Currently, existing drone launch technologies are inefficient, unable to launch continuously, and drones cannot take off quickly, limiting their rapid response capabilities. Furthermore, they generally have limited applicability and are highly restricted, only suitable for specific drones and specific locations, failing to achieve adaptive and rapid adjustments to meet the requirements of drone launch conditions. In addition, existing drone launch technologies involve multiple complex operations, lacking intelligence and automation, increasing operational complexity and labor costs. Summary of the Invention

[0004] The purpose of this invention is to address the problems of low launch efficiency, inability to launch continuously, and significant limitations of existing UAV launch technologies by providing a belt-type magnetically adjustable UAV launch device, parameter adjustment, and launch method.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A belt-driven, magnetically adjustable unmanned aerial vehicle (UAV) launcher includes an adjustable belt launch assembly and an intelligent integrated management platform. The adjustable belt launch assembly includes a multi-dimensional control module, multiple modular adapters, an adjustable launch belt track, and a modular adapter recovery module. The adjustable belt launch assembly is equipped with casters at its bottom and support feet.

[0007] The multi-dimensional control module includes a basic device frame, a transmission-type rotating chassis, and a height and angle adjustment mechanism. The transmission-type rotating chassis is used to adjust the lateral angle of the adjustable belt-launching assembly. The height and angle adjustment mechanism includes first and second telescopic support arm assemblies, used to adjust the height of the bottom device of the basic device frame and the tilt angle of the adjustable launch belt track. The adjustable launch belt track is mounted in the basic device frame for launching the UAV. The adjustable launch belt track consists of a multi-functional layered belt chain, a belt running device, a belt telescopic module, a launch status monitor, and a UAV lifting mechanism. An electromagnetic brake can also be installed for emergency braking. The multi-functional layered belt chain is driven and installed in the basic device frame. It features multiple layers, with an electromagnetic adsorption unit installed on the belt, containing an electromagnetic adsorption unit that can magnetically attract segmented adapters for accelerating the UAV during launch. The belt telescopic module includes front and rear telescopic arm assemblies and a moving mechanism for adjusting the belt length. The launch status monitor is used to determine whether the launch process is operating normally. The UAV lifting mechanism carries the UAV and segmented adapters in the early stage of launch, and descends after the designated electromagnetic adsorption unit is activated so that the UAV and segmented adapters are attracted by the electromagnetic adsorption unit. The segmented adapter has probes and a support part for fixing the UAV and releasing the UAV during launch to complete the launch. The segmented adapter recovery module includes an adapter transport track and an adapter detector for recovering the segmented adapters.

[0008] The intelligent integrated management platform includes an information processing system, an equipment management system, and a human-machine interaction system. The information processing system is used to read and process UAV information and summarize launch and equipment data. The equipment management system is used to issue instructions to manage the adjustable belt launch assembly. The human-machine interaction system is connected to the display screen on the adjustable belt launch assembly for operator processing.

[0009] Optionally, the height and angle adjustment structure includes a first telescopic support arm group and a second telescopic support arm group. The telescopic support arm is connected to the belt shaft and cooperates with the belt telescopic module included in the adjustable launch belt track to complete the adjustment of the height of the bottom device and the tilt angle of the adjustable launch belt track.

[0010] The multi-functional layered belt chain is divided into three layers within the basic frame of the device: the top layer is the launch belt segment, the middle layer is the buffer belt segment, and the bottom layer is the adapter recovery belt segment. The launch belt segment retains 20% of its capacity as an emergency buffer zone for UAV launch.

[0011] The front and rear telescopic arm assemblies in the belt telescopic module are used to provide sufficient horizontal length when adjusting the belt length, and the moving mechanism is responsible for reducing the length of the middle buffer belt section to meet the requirements of device height, launching belt section inclination angle and length.

[0012] The moving mechanism moves by relying on the motor to drive the gear and rack path to mesh, so that the moving mechanism can move precisely. The transverse push rod connects the support arms at both ends. The upper end of the support arm assembly has a small belt shaft, which is responsible for pressing the belt to engage with the belt drive half pulley, ensuring the stability of the belt assembly. The belt drive half pulley also has a wireless charging device inside and outside.

[0013] Optionally, the multifunctional layered belt chain is composed of multiple belts spliced ​​together. The multifunctional layered belt structure is divided into upper and lower parts. The main body of the lower part is a special-shaped belt with an inverted trapezoidal shape. The upper layer of the special-shaped belt has embedded woven sensors to detect the state of the belt during the drone delivery process to reflect the degree of completion of the delivery process. The upper part is an electromagnetic adsorber, which is powered by a wireless charging device in the belt shaft. The electromagnetic adsorber is used to adsorb the modular adapter connected to the drone.

[0014] Optionally, the modular adapter consists of multiple base plates with flexible filler between them, allowing the adapter to bend via a belt. A drone release arm and a rear support structure are mounted on top of the base plates of the modular adapter. The rear support structure includes a support column and a probe located inside it, symmetrically installed on both sides of the tail base plate among the multiple base plates of the modular adapter. The probe can extend to connect with the drone. The drone release arm, located on the center line, is mounted on the front end of the head base plate among the multiple base plates of the modular adapter via a pivot. Torsion springs are provided on both sides of the drone release arm shaft to allow the drone release arm to maintain a forward tilting tendency, and its base is located inside the head base plate, locked to the head base plate by electromagnetic adsorption. A bearing part is provided on the upper part to control the fixing and release of the drone by electromagnetic adsorption.

[0015] Optionally, the segmented adapter recycling module is located inside the bottom of the basic frame of the device, including an adapter transport track and an adapter detector. The adapter transport track is composed of belts and is connected to the segmented adapter transfer station. The width of the adapter transport track is equal to the distance between the support columns in the rear support structure of the segmented adapter. The height of the adapter transport track above the ground is greater than the height of the rear support structure, and the distance between the adapter transport track and the adapter recycling belt section is slightly greater than the height of the bottom plate of the segmented adapter. The adapter detector is responsible for identifying the segmented adapter and sending a signal to the equipment management system.

[0016] The launch status monitor includes a drone speed monitor and an adsorption magnetic force monitor. The drone speed monitor is located on the modular adapter and monitors in real time whether the drone speed meets the launch requirements. The adsorption magnetic force monitor is located inside the base plate of the modular adapter and monitors in real time whether the adsorption magnetic force meets the requirements. If any abnormality occurs, a signal is transmitted to the device management system.

[0017] The intelligent integrated management platform includes an information processing system, an equipment management system, and a human-machine interaction system. The information processing system is divided into a UAV information processing system and a data aggregation module. After receiving UAV information, the UAV information processing system integrates it, clarifies the UAV launch mission, and transmits the information to the equipment management system. The data aggregation module is responsible for storing UAV information and launch data, and for verification and comparison. The equipment management system is responsible for controlling the device. The human-machine interaction system interface is installed on the adjustable belt-type launch assembly for easy operation by personnel and to prevent emergencies.

[0018] Corresponding to the aforementioned adjustable belt-type transmitting assembly, the present invention provides a method for adjusting device parameters, which includes the following steps in the order of adjustment: setting device parameters, adjusting the device lateral angle, adjusting the device basic height, adjusting the inclination angle of the transmitting belt segment, adjusting the belt speed, and adjusting the length of the transmitting belt segment.

[0019] The device parameter setting method is as follows: After the UAV completes its own inspection and preparation, it is placed on the UAV lifting structure. Information such as the UAV model, weight, and required launch speed is transmitted to the UAV information processing system. The UAV information processing system receives the above information, processes it, and analyzes the following mechanical and aerodynamic parameters of the UAV:

[0020]

[0021]

[0022] in--

[0023] m T =Total weight of the drone and modular adapter;

[0024] μ = the coefficient of friction between the modular adapter and the electromagnetic adsorber;

[0025] ρ = air density;

[0026]

[0027]

[0028] l = Displacement required for the drone to accelerate;

[0029] θ = Launch tilt angle of the UAV;

[0030] S = Wing area;

[0031] C L =Lift coefficient, which is related to the launch tilt angle;

[0032] Cd = Drag coefficient;

[0033] G = Total gravity of the drone and its modular adapter + electromagnetic attraction force;

[0034] m = weight of the drone;

[0035] The appropriate device parameters are obtained, including the launch tilt angle and belt length. In addition, the height and lateral angle of the device are determined according to the mission type of the UAV launch. Then, a signal is sent to the equipment management system, which issues an instruction to adjust the device parameters to adapt to the UAV launch.

[0036] The method for adjusting the lateral angle of the device is as follows: the equipment management system controls the drive structure to make the transmission-type rotating chassis rotate, the casters can assist the device to rotate to the designated position, the support feet are lowered, and the device is fixed.

[0037] The basic height adjustment method of the device is as follows: the equipment management system issues an instruction to complete the adjustment through the first and second telescopic support arm groups and the moving mechanism in the belt telescopic module. The moving mechanism moves forward a certain distance, the horizontal length of the buffer belt section decreases, the first and second telescopic support arm groups extend upward to a specified height, and the upper layer of the buffer belt section is tilted at a certain angle.

[0038] The method for adjusting the tilt angle of the launch belt section is as follows: The equipment management system keeps the first telescopic support arm group stationary according to the launch tilt angle requirements of the UAV. The second telescopic support arm group and the moving mechanism in the belt telescopic module are started at the same time. The moving mechanism moves forward a certain distance, the horizontal length of the buffer belt section is reduced again, and the second telescopic support arm extends upward to a specified height, so that the launch belt section is tilted at a specified angle in the front and back, and the upper layer of the buffer belt section is tilted at a certain angle.

[0039] The belt speed adjustment method is as follows: the information processing system obtains the launch speed required by the UAV, sets the initial speed of the belt according to the model and weight of the UAV, and sets the initial speed of the belt to ensure that the UAV obtains a stable acceleration during acceleration. The equipment management system controls the speed of the motor connected to the belt shaft, so that the rotation speed of the shaft increases or decreases, thereby increasing or decreasing the overall speed of the belt assembly.

[0040] The method for adjusting the length of the launching belt segment is as follows: the equipment management system sends a signal, and the front and rear telescopic arm groups and the moving mechanism start simultaneously. The front and rear telescopic arm groups provide sufficient horizontal length, and the moving mechanism moves forward a certain distance to reduce the horizontal length of the buffer belt segment and increase the length of the launching belt segment. In order to keep the inclination angle of the launching belt segment unchanged, the second telescopic support arm group also needs to extend upward a certain length at the same time, and the upper layer of the buffer belt segment still remains in an inclined state.

[0041] Corresponding to the above-mentioned belt-type magnetically adjustable UAV launch device, the present invention also discloses a UAV launch method based on belt acceleration, the entire process including: pre-launch preparation, UAV delivery process, UAV launch, and pre-launch preparation for the next launch.

[0042] The pre-launch preparations are as follows: the UAV is matched with the modular adapter, the probe in the support column pops out and connects with the corresponding hole on the UAV, the UAV release arm is erected, the base is locked to the nose plate, the bearing part attaches to the front half of the UAV, and the UAV and the modular adapter are positioned on the UAV lifting structure to await delivery; after the UAV is ready, information is sent to the UAV information processing system, and after the information is confirmed to be correct, the adjustable belt-type launch assembly is adjusted according to the above-mentioned device parameter adjustment method;

[0043] The drone delivery process is as follows: The drone lifting mechanism lowers the drone to a specified height above the electromagnetic adsorption unit. The equipment management system presets the magnetic force of the electromagnetic adsorption and the number of electromagnetic adsorption units to be activated based on the information transmitted by the drone information processing system. The specified number of electromagnetic adsorption units are activated after leaving the projection range of the drone lifting structure platform. The portion of the segmented adapter that is larger than the platform is adsorbed. The segmented adapter moves along with it until the bottom is completely adsorbed. The woven arrangement sensor detects the state of the drone after it falls and determines whether the magnetic adsorption meets the standard. The information is fed back to the equipment management system for judgment. If the standard is not met, the magnetic force of the current adsorption unit is adjusted or other electromagnetic adsorption units are activated to make the segmented adapter firmly adsorbed.

[0044] The drone launch process is as follows: The belt carries the drone and the segmented adapter, accelerating the movement. The lift generated by the drone's wings gradually increases. The launch status monitor monitors the drone's speed and the magnitude of the electromagnetic attraction force in real time to ensure normal launch status. When the drone and the segmented adapter reach the designated launch position, the launch status monitor sends a signal to the equipment management system. The equipment management system determines whether launch is possible. If launch is not possible, emergency measures are taken: the electromagnetic brake is activated, the belt decelerates rapidly, and the launch belt section retains a 20% margin for buffering. When launch is possible, the drone and the segmented adapter reach the designated position, the load-bearing part in the drone release arm is unlocked, the base is unlocked from the front floor, the drone release arm falls forward under the action of inertia, and at the same time, the probe in the rear support structure retracts. Under the action of thrust and aerodynamic force, the drone detaches from the segmented adapter and takes off.

[0045] The preparation process before the next launch is as follows: After the UAV takes off, the designated electromagnetic adsorption unit remains on. The segmented adapter moves with the belt, and the speed of the motor connected to the belt shaft gradually decreases. The belt gradually decelerates during the movement, while the adapter transport track accelerates until the segmented adapter reaches the adapter retrieval belt section at the bottom of the belt chain. The adapter transport track and the adapter retrieval belt section reach the same direction and speed. When the segmented adapter reaches above the front end of the adapter transport track, the adapter detector sends a signal to the equipment management system, the designated electromagnetic adsorption unit is de-energized, and the segmented adapter it carries falls onto the adapter transport track with its bottom surface facing up. At this point, the adapter retrieval is complete.

[0046] Compared with the prior art, the beneficial effects of the present invention are:

[0047] This invention designs the structure of the belt and the adapter, and proposes a method for launching drones using electromagnetic adsorption belt acceleration. The belt acceleration method has a wide range of applications and few limitations, and can achieve the effect of continuous drone launch, improving launch efficiency and enhancing the rapid response capability of drone launch.

[0048] This invention makes full use of the cooperation between software modules and intelligent devices to improve the efficiency of device operation and realize the automation and unmanned operation of UAV launch.

[0049] The above description is merely an overview of the technical solution of the present invention.

Detailed Implementation

[0060] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0061] Example 1

[0062] like Figure 1 As shown, this embodiment provides a belt-mounted magnetically adjustable UAV launcher, including an adjustable belt launch assembly and an intelligent integrated management platform 5; the adjustable belt launch assembly includes a multi-dimensional control module 1, an adjustable launch belt track 2, multiple segmented adapters 3, and a segmented adapter recovery module 4; the adjustable belt launch assembly is equipped with casters 103 at the bottom; the adjustable belt launch assembly is equipped with support feet 104;

[0063] The multi-dimensional control module 1 includes a basic device frame 105, a transmission-type rotating chassis 101, and a height and angle adjustment mechanism 102. The transmission-type rotating chassis 101 is used to adjust the lateral angle of the adjustable belt launch assembly. The height and angle adjustment mechanism 102 includes first and second telescopic support arm assemblies, used to adjust the height of the bottom device of the basic device frame 105 and the tilt angle of the adjustable launch belt track 2. The adjustable launch belt track 2 is mounted in the basic device frame 105 for launching UAVs. The adjustable launch belt track 2 consists of a multi-functional layered belt chain 201, a belt running device 202, a belt telescopic module 203, a launch status monitor 204, and a UAV lifting mechanism 205. An electromagnetic brake can also be installed for emergency braking. The multi-functional layered belt chain 201 is driven and installed on the basic device frame and has multiple layers. Equipped with an electromagnetic adsorber 2011, which contains an electromagnetic adsorption unit 20111 to magnetically attract the segmented adapter 3, for accelerating the UAV during launch; the belt telescopic module 203 includes front and rear telescopic arm assemblies 2031 and a moving mechanism 2032 for adjusting the belt length; the launch status monitor 204 is used to determine whether the launch process is operating normally; the UAV lifting mechanism 205 carries the UAV and the segmented adapter 3 in the early stage of launch, and descends after the designated electromagnetic adsorption unit 20111 is activated so that the UAV and the segmented adapter 3 are attracted by the electromagnetic adsorption unit 20111; the segmented adapter 3 has a probe 3031 and a bearing part 3042 for fixing the UAV and releasing the UAV during launch to complete the launch; the segmented adapter recovery module 4 includes a segmented adapter transport track 402 and a segmented adapter detector 401 for recovering the segmented adapter 3.

[0064] The intelligent integrated management platform 5 includes an information processing system, an equipment management system, and a human-machine interaction system. The information processing system is used to read and process UAV information and summarize launch and equipment data. The equipment management system is used to issue instructions to manage the adjustable belt launch assembly. The human-machine interaction system is connected to the display screen on the adjustable belt launch assembly for operator processing.

[0065] Specifically, a rotating shaft is provided at the center of the bottom of the transmission-type rotating chassis 101, and a transmission chain is provided on the outer ring. The transmission gear is driven by a motor, and the transmission gear meshes with the transmission chain to drive the transmission chain to rotate, so that the chassis can rotate at uniform intervals, thereby accurately rotating the chassis to the required position.

[0066] Specifically, the height and angle adjustment structure 102 includes a first telescopic support arm group 1021 and a second telescopic support arm group 1022. The telescopic support arm is connected to the belt shaft 2021 and cooperates with the belt telescopic module 203 included in the adjustable launch belt track to complete the adjustment of the height of the bottom device and the tilt angle of the adjustable launch belt track 2.

[0067] Furthermore, the telescopic support arm includes a telescopic motor and a telescopic rod, with both ends of the telescopic rod connected to the output end of the telescopic motor and the outer wall side of the upper rotating shaft 2021 of the belt-driven device 202, respectively. The vertical movement of the telescopic support arm can be achieved by synchronously driving the two motors to rotate forward or in reverse.

[0068] Specifically, the belt running device 202 includes four sets of belt shafts 2021 and a first motor 2022. The first motor is fixed on the basic frame 105 of the device. The two sets of belt shafts 2021 on the upper layer are respectively connected to the first telescopic support arm group 1021 and the second telescopic support arm group 1022. The other two sets are fixed on the basic frame 105 of the device. The first motor 1022 is connected to one of the sets of belt shafts 2021 to provide the main driving force.

[0069] Furthermore, the belt shaft 2021 is connected to the side wall of the basic frame 105 of the device and the first telescopic support arm group 1021 and the second telescopic support arm group 1022. The shaft body 20213 is hollow and contains a wireless charging device 20211 for powering the electromagnetic adsorber 2011 included in the multifunctional layered belt chain 201. The pulleys 20212 on both sides of the shaft body are fitted and fastened to the special belt 2013.

[0070] Specifically, the multi-functional layered belt chain 201 is divided into three layers inside the basic frame 105 of the device: the top layer is the launch belt segment, the middle layer is the buffer belt segment, and the bottom layer is the adapter recovery belt segment. The launch belt segment retains 20% of its capacity as an emergency buffer zone for UAV launch.

[0071] Specifically, the belt telescopic module 203 includes a front and rear telescopic arm assembly 2031 and a moving mechanism 2032. The front and rear telescopic arm assembly 2031 is used to provide sufficient horizontal length when adjusting the belt length, and the moving mechanism 2032 is responsible for reducing the length of the middle buffer belt section to adjust the device parameters.

[0072] Furthermore, the moving mechanism 2032 relies on the micro motor 203223 to drive the motion gear 203222 to mesh with the rack path 203221 to move, so that the moving mechanism can move precisely. The transverse push rod 20323 connects the support arms at both ends. The upper end of the support arm assembly 20321 has a small belt rotating shaft 203211, which is responsible for pressing the belt to engage with the belt drive half pulley 203212 to ensure the stability of the belt assembly.

[0073] Furthermore, the motion gear 203222 is divided into two groups, left and right, with two gears in each group located in the housings on both sides of the transverse push rod 20323. The micro motor 203223 is located inside the motion gears within the housings, driving the motion gear 203222 to roll. The teeth of the motion gear 203222 are spur teeth, and the tooth profile of the rack path 203221 is a straight line with evenly distributed spur teeth, which mesh with the motion gear 203222 to convert rolling into movement.

[0074] Furthermore, the length of the belt miniature shaft 203211 is relatively small, the distance between the two sets of belt miniature shafts 203211 is greater than the width of the segmented adapter, and the four belt miniature shafts 203211 form a group to alternately press the belt. The belt drive half pulley 203212 only needs to engage with the belt on its outer side.

[0075] Specifically, the multi-functional layered belt chain 201 is composed of multiple belts spliced ​​together. The multi-functional layered belt structure is divided into upper and lower parts. The main body of the lower part is a special-shaped belt 2013, which is in the shape of an inverted trapezoid. The upper layer of the special-shaped belt 2013 has a woven sensor 2012 embedded in it to detect the state of the belt during the delivery process of the UAV to reflect the degree of completion of the delivery process. The upper part is an electromagnetic adsorber 2011, which is powered by a wireless charging device 20211 in the belt shaft 2021. The electromagnetic adsorber is used to adsorb the modular adapter 3 connected to the UAV. Furthermore, the special-shaped belt 2013 is made of polyurethane to enhance its anti-wear properties and suitability for conveying heavy loads and high-speed transmission. The belt edge has a special-shaped through-hole. The pulley 20212 has a bevel gear shape. The special-shaped through-hole matches the teeth of the pulley 20212 to fasten the belt. The braided sensor 2012 is embedded in the upper layer of the special-shaped belt 2013 in a "well" pattern. Its main function is to monitor the stress on the belt and report the relevant information to the equipment management system, which then processes the information accordingly.

[0076] Further, the structure of the electromagnetic adsorbent 2011 includes an electromagnetic adsorption unit 20111, a buffer elastomer 20112, and a wireless charging receiver 20113. The electromagnetic adsorption unit 20111 is rectangular and includes an electromagnet body, a coil disposed on the electromagnet body, and a contact surface with the object. One end is located on the upper surface of the electromagnetic adsorbent 20111 housing for contacting the lower end of the segmented adapter 3 and generating an adsorption effect on it. The other end is connected to the inner top surface of the electromagnetic adsorbent 2011 housing through the buffer elastomer 20112. The wireless charging receiver 20113 is located inside the lower surface of the electromagnetic adsorbent 2011 housing and is connected to the electromagnetic adsorption unit 20111 through the coil for receiving the wireless charging device 20211. The electrical energy is transmitted to the electromagnetic adsorption unit 20111. A baffle is provided on one side of the electromagnetic adsorption unit 20111. A photoelectric sensor is provided on the inner wall of the electromagnetic adsorption unit 2011 housing, which is located slightly below the baffle, to send information when the baffle is detected. When the bottom surface of the electromagnetic adsorption unit 20111 contacts the segmented adapter 3, the electromagnetic adsorption unit 20111 moves downward. The buffer elastic body 20112 generates increasing elastic pressure on the electromagnetic adsorption unit 20111, and the electromagnetic adsorption unit 20111 will become increasingly closer to the segmented adapter 3. After reaching a certain degree, the photoelectric sensor detects the baffle and generates a trigger signal to reach the equipment management system, thereby energizing the electromagnetic adsorption unit 20111 to produce an adsorption effect.

[0077] Specifically, the modular adapter 3 is composed of multiple base plates 301, with flexible filler 302 between the base plates 301, allowing the adapter to bend via a belt. A drone release arm 304 and a rear support structure 303 are mounted on the top of the base plates of the modular adapter. The rear support structure 303 includes a support column 3032 and a probe 3031 located inside it, symmetrically installed on both sides of the tail base plate among the multiple base plates 301 of the modular adapter 3. The probe 3031 can extend out and connect to the drone. The drone release arm 304, located on the center line, is mounted on the front end of the head base plate among the multiple base plates 301 of the modular adapter 3 via a pivot. Torsion springs are provided on both sides of the drone release arm 304 to allow the drone release arm to maintain a forward tilting tendency. Its base 3043 is located inside the head base plate and is locked to the head base plate by electromagnetic adsorption. A bearing part 3042 is provided on the upper part to control the fixing and release of the drone by electromagnetic adsorption. Furthermore, the base plate 301 of the segmented adapter 3 is made of wear-resistant metal to reduce wear and improve usability. The flexible filler 302 wraps around the side of the base plate 301 and is strongly bonded to it. The material is the same as that of the special belt 2013, which can achieve the required degree of bending when the multi-functional layered belt 201 passes through the pivot bend. The probe 3031 structure on the upper surface of the rear support structure 303 is combined with the probe hole on the drone. The support column 3032 includes a probe ejection mechanism and a motor. The probe 3031 is ejected and retracted by the extension and retraction of the spring. After unlocking, the drone release arm 304 falls forward. After falling, the rear surface of the drone release arm 304 is on the same plane as the upper surface of the base plate 301.

[0078] Specifically, the segmented adapter recycling module 4 is located inside the bottom of the basic frame 105 of the device, and includes an adapter transport track 401 and an adapter detector 402. The adapter transport track 401 is composed of a belt. The width of the adapter transport track 401 is equal to the distance between the support column 3032 in the rear support structure 303 of the segmented adapter 3. The height of the adapter transport track 401 above the ground is greater than the height of the rear support structure 303. The distance between the adapter transport track 401 and the adapter recycling belt section is slightly greater than the height of the base plate 301 of the segmented adapter 3. The adapter detector 401 is responsible for confirming the segmented adapter 3 and sending a signal to the equipment management system.

[0079] Furthermore, the adapter detector 401 includes a laser emitting device and a laser receiving device. The position and size of the laser emitting device match the position and size of the laser receiving device. The adapter detector 401 is located above the beginning of the adapter transport track 402. If the segmented adapter 3 passes between the laser emitting device and the laser receiving device, and the laser receiving device cannot receive the laser, it will send a signal to the equipment management system 6. The equipment management system 6 will make a judgment, and the corresponding electromagnetic adsorber 2011 in the multi-functional layered belt chain 201 will be de-energized. The segmented adapter will fall to the adapter transport track and finally start the next cycle.

[0080] Specifically, the launch status monitor 204 includes a drone speed monitor and an adsorption magnetic force monitor. The drone speed monitor is located on the modular adapter 3 and monitors in real time whether the drone speed meets the launch requirements. The adsorption magnetic force monitor is located inside the base plate of the modular adapter 3 and monitors in real time whether the adsorption magnetic force meets the requirements. Any abnormal situation can send a signal to the device management system.

[0083] Specifically, the intelligent integrated management platform 5 includes an information processing system, an equipment management system, and a human-machine interaction system. The information processing system is divided into a UAV information processing system and a data aggregation module. After receiving UAV information, the UAV information processing system integrates it, clarifies the launch requirements of the UAV, and transmits the information to the equipment management system. The data aggregation module is connected to the equipment management system and the UAV information processing system, and is responsible for storing UAV information and launch data, and for verification and comparison.

[0084] Example 2

[0085] Corresponding to the above-mentioned device adjustment structure and intelligent integrated management platform, this embodiment provides a method for adjusting device parameters. The entire process, in the order of adjustment, includes: device parameter setting, device lateral angle adjustment, device basic height adjustment, launching belt section tilt angle adjustment, belt speed adjustment, and launching belt section length adjustment.

[0086] The device parameter setting method is as follows: After the UAV completes its own inspection and preparation, it is placed on the UAV lifting structure 205. Information such as the UAV model, weight, and required launch speed is transmitted to the UAV information processing system. The UAV information processing system receives the above information, processes it, and analyzes the following mechanical and aerodynamic parameters of the UAV:

[0087]

[0088]

[0089] in--

[0090] m T =Total weight of the drone and modular adapter;

[0091] μ = the coefficient of friction between the modular adapter and the electromagnetic adsorber;

[0092] ρ = air density;

[0093]

[0094]

[0095] l = Displacement required for the drone to accelerate;

[0096] θ = Launch tilt angle of the UAV;

[0097] S = Wing area;

[0098] C L =Lift coefficient, which is related to the launch tilt angle;

[0099] C d = Drag coefficient;

[0100] G = Total gravity of the drone and its modular adapter + electromagnetic attraction force;

[0101] m = weight of the drone;

[0102] The appropriate device parameters are obtained, including the launch tilt angle and belt length. In addition, the height and lateral angle of the device are determined according to the mission type of the UAV launch. Then, a signal is sent to the equipment management system, which issues an instruction to adjust the device parameters to adapt to the UAV launch.

[0103] The method for adjusting the lateral angle of the device is as follows: the equipment management system controls the drive structure to make the transmission-type rotating chassis 101 rotate, the casters 103 can assist the device to rotate to the designated position, the support feet 104 are lowered, and the device is fixed.

[0104] The basic height adjustment method of the device is as follows: the equipment management system issues an instruction, and the adjustment is completed through the first telescopic support arm 1021 and the second telescopic support arm 1022 group and the moving mechanism 2032 in the belt telescopic module 203. The moving mechanism 2032 moves forward a certain distance, the horizontal length of the buffer belt section decreases, the first telescopic support arm 1021 and the second telescopic support arm 1022 extend to a specified height, and the upper layer of the buffer belt section is tilted at a certain angle.

[0105] The method for adjusting the launch belt section tilt angle is as follows: According to the launch tilt angle requirements of the UAV, the equipment management system keeps the first set of telescopic support arm group 1021 stationary, and the second set of telescopic support arm group 1022 and the moving mechanism 2032 in the belt telescopic module 203 are started at the same time. The moving mechanism 2032 moves forward a certain distance, the horizontal length of the buffer belt section is reduced again, and the second telescopic support arm 1022 extends upward to a specified height, so that the launch belt section is tilted at a specified angle, and the upper layer of the buffer belt section is tilted at a certain angle.

[0106] The belt speed adjustment method is as follows: the information processing system obtains the launch speed required by the UAV, sets the initial speed of the belt according to the model and weight of the UAV, and sets the initial speed of the belt to ensure that the UAV obtains stable acceleration during acceleration. The equipment management system controls the motor 2022 connected to the belt shaft 2021 to change the rotation speed of the shaft 2021, thereby changing the overall speed of the belt assembly.

[0107] The method for adjusting the length of the launching belt segment is as follows: the equipment management system sends a signal, and the front and rear telescopic arm groups 2031 and the moving mechanism 2032 start simultaneously. The front and rear telescopic arm groups 2031 provide sufficient horizontal length, and the moving mechanism 2032 moves forward a certain distance to reduce the horizontal length of the buffer belt segment and increase the length of the launching belt segment. In order to keep the inclination angle of the launching belt segment unchanged, the second telescopic support arm group 1022 also needs to extend and retract upward a certain length at the same time, and the upper layer of the buffer belt segment still remains in an inclined state.

[0108] Corresponding to the aforementioned adjustable belt-type launch assembly, this invention also discloses a UAV launch method based on belt acceleration, the entire process of which includes: pre-launch preparation, UAV delivery process, UAV launch, and pre-launch preparation for the next launch.

[0109] The pre-launch preparation work is as follows: the UAV is matched with the modular adapter 3, the probe 3031 in the rear support column 303 pops out and connects with the corresponding hole on the UAV, the UAV release arm 304 is erected, the base 3043 is locked with the front bottom plate, the bearing part 3042 adsorbs the front half of the UAV, the UAV and the modular adapter 3 are positioned on the UAV lifting mechanism 205 and are waiting to be delivered. After the UAV is ready, it sends information to the UAV information processing system. After the information is confirmed to be correct, the adjustable belt-type launch assembly is adjusted according to the above-mentioned device parameter adjustment method.

[0110] The drone delivery process is as follows: The drone lifting mechanism 205 lowers the drone to a predetermined height above the electromagnetic adsorption unit 20111. The equipment management system presets the magnetic force of the electromagnetic adsorption and the number of electromagnetic adsorption units 20111 to be activated based on the information transmitted by the drone information processing system 501. The predetermined number of electromagnetic adsorption units 20111 are activated after leaving the platform projection range of the drone lifting mechanism 205. The portion of the segmented adapter 3 that is larger than the platform is adsorbed. The segmented adapter 3 moves along with it until the bottom is completely adsorbed. The woven arrangement sensor 2012 detects the state of the drone after it falls and determines whether the magnetic adsorption meets the standard. It feeds back the information to the equipment management system 6. If it does not meet the standard, it adjusts the magnetic force of the currently determined electromagnetic adsorption unit 2011 or activates other electromagnetic adsorption units 2011 to perform magnetic adsorption so that the segmented adapter 3 is stably adsorbed.

[0111] The drone launch process is as follows: The belt carries the drone and the segmented adapter 3, accelerating the movement. The lift generated by the drone's wings gradually increases. The launch status monitor 204 monitors the drone's speed and the magnitude of the electromagnetic attraction force in real time to ensure normal launch status. When the drone and the segmented adapter 3 reach the designated launch position, the launch status monitor 204 sends a signal to the equipment management system. The equipment management system determines whether launch is possible. If launch is not possible, emergency measures are taken: the electromagnetic brake is activated, the belt decelerates rapidly, and the launch belt segment retains a 20% margin for buffering. When launch is possible, the drone and the segmented adapter reach the designated position, the bearing part 3042 in the adapter release arm 304 is unlocked, the base and the front bottom plate are unlocked, the drone release arm falls forward under the action of inertia, and at the same time, the probe 3031 in the rear support structure 303 retracts. Under the action of thrust and aerodynamic force, the drone detaches from the segmented adapter 3 and takes off.

[0112] The next launch preparation process is as follows: After the UAV takes off, the designated electromagnetic adsorption unit 20111 remains in a charging state. The segmented adapter 3 moves with the belt, and the speed of the motor 2022 connected to the belt shaft gradually decreases. The belt gradually decelerates during the movement, while the adapter transport track 402 accelerates until the segmented adapter 3 reaches the adapter retrieval belt section located at the bottom of the belt chain. The adapter transport track 402 and the adapter retrieval belt section reach the same direction and speed. When the segmented adapter 3 reaches the front end of the adapter transport track with the belt, the adapter detector 401 sends a signal to the equipment management system, the designated electromagnetic adsorption unit 20111 is de-energized, and the segmented adapter 3 it carries falls onto the adapter transport track 402 with its bottom surface facing upwards. At this point, the adapter retrieval is completed.
