Abstract
The invention belongs to the photo-electric hit-detector.The present invention can be round-the-clock, continuous, be recycled and reused for that bullet to various rifles and cannon carries out single-shot, running fire test and to the shell of all size, (test the speed) when the bomb blast fragment is surveyed, thereby calculate the shell of all size, the brisance of bomb.The present invention is made up of target holder, splinter shield, and array light source, twin-lens receiver are housed on target holder.Constitute light curtain (optical screen) by array light source and twin-lens receiver.
Description
The present invention is that a kind of bullet that is used for various rifles and cannon carries out single-shot, running fire test and to the shell of all size, the light curtain target that (tests the speed) when the bomb blast fragment is surveyed, belongs to hit-detector.
At present, target range employed " target " is disposable consumption equipment mostly, expended great amount of manpower and material resources in the use.Existing canopy of the heavens target, when the mistake target that is used for single bullet on the trajectory is surveyed (testing the speed), though can be repeatedly used, but for the shell of all size, (testing the speed) and follow-on test when the bomb blast fragment is surveyed, cause is limited to the strong jamming of instant of detonation and is subjected to the influence of climate change, remain in some difficulties, and involve great expense.From to the relevant retrieval of patent both at home and abroad, only find CN.85107388A, US.3,627,323, US.3,778,059 three patents relevant with the technology of the present invention background are so the present invention has novelty, creativeness.
The objective of the invention is to bullet round-the-clock, continuous, that be recycled and reused for various rifles and cannon and carry out single-shot, running fire test and to the shell of all size, (test the speed) when the bomb blast fragment is surveyed, thus calculate the brisance of all size shell, bomb.
The objective of the invention is to realize with following technical proposals.As shown in Figure 1, the present invention is made up of target holder [3] and the splinter shield [4] that is contained in target holder [3] upper edge, an array light source [1] is housed in target holder [3] upper side frame and on target holder [3] lower frame, a twin-lens receiver [2] is housed, constitute light curtain (optical screen) [5] or be called effective light curtain by array light source [1] and twin-lens receiver [2].Array light source [1] has a luminous array, and its luminous array is made up of the bulb with light gathering, and is furnished with corresponding guiding mechanism, makes it to form satisfactory bar shaped array light source.At the twin-lens optical system end of twin-lens receiver [2], has the phototriode array of two equal lengths, equal-order digits.At the front end of the twin-lens optical system of twin-lens receiver [2], have one and regulate the light hurdle, a contraposition guiding mechanism is housed below its phototriode array.Array light source [1] is through the adjusting light hurdle and the twin-lens optical system of twin-lens receiver [2], just form the luminous point array of two equal lengths, equal-order digits, again by its contraposition guiding mechanism, make the luminous point array respectively with two equal lengths, etc. the phototriode array of group number overlap.Like this, array light source [1] and twin-lens receiver [2] constitute optical screen (being light curtain [5]).Twin-lens receiver [2] also has the high sensitivity fast signal treatment circuit of anti-strong jamming, strong vibration impact.When bullet or fragment pass light curtain [5], owing to instantaneously blocked a part of light, cause the change of some responsive first state on the phototriode array, i.e. photosignal is born in sense (product).This photosignal of inducting amplifies through signal processing circuit to be handled, and just forms the required standard operation signal of instrument, supplies to show, writes down and be transferred to system's stream when surveying.
Advantage of the present invention is as follows, owing to adopted the technical scheme of above-mentioned optoelectronic integration of machine, making can be round-the-clock, continuous, be recycled and reused for that bullet to various rifles and cannon carries out single-shot, running fire test and to the shell of all size, (test the speed) when the bomb blast fragment is surveyed.The present invention adopts the very high photoelectric receiving device of frequency response, and is furnished with the fast signal treatment circuit, so to measuring bullet, the traverse velocity of fragment all has good response, and can reliablely and stablely work.

Embodiment:
As shown in Figure 1, form luminous array by 100 bulbs with light gathering, through its guiding mechanism, make it to form bar shaped array light source [1], adjusting light hurdle by twin-lens receiver [2] and twin-lens optical system form the luminous point array of two equal lengths, equal-order digits, again by its contraposition guiding mechanism, make the luminous point array respectively with two equal lengths, etc. the phototriode array of group number overlap.Array light source [1] and twin-lens receiver [2] constitute light curtain [5] like this.When bullet or fragment are worn light curtain [5], owing to instantaneously blocked a part of light, cause the change of some responsive first state on the phototriode array, promptly generate photosignal.This photosignal of inducting amplifies through signal processing circuit to be handled, and just forms the required standard signal of instrument, supplies to show, writes down and be transferred to system when surveying.Signal processing circuit as shown in Figure 2, wherein: phototriode group [1], [2] ...
