Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a pre-hospital emergency unmanned aerial vehicle delivery system. Background Art

[0002] With the rapid development of modern medical technology and the continuous advancement of drone technology, drones are increasingly used in the medical field, especially in the distribution of medical resources for pre-hospital emergency care, where drones have shown great potential and value. With their long-range, load-bearing, and fast flight capabilities, drones provide new solutions for emergency medical rescue, greatly improving rescue efficiency and patient survival rates.

[0003] Traditional medical resource distribution methods, such as ambulance transfer, are often difficult to deliver urgently needed medical resources to patients in the shortest possible time due to factors such as traffic conditions and terrain conditions. Drones can break through these limitations and quickly reach the destination via a straight path in the air, greatly shortening the response time.

[0004] In order to meet the needs of pre-hospital emergency medical resource distribution, drones need to have long-range flight capabilities. This means that drones need to have sufficient endurance and a stable flight control system to ensure that they can complete their missions safely and accurately even in complex weather and terrain conditions. At the same time, drones also need to have a strong load-bearing capacity to carry necessary medical resources such as blood, medicines, and emergency equipment. These resources are often heavy, which places higher demands on the flight performance and load capacity of drones.

[0005] However, when the drone is carrying a large load and flying at a high speed, the change in its center of gravity position has a particularly prominent impact on flight stability and safety. The center of gravity is one of the key factors in the flight stability of a drone, which determines the attitude control and wind resistance of the drone during flight. If the center of gravity position deviates from the preset range, the drone may have problems such as slow control response, reduced stability, and easy rolling during flight, and in severe cases may even cause flight accidents. However, there is relatively little research on the optimization of the center of gravity of drones in the existing technology. Traditional drone designs often focus more on the research and development and optimization of flight control systems, while ignoring the impact of the center of gravity position on the flight performance of drones. Summary of the invention

[0006] The present invention is intended to provide a pre-hospital emergency drone delivery system to solve the technical problem that the prior art lacks an optimized design for the center of gravity position of the drone.

[0007] To achieve the above-mentioned object, the present invention adopts the following technical scheme: a pre-hospital emergency drone delivery system, comprising a drone platform, wherein the drone platform comprises a drone body, a cargo box, a center of gravity detection unit, an inertia detection unit and a center of gravity adjustment strategy unit;

[0008] The cargo box is mounted on the drone body through a gravity center adjustment mechanism, and the gravity center adjustment mechanism includes an X-axis slide rail assembly, a Y-axis slide rail assembly and a rotating platform, which is used to adjust the relative position of the drone body and the cargo box to achieve the adjustment of the overall gravity center position of the drone;

[0009] The center of gravity detection unit is used to detect the overall center of gravity position of the drone when it is in a stationary state; the inertia detection unit is used to detect the change in the center of gravity position of the drone in a flying state; the center of gravity adjustment strategy unit adjusts the position of the cargo box by controlling the center of gravity adjustment mechanism according to the detection results of the center of gravity detection unit and the inertia detection unit, so as to control the center of gravity offset within a preset range.

[0010] The principle and advantage of this solution are: The core of the pre-hospital emergency drone delivery system proposed in the present invention is to ensure that the drone can maintain a stable flight state under various load conditions through an integrated center of gravity management and adjustment mechanism. The system is mainly composed of a drone platform, which integrates the drone body, a cargo box, a center of gravity detection unit, an inertia detection unit and a center of gravity adjustment strategy unit. The cargo box is connected to the drone body through a set of precise center of gravity adjustment mechanisms (including an X-axis slide rail assembly, a Y-axis slide rail assembly and a rotating platform). This design allows the system to dynamically adjust the position of the cargo box according to the load conditions, thereby accurately controlling the overall center of gravity of the drone.

[0011] Before the drone is ready to take off, the center of gravity detection unit will first measure the overall center of gravity position of the drone in a stationary state to prepare basic data for subsequent flights. Once the drone enters the flight state, the inertial detection unit will continue to monitor the changes in the center of gravity position of the drone in flight, and these data will be transmitted to the center of gravity adjustment strategy unit in real time. Based on the preset center of gravity offset range, the strategy unit controls the center of gravity adjustment mechanism to accurately adjust the position of the cargo box to ensure that the center of gravity of the drone always remains within the optimal or safe range.

[0012] By dynamically adjusting the position of the cargo box to accurately control the center of gravity of the drone, the flight instability caused by load changes, such as slow control response, reduced stability and easy rolling, is effectively avoided, significantly improving the safety and reliability of the flight. The coordinated work of the inertial detection unit and the center of gravity adjustment strategy unit can adjust the flight attitude in time according to the center of gravity changes during flight. This not only helps to reduce the energy consumption caused by unnecessary attitude adjustments, but also optimizes energy release by adjusting the center of gravity position during braking, improves braking efficiency and power performance, thereby extending the endurance of the drone, which is particularly suitable for remote medical resource distribution tasks.

[0013] Due to the dynamic optimization of the center of gravity position, the attitude control requirements of the drone during flight are reduced, which reduces the burden on the flight control system, makes the system design more concise and efficient, and also reduces the reliance on high-precision sensors, reducing costs. The system can flexibly respond to the distribution needs of medical resources of different weights and volumes. Even if the items loaded each time are different, the flight stability can be maintained by automatically adjusting the center of gravity position. There is no need to adjust specific flight parameters for each load, which improves the versatility and flexibility of the system. By ensuring the stable flight of the drone under various loads and weather conditions, the present invention can more effectively shorten the response time and quickly deliver urgently needed medical resources to the patient, thereby improving rescue efficiency and patient survival rate.

[0014] Preferably, as an improvement, the center of gravity detection unit is further used to store the position state of the center of gravity adjustment mechanism. When the adjustment of the UAV in the static state is completed, the center of gravity detection unit records the current state position of the adjusted X-axis slide rail assembly, the Y-axis slide rail assembly and the rotating platform as the first center of gravity position;

[0015] When the inertial detection unit detects that the acceleration of the drone is opposite to the direction of travel and the acceleration value is greater than the preset first acceleration threshold, the inertial detection unit will determine that the current drone is in an emergency braking state, and the center of gravity adjustment strategy unit will start the center of gravity adjustment mechanism to move the position of the cargo box backward relative to the direction of travel. When the acceleration is less than the second acceleration threshold, the center of gravity adjustment mechanism will restore the position of the cargo box to the first center of gravity position.

[0016] The beneficial effect of this improvement is that the center of gravity detection unit stores the adjusted center of gravity position (first center of gravity position), so the drone does not need to frequently recalculate and adjust the center of gravity position during flight. This avoids the additional computing load caused by continuous monitoring and adjustment of the center of gravity position, thereby optimizing the flight computing power and enabling the drone to perform flight missions more efficiently. This optimization is particularly important in long-distance flights or complex environments, and can significantly improve the overall performance and endurance of the drone.

[0017] When the drone is in an emergency braking state, due to the heavy load and high speed, the inertia effect is significant, which can easily cause the drone to roll over or lose control. The inertial detection unit monitors the acceleration changes in real time, and quickly activates the center of gravity adjustment mechanism when the emergency braking state is detected, and moves the cargo box backward relative to the driving direction, which can effectively balance the inertial force generated by emergency braking, thereby enhancing the stability of the drone. This design allows the drone to brake smoothly in an emergency, avoiding potential risks caused by loss of control.

[0018] With the help of the center of gravity adjustment mechanism, the drone can adjust its posture more quickly and achieve smooth deceleration when braking suddenly. This shortens the deceleration time of the drone and improves flight efficiency. Especially in time-sensitive scenarios such as emergency rescue, this design enables the drone to reach the target location faster and provide patients with more timely medical assistance.

[0019] Traditional drones often need to rely on powerful flight control systems and braking systems to maintain stability during emergency braking. With the assistance of the center of gravity adjustment mechanism, drones can more easily cope with inertia during emergency braking, thereby reducing the hardware requirements for flight control systems and braking systems. This not only helps reduce the manufacturing cost of drones, but also improves their overall reliability and durability.

[0020] Preferably, as an improvement, during the flight of the UAV, if the inertial detection unit detects that the center of gravity offset of the fuselage exceeds a preset center of gravity range, and the offset time exceeds a preset time threshold, the center of gravity adjustment strategy unit will use the center of gravity adjustment mechanism to adjust the position of the cargo box until the overall center of gravity of the fuselage returns to the preset center of gravity range, and the center of gravity detection unit will update the current state position of the adjusted X-axis slide rail assembly, Y-axis slide rail assembly and rotating platform to a new first center of gravity position.

[0021] The beneficial effect of this improvement is that during the flight of the drone, if the center of gravity of the fuselage deviates beyond the preset range due to factors such as flight power failure, control adjustment error or external interference, and this offset state lasts for a long time, it will seriously threaten the flight safety of the drone. By introducing this improvement, when the inertial detection unit detects this abnormal situation, the center of gravity adjustment strategy unit can quickly start the center of gravity adjustment mechanism and adjust the position of the cargo box, thereby restoring the overall center of gravity of the drone to the preset range. This mechanism effectively enhances the flight safety of the drone and avoids the risk of flight loss of control or crash due to excessive center of gravity offset.

[0022] During the flight of a drone, various sudden failures may occur, such as rotor failure, control system failure, etc. These failures often cause the drone to have an abnormal attitude, which in turn affects its stability and safety. With the assistance of the center of gravity adjustment mechanism, even if the drone encounters a rotor or control system failure during flight, it can restore or stabilize its attitude by adjusting the center of gravity position. This design improves the drone's ability to respond to failures, allowing it to maintain a stable flight state in more complex and harsher environments.

[0023] Traditional UAV flight control strategies mainly rely on the adjustment of the rotor to maintain attitude stability. However, in some extreme cases, such as strong winds, turbulence and other severe weather conditions, the attitude of the UAV may not be fully restored by the adjustment of the rotor alone. By introducing the center of gravity adjustment mechanism, the UAV has more options and flexibility in flight control strategies. When the rotor adjustment cannot fully restore the attitude of the UAV, the center of gravity adjustment mechanism can be started for auxiliary adjustment, thereby optimizing the flight control strategy and improving the overall performance and stability of the UAV. Since the center of gravity adjustment mechanism can replace the adjustment function of the rotor to a certain extent, it can reduce the load and wear of the rotor in some cases. This helps to extend the service life of the rotor and reduce the maintenance cost of the UAV. At the same time, since the design of the center of gravity adjustment mechanism is relatively simple and easy to maintain, it also reduces the maintenance difficulty and cost of the overall system.

[0024] Preferably, as an improvement, the UAV is a multi-rotor UAV, the cargo box is streamlined, and the inner wall of the storage cavity of the cargo box is provided with a fixing belt for bundling items.

[0025] The beneficial effects of this improvement are: the streamlined cargo box design helps reduce air resistance during flight, lowers energy consumption, and improves flight efficiency. At the same time, the fixing belts set on the inner wall of the storage cavity can ensure that the loaded medical supplies will not shift or fall off due to turbulence during flight, ensuring the safety and integrity of the supplies. This design not only improves the flight performance of the drone, but also enhances the reliability of material distribution.

[0026] Preferably, as an improvement, the drone delivery system also includes a ground control center module for drone takeoff, landing, route adjustment, flight monitoring and emergency handling.

[0027] The beneficial effect of this improvement is that the ground control center module provides the drone with comprehensive take-off, landing, route adjustment, flight monitoring and emergency handling functions. This module ensures that the drone can perform tasks safely and accurately according to the preset route, and can respond quickly in emergency situations to ensure the safety of the drone and the smooth completion of the mission. Through the centralized management of the ground control center, the overall efficiency and reliability of the drone delivery system are improved.

[0028] Preferably, as an improvement, the drone delivery system also includes a logistics hub module for loading and unloading of medical supplies, as well as take-off and landing and maintenance of drones.

[0029] The beneficial effect of this improvement is that the logistics hub module facilitates the loading and unloading of medical supplies, and also undertakes the take-off and landing and maintenance tasks of drones. This module ensures that drones can efficiently complete the loading and unloading of supplies, shortening the delivery time and improving the delivery efficiency. At the same time, by centralizing the maintenance and care of drones, the service life of drones is extended and the operating costs are reduced.

[0030] Preferably, as an improvement, the drone delivery system also includes a cloud-based operation control platform module for storage, processing, real-time status monitoring, route optimization and predictive maintenance of drone flight data.

[0031] The beneficial effect of this improvement is that the cloud operation control platform module provides comprehensive data support for the drone delivery system through storage, processing, real-time status monitoring, route optimization and predictive maintenance. This module not only improves the safety and reliability of drone flights, but also improves delivery efficiency through data analysis and optimization. At the same time, the cloud platform also supports remote monitoring and management, providing operators with convenient monitoring methods.

[0032] Preferably, as an improvement, the drone delivery system also includes a communication module for data link communication between the drone and the ground control center, and interface communication between the drone delivery system and the hospital information system.

[0033] The beneficial effects of this improvement are: the communication module ensures the data link communication between the drone and the ground control center, as well as the interface communication between the drone delivery system and the hospital information system. This module realizes the real-time transmission and sharing of information, allowing the drone to perform delivery tasks according to the latest instructions and mission requirements. At the same time, through the interface communication with the hospital information system, the information and intelligent management of medical supplies distribution is realized, and the accuracy and efficiency of distribution are improved.

[0034] Preferably, as an improvement, the center of gravity adjustment mechanism integrates an automatic control algorithm, which can automatically adjust the position of the cargo box according to the data of the center of gravity detection unit, and the center of gravity detection unit and the center of gravity adjustment mechanism realize data sharing and linkage control.

[0035] The beneficial effect of this improvement is that after the center of gravity adjustment mechanism is integrated with the automatic control algorithm, it can automatically adjust the position of the cargo box according to the data of the center of gravity detection unit, realizing data sharing and linkage control. This improvement not only improves the accuracy and efficiency of center of gravity adjustment, but also reduces the complexity and error rate of manual operation. Through the optimization of the automatic control algorithm, the UAV can maintain a stable center of gravity position under various loads and flight conditions, improving the safety and stability of flight.

[0037] Figure 2 4 is a system flow chart of an embodiment of the present invention. DETAILED DESCRIPTION

[0038] The following is further described in detail through specific implementation methods:

[0039] Example

[0040] Basically as attached Figure 1 and attached Figure 2 As shown, a pre-hospital emergency drone delivery system includes: a drone platform, a ground control center module, a logistics hub module, a cloud operation control platform module and a communication module.

[0041] The UAV platform includes a UAV, a cargo box, a flight control system, a center of gravity detection unit, an inertial detection unit and a center of gravity adjustment strategy unit.

[0042] The drone itself is responsible for carrying cargo, while the flight control system ensures that the drone can fly stably according to the preset route. The drone is a multi-rotor drone with stable flight performance, appropriate load capacity and reliable navigation system. It achieves precise positioning and autonomous navigation through built-in sensors and flight control algorithms. The drone is built with high-performance motors and lightweight materials to reduce weight and improve flight efficiency; the flight control system integrates flight control algorithms and redundant designs to ensure flight safety.

[0043] The cargo box is used to carry medical supplies. The cargo box is installed on the drone body through a center of gravity adjustment mechanism. The center of gravity adjustment mechanism is used to adjust the relative position of the drone body and the cargo box, thereby achieving the overall center of gravity position adjustment of the drone and the cargo box. The cargo box is streamlined, and the inner wall of the storage cavity of the cargo box is provided with a fixing belt for bundling items, so that medicines, equipment, etc. are fixed in the cargo box to avoid collisions between medicines and equipment in the cargo box during the flight of the drone, and to prevent items from hitting the cargo box and affecting the flight posture of the drone.

[0044] The center of gravity adjustment mechanism includes an X-axis slide rail assembly, a Y-axis slide rail assembly and a rotating platform. The X-axis slide rail assembly and the Y-axis slide rail assembly are used to provide the cargo box with X and Y directions of movement in the horizontal plane, and the rotating platform enables the cargo box to rotate around the vertical axis. The vertical axis is located at the center of the drone body, and the X-axis slide rail assembly and the Y-axis slide rail assembly are installed on the rotating platform.

[0045] Specifically, the X-axis slide rail assembly and the Y-axis slide rail assembly are mainly composed of slide rails, sliders, drive motors, transmission mechanisms (such as gear belts or lead screws), limit switches and position sensors. The slide rail is a linear guide rail, usually made of high-strength, low-friction materials to ensure smooth and stable movement. The slider is installed on the slide rail and can move linearly along the slide rail. The drive motor is connected to the slider through a transmission mechanism (such as a synchronous belt or precision lead screw), providing precise power to the slider to move it on the slide rail.

[0046] A connecting plate or bracket is usually installed on the slider of the X-axis slide assembly, and the connecting plate is fixedly connected to the bottom of the cargo box by bolts or other fasteners to ensure that the cargo box can move with the movement of the slider of the X-axis slide assembly. On the slider of the X-axis slide assembly, there will be an additional mounting surface or bracket for mounting the slide rail of the Y-axis slide assembly. The slider of the Y-axis slide is then connected to the connecting plate of the cargo box, so that the cargo box can be adjusted to any position in the plane through dual sliding of the X-axis and Y-axis. The base of the Y-axis slide assembly is fixedly installed on the slider of the X-axis slide assembly, forming a nested structure, so that the cargo box can move independently and flexibly in both the X-axis and Y-axis directions.

[0047] The rotating platform is mainly composed of a turntable, a rotary bearing, a drive motor, a reducer (such as a planetary reducer), an encoder and a controller. The turntable is the main component that carries the X-axis slide assembly (and the cargo box on it), and is usually made of high-strength and lightweight materials. The rotary bearing is located between the turntable and the fixed bracket, allowing the turntable to rotate smoothly. The drive motor is connected to the turntable through the reducer to provide the torque required for rotation. The encoder is used to monitor the angular position of the turntable to ensure precise control. The base of the X-axis slide assembly (including the slide and motor, etc.) is directly mounted on the turntable of the rotating platform, so that the entire X-axis slide assembly and the cargo box on it can rotate with the turntable. The fixed part of the rotating platform (usually the frame supporting the turntable and the drive system) is fixedly connected to the center position of the drone body through a sturdy bracket or connector to ensure that the center of rotation coincides with the center of the drone body, which is conducive to the adjustment and optimization of the overall center of gravity.

[0048] By controlling the motor to drive the cargo box to move on the slide rail and the rotating platform to rotate, the position of the cargo box can be adjusted to optimize the overall center of gravity of the drone. The slide rail assembly and the rotating platform use high-precision transmission mechanisms and sensors to ensure the accuracy and stability of position adjustment; the center of gravity adjustment mechanism integrates an automatic control algorithm to automatically adjust the position of the cargo box according to the data of the center of gravity detection unit.

[0049] The center of gravity detection unit is designed to detect the overall center of gravity position of the drone when it is stationary on land. This unit is implemented through a built-in pressure sensor group, which is installed on the landing gear of the drone in a non-linear manner. The sensor group can accurately measure the pressure on each point of the landing gear of the drone after loading the items, and then calculate the position of the overall center of gravity through an algorithm.

[0050] The center of gravity adjustment unit calculates the required center of gravity adjustment according to the instructions of the center of gravity detection unit, and controls the motors of the X-axis slide rail assembly, the Y-axis slide rail assembly and the rotating platform to adjust the center of gravity. During the adjustment process, the center of gravity detection unit continuously feeds back the current data to ensure that the final center of gravity position coincides with the geometric center point. This adjustment mechanism can avoid frequent changes in the overall center of gravity of the drone due to different loading items each time.

[0051] The center of gravity detection unit also has a memory function, which can remember the adjusted position of the cargo box. This is achieved through a storage chip or cloud storage technology, and the current state position of the adjusted X-axis slide rail assembly, Y-axis slide rail assembly and rotating platform is recorded as the first center of gravity position. The unit realizes data sharing and linkage control with the flight control system and the center of gravity adjustment mechanism to ensure that the drone reaches the best center of gravity configuration before takeoff.

[0052] The inertial detection unit is used to detect the change in the center of gravity position of the drone during flight. The unit monitors the attitude and acceleration of the drone in real time through built-in sensors such as accelerometers and gyroscopes, thereby determining the flight status of the drone. When it is detected that the acceleration is opposite to the driving direction and the acceleration value is greater than the preset first acceleration threshold, the inertial detection unit will determine that the current drone is in an emergency braking state and trigger the center of gravity adjustment strategy unit to take corresponding adjustment measures.

[0053] The center of gravity adjustment strategy unit adjusts the position of the cargo box by controlling the center of gravity adjustment mechanism according to the detection result of the inertia detection unit to control the center of gravity offset within a preset range. In the case of emergency braking, the unit will activate the center of gravity adjustment mechanism to move the position of the cargo box backward relative to the driving direction, etc., to reduce the center of gravity offset. When the acceleration drops, that is, less than the second acceleration threshold, the center of gravity adjustment mechanism restores the position of the cargo box to the first center of gravity position.

[0054] During the stable flight of the drone, if the center of gravity of the fuselage is detected to be offset beyond the preset center of gravity range, and the offset time exceeds the preset time threshold, it means that there is a problem with the flight of the drone and it cannot maintain stability. At this time, the center of gravity adjustment strategy unit will use the center of gravity adjustment mechanism to adjust the position of the cargo box until the entire fuselage returns to a stable state. After adjustment, the current state position of the X-axis slide rail assembly, the Y-axis slide rail assembly and the rotating platform will be updated to the new first center of gravity position.
