Description

Technical Field

[0001] The present invention relates to the technical field of power inspection, and in particular to a power inspection system and method thereof. Background Art

[0002] Power facilities are popular in all walks of life, and related power facilities are often laid in complex working environments. Therefore, affected by environmental erosion, equipment aging, garbage hanging, and human damage, etc., wires or other equipment in power facilities will be damaged. If not detected and repaired in time, it will cause fires or power outages. Therefore, it is necessary to regularly inspect power facilities to detect in advance the wear, aging, and potential fault levels of power equipment such as transformers, transmission lines, switches, etc. For example, it can detect situations such as insulation breakage, poor contact, and local overheating of equipment, avoid power outages caused by sudden equipment failures, and ensure continuous power supply for residents' lives, industrial production, and key places such as hospitals and transportation hubs.

[0003] At present, when inspecting power facilities, in order to avoid harm to workers and facilitate detection, drones are generally used for inspection. When using drones for inspection, corresponding image acquisition devices are generally installed on the drones to collect images of power facilities on the route, and then the information is transmitted to ground personnel. The ground personnel will judge the state of the power facilities according to the images, and finally mark the corresponding power facilities to facilitate accurate positioning during subsequent maintenance. However, this drone inspection method has visual blind spots. Especially when inspecting wires with a relatively large diameter, the position information of the part facing away from the image acquisition device will be ignored due to the visual blind spots. If there are cracks or damages in the blind spots, it is not conducive to the continued use of the wires and will cause problems for subsequent use. And if the wires need to be detected from multiple angles, the angles need to be switched and multiple round trips are required for detection, which wastes time and increases the workload of workers and equipment, resulting in low efficiency.

During this process, the distance between the UAV body 1 and the wire can be detected by the distance sensor 33. The operator remotely controls the flight adjustment of the UAV body 1 according to the information uploaded by the distance sensor 33 in real time. Here, an automatic mode can be set. The system uses the distance sensor 33 to identify and judge the distance between the UAV body 1 and the wire, and then adjusts it automatically. Secondly, the infrared temperature sensor 32 can sense the temperature of the wire during detection, finally form a temperature signal, transmit it to the controller 34, and then upload it to the control system of the operator to identify the abnormal temperature state of the wire.

[0043] Next, operate the drone body 1 to fly along the wire laying direction. During the flight, the first image device 5 and the two second image devices 6 will collect images of various angles of the wire. This information is uploaded to the controller 34 and then transmitted to the operator's operating system via the controller 34. When processing the image information, the controller 34 can judge whether the state of this section of the wire is abnormal by comparing with past data, output a warning instruction according to the abnormal situation, and transmit it to the operator's operating system. Finally, the operator makes a judgment and operates. The controller 34 will mark the position of the wire where the abnormality occurs to facilitate finding the position during subsequent maintenance. In order to cope with the image collection of multiple wires, therefore, an angle adjustment mechanism 7 is provided to adjust the image collection end of the second image device 6 in terms of distance and deflection angle to avoid the generation of blind spots and perform image collection operations on the wire state at more angles.

8. The power inspection system according to claim 2, wherein An installation groove (29) is installed below the support plate (204). The image device I (5) is adapted to be installed in the installation groove (29). Bolts (30) for clamping and stabilizing the image device I (5) are provided on both sides of the installation groove (29); a suspension bracket (31) is further connected to the installation groove (29), and an infrared temperature sensor (32) and a distance sensor (33) are installed on the suspension bracket (31).

9. A power inspection system according to claim 8, characterized in that, The control system includes a controller (34). The input end of the controller (34) is connected to the output ends of the image acquisition module, the infrared temperature sensor (32), and the distance sensor (33). The image acquisition module, the infrared temperature sensor (32), and the distance sensor (33) respectively output image data, temperature information, and distance information. After the input end of the controller (34) receives the image data, temperature information, and distance information, it is transmitted to the operating system of the ground personnel; the controller (34) is electrically connected to the angle adjustment mechanism (7) and the drone main body (1).

10. A method for a power inspection system, which uses the power inspection system according to any one of claims 1-9, characterized in that: This method includes the following steps: Step 1: First, install the suspension (2) on the drone main body (1), then install the horizontal bracket (4) on the suspension (2), then install the image device I (5) and the two image devices II (6) on the suspension (2) and the angle adjustment mechanism (7) respectively. Finally, turn on the control system to connect and interact with the control system operated by the ground personnel. When installing the suspension (2), connect the wire between the controller (34) located on the suspension (2) and the drone main body (1), and use the power supply of the drone main body (1) to supply power to the controller (34). Step 2: Through remote operation, operate the UAV body (1) to take off and fly to the selected route. Then place the wire at a suitable position between the first image device (5) and the two second image devices (6). During this process, the distance between the UAV body (1) and the wire can be detected by the distance sensor (33). According to the information uploaded by the distance sensor (33) in real time, the operator remotely controls the flight adjustment of the UAV body (1). Here, an automatic mode can be set. The system uses the distance sensor (33) to identify and judge the distance between the UAV body (1) and the wire, and then adjusts it automatically. Secondly, the infrared temperature sensor (32) can sense the temperature of the wire during detection, and finally form a temperature signal, which is transmitted to the controller (34), and then uploaded to the control system of the operator to identify the abnormal temperature state of the wire; Step 3: Then operate the UAV body (1) to fly along the wire laying direction. During the flight, the first image device (5) and the two second image devices (6) will collect images of various angles of the wire. This information is uploaded to the controller (34) and then transmitted to the operator's operating system through the controller (34). When processing the image information, the controller (34) can judge whether the state of this section of the wire is abnormal by comparing with past data, output a warning instruction according to the abnormal situation, and transmit it to the operator's operating system. Finally, the operator makes a judgment and operation, and its controller (34) will mark the position of the wire where the abnormality occurs to facilitate finding the position during subsequent maintenance; Step 4: In order to handle the image collection of multiple wires, an angle adjustment mechanism (7) is set to adjust the image collection end of the second image device (6) in terms of far and near distance and deflection angle to avoid the generation of blind spots and perform image collection operations on the wire state at more angles.
