Description

Technical Field

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

[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in a power plant is a step-up substation, and its function is to step up the voltage of the electric energy generated by the generator and feed it into the high-voltage power grid. The substation needs to be inspected during operation to avoid affecting the normal operation of the substation. Most of the time, cameras are used to capture the locations where defects may occur, and then staff monitor the captured images to determine whether there are any defects.

[0003] At present, some substation inspection operations use drone technology for inspection. In order to ensure that the images used for image recognition meet the quality requirements, multiple images will be taken of the inspected electrical equipment, and then all the images will be transmitted to the system server. The staff will then monitor through the captured images. However, in the actual image capture process, it is easy for the image to be out of focus, resulting in blur, or because of the weather, the captured image is reflective or dark, resulting in unclear images, which will cause errors in the staff's judgment of image defects and affect the use effect. For this reason, we provide a substation inspection operation system and communication method to solve this problem. Summary of the invention

The image data feedback module is connected to the inspection communication end, the image multi-directional shooting module is connected to the image sorting module, the image sorting module is connected to the image analysis module, the image analysis module is connected to the image selection module, the image selection module is connected to the image high-definition processing module, and the image high-definition processing module is connected to the image data feedback module bracket data signal.

[0008] Furthermore, the inspection navigation end includes a signal transmission module connected to the inspection communication end, the signal transmission module is connected to the inspection task module through a data signal, the inspection route data module is connected to the UAV navigation route planning algorithm module through a data signal.

[0009] Furthermore, the signal transmission module is connected to the inspection obstacle error reporting module via a data signal, and the inspection obstacle error reporting module is connected to the drone inspection reset module via an electrical signal.

[0010] Furthermore, the image analysis module includes a fuzziness analysis module and a lightness analysis module connected to the image sorting module data signal, the fuzziness analysis module and the lightness analysis module are connected to the image pre-selection module through the data signal, and the image pre-selection module is connected to the image selection module.

[0011] Furthermore, the image selection module includes an image information recognition and analysis module, a patrol target image specimen module and a target image confirmation module, the image information recognition and analysis module is connected to the image pre-selection module by data signals, and the image information recognition and analysis module and the patrol target image specimen module are both connected to the target image confirmation module by data signals.

[0012] Furthermore, the inspection communication terminal includes a UAV wireless communication module connected to the inspection system communication control terminal, the signal transmission module and the image data feedback module by wireless signals, and the UAV wireless communication module is connected to the signal frequency detection module through data signals.

[0013] Furthermore, the UAV wireless communication module is connected to a signal anti-interference processing module via a data signal, and the signal anti-interference processing module is connected to a signal frequency target threshold module via a data signal.

[0014] The present invention also provides a communication method for a substation inspection operation system, comprising the following steps:

[0015] S1. First, start the power supply of the inspection system communication control terminal and the inspection navigation terminal, inspection monitoring terminal, and inspection communication terminal in the UAV, so that they can prepare for the inspection operation after starting;

[0016] S2, the inspection task data information of this time is transmitted to the signal transmission module through the wireless communication module of the drone through the inspection system communication control terminal, so that the signal transmission module feeds back the information to the inspection task module, thereby triggering the task target instruction of this time in the inspection task module, and then feeds back the task target instruction to the inspection route data module, and the inspection route data module feeds back the inspection route map information of the stored substation to the drone navigation route planning algorithm module, and then the drone navigation route planning algorithm module plans the optimal route according to the inspection route information, and then wirelessly controls the drone to perform inspection operations through the inspection system communication control terminal;

[0017] S3. When the drone is performing inspection operations, the camera and radar equipment in the drone detect the road conditions ahead. If an unexpected roadblock occurs and the drone cannot pass, the information is transmitted to the signal transmission module through the drone wireless communication module, and the signal transmission module feeds back the information to the inspection obstacle error reporting module, so that the inspection obstacle error reporting module feeds back the information to the drone inspection reset module, so that the drone performs reset movement, and feeds back the information to the drone wireless communication module through the signal transmission module, and then feeds back the information to the inspection system communication control terminal, and the inspection system communication control terminal issues an alarm, so that the staff goes to solve the problem;

[0018] S4. When the UAV performs normal inspection operations, the multi-directional image shooting module of the inspection monitoring terminal takes multiple photos of the electrical equipment from multiple angles and directions, and transmits the image data to the image sorting module at the same time. The blur analysis module and the light intensity analysis module in the image analysis module perform blur analysis and light intensity analysis on all the photos taken in the image sorting module, and feed the analyzed data results back to the image pre-selection module. The image pre-selection module filters the photos with blurry, double-image, reflective and dark images according to the analysis of the photo images by the blur analysis module and the light intensity analysis module, and pre-selects the remaining photos.

[0019] S5. The image information recognition and analysis module of the image selection module analyzes the information in the image of the photo pre-selected by the image pre-selection module, and feeds back the data results after the analysis to the target image confirmation module. At the same time, the inspection target image specimen module also feeds back the target image information of the electrical equipment inspected at this time to the target image confirmation module. The target image confirmation module compares the data results after the analysis of the actual image with the standard target image data information, thereby confirming the image of useful information, and selecting and confirming it. Subsequently, the selected and confirmed photo is processed by the image high-definition processing module for high-definition clarity. Finally, the image data feedback module uses the drone wireless communication module to transmit the photo image to the inspection system communication control terminal, so that the staff can monitor the captured image and judge whether there is a defect.

[0020] S6. When the drone is performing inspection operations, the signal frequency detection module detects the signal frequency in real time. When the deviation between the signal frequency and the signal frequency target value of the signal frequency target threshold module is greater than the set value, the signal anti-interference processing module performs appropriate electromagnetic interference resistance adjustment processing based on the deviation value data between the signal frequency target value provided by the signal frequency target threshold module and the actual signal frequency, so that the deviation value between the actual signal frequency and the target signal frequency is within the set value range, ensuring that the drone can take photos and images for normal inspection and transmission.

[0022] 1. The substation inspection operation system and communication method confirms the inspection target task through the inspection navigation terminal, and then the drone performs effective inspection operations according to the optimal inspection route planned by the inspection navigation terminal. When an unexpected roadblock occurs and the drone cannot pass, the inspection obstacle error reporting module is used to report error information. At the same time, by triggering the drone inspection reset module, the drone is reset and flies back and forth, so that the substation inspection can be continued after the roadblock problem is solved;

[0023] 2. The substation inspection operation system and communication method filters all the photos taken by the inspection monitoring terminal for blur, ghosting, reflection, and darkness, and analyzes and identifies effective information of all pre-selected photo images after filtering through the image selection module, and finally selects photos with effective information, and processes such photo images with high definition, so that the staff can directly monitor the images with useful information and high definition, so as to quickly judge whether the photographed electrical equipment has defects, effectively improving the efficiency of inspection monitoring and judgment, and improving the use effect.
