Abstract
The present invention provides a ball firing training system which comprises a gun, a goal target made of self-recovery material, a sound measurement device and a computer automatic target-indicating system. The goal target of the system has the advantages of long service life, exact measurement, and no interference from surrounding natural light and noise.
Description
The present invention relates to a kind of ball firing training system.
The target of ball firing training system generally adopts paper target or wooden target at present, and the life-span is shorter.When carrying out gunnery training, need judge target site.Traditional visual method is slow owing to speed, poor accuracy, dangerous reason such as big, is replaced by other method gradually.Advanced at present ball firing training system is the light-seeking method, and it adopts some optical sensor and LASER Light Sources of arranging in length and breadth, and laser beam covers whole tested zone substantially.When emission when the bullet hit home, the horizontal and vertical light beam of instantaneous trip is judged target site thus.But this method has the following disadvantages, the one, take measures to avoid the influence of natural daylight to it, and this is difficult to realize under many circumstances; The 2nd, when the less or tested zone of bullet was big, its cost was very big, therefore is difficult to popularize.
The objective of the invention is: a kind of ball firing training system that localization method is not influenced by natural daylight and the target life-span is long that hits is provided.
Above-mentioned purpose is achieved by the following technical solution: a kind of ball firing training system, comprise rifle, target, measurement mechanism, also comprise Computerized automatic target-indicating system, described measurement mechanism is the sound measurement device, and described target is made by automatic resilient material.
Above-mentioned sound measurement device can be following structure: it comprises and is arranged at four pairs of sonic transducers that become rectangular arranged around the sector of fire, signal amplifies, filter circuit, analog-to-digital conversion, data acquisition circuit, the output signal of these four pairs of sonic transducers is by signal amplification, filter circuit, and analog-to-digital conversion, data acquisition circuit import Computerized automatic target-indicating system into.
Owing to adopted automatic resilient material as target, then this target is subjected to can restoring to the original state automatically after the gunslinging puncture, thereby can obtain the service life of length.Because what the present invention adopted is sonic transducer, therefore can not be subjected to the influence of natural daylight on every side, and can be because of tested zone the big or less sensor that increases of bullet.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the sound measurement schematic diagram among the present invention;
Fig. 2 is the circuit connecting relation block diagram among the present invention;
Fig. 3 is a computer program flow chart of the present invention.
In the present embodiment, target is made by automatic resilient material, and this kind material has obtained open on Internet, is prior art.
Fig. 1 shows the sound measurement principle, around the sector of fire four pairs of sonic transducers is set, and these four pairs of sonic transducers become rectangular arranged, and then the coordinate of the point of impact can be drawn by following method:
Wherein a pair of sonic transducer is decided to be first sensor 1, to be decided to be second sensor 2 with the sonic transducer of first sensor 1 on same minor face, be decided to be the 3rd sensor 3 with sonic transducer with first sensor 1 diagonal angle, to be decided to be four-sensor 4 with the sonic transducer of first sensor 1 on same long limit, the coordinate of the point of impact is obtained by following formula:
x＝(Vel
*Vel
*t4
*(t2
*t2＋t3
*t4－t2
*t4－t3
*t3)＋LENGTH
*LENGTH
*(t2＋t4－t3))/(2
*LENGTH
*(t2＋t4－t3))
Y=(Vel
*Vel
*T2
*(t4
*T4+t3
*T2-t2
*T4-t3
*T3)+WIDTH
*WIDTH
*(t2+t4-t3))/(2
*WIDTH
*(t2+t4-t3)) wherein: it is initial point with first sensor 1 that x, y are respectively the point of impact, is axis of abscissas to grow the limit, is horizontal stroke, the ordinate of axis of ordinates with the minor face; Vel=340m/s is the aerial spread speed of sound; T2, t3, t4 are respectively second sensor 2, the 3rd sensor 3, four-sensor 4 and receive the time of voice signal and the time difference that first sensor 1 is received voice signal t1; LENGTH is the distance on long limit; WIDTH is the distance of minor face.
Sonic transducer among the present invention is a ultrasonic sensor, and it can get rid of the interference of man-made noise effectively.
Fig. 2 shows the circuit connecting relation among the present invention.The present invention includes sonic transducer 10, signal amplifies, filter circuit 5, analog-to-digital conversion, data acquisition circuit 6, the output signal of these four pairs of sonic transducers is by signal amplification, filter circuit 5, and analog-to-digital conversion, data acquisition circuit 6 import Computerized automatic target-indicating system into; Wherein, Computerized automatic target-indicating system comprises that a computer 7, data processing software system 9 and one are by this computer-controlled display 8.Wherein, the content of computer data process software system is carried out flow process as shown in Figure 3: advanced line data collection, carry out digital filtering again, judge then whether the number of accepting and believing is actual signal, if not, then repeats above-mentioned data acquisition step, if, then obtain t2, t3, t4, judge again whether t2, t3, t4 satisfy the related constraint condition, if not with relevant treatment, then return data acquisition step, if, then t2, t3, t4 substitution formula are obtained the point of impact coordinate (x, y).
Whether above-mentioned the number of accepting and believing is that actual signal is judged for further filtering noise design, can design according to actual conditions, generally should adopt artificial intelligence technology, and this technology also is a prior art.
Because the present invention has adopted whether ultrasonic sensor, filter circuit and institute's number of accepting and believing are that actual signal is judged, therefore can get rid of various interference of noise, thereby more exactly the point of impact be positioned more satisfactoryly.
Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also carry out some kinds to the present invention and improve or modification, these improvement or modification all should be considered as belonging to protection scope of the present invention.
