Description
Technical field
The present invention relates to shoot indication of shots technology, more particularly to a kind of automatic scoring round target device.
Background technology
In army's gunnery training and various physical culture gunnery meetings, indication of shots is the main guarantee work during training and competition
Make.Therefore, the design of scoring round target device is particularly significant.
At present, automatic scoring round target device mainly has following several：
A kind of scoring round target device is, in four frame arrangement semiconductor laser transmitter arrays, to form directional light net, its offside
Arrangement photoelectric receiving tube array, detection gathers system to the photosignal penetrated with one layer of laser net photoelectricity of surface construction before target sheet
System.For example, frame sets multiple semiconductor laser transmitters on top, the photoelectricity for being also provided with equal number in lower frame accordingly connects
Closed tube, equally sets multiple semiconductor laser transmitters in left frame, and the photoelectric receiving tube of equal number is correspondingly arranged on right side,
Each semiconductor laser transmitter one photoelectric receiving tube of unique correspondence, i.e., the laser for being sent from the laser diode can only be by this
Photoelectric receiving tube is received.Bullet incidence during, laser net can be blocked, respectively opto-electronic receiver tube side formed in theory with
Caliber size identical project, by detect this project produce photosignal can determine both horizontally and vertically bullet
Point location coordinate information, so as to obtain including the indication of shots data in number of rings and orientation.But Stimulated Light-emission device physical size is limited,
The density of light net is limited, it is difficult to reach the requirement of precision target precision positioning, and needs generating laser and photoelectric receiving tube one
Penetrate for a pair, its complex structure, practical installation and trial is difficult, the laser of substantial amounts is with high costs, and shortcoming is obvious.
Another scoring round target device forms sector optical curtain and illuminates detection method using multilayer laser line light source, by opto-electronic receiver
Device array quadrature arrangement is L-shaped, and installs line source illumination laser, the photoelectric receiving device and line in the diagonal other end
Light source illumination laser is one group.Also, the scoring round target device needs two groups of photoelectric receiving device array vertical symmetries to set to form U
Shape, and the front and rear distance that staggers.Correspondingly, it is also desirable to two line source illumination lasers.During bullet incidence, line source shape
Into sector optical curtain be blocked, form corresponding projected segment on the L-shaped photoelectric receiving tube array of offside respectively, and produce photoelectricity
Signal.Its two groups of data of photoelectric receiving device array detection need to can just obtain the two-dimensional position coordinate of bullet through complex calculation.
And a certain distance that staggers before and after this two groups of photoelectric receiving device array detection devices palpuses, to avoid interfering.Due to using
Two groups of photoelectric receiving device arrays of L-shaped arrangement, its structure is equally complicated, and debugging is difficult, relatively costly.Bullet is through preceding
The difference of incident angle can cause measurement error to increase during two-layer light curtain afterwards.According to bullet projection is formed through multi-layer sector optical curtain
The position of section needs the complex calculation just to calculate point of impact location coordinate information, it is necessary to by powerful arithmetic processor such as platform
Formula machine, notebook computer etc., are unfavorable for the mobile and miniaturization of hit telling system, also improve holistic cost.
