Without voltage testing, workers may mistakenly believe the line is safe and directly contact it, leading to electric shock accidents, serious personal injury, or even death. Therefore, voltage testing of power lines is the first line of defense for safe power operations and an indispensable part of power system operation and maintenance management.

[0040] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application.

[0041] Figure 1 This is a schematic diagram of the structure of the voltage detection device provided in the embodiments of this application;

[0042] Figure 2 A flowchart illustrating the UAV-based voltage detection method provided in this application embodiment;

[0043] Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0044] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] In power systems, voltage testing of power lines is a crucial step in ensuring the safety of workers and the normal operation of electrical equipment. Although power outage measures are usually implemented before operation, lines may still carry voltage or generate dangerous currents due to potential risks such as circuit breaker failure, misoperation, induced voltage, and reverse power transmission. Without voltage testing, workers may mistakenly believe the line is safe and directly contact it, leading to electric shock accidents, serious personal injury, or even death. Therefore, voltage testing of power lines is the first line of defense for safe electrical work and an indispensable part of power system operation, maintenance, and management.

[0047] In existing technologies, devices that use drones to test for voltage in power lines typically employ rigid probes that directly contact the conductors. The voltage detector is fixed to the drone via an insulating rod, with one end of the rod fixed to the drone and the other end fitted with the voltage detector. The voltage detector is then used to test for voltage in the power line.

[0048] However, existing voltage testing devices for power lines have several drawbacks. First, improper installation can cause the drone to become top-heavy and unstable during flight. Second, the impact force generated by rigid contact can easily cause the drone to deviate from its intended attitude, potentially leading to a crash and posing significant safety hazards to equipment and personnel. Furthermore, due to the arrangement of conductors in overhead lines, existing drone voltage testing devices can only detect vertically or horizontally arranged conductors individually, limiting their practical application. Finally, existing drone voltage testing devices cannot effectively determine whether the voltage detector is making reliable contact with the conductor, leading to false positives or false negatives and affecting the accuracy of the voltage testing results.

[0049] Based on this, this application proposes a voltage testing method based on unmanned aerial vehicles (UAVs). With the development of UAV technology, its flexibility and controllability in voltage testing operations have significant advantages over manual methods. Therefore, using a UAV equipped with a voltage detector for voltage testing operations may effectively improve the accuracy and safety of voltage testing. Furthermore, since voltage testing failures are easily caused by viewing angle differences during the voltage testing process of a single UAV, if a guiding UAV can be introduced for auxiliary positioning, thereby providing a third-person view for the voltage detector UAV, it can help operators more accurately grasp the relative position of the voltage detector UAV and the conductor, reducing the difficulty of UAV voltage testing operations and improving the efficiency and safety of voltage testing operations.

[0050] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] Figure 1 This is a schematic diagram of the structure of the voltage detection device provided in the embodiments of this application; as shown below. Figure 1 As shown, the device includes an electroscope body 101, a flexible thin rod 102, an angle adjustment mechanism 103, a touch component 104, and a communication module 105.

[0052] The voltage detector body 101 is mounted on the drone tripod and is used to test the voltage of the circuit to be tested when the flexible thin rod 102 comes into contact with the circuit to be tested.

[0053] It should be noted that in traditional voltage testing devices, the voltage detector is installed at the end of the insulating rod, which makes the center of gravity of the drone on the insulating rod, easily causing a top-heavy phenomenon, thus affecting flight stability. However, by shifting the center of gravity of the voltage detector of the drone to the bottom of the drone, the problem of top-heavyness can be eliminated, significantly improving flight stability and enabling the drone to fly more smoothly during voltage testing operations.

[0054] A flexible thin rod 102 is mounted on the drone's tripod and clamped thereby by an angle adjustment mechanism 103, serving to fix the contact component 104. The angle adjustment mechanism 103 is located at the tail end of the flexible thin rod 102 and is used to adjust the angle between the flexible thin rod 102 and the contact component 104. The angle adjustment range is 0° to 45°, allowing the voltage detector to adapt to various wire arrangements, whether vertical, horizontal, or other complex arrangements. Voltage detection can be achieved by adjusting the angle of the flexible thin rod 102, greatly improving the system's applicability. The contact component 104 is made of metal wire, directly connected to the voltage detector body via a wire. This metal wire is μ-shaped, 3mm in diameter, and has a spread angle of 45°. Between 60° and the μ-shaped structure, the difficulty of voltage testing for drones is reduced, making it easier for the voltage tester to contact the wires. When in contact with the wires, the flexible rod 102 can produce a bending deformation of ≤5°, which can effectively absorb collision energy and reduce the impact of impact on the drone. The flexible rod 102 is connected to the drone's landing gear, and one end of the flexible rod 102 is connected to the μ-shaped metal wire. The flexible rod 102 is made of composite carbon fiber material, which has excellent flexibility and fatigue resistance.

[0055] The communication module 105, located within the voltage detector body 101, is used for wireless communication with the ground receiver. Furthermore, to reduce data latency, it integrates long-range (LoRa) transmission technology, ensuring that voltage detection results can be transmitted quickly and accurately to the ground control terminal. Simultaneously, this communication module supports audible and visual warning functions; when abnormal voltage detection results are detected, it can promptly issue warning signals to remind operators to take appropriate measures.

[0056] This application provides a voltage detector, comprising: a voltage detector body, a flexible rod, an angle adjustment mechanism, a contact component, and a communication module. The voltage detector body is mounted on a drone tripod and is used to test the voltage of the circuit to be tested when the flexible contact component contacts the circuit. The flexible rod is also mounted on the drone tripod and held in place by the angle adjustment mechanism to secure the contact component. The angle adjustment mechanism consists of two clamps fixed to the tail end of the flexible rod, used to adjust the angle of the flexible rod and the contact component. The contact component is located at the top of the flexible rod and is electrically connected to the voltage detector body, extending the contact of the voltage detector. The communication module is located within the voltage detector body and is used for wireless communication with a ground receiver. This ensures reliable contact between the voltage detector and the conductor, and enables wireless transmission of the voltage detection signal.

[0057] Figure 2 A flowchart illustrating the UAV-based voltage detection method provided in this application embodiment; as follows: Figure 2 As shown, the method includes:

[0058] S201. Simultaneously send flight control commands to the first UAV and the second UAV, so that the first UAV and the second UAV fly to opposite sides of the power line to be tested.

[0059] It should be understood that once the voltage testing device is ready, flight control commands are simultaneously sent to the first UAV (i.e., the voltage tester) and the second UAV (i.e., the guide UAV) so that the first UAV and the second UAV fly to opposite sides of the line to be tested, in preparation for the subsequent voltage testing operation.

[0060] S202, Receive a first image sent by the second UAV, wherein the first image includes at least an image of the power line to be tested and an image of the first UAV.

[0061] It should be understood that the second drone uses its onboard image acquisition equipment to acquire images of the power line to be tested and the first image of the first drone, and sends them to the first drone. The first drone receives the first image sent by the second drone so that the first drone can gradually approach the other side of the power line to be tested.

[0062] It is understandable that by receiving the first image sent by the second UAV, data support can be provided for the positioning and attitude adjustment of the first UAV, thereby improving the accuracy of the contact operation.

[0063] S203. Based on the first image, send an adjustment control command to the first UAV to adjust the position of the first UAV relative to the line to be tested until the flexible contact component of the power testing device carried by the first UAV touches the line to be tested.

[0064] In one possible approach, firstly, based on the first UAV image and the power line image to be tested in the first image, the relative positional relationship between the first UAV and the power line to be tested is determined; then, based on the relative positional relationship, the attitude adjustment information and position adjustment information of the first UAV are determined; next, an adjustment control command is generated based on the attitude adjustment information and position adjustment information; finally, the adjustment control command is sent to the first UAV.

[0065] It should be understood that by acquiring an image containing the first UAV and the power line to be tested, computer vision algorithms (such as target detection, edge extraction, or depth estimation) can be used to identify the first UAV and the power line to be tested in the first image. Based on the image coordinates or spatial features of the two, combined with camera parameters, depth information, etc., the relative positional relationship between the first UAV and the power line to be tested can be calculated, including distance, angle deviation, and relative direction. Furthermore, based on the calculated relative positional information, the difference between the current attitude of the UAV and the ideal touch attitude is analyzed, and the required three-axis attitude angle adjustment values ​​(such as pitch angle, yaw angle, roll angle) and three-dimensional spatial displacement (forward and backward, left and right, up and down) are calculated to form a complete adjustment control command, which is then sent to the first UAV.

[0066] Understandably, the above methods enable dynamic adaptive adjustment of the attitude and position of the first UAV, improving the UAV's adaptability to multi-angle and multi-directional lines in complex power environments, effectively avoiding risks such as deviation and collision, and enhancing the stability and safety of touch actions.

[0067] S204, Receive the second image sent by the second drone.

[0068] It should be understood that when the flexible contact component of the voltage testing device carried by the first UAV touches the line to be tested, the second UAV sends a corresponding contact image, i.e., the second image, to the first UAV to determine whether the flexible contact component has deformed.

[0069] S205. After determining that the flexible touch component has deformed based on the second image, a voltage detection signal is sent to the voltage detection device of the first UAV so that the voltage detection device can perform voltage detection on the circuit to be tested and obtain the voltage detection result.

[0070] In one possible approach, the deformation process of the flexible touch component is determined based on the second image, and the specific steps are as follows:

[0071] First, the first shape of the flexible touch component in the second image is identified; then, the similarity between the first shape and a preset shape is determined; finally, when the similarity meets a preset threshold, it is determined that the flexible touch component has deformed.

[0072] It should be understood that once the flexible touch device comes into contact with the wire, the μ-shaped metal wire undergoes observable elastic deformation due to the force. Therefore, the first shape of the flexible touch component in the second image can be identified by image processing algorithms, or it can be identified by the naked eye. The specific identification method can be selected according to the specific situation, and this application embodiment does not impose specific limitations here. Then, the first shape is compared with the preset shape, i.e., the non-contact shape. If the degree of deformation exceeds the preset threshold (e.g., the shape curvature decreases by more than 50%), it is determined to be a valid contact, and it is determined that the flexible touch component has deformed. After that, a voltage detection signal is sent to the voltage detection device of the first UAV so that the voltage detection device can perform voltage detection on the circuit to be tested and obtain the voltage detection result.

[0073] S206. Receive the voltage testing results sent by the voltage testing device.

[0074] In one possible approach, after receiving the voltage testing result sent by the voltage testing device, a warning signal is issued when the voltage testing result indicates that the line to be tested is energized; wherein the warning signal is an audible and visual warning, and / or, the warning signal is a warning message.

[0075] It should be understood that the voltage testing device in the second UAV tests the voltage of the circuit to be tested. After obtaining the voltage test result, it is transmitted to the ground control terminal in real time through the built-in communication module. The ground control personnel can obtain whether the corresponding voltage test result is abnormal through audible and visual warning signals or warning information. When the voltage test result is abnormal, the corresponding measures are taken quickly.

[0076] Understandably, the above methods allow operators to obtain the voltage status of the line without having to get close, improving response speed, reducing safety hazards, and enhancing the practicality and emergency response capabilities of the voltage detection device.

[0077] It should also be noted that after completing the single-point test, by controlling the landing of the first drone, the operator adjusts the contact direction of the thin, flexible conductive rod according to the arrangement of the wires to be tested using the angle adjustment mechanism. After the adjustment is completed, the first drone takes off again, and the above-mentioned voltage testing operation method is repeated to test the wires with different arrangements until the voltage testing of all wires to be tested is completed.
