Abstract

The utility model relates to a target board for shooting, which is used for supersonic speed bullets and subsonic speed bullets in target practice training of pistols and various small arms. The target board has a front bulletproof armor plate, a front and a rear panels and a wooden frame, 3 to 12 sound sensors are installed in different orientations in the wooden frame; the front and the rear panels of the sealed target board take high-elastic materials with favorable sound absorption effect; every sensor is composed of a shell, a metallic membrane and a sensing element; the thickness of the metallic membrane is about between 0.1MUMM and 10MUMM. The utility model has the advantages of strong anti-interference capability, favorable sound absorption effect, less vibration and high reuse rate, and is already applied widely.

Description

The sound automatic target detecting system sealed target board
The utility model belongs to utilization sound and examines the target technology field automatically, relates to a kind of shooting target board that is specially adapted at pistol and various small arms target practice training moderate supersonic speed bullet and subsonic speed bullet.
In the prior art before the utility model, automatically the target-hit of inspection target or the technology of score detecting system adopt photo-electric to hit indicating mode mostly, electricity hits display mode, infrared ray hits indicating mode or the film indication side of taking pictures and shows, corresponding with each technical approach and the design the target board, because of different technology has different materials, structure and surface design, utilization sound is examined the target board of target mode automatically, at the utility model report was arranged once also in the past, for example: in the CN1122445A application for a patent for invention, a kind of " target practice apparatus " disclosed, the target board of this equipment comprises that will be practised an image projection screen in the above, three or more sonic transducer and the framework that the screen surrounding is fixing, sonic transducer is installed on the framework, and with screen as one, screen is made of the soft rubber with very big elongation, and the film that constitutes with cloth or polyester is posted at the back side, has the through hole that allows air outside circulation in the target board on the framework.The target board of this structure, mainly be to be used to train shooter's quick-reaction capability, because complex structure, the cost height, floor space is big, generally is not suitable for colony's Target Practice, Spotting, be not suitable for the weapon running fire yet, and maximum shortcoming is the sonic shock signal that sonic transducer receives, and is subjected to external interference big, the signal to noise ratio height; And for example in the CN1074753A application for a patent for invention, a kind of " the target hit telling system is examined in ball firing automatically " disclosed, on the target board in this system, be provided with vibrating sensor and noise transducer, and be separately fixed on the installing rack around the target surface, this target board is because to survey the moving signal conditioning of noise and vibration measuring different, and the target board guarantees to be easy to receive the structure of two kinds of signals and material characteristics is difficult takes into account simultaneously, thereby make the structure complicated of this target board, poor practicability.
Automatically examine the defective of the prior art of target mode at above-mentioned utilization sound, the purpose of this utility model is, provide a kind of and can overcome above shortcoming, can guarantee when using all kinds of all purpose hand-held weapon, in cavity, can both form high-quality pressure waveform, make sonic transducer can collect this acoustic signals accurately and reliably, the target board is simple in structure, durable in use, can carry out the transmission of signal and data easily, by the automatical and efficient real-time indication of shots target board that computer is accurately located and shown, be used for the target range training of army, People's Armed Police, public security and all kinds of small arms.
Now the utility model technical solution is described below:
Utilization sound is examined the target board in the target technology automatically, the most important thing is to guarantee that acoustic signal propagation is interference-free, reduce sensor and gather the signal to noise ratio of signal, to improve the durable degree of target board simultaneously as far as possible, the utility model has designed a kind of closed target board with noise elimination cavity for this reason, this target board has preceding armour plate, front panel, rear board and wooden frame, the different azimuth of wooden frame inwall, 3-12 sonic transducer is installed, the minimal number of sensor will be as the criterion can form the inconsistent equation group and can find the solution, simultaneously also relevant with the size and the positioning accuracy of frame, when passing the sealing acoustic cavity by measuring bullet, the sound wave that produces affacts the time difference of each sensor, accurately locate by finding the solution the inconsistent equation group, before the sealed target board, rear board, adopt the good highly elastic material of sound-absorbing effect, as rubber slab or high density expanded material plate, sensor and signal cable join, signal cable is positioned in the signal groove of target board lower frame, the two ends of upper and lower side frame be equipped with can regulate fastening before, the spring of rear board; Sensor is to be sound automatic target detecting system target board specialized designs, constitute by housing, metallic membrane and sensing element, metallic membrane is positioned on the upper end of sensing element, and in sensing element is encapsulated in housing, the housing of metallic membrane top has circular hole, the following terminated line of sensing element connects the signal detection special circuit, and the thickness of metallic membrane is between 0.1 μ mm--10 μ mm.
Now that description of drawings is as follows:
Fig. 1: the front elevation of the closed target board of the utility model
Fig. 2: the side view of the closed target board of the utility model
Fig. 3: the profile of the closed target board of the utility model
Fig. 4: the closed target board of the utility model sensor construction figure
Among Fig. 1-Fig. 3, sealed target board is to surround an acoustic cavity (5) by preceding armour plate (1), front panel (2), rear board (3) and wooden frame (4), different azimuth at acoustic cavity (5) inwall is equipped with 3~12 sensors (6), sensor (6) joins with signal cable (7), signal cable (7) is positioned at signal wire slots (8), sealed target board is supported that by support (9) front panel pastes chest silhouette target paper or pastes the TR thin rubber target, and spring (10) is used for regulating fastening front and back panel.
Among Fig. 4, post pole body sensing element is adopted in the visit that metallic membrane (11) places sensing element (12), the utility model, and the top of metallic membrane (11) is facing to the through hole of opening on the housing (13), the below of sensing element is connected to lead (14), joins with power supply and signal deteching circuit (15).
The utility model is compared with prior art, and sealed target board can effectively avoid outside other to do Disturb ripple to the impact of signal detection, can form high-quality pressure waveform, sealed target board front, The rear board sound-absorbing effect is good, shake little, after bullet hits, shell hole can be retracted to less than 1 the milli Rice, can stand the destruction that 6000--20000 sends out bullet, greatly improved the target board repeat make Come to protect with armoring armour plate to part towards bullet, make its firm and durable, not by bullet Hit destruction. In all kinds of small arms trainings of army, People's Armed Police, public security, obtain very at present The good application.
