Description

Technical Field

[0001] The present invention relates to the technical field of new energy photovoltaic engineering construction, and in particular to an EPCO new energy photovoltaic engineering construction management method. Background Art

[0002] With the global emphasis on renewable energy, the scale of the photovoltaic power generation market continues to expand, and the prospects for new energy photovoltaic power stations are very broad. This is mainly due to factors such as global demand growth, technological progress and policy support. At the same time, the management methods of photovoltaic power station construction have also been further improved and innovated. At the same time, with the reform of the organization and implementation methods of engineering construction projects, the EPC engineering general contracting management model has become a development trend of project management. So far, nearly half of the engineering projects in the construction market of developed countries have adopted the EPC engineering general contracting method, and my country's research on the EPC general contracting model has also been in an accelerated development stage. EPC general contracting refers to the general contracting enterprise of the engineering project, which undertakes the whole process of design, procurement, construction, trial operation and other services of the engineering project in accordance with the contract agreement, and is fully responsible for the quality, safety, construction period and cost of the contracted project, and delivers the project with conditions for use to the owner. EPC general contracting management is a key link in project implementation, which directly affects the quality, progress and cost of the project and even the later operation and maintenance. However, the complexity of EPC general contracting management has also become a bottleneck restricting the realization of the benefits of the EPC model. Although the EPC model covers multiple engineering management stages such as design, procurement, and construction, the EPC model lacks effective connection with operation and maintenance, which separates the guiding and regulatory role of operation and maintenance requirements in design, procurement, and construction.

[0003] At present, the practice of the EPC model of photovoltaic engineering projects includes at least the following three problems: 1) Incomplete information collection: The traditional new energy photovoltaic project construction management method uses motion devices to cooperate with photovoltaic panel components to complete the photovoltaic panels in different states. Designers can only find problems and analyze and deal with them by observing the different states of photovoltaic panels. It is impossible to conduct comprehensive analysis and information collection of photovoltaic power generation projects through visual means, and it is impossible to find problems in time and optimize construction plans; 2) Real-time monitoring and analysis cannot be performed. The traditional new energy photovoltaic project construction management method uses a control device to send commands to a motion device to achieve different light intensities of sunlight on the photovoltaic panels. However, this process lacks an operation and maintenance phase and cannot be monitored and analyzed in real time on site, resulting in problems such as irregular operations and substandard construction quality. 3) Poor applicability: Traditional new energy photovoltaic project construction management methods mainly use control devices, motion devices and photovoltaic panel components to control the sunlight shining on the photovoltaic panels, but can only control the intensity of sunlight on the photovoltaic panels, and cannot solve and optimize other problems existing in photovoltaic power generation projects. Summary of the invention

[0004] In view of the above three problems, the purpose of the present invention is to propose an EPCO new energy photovoltaic project construction management method. Based on the EPCO photovoltaic project construction management model, by utilizing drone survey technology, model management platform, remote command and dispatch system, real-scene acceptance system and shared operation and maintenance system, the problems existing in photovoltaic project construction, such as poor connection between design and construction, lack of guarantee of construction progress, substandard construction quality, low efficiency of operation and maintenance management, are overcome. The development bottleneck of the EPC photovoltaic project construction management general contracting model is unblocked, good economic, management and ecological benefits are achieved, and it has extremely strong promotion value.

[0005] This is achieved through the following technical solutions: A method for managing the construction of an EPCO new energy photovoltaic project, the method comprising the following steps: S1, controlling a drone to shoot a target area to obtain multiple image data of the target area; processing the multiple image data, including: eliminating lens distortion, correcting rotated images and removing image noise; S2, importing the processed multiple image data into a model synthesis software to obtain a three-dimensional model of a photovoltaic project construction area; then importing the processed multiple image data and the three-dimensional model of the construction area into a modeling software, adjusting the picture details of the three-dimensional model of the construction area according to the multiple image data, and exporting the adjusted three-dimensional model of the construction area in an OBJ format file; then, through real-scene modeling technology, importing the OBJ format file of the three-dimensional model of the construction area, the multiple image data shot by the drone and the design data into a model management platform to obtain a real-scene model of the construction area; S3, observing the terrain of the construction area through the real-scene model of the construction area, and using the real-scene model of the construction area to simulate the impact of real weather on photovoltaic power stations under different climates, And formulate a construction plan based on the results of observation and simulation; then order the materials required for construction through the construction plan, enter the order into the smart warehouse system, and track the order status in real time; S4, carry out construction according to the construction plan. During the construction process, workers wear smart helmets to reflect the real-time status of the workers on the large screen of the command center. At the same time, the AI ​​recognition function of the smart helmets is used to analyze the behavior of the workers, and the daily wages are paid according to the effective time of the smart helmets every day; S5. After the construction is completed, the multiple image data taken by the drone are imported into the VR panoramic production software, and the VR virtual scene of the construction area is obtained through editing and synthesis operations; at the same time, the VR virtual scene of the construction area is uploaded to the cloud platform, and the VR virtual scene is displayed and shared through web pages and mobile devices; S6. Based on the VR virtual scene of the construction area, the owner side observes the real-time operation status and power generation of the photovoltaic power station through the monitoring system attached to the shared operation and maintenance system, and the contractor side views the distribution, operation health and power generation of the built photovoltaic power stations through the shared operation and maintenance system.

[0006] The present invention is based on the EPCO photovoltaic engineering construction management model. By utilizing drone survey technology, model management platform, remote command and dispatch system, real-scene acceptance system and shared operation and maintenance system, it overcomes the problems of poor connection between design and construction, unguaranteed construction progress, substandard construction quality, low operation and maintenance management efficiency, etc. in photovoltaic engineering construction. In addition, project-related personnel can guide and adjust the construction site in real time, greatly improving the construction efficiency of photovoltaic power station construction.

[0007] Preferably, in step S2, the detail optimization tool in the modeling software is used to adjust the picture details of the three-dimensional model of the construction area, and the picture detail adjustment content includes: adjusting the viewing angle and display mode of the model, adjusting the texture and color of the model, and repairing the broken surface and wrong edges of the model. By adjusting the picture details of the three-dimensional model of the construction area, the accuracy of the three-dimensional model and the overall visual effect of the three-dimensional model are improved, so that the three-dimensional model of the construction area is closer to the real scene of the photovoltaic power station construction area.

[0008] Preferably, in step S2, the real scene modeling technology is used to adjust the tilt angle and wall gap of the three-dimensional model of the construction area according to the structural characteristics of the construction area. Through the real scene modeling technology, the three-dimensional model of the construction area can be more closely fitted, and a high-precision real scene model of the construction area can be obtained.

[0009] Preferably, in step S2, the design data includes: the actual construction plan data of the photovoltaic power station and the power generation related data of the photovoltaic power station, wherein the power generation related data includes: the data of the inverter, the electric meter and the key nodes in the distribution room. The model management platform makes the construction data of the real-life model of the construction area consistent with the actual construction data of the photovoltaic power station through the design data, and the obtained real-life model of the construction area can more realistically reflect the operating status of the photovoltaic power station.

[0010] Preferably, in step S4, the smart helmet worn by the worker is connected to the remote command and dispatch system, and the AI ​​recognition function of the smart helmet is used to reflect the worker's behavior on the big screen in real time through the remote command and dispatch system, and the worker's behavior is guided and adjusted in real time. The smart helmet connected to the remote command and dispatch system can monitor and guide the construction site in real time, dynamically coordinate human and material resources, improve work efficiency, and ensure construction quality.

[0013] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] like Figure 1 As shown, it is a flow chart of an EPCO new energy photovoltaic project construction management method. First, the target area is surveyed by controlling the drone to obtain multiple image data of the target area; then, the multiple image data taken by the drone and the model management platform are used to construct a real-life model of the construction area; then, the construction area is observed and simulated through the real-life model of the construction area, and a construction plan is formulated according to the results of the observation and simulation, and the order status of construction materials is tracked in real time; secondly, the worker behavior is guided and adjusted through the remote command and dispatch system; then, the VR virtual scene of the construction area is obtained by operating the real-life acceptance system, and the VR virtual scene of the construction area is uploaded to the cloud platform for display and sharing; finally, project-related personnel can observe the distribution, operation status and power generation of photovoltaic power stations through the shared operation and maintenance system. The present invention is based on the EPCO photovoltaic project construction management mode, overcomes the problems of low work efficiency, unguaranteed construction progress and substandard construction quality in photovoltaic project construction, and improves the construction efficiency of photovoltaic power station construction.

[0015] The method specifically comprises the following steps: S1. Select a suitable drone and configure a high-resolution camera according to the shooting requirements, and debug the parameters of the high-resolution camera, including focal length and exposure; then control the drone to shoot the target area, obtain multiple image data of the target area, and then process the multiple image data, including eliminating lens distortion, correcting rotated images, and removing image noise; among them, the lens-distorted image is manually corrected by selecting manual correction in the lens correction in the high-resolution camera, adjusting the distortion of the image, and further correcting the distortion of the image; for the rotated image, use the rotation image correction software, upload the rotated image to the rotation image correction software, select a suitable rotation angle for each rotated image to adjust it, and save it after completion; image noise removal is based on multi-view image dense matching technology, and the image data that needs to remove noise is generated into high-density three-dimensional point cloud data, and then the three-dimensional point cloud data is filtered to remove noise and unnecessary points. Multi-view image dense matching technology is a technology that can accurately, automatically and quickly extract required information from multiple image data, and can realize the effective application of image data. By utilizing multi-view image dense matching technology, multiple image data taken by drones can be generated into high-density three-dimensional point cloud data and filtered; three-dimensional point cloud data refers to a set of vectors in a three-dimensional coordinate system, which here represents the spatial position information of objects or scene surfaces in the construction area photographed by the drone; filtering processing refers to removing noise points in three-dimensional point cloud data and improving the accuracy of image data for building more accurate three-dimensional models.

[0016] S2. Import the multiple image data taken and processed by the drone into the model synthesis software, and perform model training based on the multiple image data of the construction area. The process of model training is to generate a three-dimensional model of the construction area through the multiple image data of the construction area. After the model training is completed, the three-dimensional model of the photovoltaic project construction area is obtained; then the processed multiple image data and the three-dimensional model of the construction area are imported into the model square software, and the picture details of the three-dimensional model of the construction area are adjusted according to the multiple image data, wherein the picture details are adjusted by using the detail optimization tool in the model square software to adjust the model's viewing angle and display mode, the model's texture and color, and repair the model's broken surface and wrong edges; and the adjusted three-dimensional model of the construction area is exported in the OBJ format file; then the OBJ format file of the three-dimensional model of the construction area, the multiple image data taken by the drone and the design data are imported into the model management platform, and the three-dimensional model of the construction area is adjusted according to the structural characteristics of the construction area through the real-scene modeling technology. The wall gap is adjusted to obtain the real-scene model of the construction area. Among them, OBJ stands for Object File Format, which is a 3D model file format used to store the geometric information of 3D models, including vertex, edge and face data information; the design data includes: the actual construction plane data of the photovoltaic power station and the power generation related data of the photovoltaic power station, among which the power generation related data includes: the data of the inverter, electric meter and key nodes in the distribution room.

[0017] In this embodiment, in step S2, the real-scene modeling technology is a technology that reflects the real-time operating status and real environment of the photovoltaic power station by constructing a real-scene model of the photovoltaic power station construction area. By using the real-scene modeling technology, the three-dimensional model of the construction area is made to fit more closely, and a high-precision real-scene model of the construction area is obtained. The real-scene model can accurately reflect the data information of the photovoltaic power station construction area, greatly improving the efficiency and accuracy of photovoltaic power station construction.

[0018] S3. Observe the terrain of the construction area through the real-life model of the construction area. Simulate the impact of real weather on the photovoltaic power station under different climates using the real-life model of the construction area, and formulate a construction plan based on the results of observation and simulation. Then, order the materials required for construction through the construction plan, enter the order information of the construction materials into the intelligent warehouse system, and track the order status in real time.

[0019] S4. Carry out construction according to the construction plan. During the construction process, workers wear smart helmets, which are connected to the remote command and dispatch system. The AI ​​recognition function of the smart helmets can be used to reflect the workers' behavior on the big screen in real time through the remote command and dispatch system. At the same time, the workers' behavior can be guided and adjusted in real time. According to the effective time recorded by the smart helmets every day, the workers' wages can be settled in real time every day, and the wages of the day can be automatically paid. In this embodiment, in step S4, the smart helmet worn by the worker is equipped with a camera. During the construction process, the camera will take real-time photos of the environment around the worker, mainly the behavior and status of other workers, and then use the AI ​​recognition function of the smart helmet to identify the behavior and status of the worker. At the same time, through the remote command and dispatch system connected to the smart helmet, relevant personnel can observe the behavior and status of the worker in real time, and provide guidance and adjustments. Through the smart helmet and the remote command and dispatch system, the behavior and status of the workers at the construction site can be reflected in real time, which can further improve the construction progress and quality.

[0020] S5. After the construction is completed, the multiple image data taken by the drone are imported into the VR panoramic production software, and the VR virtual scene of the construction area is obtained through editing and synthesis operations; at the same time, the VR virtual scene of the construction area is uploaded to the cloud platform, and the VR virtual scene is displayed and shared through web pages and mobile devices.

[0021] In this embodiment, in step S5, after the construction is completed, the designers conduct a panoramic acceptance of the construction of the photovoltaic power station through the VR virtual site of the construction area generated by the VR panoramic production software. In the real-scene acceptance system, they can directly click on the constructed photovoltaic power station project and observe the survey, construction and completion VR panoramic views of the construction project. In addition, each photovoltaic power station construction project has supporting documentaries and professional skills videos for project-related personnel to view.

[0022] S6. Based on the VR virtual site of the construction area, project-related personnel can conduct shared operation and maintenance through the shared operation and maintenance system. The shared operation and maintenance system is divided into the owner side and the contractor side. The owner side observes the real-time operation status and power generation of the photovoltaic power station through the monitoring system attached to the shared operation and maintenance system, and can also consult experts online for remote diagnosis; the contractor side can view the distribution, operation health and power generation of the built photovoltaic power stations through the shared operation and maintenance system.

[0023] To sum up, the present invention reduces the cost of manual survey by utilizing drones to collect data on the target area, and fully captures the terrain and landform information of the construction area through the real-life model of the construction area, thereby avoiding design changes caused by the on-site structure and light and shadow of the construction area; at the same time, the unified background command of the remote command and dispatch system can flexibly adapt to the scale and construction scenes of different construction areas, and the core functions and technical architecture of the system are highly versatile, and can be quickly replicated and applied to various photovoltaic power station construction projects, which is significantly progressive.

[0024] The above embodiments are only for illustrating the technical idea of ​​the present invention, and cannot be used to limit the protection scope of the present invention.
