Description

Technical Field

[0001] The present invention relates to the field of mixed reality technology for photovoltaic power station design, and in particular to a photovoltaic power station design phase management system based on a digital twin model management platform. Background Art

[0002] The photovoltaic power station design phase management system based on the digital twin model management platform is a relatively new technology. The system uses mixed reality technology to allow users to interact with virtual objects in the real environment, combining virtual photovoltaic components and systems with the actual environment to achieve precise layout and adjustment, thereby visualizing the layout of future power stations in the real environment. It has many advantages over the traditional photovoltaic power station design phase management method. The traditional photovoltaic power station design phase management method mainly relies on manual planning and design. During the design process, designers need to manually perform various calculations and simulations to ensure that the efficiency and performance of the photovoltaic power station meet the expected goals.

[0003] However, the measures currently taken contain at least the following three problems: 1) Inefficiency: This is because the traditional management method for the design phase of a photovoltaic power station requires designers to manually perform various calculations and simulations, which is prone to errors and difficult to adapt to complex and changing design requirements; 2) Low accuracy: Traditional management methods in the design phase of photovoltaic power stations lack the ability to monitor and analyze data in real time, and are unable to detect problems and make adjustments in a timely manner. However, in actual situations, photovoltaic components need to be accurately laid out and adjusted based on the structural characteristics of the original building and the location of obstacles.

[0004] 3) Poor visualization effect; this is because the traditional management method of the PV power station design phase mainly relies on manual planning and design, and cannot combine virtual PV components with the actual environment to achieve the visualization effect of the project. Summary of the invention

[0005] In response to the above three problems, the purpose of the present invention is to propose a photovoltaic power station design stage management system based on a digital twin model management platform. The system uses digital twin technology and modular management methods to overcome the problems of low efficiency and low model design accuracy in the existing model management platform system; it also uses the project sharing function to promote collaboration and information exchange within the team, reduce communication barriers in the design process, and improve overall work efficiency.
