the number of fired bullets is counted. I am doing so.

  Therefore, even if the handgun 10 is not operational or structurally impossible to mount the bullet sensor, the number of bullets fired can be reliably counted each time a bullet is fired. For this reason, as in the first embodiment described above, the number of empty shells and the number of unused bullets are counted manually, and the number of fired bullets is not memorized by the user. It is possible to easily and accurately count and manage the number of shots of actual bullets for each user without providing any special equipment in the gun to prevent the loss of the cartridge case.

  In addition, by using the two magnetic sensors S1 and S2, the slide operation speed and the slide operation amount of the slide unit 52 are detected and the presence or absence of firing is determined based on the detection results. It is possible to more accurately determine the firing of bullets by eliminating other similar events such as the maintenance operation of the unit 52.

(Third embodiment)
The third embodiment of the present invention detects the sliding motion of the slide portion using a magnetic detection method based on electromagnetic induction in the handgun 10 that is not operationally or structurally mountable with a ballistic sensor, Based on the detection result, the presence or absence of bullets is judged and the number of bullets fired is counted.

24 and 25 are a side view and a front view, respectively, of a handgun provided with a bullet number measuring apparatus according to the third embodiment of the present invention. The configuration of the bullet number counter is basically the same as that shown in FIG. 6 and will not be described in detail.
A magnetic field detector 61 is attached to the main body portion 51 of the handgun 10 with a screw 63. The magnetic field detector 61 includes a pair of coil portions 62 and 62. These coil parts 62 and 62 are installed facing both side surfaces of the slide part 52 as shown in FIG. These coil portions 62 and 62 are connected via a connection cable 55 to, for example, a bullet counter (not shown) attached to a user's waist belt. The connection cable 55 is fastened to the grip portion of the handgun 10 by the cable fixing tape 56 so as not to be loosened.

  As shown in FIG. 26, the coil parts 62, 62 are formed by winding a conducting wire 62b around a core 62a, and detect a change in the magnetic field accompanying the movement of the slide part 52 as a change in the value of the current flowing through the conducting wire 62b. This change in current value is detected by a detection circuit provided in the bullet counter. The detection circuit obtains a change in impedance based on the change in the current value, and determines whether or not the slide operation of the slide unit 52 is due to shooting based on the change in impedance.

  For example, the amount of change in impedance is compared with a threshold value. When the amount of change in impedance exceeds the threshold value, it is determined that the slide operation of the slide unit 52 is due to the bullet firing. Also, the impedance change speed (the time from when the impedance change is started until the threshold value is reached) is detected. If the detected change speed is equal to or lower than the predetermined speed, it is determined that the slide operation is performed manually.

The detection circuit outputs a count pulse when it is determined that the sliding operation is due to the firing of a bullet. The count circuit counts the count pulse and outputs the count value as the number of fired bullets.
Note that the processing after the shooting training and the maintenance processing are performed in the same manner as in the first embodiment described above. In addition, the coil portions 62 and 62 of the magnetic field detector 61 are mounted in the vertical state as shown in FIG. 27 in addition to being attached to the main body portion 51 of the handgun 10 in the horizontal state as shown in FIG. You may make it attach to the main-body part 51 of the handgun 10. FIG.

  As described above, in the third embodiment, the slide operation of the slide unit 52 of the handgun is detected using a magnetic detection method based on electromagnetic induction, and whether or not a bullet is fired is determined based on the detection result. I am trying to count the number of ammunition. Therefore, as in the second embodiment, even if the handgun 10 is not operationally or structurally impossible to mount a bullet sensor, the number of shots is automatically counted each time a bullet is fired. The For this reason, it is not necessary to manually count the number of empty cartridges and unused bullets, and it is not necessary for the user to memorize the number of fired bullets, and special equipment is provided to prevent the loss of empty cartridges. There is no need to provide a gun, and the number of shots can always be easily and accurately counted and managed.

  In addition, the magnetic field detector 61 of this embodiment has fewer failures than the second embodiment because it is not necessary to attach the magnet 54 to the slide portion 52. In addition, unlike the case where an optical sensor is used, no power is consumed in the bullet sensor, so the battery life of the bullet counter 2 can be extended, and the detection accuracy due to dirt is less likely to occur, and there is no need for cleaning. Therefore, there is an advantage that maintenance becomes easy.

(Other embodiments)
In the first embodiment, the presence / absence of bullet passage and the bullet velocity are detected based on the detection signals of the optical sensors DS1 and DS2, and when the bullet passage is detected and the bullet velocity exceeds a threshold value, Although it is determined that the bullet has been fired, it may be determined that the bullet has been fired when either one of the conditions is satisfied. In addition, in the case of empty bombardment shooting, the acceleration level of the shock waveform is compared with the threshold values THa and THa ′ for shock determination, and the presence or absence of shooting is set based on the result. However, the present invention is not limited to this, and any one of the number of acceleration changes, the generation duration, and the frequency is detected from the impact waveform, and when the detection result satisfies a predetermined determination condition, the shooting is performed once. It may be determined that the count value is counted up.

  In the first embodiment, the bullet sensor 6 and the bullet counter 2 are connected via the connection cable 8, but may be connected using optical communication means or wireless communication means. Good. In addition, information is exchanged between the bullet number counter 2 and the control device 4 via the adapter device 3 and the connection cable 5. However, between the bullet number counter 2 and the control device 4, optical communication means, You may make it connect directly using a wireless communication means.

  Further, in the first embodiment, in the actual bullet shooting mode, the presence / absence of shooting is determined based on the detection signal of the penetration sensor 6, and in the empty package shooting mode, the presence / absence of shooting is determined based on the detection signal of the impact sensor 21. I tried to do it. However, the present invention is not limited to this, and in the actual bullet shooting mode, the presence or absence of actual bullets may be determined using both the detection signal of the bullet sensor 6 and the detection signal of the impact sensor 21 in combination.

  In the second embodiment, the detector 53 is attached to the main body portion 51 of the handgun 10 and the magnet 54 is attached to the slide portion 52. Conversely, the magnet 54 is attached to the main body portion 51 of the handgun 10. The detector 53 may be attached to the slide portion 52 while being attached. In addition, the attachment positions of the detector 53 and the magnet 54 may be set as long as the shooting operation is not hindered.

  Furthermore, in the first embodiment, the bullet counter 2 is detachably attached to the firearm 1, but it may be fixedly attached. In this case, the information input / output means can be realized by directly connecting the fire bullet number counter and the control device by a connection cable, optical communication means or wireless communication means as described above.

  In addition, the shape and configuration of the bullet sensor 6 and the bullet counter 2 and their functions, the mounting position of the bullet sensor 6 and the bullet counter 2 with respect to the firearm 1, its mounting means, and the process of determining whether or not the single counter is fired The procedure and processing contents, the configuration and function of the ammunition management system, the function of the control device, and the like can be implemented with various modifications without departing from the scope of the present invention.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
