Fig. 1 shows an embodiment of the present invention provides a simulated three-dimensional target for implementing target-reporting in multiple positions, which includes a three-dimensional target 1 and a base 2. The three-dimensional target 1 is made of plastic materials with certain rigidity, and the whole appearance of the target is formed. The target is located base 2, and three-dimensional target 1 is the cavity type, and inside is divided into left side cavity 13 and right side cavity 12. Fig. 2 is a front structure (cross section) of the three-dimensional target 1 of the present embodiment, wherein the inner partition 11 divides the whole target cavity into two parts, namely a right cavity 12 and a left cavity 13; wherein the right cavity 12 is communicated with the head cavity to form a sound guide cavity. In the embodiment, the height measurement of the impact point is realized by using the approximately cylindrical sound guide cavity formed by the shell of the three-dimensional target 1 and the inner interlayer, so that the detection of the hit part is realized.

In some embodiments, the interior wall of the target cavity is coated with a sound absorbing material, such as a sound absorbing sponge 14, for absorbing the sound wave energy generated by the impact of a bullet on the target cavity shell and eliminating interference with shock wave detection.

As shown in fig. 2 and 3, the base 2 is provided with a plurality of vibration sensors 3, at least one ultrasonic sensor 4 and a signal processing unit 6, and both the vibration sensors 3 and the ultrasonic sensors 4 are connected with the signal processing unit 6. Preferably, the signal processing unit 6 is fixed under the base 2.

Specifically, as shown in fig. 3, four vibration sensors 3 are arranged on the bottom of the target cavity and the base 2, and are respectively arranged in the front, rear, left and right directions of the target, and an ultrasonic sensor 4 is respectively arranged at the bottom of the left cavity 13 and the right cavity 12 and is used for detecting shock signals generated in the air of the cavity when a bullet penetrates into the cavities. All the sensors are connected with the signal processing unit 6 through cables, detection signals are subjected to detection, filtering, sampling, time difference calculation and other processing by the sensors, the arrival time difference of the signals of the sound guide cavities is substituted into a calculation model, and finally a judgment result is generated.

In the above embodiment, the half-body three-dimensional target is divided into the left and right independent sound guide cavity structures, the ultrasonic sensor 4 and the vibration sensor 3 are respectively arranged at the bottom of the cavity, and the hitting area and the bullet attack direction are determined by calculating and analyzing the signal arrival time difference between the sound guide cavities.

The simulated three-dimensional target of the embodiment is provided with an integrated base, and has the main functions of fixing the target, installing the sensor and providing switching for installation with an application platform. As shown in fig. 3, the base 2 includes a patch 22 and a bottom plate 21, wherein the patch 22 is a frame structure and is fixed on the bottom plate 21. The base plate 21 and the lining 22 are preferably made of an aluminum alloy. Specifically, the vibration sensors 3 are located on four side frames of the lining 22, and are optionally fixed by a clamping mechanism 5, as shown in fig. 3, the clamping mechanism 5 includes vertical clamping portions and a shaft penetrating through the clamping portions, the rotating shaft enables the distance between the clamping portions to be adjustable, and the vibration sensors 3 are located at the top end of the shaft.

The ultrasonic sensor 4 is fixed on the bottom plate 21, is positioned in the frame of the lining 22, is respectively positioned at the bottom of the left cavity 12 and the right cavity 11, and is used for detecting shock wave signals generated in the air of the cavities when bullets penetrate into the cavities.

In some embodiments, a shock-absorbing washer 23, optionally a rubber shock-absorbing washer, is disposed between the contact surface of the lining 22 and the bottom plate 21, so that the lining 22 can fix the target on the bottom plate 21 by the rubber shock-absorbing washer and the screw with a rubber bushing to eliminate the influence of the vibration signal when the mobile platform moves on the signal detection. The three-dimensional target 1 and the base 2 adopt structures convenient to disassemble and assemble, and the target can be quickly replaced.

The implementation method using the embodiment is as follows: when a bullet hits a target from a certain direction, a hard shell of the target cavity is excited to generate a vibration signal, and the vibration signal is transmitted to the periphery along the shell of the target cavity at a speed V by taking a hit point as a center; meanwhile, when the bullet penetrates into the shell, a shock wave signal is generated in the air of the cavity at the moment, and the shock wave signal is transmitted downwards along the sound guide cavity at a speed mu by taking the hit point as a starting point; since the speed V of the vibration signal propagating in the plastic medium is much higher than the speed mu of the shock wave propagating in the air, a certain vibration sensor 3 (the one closest to the hit point) installed at the bottom of the target cavity will receive the vibration signal first, and the arrival time of the vibration signal is defined as T1; then, the shock wave signal in the sound guide cavity is detected by the corresponding ultrasonic sensor 4, and the arrival time of the shock wave signal is defined as T2; therefore, the arrival time difference Δ T of the two signals is T2-T1, so that the height H Δ T · V μ/(V- μ) of the bullet hitting the sound guide cavity can be obtained, the hit specific part can be determined by combining the hit target cavity division, and meanwhile, the attack direction of the bullet can be roughly determined by the sequence of the vibration signals received by the vibration sensors 3 located at different positions (the installation direction of the sensor which receives the vibration signal first is the attack direction of the bullet).

As shown in fig. 4, the determination of the hit portion may be performed as follows:

1. when the bullet hits the left lateral acoustic cavity:

1) when H is more than or equal to 0 and less than L1, judging the other is judged;

2) when the L1 is more than or equal to H and less than L2, the abdomen is judged;

3) when L2 is more than or equal to H < L5, judging the breast;

4) and when L5 is less than or equal to H less than or equal to L6, the head is judged.

2. When the bullet hits the right side acoustic cavity:

3) when L2 is more than or equal to H < L5, judging the breast;

4) when L3 is more than or equal to H and less than or equal to L4, the heart is judged;

3. when the bullet passes through the double-side sound conducting cavity simultaneously:

3) when L2 is more than or equal to H < L5, judging the breast;

5) and when L5 is less than or equal to H less than or equal to L6, the head is judged.

Wherein L1 is the height from the base to the part below the waist and abdomen, L2 is the height from the base to the waist and abdomen, L3 is the height from the base to the part below the heart, L4 is the height from the base to the part below the heart, L5 is the height from the base to the part below the head, and L6 is the height from the base to the head.

Above judge that when the position that two side sound conduction chambeies were judged is different, the priority of judging is: head > heart > chest > abdomen > others.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
