Description

Technical Field

[0001] The present invention belongs to the field of unmanned aerial vehicles, and specifically relates to a system for the persistent flight of an integrated circuit adaptive thermal control unmanned aerial vehicle. Background Art

[0002] With the continuous development and growth of the unmanned aerial vehicle industry, unmanned aerial vehicles have gradually begun to be applied in aerial photography, agriculture, plant protection, WeChat selfies, express delivery, disaster relief, wildlife observation, monitoring of infectious diseases, surveying and mapping, news reporting, power line inspection, disaster relief, and film and television shooting.

[0003] The driving methods of unmanned aerial vehicles are mainly electric drive and internal combustion engine drive. Currently, electric drive unmanned aerial vehicles mainly have a multi-rotor structure, which is driven by a self-contained battery to drive a DC motor, and the motor drives the rotor to generate lift to achieve the movement of the unmanned aerial vehicle. Each DC motor is equipped with a DC motor speed control circuit, and the rotation speed and torque of each rotor are dynamically adjusted through computer control, so as to achieve various movements of the unmanned aerial vehicle such as ascending, descending, translating, and turning. Due to the limitations of current battery technology, the self-contained battery of the unmanned aerial vehicle cannot store a large amount of energy, thus restricting the endurance time of the unmanned aerial vehicle.

[0004] Using unmanned aerial vehicles for agricultural inspection and pest control operations can not only improve work efficiency, but also avoid damage to crops, and unmanned aerial vehicles are very suitable for small-area spraying and pest control operations. Intelligent unmanned aerial vehicles for agriculture are widely used and can timely transmit agricultural plant protection information.

[0005] However, when the unmanned aerial vehicle is used outdoors, the battery and other components of the unmanned aerial vehicle, such as chips, will generate heat according to the usage duration. If the heat of the components cannot be processed in time, on the one hand, it will affect the performance of the unmanned aerial vehicle, and on the other hand, in the case of long-term overheating of the components, the service life will be shortened, affecting the persistent flight of the unmanned aerial vehicle.

Specific Embodiments

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Unmanned aerial vehicle, abbreviated as "UAV" ("Unmanned Aerial Vehicle"), is an unpiloted aircraft controlled by radio remote control equipment and self-contained program control devices. In fact, UAV is a general term for unpiloted aircraft. From a technical perspective, it can be classified into: unmanned fixed-wing aircraft, unmanned vertical takeoff and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parasol-wing aircraft, etc. Compared with manned aircraft, it has the advantages of small size, low cost, convenient use, low requirements for the combat environment, and strong battlefield survivability. Due to the important significance of unmanned aerial vehicles for future air combat, the world's major military powers are stepping up the research and development of unmanned aerial vehicles. In November 2013, the Civil Aviation Administration of China (CA) issued the "Interim Provisions on the Management of Pilots of Civil Unmanned Aerial Vehicle Systems", and the China AOPA Association is responsible for the relevant management of civil UAVs. According to the "Provisions", UAV operations can be divided into 11 situations according to the type size and flight airspace. Among them, only UAVs over 116 kg and airships over 4,600 cubic meters flying in the integrated airspace are managed by the Civil Aviation Administration. In other cases, including the increasingly popular micro-aerial photography aircraft, other flights are managed by industry associations or the operators themselves.

[0036] The related technologies of UAVs at home and abroad have developed rapidly. The UAV system has a wide variety of types and distinct uses, resulting in significant differences in many aspects such as size, mass, range, endurance, flight altitude, flight speed, and tasks. Due to the diversity of UAVs, there are different classification methods for different considerations:

[0037] Classified by the configuration of the flight platform, UAVs can be divided into fixed-wing UAVs, rotary-wing UAVs, unmanned airships, parafoil UAVs, flapping-wing UAVs, etc. Fixed-wing flight mode: Similar to traditional airplanes, it generates lift through fixed wings and airflow. It has a high flight speed and long endurance, and is suitable for long-distance tasks such as surveying and mapping, and patrol. The disadvantage is that it requires a runway for takeoff and landing and cannot hover. For example: traditional fixed-wing UAVs. Rotary-wing flight mode: It takes off and lands vertically through rotating propellers, can hover, and is flexible in operation. It is commonly used in tasks such as photography and express delivery. The disadvantage is that its flight speed and endurance are relatively short. For example: multi-rotor UAVs, helicopter UAVs. Fixed-wing and rotary-wing staged working mode flight: The rotary-wing is used for takeoff and landing, and switches to the fixed-wing mode during cruising, combining the flexibility of the rotary-wing and the efficiency of the fixed-wing, suitable for long-duration cruising and vertical takeoff and landing tasks. For example: tilt-rotor UAVs, tail-sitter UAVs, "quadcopter + fixed-wing" composite UAVs. Fixed-wing and rotary-wing simultaneous working mode flight: The fixed-wing and rotary-wing work together, with the capabilities of vertical takeoff and landing, hovering, and long-distance flight. During the entire flight process of this type of UAV, the fixed-wing and rotary-wing can work together simultaneously. This type of UAV is more flexible and suitable for complex operating environments. For example: lift-wing multi-rotor, short-wing "quadcopter + fixed-wing" composite UAVs. Flying through air buoyancy, such as: airships. Flying through flapping wings, such as: flapping-wing aircraft.

[0038] Classified by application, UAVs can be divided into military UAVs and civilian UAVs. Military UAVs can be divided into reconnaissance UAVs, decoy UAVs, electronic countermeasure UAVs, communication relay UAVs, unmanned fighter jets, and target drones, etc.; civilian UAVs can be divided into inspection / surveillance UAVs, agricultural UAVs, meteorological UAVs, exploration UAVs, and surveying and mapping UAVs, etc.

[0039] In terms of weight, civil drones are divided into five categories: micro, light, small, medium, and large. Among them: A micro drone refers to a remotely piloted aircraft with an empty weight of less than 0.25 kg, equipped with the function of altitude or position holding flight, and its design performance simultaneously meets the requirements that the true flight altitude does not exceed 50 m, the maximum level flight speed does not exceed 40 km / h, and the radio transmitting equipment complies with the technical requirements of micro-power short-distance radio transmitting equipment. A light drone refers to a remotely piloted aircraft that simultaneously meets the requirements of an empty weight not exceeding 4 kg, a maximum takeoff weight not exceeding 7 kg, a maximum level flight speed not exceeding 100 km / h, and has the ability to maintain airspace and reliable surveillance capabilities that meet airspace management requirements, but does not include micro drones. A small drone refers to a remotely piloted aircraft or autonomous aircraft with an empty weight not exceeding 15 kg or a maximum takeoff weight not exceeding 25 kg, but does not include micro and light drones. A medium drone refers to a remotely piloted aircraft or autonomous aircraft with a maximum takeoff weight exceeding 25 kg and not exceeding 150 kg, and an empty weight exceeding 15 kg. A large drone refers to a remotely piloted aircraft or autonomous aircraft with a maximum takeoff weight exceeding 150 kg.

[0040] Classified by the activity radius, drones can be divided into ultra-short-range drones, short-range drones, short-distance drones, medium-range drones, and long-range drones. The activity radius of ultra-short-range drones is within 15 km, the activity radius of short-range drones is between 15 and 50 km, the activity radius of short-distance drones is between 50 and 200 km, the activity radius of medium-range drones is between 200 and 800 km, and the activity radius of long-range drones is greater than 800 km.

[0041] Classified by the mission altitude, drones can be divided into ultra-low-altitude drones, low-altitude drones, medium-altitude drones, high-altitude drones, and ultra-high-altitude drones. The mission altitude of ultra-low-altitude drones is generally between 0 and 100 m, the mission altitude of low-altitude drones is generally between 100 and 1000 m, the mission altitude of medium-altitude drones is generally between 1000 and 7000 m, the mission altitude of high-altitude drones is generally between 7000 and 18000 m, and the mission altitude of ultra-high-altitude drones is generally greater than 18000 m.

[0042] Drones are widely used in industries such as police, urban management, agriculture, geology, meteorology, electricity, disaster relief, and video shooting.

[0043] Using a drone integrated with devices such as a high-definition digital camera, a spectral analyzer, and a thermal infrared sensor to fly over farmland to accurately calculate the planting area of the insured plot. The data collected can be used to assess the risk situation and insurance rate of crops and can also determine the loss of damaged farmland. In addition, the drone patrol also realizes the monitoring of crops. Reason for recommendation: Natural disasters occur frequently. In the face of a situation where there is no harvest, agricultural insurance is sometimes a lifeline for farmers, but due to difficult claims settlement, it makes people feel bitter. The application of drones in the field of agricultural insurance can, on the one hand, ensure the accuracy of loss assessment and the high efficiency of claims settlement, and on the other hand, monitor the normal growth of crops, helping farmers take targeted measures to reduce risks and losses.

[0044] A drone equipped with a high-definition digital camera, a camera, and a GPS positioning system can perform autonomous cruise along the power grid, transmit the captured images in real time, and the monitoring personnel can watch and control them synchronously on the computer. Reason for recommendation: Using the traditional manual power line patrol method is arduous and inefficient, and front-line power line inspectors occasionally encounter risks such as "being chased by dogs" and "being bitten by snakes". The drone has realized electronic, information-based, and intelligent inspection, improving the work efficiency, emergency rescue level, and power supply reliability of power line inspection. In emergency situations such as flash floods and earthquakes, the drone can survey and urgently investigate potential dangers of the line, such as the collapse of tower bases, without being affected by the road surface conditions at all. It not only eliminates the pain of climbing the tower but also can survey the visual dead corners of human eyes, which is very helpful for quickly restoring power supply.

[0045] The application of drones in the environmental protection field can be roughly divided into three types. One: Environmental monitoring: Observe the air, soil, vegetation, and water quality conditions, and can also track and monitor the development of sudden environmental pollution incidents in real time and quickly; two, environmental law enforcement: The environmental supervision department uses drones equipped with collection and analysis equipment to cruise in specific areas to monitor the waste gas and wastewater emissions of enterprises and factories and find pollution sources; three, environmental treatment: Use a flexible-wing drone carrying a catalyst and meteorological detection equipment to spray in the air, similar to the working principle of a drone spraying pesticides, to eliminate smog in a certain area. Reason for recommendation: When drones conduct aerial photography, they have strong persistence and can also use modes such as far-infrared night shooting to achieve all-weather aerial monitoring. Drone law enforcement is not restricted by space and terrain. It has strong timeliness, good mobility, and a wide patrol range, enabling law enforcement personnel to quickly detect pollution sources and reducing the pollution degree of smog to a certain extent.

[0046] When the drone is used outdoors, other components such as the drone battery and chip will generate heat according to the usage duration. If the heat of the components cannot be processed in time, on the one hand, it will affect the performance of the drone, and on the other hand, in the case of long-term overheating of the components, the service life will be shortened, affecting the long-term flight of the drone.

[0047] Please refer to Figure 1 shown in the figure. In this embodiment, a system for the persistent flight of an integrated circuit adaptive thermal control drone is provided, including:

[0056] The heat dissipation unit of this embodiment further includes a water-cooled heat dissipation module, and the water-cooled heat dissipation module is used to dissipate heat from the drone chip.

On the other hand, it can automatically adjust the rotation speed of the wing accurately according to the rotation speed of the fan detected by the air-cooling rate detection module for air-cooling heat dissipation. Through the set unmanned aircraft attitude detection module, it can automatically detect the flight inclination of the currently operating unmanned aircraft. When the unmanned aircraft needs to hover, it can automatically adjust each wing of the unmanned aircraft to make the hovering unmanned aircraft more stable.

The battery short-circuit emergency module is used to start the emergency battery when the battery module fails. The set battery short-circuit emergency module is used to supplement emergency power to the unmanned aircraft in time when the battery status detection module detects that the battery is damaged, preventing the operating unmanned aircraft from falling from a high altitude or crashing. The emergency-supplemented power is used for the emergency landing of the unmanned aircraft.

[0060] The signal unit of this embodiment includes a signal sending module and a signal receiving module. The signal sending module is used to send the unmanned aircraft data detected by the detection unit to the user terminal. The signal receiving module is used to receive the control signal sent by the user terminal and transmit it to the control module.
