Description

TECHNICAL FIELD

[0001] The utility model relates to laser protection matching equipment technical field, especially in all-weather laser protection system. BACKGROUND

[0002] Laser protection system, also known as laser shield, is a kind of weapon defense barrier formed by high-energy laser beam, aiming at resisting the attack threat of enemy to own target, which has the advantages of rapid response, high precision, low cost and the like.

[0003] Specifically, the laser protection system uses the high energy density and rapid response capability of laser beam to carry out accurate attack or interference on the target, thereby protecting the safety of the protected object. The working principle of the laser protection system is mainly to irradiate the target by high-energy laser beam, and to form ablation by the continuous irradiation of high-energy laser beam, so as to realize the attack effect by damaging the target structure or interfering with its electronic system. In the laser protection system, the laser beam is used to form a dynamic defense barrier, and when the incoming threat is detected, the laser beam will quickly adjust the direction and power to intercept or destroy the target.

[0004] At present, the conventional laser shield technology is weakened or cannot work normally in complex weather environments such as heavy fog, heavy snow, heavy rain and sandstorm, and the core reason is that fog droplets, snowflakes, raindrops and sand dust have strong scattering and absorption effect on laser, which limits the application scene of the laser shield technology to some extent. Therefore, improving the protection effect of the laser protection system in complex weather environment is one of the important research contents of improving the defense capability of the laser protection system.

[0005] Correspondingly, since the infrared waveband laser has strong penetration in complex weather conditions, it can improve the protection effect of the laser shield in complex weather environments such as heavy fog, heavy snow, heavy rain and sandstorm. This strong environmental adaptability makes it achieve attack effect in various complex environments, so the infrared waveband laser is widely used in the present laser protection system.

[0006] However, the laser commonly used in the industry at present is usually a single-wavelength fiber laser, which has low working condition adaptability. In the environment of heavy fog, heavy snow, heavy rain and sandstorm, there is strong light scattering and absorption effect, which leads to rapid decay of the energy density of the laser, reduces the working performance of the laser protection system in complex weather environment, and adversely affects the overall protection capability of the laser protection system.

[0007] Therefore, how to optimize the working condition adaptability of the laser protection system and improve its working performance in complex weather environment to ensure that the protection capability of the laser protection system is always stable and reliable in different working condition environments is an important technical problem to be solved by the person skilled in the art at present.

[0040] In order for those skilled in the art to better understand the utility model scheme, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0041] It needs to be explained in advance that, in the utility model, unless there are explicit provisions and limitations, the terms "installation", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, can be detachably connected, or integrally connected, can be directly connected, can be indirectly connected through an intermediate medium, and can be connected inside two elements.

[0044] Please refer to Figures 1 to 5 .

[0045] In the specific embodiment, the all-weather laser protection system provided by the utility model, including rack, the rack is provided with first infrared laser 11 and second infrared laser 12, the center wavelength of first infrared laser 11 is less than the center wavelength of second infrared laser 12.

[0046] The rack is also provided with a control assembly corresponding to each first infrared laser 11 and each second infrared laser 12, and the control assembly includes a start-stop control device 13, a cooling device 131 and a motion device 132.

[0047] In addition, the all-weather laser protection system further includes a controller in communication connection with the control assembly.

[0048] In the specific device operation process, under the conventional working condition environment, each first infrared laser 11 can be started only, so as to ensure the protection performance of the all-weather laser protection system in good weather conditions by using the stable operation of the first infrared laser 11.

[0049] When the all-weather laser protection system is in a complex weather environment such as heavy fog, heavy snow, heavy rain, sandstorm, etc., each second infrared laser 12 can be turned on. Since the central wavelength of the infrared laser emitted by the second infrared laser 12 is longer, it can better form diffraction, so as to penetrate various obstacles such as fog droplets, snowflakes, raindrops and sand, and complete reliable light path propagation. Therefore, compared with the central wavelength of the infrared laser emitted by the first infrared laser 11, the actual penetration of the infrared laser emitted by the second infrared laser 12 in the complex weather environment is stronger, and the propagation ability is better, thereby reducing the energy density decay of the infrared laser emitted by the second infrared laser 12 in the complex weather environment, and thus better overcoming the scattering and absorption of fog droplets, snowflakes, raindrops and sand, and reducing the loss of protection ability of the all-weather laser protection system in the complex weather environment.

[0050] Thus, the all-weather laser protection system can still maintain stable and reliable laser protection performance when it is in a complex weather environment such as heavy fog, heavy snow, heavy rain, sandstorm, etc., thereby greatly improving the adaptability of the all-weather laser protection system in the complex weather environment, and enabling it to maintain stable operation and reliable protection in various working conditions.

[0051] Generally, the wavelength of the first infrared laser 11 and the wavelength of the second infrared laser 12 are not less than 780 nm and not greater than 2000 nm, and the output optical power difference between the first infrared laser 11 and the second infrared laser 12 is not less than 1 W. In this way, it is ensured that the infrared laser emitted by the first infrared laser 11 and the second infrared laser 12 is near-infrared laser. On this basis, in combination with the setting that the wavelength of the infrared laser emitted by the second infrared laser 12 is greater than the wavelength of the infrared laser emitted by the first infrared laser 11, the infrared laser emitted by the second infrared laser 12 can better form diffraction in a complex weather environment such as heavy fog, heavy snow, heavy rain, sandstorm, etc., so that the long-wave infrared laser emitted by the second infrared laser 12 can penetrate obstacles such as fog droplets, snowflakes, raindrops and sand, ensuring smooth and efficient propagation of the infrared laser emitted by the second infrared laser 12, thereby making the laser protection effect of the all-weather laser protection system in the complex weather environment more reliable and effective.

[0052] It is not difficult to see that the different wavelengths of the infrared laser used in the scheme correspond to different penetration of complex weather, which is actually because the infrared laser with larger wavelength can better form diffraction to penetrate the obstacles, so that the long-wave infrared laser can continue to propagate, so that the propagation ability of the infrared laser with longer wavelength is stronger than that of the infrared laser with shorter wavelength in complex environment. This characteristic is different from the principle that the longer the wavelength, the smaller the frequency, and the worse the penetration when the conventional visible light propagates. Of course, the technical principle here can be completely understood by the workers in the field, and will not be described here.

[0053] It should be noted that in actual application, the center wavelength of the infrared laser emitted by the first infrared laser 11 is generally 850nm, 905nm, 950nm, 1064nm or 1080nm, and the energy value of the infrared laser of each wavelength is 1.46eV, 1.37eV, 1.31eV, 1.17eV and 1.15eV respectively. The center wavelength of the infrared laser emitted by the second infrared laser 12 is generally 1310nm, 1400nm or 1550nm, and the energy value of the infrared laser of each wavelength is 0.95eV, 0.89eV and 0.8eV respectively.

[0054] It is not difficult to understand that in actual operation application, each first infrared laser 11 and each second infrared laser 12 are arranged in a direction perpendicular to the ground, that is, the infrared laser emitted by each infrared laser is emitted from bottom to top along a direction perpendicular to the ground. Correspondingly, the rack can be a conventional equipment mounting bracket, or a platform type support mechanism or a plate shaped support arranged directly on the ground. In principle, as long as it can provide sufficient installation space and reliable structural support for each infrared laser.

[0055] Further, the controller can be selected from a single-chip microcomputer or a PLC (programmable logic controller) device, and the corresponding start-stop control device 13 can be selected from an electrical switch or an inductive switch module that can communicate with the corresponding type of controller. As for the cooling device 131, it can be directly matched with the cooling device 131 commonly used in the art which can be adapted to various types of infrared lasers, and will not be described here.

[0056] Correspondingly, the motion device 132 generally includes a translation mechanism capable of driving each infrared laser to reciprocate along the horizontal direction and a lifting mechanism capable of driving each infrared laser to reciprocate along the vertical direction. The translation mechanism and the lifting mechanism can be respectively realized by slide rail mechanism, screw mechanism and other action mechanisms, or can be respectively realized by air cylinder, oil cylinder or electric cylinder and other linear driving mechanisms. The corresponding device arrangement and mechanism adaptation installation can be directly applied by referring to the conventional technology, and will not be described here.

[0057] On this basis, the motion device 132 further comprises an angle adjusting mechanism capable of reciprocating the first infrared laser 11 or the second infrared laser 12 to adjust the laser emission angle. In actual application, the controller can be used to control the action of the angle adjusting mechanism to achieve moderate swinging of each infrared laser, so as to adjust the laser emission direction of each infrared laser to meet the current defense direction, so as to meet the current defense requirement. Considering the application requirement in most working conditions, the angle adjustment range of the laser emission direction of each infrared laser under the driving of the angle adjusting mechanism is 45°.

[0058] Generally, the angle adjusting mechanism can be realized by a swing rod mechanism, or a hinge mechanism formed by matching each infrared laser with corresponding assembly, and then combined with a driving device such as a cylinder to drive the corresponding infrared laser to reciprocate around the hinge shaft. In fact, the specific application type of the angle adjusting mechanism of each infrared laser is not limited to this, and in actual application, the staff can flexibly select the implementation mode of the angle adjustment of the infrared laser according to the actual working condition requirement. In principle, as long as it can meet the actual application needs of the all-weather laser protection system, it is acceptable.

[0059] Specifically, the rack is provided with a plurality of first mounting surfaces 141 and a plurality of second mounting surfaces 142, and the first mounting surfaces 141 are arranged adjacent to the second mounting surfaces 142. At least one first infrared laser 11 is arranged in each first mounting surface 141, and no second infrared laser 12 is arranged in the first mounting surface 141. At least one second infrared laser 12 is arranged in each second mounting surface 142, and no first infrared laser 11 is arranged in the second mounting surface 142. The first mounting surface 141 can provide sufficient and reliable assembly space for each first infrared laser 11, and the second mounting surface 142 can provide sufficient and reliable assembly space for each second infrared laser 12.

[0060] On this basis, by flexibly adjusting and combining the arrangement positions of each first mounting surface 141 and each second mounting surface 142, a matching laser assembly layout can be obtained according to different working condition environments and protection application requirements, so that the adaptability of the all-weather laser protection system to different working condition environments is further improved. Moreover, arranging each first infrared laser 11 and each second infrared laser 12 on each first mounting surface 141 and each second mounting surface 142 respectively can appropriately avoid structural interference or optical path interference between each first infrared laser 11 and each second infrared laser 12, so as to further ensure that each first infrared laser 11 and each second infrared laser 12 can stably operate, and thus the overall working reliability of the all-weather laser protection system is correspondingly improved.

[0061] Please refer to Figure 3 andFigure 4 The first mounting surfaces 141 and the second mounting surfaces 142 are alternately arranged and connected end to end in the circumferential direction of the frame to form the hybrid protection area 15. For the convenience of understanding, the infrared laser emitted by the first infrared laser 11 is denoted as λ1, and the infrared laser emitted by the second infrared laser 12 is denoted as λ2. The specific denotation of the infrared laser emitted by the first infrared laser 11 and the second infrared laser 12 in the remaining part of the text can be understood according to the illustration.

[0062] The structure and layout of the hybrid protection area 15 can enable the first mounting surfaces 141 on which the first infrared laser 11 is mounted to be alternately arranged with the second mounting surfaces 142 on which the second infrared laser 12 is mounted, so that the first infrared laser 11 and the second infrared laser 12 can be uniformly arranged. In this way, the all-weather laser protection system can not only ensure the laser protection performance in good weather environments under general working conditions, but also ensure the laser protection performance in complex weather environments. Therefore, the working condition adaptability of the all-weather laser protection system is further improved, and the laser protection performance in different weather environments remains reliable and efficient.

[0063] Correspondingly, the shape of the hybrid protection area 15 can be a square arrangement structure as shown in the figure, or a circular, elliptical, triangular, or polygonal structure. In actual installation and arrangement, the ring layout as shown in Figure 3 or a densely arranged array arrangement structure can be used. In actual application, the worker can flexibly select and adjust according to the specific working condition requirements.

[0064] On the other hand, please refer to Figure 5 The second mounting surfaces 142 are alternately arranged and connected end to end in the circumferential direction of the frame to form the second protection area 162, and the first mounting surfaces 141 are alternately arranged and connected end to end in the circumferential direction of the frame to form the first protection area 161 located in the second protection area 162. The arrangement of the first protection area 161 and the second protection area 162 requires more second infrared lasers 12, so that the arrangement is better for laser protection in complex weather environments such as heavy fog, heavy snow, heavy rain, and sandstorm, and can fully ensure the laser energy density of the all-weather laser protection system in complex weather environments and ensure its protection performance.

[0065] More specifically, the second protection area 162 is annular, and the outer edge of the first protection area 161 coincides with the inner edge of the second protection area 162. The coinciding structure here refers to the outer edge of the first protection area 161 being adjacent to and connected with the inner edge of the second protection area 162, so as to ensure the compact arrangement of the first protection area 161 and the second protection area 162. Of course, in actual installation arrangement, any first infrared laser 11 in the first protection area 161 and any second infrared laser 12 in the second protection area 162 can be arranged in contact or with a gap, without particular limitation on the specific matching arrangement.

[0066] Generally, the first protection area 161 is in any one of a circular shape, an elliptical shape, a triangular shape, a square shape or a polygonal shape, and the second protection area 162 is also in any one of a circular shape, an elliptical shape, a triangular shape, a square shape or a polygonal shape. It is not difficult to understand that, in actual application, the first protection area 161 can adopt a square annular structure as shown in the figure, or a square array arrangement structure, or other annular arrangement or array arrangement structures. Regardless of the shape of the second protection area 162, it should be arranged in an annular structure, so as to arrange the first protection area 161 completely inside the second protection area 162, and thus ensure the cooperative effect of the first infrared laser 11 and the second infrared laser 12.

[0067] It should be particularly pointed out that, for good weather environment in general working conditions, each first infrared laser 11 can be turned on and kept normal operation, or each first infrared laser 11 and each second infrared laser 12 can be turned on and kept normal operation at the same time, so as to further optimize and supplement the protection effect of the second infrared laser 12 on the all-weather laser protection system in good weather environment. Of course, considering the overall operation cost and energy consumption of the equipment, it is appropriate to turn on only each first infrared laser 11 and turn off each second infrared laser 12 in good weather.

[0068] In addition, considering the operation mode of each infrared laser, the first infrared laser 11 can be a continuous wave laser or a pulse wave laser, and the second infrared laser 12 can also be a continuous wave laser or a pulse wave laser. Considering the specific type of laser, the first infrared laser 11 and the second infrared laser 12 can be selected from a ruby laser, a neodymium yttrium aluminum garnet (YAG) laser, a vertical cavity surface emitting laser (VCSEL), a fiber laser, a solid-state laser or other types of lasers. In principle, as long as it can meet the actual application needs of the all-weather laser protection system.

[0069] In summary, it can be seen that during the operation of the all-weather laser protection system provided by the present invention, under normal working conditions, only the first infrared lasers can be turned on, so as to utilize the stable operation of the first infrared lasers to ensure the protection performance of the all-weather laser protection system under good weather conditions; when the all-weather laser protection system is in complex weather environments such as heavy fog, heavy snow, heavy rain, sandstorms, etc., the second infrared lasers can be turned on. Since the infrared lasers with longer central wavelengths emitted by the second infrared lasers can better form diffraction, they can penetrate various obstacles such as fog droplets, snowflakes, raindrops and sand and dust, and complete reliable optical path propagation. Therefore, compared with the infrared lasers with shorter central wavelengths emitted by the first infrared lasers, the second infrared lasers can emit infrared lasers with longer central wavelengths. The infrared laser emitted by the second infrared laser has stronger actual penetration and better propagation ability in complex weather environments, thereby reducing the energy density attenuation of the infrared laser emitted by the second infrared laser in complex weather environments, and thus can better overcome the scattering and absorption effects of fog droplets, snowflakes, raindrops and dust, and reduce the loss of protection capability of the all-weather laser protection system in complex weather environments. This ensures that the all-weather laser protection system can still maintain stable and reliable laser protection performance in complex weather environments such as heavy fog, heavy snow, heavy rain, sandstorms, etc., thereby greatly improving the adaptability of the all-weather laser protection system in complex weather environments, and enabling it to maintain stable operation and reliable protection in all types of working environments.

This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
