Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconsistency between the actual physical location of photovoltaic strings and their mapped locations in a photovoltaic power station leads to inaccurate operation and maintenance, as the physical map does not accurately reflect the actual positions, hindering efficient maintenance processes.
Innovation Solution
A method and apparatus for updating the physical map by obtaining the actual location of photovoltaic strings using infrared imaging and controlling light intensity to distinguish between strings, and integrating this information with a logical map to ensure accurate mapping, allowing for precise maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the physical map is updated to reflect actual locations, then the accuracy of operation and maintenance is improved, but the complexity of the location management system increases
Solution Approach 1:
The patent uses infrared imaging to create a visual copy of the actual physical locations of photovoltaic strings, which is then integrated with the logical map data. This copying approach allows the system to capture and store location information without requiring complex physical tracking infrastructure, resolving the contradiction between accuracy and system complexity
Solution Approach 2:
The patent introduces an image collection terminal and infrared imaging technology as intermediaries between the photovoltaic strings and the location management system. This intermediary approach enables accurate location detection without requiring direct complex interaction between the management system and each individual photovoltaic string
2Loss of information
If infrared imaging is used to distinguish photovoltaic strings, then the ability to identify actual locations is improved, but the energy consumption and system complexity increase
Solution Approach 1:
The patent implements periodic infrared imaging and location updates rather than continuous monitoring. The system collects images at specific intervals or triggered by maintenance needs, which significantly reduces energy consumption compared to continuous imaging while still maintaining accurate location information when needed
Solution Approach 2:
The infrared imaging creates visual copies of location information that can be stored and reused multiple times without additional energy consumption. Once the location data is captured through imaging, it can be referenced repeatedly for maintenance operations without requiring ongoing energy input

AI summary
A photovoltaic string location update method and apparatus includes: obtaining, based on a physical map, a physical location of a first photovoltaic string corresponding to a first logical location in the physical map, the physical map indicating a correspondence between a logical location of a photovoltaic string and a physical location of the photovoltaic string, and the photovoltaic string includes the first photovoltaic string; and when the physical location of the first photovoltaic string in the physical map is different from a first actual physical location of the first photovoltaic string, updating the physical location of the photovoltaic string in the physical map to the first actual physical location, to obtain an updated physical map. The first actual physical location of the photovoltaic string is inconsistent with the physical location in the physical map, to prepare for subsequent operation and maintenance accurately performed on the photovoltaic string.
