Abstract
The present invention relates to a hitting point temperature difference localization method, and is applicable to accurate localization of hitting point in the shooting training. Said invention uses elastic material which can be rubber, foamed plastics and cowhide, etc. as bullet-receiving body, and adopts 8-12 micrometer long-wave infrared detector to monitor whole bullet-receiving body, at the moment when the bullet-receiving body is hit by bullet the place where the temperature difference is produced on the bullet-receiving body can be detected, and said temperature difference signal can be inputted into the computer to make processing, and the coordinate position of said hitting point on the bullet-receiving body can be accurately displayed.
Description
Technical field
Point of impact temperature difference localization method relates to placement technology is carried out in the bullet point of impact, is applicable in the gunnery training score calculation and and location determination are carried out in point of impact.
Background technology
Existing point of impact location technology mainly contains acoustic fix ranging method and double-deck rubbing paper screen method: the acoustic fix ranging method is made up of cavity, sensor; When bullet passes through cavity, form one in inside cavity and rise in the pressure wave of point of impact, arrive the time order and function of cavity periphery sensor according to pressure wave, just can calculate wave source---the position of point of impact just, the precision of this method depends on cavity acoustic characteristic, sensor characteristics difference, but after the point of impact on the cavity constantly increases, the acoustic characteristic of cavity is changed rapidly, the difference of sensor also is difficult to thoroughly eliminate, so to the point of impact locating accuracy, cavity can constantly increase and constantly reduce with point of impact.
Double-deck rubbing paper screen method adopts paper screen, infrared lamp and the thermal camera of two-layer reverse rubbing.Penetrate the paper screen of the two-layer reverse rubbing that fits tightly when bullet after, the infrared light that is positioned at 850～930 nanometer infrared lamps generation at screen rear portion sees through point of impact, being positioned at the anterior thermal camera of paper screen catches, because paper screen other parts can not see through infrared light, thermal camera can capture the paper screen rapidly and go up a bright spot that sees through shell hole, and determines the point of impact position by calculating thus, along with the rightabout rubbing of two layers of paper, shell hole on the rapid masking paper screen of meeting, making on the paper screen does not have printing opacity.The precision of this method depends on by cam lens spherical deformation, location algorithm, so positioning accuracy is higher, still because paper is influenced by air humidity easily, make the paper-rubbing mechanism fluctuation of service, and paper screen price is more expensive, and service life is short, and installation is inconvenient, maintenance cost is higher.
Summary of the invention
The deficiency of independent positioning method at above-mentioned bullet, the invention provides a kind of utilization impact position and have temperature characteristic with its periphery and position, and the location is accurate, the operation and maintenance point of impact temperature difference easily localization method.
The inventive method adopts anti-bullet to be subjected to body, and as rubber, foamed plastics, ox-hide etc., 8～12 microns Long Wave Infrared Probes and computer are realized.8～12 microns Long Wave Infrared Probes monitor the whole bodies that are subjected to, and are connected with computer and set up the coordinate corresponding relation by software for calculation, and the point of impact infrared information that the computer basis detects calculates the coordinate position of point of impact.Because object all can be launched long-wave infrared at absolute 0 ℃ more than the degree, temperature is high more, the long-wave infrared of being launched is strong more, so group launch into or puncture when being subjected to body, bullet and be subjected between body to produce strong friction, the temperature of impact place can raise rapidly, can produce the temperature difference with the temperature around it, the long-wave infrared of point of impact place emission also can be apparently higher than the emission level of peripheral normal temperature, be subjected on the Long Wave Infrared Probe of body in supervision all the time, can detect the infrared strong signaling point of point of impact, this signal machine software processing back as calculated just can calculate the accurate coordinate position that is subjected to point of impact on the body.
The invention has the advantages that: the location that utilizes the temperature difference of point of impact and its surrounding environment to carry out point of impact, the location of point of impact is become simply, accurately, reliable.Be subjected to body can adopt various objects of anti-bullet the or the material of anti-the bullet to make, damaged by the bullet that generally is subjected to of body, short of hole greater than caliber, just the coordinate that does not influence point of impact is accurately located, making to make greatly reduced by the requirement of body, not only price is marked down, also provides convenience for safeguarding, changing.Because utilizing temperature difference method is that point of impact itself is positioned, existing relatively method, the cost of locating accurate more, as to be subjected to body longer service life, gunnery training is lower.
The specific embodiment
The present invention adopts rubber to make and is subjected to body, before being subjected to body, fixedly mount the Long Wave Infrared Probe of 8～12 micron wave lengths, detector can monitor the whole body that is subjected to, and supervisory signal is passed through conversion give computer, computer is proofreaied and correct in advance by software, determines Long Wave Infrared Probe and the position corresponding relation that is subjected to body.After in being subjected to the attack of body quilt, bullet is being injected when being subjected to body and is being subjected to body that strong the friction evolution of heat and its periphery take place to be subjected to the normal temperature of body the temperature difference to occur, monitor that always the long Infrared Detectors be subjected to body can detect the infrared strong signal that is being subjected to the temperature difference place that occurs on the body in moment, after the computer that this strong signal input is connected with detector carries out the software processing, just can accurately demonstrate the coordinate position that is subjected to the point of impact on the body in the time of both.
Claims (1)
