[0001] The present invention relates to the field of UAV delivery, and particularly to a UAV device and a delivery method for delivering traditional Chinese medicine decoctions. Background Art

[0002] With the wide application of traditional Chinese medicine, the use of traditional Chinese medicine decoctions has become increasingly frequent. However, the traditional delivery method of traditional Chinese medicine decoctions mainly relies on manual delivery, which has many problems: low efficiency, as delivery personnel need to travel back and forth between different locations, especially in traffic congestion, it is difficult to guarantee the delivery time; high cost, as it is necessary to pay the wages of delivery personnel and vehicle maintenance costs, and traffic delays will further increase the operating costs; greatly affected by traffic conditions, traffic congestion is common in cities, increasing the uncertainty of delivery time and affecting the user's medication experience; insufficient safety, as the drugs may be affected by environmental factors such as high temperature and humidity during delivery, resulting in a decline in quality, and traffic accidents may also damage the drugs.

[0003] In recent years, the low-altitude economy has been booming, and UAV technology has been widely applied in many fields such as logistics, medical care, and agriculture. The rise of the low-altitude economy has not only promoted the continuous innovation of UAV technology but also provided new opportunities and challenges for the application of UAVs in the field of traditional Chinese medicine decoction delivery. Delivering traditional Chinese medicine decoctions by UAV can not only improve the delivery efficiency but also reduce the labor cost and reduce the delays caused by traffic congestion. Its advantages are more obvious especially in remote areas and places with inconvenient transportation. In addition, the flexibility of UAVs enables them to quickly respond to emergency needs, providing a strong guarantee for the timely delivery of traditional Chinese medicine decoctions. As a new logistics method, UAV delivery has the advantages of high efficiency, convenience, flexibility, etc., and can effectively solve the deficiencies of traditional delivery methods.

[0004] However, as a special type of drug, the delivery process of traditional Chinese medicine decoctions needs to meet strict safety and hygiene requirements. Most current UAV delivery platforms are designed in a general way and lack targeted design and optimization for the delivery of such special items as traditional Chinese medicine decoctions, and cannot meet the requirements of safe, accurate, and efficient delivery. Combining with the development trend of the low-altitude economy, the present invention solves the deficiencies of traditional delivery methods through specially designed UAVs and receiving platforms, and realizes the safe and efficient delivery of traditional Chinese medicine decoctions. At the same time, the present invention also considers the application requirements of UAVs in different environments, and improves the accuracy and reliability of delivery through intelligent design and optimization, providing new technical support for the modern development of traditional Chinese medicine. Summary of the Invention

[0005] The present invention provides a device and method for delivering traditional Chinese medicine decoctions by drone, aiming to achieve safe, accurate, and efficient delivery of traditional Chinese medicine decoctions. The system includes a safety parachute, a quadcopter drone, an electronic rangefinder, a voice prompt system, a high-strength fiber rope, an automatic unhooking device, a delivery bag, a traditional Chinese medicine liquid encapsulation bottle, and a receiving bracket. The safety parachute can automatically open in case of an emergency to ensure the safe landing of the drone; the electronic rangefinder measures the distance in real time to ensure accurate landing; the voice prompt system sends delivery information to the user to enhance interactivity; the high-strength fiber rope and the automatic unhooking device ensure the stability and automation of the delivery process; the delivery bag is made of waterproof and shockproof materials to protect the safety of the medicine. The receiving bracket can be installed on the roof or the ground, with strong adaptability. The delivery method includes steps such as user ordering, drone takeoff, voice prompt, accurate landing, and automatic unhooking, allowing users to pick up the medicine conveniently.

[0006] For claim 1, a device for delivering traditional Chinese medicine decoctions by drone includes a safety parachute, a quadcopter drone, an electronic rangefinder, a voice prompt system, a high-strength fiber rope, an automatic unhooking device, a delivery bag, a traditional Chinese medicine liquid encapsulation bottle, and a receiving bracket.

[0007] For claim 2, the safety parachute is assembled at the top or key parts of the drone body to ensure rapid deployment in case of an emergency. Its triggering mechanism uses advanced sensor technology to monitor the flight state of the drone in real time, including but not limited to key parameters such as flight altitude, speed, attitude angle, and acceleration. When the drone malfunctions or encounters other emergencies, such as loss of power, loss of control signal, or collision with an obstacle, the sensor will immediately detect the abnormal state and trigger the deployment mechanism of the safety parachute.

[0008] Furthermore, the safety parachute adopts an automatic inflation design and can quickly inflate and deploy when the drone malfunctions. The core advantage of the design lies in its rapid response ability. In case of an emergency, the landing speed of the drone may be relatively fast, and traditional non-inflatable parachutes may not be able to fully deploy in a short time, thus unable to effectively slow down the landing speed. However, the automatic inflation parachute can complete inflation and full deployment in an extremely short time through the built-in high-pressure gas device after the triggering mechanism is activated, ensuring that the parachute can play a role immediately and reducing the landing impact force. The safety parachute is made of high-strength and lightweight materials, such as high-strength nylon fiber or fabric with a Teflon coating, which not only has good tear resistance and abrasion resistance but also can maintain stable performance under harsh weather conditions.

[0009] Regarding claim 3, the quadcopter drone, as the core carrier of the present invention, adopts a quadcopter design and has good stability and maneuverability. Its main structure includes four rotors, a fuselage, a flight control system, and a power system. The four rotors are evenly distributed around the fuselage and can generate sufficient lift and thrust through the motors, enabling the drone to fly stably in the air. The fuselage is made of lightweight and high-strength materials, such as carbon fiber composite materials, which not only ensure the structural strength of the drone but also reduce its own weight and improve flight efficiency.

[0010] Furthermore, the quadcopter drone is equipped with an advanced flight control system that can achieve autonomous flight and precise control. The flight control system includes sensors such as gyroscopes, accelerometers, barometers, and GPS modules, which can real-time monitor the flight state of the drone, such as position, speed, attitude, etc. Based on the data from these sensors, the flight control system can automatically adjust the flight parameters of the drone to ensure its stable flight in various complex environments.

[0011] Regarding claim 4, the electronic rangefinder is assembled at the bottom of the quadcopter drone and can measure the distance between the drone and the receiving platform in real time. Its main function is to provide data support for the precise landing of the drone, ensuring that the drone can accurately place the delivery bag on the receiving platform. By accurately measuring the distance, the electronic rangefinder can help the drone adjust its flight attitude and speed when approaching the receiving platform, achieving a smooth and accurate landing.

[0012] Furthermore, the electronic rangefinder adopts laser ranging technology and can accurately measure the distance between the drone and the receiving bracket. Laser ranging technology has the characteristics of high precision, high stability, and fast response, and can provide reliable measurement data in complex environments. Specifically, the laser rangefinder can achieve centimeter-level measurement accuracy, ensuring that the drone can precisely control the distance during the landing process and avoid collisions or inaccurate deliveries caused by distance errors.

[0013] Even further, regarding claim 5, the voice prompt system is assembled on the drone and is mainly used to send prompt messages to users during the delivery process. The system sends voice prompts to users through the built-in speaker or wireless communication module, such as "Approaching", "Please get ready to receive", etc. These prompt messages can help users understand the delivery progress in a timely manner and make preparations for receiving, thereby improving the interactivity and user experience of the delivery. Its working principle is that the voice prompt system communicates with the user's terminal devices (such as mobile phones, computers, etc.) through the flight control system of the drone. When the drone approaches the receiving position specified by the user, the flight control system will trigger the voice prompt system to send prompts to the user through the preset voice messages. The voice prompt system supports multiple languages and can broadcast according to the user's language preference, further enhancing the user experience.

[0014] Regarding claim 6, the high-strength fiber rope is connected between the lower part of the drone and the automatic decoupling device, mainly used to bear the weight of the delivery bag and ensure the stability and reliability of the delivery process. The two ends of the fiber rope are respectively fixed at the bottom of the drone and the top of the automatic decoupling device, and the high-strength connection points ensure its firmness during flight. Further, the high-strength fiber rope is made of high-performance fiber materials, such as aramid fiber or carbon fiber. These materials have high strength, low weight, good flexibility and corrosion resistance.

[0015] Regarding claim 7, the automatic decoupling device is connected between the lower part of the high-strength fiber rope and the delivery bag, mainly used to automatically decouple under specific conditions to ensure that the delivery bag can be successfully dropped onto the receiving platform. The two ends of the automatic decoupling device are respectively fixed at the bottom of the high-strength fiber rope and the top of the delivery bag, and through an advanced mechanical structure design, its firmness and reliability during flight are ensured. To ensure the reliability and safety of the automatic decoupling device, strict tests and verifications have been carried out in this invention. The tests include multiple decoupling tests, reliability tests, and multiple actual flight tests.

[0016] Further, regarding claim 8, the delivery bag is a key component for loading traditional Chinese medicine decoction encapsulation bottles, and its design fully considers sealing and protection. The delivery bag is made of multi-layer composite materials. The outer layer is a high-strength waterproof material, which can effectively prevent the penetration of rainwater and other external liquids; the inner layer is a soft buffer material, such as bubble film or sponge, which can protect the traditional Chinese medicine decoction encapsulation bottles from being damaged by collision during the delivery process. In addition, the delivery bag also has good air permeability to prevent the traditional Chinese medicine decoction from deteriorating due to long-term sealing.

[0017] Furthermore, the size of the delivery bag is optimized according to the size of the traditional Chinese medicine decoction encapsulation bottles to ensure that it can accommodate two 250ml traditional Chinese medicine decoction encapsulation bottles. The delivery bag is provided with fixing devices inside, such as elastic straps or partition boards, which can fix the encapsulation bottles in the delivery bag to prevent them from being damaged due to shaking during flight. The opening of the delivery bag is designed with a sealed zipper or Velcro to ensure complete sealing during delivery to prevent liquid leakage.

[0018] Regarding claim 9, the receiving bracket is a device for receiving the delivery bag, which can be installed on the roof or on the ground. Its structure is slightly smaller than the current external receiving platform, making it more compact and flexible, and facilitating installation and use in different places. The receiving bracket adopts a modular design and can be quickly assembled and adjusted according to different installation environments. The main structure of the receiving bracket is made of high-strength aluminum alloy material, which has good stability and weather resistance. The receiving bracket is provided with a platform matching the automatic decoupling device. When the delivery bag touches the platform on the receiving bracket, the automatic decoupling device can automatically decouple and accurately drop the delivery bag onto the receiving bracket.

[0019] Regarding claim 10, the method for delivering traditional Chinese medicine decoctions by drone includes the following five steps.

[0020] 1) The user sends a request for delivering traditional Chinese medicine decoctions to the delivery platform through a terminal device (such as a mobile phone, computer, etc.), specifying the delivery address and delivery time. After receiving the user's request, the delivery platform automatically generates a delivery order and sends the order information to the drone delivery system.

[0021] 2) The drone takes off. According to the user's request, the delivery platform arranges for the drone to take off with a delivery bag containing traditional Chinese medicine decoctions. Before taking off, the drone conducts a self-check through the flight control system to ensure that all systems are operating normally. After the drone takes off with the delivery bag, it flies towards the location specified by the user along a preset flight path.

[0022] 3) Prompts and adjustments during flight. During flight, the drone sends prompt messages to the user through the voice prompt system, informing the user of the delivery progress and estimated arrival time. At the same time, the drone measures the distance from the receiving platform in real time through an electronic rangefinder and adjusts its flight attitude and speed to ensure a precise landing. The voice prompt system supports multiple languages and can broadcast according to the user's language preference, further enhancing the user experience.

[0023] 4) Precise landing and automatic unhooking. When the drone reaches the location specified by the user and the delivery bag touches the platform on the receiving bracket, the automatic unhooking device automatically unhooks and drops the delivery bag onto the receiving bracket. The platform mechanism of the receiving bracket confirms the contact of the delivery bag through an induction signal and sends a confirmation signal to the drone to ensure the accurate triggering of the automatic unhooking device. After completing the delivery, the drone automatically returns to the takeoff point to prepare for the next delivery task.

[0024] 5) The user picks up the medicine. After receiving the delivery notice, the user goes to the receiving bracket to pick up the traditional Chinese medicine decoctions, completing the delivery process. The user can confirm receipt through the terminal device and evaluate the delivery service. The delivery platform continuously optimizes the delivery process based on the user's evaluation to improve service quality.

[0025] Through the above design and optimization, the device and method for delivering traditional Chinese medicine decoctions by drone of the present invention can not only ensure the safe and stable delivery of traditional Chinese medicine decoctions, but also improve the interactivity and automation of the delivery, providing a solid technical guarantee for the delivery of traditional Chinese medicine decoctions by drone.

[0026] The above technical solution can achieve the following beneficial effects: Compared with the prior art, the present invention has the following advantages and positive effects: (1).
