Description

Technical Field

[0001] This invention relates to the field of training and examination systems for unmanned aerial vehicles (UAVs) in the power industry, specifically to a multi-rotor UAV operation training and examination system, method, and operating device. Background Technology

[0002] Currently, the application of drones is gradually extending from the military field to the civilian field, and its application scope is constantly expanding, becoming increasingly mature in industries such as power, consumer electronics, plant protection, security, and surveying. Drones are playing an increasingly important role in the national economy and social production and daily life.

[0003] In recent years, the introduction and application of inspection drones have solved an urgent problem for the power industry. Traditional manual inspection methods have long been criticized for their shortcomings in safety, cost, and efficiency, making it difficult to keep pace with industry development. The application of drone inspections, however, offers a promising future. Because drones can conduct large-scale aerial inspections, the accuracy of inspections is significantly improved through the use of sensors and cameras. Furthermore, drone inspections overcome limitations imposed by terrain and weather conditions, resulting in substantial improvements in both the safety and efficiency of inspection work.

[0004] To make drone operation more professional, legal, and standardized, and to provide professional skills support for the rapid development of the industry, there is an increasing demand in society for highly qualified and skilled operators. Currently, drone training and testing in the power industry still rely on conventional methods, requiring a large number of experienced instructors, and the quality assessment of training and testing depends primarily on the subjective judgment of examiners. This training and testing approach makes it difficult to standardize training, improve training efficiency, ensure fair and reliable quality assessment, and increases training costs. Therefore, further improvements to the training and testing system are needed. Summary of the Invention

[0005] This invention provides a multi-rotor drone operation training and examination system, method, and operating device to solve the problems of difficulty in unifying training standards and low training efficiency in existing drone training and examination.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-rotor UAV operation training and examination system includes: a lidar unit module, an area control module, a transmit and receive module, a signal processing module, a central control module, a 5G signal transmission module, a Bluetooth transmission module, and a display module;

[0008] The lidar unit module includes an outer ring lidar unit module chain and an inner ring lidar unit module chain. The outer ring lidar unit module chain surrounds the inner ring lidar unit module chain to form a concentric circle structure of the lidar unit module chain. The two concentric circle structure lidar unit module chains intersect to form an "8" shaped lidar unit module chain.

[0009] The outer ring lidar unit segment assembly chain and the inner ring lidar unit segment assembly chain include several lidar unit segment components. Each lidar unit segment component includes: a lidar emitter, a lidar receiver, a lidar unit segment component controller, and a first photoelectric buzzer. A blue laser phototube is installed inside the lidar emitter, and a red laser phototube is installed inside the lidar receiver. The lidar unit segment component controller is connected to the lidar emitter, the lidar receiver, and the first photoelectric buzzer.

[0010] The area control module, connected to the central control module and the lidar unit module, is used to control the opening or closing of the plurality of lidar unit modules.

[0011] The transmit / receive module is connected to the central control module and the lidar unit module, and is used to control the lidar transmitter to transmit signals and control the lidar receiver to receive signals.

[0012] The signal processing module, connected to the central control module, the transmitting and receiving module, and the lidar unit module, is used to control the lidar transmitter to emit blue lidar waves and to control the lidar receiver to emit red lidar waves when the lidar receiver is receiving signals, while simultaneously controlling the first photoelectric buzzer to emit an alarm sound.

[0013] The 5G signal transmission module and the Bluetooth transmission module are respectively connected to the central control module and are used to transmit signals from the central control module.

[0014] The display module is connected to the central control module and is used to display signal information from the central control module.

[0015] Furthermore, the outer ring lidar unit segment assembly chain and the inner ring lidar unit segment assembly chain include several lidar unit segment assembly chain segments, each lidar unit segment assembly chain segment includes 8 lidar unit segment sub-components, the 8 lidar unit segment sub-components are arranged in two rows, with 4 lidar unit segment sub-components in each row.

[0016] Furthermore, the two concentric radar unit segment assembly chains are divided into 12 regions in the form of a 12-hour clock.

[0017] A multi-rotor UAV operation training and examination device, based on the aforementioned training and examination system, includes a control panel, an antenna, and a multi-function display screen. One end of the control panel is connected to the multi-function display screen via a rotating shaft. The antenna is installed on both sides of the control panel. In use, the control panel controls the outer ring lidar unit module chain and the inner ring lidar unit module chain, and communicates with the lidar unit module chain through the antenna, ultimately displaying the communication signal information on the multi-function display screen.

[0018] Furthermore, the control panel includes: radar unit chain connection indicator light, main switch, second photoelectric buzzer, power indicator light, I zone outer ring radar unit section switch, I zone inner ring radar unit section switch, II zone outer ring radar unit section switch, II zone inner ring radar unit section switch, I zone outer ring digital connection light, I zone inner ring digital connection light, II zone outer ring digital connection light and II zone inner ring digital connection light;

[0019] The outer ring radar unit switch of Zone I, the inner ring radar unit switch of Zone I, the outer ring radar unit switch of Zone II, and the inner ring radar unit switch of Zone II are each set in a row on the control panel. The row above the outer ring radar unit switch of Zone I is set with the corresponding digital connection light of the outer ring of Zone I, the row above the inner ring radar unit switch of Zone I is set with the corresponding digital connection light of the inner ring of Zone I, the row above the outer ring radar unit switch of Zone II is set with the corresponding digital connection light of the outer ring of Zone II, and the row above the inner ring radar unit switch of Zone II is set with the corresponding digital connection light of the inner ring of Zone II.

[0020] The main switch, radar unit chain connection indicator, second photoelectric buzzer, and power indicator are arranged in the same row on the upper surface of the control panel near the multi-function display screen.

[0021] Furthermore, the outer ring radar unit switch of Zone I, the inner ring radar unit switch of Zone I, the outer ring radar unit switch of Zone II, and the inner ring radar unit switch of Zone II are three-position switches, namely the off position, the first position, and the second position.

[0022] A training and examination method for operating a multi-rotor unmanned aerial vehicle (UAV), based on the aforementioned operating device, includes the following steps:

[0023] Connect the outer ring lidar unit component chain and the inner ring lidar unit component chain to the power supply, and then turn on the main switch to connect with the outer ring lidar unit component chain and the inner ring lidar unit component chain. At this time, the lidar unit chain connection indicator light will flash. After the connection is completed, the lidar unit chain connection indicator light will stay on green.

[0024] After the radar unit chain connection indicator light is constantly on green, turn on the outer ring radar unit section switch of Zone I, the inner ring radar unit section switch of Zone I, the outer ring radar unit section switch of Zone II, and the inner ring radar unit section switch of Zone II. At this time, the corresponding outer ring digital connection light of Zone I, the inner ring digital connection light of Zone I, the outer ring digital connection light of Zone II, and the inner ring digital connection light of Zone II will light up.

[0025] When the training and examination are over, first turn off the outer ring radar unit switch of Zone I, the inner ring radar unit switch of Zone I, the outer ring radar unit switch of Zone II, and the inner ring radar unit switch of Zone II. Then turn off the main switch. Finally, disconnect the power to the outer ring lidar unit assembly chain and the inner ring lidar unit assembly chain.

[0026] Furthermore, it also includes the following steps:

[0027] When the UAV flies in a figure-eight pattern, the outer ring radar unit switch of section I, the inner ring radar unit switch of section I, the outer ring radar unit switch of section II, and the inner ring radar unit switch of section II are turned on; at the same time, the outer ring radar unit switch of section I, the inner ring radar unit switch of section I, the outer ring radar unit switch of section II, and the inner ring radar unit switch of section II at the intersection of the two concentric circle radar unit component chains are turned off.

[0028] Furthermore, it also includes the following steps:

[0029] When the UAV flies in a circle, simultaneously turn on the outer ring radar unit switch of Zone I and the inner ring radar unit switch of Zone I, or simultaneously turn on the outer ring radar unit switch of Zone II and the inner ring radar unit switch of Zone II.

[0030] Furthermore, when the outer ring radar unit switch of Zone I, the inner ring radar unit switch of Zone I, the outer ring radar unit switch of Zone II, and the inner ring radar unit switch of Zone II are all in the same position, the outer ring lidar unit assembly chain and the inner ring lidar unit assembly chain emit red lidar waves and blue lidar waves.

[0031] When the outer ring radar unit switch of Zone I, the inner ring radar unit switch of Zone I, the outer ring radar unit switch of Zone II, and the inner ring radar unit switch of Zone II are in position two, the outer ring lidar unit assembly chain and the inner ring lidar unit assembly chain only transmit radar waves.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] This invention provides a multi-rotor UAV operation training and examination system, including a lidar unit module, an area control module, a transmit / receive module, a signal processing module, a central control module, a 5G signal transmission module, a Bluetooth transmission module, an alarm module, and a display module. The lidar unit module comprises a figure-eight-shaped chain of radar unit modules, which can be arbitrarily combined into the required individual system modes according to different training needs, unifying training and examination standards, improving training and examination efficiency, and meeting the requirements of UAV operation training and examination.

[0034] This invention provides a multi-rotor UAV operation training and examination device. The device is simple to operate and has a concise structure. It can control the outer ring lidar unit segment assembly chain and the inner ring lidar unit segment assembly chain in different areas through the control panel, thereby improving the efficiency of training and examination and meeting the needs of UAV operation training and examination under different conditions.

[0035] This invention provides a method for training and testing the operation of multi-rotor unmanned aerial vehicles (UAVs). By controlling the outer ring lidar unit segment assembly chain and the inner ring lidar unit segment assembly chain, this method can standardize UAV training and testing, improve the efficiency of training and testing, and meet the needs of UAV operation training and testing.

[0043] In the following description, only certain exemplary embodiments are briefly described. The described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and descriptions are considered to be exemplary in nature and not restrictive.

[0044] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0048] The multi-rotor drone operation training and examination system provided by this invention includes multiple sets of lidar (red and blue laser photoelectric tube arrays), Bluetooth interconnection, an integrated control system, a display screen, alarm flashing, etc. This system can be arbitrarily combined into any individual system mode to meet the needs of drone operation training and examination. A multi-rotor drone operation training and examination system includes: multiple sets of lidar chains (composed of lidar unit modules), an integrated control system, a Bluetooth system, alarm flashing, a 5G transmission system, a microprocessor, a multi-functional operation control box, etc.

[0049] like Figure 1 As shown, the outer ring lidar unit segment assembly chain 1 is tightly attached to the outer side of the figure-eight training area's circular ring, while the inner ring lidar unit segment assembly chain 2 is tightly attached to the inner side of the figure-eight training area's circular ring. The figure-eight training area is divided into two regions, I and II. At the intersection of the two regions' circular rings, lidar unit segments are laid out on both the inner and outer sides of each ring, and can independently form a closed lidar unit segment assembly chain to meet the needs of multi-rotor UAV circular flight control training. Each lidar unit segment of the inner and outer rings adopts an independent opening or closing design, facilitating the inspection and replacement of the inner and outer lidar unit segment assemblies in regions I and II.

[0050] like Figure 2 As shown, the lidar transmitter 2-1 and the lidar receiver 2-2 have a certain inward angle relative to the horizontal plane, which facilitates better reception of the emitted radar waves. Lidar transmitter 2-1 is equipped with a blue laser phototube, which can emit a blue laser beam; lidar receiver 2-2 is equipped with a red laser phototube, which can emit a red laser beam. The lidar unit section component control module 2-3 controls the emission of radar waves from lidar transmitter 2-1 and the reception of reflected radar waves from lidar receiver 2-2, and also controls the first photoelectric buzzer 2-4 to emit an alarm sound and a flashing red light. The emission of blue and red laser beams allows for better observation of the specific location of the multi-rotor UAV flying out of the designated area, especially on cloudy days or at dusk.

[0051] like Figure 3 As shown, the lidar unit segment assembly chain consists of 8 lidar unit segments arranged in two rows of 4. This design is advantageous for multi-rotor UAVs, ensuring they are detected by radar waves when flying out of the training area. Simultaneously, the lidar unit segment assembly chains, laid inside and outside the circular rings of areas I and II of the figure-eight training area, are divided into 12 zones according to a 12-hour clock. The lidar unit segments in the 12 zones of the inner and outer rings can be individually controlled to turn on or off. That is, according to the requirements of the training program, turning on or off the lidar unit segments in zone I or II allows for circular flight training within zone I or II. When the lidar unit segments in the intersecting area of ​​zones I and II are turned off, the requirement for figure-eight flight can be met.

[0052] like Figure 4 As shown, the microprocessor is the core of the multi-rotor UAV operator training and examination system, connecting other modules and systems and playing a crucial role in its operation. The area control system, through the microprocessor, can individually control the activation or deactivation of each lidar unit segment within the 12 inner and outer rings of the figure-eight training area (zones I and II). The transmission and reception system controls the signal transmission and reception of each lidar unit segment component within the 12 areas. The signal processing system can control each lidar unit segment component within the inner and outer rings of zones I and II to emit blue lidar waves, and can also control each lidar unit segment component to emit red laser waves and emit an alarm sound when it receives reflected radar waves. The 5G and Bluetooth transmission systems ensure signal transmission connections between the entire system and monitoring and operating personnel; the operating personnel receive signals via headsets. All of the above signal information can be displayed on the screen via the microprocessor.

[0053] like Figure 5The diagram shows a multi-rotor UAV operation training and testing device (multi-functional operation control box). The multi-functional display screen 4 is a multi-functional touchscreen that can be attached to the control panel 6 via a hinge. The control box has two antennas 3, designed for multi-directional communication with the lidar unit cluster assembly chain and the operator. The control panel 6 has a master switch 16 (light), which is the power button for the device. The lidar unit cluster connection indicator 15 illuminates, indicating a successful connection to the lidar unit cluster assembly chain. The control panel 6 has four rows of switches: switch 7 for the outer ring of zone I, switch 8 for the inner ring of zone I, switch 9 for the outer ring of zone II, and switch 10 for the inner ring of zone II. Each row has 12 switches, and each switch controls the connection status of the lidar unit clusters in one zone. Each row of switches has a corresponding row of indicator lights at its top: Digital connection light 11 for the outer ring of Zone I, Digital connection light 12 for the inner ring of Zone I, Digital connection light 13 for the outer ring of Zone II, and Digital connection light 14 for the inner ring of Zone II. Each row has 12 digital connection lights. Whether each light is lit indicates whether the radar unit segment in that area is connected. The unit segment switch has three positions: off, on (position 1), and on (position 2). Pushing the switch down is off, and pushing it up is on. Pushing it once is on (position 1), in which case the lidar unit segment emits a red laser beam, a blue laser beam, and radar waves; pushing it twice is on (position 2), in which case the lidar unit segment emits only radar waves, and the red and blue laser beams are off. The power indicator lights 17 on the control panel 6 have five lights in total. When all five lights are lit, it means that the multi-functional operation control box is fully charged. When only one light is lit, it indicates that the multi-functional operation control box needs to be charged. In addition, the multi-functional operation control box can also be used directly by plugging it in. When the small component of the laser radar unit alarms, it will be fed back to the multi-functional operation control box through the second photoelectric buzzer 5.

[0054] The multi-rotor UAV operation training and examination method provided by this invention is described in detail below:

[0055] First, connect the power supply to the outer ring lidar unit segment assembly chain 1 and the inner ring lidar unit segment assembly chain 2 of the figure-eight training area. After turning on the main power switch 16 of the multi-function operation control box, you can then dock with the powered and functioning inner and outer ring lidar unit segment assembly chains. The red and green lights on the main switch 2 will stop flashing, and the green light will illuminate, indicating that the docking is complete. Then, turn on the outer ring lidar unit segment switch 7 of zone I, the inner ring lidar unit segment switch 8 of zone I, the outer ring lidar unit segment switch 9 of zone II, and the inner ring lidar unit segment switch 10 of zone II in sequence, pushing them all up to the 'on' position 2. At this time, the digital connectivity lights 11, 12, 13, 14 of the outer ring lidar unit segment in zone I and zone II will all illuminate. However, the lidar unit segment assemblies in the outer and inner rings of the intersection area of ​​zone I and zone II should be turned off. This will meet the requirements for figure-eight flight. If you only need to train multi-rotor UAVs to fly in circles in Zone I or Zone II, you need to turn on Zone I outer ring radar unit switch 7 and Zone I inner ring radar unit switch 8 separately on the multi-function operation control box. At the same time, Zone I outer ring digital connectivity light 11 and Zone I inner ring digital connectivity light 12 will also light up. Turn off Zone II outer ring radar unit switch 9 and Zone II inner ring radar unit switch 10. At the same time, Zone II outer ring digital connectivity light 13 and Zone II inner ring digital connectivity light 14 will also be in the off state. At this time, you can perform multi-rotor UAV circular control flight in Zone I. Conversely, to perform circular control flight of a multi-rotor UAV within Zone II, it is necessary to separately turn on the outer ring radar unit switch 9 and the inner ring radar unit switch 10 of Zone II, ensuring that the outer ring digital connection light 13 and the inner ring digital connection light 14 of Zone II are in the on state, and turn off the outer ring radar unit switch 7 and the inner ring radar unit switch 8 of Zone I, ensuring that the outer ring digital connection light 11 and the inner ring digital connection light 12 of Zone I are in the off state. At this time, it is possible to perform circular control flight of a multi-rotor UAV within Zone II.

[0056] During training flights of a multi-rotor drone in circles or figure-eight patterns, when the drone flies out of the designated area, it will touch the lidar unit segment of that area. At this time, the lidar emitter 2-1 emits a blue laser beam lidar wave, and the lidar receiver 2-2 of the lidar unit segment in that area receives the reflected radar wave and emits a red laser wave. The first photoelectric buzzer 2-4 also emits an alarm sound and flashes a red light. Based on the location of the red laser wave, alarm sound, and flashing red light, the operator can determine whether the multi-rotor drone has flown out of or into the circle, and can adjust the flight attitude of the multi-rotor drone in time. At the same time, the second photoelectric buzzer 5 on the control panel 6 emits a flashing light and a buzzing sound, and the zone lights of the inner and outer ring digital connection lights of Zone I and Zone II also flash, reminding the operator to pay attention. The area where the multi-rotor drone has flown out can be accurately seen through the multi-function display screen on the multi-function control box or the zone indicator lights on the panel. The operator can be promptly reminded to adjust the flight attitude of the multi-rotor drone through the headset; this can also be recorded as an examination.

[0057] When training the control and flight of a multi-rotor drone on a cloudy day or at dusk, it is necessary to push all the switches of the inner and outer ring radar unit sections of Zone I and Zone II down to the "on" position on the control panel 6. At this time, the red and blue laser beams emitted by the lidar unit section components are in the "on" state, which can better observe the specific location of the multi-rotor drone flying out of the designated area.

[0058] The entire system is equipped with Bluetooth and 5G transmission systems to ensure signal transmission between the system and monitoring and control personnel. The control personnel receive signals through headsets.

[0059] As is known from common technical knowledge, the present invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones; all modifications within the scope of the present invention or equivalent to the scope of the present invention are included in the present invention.
