Description

Technical Field

[0001] This invention relates to the field of patrol camouflage technology, specifically a dynamic cloak camouflage control system for patrol unmanned vehicles. Background Technology

[0002] To improve the safety of camp patrols and reduce the labor intensity of patrol personnel, using patrol robots to patrol around the camp can significantly improve personnel safety and reduce labor intensity. To increase the stealth of patrol robots, they are often covered with a camouflage layer. The camouflage layer is mainly related to the environment, such as grassland, snow, desert, etc., which can increase stealth and detect potential threats.

[0003] However, when the patrol area is large, the environment along the patrol route will change, such as concrete roads, grassy areas, areas full of yellow sand, shrubbery, etc. In this case, the single coverage of the patrol robot may turn from an advantage to a disadvantage. For example, the basic color of the yellow sandy area is yellow, and the basic color of the grassy area is green. In this case, the yellow camouflage layer will become more obvious when entering the grassy area, thus turning the advantage into a disadvantage. Summary of the Invention

[0004] The purpose of this invention is to provide a dynamic cloak camouflage control system for patrol unmanned vehicles, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dynamic cloak camouflage control system for patrol unmanned vehicles includes a main compartment rotatably connected above a drive unit and a collection compartment fixedly connected above the main compartment. The outer wall of the main compartment has an arc-shaped sliding portion and an inwardly folding portion from top to bottom.

[0007] The top of the main compartment is provided with multiple dynamic camouflage modules from the inside to the outside. The dynamic camouflage modules are located on the outside of the collection compartment. Each dynamic camouflage module includes a main camouflage layer covering the outside of the main compartment and a collection camouflage layer covering the outside of the collection compartment. The main camouflage layer and the collection camouflage layer are housed inside the main compartment.

[0008] The bottom surface of the main camouflage layer is fixedly connected with several ring-shaped covering combination rods. Each covering combination rod is composed of several rhomboid connecting units that are hinged to each other. Two adjacent rhomboid connecting units are hinged together by a hinge shaft. A torsion spring is provided inside the hinge shaft. When the torsion spring is static, the rhomboid connecting unit bends outward, and the covering combination rod contacts the arc-shaped sliding part. The end of the covering combination rod covers the outside of the inner buckling part. The main camouflage layer is affected by the covering combination rod and bends towards the inner buckling part to cover it.

[0009] An inner covering rod is fixedly connected to the bottom surface of the collection camouflage layer. When the main camouflage layer covers the main compartment, the inner covering rod bends inward, so that the collection camouflage layer covers the outside of the collection compartment to achieve wrapping.

[0010] As a further embodiment of the present invention: the top of the collection chamber is an open structure, and a top cover is fixedly connected to the top of the collection chamber, with a gap between the top cover and the collection chamber for sound to pass through.

[0011] As a further aspect of the present invention: the acquisition chamber contains an acquisition lens and a sound acquisition module. The sound acquisition module controls the rotation angle of the acquisition chamber through time delay positioning to adjust the acquisition direction of the acquisition lens. The drive unit is equipped with a speed adjustment mechanism to adjust the forward speed of the drive unit according to the sound acquired by the sound acquisition module.

[0012] As a further embodiment of the present invention: the top of the main body is provided with several storage compartments that cooperate with the dynamic camouflage module. A connecting ring is slidably connected in the storage compartment. The main camouflage layer, the collection camouflage layer, and the covering combination rod are all stored inside the storage compartment. The movement of the connecting ring is controlled by the instantaneous release winding module.

[0013] As a further embodiment of the present invention: a traction spring is installed inside the storage compartment to pull the open window upward; the instant-release winding module includes a winding roller, a toothed groove, a drive shaft, a locking pin, and a magnetic attraction unit; a traction rope is wound around the outside of the winding roller, one end of which is fixedly connected to the bottom surface of the connecting ring; the drive shaft is rotatably connected to the inner hole of the winding roller by a motor; the toothed groove is formed on the inner wall of the winding roller; a locking pin that mates with the toothed groove is slidably connected to the circumference of the drive shaft; and the locking pin is driven to extend and retract by the magnetic attraction unit.

[0014] As a further embodiment of the present invention: the rhomboid connecting unit is fixedly connected to a limiting block on the side near the main camouflage layer, the main camouflage layer is fixedly connected to the inner side of the rhomboid connecting unit, the collection camouflage layer is fixedly connected to the outer side of the inner covering rod, and the collection camouflage layer is located inside the covering combination rod.

[0015] As a further embodiment of the present invention: several groups of the covering combination rods are staggered, the inner covering rod is hinged to the acquisition camouflage layer, the distribution direction of the several groups of the inner covering rods is consistent, and the acquisition camouflage layer is provided with an open window that cooperates with the acquisition lens.

[0016] As a further embodiment of the present invention: a magnetic suction part is fixedly connected to the bottom of the inwardly folding part, and a magnetic block that is magnetically connected to the magnetic suction part is fixedly connected to the bottom of the main body camouflage layer.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Multiple dynamic camouflage modules are set up, and these modules can be switched and collapsed. The dynamic camouflage modules achieve complete coverage by combining the outer enclosure of the main camouflage layer with the inner enclosure of the acquisition camouflage layer. At the same time, the acquisition camouflage layer and the main camouflage layer can be closed and surrounded by unused dynamic camouflage modules, which increases the concealment effect. Multiple dynamic camouflage modules can be selected and replaced according to location information and environmental conditions.

[0019] The compartmentalized design places the collection compartment at the top to avoid camouflage interfering with the collection. The main compartment has an arc-shaped sliding section and an inward-curving section to reduce wind resistance. Combined with the covering combination rod, the main camouflage layer is attached to the arc-shaped sliding section and the inward-curving section. At this time, the main camouflage layer forms a bending surface on the main compartment. When the main compartment is affected by wind, the main camouflage layer will not separate from the main compartment, avoiding the failure of concealment and the situation where the concealment layer hinders the collection.

[0020] Due to the diamond-shaped connection unit, when the dynamic camouflage module switches, the contact surface between the main camouflage layer and the diamond-shaped connection unit of another dynamic camouflage module is converted into a point, reducing the contact area and making the sliding of the main camouflage layer smoother, and making the inner and outer coverage switching of the dynamic camouflage module smoother.

[0030] Please see Figures 1-7

[0031] It includes a main chamber 1 rotatably connected to the drive unit and a collection chamber 2 fixedly connected to the main chamber 1. The outer wall of the main chamber 1 has an arc-shaped sliding part 11 and an inwardly folding part 12 from top to bottom.

[0032] The drive unit is implemented through a decision system combined with the LivoxAVIA solid-state lidar, which is unaffected by day or night light. After the unmanned patrol vehicle enters the patrol area, it first uses the lidar to scan the environment and uses an octree algorithm to create a 3D point cloud map of the area to be patrolled, which is then converted into a 2D map. Next, it uses the amcl-3d positioning algorithm to determine its own position. Then, it uses the DIJKSTRA'S algorithm to plan obstacles in the designated area and uses the dynamic window method to search for multiple paths for avoidance and travel. The optimal path is selected by combining various evaluation criteria (whether it will collide with obstacles, the time required, etc.). During the movement, the dynamic window method (DWA) is used to perform local obstacle avoidance in a timely manner. Finally, it completes the autonomous navigation of the designated area. Since the environment around the camp is relatively fixed, it can select the corresponding camouflage layer to switch camouflage according to its own position, thereby improving its concealment.

[0033] At this point, a main compartment 1 and a data acquisition compartment 2 are set up. The main compartment 1 is mainly used to store the power supply mechanism, processor, etc., while the data acquisition compartment 2 is mainly used to house the data acquisition components, such as sound, images, and radar obstacle detection. The purpose of the dual-compartment design is to achieve complete enclosure of the necessary structures, such as power supply and computing devices. These necessary structures mainly provide power and computing for the data acquisition mechanism, so complete enclosure will not affect the use. The core structure is stored inside the data acquisition compartment 2. Since the data acquisition compartment 2 requires special treatment and a data acquisition window is reserved in advance, and the core structure is relatively small, it is placed on top of the data acquisition compartment 2 using a special covering method to improve concealment while meeting the usage requirements.

[0034] The main body 1 has an arc-shaped sliding part 11 and an inward-curving gathering part 12. The purpose of setting the arc-shaped sliding part 11 is mainly to allow the camouflage cloth to move downward along the arc surface of the arc-shaped sliding part 11 under the influence of gravity. However, due to the presence of the drive wheel, the inward-curving gathering part 12 is set so that the camouflage cloth will bend to the inward-curving gathering part 12 after moving downward under the influence of gravity. After bending, the camouflage cloth forms a cover. The advantage of the cover is that the camouflage cloth will not lift up and block the lens when encountering strong winds, and at the same time, the hem of the camouflage cloth will not swing, avoiding getting caught in the wheel and causing wheel damage.

[0035] Multiple dynamic camouflage modules 100 are arranged from the inside to the outside on the top of the main chamber 1. The dynamic camouflage modules 100 are located on the outside of the collection chamber 2. The dynamic camouflage modules 100 include a main camouflage layer 3 covering the outside of the main chamber 1 and a collection camouflage layer 4 covering the outside of the collection chamber 2. The main camouflage layer 3 and the collection camouflage layer 4 are housed inside the main chamber 1. Several annularly distributed covering combination rods 5 are fixedly connected to the bottom surface of the main camouflage layer 3. The covering combination rods 5 are composed of several rhomboid connecting units 51 that are hinged to each other. There is a connection between two adjacent rhomboid connecting units 51. The hinge is connected via hinge shaft 52, and a torsion spring 53 is provided inside the hinge shaft 52. When the torsion spring 53 is static, the diamond-shaped connecting unit 51 bends outward, and the covering combination rod 5 contacts the arc-shaped sliding part 11. The end of the covering combination rod 5 covers the outside of the inner buckling part 12. The main body camouflage layer 3 is affected by the covering combination rod 5 and bends inward to cover the inner buckling part 12. The bottom surface of the collection camouflage layer 4 is fixedly connected to the inner covering rod 42. When the main body camouflage layer 3 covers the main chamber 1, the inner covering rod 42 bends inward, so that the collection camouflage layer 4 covers the outside of the collection chamber 2 to achieve wrapping.

[0036] Firstly, through Figure 1 As can be seen, the storage compartment 13 surrounds the periphery of the collection compartment 2. The storage compartment 13 stores the main camouflage layer 3 and the collection camouflage layer 4. At this time, the storage compartment 13 is a series of concentric annular grooves with different diameters. After the covering combination rod 5 is inserted into the storage compartment 13, the covering combination rod 5 is forced to be in a vertical state due to the influence of the groove width of the storage compartment 13. However, when camouflaging, the covering combination rod 5 is pushed out from the inside of the storage compartment 13. At this time, the main camouflage layer 3 covers the inner side of the covering combination rod 5. When the first section of the diamond connecting unit 51 is pushed out from the storage compartment 13, the torsion spring 53 inside the hinge shaft 52 is not affected by the limit, which drives the first end of the diamond connecting unit 51 to bend outward and fit against the top of the arc-shaped sliding part 11. As the diamond connecting unit 51 continues to rise, a large number of diamond connecting units 51 are continuously bent and covered by the torsion spring 53. The main camouflage layer 3 slides downwards against the arc-shaped sliding part 11. When it slides to the inner closing part 12, the diamond-shaped connecting unit 51 is no longer affected by the arc-shaped sliding part 11, and the torsion spring 53 continues to bend. This causes the covering combination rod 5 to drive the main camouflage layer 3 to bend towards the inner closing part 12. Since the inner closing part 12 is distorted inwards, the main camouflage layer 3 forms an inward bend at the inner closing part 12. When affected by wind, the wind will act on the arc-shaped sliding part 11 and the inner closing part 12. Since the inner closing part 12 is a ring, the horizontal wind will be decomposed at the arc-shaped sliding part 11 and the inner closing part 12, so that the main camouflage layer 3 and the main compartment 1 are in a tight fit. This prevents the entire camouflage from being affected by the wind and causing camouflage failure or camouflage to block the collection equipment. Since the main compartment 1 is equipped with necessary structures, it can be completely shielded.

[0037] As the covering combination rod 5 continues to rise, the inner covering rod 42 is also exposed from the storage compartment 13. The inner covering rod 42 is connected to the connecting ring 31 through an elastic hinge or other flexible rotating connection structure. When the connecting ring 31 moves above the storage compartment 13, the inner wall of the storage compartment 13 can no longer limit the inner covering rod 42. At this time, the inner covering rod 42 will be affected by the elastic structure inside the rotating structure and rotate inward, so that the inner covering rod 42 covers the surface of the collection compartment 2. At this time, the collection camouflage layer 4 is fixed by the inner covering rod 42, so that the collection camouflage layer 4 is attached to the periphery of the collection compartment 2, thereby achieving complete coverage.

[0038] The top of the acquisition chamber 2 is an open structure, and a top cover 23 is fixedly connected to the top of the acquisition chamber 2. There is a gap between the top cover 23 and the acquisition chamber 2 to allow sound to pass through. Since the acquisition chamber 2 is equipped with a sound acquisition module 22, which consists of multiple ring-shaped acquisition microphones, the sound transmitted from the outside will take different times to acquire the sound due to the distance, which is called time delay. Based on the time delay, the direction of the sound-emitting area can be located, thereby controlling the movement of the acquisition chamber 2 as a whole on the drive unit, thereby adjusting the image acquisition direction. The reason for setting the gap is mainly to reduce the penetration loss of sound energy, making it easier for sound to enter the interior of the acquisition chamber 2 and be acquired by the sound acquisition module 22. The top cover 23 can block the top of the acquisition chamber 2 while ensuring that the sound passes through, preventing rainwater from dripping onto the sound acquisition module 22 and affecting it.

[0039] The acquisition chamber 2 contains an acquisition lens 21 and a sound acquisition module 22. The sound acquisition module 22 controls the rotation angle of the acquisition chamber 2 through time delay positioning and adjusts the acquisition direction of the acquisition lens 21. The drive unit is equipped with a speed adjustment mechanism to adjust the forward speed of the drive unit according to the sound acquired by the sound acquisition module 22.

[0040] First, after the sound acquisition module 22 locates the source based on the time delay, the acquisition lens 21 rotates to the sound source area. The danger is judged based on the type of sound source and the image. The sound source type includes frequency and decibels, while the image can show the state of the area. Various types of audio segments such as gunshots, explosions, and human speech are acquired to obtain frequency and decibel characteristics. In practical applications, after the sound frequency and decibel characteristics acquired by the sound acquisition module 22 are combined with the time delay location, the image of the sound source area is acquired through the acquisition lens 21. The sound characteristics are then compared with the image to confirm the sound source type. The forward speed of the drive unit is then adjusted to achieve slow, low-noise or fast forward movement.

[0041] The top of the main body 1 has several storage compartments 13 that cooperate with the dynamic camouflage module 100. A connecting ring 31 is slidably connected inside the storage compartment 13. The main camouflage layer 3, the collection camouflage layer 4, and the covering combination rod 5 are all stored inside the storage compartment 13. The movement of the connecting ring 31 is controlled by the instant release and rewinding module 6.

[0042] To ensure the fit between the main camouflage layer 3 and the arc-shaped sliding part 11, a wrapping combination rod 5 is used. Since the rhomboid connecting units 51 are hinged to each other, they will bend outwards when not subjected to external force. At this time, the storage compartment 13 can limit the rhomboid connecting units 51, so that the rhomboid connecting units 51 are stored in the storage compartment 13 approximately vertically. At the same time, the main camouflage layer 3 is also hidden inside the storage compartment 13. In order to make the entire main camouflage layer 3 integrated, a connecting ring 31 is set. The instant release winding module 6 only needs to control the independent lifting and lowering of the connecting ring 31 to release multiple wrapping combination rods 5 to the outside. When the wrapping combination rods 5 bend outwards, they form a flower-like shape covering the surface of the arc-shaped sliding part 11. The purpose of setting the instant release winding module 6 is to achieve the rapid laying of the main camouflage layer 3.

[0043] The storage compartment 13 is equipped with a traction spring 15 that pulls the connecting ring 31 upward. The instant release winding module 6 includes a winding roller 61, a toothed groove 62, a drive shaft 63, a locking post 64, and a magnetic attraction unit 65. A traction rope is wound around the outside of the winding roller 61. One end of the traction rope is fixedly connected to the bottom surface of the connecting ring 31. The drive shaft 63 is rotatably connected to the inner hole of the winding roller 61 by a motor. The toothed groove 62 is opened on the inner wall of the winding roller 61. A locking post 64 that cooperates with the toothed groove 62 is slidably connected to the periphery of the drive shaft 63. The locking post 64 is driven to extend and retract by the magnetic attraction unit 65.

[0044] The traction spring 15 can also be an elastic rope. When the connecting ring 31 is pulled into the storage compartment 13 at the bottom by the traction of the traction rope, the traction spring 15 is in a state of elastic tension. When it is released quickly, the locking pin 64 is put into the side of the drive shaft 63 by the magnetic attraction of the magnetic attraction unit 65. At this time, the locking pin 64 cannot limit the tooth groove 62, and the winding roller 61 moves relative to the drive shaft 63 quickly. At this time, the traction spring 15 resets and quickly pulls the connecting ring 31 upward. The covering combination rod 5 is quickly spread outward and laid. The covering combination rod 5 slides down along the arc-shaped sliding part 11 under the influence of gravity and then folds into the inside of the inner buckling and gathering part 12.

[0045] A limiting block 511 is fixedly connected to the side of the rhomboid connecting unit 51 near the main camouflage layer 3. The main camouflage layer 3 is fixedly connected to the inner side of the rhomboid connecting unit 51. The collection camouflage layer 4 is fixedly connected to the outer side of the inner covering rod 42. The collection camouflage layer 4 is located inside the covering combination rod 5.

[0046] Since the rhomboid connecting unit 51 can only rotate in one direction, a limiting block 511 is set to prevent the bending direction from changing, so that the rhomboid connecting unit 51 can only rotate outward. At the same time, the main body camouflage layer 3 is inside the rhomboid connecting unit 51, and the acquisition camouflage layer 4 is outside the inner covering rod 42. The main body camouflage layer 3 and the acquisition camouflage layer 4 are a group. At this time, the camouflage cloth of the main body camouflage layer 3 and the acquisition camouflage layer 4 is the same. Therefore, the main body camouflage layer 3 and the acquisition camouflage layer 4 can be connected by the connecting layer. When the main body camouflage layer 3 and the acquisition camouflage layer 4 are unfolded, a smooth image transition can be achieved between the two, increasing the concealment effect.

[0047] Several sets of wrapping rods 5 are staggered, the inner wrapping rods 42 are hinged to the collection camouflage layer 4, the distribution direction of the several sets of inner wrapping rods 42 is consistent, and the collection camouflage layer 4 has an open window 41 that cooperates with the collection lens 21.

[0048] Since the trolley needs to perform two actions, storing camouflage and laying camouflage, when switching camouflage according to its own position and the current environment, although the covering combination rod 5 is tightly attached to the arc-shaped sliding part 11 and the inner buckling part 12, the main body camouflage layer 3 between two adjacent covering combination rods 5 is not tightly attached, thus there is a gap. At this time, it is divided into inner coverage and outer coverage. Meanwhile, the open window 41 is mainly to maximize the reduction of the exposed area and avoid the acquisition lens 21 from being blocked.

[0049] outer coverage

[0050] See Figure 3 The outer main camouflage layer 3 and the collection camouflage layer 4 cover the arc-shaped sliding part 11, the inner buckling part 12 and the collection chamber 2. At this time, the collection camouflage layer 4 hinders the laying of the inner camouflage cloth. Therefore, when the inner dynamic camouflage module 100 switches with the outer dynamic camouflage module 100.

[0051] First, the outer connecting ring 31 is driven to roll downwards. At this time, the camouflage layer 4 enters the storage compartment 13. The inner covering rod 42 is opened by the storage compartment 13. At this time, the end passage of the inner storage compartment 13 is opened until the inner covering rod 42 is completely retracted into the storage compartment 13. Then, the instant release winding module 6 is activated to quickly release the inner storage compartment 13. After the quick release, the covering combination rod 5 quickly pushes out from the top of the storage compartment 13, and the diamond connecting unit 51 quickly bends to cover the arc-shaped sliding part 11 and the inner buckling part 12. At this time, the outer main camouflage layer 3 has been covered by the inner main camouflage layer 3. Then, the instant release winding module 6 continues to roll the covered main camouflage layer 3. The covering combination rods 5 of the two main camouflage layers 3 are staggered. Therefore, the covering combination rods 5 of the two sets of dynamic camouflage modules 100 will not interfere with each other, thereby realizing the switching of camouflage cloth.

[0052] Inner Coverage

[0053] The inner cover is the opposite of the above. At this time, the main camouflage layer 3 blocks the outer storage compartment 13. In this stage, the main camouflage layer 3 inside the outer storage compartment 13 is laid in advance. Before reaching the designated environmental area, the instantaneous release winding module 6 is released. After release, the connecting ring 31 moves upward, and the covering combination rod 5 is pushed upward and then quickly bends. At this time, the covering combination rod 5 and the main camouflage layer 3 have been covered on the arc-shaped sliding part 11 and the inner buckling gathering part 12. The subsequent covering combination rod 5 passes through the surface of the arc-shaped sliding part 11. The two covering combination rods 5 pass between each other, while the subsequent main camouflage layer 3 passes under the already covered covering combination rods 5 on the arc-shaped sliding part 11. After the camouflage cloth is laid, the outer main camouflage layer 3 is rolled up, thus realizing the switching after the inner cover is laid in advance. After the edge of the rhomboid connecting unit 51 is set with an arc corner, when the main camouflage layer 3 passes through the rhomboid connecting unit 51, it is affected by the resistance of the rhomboid connecting unit 51 and changes from a surface to a point, thereby improving the smoothness of the sliding of the main camouflage layer 3.

[0054] A magnetic suction part 14 is fixedly connected to the bottom of the inwardly folding part 12, and a magnetic block that is magnetically connected to the magnetic suction part 14 is fixedly connected to the bottom of the main camouflage layer 3. The main camouflage layer 3 is bent downward at the bottom due to the influence of the covering combination rod 5. At this time, the magnetic block will contact the magnetic suction part 14, so that the main camouflage layer 3 can be fixed more stably. The magnetic suction part 14 can be made of metal sheet. Since there may be a double camouflage cloth when switching camouflage cloth, the metal sheet can increase the adsorption area and allow the bottom magnetic blocks of both main camouflage layers 3 to be adsorbed by the magnetic suction part 14.

[0055] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
