Description

Technical Field

[0001] The present invention relates to a self-stabilizing detection device based on multi-source coordination and dynamic aerodynamic compensation, belonging to the technical field of intelligent monitoring equipment. Background Art

[0002] The field of ocean monitoring places stringent demands on the ability to operate continuously in extreme environments: marine law enforcement agencies must achieve continuous monitoring of designated sea areas, and there is an urgent need to deploy meteorological monitoring equipment in typhoon eye zones. Existing technology systems have the following limitations: Traditional rigid mechanically coupled turntable systems have structural flaws. Their fixed dock installation method results in a fixed monitoring area and makes deep-sea deployment difficult. In moderate sea conditions and above, the onboard mounting system causes dynamic load compensation failure, resulting in a significant degradation of the imaging system's spatial resolution and reduced stability of inertial sensor elements. Limited by the physical constraints of the optical component's field of view, the probability of target capture is significantly reduced. There are also devices for monitoring through drones in the existing technology. However, first, marine meteorological conditions are complex and changeable. Severe weather such as strong winds, heavy rains, and heavy fog will seriously affect the flight safety and monitoring effect of drones. In particular, drones have weak wind resistance. Strong winds may cause drones to deviate from the planned route or even fail to fly normally; second, the size and load capacity of drones are relatively limited, making it difficult to carry a variety of complex and high-precision sensors, resulting in certain limitations on the type and accuracy of environmental data they obtain; third, the coverage range of drones is small. For large areas of sea, if you want to achieve large-scale monitoring, multiple drones need to operate simultaneously or one drone needs to make multiple round trips, which affects monitoring efficiency and leads to higher monitoring costs; fourth, the battery life of drones is limited. Once the battery is low, the drone may fall, causing equipment damage or even causing a safety accident.

[0003] Therefore, there is an urgent need for a detection device with better wind resistance, larger load capacity and larger detection range for sea surface environment detection. Summary of the Invention

[0004] The present invention aims to solve the problems of poor wind resistance, small load capacity and small detection range in existing equipment for sea surface environment detection, and further provides a self-stabilizing detection device based on multi-source collaboration and dynamic aerodynamic compensation.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A self-stabilizing detection device based on multi-source coordination and dynamic aerodynamic compensation includes a rotor assembly, a drive system, a dynamic airflow control assembly and a detection assembly arranged in sequence from top to bottom, wherein the drive system provides power for the rotor assembly and the dynamic airflow control assembly, and the battery provides power for the entire detection device. The dynamic airflow control assembly includes an air cage, a fan, an air compressor, an air chamber and a plurality of air nozzles. The air cage is arranged below the drive system and has a plurality of air vents on it. The fan is located in the air cage and is driven to rotate by the drive system. The air compressor is connected and arranged below the air cage. The air chamber is arranged around the air compressor and is connected to the air outlet of the air compressor. The plurality of air nozzles are circumferentially arranged outside the air chamber. A control valve is provided between each air nozzle and the air chamber.

[0007] The detection component includes a reflection component, a detection radar and multiple first infrared cameras. The reflection component has an umbrella-shaped structure. The detection radar and multiple first infrared cameras are all located below the reflection component. The detection radar and the first infrared cameras both have angle adjustment functions. The reflection component reflects the infrared light emitted by the first infrared camera below it to expand the infrared field of view.

[0008] Furthermore, a plurality of flow guide channels are arranged inside the air chamber, and the plurality of air nozzles are correspondingly connected to the plurality of flow guide channels.

[0009] Furthermore, each air nozzle is rotationally connected to the air chamber via a first rotation adjustment mechanism.

[0010] Furthermore, the drive system includes a housing and a motor, an encoder, an inertial navigation module, a gyroscope, a motor connecting shaft and a power shaft arranged in the housing, wherein the power shaft and the motor connecting shaft are sequentially installed in the rotor of the motor from the inside to the outside, the rotor assembly is fixed to the top end of the power shaft through the rotor connecting shaft, the fan is fixed to the bottom end of the power shaft through the torque transmission shaft, and the encoder, inertial navigation module and gyroscope are all fixed in the housing through the encoder adapter plate.

[0011] Furthermore, the reflection assembly includes a mounting base, a flexible reflection body and a plurality of angle adjustment brackets, wherein the mounting base is fixedly mounted on the bottom end of the dynamic airflow control assembly, the plurality of angle adjustment brackets are arranged circumferentially along the mounting base, and one end of each angle adjustment bracket is rotationally connected to the mounting base through a second rotation adjustment mechanism, one end of the flexible reflection body is rotationally mounted on the bottom end of the dynamic airflow control assembly or the side wall of the mounting base, the lower surface of the flexible reflection body is fixedly connected to the plurality of angle adjustment brackets, and the retraction and extension control of the flexible reflection body is achieved by controlling the rotation of the plurality of angle adjustment brackets.

[0012] Furthermore, the flexible reflective body includes several supporting frames distributed radially, a flexible membrane cloth laid in an umbrella shape and fixed on the several supporting frames, and a reflective film layer coated on the lower surface of the flexible membrane cloth. One end of the several supporting frames is rotatably connected to the bottom end of the dynamic airflow control component or the side wall of the mounting base.

[0013] Furthermore, the upper surface of the flexible reflective body is paved with a solar panel, and the solar panel is connected to a storage battery.

[0014] Furthermore, the detection assembly also includes a plurality of precision tracking devices installed above the reflection assembly, and each precision tracking device includes a three-axis stable platform and a second infrared camera and a visible light camera installed on the three-axis stable platform.

[0015] Furthermore, the rotor assembly includes a rotor box and a plurality of rotors evenly distributed along the circumference of the rotor box, and a center of mass adjustment assembly is provided in the rotor box.

[0016] Furthermore, the detection radar is installed between the multiple first infrared cameras through a vertical telescopic structure.

[0017] Compared with the prior art, the present invention has the following effects:

[0018] The start and stop of the rotor assembly and the dynamic airflow control assembly are controlled by the drive system. The drive system is activated to drive the rotor assembly to rotate, so that the entire detection device takes off; the drive system drives the fan to rotate, and the fan rotation absorbs external wind or airflow, and then sucks the airflow into the air cage. By setting control valves, separate control of several air nozzles is achieved, including controlling the start and stop of the air nozzles and the gas flow of each air nozzle, further improving the suspension force of the self-stabilizing detection device. When the self-stabilizing detection device is stationary, it can effectively offset the impact of strong winds on the device, thereby making the entire detection device have better wind resistance and greatly improving the stability of the entire detection device.

[0019] The self-stabilizing detection device based on multi-source collaboration and dynamic aerodynamic compensation of the present invention utilizes aerodynamics, and several air nozzles spray air downward, which can effectively increase the load capacity of the entire detection device. Compared with the existing technology, it can carry more complex and high-precision sensors.

[0020] By setting up an umbrella-shaped reflective component, the field of view limitations of traditional optical systems can be broken through and the infrared detection field of view can be expanded.

[0021] The detection radar is installed between multiple first infrared cameras as a supplementary search method for the first infrared cameras.

[0022] The angle of each first infrared camera is adjustable, allowing the infrared light emitted by the first infrared camera to pass through or not pass through the reflective assembly. When the infrared light emitted by the first infrared camera is not reflected by the reflective assembly, it can detect and accurately track the target; when it is reflected by the reflective assembly, it can expand the infrared field of view and increase the detection range of the device.

[0023] The number of the first infrared cameras can increase the detection frequency. When multiple targets are found, some of the first infrared cameras can track them while the other first infrared cameras continue searching. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Specific implementation method 1: Combination Figures 1 to 8 This embodiment is explained, and the technical solutions in the embodiment of the present invention are clearly and completely described. Obviously, the described embodiment is only a part of the embodiment of the present invention, rather than all the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] It should be noted that the descriptions of the present invention regarding directions such as "front", "back", "left", "right", "inside", "outside", "left side", "right side", "upper", "lower", "top", and "bottom" are all defined based on the relationship between the orientations or positions shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the structure must be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention. In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0040] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0041] A self-stabilizing detection device based on multi-source collaboration and dynamic aerodynamic compensation includes a rotor assembly 1, a drive system 2, a dynamic airflow control assembly 3 and a detection assembly 4 arranged in sequence from top to bottom, wherein the drive system 2 provides power for the rotor assembly 1 and the dynamic airflow control assembly 3, and the battery supplies power to the entire detection device. The dynamic airflow control assembly 3 includes an air cage 31, a fan 32, an air compressor 33, an air chamber 34 and a plurality of air nozzles 35. The air cage 31 is arranged below the drive system 2 and has a plurality of air vents 311 on the air cage 31. The fan 32 is located in the air cage 31 and is driven to rotate by the drive system 2. The air compressor 33 is connected and arranged below the air cage 31. The air chamber 34 is arranged on the circumferential side of the air compressor 33 and is connected to the air outlet of the air compressor 33. A plurality of air nozzles 35 are circumferentially arranged on the outside of the air chamber 34. A control valve is provided between each air nozzle 35 and the air chamber 34.

[0042] The detection component 4 includes a reflection component 41, a detection radar 42 and multiple first infrared cameras 43. The reflection component 41 is an umbrella-shaped structure. The detection radar 42 and multiple first infrared cameras 43 are all located below the reflection component 41. The detection radar 42 and the first infrared cameras 43 both have angle adjustment functions. The reflection component 41 reflects the infrared light emitted by the first infrared camera 43 below it to expand the infrared field of view.

[0043] The air compressor 33 is used to absorb the wind generated by the fan 32 and transmit it to the air chamber 34 .

[0044] The start and stop of the rotor assembly 1 and the dynamic airflow control assembly 3 are controlled by the drive system 2. The drive system 2 is activated to drive the rotor assembly 1 to rotate, so that the entire detection device takes off; the drive system 2 drives the fan 32 to rotate, and the rotation of the fan 32 absorbs external wind or airflow, and then sucks the airflow into the air cage 31. By setting a control valve, the separate control of the multiple air nozzles 35 is achieved, including controlling the start and stop of the air nozzles 35 and the gas flow of each air nozzle 35, further improving the suspension force of the self-stabilizing detection device, and can effectively offset the impact of strong winds on the device when the self-stabilizing detection device is stationary, thereby making the entire detection device have better wind resistance and greatly improving the stability of the entire detection device.

[0045] The self-stabilizing detection device based on multi-source coordination and dynamic aerodynamic compensation of the present invention utilizes aerodynamics, and a plurality of air nozzles 35 spray downwardly, which can effectively increase the load capacity of the entire detection device. Compared with the existing technology, it can carry more complex and high-precision sensors.

[0046] The fan 32 includes a positioning sleeve 321 and a plurality of blades 322 fixed to the outer side of the positioning sleeve 321 along the circumferential direction. The positioning sleeve 321 is a cylindrical structure.

[0047] By providing the reflective component 41 with an umbrella-shaped structure, the field of view limitation of the traditional optical system is broken through and the infrared detection field of view is expanded.

[0048] The detection radar 42 is installed between the plurality of first infrared cameras 43 and uses a millimeter wave radar as a supplementary search method for the first infrared cameras 43. The detection radar 42 can rotate in a circular direction and can also move up and down.

[0049] The angle of each first infrared camera 43 and detection radar 42 is adjustable. For example, a pitch motor 44 is provided to control the pitch angle of the first infrared camera 43, so that the infrared light emitted by the first infrared camera 43 can pass through or not pass through the reflective assembly 41. When the infrared light emitted by the first infrared camera 43 is not reflected by the reflective assembly 41, it can detect and accurately track the target; when it is reflected by the reflective assembly 41, the infrared field of view can be expanded, increasing the detection range of the device.

[0050] The first infrared camera 43 is a medium-wave infrared search camera, which forms a multi-source data fusion framework with the millimeter-wave radar to achieve long-distance search.

[0051] The number of the first infrared cameras 43 can be multiple to increase the detection frequency. When multiple targets are found, some of the first infrared cameras 43 can track while the other first infrared cameras 43 continue searching. The number is preferably four.

[0052] The battery can be installed in the dynamic airflow control assembly 3.

[0053] The rotor assembly 1 is lightweight in design.

[0054] A detachable sealing cover is provided at the bottom of the air chamber 34, which adopts a TPT back plate and silicone composite sealing process, taking into account both maintenance convenience and air tightness requirements.

[0055] A plurality of flow guide channels are arranged inside the air chamber 34, and a plurality of air nozzles 35 are connected to the plurality of flow guide channels. Such a design facilitates the distribution of high-speed airflow in the air chamber 34 by setting the flow guide channels.

[0056] Each air nozzle 35 is rotatably connected to the air chamber 34 via a first rotation adjustment mechanism. This design allows the angle of the air nozzle 35 relative to the air chamber 34 to be adjusted as needed, thereby adjusting the stability and flight angle of the self-stabilizing detection device, and assisting in the mid-air movement of the self-stabilizing detection device. The structure of the first rotation adjustment mechanism can be any conventional structure capable of achieving a rotational connection between two structures and adjusting the rotation angle, and its specific structural composition will not be detailed here.

[0057] The drive system 2 includes a housing 21 and, arranged within the housing 21, a motor 22, an encoder, an inertial navigation module, a gyroscope, a motor connecting shaft 26, and a power shaft 27. The power shaft 27 and the motor connecting shaft 26 are sequentially installed, from the inside out, within the rotor of the motor 22. The rotor assembly 1 is fixed to the top of the power shaft 27 via the rotor connecting shaft 28. The fan 32 is fixed to the bottom of the power shaft 27 via the torque transmission shaft 210. The encoder, inertial navigation module, and gyroscope are all fixed to the housing 21 via an encoder adapter plate 211. The rotor connecting shaft 28 is rotationally connected to the housing 21 via a bearing assembly 29, which includes a pair of angular contact ball bearings and a bearing sleeve. The encoder is used to control the rotation of the motor 22. The gyroscope is used to measure the deflection angle and control the dynamic airflow to ensure stable operation of the drive system 2. The inertial navigation module is used for positioning. The torque transmission shaft 210 is made of a metal material with high structural strength, such as stainless steel, and uses a square structure to transmit torque. The rotor of motor 22 rotates, driving the motor connecting shaft 26 to rotate, which in turn drives the power shaft 27 to rotate. The power shaft 27 synchronously drives the torque transmission shaft 210 and the fan 32. The centrifugal force generated by the rotation of fan 32 draws the external airflow through the air cage 31. After being pressurized by the centrifugal air compressor 33, it is transported along several guide channels in the air chamber 34 to the array of air nozzles 35 for high-speed ejection. The air nozzles 35 combine the wind disturbance data fed back in real time by the gyroscope to achieve the dual effects of airflow momentum compensation and suspension force enhancement. At the same time, the spatial position of the equipment is precisely controlled through vector injection, forming a three-dimensional vector propulsion system. Under static working conditions, the aerodynamic compensation mechanism is triggered by the gyroscope attitude correction algorithm to ensure azimuth stability.

[0058] The reflector assembly 41 includes a mounting base 411, a flexible reflector body 412, and a plurality of angle adjustment brackets 413. The mounting base 411 is fixedly mounted on the bottom end of the dynamic airflow control assembly 3. The plurality of angle adjustment brackets 413 are arranged circumferentially along the mounting base 411. One end of each angle adjustment bracket 413 is rotationally connected to the mounting base 411 via a second rotation adjustment mechanism. One end of the flexible reflector body 412 is rotationally mounted on the bottom end of the dynamic airflow control assembly 3 or the side wall of the mounting base 411. The lower surface of the flexible reflector body 412 is fixedly connected to the plurality of angle adjustment brackets 413. The retraction and extension of the flexible reflector body 412 is controlled by controlling the rotation of the plurality of angle adjustment brackets 413. In this design, the plurality of angle adjustment brackets 413 are preferably evenly distributed along the circumference of the mounting base. The second rotation adjustment mechanism adjusts the vertical rotation angle of the angle adjustment bracket 413, thereby controlling the opening angle of the umbrella-shaped flexible reflective body 412, thereby controlling the retraction and extension of the flexible reflective body 412, and further controlling the reflection angle of the first infrared camera 43 below, thereby adjusting the infrared field of view. The structure of the second rotation adjustment mechanism can be any structure in the prior art that can achieve a rotational connection between two structures and rotation angle adjustment, and its specific structural composition is not repeated here.

[0059] The flexible reflective body 412 comprises a number of radially distributed support frames, a flexible membrane fabric laid out in an umbrella-like pattern and fixed to the support frames, and a reflective film layer coated on the lower surface of the flexible membrane fabric. One end of the support frames is pivotally connected to the bottom of the dynamic airflow control assembly 3 or the sidewall of the mounting base 411. This design, through the use of the flexible membrane fabric, allows the flexible reflective body 412 to maintain a certain shape under the support of the support frames, while also enabling the flexible reflective body 412 to expand and contract with the support frames. The flexible membrane fabric can be positioned above or below the support frames.

[0060] The upper surface of the flexible reflective body 412 is covered with a solar panel, which is connected to a battery. This design, by installing a high-efficiency monocrystalline silicon solar panel array on the upper surface of the flexible reflective body 412, converts solar energy into electrical energy, significantly improving the endurance of the self-stabilizing detection device. The solar panel is staggered relative to the supporting frame.

[0061] The detection component 4 also includes a plurality of precision tracking devices 45 installed above the reflection component 41. Each precision tracking device 45 includes a three-axis stabilized platform 451 and a second infrared camera 452 and a visible light camera 453 installed on the three-axis stabilized platform 451. With this design, the dual-field tracking function of the medium-wave infrared camera and the visible light camera 453 is adopted, and stable tracking is achieved through the three-axis stabilized platform 451 of the bionic chicken neck. The second infrared camera 452, the visible light camera 453 and the three-axis stabilized platform 451 are all existing technologies and will not be described in detail here. After detecting the target, the optimal observation position and posture are reached through movement, and the target is tracked by the second infrared camera 452 and the visible light camera 453 for precision tracking.

[0062] The rotor assembly 1 includes a rotor box 11 and a plurality of rotors 12 evenly distributed along the circumference of the rotor box 11. A center of mass adjustment assembly 13 is provided within the rotor box 11. With this design, the center of mass adjustment assembly 13 can automatically adjust the center of mass of the device, enabling the device to withstand strong winds and effectively addressing aerodynamic instability during high-speed rotation. The center of mass adjustment assembly 13 can be a center of mass adjustment device as known in the art, or it can be in the form of a counterweight. For example, the center of mass adjustment assembly 13 includes a central cylinder and a plurality of counterweights, wherein the central cylinder is fixedly mounted within the rotor box 11, and the plurality of counterweights are distributed circumferentially within an annular channel formed between the central cylinder and the inner wall of the rotor box 11. The dynamic balancing mechanism of the hollow rotor box 11 structure and the adjustable counterweights effectively addresses aerodynamic instability during high-speed rotation. The top cover of the rotor box 11 is provided with a cover to facilitate disassembly, assembly, and maintenance of the center of mass adjustment assembly 13 within the rotor box 11. The number of rotors 12 is preferably four.

[0063] The detection radar 42 is installed between the plurality of first infrared cameras 43 via a vertical telescopic structure 46. With such a design, the height can be adjusted via the vertical telescopic structure 46. The vertical telescopic structure 46 can be, for example, a telescopic rod.

[0064] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
