Technical Field

[0001] This application relates to the field of pre-hospital emergency care technology, and in particular to a pre-hospital emergency care system based on unmanned aerial vehicles and an intelligent emergency care platform, and its application method. Background Technology

[0002] Pre-hospital emergency care is a crucial link in saving lives, and its response speed and on-site treatment capabilities directly affect patient survival rates. Traditional pre-hospital emergency care models heavily rely on ambulances and accompanying medical personnel. However, in traffic congestion, remote areas, or complex terrain, ambulances often struggle to reach the scene promptly. Even when they do arrive, their equipment may be ineffective due to chaotic environments and the lack of operational experience among first responders (usually non-medical professionals). Therefore, optimization and improvement of pre-hospital emergency care methods are necessary.

[0003] Among related technologies, the use of drones to transport emergency medical supplies for pre-hospital emergency care is becoming increasingly common, and this method can shorten pre-hospital emergency response time to some extent.

[0019] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0020] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 This is a schematic diagram of the structure of a pre-hospital emergency care system based on a drone and an intelligent emergency rescue platform, as proposed in an embodiment of this application. Figure 2This is a schematic diagram of the structure of a drone carrier module proposed in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of an intelligent emergency rescue platform module proposed in an embodiment of this application; Figure 4 This is a schematic diagram of the structure of an embedded parking bay module proposed in an embodiment of this application; Figure 5 This is a flowchart illustrating an application method for a pre-hospital emergency care system based on a drone and an intelligent emergency care platform, as proposed in an embodiment of this application. Detailed Implementation

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0022] It should be noted that the solutions for transporting emergency medical supplies via drones for pre-hospital emergency care in the relevant embodiments have the following drawbacks: First, the functionality is relatively limited, generally only able to deliver a single device, such as an automated external defibrillator (AED), failing to provide a comprehensive emergency support environment and struggling to cope with complex and diverse emergency scenarios (such as cardiac arrest accompanied by respiratory distress, requiring vital sign monitoring, etc.). Second, the human-machine interaction is poor; the delivered equipment lacks guidance design for non-professional users, and first responders may not be able to use the equipment quickly and correctly under stress, leading to low emergency response efficiency or even misoperation. Third, the system integration is low; the drones, emergency medical equipment, and the ambulances are isolated, lacking system-level coordination, scheduling, and retrieval mechanisms. The mission ends once the drone completes delivery, failing to form a closed-loop process of "response-treatment-transfer." Fourth, the scenario adaptability is weak; the emergency medical equipment platform does not consider the transformation between transportation and use, potentially resulting in bulky and inconvenient transport, or rudimentary functionality that cannot effectively support emergency care.

[0023] To address this, this application proposes a pre-hospital emergency medical system and its application method based on drones and an intelligent emergency medical platform, providing a complete pre-hospital emergency medical solution integrating rapid response, comprehensive emergency care, intelligent guidance, and system collaboration. This application overcomes traffic barriers, enabling rapid response and delivery of emergency supplies and equipment. It also provides an integrated, multi-functional on-site emergency medical platform to handle various injuries, not just single-device delivery. Furthermore, its design significantly lowers the operational threshold of the equipment, guiding first responders without professional backgrounds to perform emergency procedures smoothly and correctly, improving the margin for error. It also achieves efficient collaboration, automatic recovery, and energy replenishment among drones, the emergency medical platform, and ambulances, forming a sustainable closed-loop system, rather than just one-time delivery. Finally, its modular and foldable design resolves the conflict between convenient transportation and complete on-site functionality of emergency medical equipment.

[0024] The following description, with reference to the accompanying drawings, describes a pre-hospital emergency care system based on unmanned aerial vehicles (UAVs) and an intelligent emergency care platform, and its application method.

[0025] Figure 1 This is a schematic diagram of the structure of a pre-hospital emergency care system based on a drone and an intelligent emergency rescue platform, as proposed in an embodiment of this application. Figure 1 As shown, the system includes: a drone transport module 100, an intelligent emergency rescue platform module 200, and an embedded landing bay module 300.

[0026] Among them, the drone transport module 100 is used to respond to pre-hospital emergency care instructions, take off from the top of the ambulance, grab the intelligent emergency care platform module 200 and transport the intelligent emergency care platform module 200 to the emergency site, and return to the embedded landing cabin module 300 after completing the pre-hospital emergency care task.

[0027] The intelligent emergency rescue platform module 200 has a folded state and an unfolded state. After arriving at the emergency scene, the intelligent emergency rescue platform 200 is used to switch from the folded state to the unfolded state, providing various types of emergency rescue equipment and guiding the first witness to use the emergency rescue equipment to perform emergency rescue operations on the patient.

[0028] The embedded parking bay module 300 is integrated on the top of the ambulance for parking, charging, maintenance and redeployment of the drone transport module 100.

[0029] Specifically, this application constructs a modular pre-hospital emergency care system that deeply integrates hardware, software, and processes. It features a modular and collaborative system architecture, comprising a three-in-one pre-hospital emergency care equipment system consisting of a drone transport module 100, an intelligent emergency platform module 200, and an embedded landing bay module 300. In some scenarios, the modules can be structurally relatively independent, but in others, they can maintain continuous information interconnection through standardized mechanical interfaces (e.g., the grasping structure in the drone transport module 100 and the docking interface in the embedded landing bay module 300) and wireless communication links.

[0030] As one possible implementation, the core commands of the pre-hospital emergency care system in this application can be issued by the dispatch equipment of the emergency center, including mission initiation commands, flight path parameters, and mission update information, and received and executed by the UAV transport module 100. During the mission, the intelligent emergency platform module 200 monitors key data such as the patient's vital signs and emergency operation status, and transmits the real-time monitoring data back to the emergency center through its communication unit, enabling medical personnel to remotely observe and make emergency decisions. The determination of mission completion is also issued by the emergency center, or by the intelligent emergency platform module 200 reporting the mission completion status based on situational signals such as medical personnel taking over, after which the dispatch system confirms and issues a return command. The above three modules have a clear division of labor in their physical structure and achieve a closed-loop communication mechanism of "mission scheduling—path control—vital sign monitoring—status reporting" at the information level, forming a complete emergency care system from rapid deployment and on-site rescue to equipment recovery and replenishment, overcoming the fragmented problems of traditional pre-hospital emergency care equipment in terms of dispatch, coordination, and information sharing.

[0031] In one embodiment of this application, the drone transport module includes: a drone fuselage, rotors, a visual recognition component, a retractable transport structure, a landing component, and a grasping structure. The drone fuselage includes a flight control system, a communication module, and a power supply. The communication module is used for data interaction with a remote emergency medical center dispatch system. The visual recognition component includes multiple high-definition cameras arranged in different directions. The visual recognition component is used to identify markings on the embedded landing bay module, the grasping position of the intelligent emergency medical platform module, and the landing environment at the emergency medical scene.

[0032] Specifically, such as Figure 2 As shown, the structure of the UAV transport module 100 includes the UAV fuselage (101), rotor (102), visual recognition component (103), retractable transport structure (104), landing component (105) and grasping structure (106).

[0033] The UAV fuselage (101) features a forward-leaning streamlined design, combining smooth lines and a folded structure, and houses the flight control system, communication module, and power supply. The fuselage's shape enhances the device's user-friendliness and operational safety through rounded corners and a simple outline.

[0034] The visual recognition component (103) includes high-resolution cameras facing downwards and forwards respectively, and integrates low-light environment imaging enhancement function to identify the markings on the embedded landing bay module 300, the grab point of the intelligent emergency rescue platform module 200 and the on-site landing environment, and assist in flight direction adjustment and landing point selection.

[0035] In one embodiment of this application, a telescopic transport structure is used to extend and retract to accommodate the rescue supplies to be grabbed, thereby providing operating space for the grabbing structure; the landing component includes multiple legs, which are made of a cushioned flexible material and the bottom of the legs is made of a friction-enhancing material; the grabbing structure includes multiple sets of gripping devices, each set of gripping devices including multiple adjustable grippers, and the grabbing structure is used to adjust the gripping parameters of the grippers for the rescue supplies to be grabbed.

[0036] Specifically, continue to refer to Figure 2 For example, the retractable transport structure (104) is located at the lower part of the fuselage, and its function is independent of the grabbing structure (106) responsible for grabbing the intelligent emergency rescue platform module 200 and other materials. The retractable structure provides adjustable operating space for the grabbing structure (106) according to mission requirements. Through a multi-stage telescopic and folding mechanism, the retractable transport structure is compact when folded, allowing the grabbing structure (106) to efficiently grab small materials in a small space; when unfolded, the outer dimensions increase, providing sufficient operating margin for the grabbing structure (106) to handle large or wide materials. Visual markings and limit buckles are provided at the structural connection points to facilitate the operator's confirmation of the current telescopic status and reduce the risk of misoperation.

[0037] For example, in practical applications, when transporting small emergency supplies, the retractable transport structure (104) remains in a retracted form to reserve concentrated and adequate grabbing space; while when transporting large supplies, the structure can expand outward, allowing the grabbing structure (106) to have a larger operating range to successfully complete grabbing and securing. The shape change of the retractable transport structure is only used to provide grabbing space and does not directly participate in the carrying of supplies.

[0038] The landing assembly (105) includes four outriggers with cushioned flexible material. The bottom of the outriggers is made of friction-enhancing material to adapt to uneven ground conditions such as grass and slopes, ensuring landing stability.

[0039] The gripping structure (106) includes two sets of clamping devices, each set having two rotatable and adjustable grippers, which can flexibly adjust the grip size according to the shape of the stretcher or materials. The inside of the grippers is provided with anti-slip material, and the current gripping status is indicated by visual color blocks and light feedback.

[0040] As one possible implementation, the UAV carrier module 100 features a silver, bright red, and black color scheme. The silver casing enhances the device's visibility and recognizability, the black supporting components convey a sense of stability, and the red highlights the camera components and key operational nodes. The top and front of the module are equipped with lighting indicators that display corresponding light signals under different operating conditions.

[0041] This module supports vertical take-off and landing, adapts to diverse urban spatial conditions, and enables non-professional users to complete the operation process smoothly through clear visual cues and feedback.

[0042] Therefore, the UAV carrier module 100 in this embodiment of the application achieves highly reliable automated connection between modules based on a visual recognition-based automatic grasping and precise docking mechanism. The UAV carrier module (100), through the collaboration of its visual recognition component (103) and grasping structure (106), can accurately identify and grasp the folded intelligent emergency rescue platform module 200. Similarly, the UAV and the embedded landing bay module 300 achieve automatic landing, locking, and energy replenishment through the cooperation of positioning markers (303a) and docking charging interface (304). This mechanism ensures that the system can operate efficiently and reliably with no or minimal intervention.

[0043] In one embodiment of this application, the intelligent emergency rescue platform module includes: a platform main frame, a support area, an equipment functional area, retractable components, and folding joints. The platform main frame, in its unfolded state, is a platform with a two-sided enclosed structure to create a wraparound rescue space. The support area includes a chest region, a head-surrounding region, and two side functional surrounds, serving to support the patient and the equipment functional areas. Various types of emergency rescue equipment are correspondingly arranged in different areas of the support area within the equipment functional area. Specifically, the equipment functional area integrates cardiopulmonary resuscitation (CPR) equipment, monitoring and retrieval equipment, and life support equipment. The CPR equipment is located in the chest region, the monitoring and retrieval equipment is located in the side functional surrounds, and the life support equipment is located in the head-surrounding region.

[0044] Specifically, the intelligent emergency rescue platform module 200 is the core unit of the system's on-site emergency rescue. This module adopts a foldable design, is transported by drones, and unfolds on-site, enabling a crucial shift from "air transport" to "ground rescue." Figure 3As shown, the module structure consists of: a platform main frame (201), a support area (202), an equipment functional area (203), a retractable component (204), and a folding joint (205).

[0045] The main frame of the platform (201) is made of lightweight composite material. When folded, it is compact and lightweight, making it easy to transport. When unfolded, it forms a platform with enclosed structures on both sides, creating a wraparound rescue space. Its appearance adopts a low-profile, rounded corner design with edges that taper inward to create a wraparound visual effect. The color scheme is based on white, dark gray, and matte black, with bright red accents in key operating areas.

[0046] The support area (202) is located in the center of the platform and is used to fully support the patient's head and body, providing a core support area for emergency operations. This area uses a flexible support material to improve the patient's fit and stability during the rescue process.

[0047] The equipment functional areas (203) are arranged around the sides of the support area (202) and the outer side of the head, adopting a two-layer layout of "core support area - functional surrounding area". Among them, the support area (202) as a whole serves as the core support area, used to place the patient; cardiopulmonary resuscitation related devices (203b) are placed in the corresponding position on the chest, and related life support devices (203c) are placed in the area above the head. The areas on both sides of the support area (202) constitute the functional surrounding area, used to place monitoring and retrieval devices (203a). Through the above area division, different types of emergency equipment are distributed according to their functional attributes in the chest area, the area above the head, and the functional surrounding areas on both sides of the core support area, thereby achieving equipment integration, clear operation path, and continuity of task flow.

[0048] In one embodiment of this application, monitoring and access devices include electrocardiogram monitoring and automated external defibrillator (AED) units, cardiopulmonary resuscitation (CPR) devices include band-type CPR assist devices, and life support devices include oxygen support units. Each type of emergency equipment is labeled with corresponding high-contrast colors and graphic symbols.

[0049] Specifically, in this embodiment, the monitoring and access device (203a) can be an electrocardiogram monitoring and AED unit. This unit is located in the accessible device area on both sides of the platform, adopts a unified control and shared display method, and is equipped with an embedded storage structure for electrode pads and sensors, which facilitates rapid deployment in the emergency rescue process.

[0050] The cardiopulmonary resuscitation-related device (203b) can be a band-type cardiopulmonary resuscitation (CPR) assistive device, which is set in the support area (202) above the patient's chest and performs rhythmic compressions through a flexible band and an automatic compression component to meet the requirements for stability and continuity of cardiopulmonary resuscitation during rescue.

[0051] The life support device (203c) can be an oxygen support unit located in the support area (202) above the patient's head, including an embedded oxygen mask (equipped with a flexible fixation strap and quick-connect structure) and a separately set oxygen cylinder connected by a retractable tubing, for providing continuous oxygen support.

[0052] In this embodiment, the operation areas of each device are clearly marked with high-contrast colors and graphic symbols to improve device recognizability and enhance the operational intuition and efficiency for first witnesses or non-professionals.

[0053] In one embodiment of this application, retractable components are arranged on both sides of the main frame of the platform. The retractable components include slide rails and locking structures. The retractable components are used to adjust the length of the intelligent emergency platform module according to the patient's height. Folding joints are arranged at the skeleton connection position of the main frame of the platform. The folding joints are used to switch the state of the intelligent emergency platform module.

[0054] Specifically, continue to refer to Figure 3 For example, the retractable component (204) is integrated into the side frames of the platform. The side frames are equipped with hidden slide rails and locking structures, which can adjust the effective length of the platform according to the patient's height to achieve stable support for the head and torso area. Through length adjustment, the retractable component (204) maintains the rationality and fit of the support position in the usage scenarios of patients of different body types, effectively improving the comfort and safety during the transfer process, reducing secondary risks such as slippage and bumps that may be caused by differences in body size, and is suitable for a diverse range of people.

[0055] The folding joint (205) is located at a key connection point of the platform frame and is formed by a combination of lightweight composite materials and joint connection structure, enabling the platform to quickly switch between folded and unfolded states. In the folded state, the platform has a compact overall volume, making it easy to carry, store, and fit in confined spaces; in the unfolded state, it maintains the required load-bearing capacity and structural stability. Users can unfold and fold the platform according to preset visual cues and simplified structural operation gestures. The operation logic follows the steps from seeing to understanding to completion, meeting the needs of non-professional users for rapid deployment and low psychological stress in emergency situations.

[0056] Therefore, the intelligent emergency rescue platform module 200 in this embodiment is a flexible and highly integrated intelligent emergency rescue platform. This module adopts a foldable design, enabling conversion between a "compact transport form" and a "fully functional unfolded form." It employs a patient-centered "core carrying area—functional surrounding area" layout, highly integrating key emergency rescue functions such as ECG monitoring (203a), CPR assistance (203b), oxygen support (203c), and AED into a portable platform. High-contrast color zoning and graphical labels provide strong visual guidance, significantly reducing the operational threshold and risk of misoperation for non-professional users. The platform's operation guidance relies on a triple mechanism: highlighted red key area labels, illustrative operation graphics and text prompts on the screen, and synchronized voice prompts. This enables first responders to quickly locate key operating points, understand operating steps, and complete the rescue process in emergency situations.

[0057] In one embodiment of this application, the embedded landing bay module includes: a bay body, a lifting mechanism, a landing platform, and a docking and charging interface; wherein, the bay body is embedded in the top of an ambulance, and the bay body includes status indicator lights for displaying the working mode of the UAV carrier module; the lifting mechanism is used to control the landing platform to lift and lower according to the working status of the UAV carrier module.

[0058] Specifically, the parking module embedded in the ambulance in this application is the rear support unit of the system, such as... Figure 4 As shown, the module's structure includes: a cabin (301), a lifting mechanism (302), a parking platform (303), and a docking and charging interface (304).

[0059] The cabin (301) features an embedded design that blends seamlessly with the ambulance roof profile, maintaining the vehicle's overall integrity. The surface material is predominantly matte dark gray, complemented by high-brightness functional indicator lights. Status indicator lights (301a) are provided to convey operational modes such as standby, takeoff / landing, and charging via a lighting system.

[0060] The lifting mechanism (302) is an electric lifting mechanism that can control the vertical lifting of the parking platform (303). When the equipment is in use, the platform is raised to ensure the take-off and landing space for the UAV, and when not in use, the platform is lowered to complete the equipment storage.

[0061] In one embodiment of this application, the landing platform is a symmetrical dual-wing platform in its deployed state. The dual-wing platform serves as the parking area for the UAV carrier module. The landing platform includes positioning markings, a docking structure, and a high-contrast warning area. The docking and charging interfaces are arranged on the landing platform and are used to fix and charge the UAV carrier module after landing.

[0062] Specifically, continue to refer to Figure 4For example, the landing platform (303) adopts a symmetrical double-wing platform design, which forms a stable landing area for the UAV after unfolding. The platform surface is equipped with high-contrast positioning marks (303a) and docking structures, and high-contrast warning zones are set at the edge of the platform to guide the attitude and angle of the UAV during landing.

[0063] The docking and charging interface (304) is located on the parking platform (303) and includes a docking structure and a charging interface to realize physical fixation and automatic power replenishment of the UAV after landing.

[0064] In summary, the pre-hospital emergency care system based on drones and an intelligent emergency platform in this application embodiment improves the efficiency of emergency response and treatment. The drone module, through air transport, can avoid some ground traffic obstacles and shorten the delivery time of emergency supplies. The intelligent emergency platform module integrates multiple emergency functions, enabling patients to receive comprehensive life support on-site, reducing equipment preparation and switching time. The system also reduces the operational difficulty for non-professional users by transforming the emergency process into operable steps through functional zoning, graphical signage, and a multimodal guidance system. This allows first responders without professional training to perform initial rescue based on system prompts, reducing the possibility of operational errors and improving the feasibility of rescue. Furthermore, the system improves operational continuity and stability. Its modular architecture ensures the independence of each functional unit, while automatic grabbing, docking, and charging mechanisms achieve effective connection and energy replenishment between modules, forming a continuously operating system. The intelligent emergency platform's design for accompanying patient transport maintains the continuity of monitoring and treatment, reducing risks during transport. Furthermore, the system is highly identifiable and collaborative. The visible design of the drone's status lights and landing bay provides visual cues to the surrounding crowd, which helps maintain order at the scene. By clearly defining the task assignments of different rescue roles, it provides basic support for multi-role collaborative rescue.

[0065] To more clearly illustrate the specific implementation process of the pre-hospital emergency care system based on drones and an intelligent emergency rescue platform in practical applications, a pre-hospital emergency care method proposed in an embodiment of this application will be described in detail below. This method is applied to the pre-hospital emergency care system based on drones and an intelligent emergency rescue platform in the above embodiments, that is, to perform relevant control on the system in the above embodiments to implement the method of this embodiment. The various devices involved in this method are as described in the above embodiments and will not be repeated here.

[0066] Figure 5 This is a flowchart illustrating an application method for a pre-hospital emergency care system based on a drone and an intelligent emergency rescue platform, as proposed in an embodiment of this application. Figure 5 As shown, the method includes the following steps: Step S101: In response to receiving a pre-hospital emergency care request, a start command is sent to the UAV carrier module and the embedded landing bay module to control the UAV carrier module to take off based on the positioning marks in the embedded landing bay module.

[0067] Specifically, this step involves mission activation and drone takeoff. In one embodiment of this application, controlling the drone carrier module to complete takeoff based on the positioning markers in the embedded landing bay module includes: reading the positioning markers through a visual recognition component on the drone carrier module, wherein the positioning markers are used to provide position calibration information for the drone carrier module; and performing attitude positioning and altitude maintenance of the drone carrier module before takeoff based on the positioning markers.

[0068] For example, after receiving a dispatch command, the ambulance's embedded landing module (300) activates its lifting mechanism (302) to raise the landing platform (303) to a predetermined height on the roof. The UAV carrier module (100) powers on and performs a self-test, and the visual recognition component (103) reads the positioning markings (303a) on the landing platform (303). These markings provide the UAV with visual references for hovering and position calibration, enabling it to more efficiently and accurately complete attitude positioning and altitude maintenance before takeoff. After completing positioning, the UAV takes off autonomously.

[0069] Step S102: After the drone transport module grabs the intelligent emergency rescue platform module and transports it to the emergency scene, the intelligent emergency rescue platform module is controlled to switch to the deployed state to support the patient.

[0070] Specifically, this step begins with platform retrieval and aerial transport. Before the drone takes off, the intelligent emergency medical platform module 200 is retrieved from the emergency medical facility by medical personnel and placed in the designated retrieval area, remaining folded for drone docking. After the drone flies above the intelligent emergency medical platform module 200, its visual recognition component (103) locks onto the retrieval mark on the platform, enabling the retrieval structure (106) to perform precise retrieval and fixation. After retrieval is completed, the drone (100), carrying the platform module (200), flies to the emergency scene along the planned flight path.

[0071] Further, the drone performs on-site landing and platform release. After arriving at the scene, the drone assesses the environment using the visual recognition component (103), selects a flat area, and lands smoothly using the landing component (105). The gripping structure (106) unlocks the drone and releases the intelligent emergency rescue platform module (200).

[0072] Furthermore, the platform is deployed and the patient is placed. The first witness manually operates the folding joint (205) of the intelligent emergency rescue platform module 200, converting it from a folded state to an deployed state. After deployment, the platform forms a stable emergency rescue space. The patient is placed in the central support area (202).

[0073] Step S103: Using the identification and prompt information on the intelligent emergency rescue platform module, guide the first witness at the emergency scene to use the various types of emergency rescue equipment integrated in the intelligent emergency rescue platform to perform emergency operations on the patient until the patient is transferred to an ambulance.

[0074] Specifically, this step begins with first aid guidance and execution. The first responder, based on the clear, high-contrast graphic labels and / or voice prompts on the device's functional area (203), operates the integrated ECG monitoring (203a), CPR assist device (203b), and oxygen support (203c) devices in sequence to provide initial first aid to the patient.

[0075] Furthermore, professional handover and joint transfer are carried out. After the ambulance and medical personnel arrive at the scene, the grabbing structures on both sides of the intelligent emergency platform module (200) facilitate manual picking up by medical personnel, smoothly transferring the patient along with the platform into the ambulance, achieving a seamless connection and avoiding secondary injury. The platform can continue to provide vital sign monitoring support inside the vehicle.

[0076] Step S104: After completing the current pre-hospital emergency care mission, control the drone transport module to return to the embedded landing bay module.

[0077] Specifically, this step involves the drone's return and autonomous recovery. After medical personnel arrive at the scene and take over the patient transfer, the landing module 300 or the remote emergency system will send a mission completion command to the drone transport module 100. Alternatively, the drone transport module 100 can also determine that the current mission has ended based on the emergency process status information. Upon receiving the mission completion status, the drone transport module 100 initiates the return procedure and autonomously returns to the location of the ambulance. Its visual recognition component (103) re-identifies the markings on the landing platform (303) to achieve precise positioning and landing. After landing, the docking and charging interface (304) of the landing module (300) automatically connects to the drone, completing locking, power supply, and standby preparation, ready for the next mission.

[0078] In summary, the application method of the pre-hospital emergency care system based on drones and intelligent emergency rescue platform in this application embodiment can quickly respond to pre-hospital emergency care tasks, complete the rapid delivery of emergency supplies and multifunctional on-site emergency care, and improve the timeliness, intelligence and reliability of pre-hospital emergency care.
