1Productivity

If manual scanning and binding of product serial numbers is used, then the electronic layout can be obtained, but the labor time consumption is significant and efficiency is low

Engineering Contradiction:
Improveefficiency of obtaining electronic layoutVSAvoidlabor time consumption
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical process of scanning two-dimensional codes and binding serial numbers with an automated image recognition system. The electronic device captures an image of the paper layout and automatically identifies module identifiers and positions through optical character recognition and image processing algorithms, eliminating the need for manual intervention and significantly reducing time consumption.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables the paper layout itself to provide the necessary information automatically. By capturing an image of the paper layout and using automated recognition techniques, the system allows the layout document to self-identify module positions and identifiers without requiring external manual data entry, thereby improving efficiency and reducing labor time.

Inventive Principle:
Principle #25Self-service

2Loss of information

If manual scanning of two-dimensional codes is performed, then product serial numbers can be obtained, but the process is time-consuming and labor-intensive

Engineering Contradiction:

AI summary

This application discloses a method, an apparatus, and a system for obtaining electronic layout applied to photovoltaic array in the field of equipment installation management. According to the method, the electronic device identifies each first area in a target picture to obtain position information and a module identifier of at least one photovoltaic module in each first area, and may directly obtain an electronic layout based on the position information and the module identifier of each photovoltaic module. In this way, a product identifier of each converter does not need to be manually obtained, and a photovoltaic module does not need to be manually added to the electronic layout. This reduces labor time consumption and improves efficiency of obtaining the electronic layout.
