Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicle (UAV) ground auxiliary equipment, and particularly to an intelligent takeoff and landing platform for UAVs based on state recognition, which is applicable to the safe takeoff and landing of UAVs under complex terrains, multi-module collaborative control, and operation guarantee. Background Art

[0002] With the rapid development of UAV technology, its applications in wild scenarios such as forest fire prevention and control, ecological monitoring, terrain mapping, and emergency rescue are becoming increasingly widespread. Especially in the early monitoring of forest fires and the acquisition of fire field data, UAVs have high mobility and real-time transmission capabilities and have become one of the important equipment for forest fire prevention and control. However, at the forest fire prevention and control site, the operating environment of UAVs is often extremely complex, with uneven forest land terrain, numerous surface obstacles, and drastic changes in wind speed and thermal airflow. Due to limited site conditions, some small and medium-sized multi-rotor UAVs usually adopt the methods of hand-held takeoff and hand-held recovery to complete takeoff and landing when performing tasks. This operation method has obvious safety hazards, and the operators are extremely vulnerable to rotor injuries.

[0003] To improve the safety of field operations, some UAV ground auxiliary equipment has emerged at present, such as portable takeoff and landing platforms, heat dissipation and charging bases, etc. However, these devices have obvious defects: single function, only focusing on single requirements such as heat dissipation, charging, or position return, lacking systematic intelligent control capabilities; insufficient communication guarantee, severe attenuation of communication signals in scenarios such as forest areas and mountains, and existing platforms do not integrate signal relay functions, resulting in data loss or signal interruption easily occurring in the edge area of UAV operations, affecting the timeliness of tasks; inefficient energy management, unable to sense the operating state of UAVs, and all modules still maintain full operation after the UAV lands, causing energy waste and equipment overheating, and the heat dissipation device continues to work ineffectively after takeoff, increasing the system burden, which limits their practical applications in wild scenarios such as forest fire prevention and control.

[0004] In summary, the existing UAV ground auxiliary equipment has significant deficiencies in terms of adaptability to complex terrains, operation safety, communication stability, and energy management. There is an urgent need for an intelligent takeoff and landing platform with state recognition and multi-module collaborative control capabilities. Summary of the Invention

[0005] Aiming at the defects of the existing technology, the present invention provides an intelligent takeoff and landing platform for UAVs based on state recognition, which realizes horizontal stable support under complex terrains, automatic recognition of UAV takeoff and landing states, and multi-module intelligent linkage control, solves the problems of single function, low energy efficiency, unstable communication, and unsafe operation of existing equipment, and provides a safe, efficient, and intelligent comprehensive solution for wild UAV operations. The technical solution of the present invention is as follows:

[0006] A state recognition-based intelligent take-off and landing platform for unmanned aerial vehicles (UAVs) is characterized by comprising a support platform, a heat dissipation module, a pressure sensing module, an environmental monitoring module, a power management module, a signal relay module, and an intelligent collaborative control module.

[0007] Furthermore, the load-bearing platform is made of carbon fiber composite material and includes a platform panel, platform side panels, platform base plate, platform columns, and support legs. The platform panel and platform side panels are connected by hydraulically damped planar hinges. The platform side panels can be folded up to be flush with the platform panel to increase the take-off and landing area. After folding, they are fixed by side panel diagonal braces. One end of the side panel diagonal brace is inserted into a reserved hole to ensure structural stability. The platform side panels and platform base plate are connected by a snap-lock.

[0008] Furthermore, the support legs are hinged to the flat base plate, and each support leg is equipped with a telescopic joint controller, which can independently adjust the length to allow the platform to adapt to uneven terrain and maintain a level position; the support legs adopt a foldable design and can be folded and fitted onto the flat base plate after operation.

[0009] Furthermore, the heat dissipation module is installed on the back of the platform panel and includes at least one fan with its air outlet facing upwards, allowing airflow to pass through the perforated channels of the platform panel to dissipate heat from the drone.

[0010] Furthermore, the pressure sensing modules are spaced out along the length and width of the platform panel surface, covering the preset area for UAV take-off and landing.

[0011] Furthermore, the platform panel, platform base plate, and platform columns form a frame structure. The platform panel and platform base plate maintain a certain height to form an equipment compartment. The environmental monitoring module, power management module, signal relay module, and intelligent collaborative control module are integrated and installed on the platform base plate to avoid damage to the equipment from the outdoor environment.

[0012] Furthermore, the signal relay module integrates signal amplification and is connected to an antenna to enhance the communication signal between the UAV and the ground terminal.

[0013] Furthermore, the environmental monitoring module is used to collect environmental parameters such as temperature, humidity, and wind speed, and supports data storage in built-in or external storage devices.

[0014] Furthermore, the power management module works in conjunction with the intelligent collaborative control module to achieve independent power supply, energy consumption monitoring, and power allocation for each module of the system, thereby optimizing overall energy efficiency.

[0015] Furthermore, the intelligent collaborative control module is an embedded microprocessor equipped with a signal acquisition circuit, a drive circuit and a communication interface. It is electrically connected to the pressure sensing module (3), the heat dissipation module (2), the environmental monitoring module (4), the signal relay module (6) and the power management module (5). It intelligently outputs control commands according to the take-off and landing status of the UAV and switches the working modes of each module.

[0016] The control logic method of the intelligent collaborative control module includes the following steps:

[0017] When the pressure sensing module detects a pressure value, it determines that the drone has landed; the intelligent collaborative control module activates the heat dissipation module and shuts down the signal relay module and the environmental monitoring module, and the platform enters the heat dissipation mode.

[0018] When the pressure signal is released, it is determined that the drone has taken off; the intelligent collaborative control module shuts down the heat dissipation module and restarts the signal relay module and environmental monitoring module, and the platform enters the communication enhancement and environmental monitoring mode.

[0019] Through the above control logic, the automatic identification of the take-off and landing status of the UAV and the coordinated control of multiple modules can be realized, thereby achieving the goals of energy saving and intelligent management.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Intelligent status recognition and linkage control: The pressure sensing module automatically identifies the take-off and landing status of the drone and controls the start and stop of the heat dissipation module, signal relay module and environmental monitoring module to achieve automatic coordination and energy optimization management among the modules.

[0022] Enhanced environmental monitoring and data collaboration: The environmental monitoring module integrated in this invention can operate synchronously when the UAV takes off, collecting environmental parameters such as ground temperature, humidity and wind speed in real time. It complements the UAV's onboard sensors, improving the continuity and reliability of data in scenarios such as forest fire monitoring and meteorological assessment.

[0023] With improved energy efficiency and safety, the platform retains only its heat dissipation function after the drone lands, stopping the operation of other modules and reducing unnecessary power consumption; at the same time, it reduces the risk of rotor contact, enabling unmanned and safe operation.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this invention.

[0028] like Figure 1 and Figure 2 As shown, the present invention provides a state recognition-based intelligent take-off and landing platform for unmanned aerial vehicles. In a preferred embodiment, it mainly includes a carrying platform (1), a heat dissipation module (2), a pressure sensing module (3), an environmental monitoring module (4), a power management module (5), a signal relay module (6), and an intelligent collaborative control module (7).

[0029] The supporting platform (1) is made of carbon fiber composite material and includes a platform panel (100), a platform side panel (101), a platform base plate (102), support legs (103), and platform columns (106). The platform panel (100) and the platform side panel (101) are connected by a hydraulically damped planar hinge (108), allowing the side panel (101) to be folded outward until it is on the same horizontal plane as the platform panel (100), thereby effectively expanding the take-off and landing area of ​​the UAV. The folded platform side panel (101) is reinforced by a side panel brace (104), one end of which is placed in a pre-reserved hole (109) to ensure stability under load and wind load. The platform side panel (101) and the platform base plate (102) are connected by a snap-lock (107) for easy deployment and storage.

[0030] The support leg (103) is hinged to the platform base plate (102). Each support leg (103) is equipped with a telescopic joint controller (105), which allows the operator to independently adjust the length of each support leg, so that the platform can quickly adapt to uneven terrain such as mountains and forests and always maintain the level of the bearing surface; after the operation is completed, the support leg (103) can be folded inward, which greatly reduces the storage volume of the entire platform.

[0031] The platform panel (100) is designed with a regular hollow structure. The pressure sensing module (3) is arranged on the upper surface of the platform panel (100) to detect the pressure on the panel in real time. The heat dissipation module (2) is installed on the back of the platform panel (100) and includes at least one fan with the fan outlet facing upward. When working, the airflow can penetrate the hollow structure of the panel and directly force-cool the UAV battery and power system after landing.

[0032] The platform base plate (102), platform panel (100), and platform column (106) form a frame structure that maintains a certain height, creating a protected equipment compartment. On the platform base plate (102), an environmental monitoring module (4), a power management module (5), a signal relay module (6), and an intelligent collaborative control module (7) are centrally installed.

[0033] The environmental monitoring module (4) integrates temperature sensors, humidity sensors, and wind speed sensors to collect external environmental parameters. The collected data can be stored in the built-in memory or an external storage device to meet the needs of long-term, large-capacity data recording.

[0034] The signal relay module (6) integrates a signal amplification circuit and is connected to an external antenna (8). This module is used to receive and amplify the image transmission and telemetry signals transmitted by the UAV, while enhancing the control command signals transmitted from the ground, effectively extending the reliable communication range of the UAV in complex terrain.

[0035] The power management module (5) is used to provide stable power to the various functional modules of the platform. This module works in conjunction with the intelligent collaborative control module (7), receiving its instructions and executing the power supply switching and power distribution for each module.

[0036] The intelligent collaborative control module (7) is an embedded microprocessor equipped with a signal acquisition circuit, a drive circuit, and a communication interface. This module is electrically connected to the pressure sensing module (3), the heat dissipation module (2), the environmental monitoring module (4), the signal relay module (6), and the power management module (5).

[0037] The basic working principle and intelligent control process of this invention are as follows:

[0038] In the initial state, before the UAV lands on the platform, the pressure sensing module (3) does not detect any pressure signal. At this time, the intelligent collaborative control module (7) controls the heat dissipation module (2) to be in the off state, while keeping the signal relay module (6) and the environmental monitoring module (4) in normal working mode, and the platform fully guarantees the communication and environmental monitoring tasks of the UAV.

[0039] When the drone lands on the platform panel (100), the pressure sensing module (3) detects a pressure signal. Based on this, the intelligent collaborative control module (7) determines that the drone has landed and then issues a control command: activate the heat dissipation module (2) to cool down the drone; and at the same time shut down the signal relay module (6) and the environmental monitoring module (4).

[0040] When the drone takes off again and leaves the platform panel (100), the pressure signal detected by the pressure sensing module (3) is released. The intelligent collaborative control module (7) immediately determines that the drone has taken off and issues a new control command: shut down the heat dissipation module (2), and at the same time restart the signal relay module (6) and the environmental monitoring module (4) to restore the communication enhancement and environmental data acquisition functions.

[0041] Through the above-mentioned automatic control logic based on state recognition, the present invention realizes intelligent coordination and on-demand start-stop of various functional modules, which significantly improves the system's energy efficiency management level and the degree of intelligence in task execution.

[0042] To further illustrate the intelligence and application flexibility of this invention, the control logic of this invention will be further described below in conjunction with two typical field operation scenarios. The intelligent collaborative control module (7) can preset multiple working modes according to actual operation needs, and operators can switch between them themselves, so that the functional combination of the platform is highly matched with the specific task requirements.

[0043] Example 1: Full-function operation mode applied to wildfire monitoring

[0044] In this embodiment, the platform is deployed at the front line of forest fire prevention to perform long-term, large-scale fire monitoring and data collection tasks. The operator sets the system to "full-function monitoring mode".

[0045] Once the drone takes off, the pressure sensing module (3) releases its signal. The intelligent collaborative control module (7) not only executes the basic "post-takeoff" instructions, but also, based on the current mission mode, forces the environmental monitoring module (4) and the signal relay module (6) to operate at full power. The environmental monitoring module (4) continuously collects temperature, humidity, wind speed, and wind direction data from the surrounding ground, forming an air-to-ground complementarity with the drone's onboard data, providing a complete and continuous data chain for fire situation assessment.

[0046] When the UAV landing platform exports data or undergoes emergency cooling, the pressure sensing module (3) is triggered. The intelligent collaborative control module (7) activates the heat dissipation module (2) and simultaneously shuts down the environmental monitoring module (4) and the signal relay module (6).

[0047] Example 2: Communication Enhancement Mode Applied to Water Search and Rescue Missions

[0048] In this embodiment, the platform is used to support water search and rescue or patrol missions in the field of security law enforcement. It has extremely high requirements for the stability of the communication link and the system's battery life, but there is no explicit requirement for recording environmental meteorological data. The operator sets the platform to "communication enhancement mode".

[0049] Once the drone takes off, the intelligent collaborative control module (7) executes differentiated control according to the preset mode: it immediately activates the signal relay module (6) to ensure communication quality along the long river; at the same time, it keeps the control environment monitoring module (4) off. This saves the module's power consumption, concentrates power on communication support, and extends the platform's continuous operation time in the field.

[0050] When the drone lands, the pressure sensing module (3) is triggered. The control module activates the heat dissipation module (2) to ensure that the drone can quickly take off again, while keeping the signal relay module (6) off, so that the platform enters a standby state with the lowest power consumption, which reflects the ultimate energy efficiency management strategy under specific tasks.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
