Abstract
The invention provides an automatic target-scoring device based on a pressure sensor. The automatic target-scoring device consists of the pressure sensors (1), a signal processor (2), a back plate (3), a rubber pad (4) and a front plate (5). According to the automatic target-scoring device, the four pressure sensors (1) are mounted between the front plate (5) and the back plate (3) and are distributed squarely. When the front plate (5) is impacted by a bullet, the impact force of the bullet is transferred to the pressure sensors (1). The size of an electric signal output by each pressure sensor (1) is directly proportional to the magnitude of the impact force and is inversely proportional to the distance between a force bearing point and a point of impact. The signal processor (2) consists of a signal amplification circuit and an A/D conversion circuit; after being amplified by the signal amplification circuit, the electric signals output by the pressure sensors (1) are converted into digital signals through the A/D conversion circuit and then are transferred to a computer through a data transmission circuit according to a certain communication protocol. The invention provides a method for calculating the actual position of the point of impact in a standard target map by comparing the magnitudes of the impact forces exerted on all the pressure sensors.
Description
Art
The present invention relates to a kind of automatic scoring round target device of depended on pressure sensor identification point of impact.Particularly give the simple structure only having three or four micro pressure sensors.
Background technology
Divide according to operation principle, disclosed automatic target-indicating technical scheme has at present:
1. ultrasonic wave location target assembly.Be according to ultrasonic wave positioning principle, use ultrasonic probe to detect the device of point of impact position.The suppression of the method to environmental noise has strict requirement, has very high requirement to the antijamming capability of equipment.Be not suitable for quick burst-firing, and be difficult to overcome interfering with each other between adjacent target position.
2. based on the coordinate target assembly of image procossing.It is the technical scheme using camera to do IMAQ.The change of ambient light is very large on result of use impact.And, the differentiation of the many shell holes of overlap is still be unable to do without to the participation of people.Current precision is not high, the progress of just waiting in expectation image rectification technology and shell hole recognition technology.
3.PSD (Position Sensitive Detectors line scan image sensor) linear array coordinate target assembly.Be the PSD line scan image sensor of use two one dimensions, utilize the measurement of coordinates principle that crosses to realize the technical scheme of coordinate setting.Require that there is good, stable light source at scene, require higher installation and Adjustment Technology, and maintenance cost is high.
4. laser coordinate target assembly.Use Laser emission to receive pipe, detect the device of bullet through position by the method for many laser beam formation two-dimensional grating light curtains.To ambient light sensitive, be easily disturbed.Indication of shots precision depends on the density of grating.To improve precision, just needing more how high-precision, the expensive laser of equipment to pipe, manufacturing cost is increased.
In sum, current automatic target-indicating method, relies on the collection to voice signal or light signal, is therefore difficult to change (comprising illumination, noise, the temperature etc.) harmful effect to result of use eliminating the environment when gathering.Such as from adjacent target position sound interference or the shadow is rocked or lightning flashes and thunder rumbles, just signals collecting result may be destroyed and cannot give for change.Current automatic target-indicating method, does not always break away from the puzzlement of " how eliminating noise interference " difficult problem in acoustic-electric conversion or opto-electronic conversion.Particularly be difficult to be used in smoothly the training occasion under field extreme environment.
Summary of the invention
In order to improve antijamming capability and recognition capability, thoroughly eliminating wrong report and failing to report phenomenon, The present invention gives a kind of by environmental disturbances, based on the automatic scoring round target device of pressure sensor.It did not both use photosensitive detecting element, did not use the detecting element to sound sensitive yet, but have employed only to pressure-sensitive pressure sensor.
Structure of the present invention mainly by: 1. a few part such as pressure sensor, 2. signal processing circuit, 3. postnotum, 4. rubber blanket, 5. front panel forms.
Three (or four) pressure sensor (1) are arranged between front panel (5) and postnotum (3) by the present invention, (or square) triangular in shape distribution.Time front wall (5) is subject to projectile impact, the impact of bullet is passed to pressure sensor (1).And each pressure sensor (1) exports the size of the signal of telecommunication and is directly proportional to the size of suffered impact and is inversely proportional to its distance to point of impact.Signal processing circuit (2) is made up of signal amplification circuit, A/D converter circuit; After the signal of telecommunication that pressure sensor (1) exports is amplified by signal amplification circuit, data signal is transferred to again through AD D/A converting circuit, computer is passed to according to certain communication protocol again, for application such as record, calculating, display, statistics and preservations through data transmission circuit.Prepare a computer program according to " equilibrium equation of parallel force system (make a concerted effort in parallel force system be zero, resultant moment be zero) " in rational mechanics, can calculate accurately, quickly and demonstrate the physical location of point of impact in standard target figure.
Be exactly briefly that the present invention, by the size of impact comparing three or four pressure sensors and be subject to, determines the position of point of impact.
Critical piece illustrates:
The function of pressure sensor (1) is that pressure change is converted to the signal of telecommunication.Can adopt coin shape micro pressure sensor, its back side is fixed on postnotum (3), the force-detecting position in front and front panel (5) close contact; Its power line is connected with signal processing circuit (2) with output line.Pressure sensor described here, makes a general reference the force snesor to power sensitivity, various different operating principle, such as resistance-type, capacitance pressure transducer, and LOAD CELLS, displacement transducer, acceleration transducer, torque sensor etc.
The function of signal processing circuit (2), after being amplified by the signal of telecommunication, is carried out A/D analog-to-digital conversion, then send computer to by wireless or wire transmission mode.
The function of postnotum (3) is the function on chassis, and all parts are all arranged on above it.
The function of rubber blanket (4) is to provide buffering, to reduce the impulsive force to pressure sensor; There is the effect of water proof and dust proof simultaneously.
The function of front panel (5) is that bullet impact power is passed to each pressure sensor, can adopt steel plate or other shock proof rigid material.Can there be one deck rubber facial mask on its surface, while providing round target pattern, provide buffering, slackens the bounce-back kinetic energy of bullet.
Compared with prior art, the invention has the beneficial effects as follows:
1. because pressure sensor is only to presser sensor, and to environmental noise and illumination variation insensitive, therefore there is extremely strong antijamming capability, except be applicable to Analysis of Indoor Firing match occasion except, also can be used for various severe field exercise environment.
2. being widely used of pressure sensor, technology maturation and precision are high, not only easily can realize the fast automatic identification of point of impact, and the erroneous judgement being expected to thoroughly eliminate common overlapping point of impact is failed to judge.This, for the training occasion of quick burst-firing, has particular importance meaning.
