The output signals of the four pairs of acoustic sensors are transmitted to the computer automatic target reporting system through the signal amplification and filtering circuit, the analog-to-digital conversion, and the data acquisition circuit. The patent also discloses the principle of acoustic measurement: four pairs of acoustic sensors are arranged in a rectangular shape around the shooting area, and the coordinates of the hit point can be obtained by the following method: one pair of acoustic sensors is defined as the first sensor 1, the acoustic sensor on the same short side as the first sensor 1 is defined as the second sensor 2, the acoustic sensor diagonally opposite to the first sensor 1 is defined as the third sensor 3, and the acoustic sensor on the same long side as the first sensor 1 is defined as the fourth sensor 4. The coordinates of the hit point are obtained by the following formula: x = (Vel*Vel*t4*(t2*t2+t3*t4-t2*t4-t3*t 3)+LENGTH*LENGTH*(t2+t4-t3)) / (2*LENGTH*(t2+t4-t3)(Vel*Vel*t2*(t4*t4+t3*t2-t2*t4-t3*t3)+WIDTH*WIDTH*(t2+t4-t3)) / (2*WIDTH*(t2+t4-t3)), where: x and y are the horizontal and vertical coordinates of the hit point with the first sensor 1 as the origin, the long side as the horizontal axis, and the short side as the vertical axis; Vel=340m / s is the speed of sound propagation in air; t2, t3, t 4 is the time difference between the time when the second sensor 2, the third sensor 3, and the fourth sensor 4 receive the sound signal and the time when the first sensor 1 receives the sound signal t1; LENGTH is the distance of the long side; WIDTH is the distance of the short side. The sound sensor in the above invention is an ultrasonic sensor, which can effectively eliminate the interference of man-made noise. CN200610102134.X discloses a shock wave target reporting system, which consists of an upper computer and a lower computer; the upper computer and the lower computer are connected by wireless communication; the lower computer consists of a T-shaped array shock wave sensor group, a microprocessor, and a wireless data transmission module; the T-shaped array The shock wave sensor group is composed of four shock wave sensors Q1, Q2, Q3, and Q4. The T-shaped array shock wave sensor group is located at the lower or upper part of the target plane. The output ends of the four shock wave sensors are connected to the input end of the microprocessor, and the microprocessor is connected to the wireless data transmission module. The host computer is composed of a wireless data transmission module, a computer, and a display. The wireless data transmission module is connected to the computer, and the output end of the computer is connected to the display. The shock wave sensors Q1, Q2, and Q3 are located on the same horizontal line, and the shock wave sensor Q1 is located at the midpoint of the shock wave sensors Q2 and Q3, and the shock wave sensor Q4 is located directly below the shock wave sensor Q1.It consists of two parts: an upper computer and a lower computer; the upper computer and the lower computer are connected through wireless communication; the lower computer consists of a T-shaped array shock wave sensor group, a microprocessor, and a wireless data transmission module; the T-shaped array shock wave sensor group consists of four shock wave sensors Q1, Q2, Q3, and Q4, and the T-shaped array shock wave sensor group is located at the lower or upper part of the target plane; the output ends of the four shock wave sensors are connected to the input ends of the microprocessor, and the microprocessor is connected to the wireless data transmission module; the upper computer consists of a wireless data transmission module, a computer, and a display; the wireless data transmission module is connected to the computer, and the output end of the computer is connected to the display. The shock wave sensors Q1, Q2, and Q3 are located on the same horizontal line, and the shock wave sensor Q1 is located at the midpoint of the shock wave sensors Q2 and Q3, and the shock wave sensor Q4 is located directly below the shock wave sensor Q1. The distance between the shock wave sensor Q4 and the shock wave sensor Q1 is less than or greater than the distance from the shock wave sensor Q2 to Q1. Each shock wave sensor is composed of an ultrasonic probe, an amplifier circuit, a bandpass filter circuit, and a comparison circuit; the output end of the ultrasonic probe is sequentially passed through the amplifier circuit, the band manual 1 / 5 page 4CN 212620387 U4.

[0003] The filter circuit is connected to the input end of the comparison circuit, and the output end of the comparison circuit is connected to the input end of the microprocessor. Point P is the impact point, and its coordinates are P(x, y); the coordinates of the four shock wave sensors are: Q1(0, -c), Q2(-2c, -c), Q3(2c, -c), Q4(0, d); wherein d<c. The sizes of the above c and d are set according to the size of the target. The working principle is as follows: According to the shock wave generated by the projectile fired from the gun flying in the air, the shock wave is captured by the shock wave sensor array, and the time to reach each shock wave sensor is calculated by the microprocessor, and uploaded to the computer by wireless transmission. According to the T-shaped array of the shock wave sensor and the time when the shock wave reaches each sensor, the coordinates of the impact point are calculated and converted into the number of target position rings. In this embodiment, the shock wave diffusion velocity can also be actually measured and accurately corrected in real time;

[0004] The above contents are all the existing technologies of shock wave target reporting. In fact, shock wave target reporting is very simple. In summary, the shock wave sensor cooperates with the target body. When the bullet warhead flies in the air, due to the compression of the surrounding gas by the high-speed moving warhead, a cylindrical weak shock wave will be formed to spread around. The characteristic value of the compression wave is measured by the sensor arranged under the target plate, and the data acquisition device encodes it and transmits it to the data control system via wired or wireless mode. Finally, the position of the impact point is displayed on the display, and the target is reported in two ways: voice and image. There are many improvements in the existing technology for shock wave target reporting, and the existing shock wave target reporting technology is updated relatively quickly. However, most of the current shock wave target reporting systems have rarely been improved in structure. The current shock wave target reporting system is large in size, difficult to install, difficult to move, and not convenient to carry. Furthermore, due to structural problems, the shock wave target reporting system is not convenient to use. Although there are also independent and compact shock wave target reporting systems on the market, the target body of this shock wave target reporting system is small and cannot meet the needs of most people for shooting together. Therefore, in view of this, the inventor proposes a portable shock wave target reporting system. Summary of the invention

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] The reference numerals in the drawings of the specification include: a cart body 1, a target body 2, a hinge rod 201, a hinge point 202, a plug column 203, a plug rod 204, a socket 205, a clamping plate 3, a fixing rod 4, a push handle 5, a vertical rod 6, and a mounting body 7.

[0028] Implementation example Figure 1 , Figure 2 and 3 As shown:

[0029] A portable shock wave targeting system, comprising a shock wave targeting assembly and a transport assembly for portable transport of the shock wave targeting assembly;

[0030] Specifically: The shock wave target reporting component also needs to be equipped with a platform and a data recording platform to implement assessment and scoring to facilitate training;

[0031] The shock wave target warning assembly includes a plurality of overlappable target bodies 2, a mounting body 7 disposed at the bottom of the target body 2, a secondary target body 2 mounted between the stretched target bodies 2, and a shock wave sensor disposed inside the mounting body 7 for cooperating with the target body 2. The mounting body 7 is located at the position of the secondary target body 2 and is provided with a socket 205 for electrical connection of the secondary target body 2. The length of the mounting body 7 is greater than the length of the target body 2.

[0032] Transport component: includes a cart body 1 , a first portable component for placing a target 2 , and a second portable component for placing a secondary target 2 .

[0033] like Figure 2As shown, a hinge rod 201 is provided between adjacent target bodies 2, and there are two hinge points 202 of the hinge rod 201, which are respectively arranged on the back of the previous target body 2 and the front of the next target body 2. The hinge rod 201 is provided with a mounting assembly for mounting the secondary target body 2. The hinge rod 201 can be used to pull the adjacent target bodies 2 apart so that the target bodies 2 are in the same plane. The mounting assembly includes a mounting hole opened in the center of the hinge rod 201, a plug column 203 installed in the mounting hole, a socket opened around the plug column 203, a plug rod 204 detachably connected to the socket, and a limit rod arranged at one end of the plug rod 204 away from the mounting hole. Specifically: the plug rod 204 is inserted into the socket to form a cross structure, and the four end faces of the secondary target body 2 are wrapped and fixed by the cross structure and the limit rod. After the power connection point at the bottom of the secondary target body 2 is inserted into the socket 205, it shares the same shock wave sensor with the target body 2.

[0034] like Figure 3 As shown, the distance between the auxiliary target body 2 installed between the target bodies 2 and the adjacent target body 2 is 2 mm. 2 mm is the size of the limit rod, the left end of the limit rod contacts the target body 2, and the right end of the limit rod contacts the auxiliary target body 2.

[0035] The first portable component includes a placement groove opened on the cart body 1 for placing the target body 2, a cylinder symmetrically arranged on the inner wall of the placement groove and a clamping plate 3 installed at the protruding end of the cylinder, the clamping plate 3 is in contact with the side wall of the target body 2, and the side walls of the target body 2 are all provided with grooves. After the target body 2 is flatly placed, the grooves form a fixed groove, the fixed groove is the same as that of the clamping plate 3, and the height of the groove is higher than the height of the clamping plate 3.

[0036] Specifically: the second portable component is two fixed rods 4 that overlap each other up and down and are arranged on the cart body. The fixed rods 4 are provided with connecting grooves, and the connecting grooves are used to vertically place the auxiliary target body 2.

[0037] About the cart body: the cart body is located at the top of the fixed rod 4 and is equipped with a push handle 5. Specifically: vertical rods 6 are provided at both ends of the fixed rod 4, and the push handle 5 is installed on the vertical rods 6. The push handle 5 is provided with a mesh anti-slip pattern; the cart body is located at the bottom of the placement groove and is evenly equipped with a number of moving wheels, and the moving wheels are moving wheels with brake pads.

[0038] Specific implementation process:

[0039] First of all, the first point of this system is to build the shock wave sensor into the mounting body 7, making the appearance more beautiful. Then, the shock wave sensor has many serial points, which are used to connect all the targets 2 and the auxiliary targets 2, and then connected to the data recording platform, and the shock wave target reporting system is completed;

[0040] If this system is not used: Figure 2As shown, the target body 2 is overlapped on the left and right sides by using the hinge rod 201, and the staff are asked to lift it up and put it into the placement groove, start the cylinder, change the position of the clamping plate 3, so that the clamping plate 3 and the groove are combined accordingly, and the clamping plate 3 and the groove are used to fix the target body 2 and change the height of the target body 2, so that the cart body can be used to achieve portable movement. The same is true for the auxiliary target body 2: since the auxiliary target body 2 and the target body 2 in this system are not integrally formed, therefore, if not used, the auxiliary target body 2 needs to be stored separately and placed in the connecting groove, and fixed in place using the connecting groove.

[0041] If the system needs to be used: the following steps are performed: the target body 2 is unfolded: the target body 2 is unfolded using the hinge rod 201, the insertion rod 204 is installed using the hinge rod 201 and the mounting hole, and then the insertion holes are opened around the insertion rod 204, and the insertion rod 204 and the limit rod set at the outer end of the insertion rod 204 away from the mounting hole are inserted into the insertion holes. Specifically: the insertion rod 204 is inserted into the insertion hole to form a cross structure, and the four end faces of the auxiliary target body 2 are wrapped and fixed by the cross structure and the limit rod;

[0042] Then the auxiliary target body 2 and the target body 2 can form a long screen, and the target reporting can be realized by cooperating with the shock wave sensor and the data recording platform.

[0043] This system solves the problem of low portability of traditional shock wave target reporting systems.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
