Description

Technical Field

[0001] The present invention relates to the field of patrol inspection technology, and in particular to a new energy power station management system based on user feedback. Background Art

[0002] At present, new energy power stations mainly use photovoltaic power generation and wind power generation. For photovoltaic power stations, multiple string photovoltaic power generation systems are usually arranged on the ground. This type of power station has a simple structure and low maintenance cost. However, when the sunlight conditions are poor, some components are prone to overheating, voltage is too low, and component output power is unstable. In order to ensure the safe and stable operation of new energy power stations, regular inspections are required. The common inspection method is for operation and maintenance personnel to carry professional inspection tools to each site for manual inspection. In this process, due to the lack of intelligent means and the subjectivity of manual inspections, it is easy to cause missed inspections or missed inspections. Therefore, the inspection work of new energy power stations is gradually combined with automation and intelligent technologies to form safer inspection technologies.

[0003] A Chinese patent document with publication number CN115018434A discloses a remote operation and maintenance management system for a new energy power station, including a data layer, a service layer, a business layer, and a display layer. It is connected to the monitoring system through an API interface to obtain data related to the operation and maintenance work, and all the operation and maintenance management work is managed online.

[0022] See also Figure 1 As shown, it is a structural schematic diagram of a new energy power station management system based on user feedback according to an embodiment of the present invention. The present invention provides a new energy power station management system based on user feedback, including: A user feedback module, which is connected to the user terminal and is used to receive feedback data submitted by the user, wherein the feedback data includes device operation data, and the device operation data includes image data and video data; A patrol monitoring module, which includes a number of intelligent patrol devices, and the patrol monitoring module is used to automatically collect patrol data, and the patrol data includes patrol route images; A data processing module connected to the inspection monitoring module, which is used to identify obstacles in the inspection route based on the inspection route image, determine the current inspection environment based on the real-time obstacle ratio, and determine abnormal conditions of the inspection route based on the current inspection environment; A data analysis module, which is connected to the user feedback module and the inspection monitoring module respectively, is used to classify and prioritize the feedback data, generate work orders, and determine whether to update the work orders based on abnormal conditions of the inspection routes.

[0023] The user feedback module in this embodiment is a mobile application that can record inspection data, upload pictures and videos, and submit feedback. The intelligent inspection equipment includes drones, ground robots and fixed monitoring equipment. The drone is equipped with a high-definition camera, a thermal imager, and an environmental sensor for automatic ground inspection; the robot is used for ground inspection and can carry various detection equipment, such as infrared cameras and vibration sensors; the fixed monitoring equipment is installed at the key position of the power station to continuously monitor environmental parameters and equipment status; a three-dimensional model is established for the inspection scene, and then the model is updated, and each component in the photovoltaic power station is regarded as an independent module. By classifying the modules, the new energy power station can quickly find the required components during the inspection. During the inspection process, it is necessary to obtain the relevant information of each new energy power station component from the database and input it into the corresponding module; each component has its own unique parameter information and related models; for example, for circular components, it can be modeled by the quaternion method; for square and rectangular components, the quaternion method can be used to establish its model; for triangular components, the Euler method or the quadrilateral method can be used to establish its model. When establishing an environmental model, some feature data and corresponding environmental parameters also need to be determined. During inspection, the connection relationship between different components can be identified to determine whether the components are operating normally. At the same time, the working status of each component can be determined by simulation analysis of the new energy power station components.

[0025] See also Figure 2 As shown, it is a structural diagram of a data processing module according to an embodiment of the present invention; Specifically, the data processing module includes an identification unit, an environment perception unit and an abnormality monitoring unit, wherein: The recognition unit is used to extract features from the inspection route image and match the environment model with the features to identify obstacles in the inspection route; The environment perception unit is used to determine the real-time obstacle ratio in the inspection route image, and determine the current inspection environment based on the real-time obstacle ratio; The abnormality monitoring unit is used to determine whether to mark the current detection point as an abnormal detection point based on the current inspection environment, and to determine the abnormal situation of the current inspection route according to the abnormal detection point.

[0026] See also Figure 3 As shown, it is a schematic diagram of the structure of the identification unit according to an embodiment of the present invention; Specifically, the recognition unit includes a modeling subunit, a feature extraction subunit, a feature matching subunit and a comparison subunit, wherein: The modeling subunit is used to generate a 3D environment model using a laser radar; The feature extraction subunit is used to extract features from the inspection route image to obtain a feature descriptor; The feature matching subunit is used to calculate the distance between feature descriptors, calculate the distance between each pair of feature descriptors, and select the feature descriptor with the smallest distance as the matching feature; The comparison subunit is used to compare the matched features with the geometric shapes of obstacles in the environment model to identify obstacles.

[0027] See also Figure 4 As shown, it is a schematic diagram of the structure of the environment perception unit according to an embodiment of the present invention; Specifically, the environment perception unit includes an acquisition subunit and a determination subunit, wherein: The acquisition subunit is used to calculate the percentage of the number of obstacle pixels in any of the inspection route images to the total number of pixels, and obtain the real-time obstacle ratio; The determination subunit determines the real-time obstacle ratio according to the standard obstacle ratio range, determines the current inspection environment as the first inspection environment according to the determination result, and determines the current inspection environment as the first inspection environment or the second inspection environment in combination with the image stability analysis result; The current inspection environment includes a first inspection environment and a second inspection environment.

[0028] The first inspection environment in this embodiment means that there are no obstacles, or even if there are some obstacles, the complexity of the background is low. Therefore, overall, the environmental information perception performance is strong, which can ensure the accurate positioning of the drone and reliable inspection path planning; the second inspection environment means that due to the large proportion of obstacles or the high complexity of the background, the scene perception match is low and the perception ability is poor.

[0029] Specifically, the determination subunit determines that the current inspection environment is the first inspection environment when the real-time obstacle ratio is less than or equal to the minimum value of the standard obstacle ratio range; When the real-time obstacle ratio is within the standard obstacle ratio range, the current inspection environment is determined in combination with the image stability analysis result; when the real-time obstacle ratio is greater than or equal to the maximum value of the standard obstacle ratio range, the current inspection environment is determined to be the second inspection environment; When the first analysis result is obtained, determining that the current inspection environment is the second inspection environment; When the second analysis result is obtained, it is determined that the current inspection environment is the first inspection environment.

[0030] In this embodiment, the standard obstacle ratio represents the threshold for determining that there are no obstacles in the inspection route image, that is, all visible areas are open and there are no objects blocking the line of sight. The standard obstacle ratio range is set to 0% to 90%.

[0031] When it is determined that the real-time obstacle ratio is less than or equal to the minimum value of the standard obstacle ratio range, it means that there are no obstacles in the current inspection route image. Since there are no obstacles, the background complexity is low, and it is a simple ground or single background feature. In this environment, it is easy to perceive and identify, which is suitable for drone inspection. When the real-time obstacle ratio is greater than or equal to the maximum value of the standard obstacle ratio range, it means that most areas are occupied by obstacles, indicating that there are a lot of objects in the environment, which will significantly affect the inspection path and perception ability of the drone. When the real-time obstacle ratio is within the standard obstacle ratio range, it means that there are some objects in the environment, which may affect the path planning and perception ability of the drone. The current inspection environment is determined by combining the background complexity in the inspection route image to improve the accuracy of understanding the inspection environment.

[0032] Specifically, the data processing module also includes a stability analysis unit, The stability analysis unit is used to perform stability analysis on the inspection route image to obtain a stability analysis result, which includes a first analysis result and a second analysis result.

[0033] Specifically, the stability analysis unit includes a collection subunit, a calculation subunit and a first analysis subunit, wherein: The acquisition subunit is used to obtain the current inspection route image and the previous inspection route image, taking the current inspection route image as the current frame and taking the previous inspection route image as the reference frame; The calculation subunit is used to track the pixel motion between two frames, and obtain the motion rate vector, the feature point and the pixel displacement change corresponding to the feature point; The first analysis subunit is used to analyze the pixel displacement variation to determine whether there is jitter and obtain a first analysis result.

[0034] Specifically, the stability analysis unit further includes a second analysis subunit and a third analysis subunit, wherein: The second analysis subunit is used to analyze the background complexity of the current inspection image; The third analysis subunit is used to determine the stability analysis result in combination with the background complexity when determining that there is no jitter; The first analysis subunit compares the standard displacement difference with the pixel displacement variation: If the pixel displacement change is less than or equal to the standard displacement difference, it is determined that there is no jitter; If the pixel displacement variation is greater than the standard displacement difference, it is determined that jitter exists, and a first analysis result is obtained; The second analysis subunit determines that the background complexity of the current inspection image is the first background complexity or the second background complexity; The third analysis subunit obtains a first analysis result when it is determined that there is no jitter and the background complexity of the current inspection image is the first background complexity, and obtains a second analysis result when it is determined that there is no jitter and the background complexity of the current inspection image is the second background complexity.

[0035] In this embodiment, a stability analysis is performed on the inspection route image to analyze the quality of the image and obtain a stability analysis result. The first analysis result indicates that the quality of the current inspection image is low, and the second analysis result indicates that the quality of the current inspection image is high. The first background complexity indicates high background complexity, and the second background complexity indicates low background complexity. The background complexity is determined by analyzing the features, textures, color changes and diversity of objects in the current inspection route image. An edge detection algorithm is used to evaluate the number and distribution of edges in the image, that is, Canny edge detection is used to detect edges in the image. The complexity of the background is reflected according to the density of the edge, the area within the edge and the distribution. The density of the edge is compared with the set density threshold. If the density of the edge is greater than or equal to the density threshold, the current background complexity is determined to be high background complexity. If the density of the edge is less than the density threshold, the area of ​​the area within the edge formed after edge detection is calculated. If the area is greater than or equal to the set area threshold, the current background complexity is determined to be high background complexity. If the area is less than The area threshold is set to analyze whether the edge distribution is concentrated or uniform. If it is concentrated, the current background complexity is determined to be high, and if it is uniform, the current background complexity is determined to be low. The ratio of edge pixels to the entire image is calculated to obtain the edge density. The density threshold is in the range of 0.05-0.1 and is adjusted according to the characteristics of the actual image. For example, in a complex urban environment, the density threshold is set to 0.1 or higher, while in a simple natural scene, it is sufficient to set it to 0.05. The area threshold is set to 5000 pixels and should be adjusted according to the resolution and characteristics of the image, and decreases as the resolution of the image decreases. For example, in a high-resolution image, the area threshold is set to 5000 pixels. By analyzing the connectivity and distribution pattern of the edges, it is determined whether the edges are concentrated in certain areas or uniformly distributed. The standard displacement difference represents the threshold for determining the displacement change between adjacent frames. If the displacement change exceeds this threshold, it is considered that jitter exists. The standard displacement difference is set to 10 pixels.

[0036] Specifically, the abnormality monitoring unit includes a marking subunit and a determining subunit, wherein: The marking subunit is used to mark the current detection point as an abnormal detection point when the current inspection environment is the second inspection environment; The detection points correspond one-to-one to the components of the new energy power station; The determination subunit is used to calculate the percentage of abnormal detection points to the total detection points, obtain the real-time abnormality ratio, compare the allowed abnormality ratio with the real-time abnormality ratio, and determine the abnormality of the inspection route based on the comparison result; Among them, when the real-time abnormality ratio is less than or equal to the allowed abnormality ratio, the inspection route is judged to be normal; when the real-time abnormality ratio is greater than the allowed abnormality ratio, the inspection route is judged to be abnormal.

[0037] The allowed abnormality ratio in this embodiment indicates the proportion of detection point abnormalities allowed in the inspection route. The detection point abnormality means that the corresponding scene perception matching ability is poor. The higher the calculated real-time abnormality ratio is, when it is determined that the real-time abnormality ratio is greater than the allowed abnormality ratio, it means that the path planning is insufficient and the work order needs to be updated.

[0038] Specifically, the data analysis module includes a work order generation unit and a work order update unit, wherein: The work order generating unit is used to classify user feedback according to feedback type, and prioritize feedback data according to the urgency of the feedback, and generate a number of work orders; The work order updating unit is used to update the inspection route corresponding to the work order.

[0039] In this embodiment, when it is determined that the real-time abnormality ratio is greater than the allowed abnormality ratio, a dynamic programming algorithm (such as RRT*) is used to recalculate the inspection path to update the inspection route corresponding to the work order.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
