Technical Field

[0001] The utility model relates to the technical field of military and police live ammunition design training equipment, and particularly relates to an automatic target reporting device for multi-target observation. Background Art

[0002] At present, most of the target reporting devices on the market are laser automatic up-and-down targets, such as the fixed high-precision shock wave target produced by Hebei Zhidun Technology Co., Ltd. This type of up-and-down target is only applicable to training grounds and not suitable for the field training environment of soldiers. Its environmental adaptability is limited and it is greatly affected by light. In strong light, the laser signal may be interfered, resulting in inaccurate target reporting. Moreover, a single set of devices can only be applicable to one target and not suitable for multiple target positions, and the layout and maintenance costs are relatively high. To solve the above problems, an automatic target reporting device for multi-target observation is proposed. Summary of the Utility Model

[0032] Combined with Figures 1 to 6 Describe this implementation method. An automatic target reporting device for multi-target observation includes a target search and reporting camera system 10, a lithium battery 21, and a bulletproof steel plate assembly 30. During use, first place the target search and reporting camera in the target area, place the lithium battery at the back, then overlap three sides of the bulletproof steel plate assembly, then magnetically attach the two antennas of the target search and reporting camera to the base of the bulletproof steel plate assembly, and finally overlap the top surface of the bulletproof steel plate assembly.

[0033] The target search and reporting camera system 10, as the core subsystem of the system, can simultaneously perform target search and recognition operations on 5 groups of target targets. The structure is designed with separate compartments, and the housing is divided into a combined design of Compartment A and Compartment B. The main function of Compartment A is image acquisition. The outermost surface of Compartment A is a double-layer single-transparent glass component. The single-transparent glass is closer to the camera side in this component, and the outer layer is an acrylic baffle. This baffle ensures that the surface of the internal single-transparent glass is not scratched and the surface cleanliness, and at the same time prevents the possibility of human damage.

[0034] As Figures 2 to 4 shown, a refrigerator assembly 12 is installed inside Compartment A. Because the structure of Compartment A is closed, a refrigerator mechanism is used for refrigeration and heat dissipation. The structural framework is supported by a support steel frame 14. All large-load components of this system are fixed on the support steel frame. The surface of the steel frame is covered with structural surface sheet metal 16, and handles 15 are symmetrically arranged on the housing to facilitate the transportation of the structure. A rubber shock-absorbing layer 17 is installed at the bottom of the housing to prevent vibration during vehicle transportation and the impact of soldiers on the ground.

[0035] In this embodiment, in order to reduce the overall size of the target-seeking and target-reporting camera system, 5 sets of zoom cameras adopt a 3+2 layout, as shown in Figure 4 the figure. That is, there are 3 sets of camera pan-tilt assemblies 11 and 2 sets of flexible-leg camera pan-tilt assemblies 13 respectively.

[0036] Each set of the camera pan-tilt assembly 13 with flexible legs includes a camera pan-tilt assembly 11 and a camera flexible leg 131 mounted on the turntable fixed frame 111 at the bottom of the camera pan-tilt assembly 11; the camera flexible leg 131 is mounted on the rubber shock-absorbing layer 17 through the structural surface sheet metal part 16.

[0037] Each set of the camera pan-tilt assembly 11 includes a bottom turntable fixed frame 111, an L-shaped connecting plate 112, a pitching turntable 113, a camera fixed frame 114, a zoom camera 115 and a horizontal turntable 116;

[0038] The bottom turntable fixed frame 111 is used to fix the horizontal turntable 116. At the same time, the bottom turntable fixed frame is installed on the top surface of the lower camera flexible leg 131. The top rotating surface of the horizontal turntable is connected to the rotating surface of the pitching turntable 113 through the turntable L-shaped connecting plate 112. The L-shaped connecting plate is also connected to the camera fixed frame 114, and the camera fixed frame is used to fix the zoom camera 115. The camera pan-tilt assembly drives the L-shaped connecting plate through the pitching turntable, and then drives the zoom camera 115 to perform pitching motion. The horizontal turntable 116 drives the L-shaped connecting plate, and then drives the zoom camera 115 to perform horizontal rotation motion.

[0039] In this embodiment, the camera pan-tilt assembly 13 with flexible legs only has an additional bottom camera flexible leg 131 structure compared with the camera pan-tilt assembly 11, which is used to increase the longitudinal height of the zoom camera 115 and avoid interference during the operation of the structure. The 2 sets of cameras are arranged at the rear of the 3 sets of cameras, that is: the bottoms of the 2 sets of cameras at the rear are integrated with flexible leg structures. Through the flexible structure design, the influence of vehicle transportation and ground impact on the camera measurement imaging is avoided. There is one set of zoom camera on each set of pan-tilt assemblies, that is, 5 sets of zoom cameras. Each set of zoom cameras has two degrees of freedom, that is: the pitching degree of freedom and the rotation degree of freedom are realized through the pitching turntable 113 and the horizontal turntable 116 respectively. Each set of turntables is driven by an internal motor driver to rotate the rotating surface, and a position sensor is integrated inside, and its angle control accuracy can reach 0.001°.

[0040] Taking Figure 2The view directions, from left to right, respectively define the camera numbers as 01 - 05. In the actual shooting range environment, the distance between adjacent target targets is 2 - 4m. Set the horizontal turntable rotation angle of No. 01 to be -40° to 0°. The horizontal turntable rotation angle of No. 02 is -25° - 0°, the horizontal turntable rotation angle of No. 03 is ±15°, the horizontal turntable rotation angle of No. 04 is 0° - 25°, and the horizontal turntable rotation angle of No. 05 is 0° - 40°. The pitch angles of cameras 01 - 05 are ±20°.

[0041] As Figure 5 shown, cabin B is mainly responsible for image data processing, and a refrigeration fan assembly 18, an industrial control computer 19, and a switch 20 are installed inside it.

[0042] The switch 20 provides multiple network ports, which can connect 5 sets of zoom cameras to the industrial control computer 19 to realize the transmission of images from the 5 sets of zoom cameras to the industrial control computer 19, and the images are processed and analyzed on the industrial control computer 19. The refrigeration fan assembly 18 is composed of two silent bearing fans with a fan speed of 2400PRM, which are distributed on both sides of cabin B to drive the air flow between cabin B and the outside to form a circulating wind field, continuously dissipating heat for the industrial control computer 19 and the switch 20.

[0043] In this embodiment, the lithium battery 21 is used as an external power supply. This set of system uses an outdoor power supply with a peak output power of 2600W and a capacity of 1024Wh to provide stable power supply for the target - seeking and target - reporting cameras.

[0044] As Figure 6 shown, it is the assembly drawing of the bullet - proof steel plate assembly. The bullet - proof steel plate assembly 30 provides protection for the target - reporting camera system to prevent soldiers from accidentally hitting the target - seeking and target - reporting camera system 10 and the lithium battery 21 with bullets during target shooting, which may cause hazards such as explosion.

[0045] The bullet - proof steel plate assembly 30 includes a right - hand bullet - proof steel plate 31, a top bullet - proof steel plate 32, a left - hand bullet - proof steel plate 33, and a tail bullet - proof steel plate 34. Among them, the right - hand bullet - proof steel plate 31 and the left - hand bullet - proof steel plate 33 have the same structure, each having three legs. The legs are made of 45 - steel material with a thickness of 6mm, and a number of φ3*10mm oblong holes are laser - processed on the plate surface to provide heat dissipation and signal transmission for the target - seeking and target - reporting cameras.

[0046] The top bulletproof steel plate 32 has a thickness of 3 mm, and a number of oblong holes with a diameter of φ3 * 10 mm are laser machined on the plate surface to provide heat dissipation and signal transmission for the target-seeking and target-reporting camera. The tail bulletproof steel plate 34 has a thickness of 3 mm and has two legs. Since its surface directly faces the soldiers and has the highest probability of being hit by bullets, no punching is done on this surface. The bulletproof steel plate assembly 30 adopts the design concept of an insertion plate structure. The whole bulletproof steel plate assembly is formed by mutually inserting 4 steel plates. During use, the right bulletproof steel plate 31 is inserted into the corresponding slot of the tail bulletproof steel plate 34 and then overlapped downward, and then the left bulletproof steel plate 33 is inserted into the corresponding slot of the tail bulletproof steel plate 34 and then overlapped downward. Finally, the top bulletproof steel plate 32 is respectively inserted into the top rectangular raised blocks of the right bulletproof steel plate 31, the left bulletproof steel plate 33, and the tail bulletproof steel plate 34. Thus, the four bulletproof steel plates are fully fixed. The 4 steel plates can be independently replaced and maintained for each part. When any steel plate has a problem, it can be replaced in time for easy repair. The steel plates are made of special bulletproof steel, and the surface of the steel is hot-dip galvanized, which can enhance the corrosion resistance and strength of the structure and can be used for a long time in harsh environments.

[0047] The target-reporting device described in this embodiment should be placed at the center of 5 target targets, 10 - 15 m directly in front of the target position of target 3. The horizontal position deviation of the target-seeking and target-reporting camera system from target 3 is controlled within ±1 m, and the horizontal tilt angle of the target-seeking and target-reporting camera system with respect to target 3 can meet the automatic target-reporting function when it is not greater than 30°.

[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0049] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
