Description

Technical Field

[0001] This invention relates to the field of airship technology, specifically to an airship detection device with regionally adjustable trajectory and its usage method. Background Technology

[0002] Aerostats are aircraft that rely on buoyancy to ascend and carry detection instruments. Aerostats are a type of aircraft, and commonly use balloons as inflatable bladders. When the density of the gas filling the bladder is less than the density of the surrounding air, and the resulting static buoyancy exceeds the weight of the balloon and its payload, the balloon can ascend. When the system's gravity and buoyancy are balanced, the balloon can remain at a certain altitude. As a platform, the balloon can carry observation instruments and, driven by wind, moves along the direction of atmospheric circulation; its trajectory is generally uncontrollable.

[0003] For example, patent CN201610190895.9 proposes a device for controlling the ascent and descent of a high-altitude balloon and a method for controlling the trajectory of a high-altitude balloon. The buoyancy unit of the high-altitude balloon consists of a skin, a support belt, and support ropes. The volume of the buoyancy unit can be changed by a buoyancy unit volume adjustment device, thereby changing the buoyancy of the high-altitude balloon and controlling its ascent and descent. The trajectory control of the high-altitude balloon is achieved based on the differences in wind speed and direction at different altitudes in the stratosphere. This is a solution that achieves altitude and trajectory control of a high-altitude balloon without releasing the internal buoyant gas, enabling the balloon to remain in a region for extended periods. However, it requires consideration of stratospheric wind speed and direction, necessitates certain natural conditions, and has a long response time and low regional control capability, primarily focusing on vertical position adjustment.

[0004] In natural disasters or other special application scenarios, when continuous monitoring of the terrain or ground environment within a certain area is required, drones are commonly chosen for monitoring. The basic hardware components of a drone include: a flight control computer (flight controller), an aircraft support frame, motors, and rotors. The flight control computer controls the rotor speed and direction to achieve functions such as vertical takeoff and landing, in-situ rotation, and horizontal movement. Specifically, in-situ rotation is achieved by controlling the different speeds and directions of each rotor, resulting in different torques on the left and right sides of the drone in the horizontal direction, thus controlling the drone's horizontal rotation and flight path.

[0005] However, drones have poor endurance, requiring them to return to base for battery replacement, resulting in limited monitoring range, low efficiency, high labor and equipment maintenance costs, and limited takeoff altitude, making them unsuitable for use in mountainous terrain and battlefield monitoring. On the other hand, using balloons to carry monitoring devices is problematic because the horizontal displacement of the balloons is greatly affected by wind, and the monitoring range cannot be controlled, resulting in low controllability of the balloons.

[0006] Existing buoyant detection devices have the following problems: 1) To achieve long-term residence in a designated area, it is necessary to rely on natural conditions such as differences in wind speed and direction at different altitudes in the stratosphere, which is uncontrollable; 2) How to make a miniaturized buoyant detection device move within a certain area, adjust the horizontal displacement of the buoyant detection device to ensure real-time monitoring of the designated area, and at the same time rise to a sufficient height to avoid being detected. Summary of the Invention

[0007] To address the aforementioned problems and shortcomings, and to solve the issues of floating detection devices being far from their detection range and losing directional control, this invention provides a floating detection device with regionally adjustable trajectory and its usage method, enabling efficient use and effective concealment of miniaturized high-altitude detection devices.

[0008] An airborne detection device with regionally adjustable trajectory includes a buoyancy unit, a power supply unit, a thrust unit, a truss, and a detection control unit.

[0009] The buoyancy unit includes a gas-fillable cavity. The top of the buoyancy unit is connected to a truss, and the bottom is connected to a detection and control unit. After the cavity is filled with light gas, it drives the entire buoyancy detection device to rise into the air.

[0010] The detection and control unit is connected to the buoyancy unit and the truss, and includes a control chip and detection devices. The detection devices include a wind direction and speed meter and a satellite locator, used to collect data and transmit it to the control chip for processing and to issue control signals.

[0011] The truss is ring-shaped and, when floating, surrounds the buoyancy unit. The truss is equipped with a power supply unit and a thrust unit, and is connected to the detection and control unit.

[0012] The power supply unit is connected to the thrust unit and provides energy to the thrust unit.

[0013] The thrust unit includes multiple thrusters distributed on the truss; each thruster includes a motor and a propeller, with the propeller fixed to the truss via a drive shaft; based on the control signal given by the detection and control unit, the start, stop, and speed of the specific thrusters are controlled to output differential speed, driving the entire floating detection device to rotate differentially, achieving displacement deflection, and allowing the floating detection device to return to the designated area.

[0014] Furthermore, the thruster can be individually controlled for its start, stop, and rotation speed; the propeller is a counter-rotating propeller, providing torque in different directions through forward and reverse rotation; both can be used individually or together to achieve 360-degree omnidirectional movement control of the buoyant detection device in the horizontal direction.

[0015] Furthermore, the gas-fillable cavity is an overpressure balloon, which has multiple independent membranes extending from the top to the bottom to fix the expansion volume of the overpressure balloon. Each membrane has a reinforcing rib extending from the top to the bottom of the balloon along its edge. Each reinforcing rib has a contraction rope that controls small-range volume changes of the overpressure balloon. The lower end of the contraction rope is connected to a flexible contraction component.

[0016] Furthermore, the flexible shrinkage assembly includes: a rope-retracting wheel and a lightweight outer shell. The rope-retracting wheel is located inside the lightweight outer shell and rotates coaxially with the overpressure balloon. Each shrinkage rope is fixedly connected to the rope-retracting wheel. When the rope-retracting wheel rotates, the shrinkage rope is pulled tight and wrapped around the rope-retracting wheel, compressing the volume of the overpressure balloon.

[0017] Furthermore, the rope-reeling reel has a winding wheel in the middle, and the winding wheel has a rope connected to the wind-catching bag. The length of the rope controls the release distance of the wind-catching bag.

[0018] Furthermore, the wind-catching bag is conical when it is blown, and the end of the rope has three connectors to the wind-catching bag, so that the wind-catching bag can adjust its wind-catching direction according to the wind direction.

[0019] Furthermore, the detection device also includes a temperature sensor and a pressure sensor to collect relevant data, which is then analyzed and processed by the control chip to send control signals to the thrust unit; or transmitted as mission data to the receiving device.

[0020] Furthermore, the power supply unit includes a solar panel and an energy storage battery. The solar panel converts solar energy into electrical energy and stores it in the energy storage battery, providing the necessary electrical energy to the thrust unit and the detection and control unit when needed.

[0021] The method of using the aforementioned navigable, locally adjustable trajectory airborne detection device includes:

[0022] Step 1: Set the floating area of ​​the floating detection device according to the coordinates through the software program, upload it to the detection control unit of the floating detection device, fill it with the set amount of gas, open the ground mooring facilities, and the floating detection device will take off.

[0023] Step 2: After reaching the set altitude, the detection and control unit starts to detect, collect and transmit the mission data in real time to the ground receiving equipment.

[0024] Step 3: When the floating detection device detects a distance of 20m from the boundary of the set flight area, the detection control unit analyzes the data and outputs a signal to activate the corresponding thrust unit based on the analysis results. This activates the differential output of the thruster, changes the direction of travel of the floating detection device, and controls it to return to the set flight area. When the floating detection device does not float to the boundary of the set flight area, the thrust unit is not activated, and it floats freely to carry out detection work.

[0025] Furthermore, the mission data includes image data, multispectral data, etc., and the data can be transmitted to ground receiving equipment in real time via satellite link.

[0026] Furthermore, the detection and control unit obtains stratospheric wind speeds at different altitudes through underground equipment, thereby controlling the descent height of the wind-catching bag. This creates a speed difference between the wind-catching bag and the overpressure balloon due to the different wind speeds, thus generating traction between the wind-catching bag and the overpressure balloon and preventing the overpressure balloon from being blown out of the designated flight area.

[0027] Furthermore, the detection and control unit obtains stratospheric wind speeds at different altitudes through underground equipment. By rotating the rope-retracting wheel, the volume of the overpressure balloon can be reduced, thereby adjusting the flight altitude of the overpressure balloon and preventing it from being pushed out of the designated flight area.

[0028] Furthermore, when the floating detection device detects a distance of 20m from the boundary of the set flight area, the detection control unit activates the corresponding thrust unit based on the data analysis results when the wind force is detected to be level 0, 1, 2, 3, or 4; when the wind force is detected to be level 5, the thrust unit is activated intermittently; when the wind force is detected to be level 6, the thrust unit is not activated to prevent damage from starting against the wind.

[0029] Furthermore, the differential output is a command calculated by the detection and control unit and transmitted to each thruster, giving different rotation speeds to thrusters at different positions, enabling the device to turn while moving, resist wind force, and return to the set flight area.

[0030] The present invention has the following technical effects:

[0031] 1. This invention uses the buoyancy provided by balloons to lift the device into the air, which reduces the device's own weight, making the device more compact and suitable for use in mountainous terrain and emergency situations. In addition, balloons are inexpensive, which can effectively reduce the manufacturing cost of the device and facilitate large-scale use.

[0032] 2. This invention achieves flexible shrinkage of the overpressure balloon's volume by setting retractable ropes between the diaphragms, allowing the overpressure balloon to float within a small height range, effectively reducing the device's drift away from the detection range. Simultaneously, the wind-catching bag acts like an anchor in the air. By lowering the wind-catching bag to a certain distance and placing it at a different wind speed than the overpressure balloon, the difference in their speeds creates mutual tension, achieving position control of the overpressure balloon. The control structure is simple, easy to use, and lightweight, without adding weight to the flight, while also providing adjustable control within a controllable range.

[0033] 3. This invention adjusts the direction of the device by controlling the thrust device that is activated intermittently, thereby enabling the device to freely probe within a set range, improving detection efficiency and accuracy; at the same time, the thrust device is activated only when approaching the boundary of the set flight area, which can effectively reduce power consumption, allowing long-term self-sufficiency in power supply by solar panels alone; it not only controls the freely floating detection device within a certain range, but also achieves the purpose of lightweight device and saves costs.

[0034] In summary, this invention, by equipping the buoyant detection device with a satellite positioning device and a detection control unit, supplemented by a horizontally omnidirectional thruster, and combining the data processing results of the detection control unit with preset data to automatically control the thruster to start intermittently, can better solve the problem of the detection device drifting out of the detection range. Simultaneously, by using solar panels for sustainable power supply, it further improves the device's service life and overall utilization rate. Furthermore, this invention also provides optimized solutions for the overpressure balloon with a retraction rope, the wind-catching bag, and the structure and materials, ultimately achieving a more easily controllable, lighter, more flexible, and lower-cost buoyant detection device.

Detailed Implementation

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0044] like Figure 1-6 As shown, this is the buoyant detection device with regionally adjustable trajectory according to the present invention. Figure 1 This is a front view of the structure. Figure 2 This is a front view of the structure. Figure 3 This is a top view of the structure.

[0045] An airborne detection device with regionally adjustable trajectory includes a buoyancy unit 1, a power supply unit 2, a thrust unit 3, a truss 4, and a detection and control unit 5;

[0046] The buoyancy unit 1 includes a gas-fillable cavity, which provides buoyancy to lift the device into the air. The buoyancy unit 1 is connected to the detection control unit 5 and the truss 4. The detection control unit 5 is connected to the lower end of the buoyancy unit 1 and includes a control chip and a detection device. The control chip controls the detection device to perform detection and information collection, as well as to transmit information with the ground control device.

[0047] The truss 4 is made of lightweight, high-strength carbon fiber material and surrounds the buoyancy unit 1. The truss 4 is equipped with a power supply unit 2 and a thrust unit 3. The truss 4 is used to support the power supply unit 2 and the thrust unit 3, and at the same time provides support and a balancing platform. The power supply unit 2 is connected to the thrust unit 3. The thrust unit 3 includes multiple thrusters symmetrically distributed on the truss 4. The thrusters include a motor and a propeller 7. The propeller 7 is fixed to the truss 4 through a transmission shaft. The rotation speed of each thruster is individually controlled by the chip of the detection and control unit. By setting the rotation speed of a specified thruster through the signal given by the detection and control unit, the thruster is started to generate differential rotation, thereby realizing the displacement and deflection of the device and allowing the device to return to the designated area.

[0048] Based on the above embodiments, further, the gas-fillable cavity is a low-cost overpressure balloon 101. The overpressure balloon 101 is provided with multiple independent diaphragms 1011 extending from the top to the bottom. Each diaphragm 1011 has a reinforcing rib extending from the top to the bottom of the balloon along its edge. Each reinforcing rib has a retraction rope 1012 that controls the small-range volume change of the overpressure balloon 101. The lower end of the retraction rope 1012 is connected to a flexible retraction component. The small overpressure balloon 101 can rise quickly, is easy to carry, and is inexpensive, which is conducive to rapid detection by launching a large number of balloons at once. The overpressure balloon 101 adjusts its ascent height by adjusting its size, and the retraction rope 1012 controls the overpressure balloon 101 to float within a small range of height, avoiding strong winds and preventing it from being blown away from the detection area.

[0049] Based on the above embodiments, the flexible shrinkage assembly 102 further includes a rope-retracting wheel 1021 and a lightweight outer shell 1022. The rope-retracting wheel 1021 is disposed inside the lightweight outer shell 1022. The rope-retracting wheel 1021 rotates coaxially with the overpressure balloon 101. Each shrinkage rope 1012 is fixedly connected to the rope-retracting wheel 1021. When the rope-retracting wheel 1021 rotates, the shrinkage rope 1012 is pulled tight and wrapped around the rope-retracting wheel 1021, compressing the volume of the overpressure balloon 101.

[0050] Based on the above embodiments, further, the rope winding wheel 1021 has a winding wheel 1023 with a rope wound in the middle. The rope is connected to the wind-catching bag 8. The release distance is controlled by the length of the rope. By placing the wind-catching bag 8 at different wind speeds, the wind speeds experienced by the overpressure balloon 101 and the wind-catching bag 8 are different, so that the wind-catching bag 8 pulls on the overpressure balloon 101 to prevent it from being blown away from the detection area.

[0051] Based on the above embodiments, the wind-catching bag 8 (made of nylon) is conical when blowing air, and the end of the rope is connected to three points on the wind-catching bag 8. The wind-catching bag 8 can automatically adjust the wind-catching direction according to the wind direction. The nylon material has high wear resistance and anti-static properties, which is beneficial for long-term use.

[0052] Based on the above embodiments, the detection device further includes: a temperature sensor, a pressure sensor, a wind direction and speed meter, and a Beidou satellite locator; it can detect and collect data on real-time temperature, pressure, wind speed and wind direction, and can locate the balloon's position and boundary position at any time through the Beidou satellite locator.

[0053] Based on the above embodiments, the truss 4 is a lightweight and high-strength annular truss 4, with the upper end of the annular truss 4 connected to the buoyancy unit 1 and the lower end connected to the detection and control unit 5; the lightweight and high-strength structure not only has compressive strength, but also makes the device lighter and easier to carry.

[0054] Based on the above embodiments, the truss 4 is made of carbon fiber material. Carbon fiber material can withstand low temperatures, has good stability, good fatigue resistance, and corrosion resistance, and has a long service life, which is conducive to the stable use of the device in high-altitude environments.

[0055] Based on the above embodiments, the power supply unit 2 further includes a solar panel 6 and an energy storage battery. The solar panel 6 converts solar energy into electrical energy and stores it in the energy storage battery. When needed, it provides the required electrical energy to the thrust unit 3 and the detection and control unit 5. The device generates electrical energy through the solar panel 6. When the device is floating normally, it stores the electrical energy in the energy storage battery. When the device is detected to be drifting out of the set flight area, the energy storage battery provides electrical energy to start the thruster. The intermittent power supply to the thruster can ensure sufficient electrical energy while reducing the weight of the power supply equipment.

[0056] Based on the above embodiments, the propeller 7 is further described as a forward and reverse propeller 7, which provides torque in different directions by rotating forward and reverse, thereby increasing the adjustable range of the device; the forward and reverse propeller 7 can rotate forward and reverse, providing more differential speed situations and coping with more device angle adjustment situations.

[0057] Figure 7 This is a flowchart illustrating the usage method of the airborne detection device with regionally adjustable trajectory according to the present invention. Figure 7 As shown, the method of using the regionally adjustable trajectory-controlled aerial detection device includes:

[0058] Step 1: Arrange the device according to... Figure 1 Assemble as shown, then power on the buoyant detection device and test whether the equipment is normal. Test the hardware and software; test whether the system is powered on and whether the feedback from various sensors is normal, whether the control and feedback of the thrust components are normal, and whether the operation feedback of the onboard equipment is normal; software testing includes: whether the map setting feedback is normal, whether the navigation and positioning display is normal; warning effect test, input the positioning information of the sphere, test whether the system feedback is normal, and proceed to the next step after the preliminary test is normal.

[0059] Step 2: After the pre-test is completed, power on the detection control unit 5 to perform information detection and transmission. If the ground control equipment detects and receives normal data, the device is normal and can proceed to the next step. Set the flight area and upload it to the detection control unit 5 of the buoyant detection device to determine the flight range. Connect to the interface of the overpressure balloon 101 and fill the overpressure balloon 101 with helium. Calculate the corresponding amount of helium according to the altitude at which it will take off. After the helium filling is completed, seal the inflation port and let the buoyant detection device take off.

[0060] Step 3: During the ascent, the detection and control unit 5 operates normally and detects and collects real-time wind speed, temperature, pressure, altitude, and satellite positioning information, transmitting the information to the ground control equipment via satellite.

[0061] Step 4: Upon reaching the set altitude, the detection and control unit 5 begins to detect, collect, and transmit ground data in real time.

[0062] Step 5: When the floating detection device detects a distance of 20m from the boundary of the set flight area, the detection control unit 5 controls the system to calculate data and output a signal to activate the thrust unit 3, which outputs differential speed to multiple thrusters to change the direction of travel of the device and control the device to return to the set flight area; when the floating detection device does not float to the boundary of the set flight area, the device floats freely to carry out detection work.

[0063] Based on the above embodiments, the detection and control unit 5 further obtains the stratospheric wind speed at different altitudes through underground equipment. When it is detected that it is difficult to return to the set area by relying on the thruster control, the wind-catching bag 8 is controlled to descend to the specified height through the wind speed of the lower stratospheric layer detected by the underground equipment. This creates a speed difference between the wind-catching bag 8 and the overpressure balloon 101 due to the different wind speeds, thereby creating a traction force between the wind-catching bag 8 and the overpressure balloon 101, preventing the overpressure balloon 101 from being blown out of the set flight area by the wind, and assisting the thruster to return to the set flight area.

[0064] Based on the above embodiments, the detection and control unit 5 can further obtain the stratospheric wind speed at different altitudes through underground equipment, and by rotating the rope winding wheel 1021, the retraction rope 1012 is wound onto the rope winding wheel 1021, thereby shrinking the volume of the overpressure balloon 101 and adjusting the flight altitude of the overpressure balloon 101 to prevent it from being pushed out of the set flight area.

[0065] Based on the above embodiments, further, when the floating detection device 5 detects a distance of 20m from the boundary of the set flight area, the detection control unit detects wind force of level 0, 1, 2, 3, or 4 and activates the corresponding thrust unit 3 according to its data analysis results; when the wind force is detected to be level 5, the thrust unit 3 is activated intermittently, and the flight speed of the overpressure balloon 101 is comprehensively controlled in conjunction with the retraction component 102 and the wind-catching bag 8; when the wind force is detected to be level 6, the thrust unit is not activated to prevent damage from starting against the wind.

[0066] As can be seen from the above embodiments, this invention adjusts the device's position using an intermittently usable differential thruster, ensuring the device can perform detection work within a certain area. This effectively improves the controllability of the wireless detection device and extends its service life. Furthermore, by using a balloon to provide buoyancy, the device's weight and cost are reduced, as are recovery costs, making it suitable for use in mountainous terrain and special emergency situations. The design of activating the differential thruster only when the device floats out of the designated area effectively reduces energy consumption; only the solar panel 6 is needed, making the device lighter, more flexible, and less expensive.
