Description

Technical Field

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

[0002] The marine monitoring field poses strict requirements for the continuous operation ability in extreme environments: the marine law enforcement department needs to achieve continuous monitoring of designated sea areas, and there is an urgent need for the deployment of meteorological monitoring equipment in the typhoon eye area. The existing technical system has the following limitations: the traditional rigid mechanical coupling turntable system has structural defects. Its fixed installation mode at the dock results in a fixed monitoring area and is difficult to be deployed in deep sea; in sea conditions of medium level and above, the shipborne bracket causes the failure of dynamic load compensation, resulting in a significant degradation of the spatial resolution of the imaging system and a decrease in the stability of inertial sensitive elements; limited by the physical constraint of the field of view angle of optical components, the target capture probability has a significant attenuation. There are also devices for monitoring by drones in the prior art. However, first, the marine meteorological conditions are complex and changeable, and severe weather such as strong wind, heavy rain, and thick fog will seriously affect the flight safety and monitoring effect of drones. Especially, the wind resistance performance of drones is weak, and strong wind may cause drones to deviate from the predetermined route or even be unable to fly normally; second, the volume and load capacity of drones are relatively limited, and it is difficult to carry a variety of complex and high-precision sensors, resulting in certain limitations in the types and accuracy of environmental data obtained; third, the coverage area of drones is small. For a large area of sea area, if large-area monitoring is to be achieved, multiple drones need to act simultaneously or a single drone needs to make multiple round trips, which affects the monitoring efficiency and results in a high monitoring cost; fourth, the battery life of drones is limited. Once the battery runs out, it may cause the drone to fall, resulting in equipment damage and even safety accidents.

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

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

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A self-stabilizing detection device based on multi-source collaboration and dynamic pneumatic compensation, comprising a rotor assembly, a drive system, a dynamic airflow control assembly, and a detection assembly arranged in sequence from top to bottom. Among them, the drive system provides power for the rotor assembly and the dynamic airflow control assembly, and a storage battery supplies power to the entire detection device. The dynamic airflow control assembly includes an air cage, a fan, an air compressor, an air chamber, and a number of air nozzles. The air cage is arranged below the drive system and is provided with a number of ventilation holes. The fan is located inside 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 communicated with the air outlet of the air compressor. A number of air nozzles are circumferentially arranged outside the air chamber, and a control valve is arranged between each air nozzle and the air chamber. The detection assembly includes a reflection assembly, a detection radar, and a number of first infrared cameras. The reflection assembly has an umbrella-like structure. The detection radar and a number of first infrared cameras are both located below the reflection assembly, and both the detection radar and the first infrared cameras have an angle adjustment function. The infrared light emitted by the first infrared cameras below is reflected by the reflection assembly to expand the infrared field of view.

[0006] Furthermore, a number of flow guiding channels are arranged inside the air chamber, and a number of air nozzles are correspondingly communicated with a number of flow guiding channels.

[0007] Furthermore, each air nozzle is rotatably connected to the air chamber through a first rotation adjustment mechanism.

[0008] 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 inside the housing. Among them, the power shaft and the motor connecting shaft are sequentially installed inside the rotor of the motor from inside to outside. The rotor assembly is fixedly installed at the top of the power shaft through a rotor connecting shaft. The fan is fixedly installed at the bottom of the power shaft through a torque transmission shaft. The encoder, the inertial navigation module, and the gyroscope are all fixedly installed inside the housing through an encoder adapter board.

[0009] Furthermore, the reflection assembly includes a mounting base, a flexible reflection body, and a number of angle adjustment brackets. Among them, the mounting base is fixedly installed at the bottom of the dynamic airflow control assembly. A number of angle adjustment brackets are arranged circumferentially along the mounting base, and one end of each angle adjustment bracket is rotatably connected to the mounting base through a second rotation adjustment mechanism. One end of the flexible reflection body is rotatably installed at the bottom 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 a number of angle adjustment brackets. The retraction and release control of the flexible reflection body is realized by controlling the rotation of a number of angle adjustment brackets.

[0010] Further, the flexible reflection body includes a number of support skeletons distributed radially, a flexible membrane laid in an umbrella shape and fixed on the number of support skeletons, and a reflection film layer plated on the lower surface of the flexible membrane. One end of the number of support skeletons is rotatably connected to the bottom end of the dynamic air flow control component or the side wall of the installation base.

[0011] Further, a solar panel is paved on the upper surface of the flexible reflection body, and the solar panel is connected to a storage battery.

[0012] Further, the detection component further includes a number of fine tracking devices installed above the reflection component. Each fine tracking device includes a three-axis stabilization platform, a second infrared camera and a visible light camera installed on the three-axis stabilization platform.

[0013] Further, the rotor assembly includes a rotor box and a number of rotors evenly distributed along the circumference of the rotor box. A centroid adjustment component is arranged inside the rotor box.

[0014] Further, the detection radar is installed between a number of first infrared cameras through a vertical telescopic structure.

[0015] The present invention has the following effects compared with the prior art: By controlling the start and stop of the rotor assembly and the dynamic air flow control component through the drive system, when the drive system operates, it drives the rotor assembly to rotate, so that the entire detection device takes off; the drive system drives the fan to rotate, and the fan rotates to absorb external wind or air flow, and then sucks the air flow into the air cage. By setting control valves, the separate control of a number of air nozzles is realized, including controlling the start and stop of the air nozzles and the gas flow rate of each air nozzle, further improving the suspension force of the self-stabilizing detection device, effectively offsetting the influence of strong wind on the device when the self-stabilizing detection device is stationary, and further making the entire detection device have better wind resistance performance and greatly improving the stability of the entire detection device.

[0016] The self-stabilizing detection device based on multi-source cooperation and dynamic pneumatic compensation of the present invention utilizes aerodynamics, and a number of air nozzles jet downward, which can effectively increase the load capacity of the entire detection device. Compared with the prior art, it can carry more complex and high-precision sensors.

[0017] By setting a reflection component with an umbrella shape, the field of view limitation of the traditional optical system is broken through, and the infrared detection field of view is expanded.

[0018] The detection radar is installed between a number of first infrared cameras as a supplementary search method for the search of the first infrared cameras.

[0019] The angle of each first infrared camera is adjustable, enabling the infrared light emitted by the first infrared camera to pass through or not pass through the reflection of the reflection component. When the infrared light emitted by the first infrared camera does not pass through the reflection of the reflection component, detection and precise tracking of the target can be achieved; when it passes through the reflection of the reflection component, the infrared field of view can be expanded, increasing the detection range of the device.

[0020] The number of first infrared cameras being multiple can increase the detection frequency. After multiple targets are detected, some of the first infrared cameras can be used for tracking while the other part continues to search. Description of the Drawings

[0026] A self-stabilizing detection device based on multi-source collaboration and dynamic pneumatic compensation, comprising 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. Among them, the drive system 2 provides power for the rotor assembly 1 and the dynamic airflow control assembly 3, and the entire detection device is powered by a storage battery. 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 a plurality of ventilation holes 311 are opened on the air cage 31. The fan 32 is located inside 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 periphery of the air compressor 33 and is communicated with the air outlet of the air compressor 33. A plurality of air nozzles 35 are circumferentially arranged outside the air chamber 34, and a control valve is arranged between each air nozzle 35 and the air chamber 34. The detection assembly 4 includes a reflection assembly 41, a detection radar 42, and a plurality of first infrared cameras 43. The reflection assembly 41 has an umbrella-like structure. The detection radar 42 and the plurality of first infrared cameras 43 are both located below the reflection assembly 41, and both the detection radar 42 and the first infrared cameras 43 have an angle adjustment function. The infrared light emitted by the first infrared cameras 43 below is reflected by the reflection assembly 41 to expand the infrared field of view.

[0027] The air compressor 33 is used to absorb the wind generated by the fan 32 and transfer it to the air chamber 34.

[0028] By controlling the start and stop of the rotor assembly 1 and the dynamic airflow control assembly 3 through the drive system 2, when the drive system 2 operates, it drives the rotor assembly 1 to rotate, causing the entire detection device to take off; the drive system 2 drives the fan 32 to rotate, and the fan 32 rotates to absorb the external wind or airflow, and then sucks the airflow into the air cage 31. By setting the control valves, the separate control of the plurality of air nozzles 35 can be realized, including controlling the start and stop of the air nozzles 35 and the gas flow rate of each air nozzle 35, further improving the suspension force of the self-stabilizing detection device, effectively offsetting the influence of strong winds on the device when the self-stabilizing detection device is stationary, and thus enabling the entire detection device to have better wind resistance performance and greatly improving the stability of the entire detection device.

[0029] In the self-stabilizing detection device based on multi-source collaboration and dynamic pneumatic compensation of the present invention, by utilizing aerodynamics, the plurality of air nozzles 35 jet downward, which can effectively increase the load capacity of the entire detection device. Compared with the prior art, it can carry more complex and high-precision sensors.

[0031] By setting the reflecting component 41 of the umbrella structure, the field-of-view limitation of the traditional optical system is broken through, and the infrared detection field of view is expanded.

[0032] The detection radar 42 is installed between multiple first infrared cameras 43. A millimeter-wave radar is adopted as a supplementary search method for the search of the first infrared cameras 43. The detection radar 42 can rotate circumferentially and can also move up and down.

[0033] The angles of each first infrared camera 43 and the detection radar 42 are adjustable. For example, by setting the pitching motor 44 to control the pitching angle of the first infrared camera 43, the infrared light emitted by the first infrared camera 43 can pass through or not pass through the reflection of the reflecting component 41. When the infrared light emitted by the first infrared camera 43 does not pass through the reflection of the reflecting component 41, the detection and precise tracking of the target can be realized; when it passes through the reflection of the reflecting component 41, the infrared field of view can be expanded and the detection range of the device can be increased.

[0034] The first infrared camera 43 is a mid-wave infrared search camera. A multi-source data fusion framework is formed by using the mid-wave infrared search camera and the millimeter-wave radar to achieve long-distance search.

[0035] The number of the first infrared cameras 43 is multiple, which can increase the detection frequency. When multiple targets are found, some of the first infrared cameras 43 can be used for tracking, and the other part of the first infrared cameras 43 can continue to search. The number is preferably four.

[0036] The storage battery can be installed in the dynamic air flow control component 3.

With such a design, by setting the diversion channels, the distribution of the high-speed air flow in the air chamber 34 is facilitated.

[0040] Each air nozzle 35 is rotationally connected to the air chamber 34 through a first rotation adjustment mechanism. With such a design, by setting the first rotation adjustment mechanism, the air nozzle 35 can be adjusted in angle on the air chamber 34 as needed, thereby realizing the adjustment of the stability of the self-stabilizing detection device, the adjustment of the flight angle of the self-stabilizing detection device, and assisting the self-stabilizing detection device to move in the air. The structure of the first rotation adjustment mechanism is any structure in the prior art that can realize the rotational connection and rotational angle adjustment between two structures, and the specific structure composition thereof will not be described in detail here.

[0041] The drive system 2 includes a housing 21 and a motor 22, an encoder, an inertial navigation module, a gyroscope, a motor connecting shaft 26 and a power shaft 27 arranged inside the housing 21.

The rotor wing assembly 1 is fixedly installed at the top end of the power shaft 27 through a rotor wing connecting shaft 28, and the fan 32 is fixedly installed at the bottom end of the power shaft 27 through a torque transmission shaft 210. The encoder, the inertial navigation module and the gyroscope are all fixedly installed inside the housing 21 through an encoder adapter plate 211. The rotor wing connecting shaft 28 is rotatably connected to the housing 21 through a bearing assembly 29, and the bearing assembly 29 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, that is, the gyro, is used to measure the deflection angle. By controlling the dynamic airflow power, the drive system 2 is controlled to make the system work smoothly. The inertial navigation module is used for positioning. The torque transmission shaft 210 is made of a metal material with relatively high structural strength such as stainless steel, and the torque is transmitted by a square structure. The rotation of the rotor of the motor 22 drives the rotation of the motor connecting shaft 26, and then drives the rotation of the power shaft 27. The power shaft 27 synchronously drives the torque transmission shaft 210 and the fan 32. The centrifugal force generated by the rotation of the fan 32 sucks the external airflow through the air cage 31, and after being pressurized by the centrifugal air compressor 33, it is transported along several diversion channels in the air chamber 34 to the air nozzle 35 array and sprayed out at high speed. The air nozzle 35 combines the wind disturbance data real-time feedback by the gyroscope to achieve the dual effects of airflow momentum compensation and suspension force enhancement. At the same time, the spatial pose of the device is precisely controlled through vector injection to form a three-dimensional vector propulsion system. Under static conditions, relying on the gyroscope attitude correction algorithm to trigger the pneumatic compensation mechanism to ensure azimuth stability.

The lower surface of the flexible reflection body 412 is fixedly connected to the plurality of angle adjustment brackets 413. The retraction and deployment control of the flexible reflection body 412 is realized by controlling the rotation of the plurality of angle adjustment brackets 413. With such a design, preferably, the plurality of angle adjustment brackets 413 are evenly distributed circumferentially along the mounting base. The up-and-down rotation angle of the angle adjustment bracket 413 is adjusted through the second rotation adjustment mechanism, and then the opening angle of the umbrella-shaped flexible reflection body 412 is controlled, so as to realize the retraction and deployment control of the flexible reflection body 412, and further control the reflection angle of the first infrared camera 43 below and adjust the infrared field of view. The structure of the second rotation adjustment mechanism is any structure in the prior art that can realize the rotational connection and rotational angle adjustment between two structures, and its specific structural composition will not be elaborated here.

One end of the plurality of support skeletons is rotatably connected to the bottom end of the dynamic air flow control component 3 or the side wall of the mounting base 411. With such a design, by using the flexible membrane cloth, the flexible reflection body 412 can have a certain shape retention ability under the support of the plurality of support skeletons, and can also have the ability to expand and contract and deform along with the plurality of support skeletons. The flexible membrane cloth can be above the support skeletons or below the support skeletons.

[0044] Solar panels are paved on the upper surface of the flexible reflection body 412, and the solar panels are connected to a storage battery. With such a design, by paving an array of high-efficiency monocrystalline silicon solar panels on the upper surface of the flexible reflection body 412, solar energy is converted into electrical energy, greatly improving the battery life of the self-stabilizing detection device.

The second infrared camera 452, the visible light camera 453 and the three-axis stabilization platform 451 are all prior arts and will not be elaborated here. After detecting the target, the device moves to the optimal position and attitude for observation, and the target is tracked by the second infrared camera 452 and the visible light camera 453 for fine tracking.

[0046] 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 centroid adjustment component 13 is arranged inside the rotor box 11. With such a design, the centroid adjustment component 13 can automatically adjust the centroid of the device, enabling the device to have the ability to resist strong winds and effectively solving the problem of aerodynamic instability in the high-speed rotation state.
