Description

Technical Field

[0021] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0022] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0023] This application presents a drone inspection system according to a first embodiment. Please refer to [link / reference]. Figure 1 The drone inspection system includes: a control terminal 10 and a drone 20; The control terminal 10 communicates wirelessly with the UAV 20. The drone 20 is used to send a real-time power signal to the control terminal 10 when it is in a preset parking area; The control terminal 10 is used to send a corresponding task pre-assignment signal to the drone 20 when it receives the remaining power corresponding to the real-time power signal and it is within one of the preset power ranges. The drone 20 is used to send a corresponding power correction signal back to the control terminal 10 when it receives the task pre-assignment signal; The control terminal 10 is also used to send a corresponding task allocation signal to the drone 20 when it receives the actual available power corresponding to the power correction signal being in another preset power range; The drone 20 is also used to fly to the corresponding work assignment area and perform the corresponding inspection task when it receives the task assignment signal.

[0024] It should be noted that in this embodiment, the pre-designated parking area refers to the area used for the unified placement of the drone swarm 20. As a preferred approach, the pre-designated parking area is located in the substation area of ​​the power system. The substation area contains a substation, and the substation has ample open space for parking the drone swarm 20. Furthermore, the substation is the main core of the entire power system, which is primarily a grid-structured power grid. From the inside out, the power grid can be mainly divided into three functional areas: "substation-transmission section-distribution network section". Geographically, the substation (pre-designated parking area) is the central hub of the power grid, i.e., the geometric center of the inspection range. It can also be considered that the work allocation area where the "substation" is located is closest to the pre-designated parking area, the work allocation area where the "distribution network section" is located is farthest from the pre-designated parking area, and the work allocation area where the "transmission section" is located is at a moderate distance from the pre-designated parking area. This design facilitates the deployment of the drone 20's inspection path.

[0025] As is readily understood, in this embodiment, the work allocation area refers to the operational area corresponding to the inspection task performed by the UAV 20. The inspection task can be set according to the needs of different work allocation areas. For example, the inspection task corresponding to the work allocation area where the "distribution network segment" is located can be "inspecting whether the outer surface of the meter box is damaged".

[0026] It should be understood that, in this embodiment, the inspection path of the drone 20 is "preset parking area - work allocation area - preset parking area". When the drone 20 has sufficient battery power, it needs to use the preset parking area as the starting and ending point, flying a round trip along the corresponding "substation - transmission section - distribution network section - transmission section - substation" route. However, due to limited charging speed and other reasons, the drone 20 located in the preset parking area does not always have enough battery power to support it flying a complete round trip along the route.

[0027] It should be noted that the control terminal 10 refers to the control center located at the substation. The drone 20 is equipped with a battery pack for energy storage and power supply, and also features wireless communication, flight, navigation, and inspection functions, enabling it to perform inspection operations in the corresponding area. The drone 20 and the control terminal 10 can communicate wirelessly via 4G / 5G technology or a dedicated wireless communication protocol. In this embodiment, the real-time power signal is an electromagnetic wave signal used to characterize the drone 20's current remaining power. When the drone 20 is in a preset parking area, it can periodically check the battery status of its internal energy storage battery pack, including the percentage of remaining battery power and battery health status, and convert this information into a corresponding real-time power signal, which is then wirelessly transmitted to the control terminal 10.

[0028] It is easy to understand that a preset power range is a pre-set numerical interval used to describe the remaining power percentage. Multiple preset power ranges can be used to divide the power range from 0% to 100%. For example, the power range of 80%-100% can be defined as the high power range, and 30%-50% as the low power range. Therefore, multiple preset power ranges can exist in this embodiment. In this embodiment, when the control terminal 10 receives the real-time power signal, it can compare and match the current remaining power of the drone 20 with each preset power range to determine whether the current remaining power of the drone 20 is low or high. Based on the current remaining power status of the drone 20, the control terminal 10 pre-assigns inspection tasks corresponding to the flight distance of the drone 20. Specifically, a drone 20 with low power will be pre-assigned a short-distance inspection task (such as inspecting a certain area of ​​a substation), while a drone 20 with high power will be pre-assigned a long-distance inspection task (such as inspecting a certain area of ​​a distribution network segment). Subsequently, the control terminal 10 generates a corresponding task pre-assignment signal based on the task type, geographical coordinates of the work assignment area, estimated task execution time, and other relevant information of the pre-assigned inspection task, and transmits the task pre-assignment signal to the corresponding UAV 20.

[0029] It should be noted that the power consumption of the drone 20 is mainly for its flight and inspection functions. Actual available power can be understood as the safe power level that ensures the drone 20 can complete a preset inspection path without crashing, or as the necessary power level to maintain basic flight functions. In this embodiment, when the drone 20 receives the corresponding task pre-assignment signal, it will perform a more precise power assessment, considering factors such as remaining power, battery health, estimated flight distance, and load (the required inspection functions), to determine the actual available power level when flying to the pre-assigned work area (for example, when performing a high-power-consuming inspection function, the actual available power level is set to 70% of the current remaining power, with a 30% downward adjustment defaulting to the maximum power consumed in performing the inspection task), and generates a corresponding power correction signal to the control terminal 10.

[0030] In this embodiment, it is easy to understand that after receiving the power correction signal, the control terminal 10 will reassess the task allocation based on the actual available power reported by the drone 20. The control terminal 10 will re-compare and match the actual available power with each preset power range. If the actual available power does not meet all task requirements, the control terminal 10 will not send a task allocation signal to the drone 20, meaning the drone 20 will not be assigned any inspection tasks. If the actual available power meets a certain task requirement, the control terminal 10 can generate a corresponding task allocation signal based on the task type corresponding to the reassigned inspection task, the geographical coordinates of the work allocation area, the estimated task execution time, and other relevant information, and transmit the task allocation signal to the corresponding drone 20. The drone 20 will then fly along the designated inspection path to the specific work allocation area and perform the specific inspection task according to the finally received task allocation signal. This design makes the inspection task allocation of the drone 20 more reasonable and greatly reduces the probability of the drone 20 crashing on the inspection path due to insufficient power.

[0031] It is worth noting that in this embodiment, the control terminal 10 can communicate with multiple drones 20 and complete the task allocation for these drones 20. When allocating tasks to multiple drones 20, the actual available power of the same drone 20 may simultaneously meet multiple different task requirements. In this case, the control terminal 10 will prioritize assigning inspection tasks with higher power consumption to drones 20 with higher actual available power, and assigning inspection tasks with lower power consumption to drones 20 with lower actual available power. This design can further reduce the probability of drones 20 crashing on the inspection path due to insufficient power in scenarios where a group of drones 20 is being inspected.

[0032] This application provides a drone inspection system. In this system, when a drone is parked in a preset parking area, it transmits a real-time battery level signal, representing its remaining battery power, to a control terminal. The control terminal can pre-allocate tasks based on the drone's remaining battery power. While pre-allocating tasks, the drone sends a battery level correction signal, representing its actual available battery power for performing the pre-allocated task, back to the control terminal. The control terminal then re-allocates tasks based on the drone's actual available battery power. After task allocation, the drone flies to the corresponding assigned work area and performs the corresponding inspection task. Based on this system, tasks can be allocated to drones more rationally based on the current remaining battery power and inspection requirements, ensuring that the drone can complete the assigned task before its battery runs out.

[0033] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 The drone 20 includes: a battery management module 21, a power consumption prediction module 22, an inspection operation module 23, a first wireless communication module 24, and a first controller 25; The first controller 25 is connected to the first wireless communication module 24, the inspection operation module 23, the power consumption prediction module 22, and the battery management module 21, respectively. The battery management module 21 is used to collect the remaining power of the internal battery pack and send the corresponding power collection signal to the first controller 25. The first controller 25 is used to send the corresponding real-time power signal to the control terminal 10 through the first wireless communication module 24 when it receives the power acquisition signal; The first controller 25 is also configured to receive the task pre-allocation signal through the first wireless communication module 24 and send a corresponding prediction signal to the power consumption prediction module 22; The power consumption prediction module 22 is used to predict the power consumption of the inspection operation module 23 when it receives the prediction signal, and to feed back the corresponding power consumption prediction signal to the first controller 25. The first controller 25 is further configured to send a corresponding power correction signal to the control terminal 10 via the first wireless communication module 24 when it receives the power acquisition signal and the power consumption prediction signal.

[0034] It should be noted that the battery management module 21 is also connected to various functional modules inside the drone 20 to provide power to these modules, although their connection relationship is not shown in the figure. In this embodiment, the battery management module 21 is equipped with a battery pack for energy storage and power supply, and can collect the remaining power of the battery pack in real time and send the corresponding power acquisition signal to the first controller 25. When the first controller 25 receives the power acquisition signal, it sends the corresponding real-time power signal to the control terminal 10 through the first wireless communication module 24, enabling the control terminal 10 to promptly grasp the power status of the drone 20.

[0035] It is easy to understand that the inspection operation module 23 has flight and inspection task execution functions, and is controlled by the first controller 25. The power consumption prediction module 22 has a storage function, with a built-in mapping table between various inspection task execution functions and their respective power consumption ratios. In this embodiment, after receiving the task pre-allocation signal through the first wireless communication module 24, the first controller 25 can send a corresponding prediction signal to the power consumption prediction module 22 to trigger it to work. When the power consumption prediction module 22 receives the prediction signal, it can determine the inspection task that needs to be executed, generate a corresponding power consumption prediction signal by reading the table, predict the power consumption of the inspection operation module 23 during the execution of the pre-allocated task, and feed the power consumption prediction signal back to the first controller 25. When the first controller 25 receives the power consumption prediction signal, it corrects the remaining power and other information corresponding to the received real-time power signal to obtain the actual available power and other relevant information, converts it into a corresponding power correction signal, and then sends it to the control terminal 10 through the first communication module.

[0036] It is worth noting that in this embodiment, the power consumption of the drone 20 is also related to flight consumption and the execution time of the inspection task. Therefore, the mapping relationship table between the above-mentioned various inspection task execution functions and their respective power consumption ratios also includes flight parameters, time parameters, etc.

[0037] Furthermore, in this embodiment, the first controller 25 is also used to send a corresponding inspection control signal to the inspection operation module 23 when it receives the task allocation signal, so as to fly to the work allocation area and execute the inspection task.

[0038] It should be noted that the inspection control signal refers to the control signal used to control the inspection operation module 23 to perform flight and inspection task execution functions, including flight control signals and task execution control signals. In this embodiment, the inspection operation module 23 includes a flight drive unit 231 and a task execution unit 232. The flight drive unit 231 is used to implement the flight function when it receives the flight control signal; the task execution unit 232 is used to implement the inspection task execution function when it receives the task execution control signal. For the flight function, the inspection control signal contains relevant information such as flight altitude, flight speed, flight direction, and geographical coordinates of the work allocation area, which enables the UAV 20 to fly to the finally assigned work allocation area. For the inspection task execution function, the inspection control signal contains relevant information for initiating the execution of a specific inspection task, which can automatically trigger the inspection operation module 23 to execute the corresponding inspection task when it reaches the corresponding work allocation area.

[0039] It is easy to understand that, in this embodiment, in order to ensure the accuracy of the actual available power calculation, parameters that affect power consumption, such as flight speed and flight altitude, are usually set to fixed values. For example, the flight speed can be the median value within the adjustable range (e.g., 3m / s), and the flight altitude can be set to a fixed safe altitude higher than the inspection object (e.g., 5m).

[0040] Furthermore, in this embodiment, the task execution control signal includes a first task execution signal, and the task execution unit 232 includes: an infrared thermal imaging detection unit; The infrared thermal imaging detection unit is connected to the first controller 25; The infrared thermal imaging detection unit is used to detect the temperature of each circuit breaker in the work allocation area when it receives the first task execution signal.

[0041] It should be noted that in this embodiment, the work allocation area can be the substation area, the task execution control signal includes the first task execution signal, and the task execution unit 232 includes an infrared thermal imaging detection unit.

[0042] It is easy to understand that substations contain a large number of circuit breakers. In this embodiment, when the infrared thermal imaging detection unit receives the first task execution signal, it detects the temperature of each circuit breaker within the substation area. This enables the UAV 20 to promptly detect abnormal circuit breaker temperatures, preventing power equipment from malfunctioning due to overheating.

[0043] Furthermore, in this embodiment, the task execution control signal includes a second task execution signal, and the task execution unit 232 includes a laser measurement unit; The laser measurement unit is connected to the first controller 25; The laser measurement unit is used to detect the distance between each section of the power transmission line and surrounding obstacles within the work allocation area when it receives the second task execution signal.

[0044] It should be noted that in this embodiment, the work allocation area can be the power transmission section area, the task execution control signal includes the second task execution signal, and the task execution unit 232 includes a laser measurement unit.

[0045] It is easy to understand that a large number of power transmission lines are installed within the transmission section. In this embodiment, when the laser measurement unit receives the second task execution signal, it measures the distance between each section of the power transmission line and surrounding obstacles. In this way, the UAV 20 can monitor the safe distance between the power transmission lines and the surrounding environment, avoiding safety hazards caused by insufficient distance.

[0046] Furthermore, in this embodiment, the task execution control signal includes a third task execution signal, and the task execution unit 232 includes: a visual acquisition unit; The visual acquisition unit is connected to the first controller 25; The visual acquisition unit is used to acquire external images of each meter box within the work allocation area when it receives the third task execution signal.

[0047] It should be noted that in this embodiment, the work allocation area can be the distribution network segment area, the task execution control signal includes the third task execution signal, and the task execution unit 232 includes a visual acquisition unit.

[0048] It is easy to understand that a large number of meter boxes are located within the distribution network segment. In this embodiment, when the visual acquisition unit receives the third task execution signal, it acquires external images of each meter box within the distribution network segment. This enables the UAV 20 to obtain the external condition of the meter boxes and check for damage, corrosion, or other abnormalities.

[0049] It is worth noting that in this embodiment, in other work allocation areas outside the distribution network segment area, the control terminal 10 can actively send a corresponding third task execution signal to trigger the visual acquisition unit to actively turn on, thereby transmitting the acquired images of the surrounding environment back to the control terminal 10.

[0050] Furthermore, in this embodiment, the drone 20 also includes a positioning module 26; The positioning module 26 is connected to the first controller 25; The positioning module 26 is used to send a real-time positioning signal to the first controller 25; The first controller 25 is used to send the real-time power signal to the control terminal 10 through the first wireless communication module 24 when it receives the real-time positioning signal corresponding to the preset parking area and receives the power acquisition signal.

[0051] It should be noted that in this embodiment, the drone 20 also includes a positioning module 26. The positioning module 26 sends a real-time positioning signal to the first controller 25, enabling the first controller 25 to monitor the location information of the drone 20 in real time. Upon receiving the real-time positioning signal, the first controller 25 determines its current real-time location. When the drone 20 determines that its current real-time location is within a preset parking area and receives a power acquisition signal, it sends a real-time power signal to the control terminal 10 via the first wireless communication module 24. This allows the control terminal 10 to obtain the remaining power information of the drone 20 after it returns to the parking area, facilitating the arrangement of charging and subsequent task allocation.

[0052] It is worth noting that in this embodiment, the first controller 25 can also determine its own real-time position and the position of the destination through the positioning module 26, and adjust the flight direction of the flight drive unit 231 accordingly, so as to ensure that the UAV 20 can accurately fly to the corresponding work assignment area.

[0053] Based on the first and / or second embodiments of this application, in the third embodiment of this application, the content that is the same as or similar to that in embodiments one and two above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 In this embodiment, the control terminal 10 includes: a second controller 11 and a second wireless communication module 12; The second controller 11 is connected to the second wireless communication module 12; The second wireless communication module 12 is used to communicate wirelessly with the drone 20; The second controller 11 is used to send the task pre-assignment signal to the drone 20 through the second wireless communication module 12 when it receives the real-time power signal; The second controller 11 is also configured to send the task allocation signal to the drone 20 via the second wireless communication module 12 when it receives the power correction signal.

[0054] It is readily understood that in this embodiment, the second controller 11 has data processing capabilities, enabling it to receive and process signals from the drone 20 and generate corresponding control commands based on the received signals. The second controller 11 employs a microprocessor design, with built-in memory for storing control programs and temporary data. The second controller 11 has multiple input / output interfaces, including a communication interface for connecting to the second wireless communication module 12. The second wireless communication module 12 utilizes radio frequency technology, supports multiple communication protocols, and ensures stable signal transmission and reception with the drone 20.

[0055] In specific implementation, the second controller 11 can generate a corresponding task pre-assignment signal upon receiving a real-time power signal; the second controller 11 can also generate a corresponding task assignment signal upon receiving a power correction signal. The second wireless communication module 12 is used to wirelessly transmit the real-time power signal and the power correction signal from the drone 20 to the second controller 11, or to wirelessly transmit the task pre-assignment signal and the task assignment signal from the second controller 11 to the drone 20. The functions of the above signals have been described in detail above and will not be repeated here.

[0056] Furthermore, in this embodiment, the control terminal 10 further includes a charging module 13; The first end of the charging module 13 is connected to the substation, the second end of the charging module 13 is connected to the second controller 11, and the third end of the charging module 13 is used to connect to the drone 20. The second controller 11 is used to activate the charging module 13 upon receiving the real-time power signal; The charging module 13 is used to transmit the electrical energy provided by the substation to the drone 20 to charge the drone 20.

[0057] It should be noted that, in this embodiment, the control terminal 10 also includes a charging module 13 located in a preset parking area. When activated, the charging module 13 can convert the AC power provided by the substation into DC power suitable for charging the UAV 20's battery, and has overvoltage protection, overcurrent protection, and short-circuit protection functions. The switching of the charging module 13 is controlled by the second controller 11. The second controller 11 will only activate the charging circuit of the charging module 13 when it receives a real-time power signal, or when the UAV 20 is parked in the preset parking area and connected to the charging module 13, thus charging the UAV 20 using the power provided by the substation.

[0058] It is worth noting that in this embodiment, the charging module 13 can also be designed with an additional always-on charging circuit, so that the power provided by the substation can be used to power the control terminal 10.

[0059] Furthermore, in this embodiment, the control terminal 10 is also equipped with a display module 14 and an operation module 15. Operators can use the display module 14 to view the real-time status and charging status of the drone 20 and perform necessary manual interventions. Specifically, the display module 14 can be a display screen capable of showing information such as the drone 20's battery level, location, and task execution status; while the operation module 15 can be an operation panel with several buttons, allowing operators to manually generate specific signals to adjust charging parameters and task allocation.

[0060] Furthermore, in this embodiment, the control terminal 10 also has a storage module 16, which can record the charging history, task execution status and power change trend of the drone 20, providing data support for the management and maintenance of the drone 20.

[0061] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent scope of this application.
