Modular drone take-off and landing platform adapted for logistics parks Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a modular UAV take-off and landing platform adapted for logistics parks. Background Technology

[0002] With the intelligent development of the logistics industry, drone delivery has become an important method for last-mile delivery in logistics parks, breaking through the limitations of ground transportation and improving delivery efficiency. In logistics park scenarios, drone delivery is characterized by high frequency, multiple suppliers, and multiple sizes and models, requiring take-off and landing platforms to have good adaptability, efficiency, and environmental adaptability.

[0003] However, existing drone take-off and landing platforms have many shortcomings in actual use, making it difficult to meet the actual needs of logistics parks:

[0004] Poor adaptability: Existing platforms are mostly designed with a single size and can only be adapted to specific models of drones. This means that when logistics parks introduce drones from multiple suppliers for delivery, they need to deploy multiple models of take-off and landing platforms, which greatly increases infrastructure costs and space occupation.

[0005] Lack of system linkage: The existing platform has not established an effective linkage with the logistics park management system, and cannot provide real-time feedback on the storage status of drones and the working status of equipment, which is not conducive to the overall scheduling of logistics distribution;

[0006] Insufficient environmental adaptability: Logistics parks have complex environmental factors such as dust, wind and rain, uneven ground, and wind speed changes. The existing platform has weak protection performance, which can easily lead to a decrease in the take-off and landing accuracy of drones, equipment damage, and affect delivery efficiency and operational safety.

[0007] Therefore, developing a modular take-off and landing platform that can adapt to drones of various sizes, integrate with logistics park management systems, and has good environmental adaptability is key to solving the current pain points of drone delivery in logistics parks. Summary of the Invention

[0008] The purpose of this invention is to provide a modular drone take-off and landing platform adapted to logistics parks, so as to solve the problems of poor adaptability, lack of system linkage, insufficient environmental adaptability and low operation efficiency of drone take-off and landing platforms in logistics parks.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a modular drone take-off and landing platform adapted to logistics parks, comprising:

[0010] The storage module and the landing guidance module are located on top of the storage module;

[0011] The storage module has multiple sealed storage spaces for storing logistics drones, and each sealed storage space is equipped with an infrared position sensor to detect whether the drone is in place and to send a feedback signal.

[0012] The storage module is equipped with a communication module for transmitting data and an environmental sensing unit for detecting the environment within the logistics park.

[0013] The landing guidance module includes a visual recognition image and a lighting component. The visual recognition image is a bullseye pattern, and different sizes of bullseye patterns correspond to different models of logistics drones. The visual recognition image provides the drone with an image for identification and provides guidance for the drone's landing. At the same time, the lighting component displays the status information of the storage module, environmental parameter information, and take-off and landing information through changes in the light.

[0014] Preferably, the storage module includes multiple frames, encapsulation plates, and electrically movable doors. A connecting lock plate is provided between adjacent frames to lock adjacent frames. The frames are rectangular frame structures. The encapsulation plates are fixedly connected to the top, bottom, and both ends of the frames, and the electrically movable doors are movably connected to the front and rear ends of the frames, so that multiple sealed storage spaces are formed between the frames, encapsulation plates, and electrically movable doors. The purpose of parking and retrieving the drone is achieved by opening and closing the frames.

[0015] Preferably, the lighting assembly includes multiple marker lights and status lights. The visual recognition image is printed on the top center of the encapsulation board using a primer, silkscreen, varnish, and daisy pattern process. The marker lights are fixedly installed on both sides of the top of the encapsulation board, and the status lights are fixedly connected to the center of the top of the encapsulation board.

[0016] Preferably, it also includes an electrical box located at the bottom of the encapsulation board. The electrical box contains a circuit breaker, a fuse, a switching power supply, and a remote control module. The circuit breaker and fuse are used to provide circuit overload protection, and the switching power supply is used to provide stable power to the marker lights, status lights, electric sliding door panels, communication module, and environmental sensing unit. The remote control module is used to communicate with the communication module.

[0017] Preferably, the circuit breaker is connected to the first end of the fuse via a live wire, the second end of the fuse is connected to the live wire terminal block of the switching power supply, and the circuit breaker is connected to the neutral wire terminal block of the switching power supply via a neutral wire.

[0018] Preferably, the environmental sensing unit includes a wind speed sensor, a visibility sensor, and a light sensor, used to detect wind speed, visibility, and light intensity within the logistics park.

[0019] Preferably, each of the four corners of the frame is fixedly connected with a foot cup, which extends through and to the bottom of the encapsulation plate. The foot cup is a vacuum adsorption structure with height adjustment function, used to adapt to uneven ground in the logistics park and prevent the lifting platform from sliding.

[0020] Preferably, each of the four corners of the top of the encapsulation plate is fixedly connected with a lifting ring.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention covers the types of mainstream logistics drone sizes by visually recognizing different types of images. Each type of visually recognized image corresponds to a logistics drone. Combined with a modular splicing storage frame, it enables precise guidance and orderly storage of drones from multiple suppliers. It eliminates the need to deploy multiple models of take-off and landing platforms, reducing the infrastructure costs and space occupation of logistics parks. Through a communication module, it establishes two-way communication with the logistics park management system, enabling functions such as drone take-off and landing reservation, status monitoring, and remote control. This facilitates the overall scheduling of logistics parks and improves delivery efficiency.

[0023] 2. This invention also uses an environmental sensing unit to detect wind speed, visibility, and light intensity in the park in real time, dynamically adjust the working status of the lighting components, and send early warning signals. The sealed dustproof design of the electric movable door panel and the anti-slip structure of the foot cups enable the lifting platform to adapt to the complex environment of the logistics park and improve operational safety. The frame is spliced ​​by connecting locking plates, and the number of frames can be flexibly increased or decreased according to the delivery volume of the logistics park to adapt to the needs of logistics parks of different sizes. Installation and maintenance are convenient. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please refer to Figures 1-4. The present invention provides a technical solution: a modular drone take-off and landing platform adapted to logistics parks, including a storage module 1, a landing guidance module 2, an electrical box 12, a foot cup 17, a hanging ring 5, a communication module 6, and an environmental sensing unit 7. The landing guidance module 2 is fixed to the top of the storage module 1, the electrical box 12, the communication module 6, and the environmental sensing unit 7 are integrated on the storage module 1, the foot cup 17 is fixed to the bottom of the storage module 1, and the hanging ring 5 is fixed to the top of the storage module 1.

[0033] The storage module 1 includes four interconnected frames 8, a sealing plate 9, and four electrically movable door panels 10. Adjacent frames 8 are fixedly connected by connecting lock plates 11. The connecting lock plates 11 are made of stainless steel and are fastened to the frames 8 with bolts to ensure the structural stability after splicing. The number of frames 8 can be flexibly increased or decreased according to the delivery volume of the logistics park through the connecting lock plates 11, so as to realize modular expansion.

[0034] The encapsulation plate 9 and the electric movable door plate 10 work together to form 4 independent sealed frame spaces, with only one side left open. Each open side corresponds to one electric movable door plate 10. The size of the frame space is designed according to the size of mainstream logistics drones and can be adapted to small, medium, large and special logistics drones respectively.

[0035] The frame 8 is made of 6061 aluminum alloy with a wall thickness of 3mm. The inner wall is covered with a 3mm thick EVA buffer and anti-collision layer to prevent damage to the drone during storage. Each frame 8 corresponds to an independent frame space for storing logistics drones of different sizes. The electric movable door 10 is driven by a 42HS40 stepper motor. The edge of the door is equipped with EPDM sealing strips, and the inner side is equipped with a 100-mesh dust filter to effectively block dust from entering. It is suitable for harsh environments such as dust and wind and rain in logistics parks. The purpose of parking and retrieving the drone is achieved by opening and closing the electric movable door 10.

[0036] The landing guidance module 2 includes four visual recognition images 3 and a lighting component 4, wherein the lighting component 4 includes two outline lights 41 and two status lights 42;

[0037] The visual recognition image 3 is a bullseye pattern. Different sizes of bullseye patterns correspond to different models of logistics drones. The four visual recognition images 3 are printed on the top center of the storage module 1 to reduce sunlight reflection and ensure the recognition accuracy of the drone under strong light. The process of "primer, screen printing, clear varnish and chrysanthemum pattern" is adopted. The primer is gray anti-rust paint, the screen printing pattern is a bullseye pattern of different sizes, the clear varnish is wear-resistant transparent paint, and the chrysanthemum pattern structure can reduce the reflectivity under strong light. Each visual recognition image 3 is used to guide the corresponding size of logistics delivery drone to land. The visual recognition images 3 cover the standard sizes of mainstream logistics drone manufacturers, realizing seamless adaptation of drones from multiple suppliers.

[0038] Two outline lights 41 are fixed on the top sides of the storage module 1 respectively. Each outline light 41 is composed of three strip lights connected end to end. The strip light model is LED-5050, rated voltage 24V, power 10W, and is connected to the electrical box 12 with a waterproof plug. The protection level reaches IP65. It is used to mark the outline of the take-off and landing platform and illuminate the visual recognition image 3. Its brightness is adaptively adjusted according to the light intensity detected by the environmental perception unit 7 to ensure the recognition accuracy of the UAV in low light environment.

[0039] Two status lights 42 are fixed to the top center of the storage module 1, facilitating all-around observation by logistics park staff. The status lights 42 are tri-color LED warning lights used to display the working status of the take-off and landing platform. Their color switching is linked to the drone take-off and landing process and the instructions of the logistics park management system. The model is LTE-5071, with a rated voltage of 24V. The luminous intensity of each of the three colors is ≥8000mcd. Yellow indicates that the drone has entered the take-off and landing stage, reminding staff to stay away from the safe area; red indicates that the drone is taking off and landing, and personnel are prohibited from entering; green indicates that take-off and landing is complete, and staff can carry out operations. Their color switching is linked to the drone take-off and landing process and the instructions of the logistics park management system.

[0040] The electrical box 12 is made of cold-rolled steel plate with an IP54 protection rating. Internally, it includes a circuit breaker 13, a fuse 14, a switching power supply 15, and a remote control module 16. The circuit breaker 13 is connected to the first terminal of the fuse 14 via a live wire. The second terminal of the fuse 14 is connected to the live wire terminal block of the switching power supply 15. The circuit breaker 13 is also connected to the neutral wire terminal block of the switching power supply 15 via a neutral wire. The circuit breaker 13 is model DZ47-63C16 with a rated current of 16A, used to connect and disconnect 220V mains power and provide overload protection. The fuse 14 is equipped with a 10A fuse, model RT18-32, which melts in the event of high voltage or short circuit, protecting subsequent circuits. Electrical components: The switching power supply 15 is model RS-150-24, with an input voltage of AC110-240V, an output voltage of DC24V, and an output current of 6.5A. It provides stable power to the marker lights 41, status lights 42, electric movable door panel 10, communication module 6, and environmental sensing unit 7. The remote control module 16 is model ESP32, which has WiFi and Bluetooth communication functions. It communicates with the communication module 6 through a UART interface with a baud rate set to 9600bps to ensure the accuracy of command transmission. The remote control module 16 communicates with the communication module 6 to receive commands from the logistics park management system and control the start and stop of various components in the electrical box 12.

[0041] The communication module 6 uses a 4G module (model: EC200S), which supports TD-LTE and FDD-LTE dual modes. It establishes a TCP / IP connection with the logistics park management system to realize bidirectional data transmission. The data includes drone take-off and landing reservation, storage status query, equipment fault alarm and remote parameter configuration functions. It provides real-time feedback on the drone storage status and take-off and landing platform working status, which is convenient for the logistics park to carry out overall scheduling. The communication latency is ≤100ms.

[0042] The environmental perception unit 7 includes a wind speed sensor (model: FC-28), a visibility sensor (model: PMS5003), and a light sensor (model: BH1750), used to detect wind speed, visibility, and light intensity within the logistics park, and output detection signals to the landing guidance module 2 and the communication module 6. The wind speed sensor has a measurement range of 0-30 m / s and an accuracy of ±0.3 m / s; the visibility sensor has a measurement range of 10-10000 m and an accuracy of ±5%; the wind speed sensor is used to detect the real-time wind speed within the logistics park. When the wind speed exceeds a preset threshold, the communication module 6 sends a no-fly warning signal to the logistics park management system, and the status light 42 displays the warning color to prevent the drone from taking off and landing in severe weather; the light sensor has a measurement range of 0-65535 lux and an accuracy of ±2%. All three communicate with the remote control module 16 via an I2C interface, with a data update frequency of 1 Hz.

[0043] The environmental sensing unit 7 has preset wind speed thresholds of 6 m / s, visibility thresholds of 500 m, and light intensity thresholds of 200 lux. When the detected parameters exceed the thresholds, the corresponding adjustment commands or warning signals are triggered in a timely manner.

[0044] There are 16 foot cups 17, which are fixed to the four corners of the bottom of the four frames 8. They are adjustable-height vacuum adsorption foot cups, used to adapt to uneven ground in the logistics park and prevent the lifting platform from sliding. The model is JB-100, the adjustment range is 50-100mm, the diameter of the vacuum adsorption plate is 100mm, and the adsorption force is ≥500N, ensuring the stability of the lifting platform on uneven ground. There are 4 lifting rings 5, which are fixed to the four corners of the top of the storage module 1. They are made of stainless steel, model M20, and have a rated load of 500kg. They can be connected to the fixed steel structure of the logistics park through 8mm diameter steel wire ropes to enhance the lifting platform's resistance to typhoons and strong winds.

[0045] Working principle:

[0046] Reservation and Preparation Phase: Based on the delivery task plan, the logistics park management system receives and sends drone take-off and landing reservation instructions to the take-off and landing platform through the communication module 6. The instructions include the drone model, delivery time, and target frame space number. The environmental perception unit 7 monitors the wind speed, visibility, and light intensity in the park in real time. The remote control module 16 analyzes the detection data. If the wind speed is ≤6m / s, visibility is ≥500m, and light intensity meets the recognition requirements, it is determined that the take-off and landing conditions are met. The communication module 6 sends a take-off and landing signal back to the management system. At the same time, the remote control module 16 controls the status light 42 to display yellow to remind the staff.

[0047] Landing guidance phase: After receiving the landing command from the management system, the UAV flies to the location of the take-off and landing platform through its own positioning module; when the environmental perception unit 7 detects that the light intensity is ≥200 lux, the UAV directly identifies the visual recognition image 3 corresponding to the top of the storage module 1 through the visual recognition module to accurately locate the landing position; when the light intensity is ≤200 lux, the remote control module 16 controls the marker light 41 to turn on, and automatically adjusts the brightness according to the light intensity, with an adjustment range of 300-1000 lm, to ensure that the visual recognition image 3 is clearly visible, and the UAV achieves accurate landing through the visual recognition image 3.

[0048] Automatic storage phase: After the drone lands in the designated area on top of the storage module 1, it sends a landing confirmation signal to the take-off and landing platform via the wireless communication module. After receiving the signal, the remote control module 16 controls the electric movable door 10 of the corresponding frame space to open, with an opening time of ≤3s. The drone detects the environment in the frame space through its own obstacle avoidance module and flies into the frame space after confirming that there are no obstacles. When the drone triggers the infrared position sensor (model: E18-D80NK) in the frame space, the infrared position sensor sends a position signal to the remote control module 16. The remote control module 16 controls the electric movable door 10 to close, with a closing time of ≤3s. At the same time, the communication module 6 sends a signal to the management system that the drone has been successfully stored, and the status light 42 turns green.

[0049] Takeoff process stage: According to the delivery requirements, the management system sends a drone takeoff command to the takeoff and landing platform through the communication module 6. The command includes the frame space number where the target drone is located. After receiving the command, the remote control module 16 controls the electric movable door 10 of the corresponding frame space to open, and the status light 42 displays yellow. The staff takes out the drone and places it in the takeoff area on top of the storage module 1. The drone completes the positioning calibration through the visual recognition image 3 and then takes off. After the drone takes off, it sends a takeoff completion signal to the takeoff and landing platform through wireless communication. The remote control module 16 controls the electric movable door 10 to close, and the status light 42 switches to green.

[0050] Anomaly Handling Phase: If the environmental sensing unit 7 detects a wind speed > 6 m / s, the remote control module 16 immediately sends a no-fly warning signal to the management system via the communication module 6. At the same time, the status light 42 displays orange. Upon receiving the warning, the management system suspends the take-off and landing of the relevant drones. If the equipment malfunctions (such as the electric movable door panel 10 failing to open properly, or the marker light 41 malfunctioning), the remote control module 16 identifies the fault type through its built-in fault detection algorithm and sends a fault alarm signal to the management system via the communication module 6. The status light 42 flashes red, and the fault log is stored for subsequent troubleshooting and maintenance by staff.

[0051] The take-off and landing platform in this embodiment is adapted to the multi-model, high-frequency delivery needs of logistics parks. It achieves flexible expansion through modular design, and its linkage with the logistics park management system enhances the overall scheduling capability of delivery. Environmental perception and protection design enhance operational safety, and it can be widely used in last-mile delivery scenarios in various logistics parks.
