Description

Technical Field

[0001] This invention relates to the field of drone maintenance, and more particularly to an outdoor platform for the maintenance of power line inspection drones. Background Technology

[0002] Power line inspection drones are unmanned aerial vehicles equipped with sensors for inspecting power equipment. They can quickly and flexibly monitor key areas such as transmission lines and substations, promptly detect potential faults, and have remote operation capabilities to ensure the safe operation of the power grid. Compared with manual inspection, they are more efficient and safer and are widely used in power systems.

[0003] In existing technologies, some drones may experience power shortages or crash due to impacts during inspections. When a drone is at risk of crashing, the inspection information stored on it may be lost. To avoid the leakage of important information, drones need to accurately transmit information to the destination to achieve information communication. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an outdoor platform for power line inspection drone maintenance.

[0005] This invention provides an outdoor platform for power line inspection drone maintenance, including a support frame, and further comprising:

[0006] The platform is fixed to the top of the bracket;

[0007] Two electromagnets are symmetrically fixedly installed on the top of the platform, and their tops are flush with the top of the platform.

[0008] A magnetic charger is mounted on the top of the platform via a telescopic rod, which is used to push the magnetic charger to move vertically;

[0009] The protective cover is mounted on the top of the platform via an electric drive component to drive the protective cover to flip and switch between opening and closing.

[0010] The control unit is used to control the drones that enter the specified range to communicate, so as to exchange information based on the information of the drones and realize corresponding control.

[0011] During flight, if the drone flies into the coverage area of ​​an outdoor platform, the control unit detects the drone and interacts with it to receive its flight information. If the drone's battery is low, the control unit can guide it to fly towards the platform and land on it. Two supports on the drone's bottom correspond to two electromagnets for positioning, and a magnetic charger corresponds to the charging position on the drone's bottom for charging. An electric drive mechanism rotates the protective cover, using a simple rotational drive to protect the drone during charging. This allows for automatic repair and charging of drones with low battery during power inspections, eliminating the need for manual charging and improving the efficiency of power inspections.

[0012] Preferably, it further includes:

[0013] A gravity sensor is mounted on the top of the platform;

[0014] When the gravity sensor is under pressure, the control unit controls the protective cover to close, the electromagnet to be energized and activated, and the magnetic charger to start charging.

[0015] After the drone lands on the platform, the gravity sensor can sense the drone's gravity, which causes the gravity sensor to be pressed. When the gravity sensor is pressed, the control unit controls the protective cover to close, the electromagnet to be energized and the magnetic charger to start charging.

[0016] Preferably, it further includes:

[0017] The control unit receives flight information from drones that enter the designated area, including remaining battery power, navigation route, and location information.

[0018] The control unit calculates the remaining flight distance H1 of the drone based on the remaining battery power.

[0019] The control unit calculates the remaining distance H2 of the UAV based on the navigation route and the location information;

[0020] The control unit substitutes the remaining distance H2 and the remaining flight distance H1 into the judgment formula H2≥H1. If the judgment formula is satisfied, the control unit compares the platform layout information from the input terminal with the navigation route information to obtain intermediate platform information. The intermediate platform information is the outdoor platform corresponding to the platform layout information located on the navigation route information.

[0021] The control unit sends the intermediate platform information to the drone;

[0022] Once the drone enters the designated area, i.e., within the coverage area of ​​the outdoor platform, it sends flight information to the control unit. The control unit receives this information and calculates the remaining flight distance H1 based on the remaining battery level. It then calculates the remaining distance H2 to the destination based on the navigation route and location. The remaining distances H1 and H2 are then compared using the condition H2≥H1. If the remaining distance H1 is less than the remaining distance H2, the drone cannot reach its destination and needs to be recharged en route. The control unit then compares the remaining distances H1 and H2 with the intermediate platform information on the navigation route. This information is sent to the drone, allowing it to quickly locate the nearest outdoor platform when its battery is low and reroute to recharge. This helps prevent the drone from crashing mid-flight due to insufficient battery power, thus avoiding the loss of inspection data.

[0023] Preferably, it further includes:

[0024] The control unit is also used to obtain the next monitoring point information based on the navigation route information and the platform layout information, wherein the next monitoring point information is the next platform information of the nearest outdoor platform on the UAV's navigation route;

[0025] The control unit calculates the next charging distance H3 based on the next platform information and the location information;

[0026] The control unit substitutes the next charging distance H3 and the remaining flight distance H1 into the judgment formula H3≥H1. If the judgment formula is satisfied, the control unit generates charging control information. The charging control information is used to control the drone to immediately change its flight path to go to the outdoor platform for charging.

[0027] The control unit sends the charging control information to the drone;

[0028] Based on navigation route information and platform layout information, the control unit can determine the location of the nearest next outdoor platform on the drone's flight path. Then, the control unit calculates the next charging distance H3 by shortening the distance between the next outdoor platform and the drone's current location. It then substitutes the next charging distance H3 and the remaining flight distance H1 into the condition H3≥H1, comparing the remaining flight distance H1 with the next charging distance H3. If the remaining flight distance H1 is less than the next charging distance H3, it means the drone cannot reach the next outdoor platform. In this case, the control unit immediately generates charging control information and sends it to the drone to force it to immediately change course and head to the outdoor platform for charging. This helps prevent situations where the drone is unable to reach the next charging platform due to insufficient power, leading to a crash mid-flight and loss of inspection information.

[0029] Preferably, it further includes:

[0030] The remaining flight distance H1 is the distance that the remaining battery power, after deducting the emergency power, can fly.

[0031] The emergency power supply is input from the input terminal of the control unit, and is typically 10%-20%.

[0032] The remaining flight distance H1 calculated by the control unit is the remaining power after subtracting the emergency power from the drone's existing power and the power consumption during the drone's flight. This helps ensure that the drone still has a small amount of power left after flying the remaining flight distance H1. On the one hand, it helps to avoid the situation where the drone's power consumption increases when flying against the wind, leading to inaccurate distance calculations. On the other hand, it helps to avoid the situation where the drone needs to fly to the next outdoor platform if the platform is damaged or occupied, resulting in the inability to charge in time. The emergency power is input into the control unit, which is set by the staff as needed, usually 10%-20%, and can be appropriately increased in strong winds.

[0033] Preferably, it further includes:

[0034] The control unit is also used to receive damage information of the drone entering the designated range, the damage information including no damage, partial damage, and severe damage;

[0035] When the damaged information is undamaged, the control unit does not perform any additional control.

[0036] When the damaged information is partially damaged, the control unit controls the drone to immediately change course to head towards the outdoor platform;

[0037] When the drone arrives at the outdoor platform, the control unit is also used to control the connected drone to back up inspection information;

[0038] During flight, the drone's self-check categorizes its condition as undamaged, partially damaged, or severely damaged. If it is undamaged, the drone is in normal working order, and the control unit does not perform any additional control. If it is partially damaged, the drone is still flying normally, but its arrival at the destination is uncertain. In this case, the control unit immediately changes the drone's course to the outdoor platform. Upon arrival at the platform, the drone backs up the inspection information collected during the inspection process. This backup information is temporarily stored on the outdoor platform. The drone then continues its flight to the destination. If the drone successfully reaches the destination, the backup information on the outdoor platform can be deleted. If it fails to reach the destination, staff can retrieve the backup information from the platform. This helps prevent the drone from crashing mid-flight due to insufficient power, thus avoiding the loss of inspection information.

[0039] Preferably, it further includes:

[0040] The control unit is also used to mark the drone when the partially damaged drone reaches the outdoor platform;

[0041] When the control unit obtains the marker arrival information, it controls the deletion of the corresponding inspection information backup. The marker arrival information is generated by the destination end and sent to the control unit after the UAV completes the information upload upon reaching the destination.

[0042] While the drone is backing up information on the outdoor platform, the control unit marks the drone. Subsequently, if the drone reaches the destination and uploads the inspection information, the destination will generate a marker arrival information and send the marker arrival information to the control unit. After receiving the marker arrival information, the control unit will delete the corresponding backed-up information, thereby reducing the memory usage of the outdoor platform.

[0043] Preferably, it further includes:

[0044] When the damaged information is severely damaged, the control unit is also used to control the UAV to immediately change course to go to the outdoor platform, and control the connected UAV to back up the inspection information;

[0045] The control unit is also used to extract the navigation route S1 corresponding to the severely damaged drone;

[0046] The control unit is also used to extract the navigation routes Sn of each UAV that enters the designated range;

[0047] The control unit compares the navigation route Sn with the navigation route S1 to find drones with the same navigation route and marks them. At the same time, it sends an emergency transfer control message to the marked drone. The emergency transfer control message is used to control the marked drone to immediately change course to go to the outdoor platform and receive the inspection information carried by the severely damaged drone.

[0048] When a drone is severely damaged and unable to continue long-distance flight, the control unit immediately changes its course to the outdoor platform and backs up the inspection information. The control unit also retrieves the navigation route S1 of the damaged drone and continuously monitors all drones within the outdoor platform's information range for their corresponding navigation routes Sn. Navigation routes S1 and Sn are compared to identify and mark drones with the same routes. The control unit then sends an emergency transfer control message to the marked drone, instructing it to immediately change course to the outdoor platform and receive the inspection information from the severely damaged drone. The marked drone then carries its own inspection information and the damaged drone's inspection information to the destination and uploads the information. Upon completion, the destination generates a marker arrival message and sends it to the control unit. The control unit then deletes the backed-up information upon receiving the marker arrival message, thus transmitting the inspection information. Meanwhile, the damaged drone awaits repair on the outdoor platform.

[0049] Preferably, it further includes:

[0050] When a severely damaged drone arrives at the outdoor platform, the control unit is also used to acquire the serial number information from the severely damaged drone and generate a warning message, which includes the serial number information and a warning message for alerting staff.

[0051] The control unit sends the warning information to the operating terminal;

[0052] When a severely damaged drone arrives at the outdoor platform, the control unit obtains the drone's serial number information and generates a warning message containing the serial number and warning information, which is then sent to the operator terminal. This allows the operator terminal to receive information about the drone's damage and identify the model of the damaged drone, thus enabling the operator terminal to quickly dispatch personnel for drone repair.

[0053] Preferably, it further includes:

[0054] The phrase "no damage" means that the drone did not suffer any damage.

[0055] The damage described refers to the fact that the drone was still able to fly normally after being impacted.

[0056] The severe damage refers to the drone remaining in flight after being impacted, with some parts damaged.

[0057] If a drone is struck and no major components are damaged during the self-test, but its ability to function normally cannot be guaranteed, it is considered partially damaged. If a drone is struck and major components are damaged during the self-test, but it is temporarily able to fly, it is considered severely damaged.

[0058] Compared with the prior art, the present invention has the following beneficial effects:

[0059] During power line inspections using drones, drones with low battery levels can be automatically repaired and recharged, eliminating the need for manual charging and improving the efficiency of power line inspections. Attached Figure Description

[0061] In the diagram: 1. Bracket; 2. Platform; 3. Electromagnet; 4. Magnetic charger; 5. Protective cover; 6. Control unit. Detailed Implementation

[0062] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0063] The figure shows an outdoor platform for power line inspection drone maintenance, including a support frame and:

[0064] The platform is fixed to the top of the support frame;

[0065] Two electromagnets are symmetrically fixedly installed on the top of the platform, with their tops flush with the top of the platform.

[0066] The magnetic charger is mounted on the top of the platform via a telescopic rod, which is used to push the magnetic charger to move vertically.

[0067] The protective cover is mounted on the top of the platform via an electric drive mechanism to rotate and switch between opening and closing.

[0068] The control unit is used to control the drones that enter the designated area to communicate, so as to exchange information based on the information of the drones and realize corresponding control.

[0069] In existing technologies, some drones may experience power shortages or crash due to impacts during inspections. When a drone is at risk of crashing, the inspection information stored on it may be lost. To avoid the leakage of important information, drones need to accurately transmit information to the destination to achieve information communication.

[0070] This embodiment of the invention can solve the above problems. The specific implementation is as follows: When the drone flies into the coverage area of ​​the outdoor platform, the control unit detects the drone and interacts with it to receive its flight information. If the drone's battery is low, the control unit can control the drone to fly towards the platform and land on it. Two brackets on the bottom of the drone correspond to two electromagnets for positioning. A magnetic charger corresponds to the charging position on the bottom of the drone for charging. An electric drive component drives the protective cover to rotate, using the simplest rotation drive to protect the drone during charging. Therefore, during drone power inspection, drones with low battery can be automatically inspected and charged, eliminating the need for manual charging and improving the efficiency of power inspection.

[0071] As an optional embodiment, it also includes:

[0072] Gravity sensor, mounted on top of the platform;

[0073] When the gravity sensor is under pressure, the control unit is used to control the protective cover to close and the electromagnet to be energized and the magnetic charger to be activated for charging;

[0074] After the drone lands on the platform, the gravity sensor can sense the drone's gravity, which causes the gravity sensor to be pressed. When the gravity sensor is pressed, the control unit controls the protective cover to close, the electromagnet to be energized and the magnetic charger to start charging.

[0075] As an optional embodiment, it also includes:

[0076] The control unit 6 receives flight information from drones that enter the designated range. The flight information includes remaining battery power, navigation route, and location information.

[0077] The control unit 6 calculates the remaining flight distance H1 of the drone based on the remaining battery power;

[0078] The control unit 6 calculates the remaining distance H2 of the UAV based on the navigation route and location information;

[0079] The control unit 6 substitutes the remaining distance H2 and the remaining flight distance H1 into the judgment formula H2≥H1. If the judgment formula is satisfied, the control unit 6 compares the platform layout information from the input terminal with the navigation route information to obtain the intermediate platform information. The intermediate platform information is the outdoor platform corresponding to the platform layout information on the navigation route information.

[0080] Control unit 6 sends intermediate platform information to the drone;

[0081] Once the drone enters the designated area, i.e., the coverage area of ​​the outdoor platform, it sends flight information to the control unit 6. The control unit 6 then receives this information and calculates the remaining flight distance H1 based on the remaining battery power. It also calculates the remaining distance H2 to the destination based on the navigation route and location. The remaining distance H1 and distance H2 are then compared to the equation H2≥H1. If the remaining distance H1 is less than the remaining distance H2, the drone cannot reach its destination and needs to be recharged during the journey. The control unit 6 then compares the intermediate platform information in the platform layout information with the navigation route information, finding an outdoor platform near the navigation route and sending this information to the drone. This allows the drone to quickly locate the nearest outdoor platform when its battery is low and change its route to recharge, thus preventing the drone from crashing mid-flight due to insufficient power and losing inspection information.

[0082] As an optional embodiment, it also includes:

[0083] Control unit 6 is also used to obtain the next monitoring point information based on navigation route information and platform layout information. The next monitoring point information is the next platform information of the outdoor platform that is closest to the UAV on the UAV's navigation route.

[0084] Control unit 6 calculates the next charging distance H3 based on the next platform information and location information;

[0085] The control unit 6 substitutes the next charging distance H3 and the remaining flight distance H1 into the judgment formula H3≥H1. If the judgment formula is satisfied, the control unit 6 generates charging control information. The charging control information is used to control the drone to immediately change its course to go to the outdoor platform for charging.

[0086] Control unit 6 sends charging control information to the drone;

[0087] Based on navigation route information and platform layout information, control unit 6 can determine the location of the nearest next outdoor platform on the drone's flight path. Then, control unit 6 calculates the next charging distance H3 by shortening the distance between the next outdoor platform and the drone's current position. It then substitutes the next charging distance H3 and the remaining flight distance H1 into the judgment formula H3≥H1, that is, it compares the remaining flight distance H1 and the next charging distance H3. If the remaining flight distance H1 is less than the next charging distance H3, it means that the drone cannot reach the next outdoor platform. At this time, control unit 6 immediately generates charging control information and sends it to the drone to force the drone to immediately change its flight path to the outdoor platform for charging. This helps to avoid the situation where the drone cannot reach the next charging platform when the outdoor platform is far away, resulting in the drone crashing midway due to insufficient power and the loss of inspection information.

[0088] As an optional embodiment, it also includes:

[0089] The remaining flight distance H1 is the distance that the remaining battery power can fly after deducting the emergency power.

[0090] Emergency power is input through the input terminal of control unit 6, typically 10%-20%;

[0091] The remaining flight distance H1 calculated by the control unit 6 is based on the remaining power after subtracting the emergency power from the existing power of the drone and the power consumption during the drone's flight. This ensures that the drone still has a small amount of power left after flying the remaining flight distance H1. On the one hand, this helps to avoid the situation where the drone's power consumption increases when flying against the wind, leading to inaccurate distance calculations. On the other hand, it helps to avoid the situation where the drone needs to fly to the next outdoor platform if the platform is damaged or occupied, resulting in the inability to charge in time. The emergency power is input into the control unit 6, which is set by the staff as needed, usually 10%-20%, and can be appropriately increased in strong winds.

[0092] As an optional embodiment, it also includes:

[0093] Control unit 6 is also used to receive damage information of drones entering the designated range, including no damage, partial damage, and severe damage;

[0094] If the information indicates no damage, control unit 6 will not perform any additional control.

[0095] When the damage information indicates partial damage, control unit 6 controls the drone to immediately change course and head towards the outdoor platform;

[0096] When the drone arrives at the outdoor platform, the control unit 6 is also used to control the connected drone to back up inspection information;

[0097] During flight, the drone's self-check categorizes its condition as undamaged, partially damaged, or severely damaged. If it is undamaged, meaning the drone is in normal working order, control unit 6 does not perform any additional control. If it is partially damaged, the drone is still in normal flight, but its arrival at the destination is uncertain. In this case, control unit 6 immediately changes the drone's flight path to the outdoor platform. Upon arrival at the outdoor platform, the drone backs up the inspection information collected during the inspection process. This backup information is temporarily stored on the outdoor platform. The drone then continues its flight to the destination. If the drone successfully reaches the destination, the backup information on the outdoor platform can be deleted. If it fails to reach the destination, staff can retrieve the backup information from the outdoor platform. This helps prevent the drone from crashing mid-flight due to insufficient power, thus avoiding the loss of inspection information.

[0098] As an optional embodiment, it also includes:

[0099] When the partially damaged drone reaches the outdoor platform, the control unit 6 is also used to mark the drone;

[0100] When the control unit 6 obtains the marker arrival information, it deletes the corresponding inspection information backup. The marker arrival information is generated by the destination end and sent to the control unit 6 after the UAV has completed the information upload upon reaching the destination.

[0101] While the drone is backing up information on the outdoor platform, the control unit 6 marks the drone. Subsequently, if the drone reaches the destination and uploads the inspection information, the destination will generate a mark arrival information and send the mark arrival information to the control unit 6. After receiving the mark arrival information, the control unit 6 will delete the corresponding backed-up information, thereby reducing the memory usage of the outdoor platform.

[0102] As an optional embodiment, it also includes:

[0103] When the damaged information is severely damaged, the control unit 6 is also used to control the drone to immediately change course to the outdoor platform and control the connected drone to back up the inspection information.

[0104] Control unit 6 is also used to extract the navigation route S1 of the corresponding severely damaged drone;

[0105] Control unit 6 is also used to extract the navigation routes Sn of each UAV that enters the designated range;

[0106] The control unit 6 compares the navigation route Sn with the navigation route S1, finds the drone with the same navigation route and marks it. At the same time, it sends an emergency transfer control message to the marked drone. The emergency transfer control message is used to control the marked drone to immediately change its course to go to the outdoor platform and receive the inspection information carried by the severely damaged drone.

[0107] When a drone is severely damaged and it is clear that it cannot continue long-distance flight, control unit 6 immediately changes its flight path to the outdoor platform and controls the connected drone to back up inspection information. The inspection information is backed up on the outdoor platform. At the same time, control unit 6 obtains the navigation route S1 of the damaged drone and obtains the corresponding drone's navigation route Sn from all drones within the outdoor platform's information range and continuously monitors all drones within the outdoor platform's information range. It compares navigation route S1 with navigation route Sn, finds drones with the same navigation route, and marks them. Then, control unit 6 sends an emergency transfer control message to the marked drone to control it to immediately change its flight path to the outdoor platform and receive the inspection information carried by the severely damaged drone. The marked drone then carries its own inspection information and the inspection information of the damaged drone to the destination and uploads the inspection information. After the upload is completed, the destination also generates a marked arrival information and sends it to control unit 6. After receiving the marked arrival information, control unit 6 deletes the corresponding backed-up information, thus realizing the transmission of inspection information. Meanwhile, the damaged drone waits for repair on the outdoor platform.

[0108] As an optional embodiment, it also includes:

[0109] When a severely damaged drone arrives at the outdoor platform, the control unit 6 is also used to obtain the serial number information from the severely damaged drone and generate a warning message, which includes the serial number information and a warning message for alerting the staff.

[0110] Control unit 6 sends the warning information to the operating terminal;

[0111] When a severely damaged drone arrives at the outdoor platform, the control unit 6 obtains the drone's serial number information and generates a warning message containing the serial number and warning information, which is then sent to the operator terminal. This allows the operator terminal to obtain information about the drone's damage and identify the model of the damaged drone, thus enabling the operator terminal to quickly dispatch personnel to repair the drone.

[0112] As an optional embodiment, it also includes:

[0113] No damage means the drone has not suffered any damage;

[0114] The damage was partial, meaning the drone was still able to fly normally after being impacted.

[0115] Severe damage means that the drone was still in flight after being impacted, and that some parts were damaged.

[0116] If a drone is struck and no major components are damaged during the self-test, but its ability to function normally cannot be guaranteed, it is considered partially damaged. If a drone is struck and major components are damaged during the self-test, but it is temporarily able to fly, it is considered severely damaged.

[0117] The working principle of this invention is as follows: When the drone flies into the coverage area of ​​the outdoor platform, the control unit 6 detects the drone and interacts with it to receive its flight information. If the drone's battery is low, the control unit can control the drone to fly towards the platform 2 and land on it. Two supports on the bottom of the drone correspond to two electromagnets 3 for positioning. A magnetic charger 4 corresponds to the charging position on the bottom of the drone for charging. An electric drive unit drives the protective cover 5 to rotate, using a simple rotational drive to protect the drone during charging. This allows for automatic repair and charging of drones with low battery during power inspections, eliminating the need for manual charging and improving the efficiency of power inspections.

[0118] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
