Abstract

The utility model relates to an electronic target surface sensor with the function of automatic electronic target reporting. The electronic target surface sensor comprises an insulation board, a conductive rubber slice filled with carbon black, a connecting lead and five pulse shaping circuits, wherein the conductive rubber slice filled with carbon black with the thickness of 1mm to 2mm is adhered on the back side of the insulation board, five concentric rings with same width and texture (namely conductive rubber slice filled with carbon black) with a standard target surface are adhered on the front side of the insulation board, the target surface center adopts 10 rings, and the rest respectively sequentially adopt 9 rings, 8 rings, 7 rings and 6 rings from inside to outside, each ring on the front side of the target and the conductive rubber on the back side of the target are all respectively connected with the corresponding input ends of the five shaping circuits through the connecting wire, and the output ends of the five pulse shaping circuits are connected with the input ends of subsequent processing circuits. The electronic target surface sensor is applied to an automatic electronic target-reporting device in an infantry live-shell shooting range, and also can be applied to such as devices used for non-live shell stimulation shooting training, aiming exercise of new recruits and entertainment shooting game occasion after being slightly improved.

Description

A kind of electric target face sensor

Technical field

The utility model relates to a kind of electric target face sensor of electronics automatic target-indicating.

Background technology

Existing target surface sensing device, its conducting surface adopts copper sheet to make more, elasticity is little because these metals are softer, when bullet passes target surface, conductive metal sheet easy deformation and cause the permanent short circuit of target surface, at this moment, still can carry out in order to guarantee to practice shooting to train, with regard to needing artificial short circuit partly to separate to target surface, not only time-consuming, and also sharp metal breach also may cause repairman's hand injured.

Summary of the invention

The purpose of this utility model is to provide a kind of novel electron target surface sensor, and there is the target surface short circuit problem never in it, and does not consume metallic copper, and the target process is changed in the craft that can solve the wasting of resources and trouble, raises the efficiency.

The technical scheme that the utility model adopted is: the electric target face sensor is made of jointly insulation plank, carbon black filled conductive rubber slice, connection lead and five pulse shapers; Paste the carbon black filled conductive rubber slice of 1～2 millimeter of a layer thickness at the back side of insulation plank, five donuts that positive stickup is identical with standard target surface ring width, quality is all carbon black filled conductive rubber slice, its center is 10 rings, be followed successively by 9 rings, 8 rings, 7 rings, 6 rings from inside to outside, each ring of the front of target all is connected with five shaping circuit corresponding input end respectively by being connected lead with the conductive rubber at the back side, and the output of five pulse shapers links to each other with the input of subsequent process circuit.

Described connection lead is made up of multiply dead-soft thin copper wire and pin, pin is welded on of multiply dead-soft thin copper wire with scolding tin, pin directly inserts in the corresponding conductive rubber slice, and multiply dead-soft thin copper wire then links to each other with the corresponding input end of pulse shaper.

The utility model is applicable on the electronics automatic scoring round target device in infantry's ball firing field and uses, and also can be used for non-live shell pattern stimulation shooting training, new recruit's aiming exercise after making improvements slightly, and on the device such as entertaining shooting recreation occasion.Have operation accurately and reliably, low price is safeguarded simple advantage.

The specific embodiment

As shown in Figure 2, insulation plank 2 adopt three ply boards, fiberboard or common plank, as long as thickness be no more than 5 millimeters and insulating properties well all can, the size that cuts required target surface keeps part to also needing to insert underground wood.Cut identical with the target surface size, thickness is 1～2 millimeter carbon black filled conductive rubber slice 1, stick on the back side of target plate with double-sided adhesive, use the same method then, cut earlier and the identical conductive rubber ring 3 in target surface 6,7,8,9,10 five rings, and they are sticked on respectively on the positive corresponding position of target plate with double-sided adhesive.

The lead-in wire method of each ring all adopts the contact pin method, earlier the stranded lead that forms of multiply dead-soft thin copper wire is welded on the pin with scolding tin, such lead needs 6, syringe needle is inserted on the conductive rubber of corresponding ring, and the input of corresponding monostable circuit is inserted in the other end of lead, the input of the exit order steady-state circuit A10 of positive 10 rings of target plate; The input of the exit order steady-state circuit A9 of 9 rings; The input of the exit order steady-state circuit A8 of 8 rings; The input of the exit order steady-state circuit A7 of 7 rings; The input of the exit order steady-state circuit A6 of 6 rings; And the exit ground connection at the target plate back side, as shown in Figure 1.And output is input among the digital processing circuit B as input signal through shaped pulse signal again from A10 to A6, thereby has constituted complete electronics hit telling system, has realized just demonstrating rapidly after target practice the number of rings and the score counting situation that hit.

The carbon black filled conductive rubber that thickness in the embodiment is 1～2 millimeter has market product, can directly buy, and mature 555 monostable circuits on A10, A9, A8, A7, the A6 employing market, or TTL in addition, CMOS monostable integrated circuit all can.Digital processing circuit B can be by encoder, and the decoder sum counter combines (being prior art).

During ball firing, when utilizing metal bullets to pass target surface, short circuit is affixed on the conductive rubber on plank two sides and the microsecond level burst pulse that forms is taken out as the signal that hits, and is input to after monostable circuit is shaped as 0.1 second broad pulse then in the digital governor circuit system, as shown in Figure 3.Because there is elasticity in conductive rubber slice, so the conductive rubber slice on plank two sides can not cause the two sides short circuit with pop into position behind the bullet puncture target.
