2. Description of the Related Art As an example of a conventional device, as shown in FIG. 23, there is a device that determines information about the trajectory of an ultrasonic projectile passing through a predetermined region (see Japanese Patent Publication No. 62-17193).

This device detects an air-carrying shock wave 71 generated from a supersonic flying object (launched bullet) 70 passing through a predetermined area at supersonic speed by at least three converters 72 arranged in a straight line. , An output is generated in response to the air-carrying shock wave 71, the time delay between the respective output signals is measured, the information regarding the trajectory of the flying body, that is, the bullet passing position is measured from the time delay, and the bullet is fired. It is a device that displays the shooting result on the display 73 at the hand of each shooter.

The shooting result is displayed on the display unit near the shooter in real time. However, since the shooting result (the number of shots) displayed on one screen is limited, when the shooting is performed many times, it is displayed on the display unit. It is necessary to erase the displayed shooting result (or save it in a storage means built in the display) to display a new screen, and each shooter operates the operation button provided on the display 73 to display the screen. It was supposed to switch.

[0005]

In the conventional device shown in FIG. 23, the display 73 at the hand of each shooter stores the data displayed by each shooter's own operation in the memory and switches the display screen. When an archer who is not familiar with how to use the device needs to perform the operation, there is a disadvantage that an erroneous operation may occur and he cannot concentrate on the shooting.

[0006] Further, it is necessary for the shooting section and the shooting section management who guide the shooting to check the shooting status of each shooter by moving to each shooter's hand. There is a drawback in that the teaching cannot be performed efficiently.

Further, the conventional device is a device used in a single lane, and when used in a plurality of lanes,
It is assumed that the lanes will be used at a distance such that the airborne shock waves of bullets in adjacent lanes will not reach them. However, in the case of a narrow shooting range, it is not possible to secure a sufficient distance between lanes, so the air-borne shock wave from the bullets in the adjacent lane may be erroneously detected, or the bullet of the shooter shooting in the adjacent lane may be mistaken for the lane. Even if you pass near the target, you will mistakenly judge that it is the result of your own shooting.

Therefore, it is not a device that can be installed in a narrow shooting range and many shooters can simultaneously carry out shooting training.

An object of the present invention is to provide a device in which the shooter can concentrate only on shooting, the shooter can immediately recognize the result of his own shooting, and the shooting staff can carry out appropriate shooting instruction. That is.

The indicator rod 60 is arranged so that the target 1 approaches the proximity sensor 16a when the target 1 appears, and the target 1 approaches the proximity sensor 16b when the target 1 disappears. As a result, a detection signal is output from each sensor 16 when the target 1 appears or is hidden. The counter 17 holds the value at that time by the detection signal from each sensor 16. This value is the target appearance timing and the obliteration timing, and it is possible to determine whether or not the bullet has reached the target when the target appears, based on these timings and the bullet detection timing of the counter 58 notified from the bullet position measuring device 2. .

The shooter display unit 4 calculates the impact position, scores and displays it according to the flowchart shown in FIG.

First, as soon as the notification of shooting start from the shooter sensor 5 is received, the value of the counter 24 is stored as shooting timing information, and the "out-of-target" judgment timer is started to wait for bullet information from the target drive device 3. .

Immediately after the bullet information from the target drive unit 3 is obtained, the shock wave detection time is calculated from the detection timing information included in the bullet information, and the bullet information obtained by comparing the shooting timing information and the shock wave detection time is obtained. Determine if it is your bullet information. Details of the determination method will be described later.

When it is determined that the bullet is one's own bullet, that is, when the bullet is not “out-of-target” or “ricochet”, the impact position calculation and scoring described later are performed, and the calculation result is displayed on the liquid crystal display unit 28. Display in 17 format.

When it is determined that the bullet is not the bullet of its own, that is, when the bullet is “out of focus” or “bounce”, the next bullet information from the target drive device 3 is awaited. If the "off-target" determination timer times out while waiting for the next bullet information, it is determined that the bullet has landed at a location where the bullet position measurement unit 2 cannot measure it, that is, it is off-target. Then
The liquid crystal display unit 28 displays "outside target" and waits for the next shooting start notification from the shooter sensor 5.

The scoring is performed by determining the scoring range according to the training conditions such as the shooting distance, the shooting posture, and the type of gun used, which are notified at the same time when the shooting training start command is issued from the shooting staff member display unit 8.

During the shooting training, the shooting clerk and the shooting clerk indicate the shooting training status to any display unit 4 for the shooter by the operation button 44 of the shooting clerk display unit 8 and the operation button 40 of the shooting clerk display unit 6. You can request. The display unit 4 for the shooter, which has been requested for the shooting training status, notifies the present and past shooting training status via the communication line 10. The shooting section executive display unit 8 and the shooting section display unit 6 display the shooting training status from the shooter display unit 4 in the format of FIG. As a result, it becomes possible to efficiently instruct the shooting of the shooter for each shooting.

When the shooting training is completed, the shooting staff member notifies the shooting unit display unit 4 of the end of the shooting training through the communication line 10 by the operation button 44 of the shooting staff member display unit 8.

Immediately after receiving the end of the shooting training, the shooter display unit 4 finishes one shooting training, and notifies the shooting data processor 9 of the shooting training result together with the identification number via the communication line 10.

Upon receipt of the shooting training result, the shooting data processor 9 immediately stores the shooting training result in the auxiliary storage unit 47 and outputs the shooting training result received from the printer 51 in the format shown in FIG. The storage in the auxiliary storage unit 47 is managed by the identification number and the date so that it can be referred to.

As a result, the shooter can confirm the shooting result during the shooting training and the shooting result after the shooting training without operating his / her own display unit 4 and can concentrate on the shooting training. it can.

Next, a method of determining whether or not the bullet information is obtained by the bullet fired by the shooting detected by the shooter sensor 5 in this embodiment will be described. First, the consistency of bullet information sent from the target drive device 3 is confirmed. It is determined whether the bullet information transmitted is information immediately after shooting. Next, it is determined whether or not this bullet information is generated by a shock wave generated from one bullet.

The processing of 1 to 3 shots will be described below. The only reliable information known at the time of shooting is the shooting distance. The information about the bullet that has landed is given by the bullet speed, the bullet flight time, and the bullet position coordinates. Therefore, first, the distance calculated from the bullet speed and the bullet flight time (bullet flight distance) is compared with the actual shooting distance.

The initial velocity of the bullet at the muzzle is unknown, and the bullet decelerates slightly until it exits the muzzle and hits the target 1. The amount of deceleration changes depending on the surrounding weather conditions. Therefore, if the bullet flight time is correct, the calculated bullet flight distance will be slightly larger than the actual shooting distance.

However, since the flight time of the bullet is calculated from the time difference when the bullets are detected by the two devices (the bullet position measuring device 2 and the shooter sensor 5), the error due to the software processing load of each device and the time adjustment of each counter described later are performed. It contains an error. Therefore, if the bullet flight distance is in the range of half to twice the actual shooting distance, it is determined to be in the own shot range.

Next, from the position within the self-shot range, the impact position X
Exclude those with large coordinates. The installation distance from the adjacent target is about 3 (m), and the bullet that hit the adjacent target should be the bullet shot by the adjacent shooter, so the horizontal distance is 1.5 (m) from the center of the target. ) The bullets that are missed above are not self-shot.

The processing after four shots will be described below. Reliable information known at the time of shooting is the shooting distance, the speed of a bullet judged to be a self-shot and the flight distance of the bullet. The information of the bullet that has landed is given as the bullet speed, bullet flight time, and bullet position coordinates. Therefore, the bullet flight distance calculated from the bullet speed and the bullet flight time is compared with the average flight distance of the bullets judged to be own bullets in the past.

The bullet flight distance of the bullet fired from the same small weapon should be almost the same as the average flight distance of the bullets judged to be past bullets. Therefore, if the bullet flight distance is within 4σ of the average flight distance of the bullets judged to have been past bullets, it is determined to be within the bullet range.

Further, in order to determine whether or not the one within the own-shot range is a ricochet, the velocity of the bullet is compared with the velocity of the bullet determined to be the previous bullet. The average velocity of bullets that were judged to be self-shots in the past should be approximately the same as long as there is no sudden change in weather conditions during the shooting period. Therefore, if the bullet velocity is within 4σ of the average bullet velocity of the bullets judged to be the past bullet, it is determined to be within the bullet range.

Next, those having a large X-coordinate of the landing position are excluded from those within the range of the own bullet. The installation distance from the adjacent target is about 3 (m), and the bullet that hit the adjacent target should be the bullet shot by the adjacent shooter. Therefore, the horizontal distance is 1.5 (m) from the own coordinate center. ) The bullets that are missed above are not self-shot.

FIG. 1 shows a processing procedure according to the above determination method.
9, FIG. 20 and FIG. The processing contents are described below. ◆ The counter 24 sets the shooting timing to Tf,
Let Th be the detection timing obtained by the counter 58, Dfp be the shooting distance, and Vb be the residual velocity of the bullet. First, the bullet flight time Tof is calculated from the difference between the shooting timing Tf and the detection timing Th (step 91). Counter 17 here
The (target drive device 3), the counter 24 (display unit 4 for shooter), and the counter 58 (launching position measuring device 2) are 16-bit, 1200 Hz hardware counters.

When the relationship between Vb and Tof is too far apart (when there is a change more than the change in bullet velocity due to wind or air), it is set as "next bullet" or "other bullet" and No further processing is performed. The criteria for judgment are described below. ◆ If Tf ≧ Th, Tof = Tf−Th [S] (3) ◆ If Tf <Th, Tof = Tf−Th + 54.6133 (4) ◆ If Tof <0 or Tof> 12 [s], It is set as “other bullet” (procedure 92). ◆ 0 <Tof <12 and Tof ≧ (Dfp ×
In the case of 5) / Vb, it is regarded as the "next bullet" (procedure 99).

Next, the range of the bullet velocity that can be detected as the own bullet (the allowable difference Vdmin from the average bullet velocity Vbm of the bullet) is calculated. However, the calculation method is changed depending on whether the flight time variation is large or small.

The velocity of the bullet is decelerated by the air resistance while the bullet shot at the firing point flies in the air, so that the velocity of the bullet measured by the impact position measuring unit 2 is higher than that at the muzzle. It will be slower. Therefore, the velocity of the bullet measured by the bullet position measuring unit 2, that is, the residual velocity Vb of the bullet, should be faster than 0 m / s and slower than the velocity of the muzzle at the muzzle (1000 m / s). When Vb <0 or Vb> 1000 m / s, it is determined to be "outside" (procedure 95).

The variation in flight time σ is obtained from the variation in bullet velocity Vvar because the shooting distance is constant. ◆ When σ = Vvar / Dfp> 10 ◆ Vdmin = 0.05 × (0.1 × Vbm × Vbm / Dfp)… (5) ◆ VTofdmin = 0.05 × (0.1 × VTofm × Vbm / Dfp) ◆ …… (6) ◆ However , VTofm = average value of flight distance calculated from velocity and flight time ◆ VTofdmin = Tolerance of flight distance ◆ σ = Vvar / Dfp ≤ 10 ◆ Vdmin = 0.05 x Vbm (7) ◆ VTofdmin = 0.05 x VTofm (8) Up to the first three shots, if the bullet velocity is within the following range, the temporary shot position coordinate P is calculated using the above formula as the bullet shot.
Calculate (Xp, Yp). ◆ Here, if the calculated X position of the impact position is ± 1.5 (m) or more, it is regarded as “another bullet”.
◆ 0.5 × (Dfp / Tof) <Vb <2 × (Dfp / Tof)… (9) ◆ VTofd = 0 …… (10) ◆ VTofd = Flight distance and average value (VTofm) calculated from remaining speed and flight time VTofd is set to 0 when the condition of Expression (9) is satisfied.

The processing after the fourth shot is as follows. ◆ First,
The velocity difference Vd between the actually detected velocity and the average velocity is calculated. ◆ Vd = Vb-Vbm (11) ◆ If Vd is outside the permissible range obtained above, "Ricochet"
To be a candidate. In addition, the flight distance is calculated from the bullet velocity and the flight time, and if it is within the allowable range, it is determined that it is within the impact detection time. ◆ If neither Vd2 <16 × Vvar or | Vd | ≦ Vdmin is set, the flag of “jump” is set. ◆ If the flag of “Ricochet” is set, VTofd = Vbm × Tof−V
Tom. ◆ If you don't set the flag of "Ricochet", V
Tofd = Vb × Tof−VTofm. ◆ Above VTofd
If the following conditions are satisfied, the flag of “impact landing” is set.
◆ VTofd2 <16 × VTofvar or | VTofd | ² ≤VT
ofdmin As a result, the calculation formulas (1) and (2) described above are used as the self-shot bullet (procedure 128) only when the “shot bullet” flag is set and the “jump” flag is not set (procedure 115). To calculate the temporary landing position coordinates P (Xp, Yp) (step 12)
9). If the provisional bullet landing position X-coordinate calculated here is ± 1.5 (m) or more (procedure 130), it is determined to be "another bullet" (procedure 13).
1). ◆ Again, the VTofd flag is not set,
When> 0 (procedures 125 and 126), the subsequent processing is not performed for the present firing, assuming that the deviation is later than the self-shot area. ◆ Here, the number of shots fired is Be. However, Be
Is the value counted only when the "shot impact" flag is set and the "shot bullet" flag is not set.

Vbm, VTofm, Vvar, VT used in the above
ofvar is calculated as follows. ◆ When Be <10, NS = Be, ◆ When Be ≧ 10, NS = 10 ◆. ◆ Average velocity (Vbm): ◆ Vbm = Vbm- (Vbm / NS) + (Vb / NS) (12) ◆ Square of average velocity (Vbsq): ◆ Vbsq = Vbsq- (Vbsq / NS) + (Vb ² / NS) ◆ (13) ◆ Average of flight distance (VTofm) obtained from velocity and flight time: ◆ VTpfm = VTpfm− (VTofm / NS) + {(Vb × Tof) / NS} ◆ …… (14) ◆ Squared flight distance (VTofsq) obtained from velocity and flight time: ◆ VTofsq = VTofsq- (VTofsq / NS) + {(Vb × Tof) ² / NS} ◆ …… (15) ◆ In case of Be ≧ 2, ◆ Variation of velocity (Vvar): ◆ Vvar = (Vbsq-Vbm ² ) × {NS / (NS-1)} ◆ …… (16) ◆ Variation of flight time (VTofvar): ◆ VTofvar = (VTofsq-VTofm ² ) × {NS / (NS-1)} ◆ (17) ◆ Next, the method of calculating the landing position of this embodiment will be described.

The display unit 4 for the shooter uses the above-mentioned calculation formulas (1) and (2) to calculate the temporary landing position coordinates P (Xp, Y).
p) is calculated, and the correction value of the shooting angle generated from the relationship between the shooting position and the target position is calculated. The calculation procedure is described below. ◆ First, recognize the positional relationship between the shooter, the center of the target, and the shock wave sensor. Draw a perpendicular from the center of the target, draw a perpendicular on the horizontal plane including the acoustic sensors 11a, 11c, and 11d of the landing position measuring device 2, and enter the coordinates of each sensor in the coordinate system with the origin at the intersection with this horizontal plane. I'll do it. The coordinate relationship is shown in FIG. The items stored in advance are shown below. ◆ 100 m, 200 m, 300 m shooting seat coordinates (coordinates of the acoustic sensor 11 of the shooter sensor 5): (In this embodiment, there are a shooting range of 100 m, a shooting range of 200 m, and a shooting range of 300 m in the shooting range. The shooting coordinates include the shooting coordinates of 100 m, the shooting coordinates of 200 m, and the shooting coordinates of 300 m. Which remote to use is set by the remote control terminal 7. This information is set. Display unit 8 for shooting officers
Is transferred to each archer display unit 4 via. ) -Coordinates of each acoustic sensor 11 of the landing position measuring device 2 Next, the temporary landing position coordinates (Xp, Yp, 0) and the shooting position coordinates (Xs).
From h, Ysh, Zsh), the incident angle of the bullet is calculated, and the direction cosine of the shooting line is calculated.

Θx = −tan ⁻¹ {(Xp−Xsh) / Zsh} (18) ◆ LT = cos θy × sin θx, (20) ◆ MT = −sin θy, (21) ◆ NT = cos θy × cos θx (22) ◆ The direction cosine between the temporary bullet landing point p and each sensor is obtained.

SfPf = | Sfp × sin θf | (31) ◆ ScPc = | Scp × sin θc ｜ (32) ◆ SlPl = | Slp × sin θl ｜ (33) ◆ SrPr = | Srp × sinθr | (34) The distance from the temporary bullet landing point to each intersection is expressed by the following equation. ◆ PPf = | Sfp × cos θf | …… (35) ◆ PPc = | Scp × cos θc ｜ …… (36) ◆ PPl = | Slp × cos θl ｜ …… (37) ◆ PPr = | Srp × cos θr | …… ( 38) Therefore, the distance from Pf to Pc, Pl, and Pr is shown by the following equation.

PfPc = | PPf-PPc | (39) ◆ PfPl = | PPf-PPl | (40) ◆ PfPr = | PPf-PPr | (41) When passing through Pf on the line of fire As a reference, the time until the shock wave reaches each acoustic sensor 11 (TMf, TMc, TM

The counter 17 of the target drive device 3, the counter 24 of the display unit 4 for the shooter, and the counter 58 of the landing position measuring device 2 are 16-bit, 1200 Hz hardware counters, each operated by an independent clock signal from a crystal oscillator. is doing. Since the crystal oscillator has an error of several hundred ppm, the counters are not synchronized at all. In addition, since the power-on timing also differs depending on the device, it is necessary for the counter of each device to periodically adjust the time.

The shooting data processor 9 incorporates the same counter 61 as other devices, and periodically notifies all connected devices simultaneously via the communication line 10 using the value of the counter 61 as a reference time.

Shooter display unit 4 and target drive 3
As soon as the value of the counter 61 is received, the value of each of the counter 24 and the counter 17 is read out, and the reference time difference is calculated and stored from the difference. When a certain event occurs and the respective counters are read by the shooter display unit 4 and the target drive device 3, the reference time difference is always added so that the counters of the shooter display unit 4 and the target drive device 3 are substantially synchronized. It can be obtained as the value operated.

The counter 58 of the landing position measuring device 2 periodically reads the value of the counter 17 from the target driving device 3,
By storing the difference from the value of the counter 17 as the correction value, the timing when the air carrier shock wave is detected can be corrected by this correction value.

Next, a method of calculating the reference time difference will be described. ◆
When each device receives the reference time (the value of the counter 61) on the communication line 10 that the shooting data processor 9 periodically sends out, the display unit 4 for the shooter reads the counter 24,
The target driving device 3 reads the counter 17. Next, the difference between the reference time and the own counter value is stored. ◆ Of the stored time differences, the latest seven moving averages are calculated and that value is used as the reference time difference. When it is desired to know the time on the shooter display unit 4 (for example, the shooting detection time), the time adjusted to the reference time on the communication line 10 is known by adding this reference time difference to the value of the counter 24 of the shooter display unit 4. You can

Since each counter is a 16-bit, 1200 Hz hardware counter, the reference time difference is calculated as follows. First, the total of the time differences up to the past seven times, the maximum value of the time differences, and the minimum value of the time differences are calculated. Next, the difference between the minimum value and the maximum value is calculated, and it is checked whether the value exceeds half of the 16-bit counter (0x8000). If it exceeds, it is judged that there is a large variation in the time difference data, and the difference between the minimum value and the maximum value is more than half of the counter and the number of data less than half is compared, and only the data with the larger value is compared. Calculate the average value. If the time difference data is not exceeded, it is determined that the time difference data has no variation, and the average value is calculated from all the data.

Calculation method of time difference (ΔT (n)) ◆ Reference time on LAN line: Ts (n) ◆ Internal clock value when reference time is received: Ti (n) ◆ Ts (n) ≧ Ti (n) Case ◆ ΔT (n) = Ts (n) -Ti (n) ... (60) ◆ When Ts (n) <Ti (n) ◆ ΔT (n) = Ts (n) + 65536-Ti (n) ... ( 61) The average value is calculated by removing the maximum value and the minimum value in the target data group from the target data group. ◆ Calculation method of average value (ATs (n)) ◆ Maximum value of time difference: ΔTmax ◆ Minimum value of time difference: ΔTmin ◆ Number of data: N ◆ Number of data smaller than the value obtained by adding 32768 to the minimum value: M ◆ Selection Data: ΔTd ◆ Maximum value of time difference in selected data group: ΔTdmax ◆ Minimum value of time difference in selected data group: ΔTdmin ◆ ΔTmax-ΔTmin <32768 ◆ ATs (n) = {ΣΔT (n) -ΔTmax −ΔTmin} / (N−2) (62) ◆ ΔTmax−ΔTmin ≧ 32768 and NM ≧ M ◆ ATs (n) = (ΣΔTd−ΔTdmax−ΔTdmin) / (NM−2) ... (63) ◆ ΔTmax−ΔTmin ≧ 32768 and NM <M ◆ ATs (n) = (ΣΔTd−ΔTdmax−ΔTdmin) / (M−2) (64) Calculated reference time difference ATs (n) Reference time difference Δ one time ago
If the difference from Ts (n-1) is deviated by 30 counts (the counter frequency is 1200 Hz, the time is 25 ms) or more, the value deviated by 30 counts in the direction deviated from the reference time difference one time before is set. This is the reference time difference. ◆ Calculation method of reference time difference (ΔTs (n)) ◆ In the case of ΔTs (n-1) -ATs (n) <30 ◆ ΔTs (n) = ATs (n) (65) ◆ ΔTs (n-1)- When ATs (n) ≧ 30 ◆ ΔTs (n) = ΔTs (n-1) ± 30 (66)

As described above, according to the present invention, it is possible to shield the air carrying shock wave from the bullets of the adjacent lanes with the shielding plate and to extract only the bullets shot by oneself. Even in a narrow shooting range where a sufficient distance between lanes cannot be secured, it is no longer possible to misdisplay the shot of the shooter of the other lane shot by the target of one lane as the shot of the shooter of the target lane. It is possible for all shooters to perform shooting training at the same time.

Also, since the shooting training status is instantly displayed at the shooter's hand only by operating the button of the shooting staff, it is possible for the shooter to confirm the shooting result at hand without losing the shooting posture during the shooting training. Then, the shooter can concentrate on shooting.

Further, since the shooting staff and the shooting staff can easily confirm the training situation of the shooter, it is possible to immediately give appropriate shooting guidance.

Further, since the shooting result is automatically output, it is not necessary to display the bullet landing and the transcription of the bullet land in the supervisory section, and it is possible to efficiently carry out the training of more shooters. Become.
